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.

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

NewsCAROSEL offers new ‘spin’ on monitoring water quality in real time - and tracking harmful algal blooms
Researchers can continuously track the exchanges of different forms of nitrogen between bottom sediments and the overlying water. Their novel approach enables measuring how much ammonium (NH₄⁺) is released from sediments in real time, multiple times a day, over an extended period.

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.

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.

NewsPlasma strategy boosts antibacterial efficacy of silica-based materials
Scientists have developed a novel two-step plasma strategy to modify mesoporous silica-supported silver nanoparticles, enabling them to achieve strong antibacterial activity and accelerated wound healing.

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.

NewsUK’s failure to retain and scale science and technology causing economy to bleed out, warns Lords Committee
The UK’s failure to retain and scale its science and technology companies has now reached crisis point and is causing the UK economy to bleed out, warns a damning report.

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.

NewsDemographic shifts could boost drug-resistant infections across Europe
The rates of bloodstream infections caused by drug-resistant bacteria will increase substantially across Europe in the next five years, driven largely by aging populations, according to a new paper.

NewsNew approach expands possibilities for studying viruses in the environment
A new method vastly improves on the existing approach for single-cell genetic sequencing, enabling scientists to read the genomes of individual cells and viral particles in the environment more quickly, efficiently, and cost-effectively.
