Phys.org / Earliest Americans specialized in megafauna hunting from Alaska to South America, analysis of 50 sites reveals
New research led by a University of Alaska Fairbanks archaeologist reveals that the earliest Native Americans had highly specialized diets, primarily hunting the largest animals on the landscape, and they targeted these megafauna ...
Phys.org / Scourge of satellites lighting up the sky could be mitigated with help of ultra-black coating
Astrophysicists working to tackle the growing impact of satellite constellations have pioneered a new ultra-black coating as one possible way to mitigate the problem.
Phys.org / BC and Alberta fall behind on fracking safety distances for residents
In May, Prime Minister Mark Carney announced plans to double the capacity of Canada's electricity grid by 2050, using natural gas in the name of "powering Canada strong." Almost all Canadian natural gas these days is derived ...
Medical Xpress / BCG vaccine may rewire brain immunity, shift Alzheimer's markers over 12 months
New research led by Mass General Brigham investigators suggests that the Bacillus Calmette-Guérin (BCG) vaccine—which is delivered through the skin to prevent tuberculosis—may remodel the human brain's immune environment, ...
Medical Xpress / Dual-mobility hip replacement implant can lower dislocation risk by 70%
A new type of hip replacement implant reduces the risk of joint dislocation after surgery by 70%, according to a new study involving 1,600 patients across 44 hospitals in Sweden and the UK, published in The Lancet. The new ...
Medical Xpress / Popular GLP-1 weight loss drugs are being misused by people struggling with eating disorders, research reveals
Glucagon-like peptide-1 receptor agonists (GLP-1 RAs), such as Ozempic or Wegovy, have revolutionized type 2 diabetes and weight-loss management, but they have also led to some unfortunate outcomes. A recent study in JAMA ...
Science X / Built-in 'antenna' may help cells sense a healing spark to guide repair after injury
When skin is wounded, it doesn't just send out chemical distress signals; it also generates a subtle electrical field. This "electric beacon" forms as the usual voltage across the tissue collapses, creating a guiding current ...
Tech Xplore / Blame the model, not the machine—better data helps 3D-printed metamaterials match predictions
Additive manufacturing, such as 3D printing, provides an excellent opportunity to design metamaterials: materials with an engineered structure that leads to desired properties such as, for instance, resistance to vibrations. ...
Tech Xplore / Giving drones a sense of 'pain' could help them predict instability before it happens
Imagine you're running and you sprain your ankle. The pain makes you gingerly limp the rest of the way home. This is a great example of how nature adapts to failures in a system. The pain tells you: "If you continue running ...
Phys.org / New biosensor reveals rare lipid gathers in membrane hotspots during cell stress
Inside every cell are lipid molecules that make up cellular membranes, helping organelles communicate and respond to stress. Researchers have struggled to observe lipids in action because current detection tools lack sufficient ...
Phys.org / Fish in a polluted Mexican river may mate with the wrong species, leading to hybrid offspring
The byproducts of modern society appear to be messing with the love life of two tiny fish species that have long coexisted in Mexican rivers.
