AI reveals a shared language guiding cell development‎

As an embryo develops from a small cluster of stem cells, those once "blank slate" cells begin to take on more specialized roles like brain, liver or muscle cells and organize themselves into three-dimensional structures such as tissues and organs.

When schools fail to act, weight-based bullying can continue‎

Young people who experience bullying because of their weight feel that their schools do not take the problem seriously enough. In some cases, they change their own behavior to avoid harassment, according to a new study from Lund University.

Could your plastic film packaging serve a purpose? We won't know until recycling laws change‎

From the clear covering on your microwave meal to the flimsy bread bag lying on the kitchen counter, plastic film is notoriously tricky to recycle. But what if those annoying bits of plastic waste could be put to better use?

The same immune cells play opposing roles in tissue regeneration's balancing act‎

In a study of fingertip regeneration, a team led by JAX senior research scientist James Godwin found that some immune cells in mice can attack and kill cells needed to rebuild bone, while a subset of those same immune cells can protect the bone-making cells and allow regeneration to continue.

New water safety rapid testing method cuts time to results from six hours to 30 minutes‎

FIU researchers have developed a faster, more efficient method to detect forever chemicals in the water system, cutting the testing time from over six hours to just 30 minutes. These findings, which could enhance how water safety is monitored, were published in the Journal of Chromatography A.

Spain sizzles in hottest September on record: Weather agency‎

Mainland Spain sizzled in its warmest September since records began in 1961, with exceptional heat effectively making it another summer month, national weather agency AEMET said on Friday.

Forecasting air drag with deep learning helps predict when uncontrolled satellites and rocket stages fall to Earth‎

On May 10, 2025, a spacecraft built in the Soviet Union to land on Venus came home. Launched in 1972, Cosmos-482 was stranded by a failed upper stage of its rocket and circled Earth for 53 years. In its last days, several space agencies and research groups forecasted when it would fall, and therefore where. Roscosmos later reported that it came down in the Indian Ocean, west of Jakarta.

Fully automated testing of bulk metals paves the way for AI-driven materials development‎

Developing stronger and tougher structural metals such as steel requires exploring an enormous range of processing conditions. Even for the same alloy composition, heat treatment can dramatically change the material's microstructure and mechanical properties. If there were a way to automate the process, we could pinpoint ideal conditions much more efficiently. However, experiments on bulk metallic materials are difficult to automate because they require handling solid specimens and integrating large, specialized equipment.

Even or odd numbers: A single molecule makes all the difference in the quantum world‎

The researchers in the Quantum Detection Microscopy group at CIC nanoGUNE, in collaboration with chemists at CiQUS of the University of Santiago de Compostela, have demonstrated that adding or removing a single molecule from a quantum chain can fundamentally change its interaction with a superconductor.
