NewsMethane emissions maximised by global warming
A new study explains how increases in natural methane emissions will be maximised under future climate warming. It showed that while methane consuming microbes do work harder under warmer conditions, they cannot fully check the extra methane being produced with warming.

NewsNew tool quickly sequences hantavirus genome
The genetic diversity of hantavirus and the low levels of virus typically found in patient samples make sequencing its genome particularly challenging. Researchers have developed a new, effective, and low-cost way to carry out whole genome sequencing for hantaviruses.

NewsDentistry researchers testing oral bacteria transplants to cure bad breath
To rebalance the oral microbiome and cure chronic halitosis, researchers are embarking on a first-of-its-kind experiment. These clinical trials transplant bacteria and other microbes from healthy donors into patients with halitosis. If successful, the healthy microbiota will crowd out the bad and patients’ bad breath will improve.

NewsProfessor Kaneko’s sake and wine earn honors at French Japanese Sake Competition for second consecutive year
At “Kura Master,” a Japanese sake competition held in France for French consumers since 2017, “Aldebaran,” a wine produced from grapes grown in the city of Ibara, in Okayama Prefecture, and supervised by Professor Akihiro Kaneko, won a Gold Award in the Muscat Bailey A category.

NewsBiochar can reshape how soils respond to warming, but the effect depends on the soil
A new study shows that biochar can change how strongly soil nitrous oxide emissions respond to rising temperatures. But the effect is not one-size-fits-all. The study found that nitrous oxide emissions increased with warming in both agricultural soil and forest soil, but forest soil was more temperature-sensitive than agricultural soil.

NewsMaternal RSV vaccine cuts infant hospitalizations by 70%
A study has found that vaccination against respiratory syncytial virus (RSV) during pregnancy reduced the risk of hospitalization in young infants by nearly 70%. It provides early real-world evidence from U.S. clinical care, showing that administering one dose of the maternal RSV vaccine (RSVpreF vaccine) reduces hospitalization related to RSV in young infants.

NewsFlu drugs show promise against cognitive decline
A class of flu drugs may reduce cognitive decline and premature aging in people living with chronic viral infection. Scientists identified a new biological culprit: the degradation of protective sugar molecules in our bodies, known as glycans, that normally help keep inflammation in check.

NewsData from patients hospitalised with COVID-19 made available to the scientific community
The DIVINE study database has been published. The cohort includes clinical information from 5,813 patients hospitalised with COVID-19 during four waves of the pandemic, between March 2020 and August 2021, across five hospitals in the southern metropolitan area of Barcelona.

NewsResearcher discovers single-celled organism that transforms into cannibalistic supergiant
Researchers have discovered a microscopic organism that can transform into a cannibalistic ’supergiant’ that drastically changes size, shape, and behavior, and abandons filter-feeding to hunt and consume their genetically identical relatives.

NewsFrom spider silk to science: a new way to access hidden fungal diversity
A new study suggests that spider webs - particularly those incorporating environmental debris - can serve as natural, non-destructive collectors of fungal material in agricultural ecosystems. The findings show that viable fungi can be recovered from these structures, including lineages that may represent previously undocumented diversity.

NewsFever and chills can make respiratory diseases more contagious
A new study reveals that when the difference between body temperature and the ambient temperature is greater, the clouds of particles generated by coughing or sneezing disperse more and maintain a higher concentration.

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.

NewsOrganized microbial ‘workforces’ keep Earth’s underground biosphere running
By studying life deep inside a former gold mine, scientists uncovered evidence that Earth’s hidden biosphere operates less like a random collection of microbes and more like an organized workforce. From site to site, the ecosystems were incredibly different from one another but largely stable through time.

NewsNew model could help track deadly viruses back to their source
A new predictive model could help scientists more efficiently identify the reservoirs of emerging zoonotic viruses and dangerous pathogens like Ebola that can spill over from animals into humans. It relies on detailed information collected on suspected reservoir species to identify key windows.

NewsArctic river deltas at risk from mounting pressures
Researchers have performed a detailed calculation of the amount of carbon stored in permafrost in Arctic river deltas. In a new study, they point out the risks endangering the storage function of these highly sensitive landscapes due to rapid climate change.

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.

NewsIron-modified biochar turns soil oxygen into a cleaner for antibiotic pollution
Antibiotic residues in agricultural soils are an emerging environmental concern, with potential impacts on soil health, crop safety, and the spread of antimicrobial resistance. A new study reports on an iron-modified biochar that helps soil use its own oxygen and iron chemistry to break down sulfamethoxazole.

NewsResearchers develop new vaccine adjuvant that could make it easier to eradicate polio
Researchers have now come up with a way to modify the injectable polio vaccine so that it can also promote a mucosal immune response. This vaccine could help to achieve polio eradication while avoiding the risks of the oral polio vaccine.

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.
