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 / PFAS concentrations can double with every step up the food chain
A new UNSW-led global meta-analysis shows that PFAS concentrations can double at every step up the food chain, leaving top predators—and humans—potentially exposed to higher chemical loads.
Phys.org / New technique lights up where drugs go in the body, cell by cell
When you take a drug, where in your body does it actually go? For most medications, scientists can make only educated guesses about the answer to this question. Traditional methods can measure the concentration of a drug ...
Medical Xpress / Immune cell 'fuel' shortages shape atherosclerosis, scientists reveal
Two complementary studies reveal how an insufficient supply of energy in macrophages, key immune cells in artery walls, drives the progression of atherosclerosis—and how this knowledge could lead to better diagnostics and ...
Tech Xplore / New computer vision method links photos to floor plans with pixel-level accuracy
For people, matching what they see on the ground to a map is second nature. For computers, it has been a major challenge. A Cornell research team has introduced a new method that helps machines make these connections—an ...
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 / Supermassive black holes show selective feeding habits during galaxy mergers
Black holes are notorious for gobbling up everything that comes their way, but astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered that even supermassive black holes can be picky eaters, ...
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 ...
Medical Xpress / 'Listening in' on the brain's hidden language: Engineered protein detects the faintest incoming signals
Scientists have engineered a protein able to record the incoming chemical signals of brain cells (as opposed to just their outgoing signals). These whisper-quiet incoming messages are the release of the neurotransmitter glutamate, ...
Phys.org / Nanoplastics have diet-dependent impacts on digestive system health, study finds
Plastics are not inert: they gradually break into fragments over time, forming micro- and then nanoplastics (i.e., particles
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.
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.
