NewsBiochar and microbe synergy: a path to climate-smart farming
Researchers conducted a global analysis to obtain a full picture of the environmental and agricultural benefits of biochar, which is shown to be beneficial to soil health and microbes.

NewsWere our blue oceans once green?
Scientists find evidence that our oceans used to be green, suggesting that this may be a sign of primitive life, including that on alien worlds. The study suggests that cyanobacteria once flourished in green seas.

NewsProbiotic may improve sleep quality: new research findings
A recent study has identified a potential new approach to managing sleep disorders. The research focuses on the role of S-adenosylmethionine (SAM)-producing probiotics in regulating sleep and circadian rhythms.

News‘It’s a shot, not a vaccine like MMR’: New skepticism prompts call for action
This ‘vaccine is not a vaccine’ is a new, previously unreported type of vaccine-specific scepticism, and it arose only during the COVID-19 pandemic. However, it might, according to the researchers, also apply to the flu vaccine.

NewsScientists zoom in on structure of still lethal Ebola virus
The first high-resolution visualisation of the Ebola virus nucleocapsid provides detailed insights into the interactions within the nucleocapsid complex, unveiling the relationship between molecular interactions and functional regulation.

NewsSea buckthorn extract exerts anti-free radical, antibacterial and whitening effects on skin
Sea buckthorn flavonoids exhibited excellent antimicrobial, anti-inflammatory and whitening effects in a new study. The inhibitory effect of sea buckthorn flavonoids on Propionibacterium acnes were assessed by plate antibacterial assays.

NewsProposed cuts to foreign aid could result in millions of HIV deaths, new modelling study estimates
New modelling analysis suggests that proposed funding cuts by major donor countries to foreign aid could undo decades of progress made to end HIV/AIDS as a public health threat and new infections and deaths could surge back to levels not seen since the early 2000s.

NewsHow Zika virus knocks out our immune defenses
Scientists have made striking discoveries regarding the different infection mechanisms of Zika and dengue virus of the same viral family. These understandings pave the way for vaccine development to combat flaviviruses with similarities.

NewsScientists unlock frogs’ antibacterial secrets to combat superbugs
Researchers exploited natural peptides derived from frogs and improved their structural designs as antibiotic candidates, which are effective against complex mock bacterial communities of drug-resistant pathogens in preclinical tests, sparing beneficial microbiota and human cells.

NewsResearchers find live hantavirus is carried in various New Mexico small mammal species
A study was carried out to find out the reasons why human cases of the sin nombre hantavirus were concentrated in one particular region of New Mexico, even though the virus was found in 30 species of rodents and small mammals endemic to a different region.

NewsBreakthrough as researchers discover new class of antibiotics
Researchers have identified a strong candidate to challenge even some of the most drug-resistant bacteria on the planet: a new molecule called lariocidin.

NewsCorrecting imbalance with the gut microbiota after stroke could reduce brain inflammation
An imbalance in ligands, which are molecules produced by the body and the gut microbiota, can affect a key receptor protein that plays a role in brain inflammation after stroke, according to researchers.

NewsAntibiotic exposure in infancy may boost Type 1 diabetes risk - but microbiota can help
Exposure to antibiotics during a key developmental window in infancy can stunt the growth of insulin-producing cells and may boost risk of diabetes later in life. But the research pinpoints specific microbes that may help those critical cells proliferate in early life.

NewsThe gut microbiota-metabolites-brain axis mediates social behavior dysfunction following anaesthesia
New research shows that the anaesthetic Sevoflurane (Sev) influences social functioning via the gut-brain axis, with microbiota-derived bile acids serving as critical mediators in this pathway.
-
NewsTadpoles try to flee dangerous virus in their pond by growing much faster than normal
A new study shows that larvae of wood frogs respond to the presence of a deadly ranavirus by growing and maturing precociously. In response to ranavirus, tadpoles change their growth, development, and resource allocation, which may help them tolerate the energetic demands of infection or escape risky environments to avoid infection.

NewsC. diff uses toxic compound to fuel growth advantage
The pathogen C. diff — the most common cause of health care-associated infectious diarrhea — can use a compound that kills the human gut’s resident microbes to survive and grow, giving it a competitive advantage in the infected gut.

NewsGrowing body of evidence links HPV with heart disease
In addition to causing several types of cancer, human papillomavirus (HPV) appears to bring a significantly increased risk of heart disease and coronary artery disease, according to a study.

NewsProbe into human cervical stem cells shows lactic acid bacteria can prevent cervical cancer
Researchers have revealed the identity and differentiation process of human cervical stem cells in a world first study. The results showed that lactic acid bacteria can inhibit the development of cervical cancer.

NewsResearchers achieve de novo biosynthesis of plant lignans using synthetic yeast consortia
Researchers have achieved the biosynthesis of the antiviral ingredient lignan glycoside in yeast Saccharomyces cerevisiae. By mimicking the spatial and temporal regulation of plant biosynthesis, they designed a system with obligated mutualism, enabling metabolic division of labor among different yeast strains.

NewsSusceptibility to bovine TB in cattle traced to key genes
A new study identifying genetic factors contributing to bovine tuberculosis (bTB) susceptibility has found several key genes and pathways involved in the bovine response to Mycobacterium bovis, the causative agent of the disease in cattle.
