Phys.org / First-ever shark recorded in Antarctic waters filmed at 490 meters in near‑freezing water
An ungainly barrel of a shark cruising languidly over a barren seabed far too deep for the sun's rays to illuminate was an unexpected sight.
Phys.org / Germany's coastal regions brace for change, fearing rising sea levels
Standing on the coast and looking out to sea, you cannot detect the changes with the naked eye. But in northern Germany, sea levels are rising, as is the risk of flooding for the lower-lying coastal regions.
Phys.org / Metamaterial image sensor keeps colors clear even under oblique light
Smartphone cameras are becoming smaller, yet photos are becoming sharper. Korean researchers have elevated the limits of next-generation smartphone cameras by developing a new image sensor technology that can accurately represent ...
Phys.org / Students run 'bee hotels' across Canada—DNA reveals who's checking in
Can students be on the front lines of conservation? A new Canada-wide study, published in Metabarcoding and Metagenomics, suggests they can. The efforts of some 5,000 students produced data detailed enough to reveal complex ...
Phys.org / Trauma follows children into the classroom—a new teaching model is changing that
Traumatic experiences can have ripple effects that permeate across many aspects of people's lives. For students, adverse childhood experiences have been shown to impact attention, memory, language development and relational ...
Phys.org / Image: Curiosity rover surveys boxwork region of Mars
NASA's Curiosity Mars rover captured this panorama of boxwork formations—the low ridges seen here with hollows in between them—using its Mastcam on Sept. 26, 2025, the 4,671st Martian day (sol) of the mission. These boxwork ...
Phys.org / How early farming unintentionally bred highly competitive 'warrior' wheat
An evolutionary "arms race" for light and space led to the early domestication of wheat, according to new research that could offer fresh insights into crop design. The study led by Dr. Yixiang Shan and Professor Colin Osborne, ...
Phys.org / The cooling system that lets bees beat the heat when hovering
To stay in the air when hovering over a flower, bumble bees continually flap their wings rapidly, a metabolic process that generates a massive amount of internal heat. Their flight muscles work so intensely that they can ...
Medical Xpress / DeepRare AI outperforms doctors on rare disease diagnosis in head-to-head test
Rare diseases are complex medical disorders that are notoriously difficult to diagnose because many present with a wide variety of symptoms that can overlap with more common illnesses. Currently, around 300 million people ...
Medical Xpress / Women may face heart events at lower plaque levels than men, study finds
Less artery-clogging plaque in women's arteries did not appear to protect them from heart disease compared to men, according to a study published in Circulation: Cardiovascular Imaging. While heart disease is the leading ...
Medical Xpress / People prefer the empathy of humans, but rate 'fake' AI empathy higher
Artificial Intelligence (AI) agents, particularly the large language models (LLMs) underpinning the functioning of ChatGPT and other popular conversational platforms, are now used daily by millions of people worldwide. As ...
Phys.org / Warming Antarctic waters come with a cost for the 'robust' rockcod
About 10 million years ago, Antarctica's Southern Ocean started to get so cold that it scared away most fish in the region. Among the fish that stayed were what are now known as black rockcod, part of a famously sturdy family ...
