Controlled nuclear fusion has several advantages over other power sources for generating electricity. For one, the fusion ...

From the discovery of gravity to the first mission to defend Earth from an asteroid, here are the most important physics ...

Radiation can also be non-ionizing (in the form of visible light or heat), but for this explainer we are focused on the following types of ionizing radiation, which are often placed in the environment ...

Betavolt's nuclear battery lasts 50 years; RF energy harvesting technology promises self-charging batteries for IoT devices.

Physicists have discovered a new form of γ-ray radiation that emerges from tropical thunderstorms — and shown that such invisible bursts of energy are more common on Earth than previously thought.

If we’re going to live on Mars we’ll need a way to grow food in its arid dirt. Researchers think they know a way.

Mobile radiation poses real health risks that should not be ignored, including the danger of burns from malfunctioning ...

With the initial images from each of the instruments aboard ESA's EarthCARE satellite now in hand, it's time to reveal how ...

An experimental program seeks to protect California almond trees from a pesky moth by using X-rays to sterilize the insects.

Radiation therapy treats cancer by using high-energy waves to kill tumor cells. The goal is to destroy or damage the cancer without hurting too many healthy cells. It is given over a certain time ...

But you can still use a nuclear weapon's radiation to vaporize part of the asteroid's surface, creating a very temporary, very hot atmosphere on one side of the asteroid. This should create enough ...
