Why mammals like elephants and armadillos might get drunk easily
Differences in a gene for breaking down alcohol could help explain which mammals get tipsy.

With a litter of tactics, scientists work to tame cat allergies
New research may reduce the allergen levels of house cats or make people less reactive to our feline friends.

Some dog breeds may have trouble breathing because of a mutated gene
Norwich terriers don’t have flat snouts, but can suffer the same wheezing as bulldogs. It turns out that a gene mutation tied to swelling could be to blame.
- Genetics
Tweaking one gene with CRISPR switched the way a snail shell spirals
The first gene-edited snails confirm which gene is responsible for the direction of the shell’s spiral.

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.

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.
- Animals
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.

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.

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