Spending too much time on screens may cause emotional and behavioral problems in children – and those problems can lead to even more screen use, according to research published by the American Psychological Association. Conducted by an international team of researchers, the study systematically reviewed and meta-analyzed 117 studies, encompassing data from over 292,000 children worldwide. The findings were published in the journal Psychological Bulletin. “Children are spending more and ...

Researchers from University of California San Diego School of Medicine have discovered that children living with multiple sclerosis (MS) show signs of accelerated biological aging, even in their teenage years. The research published online recently in Neurology®, the medical journal of the American Academy of Neurology, is the first to examine whether MS causes early aging in a pediatric population — offering new insight into the disease and its long-term progression. “We found evidence that children living with MS experience accelerated biological aging,” said ...

String theory has long been touted as physicists’ best candidate for describing the fundamental nature of the universe, with elementary particles and forces described as vibrations of tiny threads of energy. But in the early 21st century, it was realized that most of the versions of reality described by string theory’s equations cannot match up with observations of our own universe. In particular, conventional string theory’s predictions are incompatible with the observation of dark energy, which appears to be causing ...

Stopping the widespread use of unnecessary, potentially even harmful, cancer screenings can take up to 13 years and potentially even longer after new guidelines are put in place, according to a new study. Those unnecessary screenings open up patients to potential overdiagnosis, pain and excessive treatment, while costing more money and leading to anxiety and fear. “Excessive screening opens the door for a lot of negative consequences,” said Jennifer LeLaurin, Ph.D., an assistant professor of health outcomes and biomedical informatics at the University of Florida and lead author of the new study. “These ...

Depression and bipolar disorder of late onset may represent more than just mental health conditions. Growing evidence suggests these late-life mood disorders (LLMDs) could be not merely risk factors, but rather early warning signs of neurodegenerative diseases like dementia, even when they appear years before memory loss or other cognitive symptoms become apparent. Unfortunately, scientists have struggled to understand the connection between LLMDs and developing dementia at the biological level. While previous research suggested connections between specific disorders like late-life depression and Alzheimer’s disease, the specific neurological mechanisms involved remain mostly unclear. ...

LOS ANGELES — A new study led by Keck Medicine of USC researchers may have uncovered an effective combination therapy for glioblastoma, a brain tumor diagnosis with few available effective treatments. According to the National Brain Tumor Society, the average survival for patients diagnosed with glioblastoma is eight months. The study finds that using Tumor Treating Fields therapy (TTFields), which delivers targeted waves of electric fields directly into tumors to stop their growth and signal the body’s immune system to attack cancerous tumor cells, may extend survival among patients with glioblastoma, when combined with immunotherapy (pembrolizumab) ...

Antibiotics are supposed to wipe out bacteria, yet the drugs can sometimes hand microbes an unexpected advantage. A new study from Rutgers Health shows that ciprofloxacin, a staple treatment for urinary tract infections, throws Escherichia coli (E. coli) into an energy crisis that saves many cells from death and speeds the evolution of full‑blown resistance. “Antibiotics can actually change bacterial metabolism,” said Barry Li, a student at Rutgers New Jersey Medical School pursuing a dual doctoral degree for physician–scientists and the first author of the paper published in Nature Communications. “We wanted to see what those changes ...

Sexual harassment in online gaming is not an isolated phenomenon—it’s part of many players’ daily experience. According to the GamerVictim research project, led by the Miguel Hernández University of Elche (UMH) in Spain, one in five gamers has experienced sexual victimization in online gaming environments. The study also reveals that women, LGBTQIA+ individuals, and older players are the most affected groups across various forms of harassment. GamerVictim found that sexual victimization affects approximately 20% of a sample of over 1,800 Spanish gamers. Regarding hate-motivated incidents, such as insults based on race, gender, sexual orientation, ...

This year marks the opening of the United Nations Decade of Action for Cryospheric Sciences, an international initiative focused on the rapid changes occurring in glaciers, snow cover, ice sheets, sea ice, and permafrost and their impacts on the planet. MBARI’s cutting-edge research and technology will play a critical role in this effort, providing important data about the Arctic seafloor and the Southern Ocean. “Ice-covered ocean and land are integral to the health of our planet and host unique communities of life. The Decade of Action for Cryospheric ...

Ships operate in every ocean, and even the most remote waters aren’t off-limits. When they anchor, they leave behind a footprint. Anchoring cannot only disrupt marine life but also may damage undersea cables or pipelines, disrupt communication and cut off power supply. Yet, global ship activity and therefore anchoring is becoming more widespread, even in the most remote regions of the planet. Now, an international team of scientists has gathered the first video evidence of anchoring and chain damage in Antarctic waters. The team’s results are ...

Measles is on the rise in Canada and poses serious risks to pregnant people and their newborns, yet discussion about how to protect this vulnerable group is notably lacking. An article on measles and pregnancy by physicians working directly with measles outbreaks in Ontario summarizes key points for clinicians https://www.cmaj.ca/lookup/doi/10.1503/cmaj.250606. Measles in pregnancy increases the risk of infection with pneumonia, hepatitis, and even death, and increases the risk of miscarriage and premature birth. Intravenous immunoglobulin (IVIG) given up to six days after a measles exposure ...

Taking antipsychotic medications as prescribed lowers the risk of a car crash for drivers with schizophrenia, according to new research published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.250020. Schizophrenia can cause hallucinations and disorganized behaviour that affect the ability to safely operate a motor vehicle. Most people with schizophrenia are prescribed antipsychotic medications that improve many of these symptoms. Researchers hypothesized that these medications may also reduce the risk of a motor vehicle ...

Girls ages 7 to 18 use an average of six products for average cost of $168 per regimen As summer nears, authors caution only 26% of daytime skin care regimens contain sunscreen Videos ‘emphasize lighter, brighter skin’ and set a high standard of beauty CHICAGO --- It turns out when teens on TikTok say, “Get ready with me,” it can be more harmful than they might realize.  In the first peer-reviewed study to examine the potential risks and benefits of teen skin-care routines posted on social media, scientists at Northwestern Medicine found girls ages ...

New research shows that firms are more likely to break environmental rules when those who control the company finances are overly confident in their abilities. These environmental violations damage the company’s long-term performance, especially when it comes to credit ratings. However, the research, which looked at nearly 600 US companies over 17 years, found those in states with laws that require them to consider the interests of all stakeholders - not just shareholders - are better at avoiding these issues and protecting their financial health. The study was conducted by researchers at the University ...

What’s happening inside the brain of a passionate hockey fan during a big game? A new study from the University of Waterloo gives us a closer look at how the brain functions when watching sports, with data showing how different a die-hard fan’s experience is from that of a casual viewer. The researchers found that during offensive faceoff opportunities, fans deeply invested in hockey showed more activity in a part of the brain called the dorsal medial prefrontal cortex. This area is connected to emotional involvement and evaluative thinking — the mental ...

International regulation of tech giants, intellectual property reform, and preparation for workforce disruption must be prioritized by policymakers as artificial intelligence transforms society. These are the arguments of AI expert Professor Shalom Lappin, which he backs with comprehensive research in his new book Understanding the Artificial Intelligence Revolution. “The public domain and its citizens need to play a major role in determining the framework within which AI technology continues to develop,” argues Lappin, who holds positions at Queen Mary University of ...

About The Study: In this cohort study, state Medigap guaranteed issue protections were associated with higher rates of switching to traditional Medicare among Medicare Advantage beneficiaries newly diagnosed with cancer. These findings underscore the protective association of state Medigap regulations in facilitating a switch to traditional Medicare (especially among beneficiaries who likely desired more flexibility in accessing and receiving care) and illuminate potential disparities in switching that may reflect unequal abilities to compare and afford plans. Corresponding Author: To contact the corresponding author, Youngmin Kwon, PhD, ...

Tokyo, Japan – A team led by a researcher from Tokyo Metropolitan University has devised a new way of coating magnesium alloys to improve their corrosion resistance. Instead of costly, unwieldy, and slower coating techniques under vacuum, they used liquid-based chemical conversion coating with the addition of cavitation bubbles. The resulting thick coating helped improve corrosion resistance to chlorides and mechanical properties. The team’s new technology is aimed at reinforcing lightweight materials ...

PHILADELPHIA (June 4, 2025) - New research from the Monell Chemical Senses Center and Temple University about nutritional biomarkers using carbon and nitrogen stable isotope ratios showed very different results in children versus adults, which points the way to better understanding the role of added sugars in overall dietary patterns across the lifespan. Overall, added sugar intake by Americans well exceeds amounts recommended by the federal government. This is concerning because excess intake is associated with chronic diseases such as diabetes and obesity. ...

Miami, Fl. — Giant viruses play a role in the survival of single-celled marine organisms called protists. These include algae, amoeba, and flagellates, that form the base of ocean food webs. And since these protists form an important part of the food chain, these large DNA viruses are often responsible for various public health hazards, including harmful algal blooms.  A new study from scientists at the Rosenstiel School of Marine, Atmospheric and Earth Science may help unravel the many types of viruses present in our waterways and oceans. This knowledge could help local leaders better ...

With careful planning and a little luck, researchers found a surprising upside to hurricanes after a Category 4 storm disrupted their expedition off the coast of Mexico. The team was able to sample the ocean right after the storm passed and found that the storms churn the ocean so powerfully and deeply — up to thousands of meters — that nutrient-rich, cold water is brought to the surface. The resulting phytoplankton blooms — visible in satellite imagery taken from space — are a feast for bacteria, zooplankton, small fish, and filter-feeding animals such as shellfish ...

RIVERSIDE, Calif. -- A study led by biomedical scientists at the University of California, Riverside School of Medicine shows how a genetic mutation associated with Crohn’s disease can worsen iron deficiency and anemia — one of the most common complications experienced by patients with inflammatory bowel disease, or IBD. While IBD — a group of chronic inflammatory disorders that includes Crohn’s disease and ulcerative colitis — primarily affects the intestines, it can have effects beyond the gut. Iron deficient ...

Chagas disease is often called a silent killer because many people don’t realize they have it until complications from the infection kill them. Researchers at the University of Cincinnati are exploring ways to interrupt the lifecycle of the parasite behind the illness, offering hope of developing a cure. The disease is spread by parasites found in kissing bugs, which suck the blood of people when they are sleeping. The bugs typically bite victims around their faces, which gives them their ironically sweet-sounding name. The bugs transmit the internal parasites in their poop, which infects the bloodstream of human hosts through the bite wounds. The study was published ...
