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 / Espresso 'pucks' stop behaving predictably above certain pressures
When a physics student asked baristas at the Warsaw Coffee Conference what their biggest question for scientists was, the baristas said they wanted to know how to stop channeling during brewing.
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 / Why Ho Chi Minh City's pollution sources may have been misread for years
Biomass burning, including the combustion of wood, charcoal and agricultural residues, is a major source of PM2.5, a fine particulate matter that degrades air quality and poses risks to human health. Much of this pollution ...
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.
Phys.org / Axolotl-inspired skin matrix may help heal wounds with less scarring
Researchers in Taiwan have developed a cell-free extracellular matrix material from axolotl skin that helped mouse burn wounds close faster and show signs of reduced fibrotic scarring. The findings suggest that one of nature's ...
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 / Graphene plasmon cavities enable advanced and scalable terahertz photodetectors
How could we noninvasively distinguish between healthy and cancerous tissue? And how could we increase the speed of wireless communications? These two seemingly unrelated questions may share the same answer: terahertz (THz) ...
Tech Xplore / Smarter optimization model could cut bridge and building materials by up to 90%
In 2022, global production of construction materials accounted for more than 7% of total carbon emissions. But how many of those materials were truly necessary to build houses, buildings and bridges?
Phys.org / Modeling nuclear fusion at lightning speed
As we scour and scorch the Earth for deeper wells of energy, investors and government agencies are pouring billions into nuclear fusion research. The hope is that fusion may ultimately provide a virtually limitless source ...
