Physicists at ETH Zurich have developed an ultra-thin lens capable of converting infrared light into visible wavelengths. This breakthrough, achieved using lithium niobate metasurfaces, could revolutionize imaging technology by enabling compact, high-performance optical devices. How Metalenses Work Traditional lenses rely on curved glass to bend light toward a focal point, but metalenses use nanoscale structures ...
An HIV diagnosis was thought of as a death sentence for decades. Millions of people living with the virus lead long, healthy lives today thanks to revolutionary medical advances. One still unresolved issue is whether HIV/AIDS can ever be totally cured. The response is more hopeful and complicated than you would think. Although ART can ...
The first time NASA’s Parker Solar Probe has observed a big magnetic burst in the sun’s corona, this event could fundamentally alter our understanding of solar storms and their impact on Earth. Against expectations, the spacecraft “touches” the sun’s atmosphere in daring close passes and finds a great surge of energy flinging high-speed plasma towards ...
Physicists at MIT have observed a new form of magnesium that could pave the way for faster, more efficient spintronic memory devices. This breakthrough, termed p-wave magnetism, combines properties of both ferromagnetism and antiferromagnetism, offering a novel approach to data storage and electronic applications. Understanding P-Wave Magnetism Traditional ferromagnets, like fridge magnets, exhibit uniform spin ...
When the most influential tech billionaire in the world and the U.S. president square off in a high-stakes game of political brinkmanship, what results? The response appears to compromise America’s supremacy in space. An explosive conflict between Elon Musk and President Donald Trump over a tax bill descended into threats last week that might compromise ...
Mathematicians all around have struggled with a theory so opaque for more than ten years that it was labeled the “alien’s language.” Developed by Japanese mathematician Shinichi Mochizuki, the Inter-universal Teichmüller Theory (IUT) runs over 2,000 pages and promises to solve the famous ABC conjecture a problem in number theory with great consequences for cryptography, ...
As science shows your cat knows exactly who you are by the scent of your armpits, ears, and even your toes, your cat may show indifference when you walk through the door. Using their strong sense of smell to identify familiar people, a ground-breaking study from Tokyo University of Agriculture has found that domestic cats ...
A groundbreaking discovery has revealed the oldest physical evidence of butterflies and moths, dating back 236 million years to the Triassic period. Researchers uncovered microscopic scales from lepidopterans in fossilized dung samples, filling a 40-million-year gap in the evolutionary record of these insects. The Discovery in Argentina Paleontologists from Argentina and the UK analyzed dung ...
While the Grand Canyon’s 1.7-billion-year-old rock layers and 6-million-year-old chasm have long dominated America’s geological imagination, a far deeper and dramatically younger gorge has been hiding in plain sight. Hells Canyon, slicing 2,400 meters (7,900 feet) into the Idaho-Oregon border, is North America’s deepest river gorge, yet a groundbreaking study reveals it was carved in ...
New research has revealed that the decline of kelp forests in the Gulf of Maine is reshaping marine food webs and energy dynamics. Scientists found that predator-prey interactions and nutrient flow differ significantly between kelp-dominated and turf-algae-dominated reefs, highlighting the ecological consequences of habitat loss. The Decline of Kelp Forests in the Gulf of Maine ...
