Astronomers have long known the universe is expanding--but exactly how fast remains one of the biggest mysteries in cosmology. Different techniques for measuring the Hubble constant stubbornly disagree, creating the so-called "Hubble tension." Now .. ...

Jupiter's icy moons may have been seeded with the chemical ingredients for life from the very beginning. An international team of scientists modeled how complex organic molecules--essential building blocks for biology--could have formed in the ...

Scientists racing to tackle plastic pollution have created a surprising new contender: a biodegradable packaging film made partly from milk protein. Researchers at Flinders University blended calcium caseinate with starch and natural nanoclay to form ...

Astronomers have spotted what may be one of the universe's earliest barred spiral galaxies -- a striking cosmic structure forming just 2 billion years after the Big Bang. The galaxy, COSMOS-74706, dates back about 11.5 billion years and contains a .. ...

Saturn's largest moon, Titan, may have been born in a colossal cosmic crash. New research suggests Titan formed when two older moons slammed together hundreds of millions of years ago--an event so violent it reshaped Saturn's entire moon system and . ...

Researchers at Nagoya University have created a more efficient iron-based photocatalyst that could reduce the need for rare and expensive metals in advanced chemistry. Unlike earlier designs, the new catalyst uses far fewer costly chiral ligands ...

Scientists have unveiled a breakthrough way to turn natural gas--long burned as fuel--into valuable chemical building blocks for medicines and other high-demand products. By designing a clever iron-based catalyst powered by LED light, researchers ...

Engineers at UC Davis have built a remarkable device that creates power at night by tapping into something we rarely think about: the vast cold of outer space. Using a special type of Stirling engine, the system links the warmth of the ground to the ...

Green hydrogen could be a game-changer for the clean energy transition--but right now, it's too expensive and still relies on harmful "forever chemicals." A new EU-backed project called SUPREME aims to fix that by reinventing how hydrogen is made. .. ...

Researchers have discovered new ways to shape quantum light, creating high-dimensional states that can carry much more information per photon. Using advanced tools like on-chip photonics and ultrafast light structuring, they're pushing quantum ...
