NewsResearchers combine bacteria and viruses to demonstrate a new way to fight cancer
Researchers have designed non-toxic Salmonella bacteria to deliver viruses that are safe to humans but potent against liver and pancreatic cancer tumors. Animal models treated with this combination of bacteria and viruses saw almost all their tumors eliminated and lived significantly longer.

NewsThe road to better health requires a map of the microbes in your mouth
Different parts of your mouth have entirely different bacterial communities, reveals a new microbial map. Researchers believe mapping these microbial niches will provide a census of the good bacteria present in the mouth and help to develop targeted therapies, such as probiotics, to maintain oral health and prevent disease.

NewsResearcher investigates how a bioengineered peptide can break through harmful bacterial ‘fortresses’ and curb severe infections
A researcher is refining a powerful therapy for drug-resistant bacteria that pierces the gooey coating that anchors and protects such germs from the drugs we take to kill them. She has found that an antimicrobial peptide naturally found in cows weakens the biofilm defenses of Klebsiella pneumoniae bacteria and destroys it.

NewsScientists map the microbes behind a climate-regulating gas in India’s busiest estuary — a first
When bacteria in the water and sediment break dimethylsulfoniopropionate down, they release dimethylsulfide (DMS), a gas that drifts into the atmosphere and helps form clouds by seeding cloud condensation nuclei. A new paper reports the first-ever study of DMSP concentrations and the bacteria that degrade it along the entire length of the Cochin Estuary.

NewsResearchers discover a new antibiotic — and a new way to kill drug-resistant bacteria
Researchers have discovered a new antibiotic that kills some of the world’s most dangerous and drug-resistant bacteria by targeting a previously unknown vulnerability. Manikomycin has shown early effectiveness against priority pathogens including Salmonella, E. coli, and Klebsiella.

NewsResearcher studying probiotics to fight acid reflux and esophageal cancer
Patients with acid reflux, which occurs when stomach acid pushes up into the esophagus, know the symptoms all too well: heartburn, belching, chest pain and trouble swallowing. Acid reflux also increases the risk of esophageal cancer, but researchers are investigating how a simple probiotic could treat and prevent both conditions.

NewsAntibiotics for common sore throats have very limited effect on Strep spread
Antibiotics for sore throats have hardly any preventive effect against serious streptococcal infections in the population, according to a study. Instead, healthcare needs to quickly recognize warning signs of a serious infection.

NewsResearchers discover how to turn one germ’s drug resistance into an Achilles’ heel
As Mycobacterium tuberculosis mutates to protect itself from rifampicin, it also creates new weak points that other therapies could exploit. A new study shows that the most common rifampicin-resistance mutation slows bacterial RNA polymerase, creating vulnerabilities that future combination therapies may be able to target.

NewsMagnetic biochar gel helps keep arsenic and antimony out of rice
A new study reports a promising strategy for mining-impacted regions: a magnetic silicon-enriched biochar gel that can immobilize both arsenic and antimony in contaminated paddy soil and reduce their accumulation in rice grains.

NewsEU project aims to make climate-neutral plastics and cosmetics using bacteria
A European research team is aiming to revolutionize the chemical industry: as part of the CarboNcare project, scientists are developing bacteria that can produce important chemical base materials from sustainable methanol – thereby replacing fossil resources.

NewsEngineered gut bacteria therapy emerges as scalable potential alternative to fecal microbiota transplants following clinical trial
Researchers have developed a new manufacturing platform for producing targeted mixtures of beneficial gut bacteria, an approach that could help expand access to microbiome-based therapies for patients with recurrent Clostridioides difficile (C. difficile) infection.

NewsRedesigning an elusive bacterial enzyme into an efficient green catalyst
Scientists engineer the CYP107J1 enzyme from Bacillus subtilis into a more practical tool for selective oxidation chemistry.

NewsStarvation triggers reversible epigenetic changes in fish pathogen
What happens to a bacterial pathogen when food runs out—for several months? A new study reveals that Flavobacterium columnare, a deadly aquatic pathogen responsible for columnaris disease in fish, does not change its DNA sequence during prolonged starvation. Instead, it remodels its epigenetic landscape.

NewsProtection for newborns: New treatment aims to prevent meningitis without antibiotics
One of the leading pathogens responsible for meningitis cases in newborn babies is the K1 form of the E. coli bacterium. Now, researchers have developed a triple-pronged approach that seeks to prevent transmission to newborns.

NewsNew study suggests fish gut microbe helps regulate ocean health
New research reveals a potential link between the gut microbes of a fish and global ocean processes, offering new insight into how marine ecosystems help regulate ocean chemistry and the marine carbon cycle.

NewsScientists clarify the interplay between host and gut microbiota in selenium metabolism
In a recent study, researchers used rats to investigate how gut microbiota and the host jointly manage selenium metabolism. They found that gut microbiota actively transform selenium into various metabolites that influence selenium utilization, detoxification, and excretion, and that the host’s selenium intake affects bacterial diversity.

NewsResearch shows plants such as canola, tomatoes and rice reduce iron uptake when stressed by drought
New research has found that plants, ranging from canola to rice to tomatoes, actively shut down their own ability to take up iron when they experience drought. The study questions whether plants send out a ‘cry for help’ when they are stressed by drought to recruit beneficial soil microbes in their roots.

NewsResearchers discover tick protein that may block disease transmission
Researchers have found that ticks produce an exosomal glycine-rich protein that plays a vital role in helping ticks feed and transmit viruses. When they used genetic tools to silence the gene responsible for this protein, ticks lacking the protein struggled to feed effectively and showed reduced body weight after feeding.

NewsSoil scientist awarded $1.6 million NSF grant to study ‘living skin’ of arid ecosystems
A soil scientist has received a $1.6 million, five-year grant from the U.S. National Science Foundation (NSF) to fund her team’s study of how increasing temperature fluctuations impact the biocrust microbiome — the complex, thin-layer microbe community that stabilizes soil, fixes nitrogen and drives nutrient cycling in drylands.

NewsRecent study reveals how bacteria capture a rare type of sugar molecule
Researchers have identified a novel transport protein that binds cyclic β-1,2-glucans, revealing unexpected diversity in bacterial sugar uptake mechanisms.
