Brain Gain
The brain constantly sprouts new neurons, a recently discovered phenomenon that neuroscientists and drugmakers are working to understand and harness.
-
Past Impressions
New research sheds light on the century-old concept of transference, a mental process in which people re-experience past relationships in new interactions.
- Astronomy
Big Broadcast
A record-breaking radio burst from the sun last Dec. 6 temporarily overwhelmed scores of GPS receivers, highlighting the hazard of radio storms on Earth.
- Tech
Powering the Revolution
Sensors and other electronic devices that can scavenge energy could open a new realm for technology.
- Ecosystems
Slime Dwellers
The health of corals, and their adaptability in the face of adversity, may rest largely on the microbes they recruit into a slime that coats their surfaces.
- Tech
Reaching for Rays
Harnessing the sun's rays cheaply and efficiently could address the planet's energy needs.
- Health & Medicine
Dangerous History
The genome of the TB bacterium has small but significant pockets of diversity, giving scientists new targets for preventing and treating the disease.
- Physics
Spinning into Control
High-speed flywheels could replace batteries in hybrid vehicles and help make the electrical grid more reliable.
-
Our Microbes, Ourselves
Trillions of microbes live in the human gut and skin, and they may be essential to health.
- Animals
Egg Shell Game
Birds apparently cheat chance when it comes to laying eggs that contain sons or daughters.
- Physics
The Hunt for Antihelium
Scientists have been searching about 30 years for a single nucleus of helium made from antimatter, and although the discovery would imply that whole antimatter galaxies exist, the researchers' time could be running out.
- Math
Sensor Sensibility
Networks of tiny computerized sensors that adjust their function as needed may soon pervade our environment.
