WISP computer has no battery, gets power wirelessly from radio waves. Lab accident leads to discovery of battery that lasts 400 times longer. Researchers at UC Irvine may have found a way to design a battery so it doesn’t lose its charge after years of use.
The researchers discovered that by using a gold nanowire in electrolyte gel rather than lithium, the battery could withstand 200,000 charging cycles and only lose five percent of its capacity. Lithium batteries are subject to some corrosion after consistently being depleted and recharged. Science based - How to modify the human eye to see into the ultraviolet and infrared bands?
There are a number of issues here.
Resolution Ok, so let's say you create a new kind of cone that's sensitive to UV. Scientists create metallic foam that shatters bullets. Engineers are developing new materials with the potential to offer unprecedented protection from bullets and crashes.
Take a new composite metal foam, that absorbs most of the kinetic energy of bullets or other projectiles. Researchers with North Carolina State and the US Army Research, Development and Engineering Center have combined multiple bullet-stopping materials into a single piece of armor. First transistors made entirely of nanocrystal 'inks' The transistor is the most fundamental building block of electronics, used to build circuits capable of amplifying electrical signals or switching them between the 0s and 1s at the heart of digital computation.
Transistor fabrication is a highly complex process, however, requiring high-temperature, high-vacuum equipment. Now, University of Pennsylvania engineers have shown a new approach for making these devices: sequentially depositing their components in the form of liquid nanocrystal "inks. " Their new study, published in Science, opens the door for electrical components to be built into flexible or wearable applications, as the lower-temperature process is compatible with a wide array of materials and can be applied to larger areas. Essence of stem cells found: Key ingredients protect, heal the brain. For years, stem cell-based therapies have promised myriad breakthroughs in healthcare—from cancer treatments and re-growing teeth to preventing brain damage and degeneration.
While some therapies have met with much more success than others, they all face the same challenge of working with live cells. This work can be tricky. Getting some types of cells can pose ethical issues; a patient’s immune system can attack those cells once they're used; and stem cells can sometimes go haywire and generate tumors. But for one promising stem cell therapy—one that thwarts brain damage—scientists may have found a way around the problems.
By extracting molecular bundles called microvesicles from stem cells, scientists can harness the same neuro-protective and healing properties seen with whole stem cell treatments. Those researchers, all based at the University of California, Irvine, began looking into microvesicles as a way to treat patients with brain cancer—particularly child patients. CGRO SSC >> ANTIMATTER CLOUDS AND FOUNTAIN DISCOVERED IN THE MILKY WAY. Scientists using data from an instrument on NASA Compton Gamma Ray Observatory (CGRO) have discovered two unexpected clouds of antimatter in the Milky Way Galaxy which scientists call antimatter annihilation radiation.
Scientists from Northwestern University, Evanston, IL, the Naval Research Laboratory (NRL), Washington, DC, and other institutions used CGRO Oriented Scintillation Spectrometer Experiment (OSSE) to make the discovery, which points to the existence of a hot fountain of gas filled with antimatter electrons rising from a region that surrounds the center of the Milky Way galaxy. The nature of the furious activity producing the hot antimatter-filled fountain is unclear, but could be related to massive star formation taking place near the large black hole at the center of the galaxy.
Other possibilities include winds from giant stars or black hole antimatter factories. Click images for larger views If you have a question about CGRO, please contact us via the Feedback form. The Trouble with Transporters. Scientists discover how to 'upload knowledge to your brain' How a MIT team made solar cells as thin as soap bubbles. Researchers at the Massachusetts Institute of Technology (MIT) have developed the thinnest and lightest solar cells ever made, which could eventually be used to power the next generation of personal electronics.
The process of creating the small, flexible cells – measured at a thickness of only 1.3 micrometers and a surface density of 3.6 grams per square meter – was described by MIT professor and associate innovation dean Vladimir Bulović along with researcher Annie Wang and doctoral student Joel Jean in the April edition of Organic Electronics. The scientists developed the organic cells by growing a parylene-C polymer substrate film in a vacuum, creating solar units that are comparable in their energy output to those utilizing a traditional glass design.
By growing the cell, substrate, and coating together in a lab in one process, development was streamlined and the cells end up being less exposed than if the components were created separately. It’s actually easy to force people to be evil. We've known for a long time that people will do terrible things under orders—like hurt strangers.
But why are we so easily persuaded to do things we wouldn't otherwise choose, even when nobody is holding guns to our heads? A new scientific experiment sheds light on this ancient ethical question. University College London neuroscientist Patrick Haggard and his colleagues wanted to measure what's happening in the human brain when ordered to do something, versus choosing to do something. In Current Biology, the researchers report on how they reenacted a famous twentieth century experiment to find out. New molecular scissors cut out lingering HIV—maybe once and for all. For the approximately 37 million people worldwide who are infected with HIV (human immunodeficiency virus), the newest cocktails of anti-retroviral drugs have come a long way in beating back the retrovirus and keeping an infection in check.
Still, those drugs are no cure. While the treatments snarl the viral assembly line and thwart new infectious particles from invading the body’s cells, HIV itself is still there, hunkered in the DNA of a patient’s genome until there’s an opportunity for a comeback—say, when a patient goes off their medication. As long as there’s lingering HIV, patients must keep taking the drugs, which cause side-effects, make for high prescription bills, and raise the threat of drug resistance. A metal that behaves like water: Researchers describe new behaviors of graphene. Graphene is going to change the world -- or so we've been told.
Since its discovery a decade ago, scientists and tech gurus have hailed graphene as the wonder material that could replace silicon in electronics, increase the efficiency of batteries, the durability and conductivity of touch screens and pave the way for cheap thermal electric energy, among many other things. It's one atom thick, stronger than steel, harder than diamond and one of the most conductive materials on earth. But, several challenges must be overcome before graphene products are brought to market. Scientists are still trying to understand the basic physics of this unique material. Is D-Wave’s quantum processor really 10⁸ times faster than a normal computer? We have been following D-Wave's claims about its quantum hardware at Ars for a number of years. Over that time, my impression has oscillated between skepticism, strong skepticism, and mild enthusiasm.
Back in November, D-Wave issued a press release that basically asked tech journalists to spray paint a finish line just behind their feet and break out a victory flag. This fully transparent solar cell could make every window and screen a power source (updated) Back in August 2014, researchers at Michigan State University created a fully transparent solar concentrator, which could turn any window or sheet of glass (like your smartphone’s screen) into a photovoltaic solar cell. Unlike other “transparent” solar cells that we’ve reported on in the past, this one really is transparent, as you can see in the photos throughout this story. According to Richard Lunt, who led the research at the time, the team was confident the transparent solar panels can be efficiently deployed in a wide range of settings, from “tall buildings with lots of windows or any kind of mobile device that demands high aesthetic quality like a phone or e-reader.”
Now Ubiquitous Energy, an MIT startup we first reported on in 2013, is getting closer to bringing its transparent solar panels to market. Lunt cofounded the company and remains assistant professor of chemical engineering and materials science at Michigan State University. For more, read How do solar cells work? In a brain, dissolvable electronics monitor health and then vanish. From the folds and crinkles of a living brain, a fleeting fleck of electronics smaller than a grain of rice can wirelessly relay critical health information and then gently fade away. The transient sensors, which can measure pressure, temperature, pH, motion, flow, and potentially specific biomolecules, stand to permanently improve patient care, researchers said. With a wireless, dissolving sensor, doctors could ditch the old versions that require tethering patients to medical equipment and performing invasive surgery to remove, which adds risks of infections and complications to already vulnerable patients.
Though the first version, reported in Nature, was designed for the brain and tested in the noggins of living rats, the authors think the sensors could be used in many tissues and organs for a variety of patients—from car crash victims with brain injuries to people with diabetes. A mathematician has proposed a way to create and manipulate gravity. Yesterday, the physics community got hyped-up over rumours that scientists might have finally detected gravitational waves - ripples in the curvature of spacetime predicted by Einstein 100 years ago - and that their observations could be coming to a peer-reviewed journal near you soon. So far, our understanding of how gravity affects the Universe has been limited to observations of natural gravitational fields created by distant stars and planets. In fact, gravity is the last of the four fundamental forces that humans haven't figured out how to produce and control. But now André Füzfa, a mathematician at the University of Namur in Belgium, has published a paper proposing a device that could do just that - albeit in tiny doses.
