Deaths related to air pollution have fallen by an estimated 40% in London in the five years since 2019, according to new analysis.The city’s mayor, Sadiq Khan, welcomed “overwhelming evidence” that ultra-low emission zones save lives.The figures come from a study by Imperial College London, which found that toxic air pollution in London had fallen significantly, with nitrogen dioxide levels falling by 41% and particulate pollution by 28%.Imperial researchers said the latest scientific evidence shows air pollution has a greater impact on health than previously recognized, with previous estimates putting air pollution at risk for 4,000 premature deaths in 2019.This…

The Upper Colorado River Commission welcomed a new representative from New Mexico to a meeting in downtown Denver on Tuesday to discuss ongoing negotiations over how to share the nation’s most over-allocated river. Tanya Trujillo, deputy state engineer and senior water policy advisor to New Mexico Governor Michelle Grisham, has replaced Esteban López as the state’s top negotiator for the Colorado River, which supplies water to seven western states, 30 tribes and 40 million people in Mexico. Trujillo served as assistant secretary for water and science at the Department of the Interior under President Joe Biden. Although she has never…

People who experience intense, obsessive fantasies that disrupt their daily lives have higher rates of co-occurring mental health conditions. A recent comprehensive review published in the International Journal of Psychology found that this immersive habit is strongly associated with a wide range of psychological distress. This study suggests that maladaptive daydreaming deserves formal recognition by psychiatric professionals. Daydreaming is usually a normal psychological process. Most people regularly experience their minds wandering to fun or imaginative scenarios. This common mental activity can even enhance creativity and everyday problem-solving skills in healthy people. However, a portion of the population experiences mutations that…

Scientists have identified a previously unrecognized bird species in Japan after genetic research revealed that what was thought to be a single species is actually two species. The discovery involves the Japanese warbler, a rare migratory bird found only on two island groups in Japan. New species of birds are described every year, but this case stands out because the birds look almost the same. Instead, DNA evidence provided the strongest evidence that they belonged to a different species. “This shows how important it is to use genetic methods to uncover hidden biodiversity during a global biodiversity crisis. These methods…

Diabetic foot ulcers (DFU) are one of the most serious complications of diabetes and a leading cause of lower extremity amputations. Successful wound healing relies on tightly coordinated inflammation, fibroblast proliferation, extracellular matrix remodeling, and tissue remodeling. However, in diabetes, hyperglycemia and metabolic stress can lead fibroblasts to undergo cellular senescence and release persistent senescence-associated secretory phenotype (SASP) factors that damage the wound environment. RNA-binding proteins (RBPs), which control RNA stability and gene expression, are novel regulators of tissue repair, but their role in DFU remains unclear. Based on these questions, detailed studies are needed to elucidate how RNA-binding proteins…

Long-term exposure to nicotine not only increases the desire for the drug itself, but also rewires certain brain circuits, dramatically increasing motivation to work for food. These findings help explain how tobacco use alters how individuals perceive natural rewards and point to potential mechanisms behind non-drug behavioral problems such as overeating and gambling in smokers. The study was published in the journal biological psychiatry. The brain processes motivation and reward through a network of specialized areas that communicate via chemical messengers. Dopamine is the most prominent of these messengers. It is primarily produced by a cluster of cells known as…

Cambridge researchers have shown that there are three different subtypes of severe pneumonia, helping to explain why some patients in intensive care units (ICUs) recover from the disease faster than others, while for others the disease can be life-threatening. Their findings could help inform personalized treatments in the future, ensuring each patient receives the most appropriate treatment. Pneumonia is the most common infectious cause of death worldwide, killing an estimated 2.5 million people annually. In severe cases, patients may be admitted to the ICU and require a ventilator. Six out of 10 infections managed in intensive care units are severe…

Scientists at the SETI Institute have completed a search for a possible technological signal coming from 3I/ATLAS, the third known interstellar object to transit our solar system. Researchers used the Allen Telescope Array (ATA) at Hat Creek Radio Astronomy Observatory in Northern California to scan a wide range of radio frequencies for evidence of extraterrestrial technology. As expected based on previous observations, they found no sign of an artificial signal, further supporting the conclusion that 3I/ATLAS is a natural comet-like object. First seen in July 2025, 3I/ATLAS is the third confirmed interstellar object ever observed to enter the solar system.…

A night without sleep increases markers of connectivity between brain cells, suggesting that sleep in humans may be important in restoring the brain’s cellular balance, according to research published June 23 in an open access journal. PLOS Biology By David Elmenhorst and colleagues at the Jülich Institute for Neuroscience and Medicine in North Rhine-Westphalia, Germany. Scientists have long wondered why humans and other animals need to sleep. One possible mechanism is that sleep is necessary to restore synaptic connections and homeostasis in the brain. Synapses (connections between brain cells) are strengthened during wakefulness. This increases the amount of energy required…

A new Rutgers study suggests that many of the seemingly endless and complex medical wait times can be avoided by recreating operations in a computer and testing countless potential improvements. research in Operations Research Annual Report Researchers at Rutgers Cancer Institute and Rutgers Business School have built a working computer simulation of the institute’s blood cancer clinic and describe how they used it to identify and fix bottlenecks that caused patients to wait up to three hours between check-in and treatment. Subsequent changes have reduced the turnaround time for blood tests in the lab from about 90 minutes to less…
