RNA editing enzyme found to trigger neuroinflammation in Parkinson's

Parkinson's disease (PD) is a neurodegenerative disorder in which the α-synuclein protein abnormally aggregates within brain cells, causing neuronal damage.

New three-part antivenom cocktail protects against the world’s deadliest snakes

Scientists developed a groundbreaking antivenom cocktail using antibodies from a hyperimmune human donor and a small-molecule inhibitor that protected mice from deadly bites of 19 diverse snakes. This approach could lead to a universal antivenom for the world’s most dangerous snakes, overcoming the limitations of current species-specific treatments.

Are one-year-olds in Australia eating right? New study reveals nutrient gaps

A study from the ORIGINS cohort in Western Australia assessed the diets of one-year-old children, comparing intake to national guidelines. While most nutrient targets were met, key shortfalls in iodine and excessive sodium intake raised concerns, especially for breastfed infants.

Study shows brain estrogen directly regulates appetite in mice

Researchers in Japan found that estrogen produced within the brain, called neuroestrogen, suppresses appetite and reduces body weight in mice by enhancing MC4R expression. The study also showed that neuroestrogen boosts leptin sensitivity, suggesting new targets for obesity treatment.

MRI technique reveals the heart's functional age

Scientists at the University of East Anglia (UEA) have developed a revolutionary new way of uncovering the 'true age' of your heart using MRI.

HO-1 regulates liver fibrosis in NAFLD through the SIRT1 TGF-β Smad3 pathway

Heme oxygenase 1 (HO-1) has an influential yet insufficiently investigated effect on Sirtuin 1 (SIRT1), a histone deacetylase activated by nicotinamide adenine dinucleotide, which may impact the transforming growth factor-β (TGF-ß)/Smad3 pathway in nonalcoholic fatty liver disease (NAFLD)-related liver fibrosis.

Hairlike electrodes offer a new era for comfortable EEG monitoring

The future of electroencephalography (EEG) monitoring may soon look like a strand of hair. In place of the traditional metal electrodes, a web of wires and sticky adhesives, a team of researchers from Penn State created a hairlike device for long-term, non-invasive monitoring of the brain's electrical activity.

Study uncovers how a mobile genetic element hijacks human cells

Viruses are known to use the genetic machinery of the human cells they invade to make copies of themselves. As part of the process, viruses leave behind remnants throughout the genetic material (genomes) of humans.

Lysosomal lipid peroxidation drives ferroptosis in cancer cells

The duplication and division of cells is critical to keeping all multicellular organisms alive. But the opposite process is equally important: cell death.

Study uses artificial intelligence to classify patient pain archetypes after knee replacement

A study using artificial intelligence to classify patient pain archetypes and identify risk for severe pain after knee replacement has earned a Best of Meeting award at the 50th Annual Meeting of the American Society of Regional Anesthesia and Pain Medicine.

Study uncovers 'cell of origin' of the second most common lung cancer

The 'cell of origin' of the second most common lung cancer and the way that it becomes dominant in the lung have been discovered, in a new study in mice and humans from researchers at UCL, the Wellcome Sanger Institute and the University of Cambridge.

Gut immune cells linked to worsening rheumatoid arthritis

After spending years tracing the origin and migration pattern of an unusual type of immune cell in mice, researchers have shown in a new study how activity of "good" microbes in the gut is linked to rheumatoid arthritis and, potentially, other autoimmune diseases.

COVID-19 leaves longer-lasting symptoms than flu or pneumonia, study finds

A large U.S. cohort study found that post-acute symptoms after COVID-19 vary by initial disease severity, age, sex, and comorbidities. Compared to influenza and pneumonia, long COVID presented with distinct symptom patterns and longer-lasting effects.
