Tech Xplore / Batteries from rust? Carbon spheres filled with iron oxide deliver high storage capacity
Conventional lithium-ion batteries contain problematic substances such as nickel and cobalt, and the solvents used to coat the electrode materials are also toxic. Materials scientists at Saarland University are therefore ...
Phys.org / Geologists may have solved mystery of Green River's 'uphill' route
New research may have solved an American mystery which has baffled geologists for a century and a half: How did a river carve a path through a mountain in one of the country's most iconic landscapes? Scientists have long ...
Phys.org / Climate 'fingerprints' mark human activity from the top of the atmosphere to the bottom of the ocean
The world is warming. This fact is most often discussed for Earth's surface, where we live. But the climate is also changing from the top of the atmosphere to the bottom of the ocean. And there is a clear fingerprint of humanity's ...
Medical Xpress / Comparable effectiveness seen for multiartery bypass grafting methods
For lower-risk patients undergoing coronary artery bypass grafting (CABG) for multivessel disease, radial artery plus one internal thoracic artery (SITA+RA) and bilateral ITA (BITA) utilization is increasing, with survival ...
Phys.org / Passerine birds' survival tactic overturns long-held assumptions
Passerine (perching) birds make up 60% of all bird species, including some familiar Australian favorites, like the superb fairy-wren and willie wagtail. Until now, they were believed to only be capable of shallow reductions ...
Phys.org / Skua deaths mark first wildlife die-off due to avian flu on Antarctica
More than 50 skuas in Antarctica died from the high pathogenicity avian influenza virus H5N1 in the summers of 2023 and 2024, marking the first documented die-off of wildlife from the virus on the continent. That is confirmed ...
Tech Xplore / Organic molecule stores renewable energy with record stability, paving the way for better flow batteries
What if the energy produced by wind turbines on a beautiful summer day could be stored until January to heat homes in the dead of winter? It might be possible, thanks to the discovery of a new organic molecule that can hold ...
Phys.org / Listening to polymers collapse: 'Water bridges' pull the strings
It is not easy to follow the interactions of large molecules with water in real time. But this can be easier to hear than to see. This is how an international team deciphered the role of water in the collapse of PNIPAM.
Tech Xplore / In the Australian outback, we're listening for nuclear tests—and what we hear matters more than ever
Tires stick to hot asphalt as I drive the Stuart Highway from Alice Springs northward, leaving the MacDonnell Ranges behind. My destination is the Warramunga facility, about 500 kilometers north—a remote monitoring station ...
Phys.org / A smarter way to watch biology at work: Microfluidic droplet injector drastically cuts sample consumption
Watching proteins move as they drive the chemical reactions that sustain life is one of the grand challenges of modern biology. In recent years, X-ray free-electron lasers, or XFELs, have begun to meet that challenge, capturing ...
Phys.org / Philadelphia communities help AI machine learning get better at spotting gentrification
Over the last several decades, urban planners and municipalities have sought to identify and better manage the socioeconomic dynamics associated with rapid development in established neighborhoods. The term "gentrification" ...
Phys.org / CRISPR screen maps 250 genes essential for human muscle fiber formation
Muscles make up nearly 40% of the human body and power every move we make, from a child's first steps to recovery after injury. For some, however, muscle development goes awry, leading to weakness, delayed motor milestones ...
