Phys.org / Morocco's hidden history: Archaeology, DNA and carbon dating rewrite the story of the ancient world
For decades, stories about the ancient Mediterranean have centered on the grand cultures of Greece, Rome, Phoenicia and Egypt. Northwest Africa seldom enters the picture before the arrival of Phoenician traders on the Moroccan ...
Phys.org / Ultrafast X-rays allow researchers to 'watch' how molecules rearrange during a chemical reaction controlled by light
Since the 1980s, researchers have sought to use laser light to control chemical reactions relevant to photochemistry, catalysis and light-responsive materials. But this technique, known as coherent control, has a blind spot: ...
Phys.org / Quantum mechanics theory may work without imaginary numbers, new analysis suggests
Physicists from Heinrich Heine University Düsseldorf (HHU) have examined a fundamental property of quantum mechanics in collaboration with the German Aerospace Center (DLR). In an article published in the journal Physical ...
Medical Xpress / Robust colorectal cancer signature identified in large-scale microbiome study
Researchers have long suspected that the gut microbiome—the community of bacteria and other microorganisms living in the intestine—is closely linked to colorectal cancer. In a new study published in Cell Host & Microbe, an ...
Medical Xpress / What one sleepless night does to brain connections and why sleep may reset them
A night without sleep produced increased markers of connections between brain cells, showing that sleep in humans may be important for restoring cellular balance in the brain, according to a study published in PLOS Biology ...
Phys.org / Looking at AI startups to predict which jobs AI will affect
A study of funded AI startups provides a glimpse of which jobs may be most affected by AI. As AI tools are embraced by industry after industry, the impacts of these tools on jobs remain unclear. Previous analyses have focused ...
Phys.org / What made prehistoric communities resilient? Ancient social networks may hold the answer
A new study led by Dr. Ariel Malinsky-Buller of the Hebrew University of Jerusalem challenges long-held assumptions about how prehistoric hunter-gatherers survived in the Southern Caucasus between 57,000 and 27,000 years ...
Medical Xpress / Bandage-like device delivers hydrogen sulfide to wounds, boosting blood flow where healing stalls
For most people, a blister or small cut is an inconvenience. For others, it can become something much more serious.
Medical Xpress / Immune cell–fibroblast crosstalk may be the key trigger of autoimmune diseases
In autoimmune disorders, immune cells targeting "self" proteins are mistakenly activated, resulting in abnormal expansion and responsiveness. These disorders are known to reduce patients' quality of life over a prolonged ...
Phys.org / Electron buildup at 2D interface reveals how Janus semiconductors form at room temperature
Researchers at Tohoku University have uncovered the long-standing mystery behind the synthesis of Janus two-dimensional (2D) semiconductors, paving the way for more precise manufacturing of materials used in future electronics ...
Phys.org / California has lost more than half of its coastal sand dunes, first-ever assessment reveals
A study conducted by UC Santa Barbara researchers and collaborators has found that California has lost more than half of its coastal dune systems. The researchers' assessment—the first of its kind for the California coast—estimates ...
Phys.org / Greece says preparing 'historic' ISS space mission
Greece is planning "a first historic mission" to send a Greek astronaut to the International Space Station, Prime Minister Kyriakos Mitsotakis' office announced Friday.
