Probing the power of the winds
Young researchers have been exploring the energy in wind to see how best they might tame it, harness it and understand its role in shaping the natural world.

Explainer: Winds and where they come from
Temperature and pressure are critical factors affecting why the wind blows where it does. Understanding the nature of wind can teach us a lot about weather.

Scientists Say: Neutron star
When large, ancient stars die, they explode. But they don’t disappear. The remnants become incredibly dense neutron stars.

Scientists at last link some extreme weather to human activities
Scientists say that research shows several of 2016’s extreme weather events would never have happened without the help of human-caused climate change.

Major gravity experiment recreated aboard a satellite
A spacecraft was used to “drop” two objects and test their rate of fall. The new, super-precise findings confirm objects will fall at the same rate (in the absence of air resistance) — and that when it comes defining the effects of gravity, Einstein got it right.

Escaping narwhals can freeze and flee at the same time
Narwhals’ heart rates plummet while diving quickly to get away from people. The combination may stress the whales as human activity increases in the Arctic.

Scientists Say: Epidermis
The epidermis is the outer layer of your skin. It helps protect you from dangerous things in the environment, and helps control how much water evaporates from your body.

Water waves can have literally seismic impacts
Certain types of seismic waves are generated by waves on large lakes. These ground waves could be used to map fault zones or to monitor ice cover in polar lakes.
