Jupiter’s long-lasting storm
Most studies of Jupiter’s centuries-old Great Red Spot suggest this giant storm should have petered out after a few decades. A new study traces the storm’s staying power to the vertical movement of its gases.

The data flood
Mountains of data drive advances in science, medicine and other fields. Here’s how they might affect you.

Explainer: Understanding the size of data
Data are beginning to accumulate in quantities of mammoth size.

Human ancestors threw spears
Who threw first? Scientists had long believed that ancient people who lived 80,000 years ago were the first to throw spears with stone tips. But the discovery of 279,000-year-old stone spear tips in Ethiopia pushes that date back, and suggests prehuman species hunted with spears too.
- Science & Society
Bigger groups make better tools
As the size of a population grows, so too does its ability to quickly create clever new tools. Lab experiments suggest that connections between people give rise to the new creations.

New problem linked to ‘jet lag’
The body’s internal clock can be thrown off when people alter their day and night routines. That mix-up may lead to a buildup of immune cells that can cause inflammation, according to a new study on mice.

Mice on steroids
A new mouse study suggests the effects of steroids can last at least months. That’s long after most sporting authorities would be able to identify signs of doping in athletes.

Energy companies triggered quakes, study says
Injecting carbon dioxide underground seems like a good way to slow down global warming. A new study shows, however, that the process could trigger earthquakes.

Seeing without light
Many people report seeing their own hands moving in the dark, a new study finds. In these people, brain areas responsible for motion appear to fool vision centers into seeing what they would have — if there had been enough light to do so.

Sleeping brains take a bath
During waking hours, litter builds up in the spaces between brain cells. A new study shows that during sleep, fluid from the brain and spinal cord takes out this trash.

Water helped erect Iceland’s lava towers
Science pointed the way to understanding why these curious natural pillars form.

One eye, 3-D
Most scientists think people need two eyes to see a flat image or movie in three dimensions. However, a new study suggests seeing in 3-D with one-eye is possible.
