Reversing osteoporosis . . . in mice

A molecule promoting blood vessel growth in bone can create an environment suitable for bone-building formation, representing a potential target for new drugs to treat osteoporosis and fractures, according to new research by Weill Cornell Medicine scientists. The findings, published May 21 in Nature Medicine, show that a substance, which is best known for spurring nerve

Underwater exploration gets its own battery free sensing system

Submerged system uses the vibration of “piezoelectric” materials to generate power and send and receive data. To investigate the vastly unexplored oceans covering most our planet, researchers aim to build a submerged network of interconnected sensors that send data to the surface — an underwater “internet of things.” But how to supply constant power to

Nanomachines power a color changing chameleon skin for camouflage and displays

Researchers have developed artificial ‘chameleon skin’ that changes colour when exposed to light and could be used in applications such as active camouflage and large-scale dynamic displays. The material, developed by researchers from the University of Cambridge, is made of tiny particles of gold coated in a polymer shell, and then squeezed into microdroplets of

Paving the way for fully untethered soft robots with a self folding robot

3D-printed active hinges change shape in response to heat The majority of soft robots today rely on external power and control, keeping them tethered to off-board systems or rigged with hard components. Now, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and Caltech have developed soft robotic systems, inspired by origami, that

Fuel cells that use ammonia instead of hydrogen

Team of UD engineers pushes cost-effective fuel cell technology forward Fuel cells are pollution-free power sources that convert chemical energy to electricity with high efficiency and zero emissions. Fuel cell cars, trucks, and buses would allow people to travel long distances with convenient refueling and less of a carbon footprint. Researchers at the University of

A mysterious ocean algae scarcity could have enormous ramifications for the ocean’s food webs

A globally important ocean algae is mysteriously scarce in one of the most productive regions of the Atlantic Ocean, according to a new paper in Deep Sea Research I. A massive dataset has revealed patterns in the regions where Atlantic coccolithophores live, illuminating the inner workings of the ocean carbon cycle and raising new questions. “Understanding these

An inexpensive rechargeable manganese dioxide zinc battery could challenge lithium-ion dominance

A new rechargeable high voltage manganese dioxide zinc battery, exceeding the 2 V barrier in aqueous zinc chemistry, is the latest invention by City College of New York researchers. With a voltage of 2.45-2.8V, the alkaline MnO2|Zn battery, developed by Dr. Gautam G. Yadav and his group in the CCNY-based CUNY Energy Institute, could break the long dominance of

Expanding the microbiomes of koalas so they can eat a wider range of eucalypts to survive

Poo transplants are helping expand koala microbiomes, allowing the marsupials to eat a wider range of eucalypts and possibly survive habitat loss. A study featuring a University of Queensland researcher, built on extensive research conducted at Western Sydney University, has analysed and altered microbes in koalas’ guts, finding that a faecal transplant may influence what
