Jun Zhang and colleagues have published a new article in Urban Geography arguing that urban AI should not be understood as a single, inevitable next stage of the smart city. Instead, it shows that AI urbanism is a contested political and discursive formation—a set of
Caltech scientists have developed a new way to produce optical frequency combs—important tools in devices that keep time and measure distances very precisely—at the chip scale, an advance that should make it easier to incorporate such combs in optical devices and more practical
New research from the University of St Andrews has revealed that human readiness for intergroup violence is not a single or unified mindset. Published in the Proceedings of the National Academy of Sciences, the new study, spanning 58 countries and involving more than 100
Scientists from National Taiwan University (NTU) and Linkou Chang Gung Memorial Hospital (CGMH) have developed a precision-engineered nanoplatform to conquer glioblastoma (GBM), the most aggressive and deadly form of brain cancer. Treating glioblastoma is notoriously difficult
In back-to-back studies published in Nature, researchers from Purdue University and Columbia University report a naturally evolved gene-editing system that can activate genes, offering an advantage over existing CRISPR gene-editing systems that merely find and cut DNA. The
As bees and hummingbirds flit from flower to flower, greedily sipping nectar in exchange for pollination, the animals often get another treat: alcohol. In the first broad analysis of the alcohol content of flower nectars, University of California, Berkeley biologists found
History can sometimes take an unexpected turn. One of these curious, revolutionary twists came in the mid-19th century, when the tale of an unassuming everyday object—the billiard ball—ended in cinematic proportions.
In a landmark trial, social media giants Meta and YouTube were found negligent and ordered to pay for harming a user's mental health. The decision could force major changes in how social platforms work
This past winter, the Rocky Mountains experienced an historic snow drought, a worrying development for the tens of millions of people in the arid American West who depend on snowmelt for water. Now, a new study in the journal Geology investigates the geologic history of a
Phonons are the quantum units of mechanical vibration. They describe how motion propagates through a solid at the smallest possible scales, in much the same way that electrons describe electric currents. Because phonons can be exceptionally stable and sensitive, they are used
New images captured by the Hubble and James Webb space telescopes show Saturn in both visible and infrared light
Across much of the Western United States, winter 2026 was the year the snow never came. Many ski resorts got by with snowmaking but shut down their winter operations early. Fire officials and water supply managers are worried about summer.
Dung beetles remove feces from wild animals in forests and thus inhibit the spread of parasites. They work the dung into the soil and thus supply nutrients to plants. They fulfill this task both in European commercial forests and in the Amazon. However, rising temperatures
For the first time, astronomers have directly measured the speed of superheated gas billowing from a cauldron of stellar activity at the heart of M82, a nearby galaxy undergoing an extraordinary burst of star formation. The material is moving more than 2 million miles (over 3
For decades, it has been widely believed that electrons move most efficiently in materials that are clean and highly ordered. Much like water flowing more easily through a smooth pipe, conventional wisdom has held that electrical transport improves as a material's internal

The mass extinction at the boundary between the Cretaceous and Paleogene periods was catastrophic, wiping out much of life on Earth. Vertebrate groups that dominated at the time, such as dinosaurs and many large marine reptiles, fell victim to the effects of the asteroid impact
New research from the Dog Aging Project and Texas A&M University highlights that for many families, losing a dog means losing a family member—and that the grief is profound regardless of how a pet dies. The studies underscore the need for veterinarians to support owners through
