A complex process can modify non-magnetic oxide materials in such a way to make them magnetic. The basis for this new phenomenon is controlled layer-by-layer growth of each material. An international research team with researchers from Martin Luther University Halle-Wittenberg (MLU) reported on their unexpected findings in the journal Nature Communications.
After above-knee amputation, there is the option of a prosthesis that is placed directly in the thigh bone (osseointegration). Despite the fact that bone-anchored prostheses have been used for thirty years, researchers at the Radboud University Medical Center have now published the first long-term evaluation of such a prosthesis. It turns out that the procedure is not without stoma problems, but that these can usually be treated with simple measures and that the osseointegration implant system leads to a permanent improvement in mobility and quality of life.
Researchers at Karlsruhe Institute of Technology (KIT) and Jilin University in Changchun/China investigated a highly promising anode material for future high-performance batteries - lithium lanthanum titanate with a perovskite crystal structure (LLTO). As the team reported in the Nature Communications journal, LLTO can improve the energy density, power density, charging rate, safety, and cycle life of batteries without requiring a decrease of the particle size from micro to nano scale.

Rapid first aid during cardiac arrest makes the difference between life and death. But what happens to the heart and the internal organs when people come running and begin to give well-meaning but heavy-handed heart massage as they attempt to keep the person who has suffered a cardiac arrest alive?
A research collaboration between the Department of Forensic Medicine at Aarhus University, Denmark, and the East Midlands Forensic Pathology Unit at the University of Leicester in the UK now offers an answer to this question.
Used tyres pose a serious environmental risk owing to the damage that may be caused when they are stored in the environment. They are emerging in ever greater numbers from one year to the next in developed countries so revalorizing them is a subject that is attracting great interest and is being spurred on by the increasingly stringent regulations in terms of their management.
A team of geoscience researchers in the Virginia Tech College of Science has developed a new theory to explain how and why injection-induced earthquakes continue to occur even when injection rates decline.
Experts have known since the 1960s that when oilfield wastewater is pumped into the ground with deep injection wells, earthquakes can occur. Over the past decade, injection-induced earthquakes have become regular occurrences throughout oil and gas basins worldwide, particularly in the central United States, and potentially in China and Canada, as well.
Mobile phones have the power to change the lives of women living in remote communities by reducing barriers to information and increasing access to local economies. However, the introduction of new technologies can hamper efforts to empower women by increasing disparities in power dynamics.

The past few months have been a highly unusual time as people sheltered in place to prevent the spread of COVID-19. Schools, streets and stadiums fell silent, tourist hot spots became ghost towns, and sidewalk traffic largely consisted of grocery and food deliveries.
New Orleans, LA -- Research led by Nicolas Bazan, MD, PhD, Boyd Professor and Director of the Neuroscience Center of Excellence at LSU Health New Orleans School of Medicine, and Ludmila Belayev, MD, LSU Health New Orleans Professor of Neuroscience, Neurology and Neurosurgery, has unlocked a key fundamental mechanism in the communication between brain cells when confronted with stroke. They report that DHA not only protected neuronal cells and promoted their survival, but also helped maintain their integrity and stability.
How a valveless embryonic heart tube pumps blood is a long-standing scientific mystery. Thanks to innovations in light-based technology, fresh insights are now available into the biomechanics of mammalian cardiogenesis—and in particular, the pumping dynamics of the mammalian tubular embryonic heart.

ORLANDO, August 6, 2020 - University of Central Florida researchers have developed a new type of laser beam that doesn't follow long-held principles about how light refracts and travels.
The findings, which were published recently in Nature Photonics, could have huge implications for optical communication and laser technologies.
"This new class of laser beams has unique properties that are not shared by common laser beams," says Ayman Abouraddy, a professor in UCF's College of Optics and Photonics and the study's principal investigator.
As more states in the U.S. push for increased reliance on variable renewable energy in the form of wind or solar power, long-term energy storage may play an important role in assuring reliability and reducing electricity costs, according to a new paper published by Caltech researchers.
The barrier islands of North Carolina's Cape Hatteras National Seashore are among the most popular recreational destinations on the Atlantic coast. Park managers strive to integrate the needs of wildlife with recreational use of the area's beaches, but in some cases, they impose restrictions on the latter in order to preserve the former--sometimes even completely closing portions of beaches to pedestrian and off-road vehicle traffic to protect nesting birds.
