Medical Xpress / Night shifts aren't just tiring, they can be deadly: Disrupted sleep cycles linked to aggressive breast cancer
Working the night shift, frequently flying across time zones or keeping an irregular sleep schedule does more than just leave us exhausted; it can fuel the risk of aggressive breast cancer. Exactly how and why this happens ...
Medical Xpress / Brain's 'pulse generators' grow and shrink as memories are formed, study finds
Memories and learning processes are based on changes in the brain's neuronal connections, and as a result, in signal transmission between neurons.
Medical Xpress / To flexibly organize thought, the brain makes use of space
Our thoughts are specified by our knowledge and plans, yet our cognition can also be fast and flexible in handling new information. How does the well-controlled and yet highly nimble nature of cognition emerge from the brain's ...
Medical Xpress / New ALS drug stabilizes decline with a trend toward improved strength and mobility for some
Historically, people with amyotrophic lateral sclerosis (ALS) experience a relentless decline in neurological function that eventually robs them of the ability to move, speak, eat or breathe. Now, researchers from Washington ...
Medical Xpress / Scientists grow mini brains to uncover cells behind autism-related brain overgrowth
A new study in the lab of Jason Stein, Ph.D., modeled brain development in a dish to identify cells and genes that influence infant brain growth, a trait associated with autism.
Medical Xpress / Fathers' microplastics exposure tied to their children's metabolic problems
A study led by biomedical scientists at the University of California, Riverside, has shown for the first time that a father's exposure to microplastics (MPs) can trigger metabolic dysfunctions in his offspring. The research, ...
Medical Xpress / Molecular difference in autistic brains may explain signaling imbalance
Yale School of Medicine (YSM) scientists have discovered a molecular difference in the brains of autistic people compared to their neurotypical counterparts.
Medical Xpress / Modified tau thwarts aggregation in neurodegenerative disease—while retaining its biological function
A designer version of the tau protein, developed by a team led by UT Southwestern Medical Center researchers, maintains its biological function while resisting aggregation, a pathological trait linked to neurodegenerative ...
Medical Xpress / Inflammation fuels one of the most aggressive forms of lung cancer
Small cell lung cancer (SCLC) is one of the most aggressive forms of lung cancer, with a five-year survival rate of only 5%. Despite this poor prognosis, SCLC is initially highly responsive to chemotherapy. However, patients ...
Medical Xpress / System replicates womb lining to 'listen in' to embryo-mother interactions during implantation
By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and Stanford University have been able to study the implantation of human embryos, opening up this enigmatic ...
Medical Xpress / Birth control can ease PCOS symptoms without added heart or diabetes risk, clinical trial finds
Birth control pills, taken alone or paired with the drug metformin, did not raise the risk of metabolic syndrome, a precursor of heart disease and diabetes in women with polycystic ovary syndrome (PCOS) even if those women ...
Medical Xpress / Signature neural patterns may help predict recovery from traumatic brain injury
After traumatic brain injury (TBI), some patients may recover completely, while others retain severe disabilities. Accurately evaluating prognosis is challenging in patients on life-sustaining therapy.
