Phys.org / Dissolvable hydrogel could enable personalized bone implants
Bones broken in a skiing accident usually heal on their own. But if the break is too severe or a bone tumor needs to be removed, surgeons insert an implant that enables the bone to grow back together. Implants often consist ...
Phys.org / 'Old Mother Goose' challenges a 14-million-year lineage story in New Zealand
The discovery of a rare fossil goose in an ancient Central Otago lake shows the evolutionary history of Aotearoa New Zealand birds is much more dynamic than once thought, a University of Otago–Ōtākou Whakaihu Waka researcher ...
Phys.org / Are these killer whales cannibals? They probably don't think so themselves
In 2022, a Russian whale researcher made a remarkable discovery on Bering Island off Russia's Pacific coast: a severed killer whale fin marked with the teeth of another killer whale. In 2024, it happened again. The two finds ...
Phys.org / Modern twist on wildfire management methods has a bonus feature that protects water supplies
Wildfires are among the most economically costly natural disasters and are becoming more severe and frequent due to global warming. The United Nations Office for Disaster Risk Reduction estimates that global damage from wildfires ...
Phys.org / Planting big native trees early can simplify forest restoration in Aotearoa
Native forest restoration usually starts with faster growing "nurse plants" that provide shelter under which to plant bigger trees—but new research suggests some big canopy trees can be planted early too. Scientists monitored ...
Phys.org / MeerKAT discovers record-breaking cosmic laser halfway across the universe
Astronomers using the MeerKAT radio telescope in South Africa have discovered the most distant hydroxyl megamaser ever detected. It is located in a violently merging galaxy more than 8 billion light-years away, opening a ...
Phys.org / Agrivoltaics can increase or reduce yields and profits, depending on the crop and where the systems are deployed
In a world where increasing demands for food security and energy strain existing resources, scientists are looking for new ways to maximize both. One potential option, agrivoltaics, integrates solar photovoltaics with crops. ...
Phys.org / Rydberg atoms detect clear signals from a handheld radio
For the first time, a team of US researchers has used sensors containing highly excited Rydberg atoms to detect signals from an ordinary handheld radio. Through a careful approach to demodulating the incoming signals, Noah ...
Phys.org / Ultrasound-activated 'nanoagents' kill superbugs hiding in biofilms
Scientists have designed nanoagents that act like smart drug-delivery capsules—carrying an antibiotic deep into bacterial infection sites and releasing it only when activated by gentle ultrasound. Delivering antibiotics ...
Tech Xplore / A 270-year-old physics trick could supercharge affordable battery technology
Roughly 270 years ago, Dr. Johann Gottlob Leidenfrost from Germany observed a peculiar behavior of water droplets on heated metal surfaces. In his manuscript, "A Tract About Some Qualities of Common Water," he described how ...
Phys.org / Northern hemisphere snow cover is shrinking—new analysis tracks how fast
Faculty at Mississippi State University are continuing work at the intersection of mathematics, statistics, and climate science with the publication of a new study examining regional snow cover trends across the Northern ...
Phys.org / What happens if truth is lost? Philosopher explains how truth defines our humanity
Behind every breakthrough, there is a quest for truth. This desire is wired into humans—an insatiable curiosity about the world. Questions about truth have perplexed philosophers for thousands of years, but many focus on ...
