Medical Xpress / Scientists track real-time signaling in T cell activation to show how the immune system defends against threats
T cell activation—the process by which these key immune defenders recognize threats and mobilize against them—depends on exquisitely timed molecular signals. Now researchers have captured one of the earliest moments of ...
Tech Xplore / Drone video from inside a Fukushima reactor shows a hole in pressure vessel, likely fuel debris
A video taken by tiny drones sent into one of three damaged reactors at the Fukushima Daiichi nuclear power plant showed a gaping hole in the thick-walled steel container of the core, with lumps of likely melted fuel debris ...
Phys.org / AI shows promise for flood forecasting and water security in data scarce regions
New research reveals that "foundation models" trained on vast, general time-series data may be able to forecast river flows accurately, even in regions with little or no local hydrological records. The approach could improve ...
Phys.org / Carefully controlled atoms make renewables more viable for plastics and fuels production
A catalyst developed by a Washington State University research team efficiently converts abundant, renewable ethanol into valuable molecules needed for production of plastics, fuels, and everyday products. The advance could ...
Phys.org / Most mass spectrometers can process just a few molecules at once: Reengineered prototype does a billion simultaneously
Mass spectrometry is already a powerful tool for determining what kind and how many molecules are present in a given sample. But most instruments still analyze their molecules one or just a few at a time, an approach that ...
Phys.org / Nanodiamonds and beyond: Designing carbon materials with AI at exascale
Carbon forms the graphite in pencils, the diamonds in jewelry and the molecules that make up every living thing. But under extreme conditions—like the heat and pressure of intense explosions—carbon can transform into ...
Phys.org / Experiment challenges hypothesis of cell-like membranes on Titan
New experimental results have cast doubt on earlier proposals suggesting that spherical, cell-like membranes could form in the methane lakes of Saturn's largest moon. Through results published in Science Advances, Tuan Vu ...
Medical Xpress / Psilocybin combined with psychotherapy shows significant efficacy in treatment-resistant depression
There is an urgent need for new and more effective treatments for depression. The results of a recent study show that psilocybin, an active compound found in certain mushrooms, can have a significant antidepressant effect. ...
Phys.org / New DNA evidence reveals the complex origin of Palau's first settlers
A new genetic study published in the journal Cell is filling in some important details about the earliest inhabitants of Palau, an island nation in the western Pacific Ocean consisting of approximately 340 islands.
Tech Xplore / Humans and AI must form a cognitive alignment to work well together, say researchers
In the iconic Star Wars series, captain Han Solo and humanoid droid C-3PO boast drastically contrasting personalities. Driven by emotions and swashbuckling confidence, Han Solo often ignores C-3PO's logic-driven caution. ...
Tech Xplore / New X-ray vision for electronics lets scientists monitor working chips remotely
A team of international researchers have developed a breakthrough way to observe what is happening inside electronic chips while they are operating—without touching them, taking them apart, or switching them off. The new ...
Phys.org / Building a better, more precise droplet
A humble droplet can be an immensely useful tool for a number of fields, from medicine to manufacturing. Controlling the size of the droplet, though, is an important—and very tricky—task. With unprecedented precision, ...
