Ultimate self-sacrifice: Bacteria activate unusual defense to evade viral attack
For billions of years, viruses and bacteria have been embroiled in an arms race. In response to constant attacks by viruses known as bacteriophages—more commonly called "phages"—bacteria evolve new ways to defend themselves. ...

How morphogens steer early brain development by guiding stem cell gene activity
Just a few weeks after conception, stem cells are already orchestrating the future structure of the human brain. A new Yale-led study shows that, early in development, molecular "traffic cops" known as morphogens regulate ...

How fruit flies' neurons spot tiny visual errors to keep them flying straight
When a fruit fly is navigating straight forward at high speed, why does it know that it's not straying off course? Because as long as the fly moves directly forward, the visual scene shifts from front to back in a near-perfect ...

Skin wounds in humans found to heal nearly three times slower than those in other primates
A team of evolutionary scientists, dermatologists and wildlife specialists affiliated with several institutions in Japan, Kenya and France has found that human skin wounds take nearly three times as long to heal as they do ...
Discovery of histidine-ADP-ribose molecule reveals new bacterial immune strategy
A research team has uncovered a previously unknown type of immune signaling molecule—a novel compound combining histidine and ADP-ribose—produced by bacteria's Thoeris II defense system in response to viral infection. ...
