Published N-channel diamond field-effect transistor
(via sciencedaily.com) Original source A research team has developed an n-channel diamond MOSFET (metal-oxide-semiconductor field-effect transistor). The developed n-channel diamond MOSFET provides a key step toward CMOS (complementary metal-oxide-semiconductor: one of the most popular technologies in the computer chip) integrated circuits for harsh-environment- applications as well as the development of diamond power electronics.
Published Heat to blame for space pebble demise
(via sciencedaily.com) Original source The dust of comets fills the space between the planets, collectively called the zodiacal cloud. Still, severe breakdown has reduced that dust in size so much that it now scatters sunlight efficiently, causing the faint glow in the night sky known as the 'zodiacal light.' It was long thought that high-speed collisions pulverized the comet ejecta, but now a team of researchers reports that heat is to blame.
Published Decoding the plant world's complex biochemical communication networks
(via sciencedaily.com) Original source A research team has begun translating the complex molecular language of petunias. Their grammar and vocabulary are well hidden, however, within the countless proteins and other compounds that fill floral cells. Being rooted to the ground, plants can't run away from insects, pathogens or other threats to their survival. But plant scientists have long known that they do send warnings to each other via scent chemicals called volatile organic compounds.
Published AI can now detect COVID-19 in lung ultrasound images
(via sciencedaily.com) Original source Artificial intelligence can spot COVID-19 in lung ultrasound images much like facial recognition software can spot a face in a crowd, new research shows. The findings boost AI-driven medical diagnostics and bring health care professionals closer to being able to quickly diagnose patients with COVID-19 and other pulmonary diseases with algorithms that comb through ultrasound images to identify signs of disease.
Published Deep Earth electrical grid mystery solved
(via sciencedaily.com) Original source To 'breathe' in an environment without oxygen, bacteria in the ground beneath our feet depend upon a single family of proteins to transfer excess electrons, produced during the 'burning' of nutrients, to electric hairs called nanowires projecting from their surface.
Published Verifying the work of quantum computers
(via sciencedaily.com) Original source Researchers have invented a new method by which classical computers can measure the error rates of quantum machines without having to fully simulate them.
Published Quantum talk with magnetic disks
(via sciencedaily.com) Original source Quantum computers promise to tackle some of the most challenging problems facing humanity today. While much attention has been directed towards the computation of quantum information, the transduction of information within quantum networks is equally crucial in materializing the potential of this new technology. Addressing this need, a research team is now introducing a new approach for transducing quantum information: the team has manipulated quantum bits, so called qubits, by harnessing the magnetic field of magnons -- wave-like excitations in a magnetic material -- that occur within microscopic magnetic disks.
Published AI ethics are ignoring children, say researchers
(via sciencedaily.com) Original source Researchers have called for a more considered approach when embedding ethical principles in the development and governance of AI for children.
Published Across oceans and millennia: decoding the origin and history of the bottle gourd
(via sciencedaily.com) Original source Researchers have uncovered intriguing details about the origins and spread of the bottle gourd, one of the oldest domesticated crops. Their work unveils the genetic diversification and population history of this hard-shelled plant that was used to make bottles, instruments, and containers for over 10,000 years by ancient civilizations.
Published Powerful new AI can predict people's attitudes to vaccines
(via sciencedaily.com) Original source A powerful new tool in artificial intelligence is able to predict whether someone is willing to be vaccinated against COVID-19.
Published In flies, a single brain cell can drive multiple movements of the body
(via sciencedaily.com) Original source Motor neurons are the cells the brain uses to command muscles to act. Scientists typically thought of them as simple connections, much like the cables that link computers with their accessories. Now, in fly studies, researchers have discovered that single motor neurons can each direct an insect's body to move in far more complex ways than previously thought.
Published Brain-inspired wireless system to gather data from salt-sized sensors
(via sciencedaily.com) Original source In a new study, researchers describe a novel approach for a wireless communication network that can efficiently transmit, receive and decode data from thousands of microelectronic chips that are each no larger than a grain of salt.
Published Artificial nanofluidic synapses can store computational memory
(via sciencedaily.com) Original source In a step toward nanofluidic-based neuromorphic -- or brain-inspired -- computing, engineers have succeeded in executing a logic operation by connecting two chips that use ions, rather than electrons, to process data.
Published Researchers develop deep learning model to predict breast cancer
(via sciencedaily.com) Original source Researchers have developed a new, interpretable artificial intelligence (AI) model to predict 5-year breast cancer risk from mammograms, according to a new study.
Published Fairy circles: Plant water stress causes Namibia's gaps in grass
(via sciencedaily.com) Original source Namibia's legendary fairy circles are mysterious, circular, bald patches in the dry grasslands on the edge of the Namib Desert. Their formation has been researched for decades and has recently been the subject of much debate. With extensive fieldwork, researchers investigated how freshly germinated grass dies inside the fairy circle. Their results show that the grass withers due to a lack of water inside the fairy circle. The topsoil, comprised of the top 10 to 12 centimeters of the soil, acts as a kind of 'death zone' in which fresh grass cannot survive for long.
Published Tanks of the Triassic: New crocodile ancestor identified
(via sciencedaily.com) Original source Dinosaurs get all the glory. But aetosaurs, a heavily armored cousin of modern crocodiles, ruled the world before dinosaurs did. These tanks of the Triassic came in a variety of shapes and sizes before going extinct around 200 million years ago. Today, their fossils are found on every continent except Antarctica and Australia.
Published Backyard insect inspires invisibility devices, next gen tech
(via sciencedaily.com) Original source Leafhoppers, a common backyard insect, secrete and coat themselves in tiny mysterious particles that could provide both the inspiration and the instructions for next-generation technology, according to a new study. In a first, the team precisely replicated the complex geometry of these particles, called brochosomes, and elucidated a better understanding of how they absorb both visible and ultraviolet light.
Published Where quantum computers can score
(via sciencedaily.com) Original source The traveling salesman problem is considered a prime example of a combinatorial optimization problem. Now a team has shown that a certain class of such problems can actually be solved better and much faster with quantum computers than with conventional methods.
Published Genetic basis for the evolution of hair discovered in the clawed frog
(via sciencedaily.com) Original source The development of hair was of central importance for the evolution of mammals and thus also of humans. However, the evolutionary origin of the genetic program of hair was previously unknown. Researchers have now been able to show that important hair components and their genetic control have already evolved in amphibians. Human hair therefore shows unexpected similarities to the claws of clawed frogs.
Published Eyes open and toes out of water: How a giant water bug reached the island of Cyprus
(via sciencedaily.com) Original source A new visitor was reported on the coast of Cyprus, thanks to the growing power of citizen science. Researchers collected information and specimens through personal communication with amateur naturalists, but also through the internet, in order to compose the mosaic of repeated appearances of a giant water bug on the eastern shoreline of the island.
