Tokyo, Japan - Researchers from Tokyo Metropolitan University have studied the properties of mixtures of silicone-coated "magic sand", a popular kid's toy, and normal sand. Silicone-coated sand particles were found to interact with each other only, and not with other sand particles. The team discovered that adding silicone-coated sand beyond a certain threshold leads to an abrupt change in clustering and rigidity, a simple, useful way to potentially tune the flow of granular materials for industry.
The process of egg formation in fruit flies relies on physical phenomena analogous to the exchange of gases between balloons of different sizes, according to a study by MIT biologists and mathematicians.
New research published in two papers by UC San Diego scientists describes novel achievements designed to make the implementation of gene drives safer and more controllable. The new split drive and home-and-rescue systems address concerns about the release of gene drives in wild populations.
A University at Buffalo-led research team is a 3D printing method called stereolithography and jelly-like materials known as hydrogels to develop a 3D printing method that's 10-50 times faster than the industry standard. The team says its progress toward 3D-printed human tissue and organs -- biotechnology that could eventually save countless lives lost due to the shortage of donor organs.
Could cactus pear become a major crop like soybeans and corn in the near future, and help provide a biofuel source, as well as a sustainable food and forage crop? According to a recently published study, researchers from the University of Nevada, Reno believe the plant, with its high heat tolerance and low water use, may be able to provide fuel and food in places that previously haven't been able to grow sustainable crops.
Researchers at Indiana University School of Medicine have successfully reprogrammed a glial cell type in the central nervous system into new neurons to promote recovery after spinal cord injury--revealing an untapped potential to leverage the cell for regenerative medicine.
Canadian Scientists and Swiss Surgeons discover the cause of excess post-surgical scarring. The finding could improve recovery from abdominal and pelvic surgery. The research published in Science, was conducted in mice and shows the excess scarring is caused by macrophages. The researchers also discovered two ways to inhibit this natural response. Macrophages are also present in humans. The team hopes to move to trials on human cells, soon, and eventually clinical trials.
The gene for Huntington's disease was found nearly 40 years ago, yet there are no approved treatments. A new study shows the problem may lie with slowed protein assembly.
Studies of the microbiome in the human gut have largely overlooked non-bacterial microbes: viruses, protists, archaea and fungi. Now research in mice points to a significant role for fungi, called the mycobiome, in the intestine. "We showed that the gut mycobiome of healthy mice was shaped by the environment, including diet, and that it significantly correlated with metabolic outcomes," said Kent Willis, M.D.
A team of scientists from Geisinger and Tempus have found that artificial intelligence can predict risk of new atrial fibrillation (AF) and AF-related stroke.
