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.

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.

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.

NewsLarge study uncovers specific impacts of flooding on older adult health
New research examining 17 years of data from Medicare hospitalization claims and major flooding events finds increased rates of skin diseases, nervous system diseases, and injuries or poisonings among adults aged 65 and older following major floods.

NewsStudy highlights the severity of acute necrotizing encephalopathy in kids with the flu
For a small subset of children, influenza can trigger a rare but serious complication called influenza-associated acute necrotizing encephalopathy (ANE). Now, findings of a multicenter study suggest that ANE is often fatal in these children — despite intensive treatment.

NewsClinical trial finds safe, effective treatment for children with severe post-Covid syndrome
Researchers have discovered that a drug designed to treat Celiac disease supported a more rapid return to normal activities for patients following COVID. A small, randomized clinical trialfound the oral drug larazotide was both safe and effective in treating children with MIS-C.

NewsGut microbes: How many molecules influence our body?
Researchers have precisely quantified how many molecules are produced by gut bacteria and arrive in the body every day, enabling them to calculate how many gut bacteria are used up and regenerated each day.

NewsHow bacteria use a protein associated with Alzheimer’s to fight off threats
Amyloids are perhaps best known as a key driver of Alzheimer’s disease. According to new research, these oft-maligned proteins also serve a critical role for bacteria in our environment, enabling them to fight off other “predatory bacteria.”
