Exposure to certain pollutants, like fine particles (PM2.5) and nitrogen oxides (NOx), during pregnancy and childhood is associated with differences in the microstructure of the brain´s white matter, and some of these effects persist throughout adolescence. These are the main conclusions of a study led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by “la Caixa” Foundation. The findings, published in Environmental Research, highlight the importance of addressing air pollution as a public health issue, particularly for pregnant women and children.

An increasing amount of evidence suggests that air pollution affects neurodevelopment in children...

Women worldwide could see better treatment with new AI technology, which enables better detection of damaged cells and more precisely predicts the risk of getting breast cancer, shows new research from the University of Copenhagen.

Breast cancer is one of the most common types of cancer. In 2022, the disease caused 670,000 deaths worldwide. Now, a new study from the University of Copenhagen shows that AI can help women with improved treatment by scanning for irregular-looking cells to give better risk assessment.

The study, published in The Lancet Dig...

The biggest real-life test of our planetary defenses was carried out in 2022, when NASA’s fridge-sized DART spacecraft smashed into a 160-metre (525-feet) wide asteroid, successfully knocking it well off course.

But for bigger asteroids, merely crashing spaceships into them will probably not do the trick.

When the roughly 10-kilometer wide Chicxulub asteroid struck the Yucatan peninsula around 66 million years ago, it is believed to have plunged Earth into darkness, sent kilometers-high tsunamis rippling around the globe and killed three quarters of all life—including wiping out the dinosaurs.

We humans are hoping to avoid a similar fate.

It’s almost time to dust off the Halloween decorations and adorn the house with all manner of spooky things, including the classic polyester spider webs. Scientists reporting in ACS Nano have made their own version of fake spider silk, but this one consists of proteins and heals wounds instead of haunting hallways. The artificial silk is strong enough to be woven into bandages that helped treat hoint injuries and skin lesions in mice.

Spider silk is one of the strongest materials on Earth, technically stronger than steel for a material of its size.

However, it’s tough to obtai...
