Bacteria modify their ribosomes when exposed to widely used antibiotics, according to new research. The modified ribosomes have changes specifically in the regions where antibiotics latch on to and halt protein production. The study found this made the bacteria more resistant to the drugs. The subtle changes might be enough to alter the binding site of drug targets and constitute a possible new mechanism of antibiotic resistance. Read more ›

More than a million years ago, on a hot savannah teeming with wildlife near the shore of what would someday become Lake Turkana in Kenya, two completely different species of hominins may have passed each other as they scavenged for food. Scientists know this because they have examined 1.5-million-year-old fossils they unearthed and have concluded they represent the first example of two sets of hominin footprints made about the same...

A tiny, four-fingered 'hand' folded from a single piece of DNA can pick up the virus that causes COVID-19 for highly sensitive rapid detection and can even block viral particles from entering cells to infect them, researchers report. Dubbed the NanoGripper, the nanorobotic hand also could be programmed to interact with other viruses or to recognize cell surface markers for targeted drug delivery, such as for cancer treatment.

Researchers have quantified for the first time the global emissions of a sulfur gas produced by marine life, revealing it cools the climate more than previously thought, especially over the Southern Ocean. The study shows that the oceans not only capture and redistribute the sun's heat, but produce gases that make particles with immediate climatic effects, for example through the brightening of clouds that reflect this heat.

New research has revealed that the Ninetyeast Ridge -- the Earth's longest straight underwater mountain chain -- formed through a different process than previously believed. Stretching 5000 km along the Indian Ocean's 90-degree east longitude and nearly matching the length of North America's Rocky Mountains, the ridge offers crucial new insights into the movement of the Earth's tectonic plates.

A new study represents a significant step forward in scientists' understanding of Alzheimer's disease. A team of investigators has examined the role of two proteins found in the brain and suggest the stability of their relationship to one another is crucial for memory formation and maintenance. Disruptions in this mechanical signalling pathway could lead to the disease. This is the first time this connection has been identified and could pave... Read more ›

Large language models, a type of AI that analyses text, can predict the results of proposed neuroscience studies more accurately than human experts, finds a new study. The findings demonstrate that large language models (LLMs) trained on vast datasets of text can distil patterns from scientific literature, enabling them to forecast scientific outcomes with superhuman accuracy. The researchers say this highlights their potential as powerful tools for accelerating research, going... Read more ›

New research, based on data from more than 28,000 caregivers in three countries, shows that the longer individuals spend caring for loved ones, the more their well-being suffers, regardless of the caregiving context. These findings underscore the need for policy discussions to alleviate the burden of informal care. Read more ›
