Medical Xpress / Surprising culprit leads to chronic rejection of transplanted lungs and hearts
Despite advances in the field of organ transplantation, long-term organ rejection that can become apparent a decade or more after a heart or lung transplant remains a common problem for patients. This chronic organ failure ...
Phys.org / Color-changing nanopigment sensor tracks pH one to ten with stable, repeatable readings
Chemists in South Korea have created a stable color-changing sensor that displays an easily quantifiable response to the pH of its surroundings. Published in Microsystems & Nanoengineering, Dong-Hwan Kim and colleagues at ...
Phys.org / Land plants began reshaping Earth 455 million years ago, scientists discover
Pinpointing when early land plants colonized terrestrial environments and began influencing Earth's systems is a core question in the evolution of the Earth system. A research team led by Prof. Zhao Mingyu at the Institute ...
Phys.org / The Mojave Desert is a hot spot for off-roading: Why a judge shut down more than 2,200 miles of trails
The desert tortoise, a once-resilient reptile, is a keystone species in the Mojave Desert, where other animals depend for their survival on the burrows it digs. But it is imperiled in California thanks in part to an unusual ...
Phys.org / The physics of sneaker squeaks: High-speed imaging shows how they arise from supersonic detachment pulses
Basketball shoes on a gym floor, bicycle brakes in need of a tune-up, or the squeal of tires are everyday examples of squeaking sounds. Such sounds have long been attributed to stick-slip friction, or a cycle of intermittent ...
Phys.org / New michelin star jellyfish discovered in Japanese aquaria
Researchers have reported the discovery of a new species of jellyfish, Malagazzia michelin, marking only the second species of its genus ever found in Japanese waters. Led by Takato Izumi of Fukuyama University, the discovery ...
Tech Xplore / AI analysis finds sunnier sites and compact layouts cut solar's land footprint
As solar energy is rapidly becoming the world's largest renewable power source, new research from McGill University offers a clearer picture of how much land that growth could require and how smarter choices could mitigate ...
Tech Xplore / How AI could help make society less selfish
The Care Bears taught a generation of kids that sharing is caring, but not everyone has carried this principle into adulthood. Researchers at Michigan State University have found a new angle to promote cooperation: artificial ...
Phys.org / Scientists discover 10 new species of Hawaiian moths
University of Hawaiʻi at Mānoa researchers identified 10 new species and seven new groups (genera) of Hawaiian leaf-roller moths. While new species are frequently discovered, the description of a new genus of insects is ...
Phys.org / Ion bombardment triggers a reliable quantum switch in tantalum disulfide crystals
When you toss a coin, you put it into a higher-energy state until it falls back down again. It can then end up in one of two possible states: heads or tails. No matter which state the coin was in before, after the toss both ...
Phys.org / An endangered natural pharmacy hidden in coral: Hundreds of reef-dwelling microbes reveal untapped potential
Coral reefs are teeming with life: they are home to over a third of all marine animal and plant species on Earth, despite covering less than one percent of the ocean floor. However, this immense diversity is under threat ...
Phys.org / Scientists develop vitamin A-enriched tomato to fight global deficiency
University of Florida scientists have developed a tomato packed with significantly higher levels of vitamin A, a breakthrough that could help combat one of the world's most widespread nutritional deficiencies. In research ...
