Phys.org / Scientists may have solved 66 million-year-old mystery of how Earth's greenhouse age ended
A 66 million-year-old mystery behind how our planet transformed from a tropical greenhouse to the ice-capped world of today has been unraveled by scientists. Their new study has revealed that Earth's massive drop in temperature ...
Phys.org / How fire, people and history shaped the South's iconic longleaf pine forests
For thousands of years, one tree species defined the cultural and ecological identity of what is now the American South: the longleaf pine. The forest once stretched across 92 million acres from Virginia to Texas, but about ...
Phys.org / Hibernating hamsters maintain muscle cells by suppressing muscle regeneration, study shows
Skeletal muscle stem cells in hibernating Syrian hamsters preserve their ability to function by suppressing their activation during the hibernation period, a research team led by Hiroshima University has shown. This insight ...
Medical Xpress / Inactivating the SARS-CoV-2 virus using focused sound waves
A team of researchers from the Ministry of Health in Kuwait has successfully demonstrated the destruction of SARS-CoV-2 virus particles through exposure to high-frequency sound waves, marking a promising advance in non-pharmacological ...
Phys.org / Watching atoms roam before they decay
Together with an international team, researchers from the Molecular Physics Department at the Fritz Haber Institute have revealed how atoms rearrange themselves before releasing low-energy electrons in a decay process initiated ...
Phys.org / The shape of things to come: How spheroid geometry guides multicellular orbiting and invasion
As organisms develop from embryos, groups of cells migrate and reshape themselves to form all manner of complex tissues. There are no anatomical molds shaped like lungs, livers or other tissues for cells to grow into. Rather, ...

Phys.org / Scientists may have discovered a new extinct form of life
Prototaxites are something of a prehistoric mystery. They were the first giant organisms on land, towering over ancient landscapes at heights of up to 8 meters. They had smooth trunk-like pillars and no branches, leaves or ...
Tech Xplore / Climate-tailored housing designs cut energy use across Japan's diverse regions
From subarctic to subtropical, Japan's varied climates present a challenge for energy-saving housing design. Adding the projected effects of climate change, with temperatures estimated to rise from 1.5 to 3.5°C by the close ...
Phys.org / Physicists eye emerging technology for solar cells in outer space
Solar cells face significant challenges when deployed in outer space, where extremes in the environment decrease the efficiency and longevity they enjoy back on Earth. University of Toledo physicists are taking on these challenges ...
Medical Xpress / Racism packs a punch for those enduring it over a lifetime
Black Americans die younger than their White counterparts, with an estimated 1.63 million "excess" deaths having occurred between 1999 and 2020. These excess deaths are predominantly attributable to chronic conditions like ...
