Medical Xpress / How sugar fuels sight: Glucose metabolism linked to epigenetic and gene expression changes in the retina
National Eye Institute (NEI) scientists have found that the way the retina metabolizes glucose directly controls which genes get switched on and off in light-sensing photoreceptors. The findings suggest that metabolic disruptions ...
Phys.org / A chemical failsafe can save crops from disease without crushing growth
Salicylic acid, the active molecule in aspirin and some acne medications, is a hormone in plants that is essential for immunity, but it's a double-edged sword: Too much can cause autoimmunity and stunt growth. In a study ...
Phys.org / Watermelon super-pangenome paves the way for precision breeding
Watermelon is a quintessential summertime fruit, evoking images of warm, sunny afternoons and cookouts with friends and family. You can easily picture its striped, green rind and pink flesh, imagine the delicate crunch as ...
Medical Xpress / Third Briton has suspected hantavirus after cruise outbreak: health agency
A third British national has been diagnosed with suspected hantavirus linked to a cruise ship outbreak, health officials said Friday.
Tech Xplore / 3D-printed interlocking electrodes demonstrate optimization potential for energy storage
Good electrochemical energy storage (EES) devices such as rechargeable batteries and supercapacitors can store a lot of energy and release it quickly, but these design goals are often at odds with each other. Using design ...
Medical Xpress / The effects of child abuse may be connected to changes in development, body regulation, study suggests
Children who experienced abuse or neglect displayed disrupted development and decreased ability to maintain stable function of internal bodily systems, according to a new study led by researchers in the Penn State Department ...
Phys.org / Scientists map genetic switches on mosquito reproductive genes, advancing tools to fight disease
Scientists at Keele University have created the first detailed map of the genetic "switches" that control reproduction in disease-carrying insects such as Anopheles gambiae, the mosquito species most responsible for malaria ...
Medical Xpress / Ultrafast MRI uncovers brain signal direction: New scan may help decode autism, Alzheimer's and hallucinations
Researchers at the Champalimaud Foundation in Lisbon have for the first time managed to identify with an imaging technique whether nervous impulses in the brain of rats are flowing in a "bottom-up" (feedforward), carrying ...
Medical Xpress / A brain mechanism may help slow Parkinson's disease—but only in females
Scientists have identified a protective brain pathway that may help slow the progression of Parkinson's disease by strengthening the brain's own dopamine-producing neurons, but the positive effect was only observed in females.
Phys.org / Chromatin tracking reveals two motion modes that help control gene expression
Gene expression is controlled, in part, by the interactions between genes and regulatory elements located along the genome. Those interactions depend on the ability of chromatin—a mix of DNA and proteins—to move around within ...
Medical Xpress / Two-pronged phage treatment counters resistance in Mycobacterium abscessus lung infections
Scientists from A*STAR Infectious Diseases Labs (A*STAR IDL), Nanyang Technological University, Singapore's Lee Kong Chian School of Medicine (LKCMedicine), the National University of Singapore (NUS), and international collaborators ...
Medical Xpress / WHO warns of more hantavirus cases in 'limited' outbreak
The World Health Organization said Thursday that more hantavirus cases could emerge after the disease killed three passengers from a cruise ship, but it expected the outbreak to be limited if precautions were taken.
