Scientists have come up with the best computer model to date of the universe, one which maps the evolution of the cosmos in unprecedented detail. Known as Illustris, this virtual cosmos – which was created by U.S., English and German researchers using a network of supercomputers – includes details never before achieved in a simulation. All told, the numerical-based model covers the 13-billion-year evolution of the universe, beginning just 12 million years after the Big Bang took place.
While cosmologists have been developing and employing computer models of the universe for several decades, the outcome is usually a rough approximation of the universe that scientists observe in reality. Illustris, however, has produced a universe that looks uncannily like the real on. Among other things, it models how the universe expands, how galaxies are formed, their composition and distribution, and the mechanics of how stars and black holes are formed.
Given all the recent breakthroughs in physics and cosmology, this ultra-detailed virtual model should come as no surprise. For example, this past April, scientists made not only made the first-ever observation of gravitational waves, they also processed data that is believed to be the first real indication of the existence of Dark Matter. In addition, the ESA’s Planck mission released the most detailed thermal imaging map of the universe last year that placed an accurate date on the universe’s age and confirmed the validity of the Big Bang Theory.
The Illustris creators say it represents “a significant step forward in modelling galaxy formation”, and provides a good visual representation of our ever-expanding (no pun!) understanding of the universe. A recent article that appeared last Wednesday in the journal Nature describes Illustris, and several videos (like those below) have been released that show the simulation in action. Check them out below:
For ideal physical rehab, it might be necessary to go a little “cyborg”. That’s the reasoning a Chinese biomedical firm used to develop a new method of repairing damaged nerve endings. Borrowing a page from Terminator 2, their new treatment calls for the use of liquid metal to transmit nerve signals across the gap created in severed nerves. The work, they say, raises the prospect of new treatment methods for nerve damage and injuries.
Granted, it’s not quite on par with the liquid-metal-skinned cyborgs from the future, but it is a futuristic way of improving on current methods of nerve rehab that could prevent long-term disabilities. When peripheral nerves are severed, the loss of function leads to atrophy of the effected muscles, a dramatic change in quality of life and, in many cases, a shorter life expectancy. Despite decades of research, nobody has come up with an effective way to reconnect them yet.
Various techniques exist to sew the ends back together or to graft nerves into the gap that is created between severed ends. And the success of these techniques depends on the ability of the nerve ends to grow back and knit together. But given that nerves grow at the rate of one mm per day, it can take a significant amount of time (sometimes years) to reconnect. And during this time, the muscles can degrade beyond repair and lead to long-term disability.
As a result, neurosurgeons have long hoped for a way to keep muscles active while the nerves regrow. One possibility is to electrically connect the severed ends so that the signals from the brain can still get through; but up until now, an effective means of making this happen has remained elusive. For some time, biomedical engineers have been eyeing the liquid metal alloy gallium-indium-selenium for some time as a possible solution – a material that is liquid at body temperature and thought to be entirely benign.
But now, a biomedical research team led by Jing Liu of Tsinghua University in Beijing claims they’ve reconnected severed nerves using liquid metal for the first time. They claim that the metal’s electrical properties could help preserve the function of nerves while they regenerate. Using sciatic nerves connected to a calf muscle, which were taken from bullfrogs, they’ve managed to carry out a series of experiments that prove that the technique is viable.
Using these bullfrog nerves, they applied a pulse to one end and measured the signal that reached the calf muscle, which contracted with each pulse. They then cut the sciatic nerve and placed each of the severed ends in a capillary filled either with liquid metal or with Ringer’s solution – a solution of several salts designed to mimic the properties of body fluids. They then re-applied the pulses and measured how they propagated across the gap.
The results are interesting, and Jing’s team claim that the pulses that passed through the Ringer’s solution tended to degrade severely. By contrast, the pulses passed easily through the liquid metal. As they put it in their research report:
The measured electroneurographic signal from the transected bullfrog’s sciatic nerve reconnected by the liquid metal after the electrical stimulation was close to that from the intact sciatic nerve.
What’s more, since liquid metal clearly shows up in x-rays, it can be easily removed from the body when it is no longer needed using a microsyringe. All of this has allowed Jing and colleagues to speculate about the possibility of future treatments. Their goal is to make special conduits for reconnecting severed nerves that contain liquid metal to preserve electrical conduction and therefore muscle function, but also containing growth factor to promote nerve regeneration.
Naturally, there are still many challenges and unresolved questions which must be resolved before this can become a viable treatment option. For example, how much of the muscle function can be preserved? Can the liquid metal somehow interfere with or prevent regeneration? And how safe is liquid metal inside the body – especially if it leaks? These are questions that Jing and others will hope to answer in the near future, starting with animal models and possibly later with humans..
Welcome back to the latest edition on the Williams’ Family Eurotrip 2014! Today, in what I hope will be the second-last post in this segment, I will be covering some of my favorite aspects of the trip. These included our visit to the Caen Memorial Museum, our overnight in Chartres, and our arrival in Paris which was accompanied by some very interesting times in the Latin Quarter. Here’s how it all well down…
Friday, April 18th – Sunday, April 20th – Caen and Chartres and Paris: The day started with us packing up and saying goodbye to the Lion D’Or, which for the past few days had been our home away from home, complete with feline company! Then, we hit the road on our way to Chartres; and unlike previous days, we only made one stop along the way. However, it was an important stop, since it was the last stop on our tour of World War II sites and memorials. Initially, we had talked about visiting the Ardennes Abbey, where 20 Canadian POWs had been murdered by SS troops on July 8th, 1944.
The Abbey has since been converted into a museum that pays homage to these individuals and commemorates the sacrifices made by countless people during the Battle of Normandy. However, my father had visited it twice now and cautioned that it was quite depressing. So instead, we decided to detour through the northern part of Caen to visit the Mémorial deCaen, a museum and memorial which was by far the largest and most detailed museum we had seen on the trip.
Mémorial de Caen, map out front of all the events around Caen during the Battle of Normandy 1944
Outside the museum, we found a lovely map where I concluded explaining the events surrounding the Battle of Caen – one of the most intensive battles to take place during Operation Overlord and the liberation of France. This proved to be a good time to share what I knew, since the museum was immensely more detailed on the subject and would have made my little talk pointless! And picking up where we had left off during our visit to Juno Beach and the Normandy countryside, I began sharing with my wife and olks exactly how hard it had been in 1944 to take the city.
Initially a D-Day objective, it would take the British, Canadian and Allied forces a total of 45 days to secure the city of Caen. Its strategic position in the Eastern Sector of Normandy, as well being a major crossing point over the Orne river, made capturing it an absolute necessity. To the Allies, taking the city was a matter of securing a solid beachhead and preventing a German counter-attack. To the Germans, holding it was a matter of ensuring that the Allied forces would be denied the ability to venture father south.
In June, the Canadian 3rd Division managed to secure the high ground to the west and south-west of the city, including the towns of Carpiquet, Authrie and Rots. To the north, the British I Corps had also seized all land outside of the city, but still faced tough resistance from the German 12th SS Panzers, the 21st Panzer Division, and the 716th Infantry Division. Since their attempt to take the city by a direct assault on D-Day had failed, General Montgomery now looked to take the city with a pincer movement.
Thus began Operation Perch, which commenced on the 7th of June (D-Day+1) and aimed at achieving a breakout west around Bayeux. As the I Corps attacked the town of Cagny some 5 km south-east of Caen, the British XXX Corps (located 20 km to the west) would push south of Bayeux and cross the Odon river, in an attempt to outflank the Germans south of the city. Almost immediately, the attack ran into problems, which would force further delays in liberating Caen.
In the west, the XXX Corps was delayed after reaching the town of Tilly-sur-Seulles, where they became bogged down by hedgerows and stiff resistance from the 12th SS Panzers and the Panzer-Lehr Division – an elite unit with many of Germany’s most advanced tanks (such as the Panzer V “Panther” tank, pictured above). In the east, the I Corps’ advance was stalled thanks to tough resistance from the battle-hardened 21st Panzer Division. By the 13th of June, the offensive was called off.
However, on the following day, the German line broke to the west of the XXX Corps, thanks to the efforts of the American 1st Infantry Division (Big Red One). After withdrawing south, the Germans opened a 12 km gap in their lines, which the British 7th Armored Division sought to exploit by pushing south. In an attempt to outflank the Panzer-Lehr Division, the 7th Armored aimed to capture the town of Villers-Bocage some 15 kms south of Bayeux.
However, the British once again experienced severe resistance and after two days of intense fighting, they fell back on June 14th. It was hoped that with some reinforcements, they would resume the attack on the 19th and push through. However, a terrible storm fell on the English Channel, which caused severe disruption to beach supply operations and damaged the artificial harbor at Arromanches (see “Part the Fourth”, specifically the stuff dealing with Mulberry Harbor).
Because of this, offensive operations were postponed until July, at which point, General Montgomery would once again plan to seize Caen by a direct assault. The first phase of this assault was known as Operation Windsor, and called for the Canadian and British forces west of Caen to retake the town of Carpiquet from the 12th SS and then secure the Carpiquet Airfield to the south. The second phase, known as Operation Charnwood, would see the I Corps clearing the north end of Caen and seizing the bridgeheads into the southern part of the city.
On July 4th, the attack commenced, with Canadian and British forces braving mines, anti-tank guns, and machine gun nests to take Carpiquet. By the following day, the town had been secured and several German counterattacks had been repulsed. By July 8th, acting on intelligence provided by the French Resistance, the Canadian and British forces marched on the airfield and found it abandoned. Operation Windsor was a success.
Operation Charnwood, by contrast, met with limited success, and caused significant damage to the city of Caen. On July 7th, the began with a massive aerial bombardment where the first wave of bombers dropped over 1,800 tons of munitions on the city. The Allies hoped to minimize civilian deaths by dropping leaflets prior to the bombing. However, the drop took place just a day prior, and due to complications caused by the weather, only a few thousands leaflets reached their destination and only a few hundred townspeople left.
On the following morning, the I Corps mobilized and reached the outskirts of town by nightfall. The Germans immediately began evacuating across the Orne river, leaving elements of their forces behind to fight a rearguard action in the rubble-filled streets. Despite fierce resistance, the English and Canadian forces secured the northern half of Caen by the 9th of July and decimated the 16th Luftwaffe Field Division. However, the bridges across the Odon were not secured, and were either blocked by rubble or heavily defended from the south bank.
Because of this, the Operation was called off by the 9th of July since no further gains were possible. Though it had been delcared a success, Caen was not yet fully liberated and the city had suffered extensive damage. It’s civilian population which had been roughly 60,000 before the battle – had now dropped to 17,000, which caused widespread resentment towards the liberators. Nevertheless, the townspeople in the northern half of the city still came out in force to celebrate the defeat of the Germans.
Later than month, Monty once again planned to take the rest of the city with a pincer movement. Known as Operation Atlantic, this assault involved the 3rd Canadian Infantry Division advancing to the east of Caen to secure the suburb of Colombelles while the 2nd Canadian Infantry Division drove south to seize the high ground of Verrieres Ridge. Once again, these assaults would coincide with a British offensive farther east. On the 18th and 19th of July, the Canadian 3rd Division managed to secure the town of Colombelles from the 21st Panzers and drove them over the Orne river, effectively liberating all of Caen.
Unfortunately, the 2nd Division was stalled while trying to take Verrieres Ridge, thanks in part to heavy rains that turned the ground to mud – which bogged down their armor support and grounded the RAF – and because the Germans were well fortified and had artillery support. After several days of fighting, the 2nd Division fell back and were reinforced by elements of the 3rd Divisions; and together, they were able to halt the counter-attacks launched by the 12th SS Panzers.
Meanwhile, the I and VIII British Corps initiated Operation Goodwood on July 18th, which sought to capture the town of Bourguébus and the high ground south of the city. Once again, the operation was preceded by extensive bombing, which harried the German forces that had fallen back from Caen. However, the advance stalled due to numerous factors and the British lost the element of surprise. For starters, the British only had six bridges over the Orne river, which slowed the crossing of the 1000+ vehicles taking part in the offensive considerably.
Once they reached the other side, they were forced to contend with minefields that had been lain by the 51st Highland Division to defend their positions just a few days prior. But since the element of surprise was already lost, British command decided to order the mines cleared. Two days later, the attack resumed. However, the Germans had recovered from the bombing by then, and the British were forced to clear several well-defended towns that were connected by underground tunnels.
In addition, the German artillery on Bourguébus ridge had not been destroyed by the Allied bombing. And thanks to their numerous observation posts stationed throughout the villages in the region, they were able to observe the British advance and call in artillery support on their armor. Between the 18th and the 20th, they also mounted numerous counter-attacks, and by the end of the day, Montgomery brought the operation to a close, citing bad weather.
All told, Goodwood did not go as planned and was a failure in terms of achieving a breakout. Some 4000-5000 Allied troops and 250-350 tanks were also lost in the assault. The German losses are unknown, but some 2500 men were captured (mostly by the British since the Canadians were no longer taking SS prisoners) and between 75 and 100 tanks were destroyed. However, these two operations did manage to secure important strategic ground, liberated the rest of Caen, and effectively bled the Germans dry in the region.
But most importantly of all, the sustained British, Canadian and Allied efforts in and around Caen managed to tie down four German Corps, which included important armored divisions, while the Americans were planning their own breakout to the west. On July 25th, just one day after the Canadians and British were told to dig in, the 1st US Army launched Operation Cobra, which effectively achieved a breakout around the town of Saint-Lô.
This breakout would allow the American forces to drive south and east, effectively outflanking what was left of the German forces, while the British 2nd Army – with the Canadian 4th and 1st Polish Armored Divisions leading the way – closed in on them from the north. This encirclement maneuver, which would come to be known as the Battle Falaise Pocket, effectively decimated what was left of the German army and signaled the liberation of France. Thereafter, the Allies would advance onto Paris and by the 30th of August, they were marching down the Champs d’Elysee. A massive crowd of jubilant Parisians turned out to welcome their arrival, and the liberation of France was declared.
Mémorial de Caen, out front afterwards
All of this and more was covered in beautiful detail inside the museum, which began with a movie called “”. We then proceeded through a series of rooms with pictures, artifacts, infographics and write-ups that explained every aspect of the war – ranging from the prelude and the build-up to every event that took place between 1939 and 1945. And of course, considerable space and resources were committed to the aftermath, which included the Cold War, Peacekeeping, and war in peace in the modern world.
The entire experience then closed with a movie entitled “Hope”, which gave an audio-visual rundown of the conflicts and major historical events that have taken place since 1945. And though the tone of the movie didn’t seem particularly hopeful, it seem to contain some hints that lessons had been learned and the state of the world had improved somewhat since. At least, that was the impression I chose to take away, others in our party disagreed.
The Cathedral of Chartres in the distance
And then, it was on to Chartres, lock, stock and barrel! Compared to the town where we spent the previous week and a half, this city was significantly bigger. As such, it took some time to navigate through the morass of major streets and burbs before we finally came to the old town, which is instantly identifiable by the ancient stone wall and mote that surround it, not to mention the fact that it sits on the high-ground. And in the distance, we could see the spires of the looming at the crest of the hill.
Once inside the walls, the streets instantly narrowed, and getting to our hotel – which was awesomely located next to the Cathedral – involved going along some winding back-streets that proceeded ever uphill. Betty (our GPS) had some issues, mainly because the tight streets and high walls made it hard for her to get a signal. And yet, we somehow found our way to the top and street with our hotel on it. And once we had unpacked and entered, the nice lady who ran the place took on another climbing adventure.
The moat that surrounds the old city
Basically, this hotel (which overlooks the Cathedral) is a narrow, stacked house. On the ground floor, there’s the restaurant and bar, with the rooms stacked vertically above and below it. My folks were in the room one floor up, while Carla and I got the appropriately-named “Ange” room (Angel) that was at the very top, and had the best view of the Cathedral. It also had something we hadn’t seen in days and were looking forward to using – a tub with jets!
The room was also very traditional looking – with wallpaper that looked like plaster coating and old wooden beams in the ceiling that woke us up with their creaking! My folks room was a little different. In addition to a strange 80’s deco scheme, it had a circular bed, a stand-up shower and no tub, and a wall-mounted fire place that took some time to figure out. In fact, it wasn’t even immediately apparent that it WAS a fireplace.
The Cathedral entrance
After unpacking and uncorking the cider and Calvados in our room (an experience that left us a little shaken), the four of us proceeded to take a walk around the Cathedral before having dinner. In many ways, the Chartres Cathedral was similar to what we had seen in Ypres and Bayeux – in that their designs were a combination of Romanesque and Gothic architecture. This is owing to their immense longevity and the fact that they’ve been renovated and had additions put on over the centuries.
However, Chartres was bigger by comparison, and had what my father noted were true examples of flying buttresses. Did I mention he’s an architect? That kind of seems like something worth mentioning. In any case, these are basically load-bearing arches that are attached to the outside of the building, a common feature in Gothic cathedrals. And this baby had plenty of them! And of course, the stain-glass windows – which according to information provided inside contain the first blue glass ever made – were breathtakingly impressive.
The stained-glass windows located at the Nave
After noting the labyrinth pattern on the stone floor – and some strange symbols in the center of it that we joked were evidence of the da Vinci Code – we walked around to the Nave (my father pointed out all the architectural features and names) and noticed the stone wall that was covered with intricate carvings. We also noted the renovations that were taking place, where the columns and stonework were all getting a “facelift”. This amounted to stripping the top layers off to remove the 1000+ years worth of soot that had built up them.
To save time, I should also note that we came back the next day and scale the steps of the bell tower. This is something you have to pay for, but we seriously wanted to mount those 350 steps to take in the view. And so we could say we did it! Now let me tell you, scaling a Gothic Cathedral’s 350-step winding staircase is no picnic! The going was cramped, the air moldy, and the steps a little slippery. Still, we couldn’t help but feel we were breathing in centuries of history, even if it did cause some coughing afterward.
Carla at the top of the bell tower
At the top, we got a bird’s eye view of the old section of town, not to mention the new town and the countryside beyond. Once again, there were plenty of golden canola fields to be seen between grassy fields. And of course, we got a pretty good close-up of the flying buttresses, gargoyles and other Gothic external features. And then, we descended, which proved to be almost but not quite as difficult as going up. We also watched the Cathedral fill with people as the locals prepared for the Easter Sunday service.
Getting back to the night before, we then had dinner at the restaurant, which had an interesting feature of the menu. My mother spotted “Filet de Loup”, which roughly translates to “filet of wolf”, or so we thought. Naturally, we were a little concerned and suspected we might have wandered into a cultural difference. But our server resolved this when she explained that this is actually the name for a whitefish filet, and found our misunderstanding to be quite perplexing. Seriously, she looked at us like we were on drugs!
The light show on the Cathedral facade that took place that night
My wife and mother had the lasagna, which they didn’t really like, while my father enjoyed the filet de loup, and I enjoyed a filet of monkfish with chorizo. This was all washed down with glasses of Affligem, which were necessary after the Caldavos incident. And then, we popped back outside because we noticed an interesting light show happening on the front of the cathedral. At first, we thought someone was throwing rolls of TP down the front. But upon closer inspection, it turned out to be a dazzling visual display that was being projected onto the facade.
We snapped some photos of the show, but as you can see, they didn’t turn out to well owing to the need for low light to capture all the vivid colors. Then it was back to our rooms, a nice hot bath, and a sound sleep. Well, mostly sound, since the popping noise in the ceiling did wake us up and one point and make us wonder if the old building was about to fall down around our ears. Lucky for us, it didn’t, and the popping noises abated long enough for us to get back to sleep.
l’Academie de la Biere
In the morning, we packed up (mournfully), did our second tour of the Cathedral (complete with the stair climb), and then said good-bye to the hotel. While we waited for my father to secure the car from a lot down the road, I spotted a building that bore the name “l’Academie de la Biere”, which I suspected was a bar with some serious taps and bottles. I ventured down to snap some photos of it. Too bad we hadn’t noticed it the night before!
And then, with the car packed and the bill paid, we set off for Paris! Our first stop was the Charles de Gaulle Airport where we needed to return the car. Our time in Paris would be spent car-free, as we knew that public transit there is quite extensive, and to drive there is to take one’s life in one’s hands! Predictably, getting into the airport was about as hard as getting out, and it took a few roundabouts on the highway to get to the rental lot on the bottom level.
Us on the train from CDG Airport to Paris
From the airport, we hopped the train into the city, where he began subway surfing from train to train. It was here that we came to understand exactly what is meant by “mass transit”, which in Paris equates to the crush of humanity trying to make its way through congested platforms, trains and tunnels. And we had all our bags with us, to boot, which were quite heavy. Wanting to be the good son, I carried a few heavy bags, and was offered help repeatedly.
Eventually, to end the flurry of concern and proferred aid, I said: “The next person who offers me help will be mentioned, by name, in the suicide note.” That’s not an original quote, fyi, and it didn’t quite get the laughs I was hoping for. And after much hauling and walking, we eventually found our exit and ascended into the Paris city streets. From there, we walked the few blocks that would take us to our hotel in the Latin Quarter – la Hôtel des Grandes Ecoles.
Hotel Grandes Ecoles Courtyard
I’ll be honest, our rooms were a bit tight, but the hotel did have a lovely courtyard paved with cobblestones. And not far away, there was a lovely roundabout with plenty of restaurants, all of which had extensive patios that faced the fountain in the middle. We took a look at all this and selected one based on my wife’s craving for nachos. It was called la Petit , a place that specialized in gourmet burgers and did make a good nacho plate. Instead of sour cream and cheddar, they used crème fraîche and melted Emmental.
Much like in Bayeux, we would dine here twice. Some places just make a lasting impression I guess! Oh, and the beer of choice around the Latin Quarter was yet another Abbey Blonde ale known as Grimbergen, though Kronenbourg certainly got top billing at the local bars as well. With our bellies full and our feet and backs tired of walking and carrying bags, we once again retired for the night and planned for a full day of adventure on the morrow.
La Seine, with the Notre Dame de Paris Cathedral in the distance
This consisted of us taking a walk down to the Seine to take in all the sights and sounds of Paris. We arrived on Quai St. Bernard, with the Cathedral of Notre Dame to the west by a few leagues. We headed their immediately, and found some serious crowds assembled out front. Since it was Easter Weekend, there was quite a lineup to get in, and we decided we’d have to wait until another day to see the place from the inside. So instead, we decided to catch a bus to see all of the major sights in one afternoon.
As a sidenote, people looking to book a Paris bus tour have the option of doing a single 2 hour roundabout trip, or a day-long trip that where people can jump on and off the bus at any of the major sights. We opted for the former, and rode around on a double-decker and listened to a audio guide through uncomfortable earbuds tell us about what we were seeing. These included the Musee d’Orsay, the Place de Concorde, the Tour Eiffel, the Champs d’Elysee, the Arc de Troimphe, the Hotel des Invalides, the Louvre, the Pont d’Alexandre III, the Galerie Lafayette, the Opera Nationale, the Écoles Militaires, the Field of Mars, and the Hotel des Invalides, amongst others…
Streets of the Latin Quarter
I shall NOT be giving historical background on all of these. Suffice it to say, this blog aint long enough and you people know how to use Google. But I will say, the roundabout tour was fun, scenic, and really drives home the fact that Paris is packed to the gills with heritage and living examples of its long and turbulent history. Seriously, one cannot drive or walk down the street without spotting a plaque, monument or statue that tells the story of something immensely significant that happened there.
Afterwards, we returned to our hotel and met a lovely man named Jaeger. This attorney, who hailed from Australia, was in Paris on business, and after being chatted up by my father, invited us to dinner. The place he took us was a few blocks over from the hotel, and was rather famous! Known as the Maison de Verlaine, a restaurant that is famous for having been frequented by countless literary, political and showbiz personalities – like Hemingway, Marilyn Monroe and the Kennedy’s, to name a few.
La Maison de Verlaine, where we ate Sunday night
And after a rather sumptious meal and a bottle of red that was both subtle and robust, we dropped Jaeger off at a bar in the roundabout near our hotel and retired to our beds for some sleep. Having toured all the major sights that day, we decided we would visit those we were particularly intrigued by on the following day. Only this time, we’d be going by foot and we planned to beat the lines. We had only a few days to go, and planned to see as much as we possibly could before our departure.
But more on that next time. I sincerely hope it’s the last! 😉
DC Animated Original Movies has put out some fairly decent flicks in recent years, especially when it comes to the Batman universe. These include Batman: Gotham Knight, Batman: Under the Red Hood, Batman: Year One, and Batman: The Dark Knight Returns. And in this latest installment, which is based on the popular Batman: Arkham video game franchise, we see Batman and the Suicide Squad team up to take down the Joker and stop him from blowing up the asylum and Gotham City.
In anticipation of its upcoming release, which is scheduled for August 12, 2014, DC Entertainment released the following teaser trailer a few weeks ago. I just stumbled onto it myself, and so I pass it on to all those fellow fans who – if they are like me – would not dare miss this! Enjoy!
During my usual morning consultation of my email and internet subscriptions, I came across a new video by ERP. In this latest showdown, which is once again pop-culture gold, we get cable TVs most popular fathers – Rick Grimes of The Walking Dead and Walter White of Breaking Bad. What better way to generate comedy than to match up a post-apocalyptic dad who was forced to kill his wife’s reanimated corpse, and a chemist who began cooking meth to ensure his family’s future and then became a ruthless kingpin?
And as usual, Nice Peter and EpicLLOYD are just awesome in their roles! Seriously, they just BECOME whoever they’re imitating. Enjoy!
The nation of Japan has long been regarded as being at the forefront of emerging technology. And when it comes to solar energy, they are nothing if not far-sighted and innovative. Whereas most nations are looking at building ground-based solar farms in the next few years, the Japanese are looking at the construction of vast Lunar and space-based solar projects that would take place over the course of the next few decades.
The latest proposal comes from the Japan Aerospace Exploration Agency (JAXA), which recently unveiled a series of pilot projects which, if successful, should culminate in a 1-gigawatt space-based solar power generator within just 25 years. Relying on two massive orbital mirrors that are articulated to dynamically bounce sunlight onto a solar panel-studded satellite, the energy harvested would then be beamed wirelessly to Earth using microwaves, collected Earth-side by rectifying antennas at sea, and then passed on to land.
JAXA has long been the world’s biggest booster of space-based solar power technology, making significant investments in research and rallying international support for early test projects. And in this respect, they are joined by private industries such as the Shimizu Corporation, a Japanese construction firm that recently proposed building a massive array of solar cells on the moon – aka. the “Lunar Ring” – that could beam up to 13,000 terawatts (roughly two-thirds of global power consumption) to Earth around the clock.
Considering that Japan has over 120 million residents packed onto an island that is roughly the size of Montana, this far-sighted tendency should not come as a surprise. And even before the Fukushima disaster took place, Japan knew it needed to look to alternative sources of electricity if it was going to meet future demands. And considering the possibilities offered by space-based solar power, it should also come as no surprise that Japan – which has very few natural resources – would look skyward for the answer.
Beyond Japan, solar power is considered the of front runner of alternative energy, at least until s fusion power comes of age. But Until such time as a fusion reaction can be triggered that produces substantially more energy than is required to initiate it, solar will remain the only green technology that could even theoretically provide for our global power demands. And in this respect, going into space is seen as the only way of circumventing the problems associated with it.
Despite solar power being in incredible abundance – the Earth’s deserts absorb more energy in a day than the human race uses in an entire year – the issue of harnessing that power and getting it to where it is needed remain as stumbling blocks. Setting up vast arrays in the Earth’s deserts would certainly deal with the former, but transmitting it to the urban centers of the world (which are far removed from it’s deserts) would be both expensive and impractical.
Luckily, putting arrays into orbit solves both of these issues. Above the Earth’s atmosphere, they would avoid most forms of wear, the ground-based day/night cycle, and all occluding weather formations. And assuming the mirrors themselves are able to reorient to be perpetually aimed at the sun (or have mirrors to reflect the light onto them), the more optimistic estimates say that a well-designed space array could bring in more than 40 times the energy of a conventional one.
The only remaining issue lies in beaming all that energy back to Earth. Though space-based arrays can easily collect more power above the atmosphere than below it, that fact becomes meaningless if the gain is immediately lost to inefficiency during transmission. For some time, lasers were assumed to be the best solution, but more recent studies point to microwaves as the most viable solution. While lasers can be effectively aimed, they quickly lose focus when traveling through atmosphere.
However, this and other plans involving space-based solar arrays (and a Space Elevator, for that matter) assume that certain advances over the next 20 years or so – ranging from light-weight materials to increased solar efficiency. By far the biggest challenge though, or the one that looks to be giving the least ground to researchers, is power transmission. With an estimated final mass of 10,000 tonnes, a gigawatt space solar array will require significant work from other scientists to improve things like the cost-per-kilogram of launch to orbit.
It currently costs around $20,000 to place a kilogram (2.2lbs) into geostationary orbit (GSO), and about half that for low-Earth orbit (LEO). Luckily, a number of recent developments have been encouraging, such as SpaceX’s most recent tests of their Falcon 9R reusable rocket system or NASA’s proposed Reusable Launch Vehicle (RLV). These and similar proposals are due to bring the costs of sending materials into orbit down significantly – Elon Musk hopes to bring it down to $1100 per kilogram.
So while much still needs to happen to make SBSP and other major undertakings a reality, the trends are encouraging, and few of their estimates for research timelines seem all that pie-eyed or optimistic anymore.
This Tuesday, the Whitehouse received the latest draft of the Climate Assessment Report, a scientific study produced by the National Climate Assessment to determine the impacts of Climate Change. In addition to outlining the risks it poses to various regions in the US, the report also addresses the apparent increase in the number of severe weather events that have taken place in the past few years, and how these events affect local economies and communities.
According to the 840-page report, America is fast becoming a stormy and dangerous place, with rising seas and disasters effecting regions from flood-stricken Florida to the wildfire-ravaged West. The report concluded that Climate change’s assorted harms “are expected to become increasingly disruptive across the nation throughout this century and beyond.” It also emphasized how warming and its all-too-wild weather are changing daily lives, even using the phrase “climate disruption” as another way of saying global warming.
Henry Jacoby, co-director of the Joint Program on the Science and Policy of Global Change at the MIT, was joined by other scientists and White House officials when he claimed that this is the most detailed and U.S.-focused scientific report on global warming. Above all, the most chilling claim contained within is the fact that “Climate change, once considered an issue for a distant future, has moved firmly into the present.”
The report also examined the effects at the regional and state-level, compared with recent reports from the UN that examined North America as a single case study. In a recent interview with CBC’s The Lang & O’Leary Exchange, Jacoby pointed to a range of impacts of global warming that people see everyday, from the change in the growing season, to extreme heat, severe Atlantic storms and drought in some areas.
As he explained, these changes are far more than just variable weather:
If you look at what’s happening to the Arctic ice at your northern border, you are seeing changes to the ice like you haven’t seen in hundreds of years. We’re seeing change on a scale that’s going beyond variability.
A draft of the report was released in January 2013, but this version has been reviewed by more scientists, the National Academy of Science, 13 other government agencies, and was subject to public comment. It is written in a bit more simple language so people could realize “that there’s a new source of risk in their lives,” said study lead author Gary Yohe of Wesleyan University in Connecticut.
Even though the nation’s average temperature has risen by as much as 1.9 degrees since record keeping began in 1895, it’s in the big, wild weather where the average person feels climate change the most. As the report’s co-author Katharine Hayhoe – a Texas Tech University climate scientist – put it, extreme weather like droughts, storms and heat waves hit us in the pocketbooks and can be seen by our own eyes. And it’s happening a lot more often lately.
The report says the intensity, frequency and duration of the strongest Atlantic hurricanes have increased since the early 1980s. Winter storms have increased in frequency and intensity and shifted northward since the 1950s, with heavy downpours increasing by 71 per cent in the northeast alone. Heat waves are projected to intensify nationwide, with droughts in the southwest expected to get stronger. Sea levels have risen 20 centimetres since 1880 and are projected to rise between 0.3 meters and 1.2 metres by 2100.
The report was also clear that the 2010’s have been a record-setting decade. For example, since January 2010, 43 of the lower 48 states have set at least one monthly record for heat, such as California having its warmest January on record this year. In the past 51 months, states have set 80 monthly records for heat, 33 records for being too wet, 12 for lack of rain and just three for cold, according to an Associated Press analysis of federal weather records.
As she described it, America is basically in a boxing match, and is currently on the ropes:
We’re being hit hard. We’re holding steady, and we’re getting hit in the jaw. We’re starting to recover from one punch, and another punch comes.
John Podesta, an adviser to President Barack Obama, said on Monday that the report includes “a huge amount of practical, usable knowledge that state and local decision-makers can take advantage of.” The report also stressed that climate change threatens human health and well-being in a number of ways. Those include smoke-filled air from more wildfires, smoggy air from pollution, more diseases from tainted food, water, mosquitoes and ticks.
And then there’s more pollen because of warming weather and the effects of carbon dioxide on plants. Ragweed pollen season has lengthened by 24 days in the Minnesota-North Dakota region between 1995 and 2011, the report says. In other parts of the Midwest, the pollen season has gotten longer by anywhere from 11 days to 20 days. And all of this has associated costs, not the least of which is in damages, insurance costs, and health care expenses.
Flooding alone may cost $325 billion by the year 2100 in one of the worst-case scenarios, with $130 billion of that in Florida, the report says. Already the droughts and heat waves of 2011 and 2012 added about $10 billion to farm costs, the report says. Billion-dollar weather disasters have hit everywhere across the nation, but have hit Texas, Oklahoma and the southeast most often, the report says. And there is the impact on agricultural producers, which is also stressed:
Corn producers in Iowa, oyster growers in Washington state and maple syrup producers in Vermont are all observing climate-related changes that are outside of recent experience.
Still, it’s not too late to prevent the worst of climate change, says the 840-page report, which the White House is highlighting as it tries to jump-start often stalled efforts to curb heat-trapping gases. However, if the U.S. and the world don’t change the way they use energy, the current effects will continue to intensify to the point where property damage, wildfires, storms, flooding and agricultural collapse will become untenable.
Already, the report has its detractors, many of whom appeared together for a Special Report segment on Fox News. In addition to commentator George Will questioning the scientific consensus – which accounts for 97% of the scientific community – Charles Krauthammer compared to the findings to a bargaining process, and ultimately condemned it as “superstition”. As he put it:
What we’re ultimately talking about here is human sin, through the production of carbon. It’s the oldest superstition around. It was in the Old Testament. It’s in the rain dance of the Native Americans. If you sin, the skies will not cooperate. This is quite superstitious and I’m waiting for science that doesn’t declare itself definitive but is otherwise convincing.
Not to belabor the point, but superstition is what happens when people trust in rituals and practices that have no discernible effect whatsoever on a problem to protect themselves from said problem. Conducting research, performing field studies, and compiling statistics that cover hundreds, thousands, and even millions of years – this is called the scientific method. And Krauthammer would do well to realize that it is this same method that has done away with countless superstitious rituals throughout history.
He and other so-called skeptics (though a more accurate term is deniers) would also do well to understand the difference between superstition and a little thing known as cause and effect. For example, avoiding black cats, not walking under ladders, or sacrificing human beings to make the sun rise or the crops grow is superstition. Pumping thousands of tons of carbon dioxide into the air, which is known to have the effect of absorbing the sun’s thermal energy (aka. radiant forcing), is cause and effect.
See? Easily distinguished. But if there’s one thing that the “denial machine” has shown an affinity for, its remaining divorced from the scientific consensus. Luckily, they have been in full-retreat for some time, leaving only the most die hard behind to fight their battles. One can only hope their influence continues to diminish as time goes on and the problems associated with Climate Change get worse.

April was a busy month for the very photo-talented (and photogenic) Curiosity Rover. In addition to another panoramic shot of the Martian landscape – which included Curiosity looking back at itself, making it a “selfie” – the rover also managed to capture a night-sky image that captured two minor planets and the Martian moon of Deimos in the same picture. At a time when Curiosity and Opportunity are both busy on long-haul missions to find evidence of life, these latest pictures remind us that day-to-day operations on Mars are still relevant.
The first shot took place on April 20th (Sol 606), when rover scientists used the Mast Camera to capture the minor planets of Ceres and Vesta, as well as the moon of Deimos, in the same frame. Ceres is a minor planet with a diameter of about 950 km, and is the largest object in the main asteroid belt. With a diameter of about 563 km, Vesta is the third-largest object in the asteroid belt. Deimos, meanwhile, is the smaller of Mars’ two moons, with a mean radius of 6 km.
In the main portion of the new image (seen above), Vesta, Ceres and three stars appear as short streaks due to the duration of a 12-second exposure. In other camera pointings the same night, the Curiosity’s camera also imaged Phobos and the planets Jupiter and Saturn, which are shown as insets on the left. Dr Mark Lemmon from Texas A&M University, a Curiosity team member, explained:
this imaging was part of an experiment checking the opacity of the atmosphere at night in Curiosity’s location on Mars, where water-ice clouds and hazes develop during this season… The two Martian moons were the main targets that night, but we chose a time when one of the moons was near Ceres and Vesta in the sky.
Deimos was much brighter than the visible stars, Vesta and Ceres in the same part of the sky, in the main image. The circular inset covers a patch of sky the size that Earth’s full moon appears to observers on Earth. At the center of that circular inset, Deimos appears at its correct location in the sky, in a 0.25 second exposure.
As for the latest in Curiosity’s long-line of panoramic self-portraits, this one comes to us courtesy of Jason Major. As a graphic designer and amateur space explorer, Major assembled the picture from about the dozen or so images acquired with the rover’s Mars Hand Lens Imager (MAHLI) instrument on April 27-28, 2014 (Sol 613). In the background, one can see the 5.5-km-high (3.4 miles) Mount Sharp (Aeolis Mons) that sits in the center of the Gale Crater.
One thing that Major noted about the picture he assembled is the way the cylindrical RUHF antenna and the bit of the RTG that is visible in the lower center seem to form a “toothy (if slightly dusty) grin”. But, as he stated:
…with almost 21 Earth-months on Mars and lots of discoveries already under her robot belt, Curiosity (and her team) certainly have plenty to smile about!
And the best is likely to still be coming. As we speak, Curiosity is making its way towards Mount Sharp and is expected to arrive there sometime in August. As the primary goal in its mission, Curiosity set off for this destination back in June after spending months studying Glenelg area. She is expected to arrive at the foot of the mountain in August, where she will begin drilling in an effort to study the mountain’s vast caches of minerals – which could potentially support a habitable environment.
If Curiosity does find evidence of organic molecules in this cache, it will be one of the greatest scientific finds ever made, comparable only to the discovery of hominid remains in the Olduvai Gorge, or the first recorded discovery of dinosaur remains. For not only will we have definitive proof that life once existed on Mars, we will know with some certainly that it may again someday…
Stay tuned for more news from the Red Planet. And in the meantime, keep on trucking Curiosity!
In yet another impressive feat from Elon Musk’s private space company, the Falcon 9 Reusable Rocket completed it’s second test on Friday April 2nd, 2014. In this latest test of the reusable rocket system, the Falcon 9 effectively quadrupled its height from its last test. Having reached 250 meters during its last test flight, the rocket now reached a full kilometer and then descended safely back to Earth and achieving a soft landing.
This comes just two weeks after SpaceX launched one of its Falcon 9’s on a supply mission to the ISS, which included the soft landing of its stage one rocket. Unfortunately, high sea waves prevented a boat from meeting the rocket on its ocean-based pad. And so, the rocket landed in the ocean, hovering for a few seconds before toppling into the sea. Still, the fact that the rocket was able to make it back to just above sea level was good news, and confirms that SpaceX is that much closer to the dream of reusability.
In the coming months, SpaceX plans to conduct more tests. In addition to reaching higher altitudes, they will also be testing the rocket’s retractable landing legs, and working more with unpowered guidance. According to the description that came with the recently-released video of the 1000m test:
F9R test flights in New Mexico will allow us to test at higher altitudes than we are permitted for at our test site in Texas, to do more with unpowered guidance and to prove out landing cases that are more-flight like.
This is also good news for NASA, which officially announced the cessation of cooperation with the Russian Federal Space Agency in early April. While their inability to rely on Russian Soyuz rockets to send astronauts into orbit (and bring them home) has allowed NASA to apply greater pressure on the federal government to fund its Reusable Launch Vehicle (RLV) system. However, Russian Deputy Prime Minister Dmitry Rogozin had a more mocking suggestion.
After initially joking that American astronauts would be left stranded on the ISS, he also recommended that NASA try using a trampoline to reach orbit. The joke was naturally irrelevant, since day-to-day operations involving the ISS are not going to be affected by these sanctions. Still, the inability to rely on Russian Soyuz’s in the near future will mean that US satellites – which are used for everything from GPS to spying – will be undeployable for the time being.
It also means that orbit conducted in Low-Earth Orbit will be complicated. As such, a reusable rocket system, be it NASA’s own or an external contractor’s (in this case, SpaceX) will give the US sanctions against Russia additional weight. It will also ensure that the dream of cost-effective space travel, which is intrinsic to everything from colonizing the Moon and Mars to establishing a Space Elevator and asteroid mining, will be become a reality in the not-too-distant future.
The sky is no longer the limit, people! And be sure to enjoy this video of the F9R 1000 meter test flight.
A little over two years ago, a tiny piece of code was introduced to the internet that contained a bug. This bug was known as Heartbleed, and in the two years it has taken for the world to recognize its existence, it has caused quite a few headaches. In addition to allowing cybercriminals to steal passwords and usernames from Yahoo, it has also allowed people to steal from online bank accounts, infiltrate governments institutions (such as Revenue Canada), and generally undermine confidence in the internet.
What’s more, in an age of cyberwarfare and domestic surveillance, its appearance would give conspiracy theorists a field day. And since it was first disclosed a month to the day ago, some rather interesting theories as to how the NSA and China have been exploiting this to spy on people have surfaced. But more on that later. First off, some explanation as to what Heartbleed is, where it came from, and how people can protect themselves from it, seems in order.
First off, Heartbleed is not a virus or a type of malware in the traditional sense, though it can be exploited by malware and cybercriminals to achieve similar results. Basically, it is a security bug or programming error in popular versions of OpenSSL, a software code that encrypts and protects the privacy of your password, banking information and any other sensitive data you provide in the course of checking your email or doing a little online banking.
Though it was only made public a month ago, the origins of the bug go back just over two years – to New Year’s Eve 2011, to be exact. It was at this time that Stephen Henson, one of the collaborators on the OpenSSL Project, received the code from Robin Seggelmann – a respected academic who’s an expert in internet protocols. Henson reviewed the code – an update for the OpenSSL internet security protocol — and by the time he and his colleagues were ringing in the New Year, he had added it to a software repository used by sites across the web.
What’s interesting about the bug, which is named for the “heartbeat” part of the code that it affects, is that it is not a virus or piece of malware in the traditional sense. What it does is allow people the ability to read the memory of systems that are protected by the bug-affected code, which accounts for two-thirds of the internet. That way, cybercriminals can get the keys they need to decode and read the encrypted data they want.
The bug was independently discovered recently by Codenomicon – a Finnish web security firm – and Google Security researcher Neel Mehta. Since information about its discovery was disclosed on April 7th, 2014, The official name for the vulnerability is CVE-2014-0160.it is estimated that some 17 percent (around half a million) of the Internet’s secure web servers that were certified by trusted authorities have been made vulnerable.
Several institutions have also come forward in that time to declare that they were subject to attack. For instance, The Canada Revenue Agency that they were accessed through the exploit of the bug during a 6-hour period on April 8th and reported the theft of Social Insurance Numbers belonging to 900 taxpayers. When the attack was discovered, the agency shut down its web site and extended the taxpayer filing deadline from April 30 to May 5.
The agency also said it would provide anyone affected with credit protection services at no cost, and it appears that the guilty parties were apprehended. This was announced on April 16, when the RCMP claimed that they had charged an engineering student in relation to the theft with “unauthorized use of a computer” and “mischief in relation to data”. In another incident, the UK parenting site Mumsnet had several user accounts hijacked, and its CEO was impersonated.
Another consequence of the bug is the impetus it has given to conspiracy theorists who believe it may be part of a government-sanctioned ploy. Given recent revelations about the NSA’s extensive efforts to eavesdrop on internet activity and engage in cyberwarfare, this is hardly a surprise. Nor would it be the first time, as anyone who recalls the case made for the NIST SP800-90 Dual Ec Prng program – a pseudorandom number generator is used extensively in cryptography – acting as a “backdoor” for the NSA to exploit.
In that, and this latest bout of speculation, it is believed that the vulnerability in the encryption itself may have been intentionally created to allow spy agencies to steal the private keys that vulnerable web sites use to encrypt your traffic to them. And cracking SSL to decrypt internet traffic has long been on the NSA’s wish list. Last September, the Guardian reported that the NSA and Britain’s GCHQ had “successfully cracked” much of the online encryption we rely on to secure email and other sensitive transactions and data.
According to documents the paper obtained from Snowden, GCHQ had specifically been working to develop ways into the encrypted traffic of Google, Yahoo, Facebook, and Hotmail to decrypt traffic in near-real time; and in 2010, there was documentation that suggested that they might have succeeded. Although this was two years before the Heartbleed vulnerability existed, it does serve to highlight the agency’s efforts to get at encrypted traffic.
For some time now, security experts have speculated about whether the NSA cracked SSL communications; and if so, how the agency might have accomplished the feat. But now, the existence of Heartbleed raises the possibility that in some cases, the NSA might not have needed to crack SSL at all. Instead, it’s possible the agency simply used the vulnerability to obtain the private keys of web-based companies to decrypt their traffic.
Though security vulnerabilities come and go, this one is deemed catastrophic because it’s at the core of SSL, the encryption protocol trusted by so many to protect their data. And beyond abuse by government sources, the bug is also worrisome because it could possibly be used by hackers to steal usernames and passwords for sensitive services like banking, ecommerce, and email. In short, it empowers individual troublemakers everywhere by ensuring that the locks on our information can be exploited by anyone who knows how to do it.
Matt Blaze, a cryptographer and computer security professor at the University of Pennsylvania, claims that “It really is the worst and most widespread vulnerability in SSL that has come out.” The Electronic Frontier Foundation, Ars Technica, and Bruce Schneier all deemed the Heartbleed bug “catastrophic”, and Forbes cybersecurity columnist Joseph Steinberg event went as far as to say that:
Some might argue that [Heartbleed] is the worst vulnerability found (at least in terms of its potential impact) since commercial traffic began to flow on the Internet.
Regardless, Heartbleed does point to a much larger problem with the design of the internet. Some of its most important pieces are controlled by just a handful of people, many of whom aren’t paid well — or aren’t paid at all. In short, Heartbleed has shown that more oversight is needed to protect the internet’s underlying infrastructure. And the sad truth is that open source software — which underpins vast swathes of the net — has a serious sustainability problem.
Another problem is money, in that important projects just aren’t getting enough of it. Whereas well-known projects such as Linux, Mozilla, and the Apache web server enjoy hundreds of millions of dollars in annual funding, projects like the OpenSSL Software Foundation – which are forced to raise money for the project’s software development – have never raised more than $1 million in a year. To top it all off, there are issues when it comes to the open source ecosystem itself.
Typically, projects start when developers need to fix a particular problem; and when they open source their solution, it’s instantly available to everyone. If the problem they address is common, the software can become wildly popular overnight. As a result, some projects never get the full attention from developers they deserve. Steve Marquess, one of the OpenSSL foundation’s partners, believes that part of the problem is that whereas people can see and touch their web browsers and Linux, they are out of touch with the cryptographic library.
In the end, the only real solutions is in informing the public. Since internet security affects us all, and the processes by which we secure our information is entrusted to too few hands, then the immediate solution is to widen the scope of inquiry and involvement. It also wouldn’t hurt to commit additional resources to the process of monitoring and securing the web, thereby ensuring that spy agencies and private individuals are not exercising too much or control over it, or able to do clandestine things with it.
In the meantime, the researchers from Codenomicon have set up a website with more detailed information. Click here to access it and see what you can do to protect yourself.
Scientists have come up with the best computer model to date of the universe, one which maps the evolution of the cosmos in unprecedented detail. Known as Illustris, this virtual cosmos – which was created by U.S., English and German researchers using a network of supercomputers – includes details never before achieved in a simulation. All told, the numerical-based model covers the 13-billion-year evolution of the universe, beginning just 12 million years after the Big Bang took place.
Given all the recent breakthroughs in physics and cosmology, this ultra-detailed virtual model should come as no surprise. For example, this past April, scientists made not only made the first-ever observation of gravitational waves, they also processed data that is believed to be the first real indication of the existence of Dark Matter. In addition, the ESA’s Planck mission released the most detailed thermal imaging map of the universe last year that placed an accurate date on the universe’s age and confirmed the validity of the Big Bang Theory.
Beyond Japan, solar power is considered the of front runner of alternative energy, at least until s fusion power comes of age. But Until such time as a fusion reaction can be triggered that produces substantially more energy than is required to initiate it, solar will remain the only

And all of this has associated costs, not the least of which is in damages, insurance costs, and health care expenses.
