Phys.org / Emperor penguin colonies reveal decades-long resilience and flexible breeding sites
With their charming waddles, heat-conserving huddles and tuxedo-like plumage, emperor penguins are among the world's most recognizable animals. Recent satellite surveys estimate that hundreds of thousands of the flightless ...
Tech Xplore / Bifur-circuits let shape-changing devices keep electrical connections intact
A new set of modular components allows users to create reconfigurable smart devices with electrical connections that keep working no matter what shape the structure forms.
Phys.org / How the sun's galactic journey and superflare-filled youth shaped Earth's climate
At the center of our solar system, the sun influences every planet that orbits it. In two recent studies, scientists uncovered how ancient events in the sun's history may have helped create Earth's unique climate and driven ...
Phys.org / Observing the vibrations of neighboring atoms with an atomic-scale double slit
Efficiently controlling heat generation has become a major challenge as the semiconductors used in smartphones, computers and similar devices have become higher-performing and more miniaturized. The way heat is transmitted ...
Phys.org / Wear it Purple Day is about more than a T‑shirt
Today is Wear it Purple Day—when students and staff at high schools and universities are invited to wear purple clothing to recognize and celebrate gender- and sexuality-diverse (GSD) young people. Workplaces are also encouraged ...
Phys.org / Some Galápagos 'yellow' sea turtles remain homebodies, surprising scientists
Sea turtles are famous for being prodigious wanderers. Guided by Earth's magnetic field, ocean currents and the sun, they tend to crisscross the seas in search of food, returning to the region of their birth every few years ...
Phys.org / Species discoveries reveal emerging biodiversity hotspots worldwide
We share our planet with millions of plants and animals. This variety of life is known as biodiversity, a term encompassing everything from microscopic genes to entire ecosystems, such as deserts and vibrant coral reefs.
Phys.org / 'Damaging the Antarctic damages us all'—scientists warn of the potential impacts of coastal freshening
Many of Antarctica's smallest inhabitants have evolved over millions of years so that their body fluids are similar in chemical composition to those of seawater. However, a combination of melting glaciers, increased rain ...
Phys.org / Cellular 'glue' helps epithelial tissues engulf dead cells while staying sealed
A protein that sticks cells and tissues together has been found to have a surprising second job: helping cells that are packed into a continuous sealed layer, also known as epithelial cells, engulf nearby dead cells.
Phys.org / Reworked tRNAs enable protein design with up to 34 amino acids
Scientists have been hard at work for more than 20 years to instruct biological systems, such as E. coli cells, to produce proteins they don't naturally produce. Success could mean faster, cheaper, more innovative solutions ...
Phys.org / Starting upstream: Rethinking how public health supports young people
When GCH assistant professor Rochelle Davidson Mhonde began working with adolescent survivors of sexual violence, she saw the ripple effects of their trauma: depression, anxiety, substance use and other health challenges. ...
Phys.org / When the dust settles: Field experiments measure how everyday activity resuspends hazardous particles
Being prepared for an emergency is key to keeping people safe. This means more than just having supplies such as food, water and first-aid kits. Sometimes, the most important preparation is having the right data to help first ...
