A team led by researchers at the University of Toronto has found a link between ultra-processed foods and behavioral and emotional development in early childhood. Specifically, the research team found that high intakes of ultra-processed foods are associated with behavioral and emotional difficulties such as anxiety, fear, aggression, and hyperactivity. Preschool is a critical period for a child’s development and is also the time when children begin to establish eating habits. ” Kozeta Milik, principal investigator of the study and assistant professor of nutritional sciences, Faculty of Medicine, Temerty University “Our findings highlight the need for early intervention, including professional…

A short-term spike in air pollution in New Jersey due to the 2023 Canadian wildfires is associated with higher stroke rates and more severe strokes, according to a preliminary study published March 3, 2026, which will be presented at the American Academy of Neurology’s 78th Annual Meeting, April 18-22, 2026, in Chicago and online. Wildfire smoke contains pollutants such as ozone and particulate matter, making it not only a nuisance but also a potential public health hazard. The 2023 Canadian wildfires caused unprecedented air quality declines across the northeastern United States. Our findings show that short-term exposure to increased…

science news from research institutions The super-tough microorganisms can withstand Mars-level impact forces, suggesting the possibility that life can jump from planet to planet. Date: March 3, 2026 Source: PNAS Nexus Abstract: Bacteria, famously resilient, may be strong enough to survive one of the most violent events possible on Mars. In a laboratory experiment designed to mimic the impact of a large asteroid impact, researchers forced Deinococcus radiodurans between steel plates and sprayed it with pressures reaching 3 GPa (30,000 times atmospheric pressure). Even under these extreme conditions, the majority of microorganisms survived. Share: Full text By simulating the impact…

Hundreds of cancer diagnoses and deaths could be prevented if Canadian jurisdictions required alcohol warning labels and minimum pricing based on the number of standard drinks in a container, according to a new study led by the Canadian Institute for Substance Use Research (CISUR) at the University of Victoria. This study lancet public healthset out to see how different alcohol policy scenarios could reduce the number of alcohol-related cancers in Canada. The researchers considered five scenarios. Two are minimum price settings (also known as minimum unit pricing) associated with standard drinks in a container, with standard per-drink prices set at…

For people living with human immunodeficiency virus (HIV), lifesaving antiretroviral therapy prevents HIV-infected immune cells from making new copies of the virus, preventing disease and transmission. Historically, these infected cells were known as “latent” HIV reservoirs, meaning that the HIV within the infected cells was completely inactive. However, the idea that the entire HIV reservoir is latent is actually a misleading explanation, as some of the HIV reservoirs may still be highly active. Even though antiretroviral therapy prevents the production of a full-fledged HIV virus, some infected cells continue to vomit viral products. ” Dr. Nadia Lone, Senior…

A large observational study published in an open access journal suggests that getting seven hours and 18 minutes of sleep each night may be optimal for avoiding the risk of insulin resistance, a precursor to type 2 diabetes. BMJ Open Diabetes Research and Care. However, research shows that for people who sleep above optimal thresholds each night, weekend catch-up sleep increases the risk of impaired glucose metabolism. Researchers note that previously published studies have shown that sleep duration is strongly associated with the risk of insulin resistance, diabetes, and related metabolic disorders. But it’s not entirely clear what role, if…

For many years, treating periodontal disease involved scraping away plaque, removing damaged tissue, and using antibiotics that indiscriminately kill bacteria. New treatments can regenerate lost tissue, but doctors still don’t have a precise way to stop the infection without compromising the mouth’s healthy microbiome. A new study from the University of Florida College of Dentistry brings a breakthrough. Researchers have discovered that the main bacteria that cause periodontal disease have an internal “genetic brake” that controls their aggressiveness. By locking this brake in place, future treatments may be able to silence pathogens without touching beneficial bacteria. The study, led by…

Researchers at Duke-NUS School of Medicine have discovered a molecular “switch” that determines whether pancreatic cancer cells respond to or resist chemotherapy. The discovery points to a potential way to shift some of the most treatment-resistant tumors to a state where existing drugs can work more effectively. This study clinical research journalLet’s explain how this switch works at a molecular level. The results suggest that combining targeted therapy with standard chemotherapy may improve outcomes for patients whose tumors no longer respond to treatment. Why pancreatic cancer is so difficult to treat Pancreatic cancer is one of the deadliest cancers worldwide.…

A new study sheds light on the tense relationship between wolves and cougars in Yellowstone National Park. Researchers have found that many cougar encounters begin with wolves taking over prey that the cougar has already killed. To reduce these dangerous encounters, cougars can adapt by targeting smaller animals and avoid crossing paths with wolf packs. The study was conducted as wolf and cougar territories increasingly overlap in the western United States. Wolves have sometimes been responsible for killing cougars, but scientists have found no evidence that cougars have killed wolves. How cougars avoid encounters with wolves The study also found…

Scientists have discovered tiny new fossils, including: purgatoryby far the oldest known relative of all primates, including humans, living in the southern part of North America. The discovery provides new insight into how primates first evolved and spread across continents.The origin and early geographical history of primates has long caused debate among researchers. purgatoryIt is a small mammal, about the size of a shrew, that appears in the fossil record shortly after the dinosaurs went extinct about 65.9 million years ago. It is widely considered to be the oldest paleoprimate.Although rock formations from this era have been found throughout North…
