Phys.org / When trade routes shift, so do clouds: Researchers uncover ripple effects of new global shipping regulations
When militia attacks disrupted shipping lanes in the Red Sea, few imagined the ripple effects would reach the clouds over the South Atlantic. But for Florida State University atmospheric scientist Michael Diamond, the rerouting ...
Phys.org / Lab-grown diamond coatings shown to prevent mineral scale in industrial pipes
In industrial pipes, mineral deposits build up the way limescale collects inside a kettle ⎯ only on a far larger and more expensive scale. Mineral scaling is a major issue in water and energy systems, where it slows flow, ...
Medical Xpress / Not all immune cells are created equal: Memory T cells in tissues outlast those in blood
Memory T cells are a special type of white blood cell that "remember" past infections and vaccines, helping our bodies to quickly respond if we encounter the same germs again. These cells are found throughout the body: some ...
Phys.org / Metasurfaces etched into 2D crystals boost nonlinear optical effects at nanoscale
In January, a team led by Jim Schuck, professor of mechanical engineering at Columbia Engineering, developed a method for creating entangled photon pairs, a critical component of emerging quantum technologies, using a crystalline ...
Dialog / Hydrogenases spill the beans: Key catalytic moves revealed
Hydrogenases catalyze the reversible splitting and production of hydrogen gas (H2), using complex catalytic cofactors comprising Earth-abundant nickel and/or iron ions. These enzymes, especially the [NiFe]-hydrogenases (fig. ...
Phys.org / Info to decipher secret message in Kryptos sculpture at CIA headquarters sells for close to $1M
The information needed to decipher the last remaining unsolved secret message embedded within a sculpture at CIA headquarters in Virginia sold at auction for nearly $1 million, the auction house announced Friday.
Phys.org / Tea leaf experiments suggest tropical forests may better withstand climate change
Researchers at Northern Arizona University and the Smithsonian found an unconventional method to understand how rainforests will survive with climate change—making tea with living leaves at the top of the rainforest canopy.
Medical Xpress / Cerebrospinal fluid motion in the brain captured in remarkable detail
Cerebrospinal fluid (CSF) is a clear and watery liquid that flows in and around the brain and spinal cord. Its functions include protecting parts of the nervous system, delivering nutrients and removing metabolic waste.
Phys.org / Bright squeezed vacuum reveals hidden quantum effects in strong-field physics
In a new study published in Nature Physics, researchers have demonstrated that quantum light, particularly bright squeezed vacuum (BSV), can drive strong-field photoemission at metal needle tips.
Phys.org / Climate change is now warming the deepest parts of the Arctic Ocean
While it is well known that climate change is heating the world's oceans, it was thought that the deep sea was safe from its effects—until now. Researchers have discovered that a rapidly warming part of the Atlantic is ...
Phys.org / Moss spores survive 9 months outside International Space Station
Mosses thrive in the most extreme environments on Earth, from the peaks of the Himalayas to the sands of Death Valley, the Antarctic tundra to the lava fields of active volcanoes. Inspired by moss's resilience, researchers ...
Tech Xplore / Colorado is pumping the brakes on first-of-its-kind AI regulation to find a practical path forward
When the Colorado Artificial Intelligence Act passed in May 2024, it made national headlines. The law was the first of its kind in the U.S. It was a comprehensive attempt to govern "high-risk" artificial intelligence systems ...
