There are a great many ways to influence cellular metabolism to modestly slow the pace of aging, but few of them are of lll that much interest from a practical point of view, as a basis for therapies that might meaningfully extend human life spans. If an approach involves improvements […]

Biological sensors developed by MIT spinout Glympse Bio could help clinicians make decisions for individual patients. In the fight against severe diseases like cancer, patients often endure a discomforting, weekslong gap between when treatment begins and when doctors can tell if it’s working. The problem often stems from an inability […]

Near-infrared hyperspectral imaging combined with machine learning can visualize tumors in deep tissue and covered by a mucosal layer, scientists show Gastrointestinal stromal tumors are tumors of the digestive tract that grow underneath the mucus layer covering our organs. Because they are deep inside the tissue, these “submucosal tumors” are […]

ETH researchers have found a gene mutation that causes the sperm of boars to immobilize. Their discovery will help pig breeders to exclude animals with this genetic defect from breeding in future. In pig farming, natural mating between a boar and a sow has become rare. It is much more […]

Researchers from Karolinska Institutet and Gothenburg University have investigated a potential new drug target for the rare genetic disorder Hutchinson-Gilford progeria syndrome that causes accelerated aging in children. The findings in mice are published in the scientific journal eLife and may aid in the development of more effective treatments for […]
