Phys.org / Galaxy-group motion suggests slower expansion in our cosmic neighborhood
Two new studies have measured the expansion of the universe in our immediate cosmic neighborhood using a novel method that analyzes the motion of two nearby galaxy groups within their surrounding cosmic flow. The results ...
Phys.org / Queen bees survive winter flooding by breathing underwater
Hibernation is a risky endeavor for many animals, as they can be taken away by the elements or predators. For several months of the year, queen bumblebees enter a dormant state underground called diapause. While this keeps ...
Phys.org / Corpses leave clues behind in the soil long after they're gone
It is not uncommon for a body to be moved after a murder, usually to hide or eliminate evidence. And while the Arizona desert may seem like the perfect place to commit such a crime, a new study shows that a cadaver can still ...
Phys.org / Highlighting the hidden climate cost of the Israel–Gaza war
A new study estimates that the Israel–Gaza war has generated around 33 million metric tons of carbon dioxide equivalent (CO2e), highlighting the often-overlooked environmental impact of armed conflict.
Phys.org / Howler monkey ancestors began eating leaves 13 million years ago, changing course of primate history in South America
Thirteen million years ago, a group of medium-sized monkeys known for guarding their territory among the treetops with fearsome "howls" started doing something new. These monkeys, among the oldest known ancestors of the modern ...
Phys.org / Fiber setup compresses mid-infrared pulses to 187 femtoseconds using just 80 watts
Ultrashort mid-infrared (mid-IR) laser pulses are essential for applications such as molecular spectroscopy, nonlinear microscopy, and biomedical imaging, but their generation often relies on complex and power-intensive systems ...
Phys.org / Study finds nanocube cation exchange can begin on one face, not six
In a paper published today in Nature Synthesis, a team from the lab of University of Chicago Pritzker School of Molecular Engineering (UChicago PME) and Chemistry Department Prof. Paul Alivisatos explores the role of cation ...
Phys.org / Hydrogen atmosphere could keep exomoons habitable for billions of years
Liquid water is considered essential for life. Surprisingly, however, stable conditions that are conducive to life could exist far from any sun. A research team from the Excellence Cluster ORIGINS at LMU and the Max Planck ...
Phys.org / Flash heating upcycles waste glass into SiC nanowires in seconds
Engineering silicon carbide (SiC) with tailored morphologies for electronics and structural reinforcement materials has always been a costly and time-consuming affair, but scientists can now do it in a flash. A new study ...
Phys.org / Fish study shows that sexual harassment behavior might matter for ecosystems
For decades, ecologists have known that how a species looks or eats affects its environment. But a new study by researchers at the University of California, Santa Cruz, shows that social behavior related to mating can be ...
Phys.org / Florida's most at-risk bat moves into safer artificial roosts
Finding bats in the attic or under roof tiles is no homeowner's idea of fun. But Florida's endangered bonneted bats have few natural options left. With a dwindling number of large, old trees with cavities—their preferred ...
Phys.org / Stacked quantum materials enable precise spin control without external magnetic fields
Spintronics—a technology that harnesses the electron's magnetic quantum states to carry information—could pave the way for a new generation of ultra-energy-efficient electronics. Yet a major challenge has been the ability ...
