Global Warming Evidence: 2007 Report Compared to 2013 (Infographic) by Ross Toro, Infographics Artist

Global Warming Evidence: 2007 Report Compared to 2013 (Infographic)

by Ross Toro, Infographics Artist
Infographic: How the 2013 global warming report compares to 2007's.

Observed changes in climate and greenhouse gases could be accounted for by human activity, according to a report by the Intergovernmental Panel on Climate Change (IPCC). Observations of the climate system are based on direct measurements and remote sensing from satellites and other platforms.
IPCC's 2007 report compared with 2013's:
TEMPERATURE
2007: 1995-2006 rank among the 12 warmest years in the instrumental record of global surface temperature (since 1850).
2013: Each of the last three decades has been successively warmer at the Earth’s surface than any preceding decade since 1850. 
 
SEA LEVEL
2007: Global average sea level has risen since 1961 at an average rate of 1.8 millimeters/yr and since 1993 at 3.1mm/yr.
2013: The rate of sea level rise since the mid-19th century has been larger than the mean rate during the previous two millennia.
 
SNOW AND ICE
2007: Observed decreases in snow and ice extent are also consistent with warming.
2013: Over the last two decades, the Greenland and Antarctic ice sheets have been losing mass and glaciers have continued to shrink almost worldwide.
 
NORTHERN HEMISPHERE
2007: Average Northern Hemisphere temperatures during the second half of the 20th century were very likely higher than during any other 50-year period in the last 500 years and likely the highest in at least the past 1,300 years.
2013: In the Northern Hemisphere, 1983–2012 was likely the warmest 30-year period of the last 1,400 years (medium confidence). Northern Hemisphere spring snow covers have continued to decrease.
 
OCEANS
2007: Observational evidence from all continents and most oceans shows that many natural systems are being affected by regional climate changes, particularly temperature increases.
2013: The global ocean will continue to warm during the 21st century. Heat will penetrate from the surface to the deep ocean and affect ocean circulation.
 
ECOSYSTEMS
2007: In terrestrial ecosystems, earlier timing of spring events and poleward and upward shifts in plant and animal ranges are with very high confidence linked to recent warming.
2013: Continued emissions of greenhouse gases will cause further warming and changes in all components of the climate system.

Guys Build $1.6 Million Batman Tumbler Replica

Guys Build $1.6 Million Batman Tumbler Replica

We are living in an age inspired by the cinema and science. All that which we only saw in animated movies is becoming real thanks to science. You can see superheroes taking off in flight to fight off crime in movies and thanks to the technological advancement it all seems as real as it can get. We all are fans of Christopher Nolan’s Batman; do you remember the Epic’s EV TORQ; The Roadster straight out of Batman’s movie? Yes, we covered that too because like most of the readers we too are huge, die-hard, fans of Batman. Things keep getting better and better for us fans, believe us! Have you all heard about the Gumball 3000 race? Traditionally, the race was about unique cars just out there on the road completing the rally.

Team GalagHowever, nowadays it’s more about Ferrari, Lamborghini and expensive cars like that. Amongst all such expensive cars, the international racing crew; Team Galag have introduced one of their unique cars for the Gumball 3000 race set for 2013. What is so surprising about this car? Well, yes it has something to do with the Christopher Nolan’s Dark Knight. But this is much more than what you were expecting; this is an exact replica of ‘does this come in black-tank’ driven by our Dark Knight on the streets of Gotham. As mentioned earlier, the Gumball race 3000 is not like the traditional racing competitions. There is neither time record to break nor any prizes to be given to fastest cars. This is more like a road trip through Europe on flashy and expensive cars. An exotic trip if you will. The event was inspired by movies such as The Cannonball Run and The Gumball Rally. The event, traditionally, used to have both types; the expensive sort and the unique ones. However, it has somewhat turned into a ‘let’s see who’s the richest one out there’ rally sort. The members of Team Galag wanted to reignite the old spirit of the rally and therefore commissioned Parker Brothers Concepts, in Florida, to create a replica of Batman Tumbler which was street legal. The other than obvious task was to come up with something that would be able to compete with other cars in the rally during this 3,000 m rally. An investment of $1.6 million was made for this awesome crime fighting ride.
Team Galag working
Batman Tumbler Replica 2
Let’s have a look at some of the specs of this cool ride; it weighs about 2.5 tons and is about 2 ft higher than a Hummer H1. We have a 400lb, 6.2 liter V8 engine which is surrounded by a bespoke tubular chassis. The car is not lightning fast but considering its weight and size, we would say its ability to achieve 100 mph is definitely something worth appreciating. Hats off to the manufacturing team!  One can even track this car during rally by signing onto Team Galag’s website. They have a pretty slick GPS tracking system just for this purpose. Rest assured the car is bound to get quite an appraisal at the rally!

 

Medical Sensors Improve With Holey Gold Nanostructures

Medical Sensors Improve With Holey Gold Nanostructures

Sep. 26, 2013 — A new method that fabricates gold nanostructures quickly and efficiently could lead to highly sensitive, portable medical sensorsRecent advances in nanotechnology are providing new possibilities for medical imaging and sensing. Gold nanostructures, for example, can enhance the fluorescence of marker dyes that are commonly used to detect biomolecules and diagnose specific diseases.

Now, Ping Bai at the A*STAR Institute of High Performance Computing, Singapore, and co-workers have developed a fast and inexpensive way to fabricate arrays of gold nanoholes. The researchers have shown that sensor chips built using these nanostructures can accurately detect cancer-related molecules in blood and are small enough to be used in portable medical devices.
Nanohole arrays are designed so that incident light of certain wavelengths will induce large-scale oscillations of the gold electrons, known as localized surface plasmon resonance (SPR). The localized SPR focuses the absorbed light energy to enhance fluorescence (see image).
"Commercial SPR systems are already used in hospital laboratories, but they are bulky and expensive," says Bai. "We would like to develop small, handheld devices for on-the-spot clinical use. This requires localized SPR, for which we need nanohole arrays."
Previously, nanohole arrays have been created using electron-beam lithography (EBL), which is expensive and time consuming. Bai and co-workers used EBL to create a nickel mold and then used the mold to print nanohole patterns onto a photoresist material. The researchers made the nanostructures by evaporating gold onto the patterned structure before peeling off the photoresist material. Because the nickel mold can be reused many times, this method -- called nano-imprinting -- can produce large numbers of gold nanohole arrays.
"We fabricated arrays of 140 nanometer-square nanoholes with very few defects," says Bai. As a first demonstration, the researchers showed that a sensor chip made with their nanohole arrays could detect prostate cancer antigens in blood, and was ten times more sensitive than an identical device that used a gold film without nanoholes. Optimizing the chip design would further improve the sensitivity, Bai notes.
The team believes that these chips could be incorporated into cheap and portable point-of-care devices for rapid diagnosis of diseases such as dengue fever. "The microfluidic cartridge built using our nanohole arrays is about the size of a credit card," says Bai. "In the future, we hope to build detectors that use very simple light sources, such as LEDs, and simple detectors similar to smartphone cameras. These devices will have widespread applications across medical science and could even be used to detect contaminants in food, water or the air."

Accelerator On a Chip: Technology Could Spawn New Generations of Smaller, Less Expensive Devices for Science, Medicine

Accelerator On a Chip: Technology Could Spawn New Generations of Smaller, Less Expensive Devices for Science, Medicine


The key to the accelerator chips is tiny, precisely spaced ridges, which cause the iridescence seen in this close-up photo. (Credit: Matt Beardsley, SLAC National Accelerator Laboratory)
The achievement was reported today in Nature by a team including scientists from the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory and Stanford University.
"We still have a number of challenges before this technology becomes practical for real-world use, but eventually it would substantially reduce the size and cost of future high-energy particle colliders for exploring the world of fundamental particles and forces," said Joel England, the SLAC physicist who led the experiments. "It could also help enable compact accelerators and X-ray devices for security scanning, medical therapy and imaging, and research in biology and materials science."
Because it employs commercial lasers and low-cost, mass-production techniques, the researchers believe it will set the stage for new generations of "tabletop" accelerators.
At its full potential, the new "accelerator on a chip" could match the accelerating power of SLAC's 2-mile-long linear accelerator in just 100 feet, and deliver a million more electron pulses per second.
This initial demonstration achieved an acceleration gradient, or amount of energy gained per length, of 300 million electronvolts per meter. That's roughly 10 times the acceleration provided by the current SLAC linear accelerator.
"Our ultimate goal for this structure is 1 billion electronvolts per meter, and we're already one-third of the way in our first experiment," said Stanford Professor Robert Byer, the principal investigator for this research.
Today's accelerators use microwaves to boost the energy of electrons. Researchers have been looking for more economical alternatives, and this new technique, which uses ultrafast lasers to drive the accelerator, is a leading candidate.
Particles are generally accelerated in two stages. First they are boosted to nearly the speed of light. Then any additional acceleration increases their energy, but not their speed; this is the challenging part.
In the accelerator-on-a-chip experiments, electrons are first accelerated to near light-speed in a conventional accelerator. Then they are focused into a tiny, half-micron-high channel within a fused silica glass chip just half a millimeter long. The channel had been patterned with precisely spaced nanoscale ridges. Infrared laser light shining on the pattern generates electrical fields that interact with the electrons in the channel to boost their energy.
Turning the accelerator on a chip into a full-fledged tabletop accelerator will require a more compact way to get the electrons up to speed before they enter the device.
A collaborating research group in Germany, led by Peter Hommelhoff at the Max Planck Institute of Quantum Optics, has been looking for such a solution. It simultaneously reports in Physical Review Letters its success in using a laser to accelerate lower-energy electrons.
Applications for these new particle accelerators would go well beyond particle physics research. Byer said laser accelerators could drive compact X-ray free-electron lasers, comparable to SLAC's Linac Coherent Light Source, that are all-purpose tools for a wide range of research.
Another possible application is small, portable X-ray sources to improve medical care for people injured in combat, as well as provide more affordable medical imaging for hospitals and laboratories. That's one of the goals of the Defense Advanced Research Projects Agency's (DARPA) Advanced X-Ray Integrated Sources (AXiS) program, which partially funded this research. Primary funding for this research is from the DOE's Office of Science.
 

 


Lernstift – a Pen That Warns for Mistakes

Lernstift is a digital pen  
that recognizes writing errors and points them out with a subtle vibration – like a friend looking you over the shoulder as you write. Lernstift works fully autonomous – without further external devices or special paper.

Two central functions

Learning to write bears two main challenges: writing legibly and writing correctly. Lernstift helps with both – from legibly writing one's very first letters down to the correct spelling of exotic fruits on your shopping list.

Calligraphy mode


In Calligraphy Mode the pen vibrates once if a letter is written wrong or illegibly.

Orthography mode


In Orthography Mode the pen vibrates once for a misspelled word and twice to point out grammatical errors in a sentence.

Lernstift Apps

Lernstift is an innovative learning aid for kids and adults.
The sophisticated electronics recognize all writing movements and points out mistakes as they are being made – with an unmistakeable vibration.

Via Wi-Fi the pen can be connected to computers and smart devices. With the help of apps one can measure the learning progress. A broad range of other apps will be developed – from interactive learning games to digital note-taking and co-writing solutions all the way down to social media sharing and an own Lernstift community.

Learning success measurement

Lernerfolgsmessung

Live monitoring

Further Features

Unlike other digital pens Lernstift is truly multifaceted – in both the visual and functional design.

Exchangeable writing tips: pencil, fountain pen, ballpoint

Austauschbare Schreib-Systeme! Füllhalter, Bleistift und Rollerball
With its exhangeable writing system the pen can be easily turned into a pencil, fountain pen or ballpoint.

Color variants for girls and boys, mothers and fathers

Farbvariationen für Mädchen und Jungen, Väter und Mütter
Boys will be boys and most girls do have a feminine style most of the time; that's why Lernstift will be available in respective colors.

Language versions

Upon launch, Lernstift will be available in English and German. Step by step we will then introduce further languages; depending on the demand.

The future of penmanship

A perfectly easy way to learn to write perfectly

For centuries mankind has been learning to write. All this time, we have depended on someone looking over our shoulder as we write, or correcting spelling, grammar and form afterwards.
In the future we can get our feedback another way – and more importantly: instantly! With Lernstift. It combines a time-tested writing utensil with state of the art technology and thereby gives writing by hand new relevance and appeal in the age of the iPad.
The integrated electronics recognize mistakes as they are being made and give the writer feedback by vibrating. In other words:
Lernstift is a great way to learn how to write faster. And what’s more: Lernstift is great fun, too!

It may look like a child’s toy - but this tiny remote control helicopter has become massively important to the Army in the fight against the Taliban.
Troops in Afghanistan program the Black Hornet drone to fly deep into enemy territory and take pictures with three tiny cameras fitted in its nose before returning to base.


The 8in drones are so small that they can fit easily in a soldier’s hand and weigh just over half an ounce including their batteries.
They are being used by soldiers from the Brigade Reconnaissance Force at Camp Bastion in Afghanistan.

  Commanding officer Major Adam Foden, 53, said: “Black Hornet is a game-changing piece of kit.
"Previously, we would have had to send soldiers forward to see if there were any enemy fighters hiding inside a set of buildings.
"Now we are deploying Black Hornet to look inside compounds and to clear a route through enemy-held spaces.
“It has worked very well and the pictures it delivers back to the monitor are really clear and Black Hornet is so small and quiet that the locals can’t see or hear it.”
The Black Hornet has a rechargeable battery and is controlled by members of the unit using a joystick similar to those on video games .
The drone can fly at speeds of up to 22mph during each 30-minute reconnaissance mission.
As it hovers near enemy positions, high-resolution images are beamed back to Camp Bastion.
One soldier said: “The Black Hornet is really cool. The pictures are amazingly clear and we can see who is a local civilian and who is a Taliban fighter and whether any weapons are being stored there.
“We can then make our plans accordingly. It saves a lot of time and prevents a lot of mistakes.
"It can zoom right up to somebody’s face and hold that frame for as long as is required so we can identify them without them even knowing it’s there.”
 
Hi-tech and deadly
British soldiers operating in Afghanistan are equipped with a variety of hi-tech equipment.
The latest rifle – the SA80 A2 – is fitted with a high-definition sight which helps them to pinpoint targets more quickly.
The A2 has a range of up to 300 metres and has been used to devastating effect.
It is superior to its predecessors because it is fully automatic and sealed so less likely to get sand in it.
Troops are also supplied with state-of-the-art sunglasses which protect them from bomb blasts as well as sunlight.
The glasses are fitted with yellow lenses which enable them to make eye contact with civilians – which is seen as highly important when communicating.

Take A Look At The World That Awaits Us In 2050

Photoshopping The Future: Take A Look At The World That Awaits Us In 2050

British environmentalist Jonathan Porritt offers a photo-realistic vision of life on Earth in the year 2050. (Spoiler alert: the future does not exactly go smoothly.)


Jonathan Porritt can talk until he's blue in the face about concentrated solar power plants, advanced anaerobic digestion, and aquacycle technology. The British environmentalist has addressed all of that and more as founding director of Forum for the Future. But in his new book The World We Made (October, Phaidon Press), Porritt goes way beyond mere verbiage to offer a photo-realistic vision of life on Earth in the year 2050.
"The underlying philosophy for this book is simple," Porritt tells Co.Create. "I've been trying to do sustainable advocacy for four decades. Even when I'm lucky enough to make a hit with something intellectually, lots of people tell me, 'That's really interesting Jonathan but I still can't see what a sustainable world looks like.' I realized I can't do words any longer because words alone won't cut it. I've got to do words plus visuals."
The World We Made looks back, 37 years from now, on a fitful cavalcade of catastrophes and breakthroughs as seen through the eyes of fictitious professor Alex McHale. He describes how famine, cyber-terrorism, and riots gradually convinced politicians, entrepreneurs, and technologists to innovate their way toward a self-sustaining planet.
While the graphics illustrating Porritt's speculative history share a utopian aesthetic, each visualization finds firm footing in technologies that already exist. "We didn't want to tell a science-fiction story," says Porritt. "It has to look real to people but it also has to look powerful and compelling. The key word for me is aspirational, as in, 'Yeah, 'That looks good. I'd like to live there.'"



Porritt makes no apologies for his optimistic projections about where the world is headed. He said, "There's no mis-match between my own ambitions for myself, my family, and my community and what's being presented in this book. It's taken me 40 years to learn about the psychology of change, and without aspiration, political systems don't work, individual ambition doesn't kick in."

World Record Solar Cell With 44.7% Efficiency

World Record Solar Cell With 44.7% Efficiency

Sep. 23, 2013 — The Fraunhofer Institute for Solar Energy Systems ISE, Soitec, CEA-Leti and the Helmholtz Center Berlin jointly announced today having achieved a new world record for the conversion of sunlight into electricity using a new solar cell structure with four solar subcells. Surpassing competition after only over three years of research, and entering the roadmap at world class level, a new record efficiency of 44.7% was measured at a concentration of 297 suns. This indicates that 44.7% of the solar spectrum's energy, from ultraviolet through to the infrared, is converted into electrical energy. This is a major step towards reducing further the costs of solar electricity and continues to pave the way to the 50% efficiency roadmap.

Back in May 2013, the German-French team of Fraunhofer ISE, Soitec, CEA-Leti and the Helmholtz Center Berlin had already announced a solar cell with 43.6% efficiency. Building on this result, further intensive research work and optimization steps led to the present efficiency of 44.7%.
These solar cells are used in concentrator photovoltaics (CPV), a technology which achieves more than twice the efficiency of conventional PV power plants in sun-rich locations. The terrestrial use of so-called III-V multi-junction solar cells, which originally came from space technology, has prevailed to realize highest efficiencies for the conversion of sunlight to electricity. In this multi-junction solar cell, several cells made out of different III-V semiconductor materials are stacked on top of each other. The single subcells absorb different wavelength ranges of the solar spectrum.
"We are incredibly proud of our team which has been working now for three years on this four-junction solar cell," says Frank Dimroth, Department Head and Project Leader in charge of this development work at Fraunhofer ISE. "This four-junction solar cell contains our collected expertise in this area over many years. Besides improved materials and optimization of the structure, a new procedure called wafer bonding plays a central role. With this technology, we are able to connect two semiconductor crystals, which otherwise cannot be grown on top of each other with high crystal quality. In this way we can produce the optimal semiconductor combination to create the highest efficiency solar cells."
"This world record increasing our efficiency level by more than 1 point in less than 4 months demonstrates the extreme potential of our four-junction solar cell design which relies on Soitec bonding techniques and expertise," says André-Jacques Auberton-Hervé, Soitec's Chairman and CEO. "It confirms the acceleration of the roadmap towards higher efficiencies which represents a key contributor to competitiveness of our own CPV systems. We are very proud of this achievement, a demonstration of a very successful collaboration."
"This new record value reinforces the credibility of the direct semiconductor bonding approaches that is developed in the frame of our collaboration with Soitec and Fraunhofer ISE. We are very proud of this new result, confirming the broad path that exists in solar technologies for advanced III-V semiconductor processing," said Leti CEO Laurent Malier. Concentrator modules are produced by Soitec (started in 2005 under the name Concentrix Solar, a spin-off of Fraunhofer ISE). This particularly efficient technology is employed in solar power plants located in sun-rich regions with a high percentage of direct radiation. Presently Soitec has CPV installations in 18 different countries including Italy, France, South Africa and California.

Animated videos introduce stem cell science in one-minute bursts

Animated videos introduce stem cell science in one-minute bursts

StemCellShorts – created by young Canadian researchers – are narrated by renowned scientists         

Two Canadian researchers with a passion for animation and the communication of science have created a series of one-minute videos to introduce basic concepts in stem cell research.
The first of three – What is a stem cell? – premieres today on Signals, the official blog of the Stem Cell Network, which helped fund the videos, and the Centre for Commercialization of Regenerative Medicine.
Ben PaylorBen Paylor
Mike Long, PhDMike Long, PhD
The videos are the brainchild of Ben Paylor , a PhD candidate in Experimental Medicine at the University of British Columbia, and Dr. Mike Long, a post-doctoral fellow at the University of Toronto, who pitched the idea for the video series through a Public Outreach Award offered by the Stem Cell Network. They channeled the $5,000 in seed funding from the award through their Vancouver-based animation studio, InfoShots, engaging award-winning animator David Murawsky and Emmy-nominated composer James Wallace to create the animations and music for the films.
InfoShots, which they founded in 2011, specializes in explaining complex topics in simple terms. Current projects including animations that explain scientific papers, grants and the research of individual labs.


Narrated by the 'father of stem cell research'

Jim Till, PhDJim Till, PhD
To give the videos credibility and make an impact in the scientific community, they worked with the Stem Cell Network to enlist world-renowned stem cell scientists to narrate the videos. "Animation is an excellent medium for explaining complex topics in a very simple and engaging manner," said Paylor, an 2012-13 Action Canada fellow. "And being able to secure such prestigious narrators … was the icing on the cake."
The first video features the voice of Dr. Jim Till, who, along with Dr. Ernest McCulloch, first identified stem cells from bone marrow in 1961.Their description of stem cell characteristics became the foundation of the field of stem cellresearch. These concepts that are revealed in the first video which is targeted at youth of high-school age and older.
"I felt that it was important to contribute to What is a stem cell? because of the fortuitous involvement of Dr. Ernest McCulloch and myself in what turned out to be the foundation of a new field of experimental stem cell research," said Dr. Till.
He said he hoped the authenticity of the scientists' voices on the videos would help make the films more appealing to young people.

Communicating Science

Elsevier Connect's Communicating Science feature deals with all aspects of science communication, including creative ways researchers are presenting science to reach a broader audience. If you have a project or story you would like to present on Elsevier Connect, please submit your idea to Editor-in-Chief Alison Bert: ECEditor@elsevier.com.
The remaining two videos are "What is an embryonic stem cell?" narrated by Dr. Janet Rossant, Chief of Research at SickKids Hospital of the University of Toronto, and "What is an induced pluripotent stem cell?" narrated by Dr. Mick Bhatia, Director of the McMaster University Stem Cell and Cancer Research Institute in Hamilton, Ontario.
They will be posted on the Signals Blog on October 11 and October 25 respectively.
In addition, the world screening premiere will be held at the 2013 Till & McCulloch Meetings October 24 in Banff, Alberta.
All videos will be hosted on the Stem Cell Network's vimeo channel: vimeo.com/stemcellnetwork.
For Paylor and Long, the work is far from complete. They recently received a second Public Outreach Award and matching funds from the Canadian Stem Cell Foundation to produce five more videos, which will be released in the spring.

Future Laptops Could Be Powered By Typing

Future Laptops Could Be Powered By Typing


Charge your laptop by typing on it — sounds like a perfect idea to one who believes in the ideal world. But this could soon become a reality as Researchers from the Royal Melbourne Institute of Technology (RMIT) have successfully measured a piezoelectric thin film’s capacity for turning mechanical pressure into electricity — which is said to be a crucial step towards the development of self-powering portable electronics.
laptop typing Future Laptops Could Be Powered By Typing [RESEARCH]
Piezoelectricity, a phenomenon that was used in electric cigarette lighters was discovered in the 19th century. Similar to the way electric cigarette lighters use piezoelectric crystals to produce a high voltage electric current, laptops could also generate electric energy to self-charge themselves when buttons are pressed.
According to Dr. Madhu Bhaskaran:
The power of piezoelectrics could be integrated into running shoes to charge mobile phones, enable laptops to be powered through typing or even used to convert blood pressure into a power source for pacemakers – essentially creating an everlasting battery.
With the drive for alternative energy solutions, we need to find more efficient ways to power microchips, which are the building blocks of everyday technology like the smarter phone or faster computer.
The next key challenge will be amplifying the electrical energy generated by the piezoelectric materials to enable them to be integrated into low-cost, compact structures.
This study has been co-authored by Dr Bhaskaran with Dr Sharath Sriram, who is part of the Microplatforms Research Group, led by Professor Arnan Mitchell. Australian National University’s Dr Simon Ruffell also collaborated on the research. The study was published in Volume 21, Issue 12 of Advanced Functional Materials.
The drawback of this is that the piezelectric film is still not cost-effective to manufacture, but experts believe this dream will come true sooner rather than later.

Solar Tunnel To Power 4,000 Trains Annually

Solar Tunnel To Power 4,000 Trains Annually

Europe’s first “solar tunnel” is providing power to high-speed trains running between Paris and Amsterdam.
The 3.6-kilometer (2.2-mile) tunnel, built to protect trains from falling trees as they pass through an ancient forest near Antwerp, is covered with solar cells and could generate 3.3 MWh of electricity annually. Enfinity, the company behind the project, says that’s equivalent to the average annual consumption of nearly 1,000 homes. It also claims that the tunnel will decrease CO2 emissions by 2,400 tons per year.

“For train operators, it is the perfect way to cut their carbon footprints because you can use spaces that have no other economic value and the projects can be delivered within a year because they don’t attract the protests that wind power does,” Bart Van Renterghem, the UK head of Enfinity, told the Guardian.
The $22.9 million project uses 16,000 solar panels covering 50,000 square meters (roughly 538,000 square feet), which is about the size of eight football pitches. They will provide enough electricity to power 4,000 trains a year. The first of those trains left Antwerp on Monday, filled with commuters and students. The trains tap into the solar energy as they pass through the tunnel at 186 mph. The electricity also provides power for lighting, signals and other infrastructure.
“By using electricity generated on-site, we eliminate energy losses and transport costs,” Enfinity chief executive Steven De Tollenaere, told AFP.
Enfinity has said there had been plans afoot to introduce similar solar infrastructure in the UK but recent cuts to financial incentives would make the projects “unviable.”
“Apparently the UK Government is more concerned about the Treasury than the mid and long-term carbon reduction objectives that we have,” van Renerghem said. “Personally, I think it is short-sighted.”

Energy minister Greg Barker MP said in response: “We want to create a long-term platform for growth. Now that does mean that, in the short term, large-scale schemes aren’t going to get the sort of funding that we see in Belgium currently. There are a lot of exciting things in solar but we have got to think it through so that we get good value for the bill-payers as well as a great deal for the solar pioneers.”

 

How to Make Ceramics That Bend Without Breaking: Self-Deploying Medical Devices?

How to Make Ceramics That Bend Without Breaking: Self-Deploying Medical Devices?

Sep. 26, 2013 — Ceramics are not known for their flexibility: they tend to crack under stress. But researchers from MIT and Singapore have just found a way around that problem -- for very tiny objects, at least.

When subjected to a load, the molecular structure of the ceramic material studied by the MIT-Singapore team deforms rather than cracking. When heated, it then returns to its original shape.

The team has developed a way of making minuscule ceramic objects that are not only flexible, but also have a "memory" for shape: When bent and then heated, they return to their original shapes. The surprising discovery is reported this week in the journal Science, in a paper by MIT graduate student Alan Lai, professor Christopher Schuh, and two collaborators in Singapore.
Shape-memory materials, which can bend and then snap back to their original configurations in response to a temperature change, have been known since the 1950s, explains Schuh, the Danae and Vasilis Salapatas Professor of Metallurgy and head of MIT's Department of Materials Science and Engineering. "It's been known in metals, and some polymers," he says, "but not in ceramics."
In principle, the molecular structure of ceramics should make shape memory possible, he says -- but the materials' brittleness and propensity for cracking has been a hurdle. "The concept has been there, but it's never been realized," Schuh says. "That's why we were so excited."
The key to shape-memory ceramics, it turns out, was thinking small.
The team accomplished this in two key ways. First, they created tiny ceramic objects, invisible to the naked eye: "When you make things small, they are more resistant to cracking," Schuh says. Then, the researchers concentrated on making the individual crystal grains span the entire small-scale structure, removing the crystal-grain boundaries where cracks are most likely to occur.
Those tactics resulted in tiny samples of ceramic material -- samples with deformability equivalent to about 7 percent of their size. "Most things can only deform about 1 percent," Lai says, adding that normal ceramics can't even bend that much without cracking.
"Usually if you bend a ceramic by 1 percent, it will shatter," Schuh says. But these tiny filaments, with a diameter of just 1 micrometer -- one millionth of a meter -- can be bent by 7 to 8 percent repeatedly without any cracking, he says.
While a micrometer is pretty tiny by most standards, it's actually not so small in the world of nanotechnology. "It's large compared to a lot of what nanotech people work on," Lai says. As such, these materials could be important tools for those developing micro- and nanodevices, such as for biomedical applications. For example, shape-memory ceramics could be used as microactuators to trigger actions within such devices -- such as the release of drugs from tiny implants.
Compared to the materials currently used in microactuators, Schuh says, the strength of the ceramic would allow it to exert a stronger push in a microdevice. "Microactuation is something we think this might be very good for," he says, because the ceramic material has "the ability to push things with a lot of force -- the highest on record" for its size.
The ceramics used in this research were made of zirconia, but the same techniques should apply to other ceramic materials. Zirconia is "one of the most well-studied ceramics," Lai says, and is already widely used in engineering. It is also used in fuel cells, considered a promising means of providing power for cars, homes and even for the electric grid. While there would be no need for elasticity in such applications, the material's flexibility could make it more resistant to damage.
The material combines some of the best attributes of metals and ceramics, the researchers say: Metals have lower strength but are very deformable, while ceramics have much greater strength, but almost no ductility -- the ability to bend or stretch without breaking. The newly developed ceramics, Schuh says, have "ceramiclike strength, but metallike ductility."
In addition to Schuh and Lai, the work was carried out by Zehui Du and Chee Lip Gan of Nanyang Technological University in Singapore.
 

Nanoparticle Vaccine: Particles That Deliver Vaccines Directly to Mucosal Surfaces Could Defend Against Many Infectious Diseases

Nanoparticle Vaccine: Particles That Deliver Vaccines Directly to Mucosal Surfaces Could Defend Against Many Infectious Diseases

Sep. 25, 2013 — Many viruses and bacteria infect humans through mucosal surfaces, such as those in the lungs, gastrointestinal tract and reproductive tract. To help fight these pathogens, scientists are working on vaccines that can establish a front line of defense at mucosal surfaces.
Engineers have developed a new type of nanoparticle that protects the vaccine long enough to generate a strong immune response -- not only in the lungs, but also in mucosal surfaces far from the vaccination site, such as the gastrointestinal and reproductive tracts. (Credit: © ancroft / Fotolia)
Vaccines can be delivered to the lungs via an aerosol spray, but the lungs often clear away the vaccine before it can provoke an immune response. To overcome that, MIT engineers have developed a new type of nanoparticle that protects the vaccine long enough to generate a strong immune response -- not only in the lungs, but also in mucosal surfaces far from the vaccination site, such as the gastrointestinal and reproductive tracts.
Such vaccines could help protect against influenza and other respiratory viruses, or prevent sexually transmitted diseases such as HIV, herpes simplex virus and human papilloma virus, says Darrell Irvine, an MIT professor of materials science and engineering and biological engineering and the leader of the research team. He is also exploring use of the particles to deliver cancer vaccines.
"This is a good example of a project where the same technology can be applied in cancer and in infectious disease. It's a platform technology to deliver a vaccine of interest," says Irvine, who is a member of MIT's Koch Institute for Integrative Cancer Research and the Ragon Institute of Massachusetts General Hospital, MIT and Harvard University.
Irvine and colleagues describe the nanoparticle vaccine in the Sept. 25 issue of Science Translational Medicine. Lead authors of the paper are recent PhD recipient Adrienne Li and former MIT postdoc James Moon.
Sturdier vaccines
Only a handful of mucosal vaccines have been approved for human use; the best-known example is the Sabin polio vaccine, which is given orally and absorbed in the digestive tract. There is also a flu vaccine delivered by nasal spray, and mucosal vaccines against cholera, rotavirus and typhoid fever.
To create better ways of delivering such vaccines, Irvine and his colleagues built upon a nanoparticle they developed two years ago. The protein fragments that make up the vaccine are encased in a sphere made of several layers of lipids that are chemically "stapled" to one another, making the particles more durable inside the body.
"It's like going from a soap bubble to a rubber tire. You have something that's chemically much more resistant to disassembly," Irvine says.
This allows the particles to resist disintegration once they reach the lungs. With this sturdier packaging, the protein vaccine remains in the lungs long enough for immune cells lining the surface of the lungs to grab them and deliver them to T cells. Activating T cells is a critical step for the immune system to form a memory of the vaccine particles so it will be primed to respond again during an infection.
Stopping the spread of infection
In studies of mice, the researchers found that HIV or cancer antigens encapsulated in nanoparticles were taken up by immune cells much more successfully than vaccine delivered to the lungs or under the skin without being trapped in nanoparticles.
HIV does not infect mice, so to test the immune response generated by the vaccines, the researchers infected the mice with a version of the vaccinia virus that was engineered to produce the HIV protein delivered by the vaccine.
Mice vaccinated with nanoparticles were able to quickly contain the virus and prevent it from escaping the lungs. Vaccinia virus usually spreads to the ovaries soon after infection, but the researchers found that the vaccinia virus in the ovaries of mice vaccinated with nanoparticles was undetectable, while substantial viral concentrations were found in mice that received other forms of the vaccine.
Mice that received the nanoparticle vaccine lost a small amount of weight after infection but then fully recovered, whereas the viral challenge was 100 percent lethal to mice who received the non-nanoparticle vaccine.
"Giving the vaccine at the mucosal surface in the nanocapsule form allowed us to completely block that systemic infection," Irvine says.
The researchers also found a strong memory T cell presence at distant mucosal surfaces, including in the digestive and reproductive tracts. "An important caveat is that although immunity at distant mucus membranes following vaccination at one mucosal surface has been seen in humans as well, it's still being worked out whether the patterns seen in mice are fully reproduced in humans," Irvine says. "It might be that it's a different mucosal surface that gets stimulated from the lungs or from oral delivery in humans."
Tumor defense
The particles also hold promise for delivering cancer vaccines, which stimulate the body's own immune system to destroy tumors.
To test this, the researchers first implanted the mice with melanoma tumors that were engineered to express ovalbumin, a protein found in egg whites. Three days later, they vaccinated the mice with ovalbumin. They found that mice given the nanoparticle form of the vaccine completely rejected the tumors, while mice given the uncoated vaccine did not.
Further studies need to be done with more challenging tumor models, Irvine says. In the future, tests with vaccines targeted to proteins expressed by cancer cells would be necessary.
