On an October morning in 2023, a chemical explosion detonated in a tunnel under the Nevada desert was the launch of the next set of experiments by the National Nuclear Security Administration, with the goal to improve detection of low-yield nuclear explosions around the world.

A new study sheds light on the complexities of achieving optimal vitamin D status across diverse populations. Despite substantial research on the determinants of vitamin D, levels of vitamin D deficiency remain high. Researchers believe their findings have significant implications for the development of tailored recommendations for vitamin D supplementation.

Scientists have developed lubricant additives that protect both water turbine equipment and the surrounding environment.

Some of the ocean’s tiniest organisms get swept into underwater currents that act as a conduit that shuttles them from the sunny surface to deeper, darker depths where they play a huge role in affecting the ocean’s chemistry and ecosystem, according to new research.

The global demand for palm oil — the most widely consumed vegetable oil on the planet, in everything from instant noodles to lipstick — is driving worldwide tropical deforestation. While many studies have shown the loss of biodiversity when rainforests are converted to oil palm plantations, researchers have now shown the far-reaching and wide-ranging disturbances to the watersheds in which such plantations occur.

Working with human breast and lung cells, scientists say they have charted a molecular pathway that can lure cells down a hazardous path of duplicating their genome too many times, a hallmark of cancer cells.

Physicists developed a technique to arrange atoms in much closer proximity than previously possible, down to 50 nanometers. The group plans to use the method to manipulate atoms into configurations that could generate the first purely magnetic quantum gate — a key building block for a new type of quantum computer.
