Phys.org / How climate change may amplify the impact of earthquakes in the Arctic
Permafrost refers to permanently frozen ground. The rock is held together by ice, much like cement binds concrete. However, when the ice thaws, the ground becomes weak and unstable. During an earthquake, this can trigger ...
Medical Xpress / Transition to cleaner heating can lower blood pressure
An environmental policy designed to improve air quality also has benefits for cardiovascular health, a new McGill-led study finds.
Medical Xpress / Healthy lifestyle in middle age adds happiness alongside longevity to old age
In a 50-year follow-up study, men with low cardiovascular risk in their 40s maintained their functional capacity, happiness and quality of life better than others as they aged.
Phys.org / Scientists observe Einstein's gravity in the quantum world
An international team including Nobel Prize-winning physicist Professor Sir Roger Penrose has observed a long-predicted effect of gravity on a falling quantum object for the first time. The result shows that a fundamental ...
Medical Xpress / Scientists reveal how blood cells release key signaling lipid
Scientists from the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine), and St. Jude Children's Research Hospital in the United States have discovered how blood cells release an important signaling ...
Phys.org / AI helps reveal the immersive sensory experiences of ancient Etruscan tombs
The Etruscan painted tombs in Tarquinia, Italy, date to the first millennium BCE and are known for their vivid scenes of music, feasting, processions and the afterlife. While these tombs have been extensively studied, archaeologists ...
Phys.org / Not all eggs are the same—uncovering a tropical parasite's secret weapons
A team of scientists from the Faculty of Science at Charles University has achieved a major breakthrough in research into schistosomiasis, a serious tropical disease affecting more than 250 million people worldwide. Using ...
Phys.org / Reversible electric control unlocks persistent chiral phonon states
Atoms in a material are rarely still. They jiggle back and forth in collective lattice vibrations known as phonons. Their motion can also carry a rotational element: In 2023, scientists at PSI experimentally proved the existence ...
Phys.org / Slender crystal's blue-to-yellow glow could make invisible forces visible
Applying pressure to luminescent organic crystals usually brings molecules closer together and weakens their fluorescence. Materials that instead brighten and undergo a large color change are rare, and clear design principles ...
Phys.org / Why 'you're smart' can backfire: Young children may cheat more after ability praise
Parents and teachers might think telling kids "they're smart" is a helpful way to build self-confidence and support positive development.
Medical Xpress / Diabetes drug metformin could be repurposed to help slow aging mechanisms
Metformin, a widely prescribed, safe and inexpensive drug for type 2 diabetes, is a first-line treatment that lowers blood sugar and improves the body's response to insulin. The drug appears to trick cells into sensing an ...
Phys.org / New model measures economic risks solar storms pose to US power grid
In 1967, a solar storm nearly triggered World War III by jamming early-warning radar systems in the United States, causing U.S. leaders to think the Soviet Union was responsible. Though society averted catastrophe thanks ...
