Stellar collision may explain why Orion Nebula's planet-forming disks appear younger than its stars
The Orion Nebula is a large star-forming region visible to the naked eye. Some of the young stars in the nebula are surrounded by disks of gas and dust in which...
Scientists uncover the molecular pillars that shape our cells' powerpacks
Mitochondria are the tiny powerpacks that supply most of the energy our cells need. Their ability to generate this energy relies on a distinctive architecture:...
Mechanism behind PARP1-mediated DNA repair characterized, offering insight into targeted cancer therapy
When DNA is damaged, cellular processes respond and repair the DNA. Inhibiting DNA damage repair can be therapeutically beneficial in cancers with genetic vulne...
Rare fossils reveal what ancient Denisovans may have looked like
Whenever anything is written about the Denisovans, the word "mysterious" is almost guaranteed to appear. That is because we just don't know a lot about this ext...
Black holes spinning near maximum rate could split in two, calculations suggest
Two black holes can collide and merge into one. But could the opposite happen: could a single black hole split into two smaller ones? That question is explored...
Hoarders without borders: Study suggests investors aid international expansion
Venture capital firms can help young businesses expand internationally by providing funding as well as market knowledge, expertise and access to professional ne...
From sea anemone to human fertility: A new research organism for understanding meiosis
Every egg cell and sperm cell depends on meiosis, a tightly choreographed process in which chromosomes find their partners, exchange genetic material and then d...
An ancient virus in chimpanzee DNA switches off a gene that is active in humans
Humans and chimpanzees share almost all their genes. Despite this, our brains have developed in different ways. Researchers at Lund University in Sweden have no...
As flood risk rises, some communities question the idea of resilience
Climate change is increasing flood risk across the U.K. As floods become more frequent and intense, communities are increasingly encouraged to become resilient...
Paleolithic human DNA reveals east-west connections across Ice Age Europe
More than 30,000 years ago, people associated with one of Europe's major Paleolithic cultures (the Gravettian) were more interconnected than previously thought....
Scientists find key to predicting some El Niño events 12 months ahead
Scientists have identified the conditions that make it possible to predict some El Niño and La Niña events up to a year in advance, potentially giving communiti...
AI is solving math problems that stumped humans. What comes next?
A few short years ago, asking AI to add two four-digit numbers together for a third-grade math assignment would have been a bad idea. Over half the time, the an...
