New soft wearable device could support at-home sleep monitoring
Good sleep is essential for brain health. During sleep and rest, the glymphatic system, the brain's waste-clearing process, helps remove metabolic waste that accumulates during waking hours. This activity is linked to memory processing, cognitive function and neural recovery. Whe
Hepatitis E viruses mutate early during infection
Knowing how viruses change in the initial weeks of an infection can provide important information about their adaptability. Researchers from the Departments of Molecular & Medical Virology and Translational & Computational Infection Research at Ruhr University Bochum, Germany, ha
Mouse study uncovers how transcription factors HIF1α and HIF2α regulate different aspects
Skeletal muscles—responsible for movement, joint stabilization and postural support—are highly metabolically active and heavily reliant on oxygen during physical activity. However, conditions such as high-intensity exercise or sustained exertion frequently expose skeletal muscles
Enhancing safety of advanced radiotherapy cancer treatments for children
Researchers from the National Physical Laboratory (NPL), Heidelberg University Hospital and the German Cancer Research Center (DKFZ) have published new findings that improve understanding of secondary neutron exposure during pediatric ion beam therapy, an important area of study
Ureters stay visible for hours with dye designed to vanish through kidneys
A cross-disciplinary research team led by Hongjie Dai, director of the Materials Institute of Life Sciences and Energy (MILES) at the University of Hong Kong (HKU) in Shenzhen, has developed a promising near-infrared (NIR) fluorescent dye for potential clinical use in ureter imag
Heat exposure during pregnancy and infancy may influence children's brain development
Exposure to high temperatures during pregnancy and early infancy is associated with slower growth of the thalamus later in childhood, according to a study led by the Barcelona Institute for Global Health (ISGlobal), a center supported by the "la Caixa" Foundation. The findings, p
New insights into neuron–microglia interactions during brain aging
Researchers at the University of Tsukuba have identified small nuclear fragments known as micronuclei while studying neurons in aged mice. They demonstrated that microglia—the brain's resident immune cells—take up these micronuclei, leading to changes in microglial morphology and
Keeping moms in the game: FIFA launches guide for pregnant and post-partum players
Soccer players who are pregnant or have recently given birth can kick off the season with more confidence, using a new FIFA tool developed in collaboration with a University of Alberta researcher. Two decision aids, one for playing during pregnancy and one for returning to the ga
Hormonal changes during puberty linked to emotional distress in young girls
Testosterone may play a bigger role in the emotional development of girls entering puberty than previously thought, according to new research from the University of Georgia published in Psychoneuroendocrinology. Greater changes in the hormone were linked to more emotional difficu
Trial finds combined exercise-nutrition intervention safe but not more effective in ICU
A new national clinical trial is helping reshape the future of recovery research for critically ill patients, providing important new evidence about how rehabilitation and nutrition interventions should be delivered during severe illness and informing the next generation of resea
Pregnancy may flag future heart and metabolic risk, even without major complications
Pregnancy can be a warning light. Rutgers researchers found that cardiovascular health during pregnancy was linked to how soon women were later diagnosed with chronic hypertension or metabolic conditions after giving birth.
