A light-sensitive crystal is opening the door to a new era of “light-written” technology。 Arsenic trisulfide can be reshaped and permanently altered using simple light, creating ultra-fine optical patterns without expensive manufacturing tools。 Scientists even etched a nanoscale portrait of Einstein and high-density patterns that could act as secur
Researchers at Stanford have developed a compact optical amplifier that dramatically boosts light signals using very little power。 By recycling energy inside a looping resonator, the device achieves strong amplification with minimal noise and wide bandwidth。 Its efficiency and small size mean it could run on batteries and be integrated into consume
Scientists are using sunlight to turn plastic waste into clean fuels like hydrogen, offering a breakthrough solution to both pollution and energy challenges。 While still in development, the approach could transform trash into a valuable resource for a low-carbon future
Scientists have created tiny “optical tornadoes” — swirling beams of light that twist like miniature whirlwinds — using a surprisingly simple setup based on liquid crystals。 Instead of relying on complex nanotechnology, the team used self-organizing structures called torons to trap and manipulate light, causing it to spiral and rotate in intricate
A spectacular cosmic event nicknamed “SN Winny” could help solve one of astronomy’s biggest mysteries: how fast the universe is expanding。 This rare superluminous supernova, located 10 billion light-years away, appears five times in the sky thanks to gravitational lensing, creating a dazzling “cosmic fireworks” effect。 By measuring the slight delay
Scientists have uncovered a surprising link between simple body movement and brain health: every time you tighten your abdominal muscles—even slightly—your brain may gently sway inside your skull。 This subtle motion, triggered by pressure changes in connected blood vessels, appears to help circulate cerebrospinal fluid around the brain, potentially
Astronomers have spotted something surprising in the far outer Solar System—a faint, short-lived atmosphere clinging to a tiny icy world that shouldn’t be able to hold one at all。 The object, called 2002 XV93, is far smaller than Pluto, yet observations during a rare stellar alignment revealed its presence through a subtle dimming of starlight。 Eve
Scientists have uncovered the true boundary of the Milky Way’s star-forming region using stellar “age mapping。” They found a telltale U-shaped pattern showing that star formation drops sharply around 35,000–40,000 light-years from the center。 Beyond that, stars are mostly migrants, slowly drifting outward rather than forming in place
Scientists have uncovered a tiny wall-dwelling spider named Pikelinia floydmuraria, inspired by Pink Floyd。 Despite its size, it’s a fierce predator that hunts ants much larger than itself and helps reduce common urban pests like mosquitoes and flies。 Its clever strategy of building webs near lights makes it especially effective
A scorching, airless world just 48 light-years away is offering scientists a rare glimpse into the geology of distant planets。 Using the James Webb Space Telescope, researchers studied LHS 3844 b—a tidally locked “super-Earth” with a permanent dayside hot enough to melt metal—and discovered it’s a dark, barren rock with no atmosphere
Tyrannosaurs may be famous as fearsome apex predators, but new research reveals a more opportunistic—and slightly grim—side to their behavior。 Using high-resolution 3D scans, a researcher identified precise bite marks on a massive tyrannosaur foot bone, showing that a smaller tyrannosaur had fed on the remains of a much larger relative over 75 mill
A centuries-old vision of a mechanical volcano has finally erupted into reality, as two University of Melbourne engineering students recreated a design first imagined in 1775 by volcanology enthusiast Sir William Hamilton。 Drawing from an 18th-century watercolor and a preserved sketch, they used modern tools like LED lighting and electronic systems
A decades-old cosmic mystery has finally been cracked: the strange X-rays coming from the bright star gamma-Cas are caused by a hidden stellar companion feeding off it。 Using cutting-edge observations from the XRISM space mission, astronomers discovered that an unseen white dwarf star is siphoning material from gamma-Cas, heating it to extreme temp
