Phys.org / Toddlers with facial tattoos: How Christianity expanded body art in Nile Valley civilizations
Ancient Nubians who lived between the 7th and 9th centuries tattooed the cheeks and foreheads of their infants and toddlers. This surprising discovery was made during a systematic survey of more than 1,000 human remains from ...
Phys.org / Life's first molecule: Borate boosts its formation, finds study
The transition from simple chemistry to the complex biology of molecules that gave rise to life is a puzzle that scientists have been trying to solve for ages.
Phys.org / Urban birds' beak shape rapidly changed during COVID-19 lockdowns, suggesting human-driven transformations
When the world slowed down during the COVID-19 pandemic, its effects extended beyond humans. A recent study found that it reshaped urban ecosystems to such an extent that certain city-dwelling birds even began to develop ...
Phys.org / Active thermal metasurfaces amplify heat signatures by a factor of nine
Light undergoes a unique phenomenon called superscattering, an optical illusion where a very small object scatters far more light than expected. This happens when multiple scattering modes overlap and interact, allowing tiny ...
Phys.org / A new family of barium-based crystals reveals rules for structural changes
The ultimate goal of materials scientists is to design and create materials with precise structures and tailored properties. Predictive technologies have advanced significantly with the rise of AI, yet the delicate nature ...
Phys.org / Femtosecond laser technique captures elusive atomic oxygen in water
A never-before-seen image of individual oxygen atoms dissolved in water has been captured.
Phys.org / High-energy photons drive conversion of greenhouse gases into high-value chemicals, no catalyst needed
Scientists have found a way to turn carbon dioxide and methane, the two most notorious greenhouse gases, into useful chemicals without any expensive catalysts, using only light.
Phys.org / Used cooking oil yields super strong glue and recyclable plastics
Plastics are made from crude oil and petroleum by-products, so a team of scientists decided to explore if they could turn waste cooking oil into a useful plastic material, and they succeeded.
Medical Xpress / Breastfeeding while on antidepressants does not affect a child's IQ, long-term study finds
Breastfeeding mothers can feel reassured by new research that has found that taking antidepressant treatment does not negatively impact their baby's brain development.
Medical Xpress / Ozempic can reduce metabolic risks in schizophrenia patients, multicenter study finds
Semaglutide medications like Ozempic and Wegovy can help lower the risk of heart and metabolic diseases in people with schizophrenia spectrum disorders, according to a study published in JAMA Psychiatry.
Phys.org / Implantable sensor uses engineered bacteria for wireless molecular tracking
Scientists from Turkey have designed a next-generation implantable biosensor using genetically engineered E. coli for molecular-level monitoring within the body that runs on its own, wirelessly, with no external batteries ...
Phys.org / Silver nanoparticles built on viral biotemplate kill more bacteria and slow resistance rise
Antibiotics are no longer able to treat infections as effectively as they once did because many pathogens have developed resistance to these drugs. This phenomenon, known as antimicrobial resistance (AMR), claims over a million ...
Phys.org / Archaic humans were strategic and picky hunters, new study suggests
Extinct relatives of modern humans, like Neanderthals and Homo erectus, that lived in the Levant around 120,000 years ago, did not engage in mass hunting but preferred selective and strategic hunting of wild cattle. Scientists ...
Phys.org / New palladium-gold alloy catalyst boosts methane-to-ethylene conversion with solar power
Researchers just hit two benefits with one catalyst. They converted methane (CH4), a potent greenhouse gas, into ethylene (C2H4), a highly demanded raw material in industrial sectors, using sunlight and a newly designed palladium–gold ...
Phys.org / New discoveries reveal Tell Abraq's role in ancient Persian Gulf trade
If there were a place that could be called the archaeological almanac of Saudi Arabian culture, it would be Tell Abraq, located on the west coast of the United Arab Emirates. This area contains traces of every cultural phase ...
