Phys.org / More than clothing: How ancient needles and awls shaped survival, medicine and ritual
A study led by McKenna Litynski, a Ph.D. graduate in anthropology and adjunct assistant professor at the University of Wyoming, confirms that ancient needles and awls enabled humans to survive in cold climates and shows these ...
Phys.org / Subglacial weathering may have slowed planet's escape from snowball Earth
A new study led by researchers at the Earth-Life Science Institute (ELSI) at Institute of Science Tokyo challenges a long-standing assumption about Earth's most extreme ice ages. Using numerical geochemical models, the team ...
Medical Xpress / Nanohydrogels steer cancer drugs to tumors, aiming to spare healthy tissue
Exhaustion creeps in. Appetite vanishes. Hair thins. The person in the mirror looks gaunt. It's the paradox of cancer treatment: The same drugs meant to save a life can also wear the body down. Nick Housley, assistant professor ...
Phys.org / How changes on the Y chromosome may make species reproductively incompatible
When closely related species mate, their offspring sometimes survive but cannot reproduce. This pattern often affects males first, with hybrid males frequently failing to produce functional sperm even when hybrid females ...
Medical Xpress / Why 'being squeezed' helps breast cancer cells to thrive
A new study led by researchers at Adelaide University and published in Science Advances reveals why some cancers can grow and survive in the body, while others cannot. It turns out that intense mechanical pressure experienced ...
Phys.org / Understanding how wind moves pollen can guide urban planning decisions about green spaces
Due to climate change, plants' pollination season has been growing longer and longer. As a result, people are exposed to allergens for extended periods each year, raising a major public health concern. Researchers from Embry‑Riddle ...
Phys.org / Antarctic sea ice rebounds in 2026, nearing average after four years
Antarctic sea ice coverage has likely rebounded this year, coming closer to its annual summer average after four years of extreme lows, US scientists said Monday.
Phys.org / Subway systems are uncomfortably hot—and worsening, study finds
For millions of commuters, the workday doesn't just begin with a train ride. It also begins with a blast of heat. In one of the largest studies ever conducted on thermal comfort in metro systems, Northwestern University scientists ...
Phys.org / Multi-wavelength observations track bright gamma-ray blazar's three-year cycle
By analyzing the data from various space observatories and ground-based telescopes, European astronomers have performed a multiwavelength study of a bright gamma-ray blazar known as S5 1044+71. The new study, published Feb. ...
Phys.org / Quantum entanglement offers route to higher-resolution optical astronomy
Researchers in the US have demonstrated how quantum entanglement could be used to detect optical signals from astronomical sources at the single-photon level. Published in Nature, a team led by Pieter-Jan Stas at Harvard ...
Phys.org / Raccoons solve puzzles for the fun of it, new study finds
They raid compost bins, outsmart latches and sometimes look gleeful doing it. A new study in Animal Behaviour suggests raccoons may not just be opportunistic—they may be genuinely curious.
Phys.org / Superconductivity controlled by a built-in light-confining cavity
For the first time, physicists have demonstrated that a material's superconductivity can be altered by coupling it to an in-built, light-confining cavity. In experiments published in Nature, a team led by Itai Keren at Columbia ...
