Southern birds may be moving into your winter backyard
A warming climate is letting warm-adapted birds live farther north in winter, a new study finds.
- Paleontology
Stegosaurus landed a low blow in dino brawl
During a dinosaur scuffle 147 million years ago, a stegosaurus whipped an allosaurus in the crotch.
- Humans
Oldest human DNA narrows time of Neandertal hookups
A 45,000-year-old Siberian bone provides genetic clues about the timing of interbreeding between ancient humans and Neandertals.
- Paleontology
Mystery fossils belonged to giant ostrichlike dinosaur
Two recently found skeletons reveal that Deinocheirus, first discovered 50 years ago, was the largest-known dinosaur of its kind.
- Environment
Engineered plants demolish toxic waste
With help from bacteria, plants could one day clean up polluted sites.
- Humans
Anglo-Saxons left language, but maybe not genes to modern Britons
Modern Britons may be more closely related to Britain’s indigenous people than they are to the Anglo-Saxons, a new genetic analysis finds.
- Genetics
Camels’ number of humps may affect their fat storage
The number of humps camels and alpacas have may play a role in how well they store and break down fat.
- Genetics
Gene variant helps dog evade muscular dystrophy
A dog that has a mutation causing muscular dystrophy has another genetic variant that appears to counteract the disease.
- Animals

- Microbes
Microbes can redeem themselves to fight disease
With some genetic engineering, bacteria can morph from bad to good and help attack invading cancer cells.
- Animals
Hearing awful or great singing changes birds’ choice
A male bird’s serenade inspires reactions that depend on the quality of songs a female has been listening to.
