Phys.org / Scientists build world's most accurate atomic clock
Take a second and turn it into trillions of moments. Measure each one. That's how precisely an atomic clock at Singapore's Centre for Quantum Technologies (CQT) keeps time—and with record-setting accuracy, according to results ...
Phys.org / Aerial maps reveal successful woodland expansion in Scotland's Cairngorms
A University of Cambridge–led team has used aerial surveys across a huge swath of the Cairngorms National Park in Scotland to create detailed 3D maps that show the beginnings of large-scale recovery of native woodland.
Medical Xpress / Decades of aerobic exercise may help older adults age with more resilience
Doctors have long recommended investing in physical health for its potential long-term benefits, especially as we age. Over 30 years, regular exercise might help preserve our functional ability.
Phys.org / Prefer intricate shapes? You may also favor complex melodies
A shape can be considered complex because it has many sides. A complex melody may feature varied pitches and rhythms. Does the mind treat these as separate features, or can it recognize something common beneath their differences?
Phys.org / Crown-of-thorns starfish can help reefs thrive
Crown-of-thorns starfish (COTS) are infamous in the marine world. Their toxin-loaded thorns give them a menacing appearance, and they have a reputation as destroyers of coral reefs. New research from the University of Sydney ...
Phys.org / Bizarre new dinosaur with giant claws discovered in China
It walked on two legs and may have looked like a feathered bear with giant claws. Meet Kayrasaurus changliensis—well, its almost complete skeleton, to be precise.
Phys.org / Central surface density of dark matter agrees with the prediction of a new theory of gravity
A researcher from Sejong University has used a new theory of gravity proposed by Erik Verlinde to predict the observed central surface density of dark matter. The study was published in Physics of the Dark Universe on Sept. ...
Tech Xplore / New robotic hand can walk, press keys and move objects on its own
For many of us, the last—and only—time we've seen a walking hand was Thing in "The Addams Family" movies or TV series. Now there's another. Engineers from the Soft Robotics Lab at ETH Zurich have adapted an off-the-shelf ...
Phys.org / Could negative mass exist and be observed?
Unlike electric charge, as far as we know all mass is positive, and positive masses attract one another. Could negative mass exist, and if so, what would be the ramifications?
Phys.org / Biologists battle over North America's largest crayfish
When Caitlin Bloomer wrestled the massive Crawzilla crawdad—yes, that's its actual common name—out of the muck during a biological survey in Kentucky, she was convinced it was the largest crayfish ever recorded.
Phys.org / Astrophysicists use wave simulations to open a new window on dark matter
Astrophysicists from The University of Hong Kong (HKU), working with a research team led by Beijing Normal University (BNU), have developed a more physically realistic approach to testing how ultralight, or "fuzzy," dark ...
Phys.org / Study reveals how communication sequence strengthens green persuasion
The impact of sustainability messages may depend not only on their content but also on the order in which they are presented. The emotional response created by one message may influence how people interpret the next message ...
