Phys.org / Watching a critical green-energy catalyst dissolve, atom by atom
Iridium oxide is one of the most important—and most problematic—materials in the global push toward clean energy. It is currently the most reliable catalyst used in the conversion of energy to chemicals by electrolysis, ...
Phys.org / Scientists discover 'levitating' time crystals that you can hold in your hand
Time crystals, a collection of particles that "tick"—or move back and forth in repeating cycles—were first theorized and then discovered about a decade ago. While scientists have yet to create commercial or industrial ...
Medical Xpress / ABCA1 protein releases molecular brakes on solid tumor immunotherapy, study finds
In recent years, cancer researchers have made major breakthroughs by using the body's immune system to fight cancer. One of the most promising approaches, known as immune checkpoint blockade, works by releasing molecular ...
Phys.org / Self-assembling 'bundlemers' could reshape next-generation protein-based materials
Proteins are the building blocks of life. These biomolecules comprise chains of amino acids that fold into precise shapes to perform specific jobs in nature. But these elegant structures form only under narrow pH and temperature ...
Tech Xplore / Interface engineering lifts perovskite solar cell performance to 26.19% efficiency
Researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences, in collaboration with international partners, have engineered a thin two-dimensional perovskite phase ...
Phys.org / When silicon fills the role of carbon: Debut of all-silicon cyclopentadienides
Carbon's unique chemical properties allow it to be an essential building block for life on Earth and many other molecules we rely on for day-to-day life—but what about carbon's neighbor? Silicon is located one row below ...
Medical Xpress / Maternal perinatal depression may increase the risk of autistic-related traits in girls
A research team from the Department of Psychiatry at Tohoku University, led by Dr. Zhiqian Yu and Professor Hiroaki Tomita, has uncovered compelling evidence that maternal perinatal depression—psychological distress occurring ...
Medical Xpress / The body processes good fats and bad fats differently, study finds
The concept of "good fats" and "bad fats" has influenced diet trends, public health policy, and biomedical research for decades. Now, a new study led by Thomas A. Vallim, Ph.D., a researcher and professor of medicine in the ...
Medical Xpress / Two key enzymes drive fat loss while preserving muscle: New pathway may lead to safer obesity treatments
A team of scientists has uncovered a critical mechanism that could pave the way for safer and more effective obesity treatments. The findings, published in Nature Communications, shed light on how leptin, a hormone that regulates ...
Phys.org / Three-component catalyst boosts ammonia from nitrate electrolysis by more than 50%
A research team led by Dr. Dandan Gao from the Department of Chemistry at Johannes Gutenberg University Mainz (JGU) has developed a new method for the sustainable production of ammonia and formic acid. Ammonia is indispensable ...
Phys.org / Simulation finds Grass2Gas biogas systems may reduce dairy emissions by over 20%
Implementing novel management practices in dairy farming, one of the commonwealth's major agricultural industries, could help alleviate a large source of both nutrient pollution and greenhouse gas emissions, according to ...
Phys.org / Polarstern heads to the Weddell Sea to probe Antarctica's sharp sea ice drop
With the departure of the research vessel Polarstern from Punta Arenas (Chile) scheduled for this weekend, the "Summer Weddell Sea Outflow Study" (SWOS) international expedition will commence. Up to early April, a multidisciplinary ...
