Aerobic respiration began hundreds of millions of years earlier than previously thought, study suggests
Oxygen is a vital and constant presence on Earth today. But that hasn't always been the case. It wasn't until around 2.3 billion years ago that oxygen became a...
New 3D method maps Paleolithic engravings at submillimeter resolution
A team of archaeologists from the Universitat Jaume I, the University of Barcelona, and the Catalan Institution for Research and Advanced Studies (ICREA) has de...
Compound in 500-million-year-old fossils sheds new light on Earth's carbon cycle
A UT San Antonio-led international research team has identified chitin, the primary organic component of modern crab shells and insect exoskeletons, in trilobit...
The surprising power of a tiny, disordered protein in a mitochondrial supercomplex
For decades, scientists assumed that order drives efficiency. Yet in the bustling machinery of mitochondria—the organelles that crank out adenosine triphosphate...
Self-assembling 'bundlemers' could reshape next-generation protein-based materials
Proteins are the building blocks of life. These biomolecules comprise chains of amino acids that fold into precise shapes to perform specific jobs in nature. Bu...
Artificial light is reshaping caracal behavior, limiting where the South African wild cat can hunt
Artificial light is one of the most ingrained features of modern life. For humans, light after dark offers convenience and a sense of safety. For wildlife, it's...
Norway's Sami population posed an enigma for the occupying Nazis, researcher says
Historian and Ph.D. research fellow Andreas Eliassen Grini at the Norwegian University of Science and Technology (NTNU) has delved into German soldiers' descrip...
Extreme plasma acceleration in monster shocks offers new explanation for fast radio bursts
In a new study published in Physical Review Letters, scientists have performed the first global simulations of monster shocks—some of the strongest shocks in th...
Could ionospheric disturbances influence earthquakes?
Researchers at Kyoto University have proposed a new physical model that explores how disturbances in the ionosphere may exert electrostatic forces within Earth'...
Revealing deformation mechanisms of the mineral antigorite in subduction zones
Earth's surface is covered by more than a dozen tectonic plates, and in subduction zones around the world—including the Japanese Islands—plates converge and den...
Almost half of the world's aquatic environments are severely contaminated by waste, research reveals
"Dirty" or "extremely dirty": these are the classifications of 46% of the world's aquatic environments. This conclusion comes from a study that compiled and sys...
When silicon fills the role of carbon: Debut of all-silicon cyclopentadienides
Carbon's unique chemical properties allow it to be an essential building block for life on Earth and many other molecules we rely on for day-to-day life—but wha...
