NewsScientists explain why methane spiked in the early 2020s
A combination of weakened atmospheric removal and increased emissions from warming wetlands, rivers, lakes, and agricultural land increased atmospheric methane at an unprecedented rate in the early 2020s, an international team of researchers report.

NewsPathogen risk: Removing southern African fences may help wildlife, boost economy
Fences intended to protect cattle from catching diseases from wildlife and other livestock in southern Africa are in disrepair, restrict wild animal migrations and likely intensify human-elephant conflict – but a plan to remove key sections could make both livestock and wildlife safer.

NewsNext generation genetics technology developed to counter the rise of antibiotic resistance
The new Pro-Active Genetics (Pro-AG) tool called pPro-MobV is a second-generation technology that uses an approach similar to gene drives to disable drug resistance in populations of bacteria.

NewsResearchers discover that vaginal bacteria don’t always behave the same way
By analyzing vaginal microbiome data at unprecedented resolution, researchers have identified 25 distinct vaginal microbiome types and demonstrated that bacteria of the same species can differ substantially in their functional potential, thereby affecting how these microbes interact with the body.

NewsA standout solvent for today’s biorefineries
Researchers tested multiple distillable amine-based solvents to see how they performed in pretreatment processes for biomass. They found butylamine was a superior solvent.

NewsTeam finds E. coli, other pathogens in Potomac River after sewage spill
Following one of the largest sewage spills in U.S. history, researchers detected high levels of fecal-related bacteria and disease-causing pathogens in the Potomac River, raising urgent public health concerns and underscoring the risks posed by aging sewer infrastructure.

New vaccine platform promotes rare protective B cells
Based on a virus-like particle built with a DNA scaffold, the approach could generate broadly neutralizing antibody responses against HIV or influenza.

NewsNew study: Immune cells linked to Epstein-Barr virus may play a role in MS
Researchers have found that certain types of CD8+ “killer” T cells — immune cells that destroy damaged or infected cells — are more abundant in people with MS. Some of these killer T cells target EBV, which suggests that the virus may trigger the damaging immune response seen in MS.

NewsFrom ambassadorship to action: Leading a national scientific writing and publishing workshop in the UK
Medical Microbiologist and Antimicrobial Resistance Researcher Dr. Oluwole Owoyemi, ASM Young Ambassador to the UK, reveals why he designed a scientific writing and publishing workshop for early career scientists - and how it went.

NewsCARB-X to support development of typhoid fever diagnostic from Chembio
CARB-X is awarding US$1.8 million to Chembio Diagnostic Systems, Inc. to develop a rapid point-of-care test for the detection of Immunoglobulin A (IgA) antibodies to diagnose acute infection of Salmonella enterica serovar Typhi.

NewsStudy reveals dual forces driving SARS-CoV-2 evolution: Immune pressure and viral fitness
New research clarifies the complex role of neutralizing antibodies in shaping disease outcomes and the evolution of SARS-CoV-2.

NewsOysters play unexpected role in protecting blue crabs from disease
Oysters famously filter their surrounding water, but it turns out they are removing more than algae and excess nutrients. New research shows they can also reduce the spread of disease in nearby marine species, including Chesapeake Bay’s prized blue crabs.

NewsBreakthrough in human norovirus research: Researchers overcome major obstacle to grow and study the virus
Researchers have overcome a major obstacle that limited their ability to continuously grow human norovirus. They identified factors that restrict viral replication and developed a way to overcome them to optimize long-term viral cultivation.
-
NewsNew study reveals a minimalist bacterial defense that disrupts viral assembly
Researchers describe how a single protein named Rip1 recognizes bacteriophages, the viruses that infect bacteria, and cause infected bacteria to die prematurely, thereby ending the chain of transmission.

NewsPreviously unknown viruses discovered in groundwater
Researchers have created a comprehensive picture of viral diversity and function in a groundwater system. They identified over 257,000 viral operational taxonomic units, i.e. viruses at species level, 99 % of which were previously unknown.

NewsResearchers urge focus on child obesity and gut health to reduce risk of diabetes
Researchers are calling for more study of obesity, gut bacteria and metabolic conditions that arise in childhood and adolescence, with an eye to curbing the global rise of type 2 diabetes.

NewsScientists demonstrate first-ever single-shot HIV vaccine neutralization success
Scientists have developed an HIV vaccine candidate that achieves something never before observed in the field: inducing neutralizing antibodies against HIV after a single immunization in nonhuman primates.

NewsRisk for Lyme disease in Ohio is equal to Connecticut, study shows
The risk for being bitten by a tick infected with bacteria that cause Lyme disease is as high in Ohio as it is for those living in Northeast states that have dealt with Lyme disease for over 50 years, according to a new study.

NewsGenes from corn’s wild ancestor change soil microbial community, improve sustainability
Corn bred with genes from wild relatives can reshape soil microbial communities and reduce nitrogen loss — with no yield reduction, according to new research. It’s the first time corn’s genetic makeup has been linked with inhibition of nitrifying and denitrifying bacteria.

NewsWhy aren’t more older adults getting flu or COVID-19 shots?
This winter’s brutal flu season isn’t over, and COVID-19 cases have risen recently too. But a new poll taken in recent weeks shows that vaccination against both viruses lags among people 50 and over, and the US survey reveals key reasons why.
