Guardian Science Correspondent NIcola Davis reports that a nerve-cooling implant could offer pain relief alternative to opioids.
The team behind the device at Northwestern University in Illinois say it could bring benefits for management of acute pain such as that experienced after amputations, nerve grafts or spinal decompression surgeries.
Cancer patients are testing a drug made from antibodies designed from the ground up on a computer in Israel and “programmed” by the inventor to “decide” whether cells surrounding tumors are good or bad. If the study underway in Australia goes according to plan, these antibodies will target cells that help the tumor while boosting the abilities of cells that inhibit cancer growth. Their inventor, Prof. Yanay Ofran, said that antibody treatments have traditionally been based on human or animal antibodies... making antibodies from scratch on a computer and then making them from amino acids removes previous limitations... https://israeltrade.org.au/2022/11/23/australian-cancer-patients-te
The recipe for mammalian life is simple: take an egg, add sperm and wait. But two new papers demonstrate that there’s another way. Under the right conditions, stem cells can divide and self-organize into an embryo. In studies published in Cell and Nature recently, two groups report that they have grown synthetic mouse embryos for 8.5 days, longer than ever before. The embryos developed distinct organs — a beating heart, a gut tube and even neural folds.Research is being conducted at University of Cambridge, UK, and the California Institute of Technology in Pasadena.
