New view reveals how DNA fits into cell
A new technique allows scientists to map the 3-D structure of the entire human genome.
- Life
Monkey moms and babies communicate from the start
Macaque mothers and infants engage in emotional interactions similar to those of human moms and their babies, a new study suggests.
- Chemistry
Nobel Prize in chemistry commends finding and use of green fluorescent protein
One researcher is awarded for discovering the protein that helps jellyfish glow and two for making the protein into a crucial tool for biologists.
- Health & Medicine
Pigs use mirrors
After some time to play around with a mirror, pigs figure out what to do when they glimpse a reflection of food.

Nobel in medicine honors discoveries of telomeres and telomerase
Three scientists share the Nobel Prize in Physiology or Medicine for the discovery of telomeres, which protect the ends of chromosomes, and the enzyme telomerase, which adds the structures to the ends of chromosomes.
- Chemistry
Flowerless plants make fancy amber
A new analysis suggests that ancient seed plants made a version of the fossilized resin credited to more modern relatives
- Life
Mitochondria behind life span extension
Study in flies suggests low-protein diet works through power-producing organelles.
- Chemistry
Earth’s ‘boring billion’ years blamed on sulfur-loving microbes
A new study suggests these organisms could have kept oxygen levels low and waters toxic, stalling the evolution of complex life.
- Paleontology
Parasite may have felled a mighty T. rex
An infection known to afflict modern birds may have led to starvation in several dinosaurs.
