NewsNew research reveals ancient alliance between woody plants and microbes has potential to protect precious peatlands
New research shows that during historic periods of drying the growth of woody plants in a subtropical Chinese peatland improved the quality of organic matter and suppressed decomposing microbial activity.

NewsGreat Barrier Reef more volatile with sharp declines in coral cover
Hard coral cover across the Great Barrier Reef has declined substantially from the high levels of recent years back to near long-term average levels, underscoring a new level of volatility.

NewsImperfect underground processes help filter wastewater in Florida Keys
Researchers find that microbial and other processes do not completely clear wastewater shallowly injected into groundwater of potentially harmful contaminants.

NewsStudy finds gaps in evidence for air cleaning technologies designed to prevent respiratory infections
A new study finds that although many technologies claim to clean indoor air and prevent the spread of viruses like COVID-19 and the flu, most have not been tested on people and their potential risks are not yet fully understood.

NewsRegional differences in antibiotic use in newborns
There are relatively large regional differences in Sweden in the proportion of newborns receiving antibiotics for suspected sepsis, according to a study. The researchers want to call attention to overuse as well as highlight good examples.

NewsNew study illuminates how diatoms thrive in — and light up — the Southern Ocean
An area of the remote Southern Ocean that’s long confused ocean color satellites by reflecting large amounts of turquoise-colored light appears to be full of silica-rich diatoms, according to a new study. There is also evidence in these polar waters of coccolithophores.

NewsSmall protein, big impact: Insights into how bacteria stabilize a key outer membrane complex
Researchers reveal that a remarkably small protein is essential for the maturation of a component of the lipopolysaccharide transport system.

NewsResearchers debunk long-standing concern about flu treatment in children
Researchers have debunked a long-standing theory about oseltamivir, known as Tamiflu. Oseltamivir treatment during flu episodes was associated with a reduced risk of serious neuropsychiatric events, such as seizures, altered mental status and hallucination.

NewsWhy killer cells can lapse into ‘exhausted’ CD8+ T cells that no longer can stem disease
In a detailed study of exhausted T cell subsets researchers show that a transcriptional repressor called Gfi1 is a key regulator of the subset formation of exhausted CD8+ T cells and may offer a key to reducing exhaustion.

NewsNew study: Powerboats can impact lakes below the surface, stimulating algaL growth
Large surface waves produced by powerboats are a mainstay for recreational watersports. A new study shows that beneath the surface, factors such as propeller thrust and other types of waves can impact delicate lakebed ecosystems.

NewsOrganized scientific fraud is growing at an alarming rate, study reveals
Although concerns around scientific misconduct typically focus on lone individuals, a study of scientific fraud has uncovered sophisticated global networks of individuals and entities, which systematically work together to undermine the integrity of academic publishing.

NewsNew mega RNA virus may hold the key to mass oyster die-offs
Scientists have discovered a previously unknown virus in farmed Pacific oysters during a mass die-off in B.C., Canada. The discovery serves as a reminder that growers should exercise caution when moving young oysters, to prevent potential spread of pathogens.

NewsResearchers discover cause of sea star wasting disease
Researchers have revealed the cause of sea star wasting disease (SSWD). The marine epidemic has killed billions of sea stars—representing more than 20 different species from Alaska to Mexico. SSWD is considered the largest marine epidemic ever documented in the wild.

NewsBrewed chicken protein made by precision fermentation tested in pet food
In a groundbreaking new project, scientists used precision fermentation to produce brewed chicken protein and evaluated it for use in pet food. Dogs that consumed the protein in their kibble during a six-month study had beneficial digestive effects, they found.
-
NewsScientists discover how leukemia virus stays hidden in the body
A research team has discovered how the human T-cell leukemia virus type 1 (HTLV-1) silently persists in the body. Their findings identify a previously unknown genetic “silencer” element that keeps the virus in a dormant, undetectable state.

NewsStatistical modeling can help tackle neglected tropical diseases among migrant populations
A study of migrants in Italy has shown how statistical modelling can help improve the identification of Neglected Tropical Disease (NTD) infections.

NewsQ&A: Why do symptoms linger in some people after an infection?
A new review highlights that long COVID and ME/CFS share many of the same biological problems such as inflammation in the brain, issues with how cells produce energy, and problems with the immune system.

NewsHelping me, inhibiting you: Analysis of interactions between intestinal microbiota
Researchers have analyzed the interactions between two bacteria that make up intestinal microbiota. While Faecalibacterium prausnitzii inhibits the growth of Fusobacterium varium, F. varium promotes the growth of F. prausnitzii.

NewsSkin test reagent proves effective and safe for TB diagnosis in children
A new class of skin test reagents based on Mycobacterium tuberculosis (MTB)-specific antigens has been developed. A phase III clinical trial suggests that C-TST is an effective and safe option for diagnosing pediatric TBI.

NewsScientists pinpoint optimal dose of methylprednisolone for treating severe Mycoplasma pneumoniae pneumonia
Investigators have compared the efficacy of low- versus high-dose of methylprednisolone in preventing pulmonary lesions in children with severe Mycoplasma pneumoniae pneumonia.
