Metal hydride molecule trapped with laser light opens path to ultracold hydrogen

Controlling and trapping molecules, units of a substance consisting of two or more chemically bound atoms, with laser light is significantly more challenging than trapping individual atoms. This is because molecules exhibit more complex vibrational and rotational dynamics that ma

Most bees are solitary and don't live in hives: How climate change risks them starving

When we think of bees, we often think of flowers. The more flowers, the better, right? Well, not exactly. Like us, bees need to consume specific nutrients in suitable amounts and combinations.

Researchers discover why fructose doesn't satisfy hunger like glucose

A new study found that fructose and glucose may look the same on a nutrition label, but the brain treats them very differently. In mice, glucose strongly reduced activity in hunger-promoting brain cells, while fructose had a much weaker effect. High-fructose corn syrup triggered

A single origin story for the Milky Way's most mysterious stars

Lurking at the heart of the Milky Way, Sagittarius A* (Sgr A*) is a supermassive black hole four million times the mass of the sun, surrounded by a puzzling collection of young, massive stars whose orbits have long defied explanation. Astronomers have proposed various competing t

How everyone pays the cost for patents on seeds, and private companies get rich from keepi

The United States is one of only a handful of countries that allows companies to hold patents on plant varieties. As a result, a small number of corporations can—and do—suppress competition in the seed industry, stifle innovation, and turn taxpayer subsidies intended for farmers

Giraffes combine quantities similarly to addition

In addition to humans, some species of primates and birds have demonstrated under experimental conditions their ability to manipulate quantities in tasks that require combining or separating them, in a manner similar to addition or subtraction. Now, a study by the University of B

Heat is destroying Australia's underwater forests. Seaweed biobanks could help save them

Australia's Great Southern Reef is built not by coral but by seaweed. The seaweed forests on these rocky reefs stretch more than 8,000 kilometers (5,000 miles) around southern Australia.

Cultural values may decide when comforting others feels like real support

When someone you love is upset, your first instinct may be to comfort them. To reassure them. To make them feel better. But what if that instinct isn't universal?

Testing the orbital mechanics of giant mirrors

Giant mirrors in space have been a staple of science fiction for decades. But so far, there's been very little work looking at the actual physics behind the concept—possibly because we're still so far from making them ourselves. Still, they could potentially serve as a passive te

How PFAS chain length influences environmental fate and water treatment

Per- and polyfluoroalkyl substances (PFAS), often referred to as "forever chemicals," are among the most persistent contaminants found in water systems worldwide. Their strong carbon-fluorine bonds make them highly resistant to degradation, allowing them to remain in the environm
