Published Magnetoelectric material can reconnect severed nerves
(via sciencedaily.com) Original source Neuroengineers designed the first self-rectifying magnetoelectric material and showed it can not only precisely stimulate neurons remotely but also reconnect a broken sciatic nerve in a rat model.
Published Wireless, battery-free electronic 'stickers' gauge forces between touching objects
(via sciencedaily.com) Original source Engineers developed electronic 'stickers' that measure the force exerted by one object upon another. The force stickers are wireless, run without batteries and fit in tight spaces, making them versatile for a wide range of applications, from surgical robots to smart implants and inventory tracking.
Published Modular dam design could accelerate the adoption of renewable energy
(via sciencedaily.com) Original source Scientists have developed a new modular steel buttress dam system designed to resolve energy storage issues hindering the integration of renewable resources into the energy mix. The new modular steel buttress dam system facilitates the rapid construction of paired reservoir systems for grid-scale energy storage and generation using closed-loop pumped storage hydropower, cutting dam construction costs by one-third and reducing construction schedules by half.
Published Ginger pigment molecules found in fossil frogs
(via sciencedaily.com) Palaeontologists discover molecular evidence of phaeomelanin, the pigment that produces ginger coloration. Phaeomelanin is now toxic to animals – this discovery may be first step in understand its evolution.
Published Bumblebees drop to shake off Asian hornets
(via sciencedaily.com) Original source Bumblebees have a remarkably successful method for fighting off Asian hornets, new research shows.
Published Comfort with a smaller carbon footprint
(via sciencedaily.com) Original source Researchers have developed a data-driven AI algorithm for controlling the heating and cooling of an office building. The system does not require ambient sensors or specific knowledge of the building's rooms. During heating operations, the system was able to achieve energy savings of up to 30%, which can represent significant reductions to cost and environmental impact.
Published New type of tiny wasp comes with mysterious, cloud-like structures at ends of antennae
(via sciencedaily.com) Original source Fossil researchers have discovered a novel genus and species of tiny wasp with a mysterious, bulbous structure at the end of each antenna.
Published Hippos' prominent tusks and wide gaping mouths prevent efficient, grinding chewing
(via sciencedaily.com) Original source Hippos' huge tusks and wide gape restrict grinding jaw movements, making their chewing inefficient, according to a new study.
Published Scientists develop 3D printing method that shows promise for repairing brain injuries
(via sciencedaily.com) Original source Researchers have produced an engineered tissue representing a simplified cerebral cortex by 3D printing human stem cells. When implanted into mouse brain slices, the structures became integrated with the host tissue. The technique may ultimately be developed into tailored repairs to treat brain injuries.
Published Insect cyborgs: Towards precision movement
(via sciencedaily.com) Original source Insect cyborgs may sound like something straight out of the movies, but hybrid insect computer robots, as they are scientifically called, could pioneer a new future for robotics. It involves using electrical stimuli to control an insect’s movement. Now, an international research group has conducted a study on the relationship between electrical stimulation in stick insects' leg muscles and the resulting torque (the twisting force that causes the leg to move).
Published Unique voice print in parrots
(via sciencedaily.com) Original source Individual voice could help birds be recognized in a flock, no matter what they say.
Published Disaster-proofing sustainable neighborhoods requires thorough long-term planning
(via sciencedaily.com) Original source Engineers and scientists look at how thoughtful design can reduce a sustainably-designed neighborhood’s energy vulnerability during power disruptions, as well as which design characteristics are needed if and when local populations need to move to shelters. Researchers analyzed the design and energy characteristics of particular kinds of buildings and neighborhoods to assess their vulnerabilities and their access to alternative and renewable energy sources. The authors use several scenarios involving different lengths of power disruption to see which kind of response is most beneficial to the populations affected.
Published Metal-loving microbes could replace chemical processing of rare earths
(via sciencedaily.com) Original source Scientists have characterized the genome of a metal-loving bacteria with an affinity for rare earth elements. The research paves the way towards replacing the harsh chemical processing of these elements with a benign practice called biosorption.
Published Study on mysterious Amazon porcupine can help its protection
(via sciencedaily.com) Original source A recent study sheds new light on the elusive Roosmalens' dwarf porcupine, a poorly understood neotropical species. After 22 years of relative obscurity, this research uncovers vital information about its distribution, phylogenetics, and potential conservation threats, not only revealing its endemic presence in the Madeira biogeographical province but also expanding its known range in the southern Amazon.
Published Skin behind the ears and between the toes can host a collection of unhealthy microbes
(via sciencedaily.com) Original source Scrubbing behind the ears and between the toes may help keep the skin in those regions healthy, new research suggests. The microbiome, or the collection of microbes living on and in the human body, are known to play a role in human health and the skin is no different. A new study has shown that the composition of the skin microbiome varies across dry, moist and oily regions of the skin.
Published Solving a sticky, life-threatening problem
(via sciencedaily.com) Original source Researchers have zeroed in on C. auris' uncanny ability to stick to everything from skin to catheters and made a startling discovery: it uses a protein similar to that used by barnacles and mollusks.
Published Polyps as pixels: Innovative technique maps biochemistry of coral reefs
(via sciencedaily.com) Original source Using an innovative new approach to sampling corals, researchers are now able to create maps of coral biochemistry that reveal with unprecedented detail the distribution of compounds that are integral to the healthy functioning of reefs.
Published Wild Asian elephants display unique puzzle solving skills
(via sciencedaily.com) Original source A new study has documented the abilities of individual wild Asian elephants to access food by solving puzzles that unlocked storage boxes. It is the first research study to show that individual wild elephants have different willingness and abilities to problem solve in order to get food.
Published Researchers dynamically tune friction in graphene
(via sciencedaily.com) Original source The friction on a graphene surface can be dynamically tuned using external electric fields, according to researchers.
Published Boo to a goose -- new animal behaviour tech aims to save wildlife
(via sciencedaily.com) Original source Facial recognition software used to study the social behavior of individual Greylag Geese in Europe will soon be used to monitor one of the rarest geese in the world, the Cape Barren Goose in South Australia. The technology was used to assess how each bird responds to images of themselves, other flock mates or partners and researchers say it could be used by other scientists or in citizen science apps around the world to monitor and record endangered wildlife or even to promote the welfare of animals in captivity.
