Dialog / Bacteria may identify a virus without recognizing its DNA

When a virus enters a cell, its top priority is to replicate its genome rapidly, creating new viruses to infect elsewhere. The host has the opposite priority: to destroy the virus, ideally before it can do any harm. Biology ...

Phys.org / Flash droughts can pull 'alarming' amounts of moisture from the landscape and intensify wildfires

When catastrophic wildfires capture global headlines, such as the unprecedented blazes sweeping through southern Europe this summer or the devastating 2019–20 "Black Summer" in Australia, they are almost always preceded by ...
