Axing molecular zombies may slow aging
Killing off dormant cells slows the decline of mice genetically engineered to grow old fast.
- Life
Nearness key in microbe DNA swaps
Close quarters, like those inside the human body, are the most important factor in determining how often bacteria pick up one another’s genes.

Python’s heart-restoring elixir works in mice
A chemical brew used by snakes to build cardiac muscle could have medical applications.
- Life
Giant dinosaurs may have migrated
Evidence in teeth suggests that sauropods sought greener pastures in dry North American summers.

Infected bats can recover . . . with lots of help
Researchers reported new data today confirming that with enough coddling, many heavily infected bats can recover. The rub: These scientists also pointed out that there really aren’t sufficient resources to save more than a handful this way.
- Life
Cause confirmed in bat scourge
White-nose syndrome has devastated bat population in eastern North America.
- Life
Gut bacteria linked to MS
Gut bacteria appear to play a role in initiating multiple sclerosis in mice.

Gene makes some pilots get rusty faster
A common DNA variant affects the pace of age-related decline in performance on skilled tasks like flying a plane.
- Life
Cycads not ‘living fossils’
Though ancient, today’s representatives of the plant group date back to a common ancestor that lived not all that long ago.
- Life
Live long, pass it on
A tendency for a lengthy life can be inherited for several generations, even when offspring no longer have the genes for it.

Stopping a real-life ‘Contagion’
An antibody treatment fends off the lethal Hendra virus in monkeys and may also work against the equally dangerous Nipah virus.
