Phys.org / Biophysical model suggests how cells optimize information gathering without using too much energy
In both biological and engineered systems, cells and sensors must make sense of noisy, changing signals to function. However, collecting and using this information consumes valuable energy. A new study, published in Physical ...
Phys.org / Webb reveals dynamic panorama of star formation, including smallest known brown dwarfs
This starry view of the nearby star-forming region IC 348 is one of the largest images released to date from NASA's James Webb Space Telescope. Using Webb, astronomers searched IC 348 for brown dwarfs, which are less massive ...
Medical Xpress / STI rates remain high in Australia's latest sexual health data
New sexual health data released by the Kirby Institute at UNSW Sydney show a mixed picture for Australia, with rates of syphilis and gonorrhea remaining high after significant increases since 2016—and chlamydia stable but ...
Phys.org / Weather forecasts are significantly less accurate in poorer countries, analysis finds
Weather forecasts inform countless everyday decisions—from farmers deciding when to sow crops and energy companies anticipating demand to public authorities preparing for heat waves. But how useful those forecasts are depends ...
Phys.org / Transparency and trust are the foundations of every successful research partnership, report suggests
According to research by the IfM Bonn, strengthening research collaboration between universities and businesses requires regional technology transfer networks in which technology transfer offices at universities and research ...
Phys.org / Study explores new photonics advance: Topology imprinting in nonlinear metasurfaces
Light is traditionally described by properties such as wavelength, amplitude, phase and polarization. Advances in optics have shown that light can also be shaped into complex spatial patterns known as structured light, enabling ...
Phys.org / Plans to artificially dim the sun have divided scientists—here's what they're actually arguing about
No, President Joe Biden did not engineer Hurricane Milton. No, the ice crystal contrails left behind by high-altitude aircraft are not "chemtrails" sprayed by governments to control the weather or manipulate populations. ...
Phys.org / Not all roads lead to Rome: Research challenges what we think we know about Roman roads
A multidisciplinary team of researchers from Aarhus University in Denmark, Queen Mary University of London and other European institutions analyzed a data set representing almost 300,000 kilometers (186,000 miles) of Roman ...
Tech Xplore / AI imagines a harsher social world, expecting punishment where people expect inaction
Artificial intelligence (AI) systems, particularly the large language models (LLMs) that underpin ChatGPT and similar platforms, are remarkably skilled at answering queries about a wide range of topics. However, the extent ...
Medical Xpress / Stable answers help medical AI flag diagnoses clinicians can trust
AI agents could reliably support diagnoses and clinical decision-making in the future—provided sensitive health data are protected and clinicians can assess the reliability of individual AI-generated results. Researchers ...
Phys.org / Disordered atoms steer shared light pulses by matching motion and timing
A research team at the Institute of Applied Physics at TU Darmstadt has shown for the first time that atoms that are completely disordered and in constant motion can nevertheless emit jointly directed light preferentially ...
Phys.org / Why most rivers don't respond to storms the same way twice
The same amount of rain falling on the same landscape at different times can send very different amounts of water into its rivers, according to a new study in Nature Water. The research offers a global picture of how catchments ...
