NewsGut bacteria linked to osteoporosis risk in primary hyperparathyroidism
Researchers studying primary hyperparathyroidism, a common endocrine disorder characterized by excessive secretion of parathyroid hormone, have identified Bifidobacterium longum as a potential microbial driver of bone loss through immune-mediated mechanisms.

NewsScientists track breakthrough single-dose vaccines for Andes hantavirus strain
Researchers report the development of new vaccines that, in animal testing, provided full protection against the deadly Andes hantavirus after a single dose. They are working to fast-track these single-dose vaccines into human clinical trials.

NewsAntibody clues could improve long Covid care and prognosis
Researchers have found that SARS-CoV-2 antibody patterns may help assess infection history, symptom severity, and cognitive complications in long Covid.

NewsCapacity of certain unicellular organisms to stick together may be key to animal evolution
Researchers have found that after feeding a specific bacteria to a certain unicellular relative of animals, the single cells began to stick to one another, revealing a possible mode by which our ancestors began to evolve into animals billions of years ago.

NewsBiochar may help stop antibiotics from escaping through hidden soil highways
A new study reveals that biochar can do more than simply trap pollutants. It may actively redirect antibiotic movement in structured soils, helping reduce the risk of contamination in nearby water systems.

NewsResearchers investigate the underlying causes of post-treatment Lyme disease syndrome
With an estimated one million Americans afflicted with post-treatment Lyme disease syndrome, newly funded research seeks to determine whether the condition is triggered by a persistent autoimmune response, and if a test can be devised to pinpoint who is more likely to develop it.

NewsElsevier launches Ebola Information Center with free clinical and research resources
Elsevier has launched an Ebola Information Center to provide healthcare professionals, researchers, policy makers and the public with free access to critical clinical and research information to support the global response to this outbreak.

NewsStudy deploys DNA to track infectious bacteria from raccoons via rivers to humans
The emerging infectious bacterium Escherichia albertii has caused outbreaks of severe food poisoning and hospitalized people through contaminated water and foods, such as salad ingredients. A new study suggests a pathway by which invasive raccoons transmit infections to humans.

NewsMolecular anchors on gut phages may open new avenues for therapeutic development
A new study has identified phage surface proteins acting as molecular anchors. These proteins confer phages with the ability to attach to human cells. Using genetic engineering, the researchers transferred these adhesion proteins onto the surface of another phage that otherwise lacked this ability.

NewsBiochar’s hidden electron power could unlock cleaner pollution control and energy recovery
A new review highlights how biochar’s natural redox properties may help overcome key barriers to large-scale environmental applications.

NewsSugar-free diets may disrupt gut microbiome
Eliminating sugar from your diet may be more detrimental than previously thought, according to an animal study. Mice fed a sucrose-free diet developed impaired glucose control, insulin resistance, gut microbial imbalance, intestinal inflammation and fatty liver changes, despite having no significant differences in body weight compared with control mice.

NewsThousands of young people to be offered two-dose MenB vaccine ahead of autumn
Thousands of young people across England will get protection against meningococcal B disease (MenB) through a one-off vaccination programme launching ahead of the 2026 academic year.

NewsMicroscope breakthrough will open unprecedented view into cells
In a landmark achievement in biological imaging, researchers have announced the successful demonstration of the laser phase plate, a novel device that dramatically improves the contrast of images produced by cryo-electron microscopes, opening up an entirely new view of human biology.

NewsMaterial extends shelf life and prolongs release of fungus used as bioinsecticide
Encapsulating Beauveria bassiana in a biopolymer made of cellulose and aluminum increased the viability of the fungus from 69% to 85% after five months of storage, providing a more sustainable alternative that releases the bioinsecticide.

NewsAsk the expert: World Cup travel and Ebola risk
Luis Ostrosky, MD, division chief of infectious diseases at McGovern Medical School at UTHealth Houston and chief epidemiology officer for Memorial Hermann Health System addresses the Ebola outbreak in Congo and Uganda and how the United States could be affected through travel.

NewsLouse-borne relapsing fever: How the pathogen evades the immune system
A research team has now identified and characterized five closely related proteins that are crucial for the survival of Borrelia recurrentis in the human body. These so-called Chi proteins appear to have evolved from a common ancestor and are therefore considered homologous.

NewsPathogenic fungus transmitted by domestic cat scratches is present in wild animals
Researchers detected pathogenic species of Sporothrix in the internal organs of mammals, birds, and reptiles that were killed by vehicles on Brazilian roads. The study reveals a new reservoir for fungi and highlights the need for surveillance.

NewsFasting-mimicking diet reduces gum disease inflammation
A new study highlights how lifestyle modifications could be important alongside plaque control in managing gum disease. While fasting has been linked to reduced inflammation around the body, this is the first to establish a relationship with gum disease too.

NewsAs California warms, cases of dengue fever are expected to grow
Historically, dengue fever has been rare in California. But according to new research, a warming climate is making parts of the state more hospitable to the illness — and the mosquitoes that carry it.

NewsGLP-1s may alleviate depression in mice through the microbiome
Some people taking GLP-1 drugs for diabetes and obesity experience mental health benefits. In a mouse model study, researchers report that these improvements appear to result from gut microbiome changes that lead to an abundance of a microbe strain known to have a favorable effect on neurons related to stress.
