NewsScientists unlock how viruses punch above their weight
A news study reveals how rabies virus manipulates so many cellular processes despite being armed with only a few proteins. Researchers believe other dangerous viruses like Nipah and Ebola may also work the same way.

NewsUpwelling promotes N-fixing symbiont of Sargassum algae - giving it an edge
An international research team has uncovered the main mechanism behind the algae blooms of the Great Atlantic Sargassum Belt. Identification of the climatic conditions that facilitate this phenomenon allows them to predict future stranding events of Sargassum.

NewsScientists uncover tuberculosis bacterium’s ’heartbeat’, opening door to new treatments
Scientists have identified a molecular system inside Mycobacterium tuberculosis that functions like the organism’s heart or lungs, keeping it alive. The system, known as PrrAB, helps the bacterium generate energy and breathe. When researchers used a gene-silencing tool, the bacterium died.

NewsTwo amino acids help plants decide whether to welcome or repel nitrogen-fixing bacteria
Researchers are one step closer to understanding how some plants survive without nitrogen - a breakthrough that could eventually reduce the need for artificial fertilizer in crops such as wheat, maize, or rice.

NewsAncient viral DNA shapes modern human placentas
Researchers have uncovered how ancient viral DNA controls a gene linked to placenta development and pre-eclampsia, a life-threatening pregnancy disorder. The research could help identify pre-eclampsia risk much earlier.

NewsNot just a common cold: studies show RSV’s severity and impact on long-term health
Often confused for a common cold, respiratory syncytial virus (RSV) can in fact be serious and should be studied more closely. Researchers found that the illness could be of comparable severity to other more well-known respiratory viral infections (RVIs) – such as influenza and COVID-19.

NewsEarly-stage clinical trial demonstrates promise of intranasal influenza vaccine in generating broad immunity
Researchers report encouraging results from an early phase clinical trial that found an experimental intranasal vaccine triggered a broad immune response against multiple strains of H5N1 ’bird flu’, highlighting the potential of mucosal immunization strategies.

NewsAI can speed antibody design to thwart novel viruses: study
Artificial intelligence (AI) and “protein language” models can speed the design of monoclonal antibodies that prevent or reduce the severity of potentially life-threatening viral infections, according to a multi-institutional study
-
NewsNew study finds targets for a new tuberculosis vaccine
A large-scale screen of tuberculosis proteins has revealed several possible antigens that could be developed as a new vaccine for TB, the world’s deadliest infectious disease.
-
NewsStudy unravels Black Sea nitrous oxide conundrum
A new study unravels the ’Black Sea nitrous oxide conundrum’, investigating why large amounts of nitrous oxide are mainly produced in ocean areas that lack oxygen, yet the Black Sea - the world’s largest anoxic basin - appears to emit only little N2O.

NewsFoxtail barley serves as a host for fungal pathogens attacking barley
Researchers report that foxtail barley (Hordeum jubatum), a wild relative of the cultivated crop, can harbor several fungal pathogens and may play a role in the disease epidemiology of barley, potentially serving as reservoirs of inoculum to initiate some diseases.
-
NewsResearchers capture first high-res images of deadly yellow fever virus
Researchers have captured the first high-resolution images of the yellow fever virus (YFV), a potentially deadly viral disease transmitted by mosquitoes that affects the liver.
-
NewsEngineered membraneless organelles boost bioproduction in Corynebacterium glutamicum
Scientists have successfully engineered liquid-liquid phase separation (LLPS)-driven membraneless organelles (MLOs) within the food-grade industrial strain Corynebacterium glutamicum.

NewsAccessible imaging technique can predict cardiac risks in patients with Chagas disease
A simple imaging exam capable of assessing myocardial deformation during contraction has emerged as a promising tool for predicting the risk of cardiac complications in patients with chronic Chagas disease.
-
NewsNew insights on gut microbes that prevent formation of cancer-causing compounds
Gut microbes metabolize dietary nitrates and nitrites and prevent the formation of cancer-causing compounds called nitrosamines. New research sheds light on these processes and pinpoints which types of bacteria are most important.
-
NewsResearch finds higher rare risk of heart complications in children after COVID-19 infection than after vaccination
A whole-population study showed that although these conditions were rare, children and young people were more likely to experience heart, vascular or inflammatory problems after a COVID-19 infection than after having the vaccine — and the risks after infection lasted much longer.
-
NewsTiles, leaves and cotton strips offer practical, affordable method for measuring river health
With the aim of standardising methods for assessing river health and providing a simple, accessible guide for environmental management bodies, researchers analysed the performance of different materials that enable the decomposition processes and organic matter production to be measured.

News‘Rotten egg’ gas could be the answer to treating nail infections, say scientists
Hydrogen sulphide, the volcanic gas that smells of rotten eggs, could be used in a new treatment for tricky nail infections that acts faster but with fewer side effects, according to scientists.
-
NewsHIV significantly affects sleep, with many living in a state akin to chronic jet lag
A new study describes how people living with HIV experience higher rates of sleep issues even when virally suppressed, which has been associated with a higher risk for heart disease, depression and cognitive decline.

NewsNovel technique reveals insights into soil microbe alarm clock
A new study yields clues about when dormant microscopic bacteria and fungi in soil ‘wake up’ and colonize roots, which influences plant growth and health.
