NewsResearchers explore ways to better safeguard romaine supply from E coli outbreaks
E. coli outbreaks in romaine lettuce have long been a public health concern. and now a new paper suggests that a combination of efforts in the field, and even postharvest techniques, can minimize risk to human health.

NewsHarmful algae blooms have secret to success over other algaes
An alga that threatens freshwater ecosystems and is toxic to vertebrates has a sneaky way of ensuring its success: It suppresses the growth of algal competitors by releasing chemicals that deprive them of a vital vitamin.

NewsAvian flu has major economic costs for dairy industry
A new paper shows that the highly pathogenic avian influenza H5N1 virus causes severe mastitis and decreased milk production in dairy cows, a drop-off that may extend beyond the clinical outbreak period.

NewsBacteria hitch a ride on yeast puddles to zoom around
Researchers found that bacteria can speed up by using the fluid pockets shaped by neighboring yeast cells. These microscopic moisture trails allow bacteria to swim farther and spread faster—revealing a new way for microbes to travel through soil, plants, and the human body.

NewsCotton virus circulated undetected in US fields for nearly 20 years, study finds
A virus responsible for damaging cotton crops has been lurking in U.S. fields for nearly 20 years – undetected. Cotton leafroll dwarf virus (CLRDV), thought to be a recent arrival, was infecting plants in cotton-growing states as early as 2006.

NewsTopical gel relieved ear infections in animals after just one dose
Researchers report a topical antibiotic gel that, applied once, cured middle ear infection within 24 hours in chinchillas. a single dose of treatment for middle ear infections could improve patient compliance and potentially reduce pediatric antibiotic usage.

NewsNew AI technique can uncover antiviral compounds using limited data
Artificial intelligence algorithms have been combined with traditional laboratory methods to uncover promising drug leads against human enterovirus 71 (EV71), the pathogen behind most cases of hand, foot and mouth disease.

NewsBacterial ‘jumping genes’ can target and control chromosome ends
Researchers have discovered a new mechanism that transposons, or “jumping genes” use to survive and propagate in bacteria with linear DNA, with applications in biotechnology and drug development.

NewsNew COVID-flu vaccine platform could provide broad, lasting protection
Researchers have developed a new vaccine platform that could provide more robust, longer-lasting protection from both COVID-19 and influenza, and broader immunity to different flu strains.

NewsBackyard poultry face HPAI risk when migrating mallards stop to rest
Knowing where, when and for how long mallard ducks – natural carriers of avian influenza – stop and rest as they migrate can help predict the probability that they will spread bird flu to backyard poultry flocks, according to a new study.

NewsProtein shuttling mechanism helps bacteria pump out antibiotics
By a joint-university effort, the mechanism of a bacterial efflux pump complex to remove molecules, including antibiotics, has been determined and the extent of bacterial toxin resistance by the complex has also been evaluated with a cutting-edge device.

NewsThe deadly pathogen that decimated sea urchins in Eilat has now spread to the Indian Ocean
The pathogen responsible for the mass deaths of sea urchins along the Red Sea coast is the same one responsible for mass mortality events among sea urchins off the coast of Réunion Island in the Indian Ocean.

NewsStudy unveals a novel protective mechanism in bacterial cell wall
Researchers from Umeå University, Sweden, and Cornell University, USA, have discovered a widespread mechanism in bacteria that enhances the bacteria’s defense against environmental threats. Source: Umeå University Sara Hernandez and Laura Alvarez, two of the researchers behind the study in the lab. The discovery, which may be ...

NewsExtreme microbe reveals how life’s building blocks adapt to high pressure
An AI tool has helped scientists discover how the proteins of a heat-loving microbe respond to the crushing conditions of the planet’s deepest ocean trenches, offering new insights into how building blocks of life might have evolved under early Earth conditions.
