Phys.org / DESI releases biggest 2D map of the universe
Hold on to your telescopes: The DESI Legacy Imaging Surveys team has released the largest-ever 2D color map of the universe. The 5.6-trillion-pixel map contains nearly 4 billion celestial objects, primarily stars and galaxies. ...
Phys.org / Europe swelters under fresh wave of extreme heat
Millions of people across Europe—particularly in France, Italy, Spain and Britain—baked through a new wave of extreme temperatures Thursday as the continent's latest heat wave picked up.
Phys.org / Ancient Colombians built huge water system without centralized rule, archaeologists say
Communities living in Colombia thousands of years ago achieved an engineering wonder of the world based on cooperation among family groups without top-down government, a new study shows. Archaeologists argue that policymakers ...
Dialog / A surprising pathway that lets the striatum talk directly to the auditory cortex
For decades, neuroscientists have thought about communication between the cerebral cortex and the basal ganglia in a fairly linear way. The cortex sends information into the basal ganglia, where that information is processed ...
Medical Xpress / Health systems failing smokers in poorest nations, experts say
Only 13 low- and middle-income countries offer smokers the full support needed to help them quit, leaving around 1.3 billion people without access to effective care, according to a new study.
Medical Xpress / Detection of optic nerve inflammation enables earlier multiple sclerosis diagnoses
Multiple sclerosis (MS) is the most common chronic autoimmune disease of the central nervous system. An early and accurate diagnosis is crucial for improving the effectiveness of treatment and reducing nerve damage. To standardize ...
Medical Xpress / School-based hybrid tools can improve youth well-being, but research gaps persist
Children and youth face rising mental health challenges in an increasingly digital world, especially those from marginalized populations. A new systematic review and meta-analysis of universal digital mental health interventions, ...
Phys.org / Rechargeable nickel reservoir enables nitrile production in organic solvents
Inspired by pumped-storage hydropower, a nickel-based redox reservoir enables spontaneous nitrile synthesis in organic solvents, while hydrogen gas is produced separately.
Tech Xplore / New research reveals gaps in passkey security tools for abuse survivors
Passkeys are touted as safer than traditional passwords. But for people targeted by intimate partner abuse, they can often be more dangerous. Someone with access to their partner's computer and password could set up their ...
Phys.org / One-step synthesis of catalysts that turn carbon dioxide into useful methane
A simple flame-synthesis method can produce highly active catalysts for converting carbon dioxide into methane, as reported by researchers from Science Tokyo. The team used flame-assisted spray pyrolysis to manufacture nickel–cerium ...
Phys.org / How multilayer nanocoatings dissipate energy at the nanoscale to prevent failure
An international research team including Alexander Korsunsky from the Skoltech Engineering Center has, for the first time, directly measured mechanical stresses at the contact between a diamond indenter and a complex nanostructured ...
Phys.org / 'Imposing ignorance': US climate science under siege
A benchmark U.S. report on the fast-changing state of the Arctic has been canceled. The nation's top research body has removed a chapter on global warming from a reference manual for judges.
