Move Over Solar Panels, Nanotubes Are Coming

Phys.org – Physicists have discovered a novel kind of nanotube that generates current in the presence of light. Devices such as optical sensors and infrared imaging chips are likely applications, which could be useful in fields such as automated transport and astronomy. In future, if the effect can be magnified and the technology scaled up, it could lead to high-efficiency solar power devices.

Working with an international team of physicists, University of Tokyo Professor Yoshihiro Iwasa was exploring possible functions of a special semiconductor nanotube when he had a lightbulb moment. He took this proverbial lightbulb (which was in reality a laser) and shone it on the nanotube to discover something enlightening. Certain wavelengths and intensities of light induced a current in the sample—this is called the photovoltaic effect. There are several photovoltaic materials, but the nature and behavior of this nanotube is cause for excitement.

“Essentially our research material generates electricity like solar panels, but in a different way,” said Iwasa. “Together with Dr. Yijin Zhang from the Max Planck Institute for Solid State Research in Germany, we demonstrated for the first time nanomaterials could overcome an obstacle that will soon limit current solar technology. For now solar panels are as good as they can be, but our technology could improve upon that.” | go to source

Gray Matter Phases Targeted by

Tech Explorist – Yale scientists now have come up with a more accurate way to help classify phases of matter.

Understanding the complexities of these phases could open leaps forward in quantum computing and materials science. A portion of these phases could be utilized as quantum hard drives that will store quantum information. That is the reason researchers are effectively looking for new ways to deal with describing and characterize them….

Dua said, “Topological phases represent an important class of phases of matter. Their study and methods for diagnostics are important, and identifying the right diagnostic tools is fundamental.”

The findings appear in a recent study published in the journal Physical Review Letters and a follow-up work published in Physical Review B. | go to source

Fecal transplants may be best answer to antibiotic-resistant bacteria

Science Daily – Transplanting human donor fecal microbiota into the colon of a patient infected with Clostridiodes difficile (C. diff) may be the best treatment for those not helped by C. diff targeted antibiotics, according to an article in the Journal of the American Osteopathic Association.  C. diff is the most common healthcare-acquired infection in the United States. It affects nearly half a million patients each year and becomes a recurring infection for nearly a third of them. If untreated, C. diff can lead to sepsis and death. | go to source

Babies Get Two Paths, Fix the Wall or BE the Wall – The Life of Aphids

Science News – Colonies of tiny Nipponaphis monzeni aphids in eastern Asia use their own young as part repair crew, part repair goo. The tiny fluffs of juvenile insects end up dying after gushing white glop from their bodies to repair a hole in the wall protecting their colony in Asian winter hazel trees. New details of this patching chemistry suggest that these doomed young aphids are a colony’s version of immune system cells, researchers report April 15 in the Proceedings of the National Academy of Sciences. | go to source

Carbon Buildup in the Atmosphere Heightened with Melting Permafrost

Nature – Current models of greenhouse-gas release and climate assume that permafrost thaws gradually from the surface downwards. Deeper layers of organic matter are exposed over decades or even centuries, and some models are beginning to track these slow changes.

But models are ignoring an even more troubling problem. Frozen soil doesn’t just lock up carbon — it physically holds the landscape together. Across the Arctic and Boreal regions, permafrost is collapsing suddenly as pockets of ice within it melt. Instead of a few centimetres of soil thawing each year, several metres of soil can become destabilized within days or weeks. The land can sink and be inundated by swelling lakes and wetlands | go to source

Drone Steals Insect’s Wing Designs, Offers Insect No IP Compensation

Futurity –  “Our drone design was inspired by the wings and flight patterns of insects,” says Xiumin Diao, an assistant professor in the School of Engineering Technology at Purdue University. “We created a drone design with automatic folding arms that can make in-flight adjustments.” Diao says the design provides drones with improved stability in windy conditions because the folding arms can move and change the center of gravity of the device during flight. He says the design also makes drones more energy efficient because the movable-arm technology allows for the use of the full range of rotor thrust. | go to source

Mouse Brains Might Prove Overeating Is LITERALLY ALL in the Mind- LITERALLY

Discover Magazine – Now, a new discovery by a team of scientists at the University of North Carolina (UNC) School of Medicine may help explain why so many of us can’t resist polishing off a jumbo bag of chips or a carton of ice cream in one sitting – even if we know it’s not a good idea.  A new paper published this week in Neuron, explains that a specific brain circuit found in mammal brains seems to be involved in our urge to overeat tasty, calorie rich food. The researchers think this brain circuit essentially overrides the signals that our body and brain send to tell us to stop eating — and instead drives us to keep gorging after we’re full, consuming extra calories in the process. | go to source

Printing Living Cells to Replace Knees and Hips, That Dream Just Got a Boost

3ders.org –   “We’ve reached the point where we are able to create medical products, such as knee implants, by printing living cells,” says Rohan Shirwaiker, corresponding author of a paper on the work and an associate professor in NC State’s Edward P. Fitts Department of Industrial & Systems Engineering.  “We’ve now developed a technique, called ultrasound-assisted biofabrication (UAB), which allows us to align cells in a three-dimensional matrix during the bioprinting process. This allows us to create a knee meniscus, for example, that is more similar to a patient’s original meniscus. To date, we’ve been able to align cells for a range of engineered musculoskeletal tissues.” | go to source

If I Can Read Your Mind, I Can Synthesize Speech Better, and I’m the Brain Machine That Can Do It

CNET – A new technique could go a long way toward transforming brain activity into synthesized speech to truly restore the gift of gab to those who’ve lost the ability to talk.  Neuroscientists at UC San Francisco have created a brain-machine interface that interprets signals from the brain’s speech center via a novel two-step process. Instead of trying to translate brain activity directly into sounds, the researchers convert the neural signals into the movements a person’s vocal tract uses to create those sounds digitally.  | go to source
