Scientists Say: Ectoparasite
Many people think of parasites as organisms that live inside their hosts. But some of them can be found on the outside instead.

Ancient jaw suggests humans left Africa earlier than thought
A fossil jaw found in a cave in Israel is at least 177,000 years old. The scientists who found it think it shows humans left Africa much earlier than thought.

En route to Mars, astronauts may face big health risks
Going into space brings the thrill of a new frontier — and risks that scientists are racing to understand, from radiation to isolation.

Yuck! Bedbug poop leaves lingering health risks
Chemical residues left by bedbugs can persist, even when the pests have been eradicated. This may explain lingering allergic symptoms in cleaned up homes, a new study concludes.

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.

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.
