From Dark Matter to Light
Recent surveys of the shapes, colors, and masses of galaxies have put a new focus on the nitty-gritty of galaxy formation—the complicated physics of the interaction of gas.

Road to Eureka!
Researchers are beginning to identify neural components of insightful problem solving, though no scientific consensus exists on how the brain mediates "light-bulb" or "Aha!" moments.

The Next Ocean
Increasing carbon dioxide in the air is changing the pH of the ocean, which could mean very different communities of sea creatures.

Beyond Blood
Bloodless MRI seeks a more direct window into the working brain than conventional techniques.
- Paleontology
Twice upon a Time
New fossil finds suggest that the complex features of mammals originated earlier than previously thought and might even have evolved independently in different mammalian lineages.

Rotten Remedy
The gas well-known for its smell of rotten eggs is, recent studies show, a ubiquitous concoction in the body. New studies suggest that the hydrogen sulfide occurring naturally inside us can be both friend and enemy to our health.

Nurturing Our Microbes
Nurturing the microbes living in the human body can pay dividends—from shortening the length of colds to fighting obesity and osteoporosis.

Micromanagers
Some scientists believe the human brain is the creation of RNA. Only noncoding RNAs are plentiful, and powerful enough to handle the billions of complex interactions the brain faces every day.

Jelly Propulsion
Jellyfish have been swimming the seas for at least 550 million years, and research is now revealing how the challenges of moving in fluid have shaped the creatures' evolution.

Energy in Motion
The molecular machines of living cells harvest energy out of randomness, and scientists are learning how to do the same with artificial molecules.

Extreme Measures
Physicists use atom interferometry to measure gravity and other forces with unrivaled precision, and the technique could potentially guide airplanes and uncover buried caches of oil and diamonds.

Weighty Evidence
Connections between the family of insulin hormones and cancer have been suspected for more than 2 decades, and today, drug companies are testing anticancer drugs based on the actions of an insulin cousin.
