Researchers induced a hibernation-like state in mice by using ultrasound to stimulate the hypothalamus preoptic area in the brain, which helps to regulate body temperature and metabolism. The findings show the first noninvasive and safe method to induce such a state; a similar condition has been previously proposed for spaceflight or for patients with life-threatening health conditions.

Researchers from Rice University have created drug-filled microparticles that can be engineered to degrade and release their therapeutic cargo days or weeks after administration. By combining multiple microparticles with different degradation times into a single injection, the researchers could develop a drug formulation that delivers many doses over time.

NIH researchers found that a gel made from the seeds of a South American palm tree entraps SARS-CoV-2 and the protein the virus uses to enter cells, preventing the virus from infecting cells in laboratory cultures. Their study is in Scientific Reports. Source: Eunice Kennedy Shriver National Institute of Child Health and Human Development.

Tissue engineering research has uncovered that a skin cell type could be a new therapeutic target to accelerate the healing of burns and possibly other wounds.

Automation uncovers combinations of amino acids that feed two bacterial species and could tell us much more about the 90% of bacteria that humans have hardly studied. An artificial intelligence system enables robots to conduct autonomous scientific experiments -- as many as 10,000 per day -- potentially driving a drastic leap forward in the pace of discovery in areas from medicine to agriculture to environmental science.

Engineers have developed a stretchable ultrasonic array capable of serial, non-invasive, three-dimensional imaging of tissues as deep as four centimeters below the surface of human skin, at a spatial resolution of 0.5 millimeters. This new method provides a non-invasive, longer-term alternative to current methods, with improved penetration depth. Source: University of California - San Diego/Science Daily

Researchers built a motor that could operate a robotic device made from non-magnetic materials and was powered by the magnetic field produced by the MRI.
