Climate change poses a major threat to the organisms such as plankton that form the base of the marine food web. A team of scientists from MARUM – Center for Marine Environmental Sciences at the University of Bremen have used the fossil record to show that only a relatively minor amount of climatic change is needed to affect plankton communities. They have published their findings in Communications Earth & Environment.

Certain nutrients in food can trigger a mild stress response in nematodes. But instead of making them sick, this actually helps them stay healthier as they age, according to researchers at the University of Basel, Switzerland.

Researchers at the Icahn School of Medicine at Mount Sinai in New York, Boston Medical Center, and Boston University Chobanian & Avedisian School of Medicine, have developed a software platform to help scientists more easily analyze the molecular structure of tissue in both healthy and disease states. Details on the platform, called Giotto Suite, were reported in the October 1 online issue of Nature Methods [DOI: 10.1038/s41592-025-02817-w].

New research published in Nature Ecology & Evolution sheds light on the timelines and pathways of evolution of fungi, finding evidence of their influence on ancient terrestrial ecosystems. The study, led by researchers from the Okinawa Institute of Science and Technology (OIST) and collaborators, indicates the diversification of fungi hundreds of millions of years before the emergence of land plants.

Recent studies led by an international consortium of researchers, including scientists from the San Diego Zoo Wildlife Alliance and the Museo de Historia Natural de la Universidad Nacional Mayor de San Marcos, unveiled groundbreaking findings in biodiversity conservation through in situ DNA barcoding in the Peruvian Amazon. 

Long COVID is a chronic condition that causes cognitive problems known as “brain fog,” but its biological mechanisms remain largely unclear. Now, researchers from Japan used a novel imaging technique to visualize AMPA receptors—key molecules for memory and learning—in the living brain. They discovered that higher AMPA receptor density in patients with Long COVID was closely tied to the severity of their symptoms, highlighting these molecules as potential diagnostic biomarkers and therapeutic targets.
