Medical Xpress / AI-calculated brain age predicts dementia risk years before doctors can see it
Memory clinics still rely on visual rating scales to assess brain atrophy, yet these tools lack the sensitivity to catch subtle changes associated with early dementia. A measure of how old a person's brain appears on brain ...
Phys.org / Intense light bent out of shape—ultrafast lenses made from gas
Researchers from the MPIK in Heidelberg used an atomic gas as a time-dependent lens to shape and spectrally manipulate intense high-frequency laser pulses. This gas-based optical element could pave the way toward better XUV- ...
Medical Xpress / Common arthritis pill repurposed to boost hair regrowth in alopecia patients
Upadacitinib is a medication widely used for the treatment of rheumatoid arthritis that works by inhibiting Janus kinase (JAK) enzymes, which are involved in signaling pathways that regulate immune responses. Now, scientists ...
Medical Xpress / Compound produced after eating pomegranates targets stiff-heart failure pathway, early tests suggest
A compound produced in the body after eating pomegranates improves heart function by up to 80% in a type of heart failure with limited treatment options.
Medical Xpress / A unified framework to explain one of cancer's major drivers
In a rare pair of papers published back-to-back in the journal Genes & Development, research teams led by senior author Anindya Bagchi, Ph.D., associate professor in the Cancer Genome and Epigenetics Program at Sanford Burnham ...
Phys.org / Shrews exhibit reversible size changes in their skulls and noses to get through the winter
Scientists had previously observed that some species of shrews undergo a form of biological plasticity in which their bodies, skulls, brains and some organs shrink in the winter, then regrow in the spring. Now, a new study ...
Tech Xplore / Holographic laser printing makes 3D shapes—voids and all—in one shot
Researchers at the University of Utah's John and Marcia Price College of Engineering, in collaboration with researchers from The University of Texas at Austin, have demonstrated a new method of 3D printing that avoids the ...
Medical Xpress / Cognition and consciousness arise from analog computations, says new theory
A new theory, published in The Journal of Neuroscience by three scientists at the Picower Institute for Learning and Memory at MIT, offers an explanation of how the brain produces cognition and consciousness: It uses traveling ...
Phys.org / Messy life-producing cellular process caught in action for first time
All living things have a fleet of tiny copy machines that turn instructions from DNA into RNA molecules responsible for helping build proteins that keep organisms alive. One of those nanoscale machines, called eukaryotic ...
Medical Xpress / Gray and white matter jointly shape cognitive aging, new evidence shows
Researchers from the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have found that two distinct types of brain tissue work together to support cognition in ...
Phys.org / Soil methane sink may be larger than thought, three-model analysis finds
Methane-munching microbes in soil might be more important than previously thought, a new study finds. Soil is an important carbon sink, and scientists are still learning much about the diversity of its microbial communities. ...
Phys.org / New measurements explain how silicon and diamond achieve extreme reversible stretching
A research team led by Yang Lu from the Department of Mechanical Engineering at the Faculty of Engineering, The University of Hong Kong (HKU), has uncovered the microscopic physical nature of ultralarge elasticity in covalent ...
