Phys.org / Why mysterious structures within Earth's mantle hold clues to life here
For decades, scientists have been baffled by two enormous, enigmatic structures buried deep inside Earth with features so vast and unusual that they defy conventional models of planetary evolution.
Phys.org / Looking inside a well-preserved Neanderthal nose to solve a mystery about our ancestors' faces
A long-standing debate in paleontology about whether the distinctive Neanderthal nose evolved purely for the cold weather may have finally been solved, and it's all thanks to an ancient, exceptionally preserved nasal cavity.
Phys.org / Humans are evolved for nature, not cities, say anthropologists
A new paper by evolutionary anthropologists Colin Shaw (University of Zurich) and Daniel Longman (Loughborough University) argues that modern life has outpaced human evolution. The study suggests that chronic stress and many ...
Phys.org / Video catches wild wolf pulling in crab trap to get to food—but is it tool use?
Many animals have been observed using tools. For example, chimps tear leaves off of branches and stick them into holes to pull out termites, and wild dingoes have been observed moving objects to stand on to get to another ...
Phys.org / Quantum teleportation between photons from two distant light sources achieved
Everyday life on the internet is insecure. Hackers can break into bank accounts or steal digital identities. Driven by AI, attacks are becoming increasingly sophisticated. Quantum cryptography promises more effective protection. ...
Phys.org / Deep imaging suggests isolated galaxy forms stars without signs of past mergers
Using the Two-meter Twin Telescope (TTT3), Spanish astronomers have conducted deep optical imaging of an isolated dwarf galaxy known as NGC 6789. Results of the new observations, presented November 10 on the arXiv preprint ...
Phys.org / New synthesis strategy for (–)-gukulenin A reveals the chemistry behind its anticancer effects
A team of researchers from Yale University, U.S., successfully achieved the first stereoselective synthesis of the complex natural product (–)-gukulenin A (7), which exhibits notable cytotoxicity against ovarian cancer.
Phys.org / Archaeologists reveal second-largest Roman olive oil mill in the Roman Empire
Ca' Foscari University of Venice is co-directing a major international archaeological mission in the Kasserine region of Tunisia. The excavations, focused on the area of ancient Roman Cillium, on the border with present-day ...
Phys.org / Social media use soars as kids drop sports, reading and the arts
In striking new statistics, experts warn of social media's growing grip on young people, with use among children and teens soaring by more than 200% since before COVID and showing no sign of decline.
Phys.org / How most of the universe's visible mass is generated: Experiments explore emergence of hadron mass
Deep in the heart of the matter, some numbers don't add up. For example, while protons and neutrons are made of quarks, nature's fundamental building blocks bound together by gluons, their masses are much larger than the ...
Phys.org / Enzyme-free approach gently detaches cells from culture surfaces
Anchorage-dependent cells are cells that require physical attachment to a solid surface, such as a culture dish, to survive, grow, and reproduce. In the biomedical industry, and others, having the ability to culture these ...
Phys.org / Disputed Jordan codices reveal age variations under ion-beam scrutiny
Scientists have delivered the most detailed assessment yet of a set of disputed lead books known as the Jordan codices. With debate centered on whether they could date back to the early Christian period, a study led by the ...
