Phys.org / Journey to the center of a quantized vortex: How microscopic mutual friction governs superfluid dissipation
Step inside the strange world of a superfluid, a liquid that can flow endlessly without friction, defying the common-sense rules we experience every day, where water pours, syrup sticks and coffee swirls and slows under the ...
Phys.org / Decades-long quest leads to first scholarly accurate fossil replica of 'dinosaur-killer' croc
Dr. David Schwimmer, an expert on the giant North American crocodilian genus Deinosuchus and a Columbus State University geology professor, has contributed his research to the creation of the first-ever scholarly accurate, ...
Tech Xplore / Lowering barriers to explainable AI: Control technique for LLMs reduces resource demands by over 90%
Large language models (LLMs) such as GPT and Llama are driving exceptional innovations in AI, but research aimed at improving their explainability and reliability is constrained by massive resource requirements for examining ...
Phys.org / Rare Hall effect reveals design pathways for advanced spintronic materials
Scientists at Ames National Laboratory, in collaboration with Indranil Das's group at the Saha Institute of Nuclear Physics (India), have found a surprising electronic feature in transitional metal-based compounds that could ...
Phys.org / Ancient pottery workshop reveals Iron Age production chain
Ceramics are one of the most important sources of information for archaeologists. Yet how these objects are produced, especially in the firing stage, has received little attention to date. The excavation of a well-preserved ...
Phys.org / Hagfish olfactory genes hint at ancient origins of vertebrate sense of smell
Researchers at University of Tsukuba and their collaborators have conducted a comprehensive analysis of the olfactory receptor repertoire of the hagfish (Eptatretus burgeri), a jawless vertebrate. This organism retains many ...
Phys.org / Scalable method enables ultrahigh-resolution quantum dot displays without damaging performance
Over the past decade, colloidal quantum dots (QDs) have emerged as promising materials for next-generation displays due to their tunable emission, high brightness, and compatibility with low-cost solution processing. However, ...
Medical Xpress / Night shifts aren't just tiring, they can be deadly: Disrupted sleep cycles linked to aggressive breast cancer
Working the night shift, frequently flying across time zones or keeping an irregular sleep schedule does more than just leave us exhausted; it can fuel the risk of aggressive breast cancer. Exactly how and why this happens ...
Tech Xplore / Harnessing long-wavelength light for sustainable hydrogen production
A novel dye-sensitized photocatalyst developed at Science Tokyo enables the capture of long-wavelength visible light for efficient hydrogen conversion, surpassing conventional photocatalysts.
Phys.org / Stripe patterns in blood cells offer new clues for diagnosing disorders and understanding natural designs
Stripe patterns are commonly seen in nature—for instance, birds and fish move in coordinated flocks and schools, fingerprints form unique designs, and zebras can be identified by their distinctive stripes.
Phys.org / Why a chiral magnet is a direction-dependent street for electrons
RIKEN physicists have discovered for the first time why the magnitude of the electron flow depends on direction in a special kind of magnet. This finding could help to realize future low-energy devices.
Medical Xpress / Online psychoeducation underperforms existing digital cognitive behavioral therapy in trial
Big Health Inc, along with paid academic investigators, reports higher remission rates and lower anxiety symptom scores with their smartphone-delivered digital cognitive behavioral therapy, DaylightRx, compared with an online ...
