Scientists discover migration-mediated mechanism enabling bacteria-virus coexistence
来源: Phys.org - latest science and technology news stories · 发布于
Bacteria and the viruses that infect them—known as phages—coexist in soils, oceans and living organisms. Scientists have long thought this coexistence reflects a microscopic version of an evolutionary arms race: As parasites and hosts continually adapt to one another, both evolve
Bacteria and the viruses that infect them—known as phages—coexist in soils, oceans and living organisms. Scientists have long thought this coexistence reflects a microscopic version of an evolutionary arms race: As parasites and hosts continually adapt to one another, both evolve ways to survive. But a joint study by researchers at the University of Maryland and the University of Exeter shows different pathways to coexistence.

Scientists discover a bizarre Jurassic “squid” unlike anything ever seen
Scientists have identified the “fattest” belemnite ever discovered, a bizarre, barrel-shaped squid relative that lived in Wyoming’s ancient seas 160 million years ago. The exceptionally rare fossils reveal a creature unlike anything previously known, potentially a predator of sma

Scientists find a way to fight Alzheimer’s brain damage without removing toxic tau
Scientists have found a promising way to protect the brain from Alzheimer’s-related damage by blocking immune cells that contribute to the destruction of neurons. In mice, the treatment preserved roughly 40% more tissue in memory centers and improved memory, even without removing
