Mar. 24, 2025 For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how chromosomes change shape during cell division. Certain protein complexes help fold DNA into overlapping loops that repel each other, which then stack to create a rod-like structure. This is the first ...

Mar. 18, 2025 In the microscopic world of bacteria, gene transfer is a powerful mechanism that can alter cellular function, drive antibiotic resistance and even shape entire ecosystems. Now an interdisciplinary group of researchers has developed an innovative RNA 'barcoding' method to track these genetic exchanges in microbial communities, providing new insights into how genes move across ...

Mar. 24, 2025 A storm, even once it has passed, can leave traces in the ocean that last for thousands of years. These consist of sediment layers composed of coarse particles, which are different from the finer sediments associated with good weather. In the Caribbean, an international research team has now examined such sediments using a 30 m long core from a ...

Mar. 18, 2025 Brook trout may have a genetic trick up their scales when it comes to adapting, with limitations, to heatwaves that threaten their existence. Scientists have known for years that brook trout -- an iconic coldwater fish species native to streams and lakes in the eastern United States and Canada -- are extremely vulnerable to warming temperatures, ...

Mar. 18, 2025 Livestock agriculture is bearing the cost of extreme weather events. A new study explores how heat stress affects U.S. dairy production, finding that high heat and humidity lead to a 1% decline in annual milk yield. Small farms are hit harder than large farms, which may be able to mitigate some of the effects through management ...

Mar. 18, 2025 Although fungi of the genus Piloderma are common, scientists have now discovered five previously unknown species. One of these is one of the most widely distributed species in Northern Europe, while another is found only in old-growth forests. The discoveries show that diversity in this genus is much greater than previously thought and that some of its species are at risk of disappearing as ...

Mar. 17, 2025 Researchers have identified the economic and political borders separating El Argar, considered to be the first state-society in the Iberian Peninsula, from its La Mancha and Valencia Bronze Age neighbors some 4,000 years ago. These communities, with less centralized social structures, maintained complex relations with the Argaric culture. The study, based on an innovative analysis of pottery ...
