Phys.org / Seal tooth pendant reveals ancient human culture and long-distance trading
The identity of a mysterious artifact found in Devon almost 160 years ago has finally been revealed. New research has identified it as a pendant made from the tooth of a gray seal, which would have been worn by an ancient ...
Medical Xpress / Why smoking may raise dementia risk: Lung exosomes could disrupt brain iron balance
The correlation between smoking and neurodegeneration is well-documented, with one study from 2011 finding that heavy smoking in midlife was associated with a greater than 100% increase in risk of dementia, Alzheimer's and ...
Tech Xplore / Prototype chip could boost efficiency of power management in data centers
In an effort to meet the rising energy demands of data centers, engineers at the University of California San Diego have developed a new chip design that could improve how graphics processing units (GPUs) convert and manage ...
Phys.org / Pollinator-friendly gardens don't have to sacrifice style
For gardeners who love colorful, tidy flower beds, helping pollinators doesn't have to mean going fully wild. A new study from plant biologists at Northwestern University and the Chicago Botanic Garden found that some cultivated ...
Phys.org / Student research on coronal holes improves space weather forecasting
Fast solar winds originating from the sun can have direct impacts on Earth—disrupting systems like GPS, aviation, electrical grids, and satellite and radio communications. A new paper by New Mexico State University astronomy ...
Phys.org / High Mountain Asia's melting glaciers may threaten future water security
Glaciers in High Mountain Asia—a region encompassing the Tibetan Plateau and its surrounding mountain ranges—are shrinking rapidly, endangering water resources for millions of people, suggests a new study. Using satellite ...
Phys.org / Tiny African fish caught climbing to the top of a 50-foot waterfall
For over half a century, people in Central Africa have told tales of the fish seen climbing waterfalls, but these claims have never been officially confirmed. Now, these fish have finally been caught on camera, studied more ...
Phys.org / New research shows how forests can prevent floods of all sizes
As large floods occur more frequently worldwide, many wonder what led to such devastating events. Greenhouse gas emissions from human activities, improper land management and forest removal increase flood frequencies and ...
Phys.org / Early humans in South Africa were quarrying stone as far back as 220,000 years ago
As long as 220,000 years ago—far earlier than previously thought—people quarried rocks for their tools in places they specifically sought out. An international research team led by the University of Tübingen has demonstrated ...
Phys.org / Astronomers thought the early universe was full of hydrogen: Now they've found it
The Eberly Telescope Dark Energy Experiment (HETDEX) has discovered tens of thousands of gigantic hydrogen gas halos, called "Lyman-alpha nebulae," surrounding galaxies 10 billion to 12 billion years ago. Known as Cosmic ...
Phys.org / Human-altered mountains drive most fatal landslides worldwide, analysis finds
A new study reveals that most fatal landslides occur in human-transformed environments. Conducted by an international team of researchers from the University of Vienna, Ankara University, Istanbul Technical University, Bursa ...
Tech Xplore / Leather gets a power upgrade with laser-written microsupercapacitors
Researchers have developed a simple and eco-friendly way to use a laser to turn natural leather into flexible and wearable energy devices. The new approach could lay the groundwork for more sustainable wearable electronics. ...
