News From Mars: Revelations on Radiation

mars_astronauts1As the projected date for a manned mission to the Red Planet approaches, the Mars Science Laboratory and Curiosity team continue to conduct vital research into what a human team of explorers can expect to find. Unfortunately, earlier last month, that research led to a discouraging announcement which may force NASA and a number of private companies to rethink their plans for manned missions.

Earlier in May, a number of scientists, NASA officials, private space company representatives and other members of the spaceflight community gathered in Washington D.C. for a three day meeting known as the Humans to Mars (H2M) conference. Hosted by the spaceflight advocacy group Explore Mars, the attendees met to discuss all the challenges that a 2030 manned mission would likely encounter.

mars_astronautsFor starters, the human race currently lacks the technology to get people to Mars and back. An interplanetary mission of that scale would likely be one of the most expensive and difficult engineering challenges of the 21st century. Currently, we don’t have the means to properly store enough fuel to make the trip, or a vehicle capable of landing people on the Martian surface. Last, and most importantly, we aren’t entirely sure that a ship will keep the astronauts alive long enough to get there.

This last issue was raised thanks to a recent confirmation made by the Curiosity rover, which finished calculating the number of high-energy particles that struck it during its eight month journey to Mars. Based on this data, NASA says that a human traveling to and from Mars could well be exposed to a radiation dose that is beyond current safety limits.

NASAsolar_radiationThis was performed with the rover’s Radiation Assessment Detector (RAD) instrument, which switched on inside as the cruise vessel began its 253-day, 560-million-km journey. The particles of concern fall into two categories – those that are accelerated away from our Sun and galactic cosmic rays (GCRs) – those that arrive at high velocity from outside of the Solar System. This latter category is especially dangerous since they impart a lot of energy when they strike the human body, can cause damage to DNA and are hard to shield against.

What’s more, this calculation does not even include time spent on the planet’s surface. Although Curiosity has already determined that planetary levels were within human tolerances, the combined dosage would surely lead to a fatal case of cancer for any career astronaut looking to take part in an “Ares Mission”. Cary Zeitlin from the Southwest Research Institute in Boulder, Colorado, and colleagues reported the Curiosity findings in the latest edition of Science magazine.

They claim that engineers will have to give careful consideration to the type of shielding that will need to be built into a Mars-bound crew ship. However, they concede that for some of the most damaging radiation particles, there may be little that can be done, beyond delivering them to Mars as quickly as possible. This presents an even greater challenge, which calls for the development of something better than existing propulsion technology. Using chemical propellants, Curiosity made the trip in eight months.

spaceX_elonmusk However, the good news is that at this juncture, nothing is technologically impossible about a manned Mars mission. It’s just a matter of determining what the priorities are and putting the time and money into developing the necessary tools. Right now NASA, other space agencies, and private companies are working to bring Mars within reach. And with time and further developments, who knows what will be possible by the time the 2020’s roll around?

Some alternatives include plasma and nuclear thermal rockets, which are in development and could bring the journey time down to a number of weeks. What’s more, SpaceX and other agencies are working on cheaper deliver systems, such as the grasshopper reusable rocket, to make sending ships into space that much more affordable. In addition, concepts for improving radiation shielding – like Inspiration Mars’ idea of using human waste – are being considered to cut down on the irradiation factor.

So despite the concerns, it seems that we are still on track for a Mars mission in 2030. And even if there are delays in the implementation, it seems as though a manned mission is just a matter of time at this point. Red Planet, here we come!

The Future is Here: Liver-Cells Made With 3D Printer

bioprinterOngoing developments in 3D printing have allowed for some amazing breakthroughs in recent years. From its humble beginnings, manufacturing everything from 3D models and drugs to jewelry, the technology is rapidly expanding into the realm of the biological. This began with efforts to create printed cartilage and skin, but quickly expanded into using stem cells to create specific types of living tissues. And as it happens, some of those efforts are bearing some serious fruit!

One such example comes to us from California, where the San Diego-based firm Organova announced that they were able to create samples of liver cells using 3D printing technology. The firm presented their findings at the Experimental Biology conference in Boston this past April. In a press release, the company said the following:

We have demonstrated the power of bioprinting to create functional human tissue that replicates human biology better than what has come before.

3dstemcellsThe company’s researchers used a gel and “bioink” to build three types of liver cells and arranged them into the same kind of three-dimensional cell architecture found in a human liver. Although not fully functional, the 3D cells were able to produce some of the same proteins as an actual liver does and interacted with each other and with compounds introduced into the tissue as they would in the body.

This latest breakthrough places Organovo, indeed all biomedical research firms, that much closer to the dream of being able to synthesize human organs and other complex organic tissues. And they are hardly alone in narrowing the gap, as doctor’s at the University of Michigan made a similar advancement last year when they used a 3D printer to build a synthetic trachea for a child with a birth defect that had collapsed her airway.

bioprinted heartAs scientists get more familiar with the technology and the process of building shaped, organic cells that are capable of doing the same job as their natural counterparts, we are likely to be seeing more and more examples of synthetic organic tissue. In addition, its likely to be just a few more years before fully-functional synthetic organs are available for purchase. This will be a boon for both those looking for a transplant, as well as a medical system that is currently plagued by shortages and waiting lists.

And be sure to check out this CBC video of Keith Murphy, CEO of Organovo, explaining the process of bioprinting:

The Future of the Classroom

virtual_learning2As an educator, technological innovation is a subject that comes up quite often. Not only are teachers expected to keep up with trends so they can adapt them into their teaching strategies, classrooms,and prepare children in how to use them, they are also forced to contend with how these trends are changing the very nature of education itself. If there was one thing we were told repeatedly in Teacher’s College, it was that times are changing, and we must change along with them.

And as history has repeatedly taught us, technological integration not only changes the way we do things, but the way we perceive things. As we come to be more and more dependent on digital devices, electronics and wireless communications to give us instant access to a staggering amount of technology, we have to be concerned with how this will effect and even erode traditional means of information transmission. After all, how can reading and lecture series’ be expected to keep kid’s attention when they are accustomed to lighting fast videos, flash media, and games?

envisioning-the-future-of-education

And let’s not forget this seminal infographic, “Envisioning the future of educational technology” by Envisioning Technology. As one of many think tanks dedicated to predicting tech-trends, they are just one of many voices that is predicting that in time, education will no longer require the classroom and perhaps even teachers, because modern communications have made the locale and the leader virtually obsolete.

Pointing to such trends as Massive Open Online Courses, several forecasters foresee a grand transformation in the not too distant future where all learning happens online and in virtual environments. These would be based around “microlearning”, moments where people access the desired information through any number of means (i.e. a google search) and educate themselves without the need for instruction or direction.

virtual_learning3The technical term for this future trend is Socialstructured Learning = an aggregation of microlearning experiences drawn from a rich ecology of content and driven not by grades but by social and intrinsic rewards. This trend may very well be the future, but the foundations of this kind of education lie far in the past. Leading philosophers of education–from Socrates to Plutarch, Rousseau to Dewey–talked about many of these ideals centuries ago. The only difference is that today, we have a host of tools to make their vision reality.

One such tool comes in the form of augmented reality displays, which are becoming more and more common thanks to devices like Google Glass, the EyeTap or the Yelp Monocle. Simply point at a location, and you are able to obtain information you want about various “points of interest”. Imagine then if you could do the same thing, but instead receive historic, artistic, demographic, environmental, architectural, and other kinds of information embedded in the real world?

virtual_learningThis is the reasoning behind projects like HyperCities, a project from USC and UCLA that layers historical information on actual city terrain. As you walk around with your cell phone, you can point to a site and see what it looked like a century ago, who lived there, what the environment was like. The Smithsonian also has a free app called Leafsnap, which allows people to identify specific strains of trees and botany by simply snapping photos of its leaves.

In many respects, it reminds me of the impact these sorts of developments are having on politics and industry as well. Consider how quickly blogging and open source information has been supplanting traditional media – like print news, tv and news radio. Not only are these traditional sources unable to supply up-to-the-minute information compared to Twitter, Facebook, and live video streams, they are subject to censorship and regulations the others are not.

Attractive blonde navigating futuristic interfaceIn terms of industry, programs like Kickstarter and Indiegogo – crowdsources, crowdfunding, and internet-based marketing – are making it possible to sponsor and fund research and development initiatives that would not have been possible a few years ago. Because of this, the traditional gatekeepers, aka. corporate sponsors, are no longer required to dictate the pace and advancement of commercial development.

In short, we are entering into a world that is becoming far more open, democratic, and chaotic. Many people fear that into this environment, someone new will step in to act as “Big Brother”, or the pace of change and the nature of the developments will somehow give certain monolithic entities complete control over our lives. Personally, I think this is an outmoded fear, and that the real threat comes from the chaos that such open control and sourcing could lead to.

Is humanity ready for democratic anarchy – aka. Demarchy (a subject I am semi-obsessed with)? Do we even have the means to behave ourselves in such a free social arrangement? Opinion varies, and history is not the best indication. Not only is it loaded with examples of bad behavior, previous generations didn’t exactly have the same means we currently do. So basically, we’re flying blind… Spooky!

Ending Cancer: “Canary” and Microscopic Velcro

cancer_cellEnding terminal illness is one of the hallmarks of the 21st century, with advances being made all the time. In recent years, efforts have been particularly focused on findings treatments and cures for the two greatest plagues of the past 100 years – HIV and cancer. But whereas HIV is one of the most infectious diseases to ever be observed, cancer is by far the greater killer. In 2008 alone, approximately 12.7 million cancers were diagnosed (excluding non-invasive cancers) and 7.6 million people died of cancer worldwide.

Little wonder then why so much time and energy is dedicated to ending it; and in recent years, a number of these initiatives have begun to bear fruit. One such initiative comes from the Mayo Clinic, where researchers claim they have developed a new type of software that can help classify cancerous lung nodules noninvasively, thus saving lives and health care costs.

lung-cancer-treatmentIt’s called Computer-aided Nodule Assessment and Risk Yield, or Canary, and a pilot study of the software recently appeared in the April issue of the Journal of Thoracic Oncology. According to the article, Canary uses data from high-resolution CT images of a common type of cancerous nodule in the lung and then matches them, pixel for pixel, to one of nine unique radiological exemplars. In this way, the software is able to make detailed comparisons and then determine whether or not the scans indicate the presence of cancer.

In the pilot study, Canary was able to classify lesions as either aggressive or indolent with high sensitivity, as compared to microscopic analyses of the lesions after being surgically removed and analyzed by lung pathologists. More importantly, it was able to do so without the need for internal surgery to allow a doctor to make a visual examination. This not only ensures that a patient could receive and early (and accurate) diagnosis from a simple CT scan, but also saves a great deal of money by making surgery unnecessary.

velcroAs they say, early detection is key. But where preventative medicine fails, effective treatments need to be available. And that’s where a new invention, inspired by Velcro comes into play. Created by researchers at UCLA, the process is essentially a refined method of capturing and analyzing rogue cancer cells using a Velcro-like technology that works on the nanoscale. It’s called NanoVelcro, and it can detect, isolate, and analyze single cancer cells from a patient’s blood.

Researchers have long recognized that circulating tumor cells play an important role in spreading cancer to other parts of the body. When the cells can be analyzed and identified early, they can offer clues to how the disease may progress in an individual patient, and how to best tailor a personalized cancer treatment. The UCLA team developed the NanoVelcro chip (see above) to do just that, trap individual cancer cells for analysis so that early, non-invasive diagnosis can take place.

NanoVelcro-deviceThe treatment begins with a patient’s blood being pumped in through the NanoVelcro Chip, where tiny hairs protruding from the cancer cells stick to the nanofiber structures on the device’s surface. Then, the scientists selectively cut out the cancer cells using laser microdissection and subject the isolated and purified cancer cells to single cell sequencing. This last step reveals mutations in the genetic material of the cells and may help doctors personalize therapies to the patient’s unique form of cancer.

The UCLA researchers say this technology may function as a liquid biopsy. Instead of removing tissue samples through a needle inserted into a solid tumor, the cancer cells can be analyzed directly from the blood stream, making analysis quicker and easier. They claim this is especially important in cancers like prostate, where biopsies are extremely difficult because the disease often spreads to bone, where the availability of the tissue is low. In addition, the technology lets doctors look at free-floating cancer cells earlier than they’d have access to a biopsy site.

Already, the chip is being tested in prostate cancer, according to research published in the journal Advanced Materials in late March. The process is also being tested by Swiss researchers to remove heavy metals from water, using nanomaterials to cling to and remove impurities like mercury and heavy metals. So in addition to assisting in the war on cancer, this new technology showcases the possibilities of nantechnology and the progress being made in that field.

Powered By The Sun: Visualizing Swanson’s Law

solar_power1For decades, solar power has been dogged by two undeniable problems that have prevented it from replacing fossil fuels as our primary means of energy. The first has to do the cost of producing and installing solar cells, which until recently remained punitively. The second has to do with efficiency, in that conventional photovoltaic cells remained inefficient as far as most cost per watt analyses went. But thanks to a series of developments, solar power has been beating the odds on both fronts and coming down in price.

However, to most people, it was unclear exactly how far it had come down in price. And thanks to a story recently published in The Economist, which comes complete with a helpful infographic, we are now able to see firsthand the progress that’s been made. To call it astounding would be an understatement; and for the keen observer, a certain pattern is certainly discernible.

PPTMooresLawaiIt’s known as the “Swanson Effect” (or Swanson’s Law), a theory that suggests that the cost of the photovoltaic cells needed to generate solar power falls by 20% with each doubling of global manufacturing capacity. Named after Richard Swanson, the founder of the major American solar-cell manufacturer named SunPower, this law is basically an imitation of Moore’s Law, which states that every 18 months or so, the size of transistors (and also their cost) halves.

What this means, in effect, is that in solar-rich areas of the world, solar power can now compete with gas and coal without the need for clean energy subsidies. As it stands, solar energy still accounts for only  a quarter of a percent of the planet’s electricity needs. But when you consider that this represents a 86% increase over last year and prices shall continue to drop, you begin to see a very trend in the making.

What this really means is that within a few decades time, alternative energy won’t be so alternative anymore. Alongside such growth made in wind power, tidal harnesses, and piezoelectric bacterias and kinetic energy generators, fossil fuels, natural gas and coal will soon be the “alternatives” to cheap, abundant and renewable energy. Combined with advances being made in carbon capture and electric/hydrogen fuel cell technology, perhaps all will arrive in time to stave off environmental collapse!

Check out the infographic below and let the good news of the “Swanson Effect” inspire you!:

The Future of Cities and Urban Planning

future-city-1With the development of vertical farms, carbon capture technology, clean energy and arcologies, the future of city life and urban planning is likely to be much different than it does today. Using current trends, there are a number of people who are determined to gain some understanding of what that might look like. One such group is Arup, a design and engineering firm that produced a mockup that visualizes what urban environments will look like in 2050.

Based on the world as it is today, certain facts about the future seem relatively certain. For starters, three-quarters of the population will live in cities, or 6.75 billion of the projected 9 billion global total. In addition, everyone will have grown up with the Internet, and its successors, and city residents will have access to less natural resources than they do today, making regeneration and efficiency more of a priority.

Add to this several emerging technologies, and our urban environments are likely to look something like the building mockup below. As you can see, it has its own energy systems (“micro-wind,” “solar PV paint,” and “algae facade” for producing biofuels). There is an integrated layer for meat, poultry, fish, and vegetable farming, a “building membrane” that converts CO2 to oxygen, heat recovery surfaces, materials that phase change and repair themselves, integration with the rest of the city, and much more.

future_urban_planning

Most futuristic of all is the fact that the structure is completely modular and designed to be shifted about (by robots, of course). The building has three layer types, with different life-spans. At the bottom is a permanent layer – with a 10 to 20-year lifespan – which includes the “facade and primary fit-out walls, finishes, or on-floor mechanical plant” – and a third layer that can incorporate rapid changes, such as new IT equipment.

As Arup’s Josef Hargrave described the building when unveiling the design:

[A]ble to make informed and calculated decisions based on their surrounding environment… [a] living and breathing [structure] able to support the cities and people of tomorrow.

In short, the building is designed with personal needs in mind, based on information gleamed from a person’s behaviors, stated preferences, and even genetic information.

aircleaning_skyscraper3But what is even more interesting is how these buildings will be constructed. As countless developments are made in the field of robotics, biotechnology and nanotechnology, both the materials used and the processes involved are likely to be radically different. The rigid construction that we are used to is likely to give way to buildings which are far more flexible, adaptive, and – best of all – built by robots, drones, tiny machines and bacteria cultures.

Once again, this change is due mainly to the pressures that are being placed on urban environments, and not just technological advances. As our world becomes even more densely populated, greater proportions of people live in urban environments, and resources become more constrained, the way we build our cities must offer optimum efficiency with minimal impact.

nanomachineryTowards this end, innovations in additive manufacturing, synthetic biology, swarm robotics, and architecture suggest a future scenario when buildings may be designed using libraries of biological templates and constructed with biosynthetic materials able to sense and adapt to their conditions.

What this means is that cities could be grown, or assembled at the atomic level, forming buildings that are either living creatures themselves, or composed of self-replicated machines that can adapt and change as needed. Might sound like science fiction, but countless firms and labs are working towards this very thing every day.

It has already been demonstrated that single cells are capable of being programmed to carry out computational operations, and that DNA strains are capable of being arranged to carry out specialized functions. Given the rapid progress in the field of biotech and biomimetics (technology that imitates biology), a future where the built environment imitates organic life seems just around the corner.

biofabrication For example, at Harvard there is a biotech research outfit known as Robobees that is working on a concept known as “programming group dynamics”. Like corals, beehives, and termite colonies, there’s a scalar effect gained from coordinating large numbers of simple agents to perform complex goals. Towards this end, Robobees has been working towards the creation of robotic insects that exhibit the swarming behaviors of bees.

Mike Rubenstein leads another Harvard lab, known as Kilobot, which is dedicated to creating a “low cost scalable robot system for demonstrating collective behaviors.” His lab, along with the work of researcher’s like Nancy Lynch at MIT, are laying the frameworks for asynchronous distributed networks and multi-agent coordination, aka swarm robotics, that would also be capable of erecting large structures thanks to centralized, hive-mind programming.

nanorobot1

In addition to MIT, Caltech, and various academic research departments, there are also scores of private firms and DIY labs looking to make things happen. For example, the companies Autodesk Research and Organovo recently announced a partnership where they will be combining their resources – modelling the microscopic organic world and building bioprinters – to begin biofabricating everything from drugs to nanomachines.

And then there are outfits like the Columbia Living Architecture Lab, a group that explores ways to integrate biology into architecture. Their recent work investigates bacterial manufacturing, the genetic modification of bacteria to create durable materials. Envisioning a future where bacterial colonies are designed to print novel materials at scale, they see buildings wrapped in seamless, responsive, bio-electronic envelopes.

ESA_moonbaseAnd let’s not forget 3D printing, a possibility which is being explored by NASA and the European Space Agency as the means to create a settlement on the Moon. In the case of the ESA, they have partnered with roboticist Enrico Dini, who created a 3-D printer large enough to print houses from sand. Using his concept, the ESA hopes to do the same thing using regolith – aka. moon dust – to build structures on Earth’s only satellite.

All of these projects are brewing in university and corporate labs, but it’s likely that there are far more of them sprouting in DIY labs and skunkworks all across the globe. And in the end, each of them is dedicated to the efficiency of natural systems, and their realization through biomimetic technology. And given that the future is likely to be characterized by resources shortages, environmental degradation and the need for security, it is likely to assume that all of these areas of study are likely to produce some very interesting scenarios.

As I’ve said many times before, the future is likely to be a very interesting place, thanks to the convergence of both Climate Change and technological change. With so many advances promising a future of post-scarcity, post-mortality, a means of production and a level of control over our environment which is nothing short of mind-boggling – and a history of environmental degradation and resource depletion that promises shortages, scarcity, and some frightening prospects – our living spaces are likely to change drastically.

The 21st century is going to be a very interesting time, people. Let’s just hope we make it out alive!

Judgement Day Update: The Robotic Bartender and DARPA’s Latest Hand

robot_bartenderRobots have come a long way in recent years, haven’t they? From their humble beginnings, servicing human beings with menial tasks and replacing humans on the assembly line, they now appear poised to take over other, more complex tasks as well. Between private companies and DARPA-developed concepts, it seems like just a matter of time before a fully-functioning machine is capable of performing all our work for us.

One such task-mastering robot was featured at the Milan Design Week this year, an event where fashion tales center stage. It’s known as the Makr Shakr, a set of robotic arms that are capable of mixing drinks, slicing fruit, and capable of making millions of different recipes. The result of a collaborative effort between MIT SENSEable City Lab and Carlo Ratti Associati, an Italian architecture firm, this robot is apparently able to match wits with any human bartender.

robot_bartender1While at the Milan Design Week, the three robotic arms put on quite the show, demonstrating their abilities to a crowd of wowed spectators. According to the website, this technology is not just a bar aid, but part of a larger movement in robotics:

Makr Shakr aims to show the ‘Third Industrial Revolution’ paradigm through the simple process design-make-enjoy, and in just the time needed to prepare a new cocktail.

In a press release, the company described the process. It begins with the user downloading an app to create their order to the smartphone as well as peruse the recipes that other users have come up with. They then communicate the order to the Makr Shakr and “[the] cocktail is then crafted by three robotic arms, whose movements reproduce every action of a barman–from the shaking of a Martini to the muddling of a Mojito, and even the thin slicing of a lemon garnish.”

robot_bartender2Inspired by the ballerina Roberto Bolle, whose “movements were filmed and used as input for the programming of the Makr Shakr robots”, the arms appear most graceful when they do their work. In addition, the design system monitors exactly how much booze each patron is consuming, which, in theory, could let the robot-bartenders know when it’s time to cut off designers who have thrown back a few too many.

Check out the video of the Makr Shakr in action:


Another major breakthrough comes, yet again, from DARPA. For years now, they have been working with numerous companies and design and research firms in order to create truly ambulatory and dextrous robot limbs. In some cases, as with the Legged Squad Support System (LS3), this involves creating a machine that can carry supplies and keep up with troops. In others, this involves the creation of robotic hands and limbs to help wounded veterans recover and lead normal lives again.

And you may recall earlier this year when DARPA unveiled a cheap design for a robotic hand that was able to use tools and perform complex tasks (like changing a tire). More recently, it showcased a design for a three-fingered robot, designed in conjunction with the firm iRobot – the makers of the robotic 3D printer – and with support from Harvard and Yale, that is capable of unlocking and opening doors. Kind of scary really…

DARPA_robot

The arm is the latest to come out of the Autonomous Robotic Manipulation (ARM) program, a program designed to create robots that are no longer expensive, cumbersome, and dependent on human operators. Using a Kinect to zero in on the object’s location before moving in to grab the item, the arm is capable of picking up thin objects lying flat, like a laminated card or key. In addition, the hand’s three-finger configuration is versatile, strong, and therefore capable of handling objects of varying size and complexity.

When put to the test (as shown in the video below), the hand was able to pick up a metal key, insert it into a lock, and open a door without any assistance. Naturally, a human operator is still required at this stage, but the use of a Kinect sensor to identify objects shows a degree of autonomous capability, and the software behind its programming is still in the early development phase.

And while the hand isn’t exactly cheap by everyday standards, the production cost has been dramatically reduced. Hands fabricated in batches of 1,000 or more can be produced for $3,000 per unit, which is substantially less than the current cost of $50,000 per unit for similar technology. And as usual, DARPA has its eye on future development, creating hands that would be used in hazardous situations – such as diffusing IEDs on the battlefield – as well as civilian and post-combat applications (i.e. prosthetics).

And of course, there’s a video for the ARM in action as well. Check it out, and then decide for yourself if you need to be scared yet:

The Arkyd 100: Crowdfunding Space Exploraiton

ARKYD-in-SpacePlanetary Resources made quite the impression last year when they announced their plans to begin prospecting near-Earth asteroids with in the intention of mining them in the near future. Alongside such companies as SpaceX and Golden Spike, they are part of a constellations of private interests looking to establish commercial space travel and tourism. But their latest proposal goes a step further, bringing crowdfunding and the realm of space exploration together.

That’s the idea behind a Kickstarter campaign that the company began to raise money for a crowdfunded space telescope. Known as the Arkyd 100, the company claims that this new telescope will provide unprecedented public access to space and place the most advanced exploration technology into the hands of students, scientists and a new generation of citizen explorers.

asteroid_miningTo make their campaign successful, they need to raise $1 million in Kickstarter pledges by the end of June 2013. Once the telescope is up and running, it will allow them to better map the asteroid belt, thus assisting them in finding the rocks they want to mine for precious metals and trace elements. And with public financial backers making it happen, anyone pledging money will be able to own a piece of the prospector!

During a webcast on May 28th to announce the Kickstarter campaign, Chris Lewicki, President and Chief Engineer for Planetary Resources, gave a rundown on the details of the telescope. And interestingly enough, the Planetary Resources’ technical team that designed it also worked on every recent U.S. Mars lander and rover. So if you do choose to invest, you will do so with the knowledge that the same people who helped build the Opportunity and Curiosity rovers are behind this project. If that doesn’t inspire investor confidence, I don’t know what will!

ARKYD-Space-SelfieA wide array of scientists, space enthusiasts and even Bill Nye the Science Guy have voiced their support for Planetary Resources’ new public space telescope. And those who invest will have the chance of recouping certain rewards, depending on how much they choose to pledge. Those pledging the minimum donation of $25 will receive the “Your Face in Space” benefit, where you will have you picture placed on the Arkyd and receive a picture of said photo the telescope with Earth in the background. Higher pledges will provide access to the telescope for students and researchers worldwide.

After less than 2 hours into their campaign, Planetary Resources had raised over $100,000. And as of this article’s writing, just one day shy of a week, the campaign has reached $710,945 of their $1 million goal, and they still have 27 days left. I guess people want a piece of this project. And who can blame them, since it is a scientific and historic first!

The Future is Here: The Anti-Gravity 3D Printer

anti-grav3d2Three-dimensional printing is without a doubt one of the greatest growth industries of the 21st century. And yet, surprisingly enough, there are those who seem to think that there is room for improvement when it comes to current concepts and designs. Two such individuals are Petr Novikov and Saša Jokic, a group of architecture students who recently began interning at the Joris Laarman Lab in Amsterdam. While there, they came up with a revolutionary method for 3D printing that reboots the concept!

It’s called Mataerial, a new and patented process where polymers are squeezed from a nozzle similar to how bakers squeeze icing from a tube to frost a cake, except there’s a robot involved. Ultimately, their concept was based on the fact that all conventional printing works with layers, which they considered grossly inefficient. Not only do such methods require the presence of a support structure, they also take additional time, materials, and increase the risk of damage if the object is removed from its support structure.

anti-grav3d1As Novikov explains:

The material that comes out of the nozzle is still kind of viscous–It’s not a liquid already but its not a solid material, so what we wanted to do is make it solid the same exact moment it comes out of the nozzle. And that’s the hardest part. Because if it solidifies before it comes out of the nozzle, then its going to make a clog… but if it solidifies after it leaves the nozzle, than its going to be weak and fall down.

The key was to find two liquid polymers that, when mixed, quickly harden, which allows for mid-air solidification. They’re calling the resulting method “Anti-Gravity Object Modeling,” since the material’s just-in-time solidification eschews the need for any sort of support structure. The new method is exciting for a number of reasons. The first is scale, in that this method could be adapted for manufacturing large and well as small scale objects easily.

anti-grav3dDepending on the size of nozzle used, the technology could be used to print materials and objects that are on the scale of millimeters (like components for consumer electronics), 3D models (the kinds that are printed by standard professional printers), or larger objects such as furniture or even parts used in large-scale architectural construction. Basically, anything from the tiniest object to the largest structure could be created by robots equipped with specialized nozzles and Mataerial printers.

But perhaps most exciting is the possibility that this new method would be able to print objects in low or even zero gravity. Given NASA’s recent interest in building a Moon base using 3D printing, such a process could come in mighty useful. Already, the technology known as “sintering” has been considered for the purposes of building a Lunar settlement, but given its “anti-gravity” application, the Mataerial process just might have a shot at winning some lucrative contracts.

In fact, Navikov indicates that they considered the possibility and put it to the test. As he indicated: “We did an investigation and we are pretty sure that this could be used as 3-D printer in zero gravity.” Did you get that NASA? Anyway to make this technology work with regolith? Regardless, it sure could be useful here on planet Earth!

Supercomputer Creates Atomic Model of HIV

DNA-1The ongoing fight to end HIV has been a long and arduous one, but progress is being made. In addition to potential treatments being created that have shown promise, there are also efforts being mounted to understand how the virus works at an atomic level. This is great news, for as any practitioner of medicine will tell you, understanding a disease and knowing how to strike at the heart of it is the key to stopping it and making sure future generations don’t have to fear it.

In recent years, several major breakthroughs were announced for the treatment of HIV, treatments which many heralded as cures. In January of last year, the Danish Research Council awarded funding to a group of researchers who demonstrated that HIV could be “flushed” from infected cells where it tends to congregate and protect itself. Combined with vaccinations that turbocharge the body’s immune system, this method proved effective at eliminating the HIV virus in infected cells.

HIV-budding-ColorAnother came back in November, when researchers at Caltech were even able to successfully spawn a significant amount of HIV antibodies in lab mice by using a new approach, known as Vectored ImmunoProphylaxis (VIP). An inversion of the traditional vaccination method, this new method produced plenty of HIV-preventing antibodies which they believed could be fashioned into a  vaccine.

And finally, there were the experiments being conducted over at the Washington University School of Medicine, where researchers designed a solution that employed bee venom and a nanoparticle delivery system. Knowing that bee venom is capable of killing HIV, and that the virus is thousands of times smaller than your average cell, the solution proved quite effective at filtering out the virus and killing it while leaving surrounding tissue unharmed. Taken together, these two proposed solutions have left many thinking a cure is just around the corner.

Hence why a group of scientists – using the University of Illinois’ “Blue Waters” supercomputer — have developed a new series of computer models that are finally giving researchers an atomic-level look at the formidable barrier mechanism enclosing the heart of the virus.

For example, its been known for some time that the HIV virus it’s covered in several layers of protective proteins. But beneath that outer shell resides a conical structure called the capsid, which houses the virus’ payload of genetic material. (See diagram below.) When HIV invades a cell, it’s the capsid that opens up to initiate the takeover process, allowing the virus to replicate inside the healthy host cell. Better understanding of how this mysterious delivery system operates could be one of the final steps to finding a cure.

HIVAnd that’s where the modelling software really comes into play. How and when the HIV cell opens to deliver the capsid has long eluded researchers, and as Klaus Schulten, a physicist that was part of the team that modeled the virus, pointed out: “The timing of the opening of the capsid is essential for the degree of virulence of the virus.”

Using the Blue Waters, Schulten and his associates managed to map out the model all 64 million of the capsid’s atoms. Through countless simulations, they also discovered that the capsid’s microscopic outer casing is composed of 216 hexagon-shaped proteins that fit together in a honeycomb formation. These hexagonal structures are what give the capsid it’s tough outer shell and allow it to be such a harmful and insidious killer.

AIDS_memorialThis painstakingly delicate process would have been unthinkable until just a few years ago, and represents the most complete picture of the HIV virus to date. What’s more, knowing what HIV looks like at the atomic level will help scientists to understand the timing of the virus’ delivery system. Since the opening of the virus’ protective layer is when it’s most vulnerable, Schulten and his colleagues hope to determine the precise timing of this event so a treatment can be developed that could attacks the virus at this exact moment.

Think of it as throwing a bomb into the mouth of a terrible war machine, right as it opens up its armored maw to bite you! Better yet, think of it as another step on the road to ending one of the greatest plagues humankind has ever had to deal with. Safety for the future, and justice for the victims!
