NewsPregnant women’s mental images are directly linked to vaccine hesitancy and uptake
When pregnant women think about vaccinations, many experience vivid mental images – such as a sick baby in hospital – that have a direct link to their opinion of the vaccine and whether they ultimately have it, new research has shown.

NewsThawing Arctic soil awakens only half of soil microbes, new study reveals
A study shows that even after months of thawing, around half of the microorganisms in High Arctic soils remain dormant. This challenges the assumption that warming uniformly boosts microbial activity and carbon release from thawing permafrost.

NewsGut microbiota plays a role in metabolic health after bariatric surgery
Changes in gut microbiota after bariatric surgery are strongly linked to altered metabolic health and sustained improvement in type 2 diabetes. A study shows changes in gut bacterial composition and function are associated with metabolic improvements, including insulin release and blood sugar control.

NewsIron minerals help decide whether dissolved organic matter becomes microbial food or long-term carbon
A new study shows how iron oxide minerals can reshape dissolved organic matter before microbes begin to break it down. The research focuses on goethite, and reveals that mineral adsorption does not simply remove organic matter from water.

NewsExpanded tuberculosis screening does not speed up treatment initiation or improve survival in hospitalized patients with HIV
According to the EXULTANT trial, adding molecular tests on sputum, urine and stool samples does not appear to outperform the standard WHO-recommended diagnostic approach.

NewsHow soil bacteria help plants defend themselves against disease
A study reveals the mechanism by which surfactin, a molecule produced by beneficial soil bacteria, activates plants’ immune defences. This mechanism, distinct from the classical paradigm of immune recognition, relies on direct interaction with the plant cell membrane.

NewsAnti-CRISPR stops the protein assembly line in bacteria
Bacteria fend off invading viruses with molecular scissors that slice up viral DNA, but viruses can fight back with a molecular trick that stops the scissors from ever being made. A viral “anti-CRISPR” protein sits on the ribosome and jams it as a CRISPR protein named Cas12 begins to form.

NewsMouse study suggests high-fat diets during pregnancy worsen severe GI illness in preterm babies
A new mouse study suggests a link between a high-fat prenatal diet and induction of potentially deadly symptoms of necrotizing enterocolitis (NEC) in premature babies.

NewsScientists take crucial step in developing world’s first measles treatment
Scientists have characterized human antibodies capable of neutralizing measles virus. These antibodies bind to key sites on measles virus and prevent the virus from entering host cells.

NewsHow bacteria ‘chat’ their way to carbon-neutral water treatment
Global climate goals demand that wastewater treatment plants transform their operations. A new review reveals that quorum sensing (QS), the chemical communication system bacteria use to coordinate behavior, could be the key.

NewsGlobal outbreaks may fuel violence against women — but most cases go unmeasured
Violence against women and girls may increase during infectious disease outbreaks — as economic strain, isolation and disrupted services reshape daily life — yet those impacts remain largely unmeasured, according to a new study.

NewsScientists discover how gut bacteria toxin invades colon cells to trigger cancer
A common gut bacterium, Bacteroides fragilis, drives colon tumor formation, potentially leading to colorectal cancer, by secreting a toxin that damages the lining of the colon. Researchers have now shown that the B. fragilis toxin BFT must first bind host receptor claudin-4 before it can cause damage.

News‘Atomic snapshots’ of proofreading enzyme could lead to better COVID-19 drugs
A research team used images generated by a cryogenic electron microscope (cryo-EM) to observe the interplay between SARS-CoV-2 proofreading enzyme exoribonuclease (ExoN) and RNA incorporated with antivirals such as remdesivir, sofosbuvir and bemnifosbuvir.

NewsNeedle-free flu vaccine aims to boost children’s immunity
A new study will explore the effects of a nasal spray flu vaccine on children’s immune systems, aiming to boost future protection and lower vaccine hesitancy rates.

NewsSeasonal COVID-19 vaccination in 2025/26 reduced risk of illness by half in Canada
An interim analysis estimates that the COVID-19 vaccine for the 2025/26 season reduced the risk of illness in Canada by about half at about 9 weeks after vaccination, offering protection beyond the vaccine’s target strain.

NewsTuberculosis risk: promising approaches for screening and prediction
It is currently difficult to detect TB in its early stages, or predict who will go on to have TB, and therefore preventive treatment is not widely used. Researchers assessed whether a blood-based 3-gene host-response test can detect active tuberculosis and help predict future disease.

NewsLong-term dynamic virological response patterns and clinical outcomes in hepatitis B virus-related cirrhosis
The long-term clinical outcomes of patients with hepatitis B virus (HBV)-related cirrhosis receiving nucleos(t)ide analog (NA) therapy according to virological response patterns remain inadequately defined. A new study aimed to investigate the association between virological response patterns and clinical outcomes.

NewsResearchers find diagnostic delays are common for US pediatric patients with malaria
Researchers found that more than one in four pediatric patients treated for malaria in the United States had a delay in their initial diagnosis, increasing the risk of more severe infection.

NewsLight without electricity? Glowing algae could make it possible
Researchers successfully turned on the “light switch” in algae and kept them lit up using simple chemical solutions. The finding opens the door for future technologies such as autonomous robots that can operate in dark environments and living sensors for water quality.

NewsHead impacts associated with altered gut microbiome in football players
Non-concussive head impacts—hits to the head that don’t cause clinically detectable symptoms—are correlated with subsequent changes to the gut microbiome in a small sample of US collegiate football players, according to a new study.
