Every time a cell divides, it must accurately copy its entire genetic instruction manual. Before this process can begin, cells load their DNA-copying motor—a complex of six subunits known as the MCM2-7 helicase—onto DNA. ...
An African bat whose presence in Sicily had remained an unresolved zoological mystery for almost two centuries has now been documented on Pantelleria Island. A study published in Global Ecology and Conservation reports the ...
Scientists can engineer living cells to perform useful tasks, from producing medicines and sustainable chemicals to detecting disease. Unlike traditional engineered systems, living cells are constantly changing as they grow, ...
Yesterday, I woke to a cold, damp Canberra morning—and silence. The trees around my home were empty of feathered silhouettes. Even the usual bright-eyed, warble-voiced magpies were absent.
The recent announcement of novel, viable viruses created by artificial intelligence (AI) was celebrated as a major advance in the fight against antibiotic resistance. But it also raised urgent concerns about regulation.
Between 29,000 and 19,000 years ago, the planet experienced some of its coldest temperatures and drastic landscape changes at the peak of the Ice Age, during the Last Glacial Maximum (LGM), the period of most extensive global ...
The narwhal's impressive tusk has long been the subject of myths. In the Middle Ages, they were sold as unicorn horns believed to possess magical powers. Now, an international team of researchers led by Aarhus University ...
Scientists at VIB and Ghent University have produced the first high-resolution, cell-by-cell map of how tomato roots respond to colonization by arbuscular mycorrhizal fungi. These ancient fungal partners help plants absorb ...
Researchers at Karolinska Institutet and Stockholm University have developed a new tool that estimates a cell's biological age by analyzing its gene activity. In an article published in the journal Advanced Science, they ...
What if the secret to drought-resistant crops isn't how much water plants use, but when they use it? A new study identifies a daily window that could help breeders develop tomatoes that better withstand drought without sacrificing ...
