Tiny rubber particles thrown off by car tires have long been known to harm wildlife, but new research shows they can also pose a danger to humans.6PPD, a chemical added to tires to prevent cracking, changes when exposed to ozone pollution from car exhaust. One of the compounds produced in this process, 6PPD-quinone, is thought to be involved in the death of spawning coho salmon in the Pacific Northwest. For decades, heavy rains have flushed contaminated rainwater into urban waterways, causing salmon deaths to skyrocket.New research has found that many other chemicals derived from tire wear can pose a threat…
A comprehensive analysis of more than 800 studies questions the idea of a universal “safe” drinking limit and found stronger evidence for alcohol-related harms than uncertain health benefits. Research: Health effects associated with alcohol consumption: Burden of proof study. Image credit: Shchus / Shutterstock In a comprehensive review recently published in the magazine natural healthresearchers synthesized the complex and often contradictory evidence on alcohol consumption and human health. This review analyzed data from over 800 observational studies and mapped statistically supported risk levels for 20 different diseases, including various cancers and cardiovascular diseases. Research has found that while light drinking…
A new study shows how unlocking a regular phone could eventually support passive heart rate tracking, using facial video and deep learning to make cardiovascular monitoring more accessible, while raising important questions about accuracy, privacy, and real-world clinical use. Research: Passive heart rate monitoring during smartphone use in daily life. Image credit: Have a nice day Photo/Shutterstock Smartphones will soon automatically track heart health while people use their smartphones normally, without the need for smartwatches, fitness trackers, or intentional heart rate checks. In a large study published in the journal natureresearchers created a passive heart rate monitoring (PHRM) system that…

Young children often learn how to process their emotions simply by watching their parents interact. A recent study published in the journal Neuroscience found that when young girls observed their parents discussing their relationship, their brain activity synchronized with that of their mothers. The researchers found that this shared neural response was associated with reduced emotional difficulties in children, highlighting the hidden ways in which the family environment shapes early mental health. Children’s emotional development sets the stage for their future well-being and academic success. Social skills in early childhood often predict how well a person will cope with stress…
Recent research examines how dark personality traits and moral judgments combine to shape the mindset of militant extremists. This research shows that people who advocate ideological violence often exhibit sadistic tendencies and prioritize group loyalty over personal fairness. These findings were published in the journal Personality and Individual Differences. Psychologists typically define extremist thinking as a particular pattern of beliefs and motivations. Rather than viewing extremists simply as deviant personalities separated from normal society, researchers treat this idea as a combination of attitudes that can be activated under the right environmental conditions. This cognitive pattern contains three main elements, which…
Black said aquatic insects are essential to our landscapes, as well as pollinators that Americans are interested in supporting. However, they do not enjoy the same popularity.Freshwater mollusks that live in U.S. rivers filter water. Black said if the river were cleaner, water utilities wouldn’t have to spend as much money on treatment.In addition to deficiencies in existing pollution control laws, Black sees a risk of rolling back enforcement of those laws and other federal environmental measures.”What worries me is that we’re losing staff across the board. All agencies that are responsible for conservation in some way are losing staff,”…
Wearable ownership in the U.S. has increased by 33% since 2015, according to a new analysis from Rock Health. In the 2025 Digital Health Consumer Adoption Survey, 46% of respondents specifically reported owning a wearable, and 57% of respondents reported owning at least one wearable or other connected device. However, the report notes that the growth in first-time wearable users is slowing. Smart watches remain the most popular device among the 8,000 survey respondents, with 43% reporting owning one. Other popular devices include smart scales (13%), connected blood pressure cuffs (13%), continuous blood glucose monitors (9%), and smart rings (8%).…
Recent research is Journal of Psychopharmacology This suggests that psychedelic substance use does not reliably change authoritarian political attitudes. These findings contrast with previous reports showing that psychedelic drugs can weaken individuals’ authoritarianism, and provide evidence that such psychological changes are likely inconsistent and dependent on other unknown factors. Psychedelics are a type of psychoactive substance that can cause significant changes in perception, mood, and cognitive processes. Common examples include psilocybin, the active compound in magic mushrooms, and lysergic acid diethylamide, commonly known as LSD. These drugs interact with the brain’s serotonin system, which helps regulate mood and human perception.…
Women who have an abnormal mammogram often have to wait several weeks to find out if they have breast cancer. Now, researchers at the University of California, San Francisco and the University of California, Berkeley have discovered a way to reduce wait times and anxiety by using AI to quickly identify those most likely to contract the disease. By triaging these patients, AI-guided workflows can complete the diagnostic process from imaging to evaluation and even biopsy in a single day. “This is a really exciting time,” said Maggie Cheung, MD, lead author of the study published May 19. nature digital…
