Phys.org / New chip-scale microcomb uses lithium niobate to generate evenly spaced light
Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have discovered a new way to generate ultra-precise, evenly spaced "combs" of laser light on a photonic chip, a breakthrough ...
Medical Xpress / Mechanism behind immunotherapy resistance in lung cancer identified
Mayo Clinic researchers and collaborators have identified a previously unrecognized way lung tumors weaken the immune system, helping explain why many patients do not respond to immunotherapy and pointing to a potential new ...
Phys.org / AI system TongGeometry generates and solves olympiad-level geometry problems
The International Mathematical Olympiad (IMO) is a prestigious competition featuring talented high school students from around the world, in which competitors solve complicated mathematical problems. Geometry problems from ...
Phys.org / Linguist explains how AI makes fake news more credible
Fake news generated by AI is often perceived as more credible than texts written by humans. That worries linguist Silje Susanne Alvestad. In 2017, "fake news" was chosen as the new word of the year by the Language Council ...
Phys.org / Archived tree cores reveal why boreal forests are getting starved for nitrogen
Despite decades of industrial deposition, nitrogen availability in the boreal forest is steadily declining. In a new study published in Nature, researchers from the Swedish University of Agricultural Sciences using decades ...
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.
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 / Why some objects in space look like snowmen: Gravitational collapse may shed light on contact binaries
Astronomers have long debated why so many icy objects in the outer solar system look like snowmen. Michigan State University researchers now have evidence of the surprisingly simple process that could be responsible for their ...
Phys.org / Nature-inspired method forms ZnO quantum dots in solid crystals at room temperature
In nature, tiny crystals known as nanocrystals are formed slowly over many years. Rocks and minerals react with air, water, and carbon dioxide in a process called chemical weathering. These reactions happen gently, at room ...
Phys.org / Is this glass square the long, long future of data storage?
Scientists at Microsoft Research in the United States have demonstrated a system called Silica for writing and reading information in ordinary pieces of glass which can store two million books' worth of data in a thin, palm-sized ...
Medical Xpress / Epstein-Barr: The virus nearly everyone carries and its possible role in MS
Over 95% of the world's adult population is infected with Epstein-Barr virus (EBV), but most people never realize it. The infection often causes few symptoms and then stays in the body for life.
Phys.org / Cheaper green hydrogen? New catalyst design cuts energy losses in AEM electrolyzers
Producing clean hydrogen from water is often compared to storing renewable energy in chemical form, but improving the efficiency of that process remains a scientific challenge. Researchers at Tohoku University have now developed ...
