The study, published in the Environmental Science & Technology ...

UNIVERSITY PARK, Pa. — Since the 1960s, scientists who study X-rays, lightning and similar phenomena have observed something curious: In lab experiments replicating these occurrences, electrons accelerated between two electrodes can be of a higher energy than the voltage applied. According to Penn State researchers, this defies an assumption in physics that the energy of the electrons should correspond with the voltage applied. Despite the decades-long awareness of this apparent contradiction, researchers couldn’t ...

Although many tech companies and start-ups have touted the potential of automated fact-checking services powered by artificial intelligence to stem the rising tide of online misinformation, a new study led by researchers at Indiana University has found that AI-fact checking can, in some cases, actually increase belief in false headlines whose veracity the AI was unsure about, as well as decrease belief in true headlines mislabeled as false. The work also found that participants given the option to view headlines fact checked by large language model-powered AI were significantly more likely to share both true and false news – but only ...

Redlining—a mid-20th-century federal government practice of denying home loans in African American and other minority neighborhoods—has long been associated with poor health outcomes, including disparate overall mortality rates among racial and ethnic groups. The term gets its name from the practice by the Home Owners’ Loan Corporation (HOLC, operational from 1933 to 1954) of color-coding maps based on each neighborhood’s level of mortgage creditworthiness, with A being the most creditworthy and D—noted with a red line—the least. Now, a new study led by a researcher with the Texas ...

WHAT: Researchers at the National Institutes of Health (NIH) found previously undetected cancers in 48.6% of pregnant people who had abnormal results for prenatal cell-free DNA (cfDNA) testing used to screen for chromosomal disorders in the fetus. Cancers included colorectal, breast, lung and pancreatic cancers, as well as lymphoma, cholangiocarcinoma and renal carcinoma. The screening test analyzes placental DNA fragments circulating in the maternal bloodstream to identify an extra chromosome or to determine ...

With the help of an AI tool, computed tomography (CT) scans taken originally to look for tumors or bleeding or infections, also revealed calcium buildup in arteries, a sign of worsening cardiovascular disease.   This is the result of a new study led by researchers at NYU Langone Health and an example of a new trend in “opportunistic screening,” wherein radiologists repurpose existing medical images to diagnose illnesses beyond what the scan was originally designed to find. Presented at the annual Radiological Society of North America ...

Nativity—characterized by place of birth, duration of residence in the host country, citizenship and immigration status—greatly influences the health of foreign-born individuals in the United States (U.S.). Despite this, many national health surveys omit questions about these dimensions of nativity, particularly immigration status. This omission limits the ability to assess health disparities across diverse immigrant subgroups and develop evidence-based policies and targeted interventions. To navigate this limitation, researchers rely on proxy measures or imputations ...

A team of researchers has beaten its own record for the fastest swimming soft robot, drawing inspiration from manta rays to improve their ability to control the robot’s movement in the water. “Two years ago, we demonstrated an aquatic soft robot that was able to reach average speeds of 3.74 body lengths per second,” says Jie Yin, corresponding author of a paper on the work and an associate professor of mechanical and aerospace engineering at North Carolina State University. “We have improved on that design. Our new soft robot is more energy efficient and reaches a speed of 6.8 body lengths per second. In addition, the previous model could only swim on the surface ...

A new long-term study that has documented the lives of a diverse sample of children over the past three decades shows that the majority of gun carriers began to carry in adulthood, not adolescence. These two groups — which the authors call “adult-onset carriers” if they began carrying after 21 years of age and “adolescent-onset carriers” if their carrying started prior to 21 years of age — have very different patterns in exposure to violence prior to carrying, persistence in carrying, and in actual gun usage. In “Dual Pathways of ...

"Dog is man's best friend" may be an ancient cliché, but when that friendship began is a longstanding question among scientists. A new study led by a University of Arizona researcher is one step closer to an answer on how Indigenous people in the Americas interacted with early dogs and wolves. The study, published today in the journal Science Advances and based on archaeological remains from Alaska, shows that people and the ancestors of today's dogs began forming close relationships as early as 12,000 years ago – ...

Around a third (32%) of people who grew up in Chicago have carried a concealed firearm on the city streets at least once by the time they turn 40 years old, according to a major study of gun usage taking in a quarter of a century of data. Urban sociologists behind the research argue that such carry rates are likely to be similar across many other major US cities.  The research suggests that almost half of men (48%) have carried a concealed gun by the age of 40, compared to just 16% of women.* The study, published in Science Advances, is one of the few to track gun usage in the same US population ...

People who are credulous are less capable of recognizing fake news, and along with mistrustful adults, are more susceptible to conspiracy thinking and vaccine hesitancy, according to a study published December 4, 2024, in the open-access journal PLOS Global Public Health by Michal Tanzer and colleagues from University College London, U.K. Epistemic trust is the readiness to regard knowledge communicated by others as significant, self-relevant, and generalizable to other contexts. Disruption to the capacity for epistemic trust may undermine healthy functioning that requires rapid, efficient checking and updating of social knowledge ...

Evolution is of the foundation of biology, but currently half of the United States population rejects the idea of human evolution. One of the most important factors in the acceptance of evolution ...

Higher emotional intelligence is linked to more emoji use with friends, while avoidant attachment is associated with less emoji use with friends and dating or romantic partners, according to a study published December 4, 2024, in the open-access journal PLOS ONE by Dr. Simon Dubé, Research Fellow at The Kinsey Institute, Indiana University, U.S., and colleagues. This pattern of results varies across genders and relationship types, with women using emojis with friends and family more frequently than men. Emojis are characters depicting emotions, objects, animals, and more. They can be sent ...

Scientists have uncovered the first direct evidence that ancient Americans relied primarily on mammoth and other large animals for food. Their research sheds new light on both the rapid expansion of humans throughout the Americas and the extinction of large ice age mammals. The study, featured on the Dec. 4 cover of the journal Science Advances, used stable isotope analysis to model the diet of the mother of an infant discovered at a 13,000-year-old Clovis burial site in Montana. Before this study, prehistoric diet was inferred by ...
