Bloodthirsty bedbugs have feasted on prey for 100 million years
Research sheds light on the evolutionary history of the bloodsucking bedbugs. The first species evolved at least as early as the Cretaceous, scientists say.

A rare, ancient case of bone cancer has been found in a turtle ancestor
A 240-million-year-old fossil reveals the oldest known case of bone cancer in an amniote, a group that includes mammals, birds and reptiles.

A CRISPR gene drive for mice is one step closer to reality
Researchers have made progress toward creating a gene drive for mice in the lab. Such genetic cut-and-paste machines have yet to be made for mammals.

A ghost gene leaves ocean mammals vulnerable to some pesticides
Manatees, dolphins and other warm-blooded marine animals can't break down organophosphates due to genetic mutations that occurred long ago.

Madagascar’s predators are probably vulnerable to toxic toads
The Asian common toad, an invasive species in Madagascar, produces a toxin in its skin that’s probably toxic to most of the island’s predators.

Why some mammal species don’t have descended testicles, but most do
New research studying genetic vestiges suggests that descended testicles are as ancient as the first placental mammal.

Malaysia is ground zero for the next malaria menace
With deforestation in Malaysia, monkeys and humans are getting closer — and mosquitoes are infecting humans with malaria from monkeys.

Green blood in lizards probably evolved four times
Pigment buildups that would cause jaundice in people are normal for some New Guinea skinks.

To understand the origins of pain, ask a flatworm
A danger-sensing protein responds to hydrogen peroxide in planarians, results that hint at the evolutionary origins of people’s pain sensing.

Ancient DNA bucks tale of how the horse was tamed
DNA from ancient horses reveals early domestication involved plenty of stallions.
