Bubbles may underlie trauma’s brain injury
Many soldiers and accident victims sustain traumatic brain injury that can affect memory, thinking and body movements. New research now studies whether tiny bubbles caused by pressure waves may trigger that damage.

New gene resists our last-ditch drug
Antibiotic resistance continues to grow. Now, scientists have found a tiny loop of DNA that resists a drug doctors use as a last line of defense.

As big animals poop out
Whales move nutrients from deep ocean to surface waters. From there, nutrients move to land and fertilize continents. But the system is in trouble.

Expert panel approves human gene editing
Scientists have recently been reporting big advances in the ability to tweak the genes of living organisms, including people. But some question the ethics of doing that. A panel of experts now says such research can go ahead — with one major exception.

Banana threat: Attack of the clones
Researchers find that disease-causing fungi — all clones of one another — will continue to infect banana plants unless new steps are taken to stop their spread.

Scientists identify plankton from space
Plankton are often too tiny for our eyes to see. But when huge numbers bloom at once, they now can be ID’d from space, a new study shows.

Predatory dinos were truly big-mouths
Large meat-eating dinosaurs could open their mouths wide to grab big prey. Vegetarians would have had a more limited gape, a new study suggests.
