You know that feeling when everyone tells you something is impossible, so you never even try? That is what happened in chemistry for a hundred years. Students memorized a rule, one called Bredt’s rule, and then everyone obeyed it. Professors taught it. Nobody questioned it. And it was wrong. The team of chemists behind this study didn’t set out to …

If you think of helium, you are probably thinking of party balloons and squeaky voices. That doesn’t do the element justice. It has a large number of technical and industrial applications, and is the second most common element in the universe. On Earth, though, it is pretty scarce, and the fact that it is lighter than air and doesn’t react …

In June, Clarivate, the owner of Web of Science, released the 2025 update to the Journal Citation Reports that is described as a ‘comprehensive overview of the world’s leading and trusted academic journals’. Only those journals that have met Clarivate’s quality standards are featured and, for the first time, the release excluded citations to and from retracted content when calculating …

Summary: New research on prairie voles shows that while oxytocin is not strictly necessary for friendship, it plays a vital role in quickly forming and maintaining strong social bonds. Voles lacking oxytocin receptors took up to a week to develop preferences for peers that normal voles formed in a day, and they often failed to prioritize known companions in group …

D. Ross Cameron-Imagn Images The San Francisco 49ers held their 11th training camp practice on Tuesday, as they prepare for Saturday’s preseason opener against the Denver Broncos. Before practice began, the team made some wide receiver moves, re-signing Equanimeous St. Brown to a one-year contract and releasing Andy Isabella, who suffered an ankle injury during Monday’s practice. Here are some …

Lava planets, some no larger than Earth, challenge everything we know about planetary science. These extreme worlds orbit so close to their stars that a single year lasts less than a day. Their surfaces reach temperatures hot enough to melt or even vaporize rock, creating conditions that are completely alien compared to Earth, Mars, or Venus. Yet it is precisely …

Researchers have created the simplest artificial cell ever—just a membrane, an enzyme, and a mission. In a breakthrough that strips life down to its most basic rules, scientists at the Institute for Bioengineering of Catalonia (IBEC) have built a synthetic minimal cell that can move on its own, guided purely by chemistry. Just like bacteria that swim toward food or …

A long-standing mystery about the presence of hydrogen peroxide (H2O2) on Jupiter’s icy ocean moon Europa may be closer to being solved. Hydrogen peroxide forms as a byproduct when energetic particles break apart water molecules, leading to the recombination of OH radicals — highly reactive molecules with unpaired electrons. H2O2 was first observed on Europa by the Galileo Near Infrared …
