NewsInvisible smart bug fights gum disease
Current treatments for periodontitis often fail because they cannot simultaneously eliminate stubborn bacterial biofilms and calm the runaway inflammation that follows. Now researchers have engineered a living bacterium that does both, in the right order.

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.

NewsHappy 100th birthday! Eight inspiring quotes from Sir David Attenborough
Happy centenary! As Sir David Attenborough celebrates his 100th birthday today, we dig up some of his most famous quotes that celebrate the vital role that microbes and their ecosystems play on planet Earth.

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.

NewsBoyce Thompson Institute names Dr. Natalie Hoffmann inaugural Jane Silverthorne Postdoctoral Fellow
How do beneficial fungi grow into and through plant cells without destroying them in the process? That question sits at the center of Dr. Natalie Hoffmann’s research – and it’s what earned her the inaugural Jane Silverthorne Postdoctoral Fellowship at the Boyce Thompson Institute (BTI).

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.

NewsThe Nexus of Food Systems, Ecosystems and Human Health: Sign up for our fascinating free webinar!
What if health is not produced by humans alone, but co-created with the ecosystems, organisms, and food systems we depend on? A fascinating free webinar will explore how microbes connect people to food systems and the ecosystems that undergird food production.

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.
