  • Scientists map networks regulating gene function in the human brain May 23, 2024
    A consortium of researchers has produced the largest and most advanced multidimensional maps of gene regulation networks in the brains of people with and without mental disorders. These maps detail the many regulatory elements that coordinate the brain's biological pathways and cellular functions. The research used postmortem brain tissue from over 2,500 donors to map […]
  • Study explains why the brain can robustly recognize images, even without color May 23, 2024
    New research offers a possible explanation for how the brain learns to identify both color and black-and-white images. The researchers found evidence that early in life, when the retina is unable to process color information, the brain learns to distinguish objects based on luminance, rather than color.
  • Study uncovers cell type-specific genetic insights underlying schizophrenia May 23, 2024
    New research provides a map for how the genes known to increase risk of schizophrenia affect specific cells within the brain -- information researchers hope can drive the development of new, effective treatments.
  • A promising approach to develop a birth control pill for men May 23, 2024
    Researchers show in animal models that a novel, non-hormonal sperm-specific approach offers a promising option for reversible human male contraception.
  • Mental disorders may spread in young people's social networks May 23, 2024
    A recently completed study demonstrates that mental disorders may be transmitted between individuals within social networks. The finding was the most evident in the case of mood, anxiety and eating disorders.
  • Gentler cell therapies for blood cancer May 22, 2024
    Researchers have developed an approach to 'deleting' a blood system affected by leukemia while simultaneously building up a new, healthy system with donor blood stem cells. The team reports on the promising results obtained in animal experiments and with human cells in the laboratory.
  • Adhesive coatings can prevent scarring around medical implants May 22, 2024
    Engineers have found a way to eliminate the buildup of scar tissue around implantable devices, by coating them with a hydrogel adhesive. The material binds the device to tissue and prevents the immune system from attacking the device.
  • One in two children with ADHD experience emotional problems May 22, 2024
    Scientists have shown that problems regulating emotions -- which can manifest as depression, anxiety and explosive outbursts -- may be a core symptom of attention deficit hyperactivity disorder (ADHD).
  • Extreme temperatures may increase risk of stroke mortality, especially in low-income countries May 22, 2024
    Extreme heat and extreme cold are both associated with increased risks of death from ischemic and hemorrhagic stroke, according to a new study. The researchers found that the link between extreme temperatures and stroke mortality was stronger in low-income countries than in high-income countries.
