Scientists Say: Haboob
Thunderstorms in the desert create downdrafts that lift desert sand into a moving, wall-like cloud.

Radioactive animals don’t glow — but do show the power of radiation
Wild species exposed to nuclear contamination help show how radiation affects living things — including its risks to people.

Nuclear weapons tests many decades ago have left a radioactive legacy
Decades of aboveground nuclear weapons tests, starting in the 1950s, lightly littered the planet with toxic fallout, which appears to have sickened some people.

Some Antarctic fish arrange their nests into odd shapes
Scientists found nests organized into curves, clusters and ovals on the Antarctic seabed. Such groupings may protect the fish eggs from predators.

Polar bears leave thousands of tons of food scraps for other species
The new finding quantifies how much of polar bears' food goes uneaten. As these bears decline, Arctic scavengers risk losing a critical food source.

Global coral die-offs signal Earth’s first climate tipping point
The corals offer a dire warning, scientists say, and suggests that more such catastrophic points of no return could occur soon — some within a decade.

Let’s learn about lab-grown meat
Lab-grown meat may still be several years away from your local grocery. But such alternatives to farmed or free-range meats are on their way.

Scientists Say: Van Allen belts
Astronomers have detected these radiation belts around Earth and beyond. Jupiter’s belt is thousands of times as intense as Earth’s.
