Phys.org / Ethiopia's Afar Rift provides glimpse into life and death 100,000 years ago

The study of ancient cultures around Ethiopia during the Middle Stone Age (MSA) time period is important for understanding how some of the first Homo sapiens lived and eventually left Africa. Unfortunately, there are not ...

Phys.org / This nasal spray rewinds the aging brain, restoring memory and reversing inflammation in preclinical models

Picture this: your brain is a high-performance engine. Over decades, it doesn't just wear down, it also starts to run hot. Tiny "fires" of inflammation smolder deep within the brain's memory center, creating a persistent ...

Phys.org / A silicon-compatible path toward scalable quantum systems

Beginning in the 1950s, silicon transformed the electronics industry by enabling smaller and faster devices that could be reliably manufactured at scale. More than six decades later, silicon-based semiconductors remain at ...

Phys.org / Picky methane-consuming microorganisms prefer carbon monoxide, opening the door to more greenhouse gas release

Research by microbiologists Reinier Egas and Cornelia Welte of Radboud University shows that many methane-consuming microorganisms actually prefer carbon monoxide over methane. When carbon monoxide is present, they consume ...

Phys.org / Glaciers may flow into the ocean more quickly than we think

Models of glacial flow and retreat rely on estimates of glacial ice viscosity, the measure of the ice's resistance to flow. Ice viscosity is dependent on the stress applied to the glacier. Most ice sheet models use a standard ...

Phys.org / Some lake bacteria survive by slashing half their genome and never looking back

Researchers at the University of Zurich have analyzed the genome of bacteria living in Lake Zurich to conclude that microbes employ two different strategies to colonize new habitats. Some acquire new traits, as expected—but ...

Phys.org / Andean volcanic eruptions during the Late Miocene likely drove global cooling

Mark Clementz, a professor in the University of Wyoming Department of Geology and Geophysics, and colleagues have produced a compelling study that shows that an increase in volcanic activity in the Andes in the Late Miocene ...

Phys.org / AI-guided electron microscope provides unique glimpse into the world of MXenes

The use of artificial intelligence has enabled researchers at the National Laboratory of the Rockies (NLR) to gain a greater understanding of two-dimensional (2D) materials that can be useful for energy storage, water purification, ...

Phys.org / A built-in 'hairpin' mechanism in CRISPR-Cas13 prevents rogue RNAs

The CRISPR-Cas gene-editing system has long been the focus of research as a promising tool in genome editing. However, the emphasis has been on its underlying mechanisms and nucleases. In contrast, little research has examined ...

Phys.org / Fluorescent technique reveals hidden scale of microfiber pollution from our clothes

Pollution released from our textiles is smaller and more irregular in shape than previously thought, according to new research led by The University of Manchester. In a study published in Scientific Reports, Manchester researchers—in ...

Phys.org / Torsion balances set strongest direct limits yet on ultralight dark matter

Dark matter is believed to make up a large fraction of the matter in the universe, yet its true nature remains unknown. Most past experiments have focused on heavier dark matter candidates, while much lighter dark matter, ...

Phys.org / Copper blasted into a million-degree plasma strips away 22 electrons in a flash before atoms recover

When laser flashes hit matter, electrons are knocked off their orbits around the atomic nuclei. This can generate extremely hot plasmas composed of charged particles—ions and electrons. Researchers at HZDR have now observed ...
