Tech Xplore / Waymos blocked roads and caused chaos during San Francisco power outage
Many of Waymo's self-driving cars blocked streets of San Francisco during a mass power outage Saturday and forced the company to temporarily suspend service, raising questions about the cars' ability to adapt to real-world ...
Phys.org / Kolmogorov-Arnold networks bridge AI and scientific discovery by increasing interpretability
AI has successfully been applied in many areas of science, advancing technologies like weather prediction and protein folding. However, there have been limitations for the world of scientific discovery involving more curiosity-driven ...
Phys.org / How chirality goes from the molecular level to the cellular one
RIKEN researchers have discovered how right-handed molecules in our cells can give rise to cells that are not symmetrical about their central axes. This discovery is a key step toward determining why most of our organs lack ...
Phys.org / Vast freshwater reserves found beneath salinity-stressed coastal Bangladesh
Despite its tropical climate and floodplain location, Bangladesh—one of the world's most densely populated nations—seasonally does not have enough freshwater, especially in coastal areas. Shallow groundwater is often ...
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.
Medical Xpress / School meals could unlock major gains for human and planetary health
Healthy, sustainable school meals could cut undernourishment, reduce diet-related deaths and significantly lower environmental impacts, according to a new modeling study led by a UCL (University College London) researcher.
Phys.org / How does Santa do it all? Quantum physics, that's how, says scientist
Every year, Santa Claus races around the globe in a matter of hours to bring presents to children all over the world.
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 / For teens, any cannabis use may have impact on emotional health and academic performance
Using marijuana just once or twice a month was associated with worse school performance and emotional distress for teens, according to a large national study of adolescents led by Ryan Sultán, an assistant professor of clinical ...
Phys.org / Predictive 'mismatch' leads to novel carbon capture method
When experimental results don't match scientists' predictions, it's usually assumed that the predictions were wrong. But new research into materials that pull carbon dioxide directly from the air shows how such mismatches ...
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 / 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, ...
