Disease Roundup
Scientists are looking at germs' genes to find their weaknesses.
DNA Roundup
DNA carries all of the information needed to make a complex organism. But can it also make crack-resistent eyeglasses?
Heart and Personality
New research suggests personality and heart disease aren't as intertwined as we thought.
Podcast
Underwater noise pollution, genes for alcoholism, PCBs may compromise vaccines, proof of dark matter, and uvulas in animals.
Podcast
The better way to commute, resetting your internal food clock, why we don't remember our dreams, fungi that live in plants, and the problem with some drug companies' patient headhunting practices.
Home Genetics Roundup
A government report says genetic tests offered for home use are often not reliable.

Testing the age of your organs, the reliability of home genetic tests, a medical use for radioactive scorpion venom, global warming may be irreversible, and the weather on Titan.
Aging Test
Your organs age at different rates. But how do you know how old they are?

Pregnancy Sickness
Mothers-to-be take heart: Morning sickness may have a good reason for existing.
Darwin’s Finches
The finches that Darwin discovered in the Galapagos are still yielding new data on evolution.

Primitive Ape-Man
Scientists have discovered one of our early apelike ancestors.
Fish Model Roundup
Nature has given some animals some pretty cool tricks, like the ability to regrow limbs and go without oxygen for months. Scientists think understanding those abilities might lead to medical advances for people.
Obesity Virus
It's well known that washing your hands will help you avoid catching colds. But could it also keep you from getting fat?
Laughter Origin
We've all heard that he who laughs last laughs best. But scientists are more interested in who laughed first.
Podcast
Spiders that eat their mates, why cloned animals get sick, some lesser known dangers of inbreeding, the origins of Jupiter's moons, and fish in see-through eggs.
Disease and Diversity
It's well known that inbred animals are more likely to inherit genetic diseases. But did you know that they are also more susceptible to infectious diseases?
