A Kinder, Gentler Internet: California’s “Erase Button”

cyber bullyingIn the early nineties, the internet was greeted with immense optimism and anticipation. Scarcely a week went by without some major personality – Al Gore and Bill Gates come to mind – championing its development, saying it would bring the world together and lead to “the information age”. After just a few years, these predictions were being mocked by just about everyone on the planet who had access.

Rehtaeh_ParsonsYes, despite all that has been made possible by the internet, the heady optimism that was present in those early days seem horribly naive by today’s standards. In addition to making virtually any database accessible to anyone, the world wide web has also enabled child pornographers, hate speech, conspiracy theorists and misinformation like never before.

What’s more, a person’s online presence opens them to new means of identity theft, cyberbullying, and all kinds of trolling and harassment. Who can forget the cases of Amanda Todd or Rethaeh (Heather) Parsons? Two young women who committed suicide due to relentless and disgusting bullying that was able to take place because there simply was no way to stop it all.

amanda_toddsuicide.jpeg.size.xxlarge.letterboxAnd with the ever expanding online presence of children and youths on the internet, and little to no controls to monitor their behavior, there are many campaigns out there that hope to reign in the offenders and protect the users. But there are those who have gone a step further, seeking to put in place comprehensive safeguards so that trollish behavior and hurtful comments can be stopped before it becomes a permanent part of the digital stream.

One such person is California Governor Jerry Brown, who recently signed a bill into law that requires all websites to provide an online “erase button” for anyone under 18 years of age. The stated purpose of the law is to help protect teens from bullying, embarrassment and harm to job and college applications from online posts they later regret. The law, which is designated SB568, was officially passed on Sept. 23rd and will go into effect Jan 1st, 2015.

kid-laptop-156577609_610x406Common Sense Media, a San Francisco based non-profit organization that advocates child safety and family issues, was a major supporter of the bill. In a recent interview, CEO James Steyer explained the logic behind it and how it will benefit youths:

Kids and teens frequently self-reveal before they self-reflect. In today’s digital age, mistakes can stay with and haunt kids for their entire life. This bill is a big step forward for privacy rights, especially since California has more tech companies than any other state.

The law is not without merit, as a 2012 Kaplan survey conducted on college admissions counselors shows. In that study, nearly a quarter of the counselors interviewed said they checked applicants’ social profiles as part of the admission process. Of those counselors, 35% said what they found – i.e. vulgarities, alcohol consumption, “illegal activities” – negatively affected their applicants’ admissions chances.

smartphoneteensBut of course, the bill has its share of opponents as well. Of those who voted against it, concerns that the law will burden websites with developing policies for different states appeared to be paramount. Naturally, those who support the bill hope it will spread, thus creating a uniform law that will remove the need to monitor the internet on a state-by-state basis.

At present, major social media sites such as Facebook, Twitter, Instagram and Vine already allow users of any age to delete their posts, photos and comments. California’s “eraser button” law requires that all websites with users in the state follow this policy from now on. And given the presence of Silicon Valley and the fact that California has one of the highest per capita usages of the internet in the country, other states are sure to follow.

facebook-privacyThe new law also prohibits youth-oriented websites or those that know they have users who are minors from advertising products that are illegal to underage kids, such as guns, alcohol and tobacco. Little wonder then why it was also supported by organizations like Children NOW, Crime Victims United, the Child Abuse Prevention Center and the California Partnership to End Domestic Violence.

In addition to being a legal precedent, this new law represents a culmination of special interests and concerns that have been growing in size and intensity since the internet was first unveiled. And given the recent rise in parental concerns over cyberbullying and teen suicides connected to online harassment, its hardly surprising that something of this nature was passed.

Ending HIV: Foot Cream Kills HIV Cells!

HIV-budding-ColorThe fight to end HIV has been long and ongoing. But in recent years, researchers have made some incredible breakthroughs in terms of treatment and vaccines. Well as it turns out, the fight may be getting a punch in the arm from a most unlikely source – an anti-fungal foot cream! Yes, not only does this common drug kill HIV, it is even more effective than some of today’s most cutting-edge drugs.

In a study performed at Rutgers New Jersey Medical School, the drug Ciclopirox was shown to completely eradicate infectious HIV when applied to cell cultures of the virus. But what was even more impressive was the fact that the virus didn’t bounce back when the drug was withheld. This means that, unlike most anti0viral drugs, it may not require a lifetime of use to keep HIV at bay.

ciclopiroxThe same group of researchers had previously shown that Ciclopirox – which was approved by the FDA and Europe’s EMA to treat foot fungus – inhibits the expression of HIV genes. Now they have found that it also blocks the essential function of the mitochondria, which results in the reactivation of the cell’s suicide pathway, all while sparing surrounding healthy cells.

This is key since one of the worst aspects of HIV – one that makes it particularly persistent, even in the face of strong antiviral treatments – is its ability to disable a cell’s altruistic suicide pathway. This “self-destruct protocol” is typically activated when a cell is damaged or infected. With the introduction of Ciclopirox, these cells are tricked into pulling a double negative, disabling the disabling of the suicide pathway.

HIVNaturally, the cream will have to be tested on humans before its efficacy as a topical HIV treatment can be tested. However, the fact that it’s already been deemed safe for one type of human use could make the regulatory process faster than usual. In fact, the researchers have noted that another FDA-approved drug now thought to help subdue HIV (called Deferiprone) skipped animal studies and went straight to human trials in South Africa.

Naturally, the Rutgers team hopes they too can go directly from their culture studies to human trials, and that the case involving Deferiprone will pave the way for a more streamlined testing process. This is likely, seeing as how there have been many breakthroughs in recent months and everyone – from researchers to patients to medical authorities – want to make treatments available as soon as possible.

News From Space: Big Bang Vs. Black Hole

big bang_blackholeFor decades, the Big Bang Theory has remained the accepted theory of how the universe came to be, beating out challengers like the Steady State Theory. However, many unresolved issues remain with this theory, the most notable of which is the question of what could have existed prior to the big bang. Because of this, scientists have been looking for way to refine the theory.

Luckily, a group of theoretical physicists from the Perimeter Institute (PI) for Theoretical Physics in Waterloo, Ontario have announced a new interpretation on how the universe came to be. Essentially, they postulate that the birth of the universe could have happened after a four-dimensional star collapsed into a black hole and began ejecting debris.

big_bangThis represents a big revision of the current theory, which is that universe grew from an infinitely dense point or singularity. But as to what was there before that remain unknown, and is one of a few limitations of the Big Bang. In addition, it’s hard to predict why it would have produced a universe that has an almost uniform temperature, because the age of our universe (about 13.8 billion years) does not give enough time to reach a temperature equilibrium.

Most cosmologists say the universe must have been expanding faster than the speed of light for this to happen. But according to Niayesh Afshordi, an astrophysicist with PI who co-authored the study, even that theory has problems:

For all physicists know, dragons could have come flying out of the singularity. The Big Bang was so chaotic, it’s not clear there would have been even a small homogenous patch for inflation to start working on.

black_holeThe model Afshordi and her colleagues are proposing is basically a three-dimensional universe floating as a membrane (or brane) in a “bulk universe” that has four dimensions. If this “bulk universe” has four-dimensional stars, these stars could go through the same life cycles as the three-dimensional ones we are familiar with. The most massive ones would explode as supernovae, shed their skin and have the innermost parts collapse as a black hole.

The 4-D black hole would then have an “event horizon”, the boundary between the inside and the outside of a black hole. In a 3-D universe, an event horizon appears as a two-dimensional surface; but in a 4-D universe, the event horizon would be a 3-D object called a hypersphere. And when this 4-D star blows apart, the leftover material would create a 3-D brane surrounding a 3-D event horizon, and then expand.

planck-attnotated-580x372To simplify it a little, they are postulating that the expansion of the universe was triggered by the motion of the universe through a higher-dimensional reality. While it may sound complicated, the theory does explain how the universe continues to expand and is indeed accelerating. Whereas previous theories have credited a mysterious invisible force known as “dark energy” with this, this new theory claims it is the result of the 3-D brane’s growth.

However, there is one limitation to this theory which has to do with the nearly uniform temperature of the universe. While the model does explain how this could be, the ESA’s Planck telesceop recently mapped out the universe and discovered small temperature variations in the cosmic microwave background (CBM). These patches were believed to be leftovers of the universe’s beginnings, which were a further indication that the Big Bang model holds true.

big_bang1The PI team’s own CBM readings differ from this highly accurate survey by about four percent, so now they too are going back to the table and looking to refine their theory. How ironic! However, the IP team still feel the model has worth. While the Planck observations show that inflation is happening, they do not show why the inflation is happening.

Needless to say, we are nowhere near to resolving how the universe came to be, at least not in a way that resolves all the theoretical issues. But that’s the things about the Big Bang – it’s the scientific equivalent of a Hydra. No matter how many times people attempt to discredit it, it always comes back to reassert its dominance!

More News in Quantum Computing!

quantum-computers-The-Next-GenerationRecently, a team of researchers at the University of Rochester conducted an experiment where they managed to suspend a nano-sized diamond in free space with a laser. The purpose of the experiment was to measure the amount of light emitted from the diamond, but had the added bonus of demonstrating applications that could be useful in the field of quantum computing.

For those unfamiliar with the concept, quantum computing differs from conventional computing since it does not rely on sending information via a series of particles (electrons) through one-way channels. Instead, quantum computing relies on the process of beaming the states of particles (i.e. a photons quantum properties) from one location to the next.

nanodiamondSince this process occurs faster than the speed of light (as no movement takes place) and qubits (quantum bits) have the ability to be in more than one state simultaneously, computations done using this model would be exponentially faster. But despite many advancements made in recent years, the field remains largely theoretical and elusive.

To conduct their experiment, the researchers focused a laser into a 25 cm (10 inch) chamber and then sprayed an aerosol containing dissolved nanodiamonds inside. These nanodiamonds were attracted to the laser in a technique known as “laser trapping”, until a single particle was isolated and made to levitate. Once the tiny gem was levitating in free space, the researchers used another laser to make defects within the diamond emit light at given frequencies.

nanodiamond1This process is known as photoluminescence – a form light emission that is caused by defects in the tiny diamond that allows for the absorptions of photons. When the system is excited, it changes the spin; and when the it relaxes after the change, other photons are emitted. This occurs because nitrogen atoms replace some of the carbon atoms in the diamond. Once the nitrogen is nested in the diamond’s atomic structure, it is possible to excite electrons with a laser.

According to the researchers, this photoluminescence process has the potential to excite the system and cause what is known as Bohr spin quantum jumps, which are changes in spin configuration of the internal defect. This occurs because nitrogen atoms replace some of the carbon atoms in the diamond. Once the nitrogen is nested in the diamond’s atomic structure, it is possible to excite electrons with a laser.

????????????????????In addition, the potential also exists to turn the nanodiamond into an optomechanical resonator. According to Nick Vamivakas, an assistant professor of optics at the University of Rochester, these are structures in which the vibrations of the system can be controlled by light. Optomechanical resonators have the potential to be used as incredibly precise sensors, which could lead to uses in microchips.

In addition, these resonator systems have the potential to create Schrödinger Cat states, which are typically not found in microscopic objects. As anyone who’ familiar with Futurama or Big Bang Theory may recall, this refers to the thought experiment where a cat is inside a box with poison, and until someone opens the box and determines its whereabouts, the cat could be considered simultaneously both alive and dead.

^Being able to stimulate matter so that it can exist in more than one state at any given time is not only revolutionary, it is a clear step towards the creation of machines that exploit this principle to perform computations. According to Nick Vamivakas, an assistant professor of optics at the University of Rochester, explained:

Cat or cat-like states contradict our everyday experiences since we do not see common things in quantum states. The question is: where is this boundary between microscopic and macroscopic? By generating quantum states of larger and larger objects, we can hone in on a boundary … if there is one.

Naturally, the Rochester team is still a long way from achieving their big breakthrough, and Vamivakas himself admits that he does not know how far away a quantum computing truly is. In terms of this latest experiment, the team still needs to cool the crystal better, which they are hoping can be achieved with a few technical improvements. And then they hope to find a better way of running the experiment than spraying nanodiamond dust into a tube.

In the meantime, check out this video of the experiment. It promises to be “illuminating” (sorry!):

GOT Fanfilm: A Tale of Benjen Stark

A-taleofBenjenStarkThough season four may still be many months away, some in the fan community have bravely stepped up to make sure the die hards of Game Of Thrones get a dose to tide them over. In this case, the fans in question are the good folks behind The Von Wong and Five Knights Productions, who have created A Tale of Benjen Stark, a short fanfilm that addresses a hole in the series’ story.

Basically, the film explores the question of what happened to Ben Stark, Lord Ned Stark’s brother and a man of the Night’s Watch. As fans of the book and TV series may recall, Benjen set out north of the Wall in the first installment, seeking to find what was behind the reported deaths of several Wildlings and the disappearance of his brothers. After setting out, he was never heard from again, and only passing clues were given as to his fate.

A-taleofBenjenStark1In A Tale of Benjen Stark, his adventure north of the Wall is chronicled, as is the discovery he makes that is later uncovered by Jon Snow. As expected, the production values are not as good as the show itself, and it kind of borders on a zombie B movie, but it still manages to address something that was never fully resolved in the story.

And based on the success of this movie, the production team has indicated that they are open to making a second installment. If all goes well, they should be able to wrap up Benjen’s entire story arc, culminating in the little “gift” he left behind for his brother’s to find. Enjoy!

Repitching an Old Idea: The Council of Muraqaba

world_religionsHey folks! A lot of things have got me thinking about another old idea that I think needs to be updated and brought forward. This one comes from many years back, roughly 2007, when I was working on the series of short stories that make up my Legacies series. As one of several ideas I was working with back then, it kind of fell by the wayside as I busied myself with writing the others – Flight of the Icarus, Eyes in the Dark, Turncoats, Vega Rising.

Eventually, as with many ideas us indie writers come up with, it lost my interest after lingering so long in my Inbox. But after a few conversations with respected colleagues, I found myself thinking about it again and looking to update it, add a new spin, and just generally give it another try. The story, in its updated version, is called The Council of Muraqaba, and it concerns humanity’s efforts to create a universal religion in the future.

world_religions_distWhen I first came up with the idea for a universal faith as part of my Legacies universe, I was still in my Frank Herbert phase and borrowed many crumbs off his table. His own notes in Dune about the Orange Catholic Bible and the Commission of Ecumenical Translators that created it really inspired me, and it put me in mind of the World Religions class I took in high school, which just happened to be one of my favorite subjects.

In 2007, the short story that was to feature the attempts to create this religion was more of an original idea, at to me. I envisioned a world where the council behind the religion’s creation established a permanent seat where matters of interfaith exchanges could take place, and where research into what made them all tick could be done and universal principles uncovered.

world_religions_popThis seemed like a timely idea to me given just how controversial, central, and daunting the issue of faith continues to be in our world today. Between people who demand that others conform to their religion to those who condemn religion of any kind, and from those who use it justify violence and persecution to those who blame it for the problems of entire regions of the world (i.e. Africa, the Middle East and Islamophobia), it’s almost inescapable.

Because of this, and because of the way humanity has a hard time outgrowing old habits, I figured a story that dealt with humanity’s continued difficulties with religion and sectarian differences should be included in my Legacies bundle. But as I said, I’ve been updating the idea a bit thanks to some conversations with friends which raised some poignant issues about the future, and thanks to some research about what the future is likely to hold…

gliese-581.jpgWhat I am envisioning now is a world where a group of mystic settlers originally established a colony on Gliese 581 d – aka. Muraqaba – in the hopes of creating a community where traditional faiths could still be practiced, free from the fear of ongoing progress and how it was leading many to conclude that religion was obsolete. Named after the Sufi practice of meditation, they sought to live in peace and practice freely, and were on guard against what they saw as “needless augmentation”.

In time, this community expanded and became dedicated to finding a way to bring all faiths together and finding common ground not just between religions but between faith and science itself, something which still eluded people in this age. Eventually, this led to the creation of the Council of Muraqaba, a permanent institution where scholars and religious authorities could meet, discuss, and network with people in the universe at large to iron out matters of spirituality.

matrix_cyberspaceIronically, the Council became a hub for some of the most advanced interstellar learning and education since people who were light years away from each other could communicate using a quantum array that allowed FTL communications to take place. The experience of this is central to the story, as it provides a sort of mystic mental sharing that is akin to a spiritual connection, emotions and thoughts shared instantaneously between people.

And of course, there will be a twist as a regular day at the Council turns into something sinister. Just because the local inhabitants have succeeded in creating a dialogue with the universe at large doesn’t mean that everyone is interesting in what they have to say. And some people are concerned that all this “common ground” stuff is eroding the things that make their faith special and want it to end.

And some… some are interested in what the Council has to say for reasons that go far beyond matters of faith! Be sure to check it out, as I think this story just might be one of my more inspired pieces of writing. And my thanks once again for Khaalidah for turning on the light in my head. There’s a reason I call you “Lady Inspiration” you know 😉

Judgement Day Update: Artificial Muscles for Robots

artificial-muscle-1It’s a science fiction staple, the android or humanoid robot opens up its insides to reveal a network of gears or brightly-lit cables running underneath. However, as the science behind making androids improves, we are moving farther and farther away from this sci-fi cliche. In fact, thanks to recent advancements, robots in the future may look a lot like us when you strip away their outer layers.

It’s what is known as biomimetics, the science of creating technology that mimics biology. And the latest breakthrough in this field comes from National University of Singapore’s Faculty of Engineering where researchers have developed the world’s first “robotic” muscle. Much like the real thing, this artificial tissue extends to five times its original length, has the potential to lift 80 times its own weight.

???????????????????????In addition to being a first in robotics, this new development is exciting because it resolves a central problem that has plagued robots since their inception. In the 1960s, John W. Campbell Jr, editor of Analog Science Fiction magazine, pointed out this problem when he outlined a scenario where a man is chased across rough country by a mad scientist’s horde of killer robots.

In this scenario, the various models that were chasing the man were stymied by obstacles that the he could easily overcome, such as sinking in mud, jumping over logs, getting around rocks, or tangled up in bushes. In the end, the only robots that were capable of keeping up with him were so light and underpowered that he was able to tear them apart with his bare hands.

robot_muscleThis is a far cry from another science fiction staple, the one which presents robots as powerful automatons that can bend steel girders and carry out immense feats of strength. While some robots certainly can do this, they are extremely heavy and use hydraulics for the heavy lifting. Pound for pound, they’re actually very weak compared to a human, being capable of lifting only half their weight.

Another problem is the fact that robots using gears and motors, pneumatics, or hydraulics lack fine control. They tend to move in jerky motions and have to pause between each move, giving rise to a form of motion that we like to call “the robot”. Basically, it is very difficult to make a robot that is capable of delicate, smooth movements, the kind humans and animals take for granted.

kenshiroFor some time now, scientists and researchers have been looking to biomimetics to achieve the long sought-after dream of smaller, stronger robots that are capable of more refined movements. And taken in tandem with other development – such as the Kenshiro robot developed by roboticists at the University of Tokyo – that time might finally be here.

Developed by a four-person team led by Dr. Adrian Koh – from the NUS Engineering Science Program and Department of Civil and Environmental Engineering – the new artificial muscle is an example of an electroactive polymer. Basically, this is a combination dielectric elastomer and rubber that changes shape when stimulated by an electric field. In this respect, the artificial muscle is much like an organic one, using electrical stimulus to trigger movement.

 

robot-arm-wrestling-03-20-09Robots using artificial muscles would be a far cry from clanking mechanical men. They would be much more lifelike, capable of facial expression and precise, graceful movements. They would also have superhuman strength, yet weigh the same as a person. In addition, the polymer used to fabricate the muscles may have more general applications in machines, such as cranes.

An added bonus of the polymer is that is can convert and store energy, which means it’s possible to design robots that power themselves after charging for only minutes. In a statement released by his department, Dr. Koh highlighted the benefits of the design and what it is capable of doing:

Our novel muscles are not just strong and responsive. Their movements produce a by-product – energy. As the muscles contract and expand, they are capable of converting mechanical energy into electrical energy. Due to the nature of this material, it is capable of packing a large amount of energy in a small package. We calculated that if one were to build an electrical generator from these soft materials, a 10 kg (22 lb) system is capable of producing the same amount of energy of a one-ton electrical turbine.

AI_robotDr. Koh also indicated that robots equipped with these types of muscles “will be able to function in a more human-like manner – and outperform humans in strength.” Theoretically, such polymer-based tissues could extend to ten times their original length and lift up to 500 times its own weight, though the current version isn’t anywhere near that limit just yet.

In the meantime, Dr Koh and his team have applied for a patent for the artificial muscle and are continuing work on it. They predict that within five years they could have a robot arm that is half the size and weight of a human arm, yet could win an arm wrestling match. And the applications are limitless, ranging from robotic servants to search and rescue bots and heavy robot laborers. And let’s not forget that cybernetic arms that boast that kind of increased strength are also likely to become a popular prosthetic and enhancement item.

And for those who are naturally afraid of a future where super-human robots that have the strength to tear us limb from limb are walking among us, let me remind you that we still have Asimov’s “Three Laws of Robotics” to fall back on. Never mind what happened in the terrible movie adaptation, those laws are incontrovertible and will work… I hope!

BIG News From Space: Alien Matter Found?

Alien OrganismsIts been an exciting 48 hours for the scientific community. It began when a team of British scientists floated a balloon up into the stratosphere, more than 25 km (16 miles) up, and when it came down they found it was carrying tiny organisms. The scientists claimed that there is no way that such organisms could have come from Earth and found their way into the stratosphere, so they must have come from space.

Specifically, they must have come from a comet, given their particular characteristics, and they could even be evidence that all life on Earth really did originate in the stars. This theory is known as Exogenesis (or Panspermia), and contends that this is how organisms are spread throughout the universe – spawning in certain environments, but flourishing on worlds where they are deposited and conditions are just right.

Alien Organisms1According to Professor Milton Wainwright of the Department of Molecular Biology and Biotechnology at the University of Sheffield, they are “about 95 percent convinced” of that fact, though he admits that it’s hard to be absolutely certainty. But apart from the height of the organisms, which would make it hard to imagine them being from Earth, Wainwright and his team also noted that they bear no physical signs of ever being earthbound.

As Wainwright said in the course of announcing the team’s findings:

There is no known mechanism by which these life forms can achieve that height. As far as we can tell from known physics, they must be incoming. The particles are very clean. They don’t have any dust attached to them, which again suggests they’re not coming to earth. Similarly, cosmic dust isn’t stuck to them, so we think they came from an aquatic environment, and the most obvious aquatic environment in space is a comet.

In addition, the science team ruled out the possibility that the particles were originally from Earth and were blasted into the stratosphere by a volcano, noting that it’s been too long since the last volcanic eruption on Earth for the particles to have maintained such a height. So the tentative conclusion remains, that the organisms were placed in orbit by a passing comet.

DNA-1What’s even more exciting is the prospect that the organisms, though they are all likely dead at this point, are likely to contain alien DNA. If this proves to be true, it could further the idea that life on Earth may have had its beginnings in cosmos. Next month, the team plans to try the balloon test again to see if they can both confirm their results and find new organisms in upcoming meteor shower tied to Halley’s Comet.

Exciting prospects indeed. But almost immediately after the announcement been made, dissenting voices began to come forward to poke holes in the team’s theory. One such person is Phil Plait, an astronomer who upon reading the findings in the Journal of Cosmology, raised a number of concerns and criticisms about the team’s research.

First, Plait notes, one member of the research team, Chandra Wickramasinghe, has claimed numerous times that he’s discovered diatoms – a type of phytoplankton found in meteorites – and this particular paper also includes similar diatom findings. Wickramsinghe also, according to Plait, has a long history of making dubious claims about extraterrestrial life, using less-than-thorough research.

PanspermiaPlait also noted that the Journal of Cosmology, where the paper was published, has a less-than-spotless reputation. In the past, the quality of peer review at the journal has been questioned, and they have also been accused of promoting fringe and speculative viewpoints on astrobiology, astrophysics, and quantum physics. Of particular concern is the journal’s apparent bias that the theory of Panspermia is established fact, which remains a theory.

But as to the scientific findings themselves, there’s the question of whether the diatom really came from space or became attached to the balloon as it transited from the surface into orbit. While the team claims that precautions were taken and the sample was too clean, extended testing may prove this conclusion to be wrong, and possibly premature.

Second, Plait disputes the conclusion that the diatom could not have been put up in the atmosphere by a volcanic eruption. Specifically, he noted that the researchers didn’t seem to take into account things like turbulence in the stratosphere that could have kept objects previously hurled up there by volcanoes floating around for quite some time.

panspermia1Then there’s the claim that evidence points that the organisms came from a comet. The fact that it was “remarkably clean and free of soil or other solid material,” works against this conclusion, according to Plait. If indeed it came embedded in rock, there would surely be samples of soil, dust, ice or minerals attached to it, as these are things commonly found in a comet.

And finally, there’s the theory the researchers developed that these organisms are evidence that life actually began somewhere in space, then came to Earth. While Panspermia is a good theory, Plait claims that the scientists are going about arguing it in a way that is not strictly scientific:

Panspermia is worth investigating, but it’s worth investigating correctly. Outrageous claims on thin evidence with huge conclusion-jumping don’t comprise the best way to do it. Stories like this one are sexy and sure bait for an unskeptical media, of course. But at the very least they don’t help the public understand science and the scientific process, and I know some scientists take an even dimmer view of it.

But of course, the announcement was just made and there’s still plenty of checking to do. In the meantime, we can all certainly speculate, and I would like to hear from the people out there. What do you think? Does this discovery constitute a scientific breakthrough, or is it an elaborate hoax or a case of eager scientists jumping to conclusions?

Mars_Earth_Comparison-580x356And let’s not forget, this announcement comes not long after Professor Steven Benner’s similar announcement that new evidence connects the origin of life on Earth to life on Mars. No reason why Exogenesis and the Martian hypothesis can’t coexist now is there?

Digital Eyewear Through the Ages

google_glassesGiven the sensation created by the recent release of Google Glass – a timely invention that calls to mind everything from 80’s cyberpunk to speculations about our cybernetic, transhuman future – a lot of attention has been focused lately on personalities like Steve Mann, Mark Spritzer, and the history of wearable computers.

For decades now, visionaries and futurists have been working towards a day when all personal computers are portable and blend seamlessly into our daily lives. And with countless imitators coming forward to develop their own variants and hate crimes being committed against users, it seems like portable/integrated machinery is destined to become an issue no one will be able to ignore.

And so I thought it was high time for a little retrospective, a look back at the history of eyewear computers and digital devices and see how far it has come. From its humble beginnings with bulky backpacks and large, head-mounted displays, to the current age of small fixtures that can be worn as easily as glasses, things certainly have changed. And the future is likely to get even more fascinating, weird, and a little bit scary!

Sword of Damocles (1968):
swordofdamoclesDeveloped by Ivan Sutherland and his student Bob Sprouli at the University of Utah in 1968, the Sword of Damocles was the world’s first heads-up mounted display. It consisted of a headband with a pair of small cathode-ray tubes attached to the end of a large instrumented mechanical arm through which head position and orientation were determined.

Hand positions were sensed via a hand-held grip suspended at the end of three fishing lines whose lengths were determined by the number of rotations sensed on each of the reels. Though crude by modern standards, this breakthrough technology would become the basis for all future innovation in the field of mobile computing, virtual reality, and digital eyewear applications.

WearComp Models (1980-84):
WearComp_1_620x465Built by Steve Mann (inventor of the EyeTap and considered to be the father of wearable computers) in 1980, the WearComp1 cobbled together many devices to create visual experiences. It included an antenna to communicate wirelessly and share video. In 1981, he designed and built a backpack-mounted wearable multimedia computer with text, graphics, and multimedia capability, as well as video capability.

Wearcomp_4By 1984, the same year that Apple’s Macintosh was first shipped and the publication of William Gibson’s science fiction novel, “Neuromancer”, he released the WearComp4 model. This latest version employed clothing-based signal processing, a personal imaging system with left eye display, and separate antennas for simultaneous voice, video, and data communication.

Private Eye (1989):
Private_eye_HUDIn 1989 Reflection Technology marketed the Private Eye head-mounted display, which scanned a vertical array of LEDs across the visual field using a vibrating mirror. The monochrome screen was 1.25-inches on the diagonal, but images appear to be a 15-inch display at 18-inches distance.

EyeTap Digital Eye (1998):
EyeTap1Steve Mann is considered the father of digital eyewear and what he calls “mediated” reality. He is a professor in the department of electrical and computer engineering at the University of Toronto and an IEEE senior member, and also serves as chief scientist for the augmented reality startup, Meta. The first version of the EyeTap was produced in the 1970’s and was incredibly bulky by modern standards.

By 1998, he developed the one that is commonly seen today, mounted over one ear and in front of one side of the face. This version is worn in front of the eye, recording what is immediately in front of the viewer and superimposing the view as digital imagery. It uses a beam splitter to send the same scene to both the eye and a camera, and is tethered to a computer worn to his body in a small pack.

MicroOptical TASK-9 (2000):
MicroOptical TASK-9Founded in 1995 by Mark Spitzer, who is now a director at the Google X lab. the company produced several patented designs which were bought up by Google after the company closed in 2010. One such design was the TASK-9, a wearable computer that is attachable to a set of glasses. Years later, MicroOptical’s line of viewers remain the lightest head-up displays available on the market.

Vuzix (1997-2013):
Vuzix_m100Founded in 1997, Vuzix created the first video eyewear to support stereoscopic 3D for the PlayStation 3 and Xbox 360. Since then, Vuzix went on to create the first commercially produced pass-through augmented reality headset, the Wrap 920AR (seen at bottom). The Wrap 920AR has two VGA video displays and two cameras that work together to provide the user a view of the world which blends real world inputs and computer generated data.

vuzix-wrapOther products of note include the Wrap 1200VR, a virtual reality headset that has numerous applications – everything from gaming and recreation to medical research – and the Smart Glasses M100, a hands free display for smartphones. And since the Consumer Electronics Show of 2011, they have announced and released several heads-up AR displays that are attachable to glasses.

MyVu (2008-2012):
Founded in 1995, also by Mark Spitzer, MyVu developed several different types of wearable video display glasses before closing in 2012. The most famous was their Myvu Personal Media Viewer (pictured below), a set of display glasses that was released in 2008. These became instantly popular with the wearable computer community because they provided a cost effective and relatively easy path to a DIY, small, single eye, head-mounted display.myvu_leadIn 2010, the company followed up with the release of the Viscom digital eyewear (seen below), a device that was developed in collaboration with Spitzer’s other company, MicroOptical. This smaller, head mounted display device comes with earphones and is worn over one eye like a pair of glasses, similar to the EyeTap.

Meta Prototype (2013):
Developed by Meta, a Silicon Valley startup that is being funded with the help of a Kickstarter campaign and supported by Steve Mann, this wearable computing eyewear ultizes the latest in VR and projection technology. Unlike other display glasses, Meta’s eyewear enters 3D space and uses your hands to interact with the virtual world, combining the benefits of the Oculus Rift and those being offered by “Sixth Sense” technology.

meta_headset_front_on_610x404The Meta system includes stereoscopic 3D glasses and a 3D camera to track hand movements, similar to the portrayals of gestural control in movies like “Iron Man” and “Avatar.” In addition to display modules embedded in the lenses, the glasses include a portable projector mounted on top. This way, the user is able to both project and interact with computer simulations.

Google Glass (2013):
Google Glass_CalaDeveloped by Google X as part of their Project Glass, the Google Glass device is a wearable computer with an optical head-mounted display (OHMD) that incorporates all the major advances made in the field of wearable computing for the past forty years. These include a smartphone-like hands-free format, wireless internet connection, voice commands and a full-color augmented-reality display.

Development began in 2011 and the first prototypes were previewed to the public at the Google I/O annual conference in San Francisco in June of 2012. Though they currently do not come with fixed lenses, Google has announced its intention to partner with sunglass retailers to equip them with regular and prescription lenses. There is also talk of developing contact lenses that come with embedded display devices.

Summary:
Well, that’s the history of digital eyewear in a nutshell. And as you can see, since the late 60’s, the field has progressed by leaps and bounds. What was once a speculative and visionary pursuit has now blossomed to become a fully-fledged commercial field, with many different devices being produced for public consumption.

At this rate, who knows what the future holds? In all likelihood, the quest to make computers more portable and ergonomic will keep pace with the development of more sophisticated electronics and computer chips, miniaturization, biotechnology, nanofabrication and brain-computer interfacing.

The result will no doubt be tiny CPUs that can be implanted in the human body and integrated into our brains via neural chips and tiny electrodes. In all likelihood, we won’t even need voice commands at that point, because neuroscience will have developed a means to communicate directly to our devices via brainwaves. The age of cybernetics will have officially dawned!

Like I said… fascinating, weird, and a little bit scary!

News From Space: The Antares Rocket Launch!

antares_launch1Commercial space flight got a shot in the arm just two days ago thanks to the flawless launch of the privately developed Antares rocket from the NASA Wallops Flight Facility in Virginia. On board was the first of many Cygnus craft, a commercial unmanned cargo resupply vehicle that is now making its way to the ISS in orbit. It was a day of firsts, and signaled the beginning of a new space race.

For starters, it was the first time the launchpad in Virginia was used, not to mention the maiden flight of a Cygnus craft. But perhaps most importantly, it was the first time in a long time that supplies and equipment were bound for the International Space Station from American soil. Since its cancellation in 2011, NASA’s space program has been forced to rely on the Russians and an aging fleet of Soyuz rockets to send astronauts and supplies into orbit.

spaceX_elonmuskAnd, as already noted, it was a big day for commercial space flight, since both the Antares and the Cygnus were produced by the Orbital Sciences Corporation. For some time now, SpaceX has been leading the charge to develop rockets and spacecraft for private commercial use. Now, with NASA awarding OSC contracts to restore America’s ability to mount resupply missions, it seems they might have some competition.

The “picture perfect” blastoff took place at 10:58 a.m. EDT on the morning  of Sept. 18 from Virginia and was witnessed by a large crowd of spectators. The launch was reported as being incredibly beautiful as the rockets two stage engines spewed intensely bright flames and send out reverberations that wowed the people watching and woke people who were still asleep in the nearby community of Chincoteague.

antares_deploymentAnother historic first that bears mentioning is the fact that this latest mission happens to be the heaviest cargo load ever delivered to the ISS by a commercial vehicle. And by awarding contracts for such missions to private companies, NASA hopes to be able to free more of its budget up for long-term missions. These include exploration beyond low earth orbit, getting people back to the Moon and beyond to deep space destinations including Asteroids and Mars.

NASA Administrator Charles Bolden spoke glowingly of the launch in a statement and praised OSC for their role in making it happen:

Today marks a milestone in our new era of exploration as we expand the capability for making cargo launches to the International Space Station from American shores.  Orbital’s extraordinary efforts are helping us fulfill the promise of American innovation to maintain our nation’s leadership in space.

According to ongoing mission updates, the Cygnus spacecraft successfully unfurled its solar panels starting 1.5 minutes after separation from the second stage, which took place about 10 minutes after launch. Currently, Cygnus is traveling at 28,000 km/h (17,500 mph) and will rendezvous with the space station on Sunday, Sept. 22.

antares_launch2Once there, the cargo vessel will deliver about 590 kilograms (1,300 pounds) of cargo, including food, clothing, water, science experiments, spare parts and gear to the Expedition 37 crew. The flight, known as Orb-D1 is a demonstration mission to prove that Cygnus can conduct a complex series of maneuvers in space safely bringing it to the vicinity of the ISS.

And once the mission is complete and the supplies delivered, we can expect to be hearing about more missions like this one! Between SpaceX’s Dragon module, the Cygnus, and both companies ongoing rocket tests, space will is likely to become the new frontier where private enterprises carry out their endless dance of competition.

And of course, there are some cool videos of the launch to behold. So behold!
