Tech Xplore / Using light to distinguish real from fake with hard-to-replicate 'artificial fingerprints'
Shine a light, and the real can be distinguished from the fake. KAIST researchers have developed a security technology that uses unique artificial fingerprints created by the random assembly of nanoparticles. Although extremely ...
Phys.org / How rising air plumes help spike moist heat
As climate change has led to more frequent extreme-heat events around the world, moist heat metrics such as wet-bulb temperature, which combines temperature and humidity, have become increasingly relevant. Days with both ...
Tech Xplore / AI prevents unstable material designs, cutting costs for chip and cooling applications
Today, anyone with a large enough artificial intelligence model can generate millions of new material designs in minutes. Unfortunately, that hasn't led to a huge leap in the number of new materials being used to improve ...
Medical Xpress / Neural implant in Korea remotely controlled from the United States
A researcher in Chicago remotely controls a miniaturized brain implant in Daejeon, Korea—over the internet. Korean researchers have developed a wireless device that can deliver drugs and light to precisely modulate targeted ...
Phys.org / Chemical physicists quantitatively model electron interactions in real quantum materials
A team of scientists from Caltech and Yale University has shown for the first time how to accurately quantify an important quantum phenomenon in metals, called the Kondo effect, for specific real materials. Unlike previous ...
Tech Xplore / Tri-layer electrolyte improves safety and lifespan of lithium-metal batteries
Lithium metal batteries (LMBs) that use pure lithium (Li) for their negative electrodes are attracting significant attention because of their extremely high theoretical capacity. However, their practical applications are ...
Tech Xplore / Amoeba-inspired method could enable energy-efficient hardware for complex optimization
Combinatorial optimization problems are ubiquitous, underpinning decision-making in a wide range of fields, including logistics, transportation, communication networks, drug discovery and materials science. However, these ...
Phys.org / NASA Johnson pilots chase moon's shadow for eclipse science
During the Aug. 12 total solar eclipse over Europe, scientists aimed to study a long-standing mystery: why the sun's outer atmosphere, the corona, is far hotter than its visible surface. Capturing the data they needed meant ...
Tech Xplore / New system recognizes masked faces using eyes and forehead
A face-recognition system that can identify people even if they are wearing a face mask covering their nose and mouth is discussed in the International Journal of Computational Vision and Robotics. The new system uses biometrics ...
Medical Xpress / Fever-like body heat reduces cognitive differences in preclinical autism model
Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by differences in communication, social interactions, learning and sensory processing. Past studies have found that when some autistic children ...
Phys.org / New clues about how space travel may affect women's health
As space missions become longer and ambitions for deep-space travel grow, scientists are working to understand how life beyond Earth may affect every system in the human body. Two years after her initial study took flight, ...
Phys.org / How a glacier collapse may have caused Nepal-Tibet disaster
A huge piece of ice that fell thousands of meters from a glacier into a river below may have unleashed the disaster in Nepal and Tibet that killed at least 180 people.
