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 ...
Medical Xpress / CRISPR takes a bold leap toward silencing Down syndrome's extra chromosome
Scientists have taken an important step toward a gene therapy that could one day turn off the extra genetic material that causes Down syndrome (DS). Down syndrome is a genetic condition caused by an extra chromosome 21 (and ...
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 ...
Medical Xpress / Newly discovered neural connections in fruit flies reveal that inhibitory neurons can also drive movement
Researchers at UC Santa Barbara are coming ever closer to uncovering the neural circuitry that translates stimulus to action, shining light on previously unseen neural connections and lesser-known functions of neurons that ...
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 ...
