Duke-NUS scientists have discovered that aging muscle may contribute to cancer growth by releasing fewer extracellular vesicles, tiny particles that cells use to communicate with one another. Their study also found that the composition of these particles changes with age, weakening protective signals that help suppress tumor development.
Exposure to a common plastic chemical before and shortly after birth may have lasting effects on behavior. Researchers found that male rats exposed early in life to DEHP—a plasticizer used in products ranging from medical devices to toys—showed significantly higher anxiety as adults, even long after exposure had ended. The animals were more hesitant to explore open spaces and spent more time frozen in place, classic signs of anxiety in rodents.
New research led by a scientist at IPAC—a science and data center for astrophysics and planetary science at Caltech—studying the hot Jupiter CoRoT-2 b has settled on one of the three leading hypotheses explaining why its atmosphere has a hot spot in the opposite direction from that seen on all other exoplanets of this type.
Career interest tests can be very helpful for teenagers and young adults deciding which career to pursue. New research from Michigan State University challenges the assumption that vocational interests are only relevant for early career decision-making; rather, they remain relevant into adulthood.
When moving around in their surroundings, humans heavily rely on what is known as proprioception, sometimes referred to as the "sixth sense." This is the body's subconscious ability to sense its own position, movements and location in space, via many tiny receptors that respond to mechanical strain located in the muscles, tendons and skin.
The Bundibugyo virus only emerged twice before. Now, scientists see a chance to get to know it better
Conduct problems—including persistent rule-breaking, aggression, irritability and difficulty following school rules—are associated with small but widespread differences in brain structure, according to a major international study of more than 14,000 children and adolescents, led by the University of Bath in the U.K.
UK newspapers responded to a major climate ruling by the world's top court by claiming "lawfare" and linking the decision to the U.K.'s proposed handover of the Chagos Islands to Mauritius, a new review of global media coverage has found. The review is titled Frames in Newspaper Coverage of the ICJ Advisory Opinion on Climate Change and Their Impact Potential.
A new paper led by researchers at the University of Victoria's Canadian Institute for Substance Use Research (CISUR) contributes to mounting evidence that alcohol use can cause pancreatic cancer.
Many animals exhibit fascinating collective behaviors, which allow them to move, search for food, reproduce and avoid threats more effectively than they would alone. One of these behaviors is queuing migration, which essentially entails traveling as a group in an organized line or procession.
Ancient hunter-gatherers may have contracted the pathogen from marmots
Researchers from Sun Yat-sen University and collaborating institutions have discovered a new species of bumblebee goby on Hengqin Island in Guangdong Province, marking the first recorded presence of this fish genus in China. The discovery and description of Brachygobius jennie, detailed in a published study in Zoosystematics and Evolution, expands the known geographical distribution of these small coastal fishes northeastward into the subtropical mangrove wetlands of the Zhujiang River Estuary.
A small clinical trial suggests that probiotics may offer a surprising mental health boost for older adults with depression. Seniors who took a daily probiotic alongside their regular antidepressant treatment experienced slightly greater improvements in depression and anxiety symptoms than those who received a placebo.
The rapid rise of GLP-1 medications such as semaglutide and tirzepatide has transformed obesity treatment. Still, experts say medications alone are not enough to address one of the nation's most pressing chronic diseases.
A study led by researchers at Children's Hospital of Philadelphia (CHOP) demonstrates a new method of using decellularized cartilage with patient-specific cells to help enlarge pediatric airways narrowed as a result of severe subglottic stenosis. Researchers demonstrate that this new method is faster, more effective and able to overcome issues associated with the current standard grafts, such as donor site morbidity, insufficient tissue volume and a delayed timeline. The findings are published in the journal Nature Communications.
Smartphone apps, fitness trackers and wearable devices help people with heart disease get more physical activity in their daily lives, according to an analysis of previous research published in the Journal of the American Heart Association.
Neutrinos are one of the fundamental particles of the universe. They live a ghostly existence with no electric charge, very little mass and extremely few interactions with matter. They are also the most abundant particles with mass in the universe and can be created through a variety of processes, such as the decay of heavy particles, nuclear reactions in the sun and the explosions of stars.
SpaceX shares surged again Tuesday, lifting Elon Musk's rocket company into the world's top five in market value for most of the session as a record-breaking IPO gave way to a torrid buying frenzy.
