Some biologists speculate that animals will get smaller with global warming to reduce heat stress. While this may be true of warm-blooded animals, what about exotherms like insects? Thanks to a 65-year-old grasshopper collection, scientists have documented that some species -- those overwintering as juveniles -- got larger over the years, helped by an earlier green spring. Grasshoppers with other lifestyles got smaller. Much of this can be predicted given... Read more ›

Prolonged illnesses like cancer and chronic infections often leave the immune system in a state of exhaustion, where its frontline defenders -- T cells -- lose their ability to function effectively. Researchers have identified a rare type of immune cells, called stem-like T cells, that holds the key to maintaining powerful, long-term immune responses. Read more ›

A new study of satellite imagery and high-resolution climate model data upends previous assumptions and provides insight about how the atmosphere and ocean weather patterns interact. The new research reveals the surprising ways atmospheric winds influence ocean eddies, shaping the ocean's weather patterns in more complex ways than previously believed. Read more ›

A carnation-like nanostructure could someday be used in bandages to promote wound healing. Researchers report that laboratory tests of their nanoflower-coated dressings demonstrate antibiotic, anti-inflammatory and biocompatible properties. They say these results show these tannic acid and copper(II) phosphate sprouted nanoflower bandages are promising candidates for treating infections and inflammatory conditions. Read more ›

DNA evidence has confirmed killer whales in Australia hunted a white shark for its liver. Based on DNA analysis from the bite wounds on the carcass of a large white shark washed ashore near Portland in Victoria in 2023, the study identified that killer whales were responsible for consuming the mid-section containing the nutritionally rich liver.

Researchers have made new discoveries about amniotic fluid, a substance historically not well understood in medical research due to the difficulty in obtaining it during pregnancy, especially across gestation. The multidisciplinary research team is eager to harness the potential of this vital substance to improve prenatal and maternal health. Read more ›

In a comprehensive systematic review and meta-analysis, researchers have taken a deep dive into the effects of cold-water immersion on health and wellbeing. Analyzing data from 11 studies with 3177 participants, researchers found that cold-water immersion may lower stress, improve sleep quality, and boost quality of life. Read more ›

Biomedical engineers have developed an AI-based platform that designs short proteins, termed peptides, capable of binding and destroying previously undruggable disease-causing proteins. Inspired by OpenAI's image generation model, their new algorithm can rapidly prioritize peptides for experimental testing. Read more ›

As grasslands get abandoned, controlled burning is discussed as a labor-saving method of keeping forests at bay. A research team found that this method results in higher biodiversity and a higher prevalence of endangered plant species in some grasslands compared to others, depending on what soils they grow on.

It's well known that consuming sugary drinks increases the risk of diabetes, but the mechanism behind this relationship is unclear. Now researchers show that metabolites produced by gut microbes might play a role. In a long-term cohort of US Hispanic/Latino adults, the researchers identified differences in the gut microbiota and blood metabolites of individuals with a high intake of sugar-sweetened beverages. The altered metabolite profile seen in sugary beverage drinkers... Read more ›

Researchers have developed a new microscopy technique to observe how ribosomes function in cells. With this method, they can monitor individual ribosomes as they convert mRNA into proteins. The researchers discovered that ribosomes help each other when encountering difficulties, a process they refer to as 'ribosome cooperativity'. This technique and the findings, published in Cell, provide insights into how proteins are made and offer other researchers a tool to better... Read more ›
