Phys.org / Explosive evaporation unlocks new possibilities in 3D printing and chemical analysis
Water droplets might seem simple at first. But when nearing evaporation, a desperate power struggle of competing physical forces can emerge, with explosive effects. In a Proceedings of the National Academy of Sciences publication, ...
Phys.org / AI tackles one of math's most brutal problems: Inverse PDEs
Penn Engineers have developed a new way to use AI to solve inverse partial differential equations (PDEs), a particularly challenging class of mathematical problems with broad implications for understanding the natural world.
Phys.org / Long-term study of COVID lockdown and family life shows unexpected, lasting effects on fatherhood
In the years following the COVID-19 pandemic, much has been said about how the lockdowns created conditions for dual-parent families to spend more time at home with their children. In an ideal vision of family life, this ...
Phys.org / A better way to search for extraterrestrial intelligence
When you're looking for signs of extraterrestrial intelligence, it helps to know what you're looking for and to go about it in the most efficient way. But work so far has generally not done so, writes Benjamin Zuckerman, ...
Phys.org / DESI-HVS1 is an old hypervelocity star ejected from the galactic center, observations suggest
Chinese astronomers report the discovery of DESI-HVS1, which may be an old metal-poor hypervelocity star of galactic center origin. The finding, based on the data from the Dark Energy Spectroscopic Instrument (DESI) and ESA's ...
Phys.org / Dinosaurs may have originated 10 million years earlier than fossils show
Dinosaurs are among the most majestic and iconic animals to have ever walked on our planet. While they are now extinct, they are estimated to have inhabited Earth for over 165 million years.
Phys.org / When the Schuylkill swallowed the city: Lessons from Hurricane Ida's historic flood
New Penn research shows that Hurricane Ida wasn't a once-in-a-century anomaly but a preview of how climate change, urbanization, and aging infrastructure are rewriting flood risk.
Phys.org / After flames strip hillsides bare, the next storm can unleash something far more destructive downstream
Wildfires can increase flooding risks in and downstream of burned areas by removing vegetation and disturbing hydrologic processes. As the climate changes, the severity of both wildfires and heavy rainfall events is increasing, ...
Phys.org / Physicists achieve first-ever 'quadsqueezing' quantum interaction
Researchers at the University of Oxford have demonstrated a new type of quantum interaction using a single trapped ion. By creating and controlling increasingly complex forms of "squeezing" – including a fourth-order effect ...
Phys.org / Physicists have measured 'negative time' in the lab
As Homer tells us, Odysseus made an epic journey, against the odds, from Troy to his home in Ithaca. He visited many lands, but mostly dwelt with the nymph Calypso on her island. We can imagine that his wife, Penelope, would ...
Phys.org / Under crushing hypergravity, fruit flies adapt—and recover
Expose an animal to extreme physical stress, and the expectation is simple: It will break down. But when UC Riverside scientists subjected fruit flies to forces many times stronger than Earth's gravity—a condition called ...
Phys.org / How oak trees outwit their predators
Spring in the forest: Many insects, particularly caterpillars, hatch just when the trees' nutrient-rich leaves are still young and soft. This means they find a table laden with food and can start eating straight away. If ...
