Can DNA editing save endangered species?
Scientists may be able to help endangered species by changing the genes of a whole population of wild animals. But some question whether that is wise.

Human waste could power plastic-making in space
Someday recycled urine and exhaled breath could feed specially engineered yeast to make plastics and other useful chemicals on long space missions.

Human cells form the basis of this artificial eye
Real or fake — you be the judge. Human cells were used to create this test bed for studying both the eye and eye-disease therapies.

Defining a dinosaur is now far harder
New fossil finds are making it difficult to say for certain what makes dinosaurs unique.

Fish get pooped living in polluted water
Living in polluted water can tire fish out, a new study finds. This can make it harder for them to find food and avoid being eaten, themselves, by predators.
- Animals
Scientists Say: Zooplankton
These plankton are tiny, but don’t let that fool you. They are predators, too.

Hairy nanoparticles put viruses in a deadly embrace
Current drugs can’t stop viruses for good. But newly developed hairy nanoparticles just might. They surround and put pressure on the viruses, which ultimately destroys them.
- Microbes
Most Americans would welcome a microbial E.T.
People are more likely to welcome than be scared by new evidence pointing to extraterrestrial life, Americans report — at least if the E.T.’s are tiny.

Scientists Say: Triclosan
This chemical is known for its bacteria-killing skills. But its use can also promote the development of dangerous, antibiotic-resistant bacteria.

Woodpecker brains host protein linked with human brain damage
Woodpeckers peck with a force great enough to give people concussions. Now a study shows that birds, too, may suffer some brain damage.

Unlike adults, teens don’t perform better when the stakes are high
Adults tend to do better on tasks that have bigger rewards. Not teens. This difference might have to do with the rewiring of the brain during adolescence, new data suggest.

Rising carbon dioxide could leave tiny lake dwellers defenseless
Rising carbon dioxide in freshwater lakes may change how predators and prey interact.
