Phys.org / Portugal burial reveals first known bone dental bridge in national archaeological record
The first documented case of a fixed bone bridge unearthed in Portugal was presented in the International Journal of Osteoarchaeology by researchers Ms. Steffi Vassallo and her colleagues. The item is estimated to date to ...
Phys.org / Something coming: what scientists know about a potential 'super' El Nino
Forecasters say a potentially "super" El Niño is rapidly taking shape in the Pacific—but whether it evolves into a history-making event could hinge on fickle winds and other volatile atmospheric shifts.
Phys.org / How a 4,000-year-old city defied history's 'rules' by becoming more equal as it became more successful
For decades, historians have generally agreed that the progress of small villages as they evolved into cities came at the price of widening inequality. A small group of leaders, kings and priests, would inevitably seize control ...
Tech Xplore / Could anything but profit steer AI? The OpenAI trial offered clues but no verdict
The trial pitting Elon Musk against OpenAI CEO Sam Altman made clear the two billionaires agreed on one thing: building artificial intelligence would require significant resources—and enormous amounts of money.
Phys.org / Nickelate reveals nodeless gap, providing key clue to high-temperature superconductivity
The mechanism of high-temperature (TC) superconductivity is a key challenge in condensed matter physics. Recently, Chinese scientists made significant progress in the study of high-TC nickelate superconductors.
Phys.org / Scientists discover thriving hard-substrate fauna in Oceania's deep sea
In the crushing darkness of the hadal zone—deep ocean trenches plunging 6,000 m to nearly 11,000 m—scientists have uncovered a hidden community. A study published in Science on May 14 reports the discovery of a protist-dominated ...
Phys.org / Key switch controlling soil fungi symbiosis could solve a longstanding agricultural problem
Over the course of evolution, plants have developed an elegant strategy to counteract a lack of phosphate in the soil—they form symbiotic relationships with soil fungi. These mycorrhizal fungi efficiently supply their plant ...
Medical Xpress / How state laws can stymie research into your ancestors' psychiatric records
Breta Meria Conole was in a state psychiatric hospital for more than two decades. But the reason why is a family mystery.
Medical Xpress / Good dog! More children's hospitals turn to furry caregivers to help kids heal
The first time 5-year-old Calvin Owens went outside in more than a month, he met up with his canine friend Hadley on a hospital patio. Despite being tethered to equipment with wires and tubes, the little boy managed to stand ...
Phys.org / Understanding the mechanisms of collective cell movement
Like schools of fish and flocks of birds, our cells can also migrate collectively in coordination with their neighbors. This harmonious movement of cells occurs during embryonic development, wound healing, and cancer metastasis. ...
Phys.org / Some technologies use accelerated natural processes to capture carbon, but can they store it durably?
Natural geological processes have been regulating Earth's climate for millions of years. Accelerated versions of these processes are now being promoted as technologies to draw down carbon from the atmosphere—and some are ...
Phys.org / Atlas reveals rocks with rare earth element potential, helping pinpoint new deposits
A new atlas charts the global distribution of unusual, critical-metal-bearing igneous rocks, finding that they often form near the thick and ancient cores of the world's major continents. Researchers from Cambridge's Department ...
