  • A success for designer life

    Synthetic biologists are scientists who create custom organisms in the lab. Their efforts have just taken a big step forward. They have created the first lab-made yeast chromosome. The advance could lead to entirely synthetic organisms customized to produce food, fuel or medicine.
  • The nose knows a trillion scents

    There's a long-standing claim that people can identify 10,000 different odors. But a new study suggests that people can actually identify at least 10,000 times that many scents.

    Inflation is the idea that in the split-second after the Big Bang, the universe exploded into huge-ness. Although the hypothesis is 30 years old, evidence to confirm it had been lacking. Until now.
  • Laser tweezers grab nano bits

    An optical fiber, a bit of gold and a laser make up a new type of tweezers. Scientists may soon use it to pick up and move around individual viruses or proteins.
