Plasma scientists develop computer programs that could reduce the cost of microchips and stimulate American manufacturing      (via sciencedaily.com)     Original source 

Fashioned from the same element found in sand and covered by intricate patterns, microchips power smartphones, augment appliances and aid the operation of cars and airplanes. Now, scientists are developing computer simulation codes that will outperform current simulation techniques and aid the production of microchips using plasma, the electrically charged state of matter also used in fusion research. These codes could help increase the efficiency of the manufacturing process and potentially stimulate the renaissance of the chip industry in the United States.

Accelerating the discovery of single-molecule magnets with deep learning      (via sciencedaily.com)     Original source 

Single-molecule magnets (SMMs) are exciting materials. In a recent breakthrough, researchers have used deep learning to predict SMMs from 20,000 metal complexes. The predictions were made solely based on the crystal structures of these metal complexes, thus eliminating the need for time-consuming experiments and complex simulations. As a result, this method is expected to accelerate the development of functional materials, especially for high-density memory and quantum computing devices.

Bat 'nightclubs' may be the key to solving the next pandemic      (via sciencedaily.com)     Original source 

Researchers are studying how bats can carry deadly viruses, but not develop symptoms. They found that what happens during swarming behavior -- like social gatherings for bats -- may hold the key to understanding their viral tolerance and translate to human health in fighting off diseases like Ebola and COVID-19.

A new glue, potentially also for you      (via sciencedaily.com)     Original source 

Hydrogels are already used in clinical practice for the delivery of drugs, and as lenses, bone cement, wound dressings, 3D scaffolds in tissue engineering and other applications. However, bonding different hydrogel polymers to one another has remained a challenge; yet it could enable numerous new applications. Now, researchers have pioneered a new method that uses a thin film of chitosan, a fibrous sugar-based material derived from the processed outer skeletons of shellfish, to make different hydrogels instantaneously and strongly stick to each other. They used their approach to locally protect and cool tissues, seal vascular injuries, and prevent unwanted 'surgical adhesions' of internal body surfaces.

Giant Antarctic sea spiders reproductive mystery solved      (via sciencedaily.com)     Original source 

Instead of carrying the babies until they hatched, as in most species of sea spiders, one parent (likely the father) spent two days attaching the eggs to the rocky bottom where they developed for several months before hatching as tiny larvae.

Mystery solved: The oldest fossil reptile from the alps is an historical forgery      (via sciencedaily.com)     Original source 

Palaeontological analysis shows that a renowned fossil thought to show soft tissue preservation is in fact just paint. The fossil discovered in 1931 was thought to be an important specimen for understanding early reptile evolution. While not all of the celebrated fossil is a forgery, scientists urge caution in how the fossil is utilized in future.

New chip opens door to AI computing at light speed      (via sciencedaily.com)     Original source 

Engineers have developed a new chip that uses light waves, rather than electricity, to perform the complex math essential to training AI. The chip has the potential to radically accelerate the processing speed of computers while also reducing their energy consumption.

Ancient retroviruses played a key role in the evolution of vertebrate brains      (via sciencedaily.com)     Original source 

Researchers report that ancient viruses may be to thank for myelin -- and, by extension, our large, complex brains. The team found that a retrovirus-derived genetic element or 'retrotransposon' is essential for myelin production in mammals, amphibians, and fish. The gene sequence, which they dubbed 'RetroMyelin,' is likely a result of ancient viral infection, and comparisons of RetroMyelin in mammals, amphibians, and fish suggest that retroviral infection and genome-invasion events occurred separately in each of these groups.

Some Pre-Roman humans were buried with dogs, horses and other animals      (via sciencedaily.com)     Original source 

Some people from an ancient community in what is now northern Italy were interred with animals and animal parts from species such as dogs, horses and pigs. The reasons remain mysterious, but might indicate an enduring companion relationship between these humans and animals, or religious sacrificial practices, according to a new study.

By growing animal cells in rice grains, scientists dish up hybrid food      (via sciencedaily.com)     Original source 

From lab-grown chicken to cricket-derived protein, these innovative alternatives offer hope for a planet struggling with the environmental and ethical impacts of industrial agriculture. Now, scientists add a new recipe to the list -- cultured beef rice -- by growing animal muscle and fat cells inside rice grains. The method results in a nutritious and flavorful hybrid food that, once commercialized, could offer a more affordable protein alternative with a smaller carbon footprint.

Great apes playfully tease each other      (via sciencedaily.com)     Original source 

Babies playfully tease others as young as eight months of age. Since language is not required for this behavior, similar kinds of playful teasing might be present in non-human animals. Now cognitive biologists and primatologists have documented playful teasing in four species of great apes. Like joking behavior in humans, ape teasing is provocative, persistent, and includes elements of surprise and play. Because all four great ape species used playful teasing, it is likely that the prerequisites for humor evolved in the human lineage at least 13 million years ago.

The hidden rule for flight feathers -- and how it could reveal which dinosaurs could fly      (via sciencedaily.com)     Original source 

Scientists examined hundreds of birds in museum collections and discovered a suite of feather characteristics that all flying birds have in common. These 'rules' provide clues as to how the dinosaur ancestors of modern birds first evolved the ability to fly, and which dinosaurs were capable of flight.
