One of the big mysteries in food allergy is why two people with similar levels of peanut specific antibodies can react so differently. It turns out the answer may be in the mouth and gut’s bacteria. A new study, led by researchers at McMaster University and published online in Cell Host & Microbe on March 3, 2026, shows for the first time how gut bacteria break down parts of an allergenic food and influence how a person reacts to peanuts. Peanut allergies are amongst the most common food allergies in Canada, ...

A team led by researchers at the University of Toronto has found an association between ultra-processed foods in early childhood, and behavioural and emotional development.  Specifically, the team found that higher ultra-processed food consumption is linked to behavioural and emotional difficulties including anxiety, fearfulness, aggression or hyperactivity. “The preschool years are critical for child development, and it’s also when children begin to establish dietary habits,” ...

When a new species is discovered, it’s tempting to imagine an adventure novel, said Chan Kin Onn of Michigan State University. “Most people have this image of an intrepid explorer braving an isolated mountain or some other remote place, and stumbling across a creature that no one has ever seen before,” Chan said. Sure, that still happens occasionally. “But most of the time it’s far less glamorous,” he added. Instead, the vast majority of new vertebrate species are “discovered” by revisiting known ...

In an elderly-care themed skit during the 2026 Spring Festival Gala (Chunwan), a lifelike android was modeled on actress CAI Ming. Why are humanoid robots becoming so lifelike and indistinguishable from real humans? One key technology enabling virtual humans to express vivid emotions, recognize identities, and demonstrate embodied intelligence is three-dimensional (3D) facial keypoint detection. However, due to the lack of large-scale, accurately annotated 3D facial datasets, most current 3D facial ...

SAN ANTONIO — March 3, 2026 — To meet increasing demands for carbon capture and storage (CCS) services, Southwest Research Institute (SwRI) has completed updates to its subsurface safety valve (SSSV) facilities to accommodate testing for CCS applications. CCS mitigates carbon dioxide (CO2) emissions by capturing CO2 from industrial or energy-related sources and transporting and storing the greenhouse gas safely underground to prevent release into the atmosphere. SSSVs are used in traditional oil and gas operations to serve ...

The beta cells in our pancreas act as highly sensitive sensors that constantly measure the amount of sugar in our blood. As soon as we eat something and the sugar level rises, the beta cells produce insulin to help the body process the sugar properly. This process requires an enormous amount of energy from the cells, which they generate in their own internal power stations, the mitochondria. Research now shows that iron is the crucial fuel that enables these power plants to function during cell growth. "During ...

As climate change nudges weather in the eastern Cascades in extreme and volatile directions, forest managers in the region have a lot to juggle. Hotter, drier summers are contributing to bigger and more frequent wildfires. Meanwhile, warmer winters may cause the Cascades to lose 50% of its annual snowpack over the next 70 years. Mountain snow supplies the Yakima River Basin with 75% of its water supply, making it a crucial reservoir for both nature and agriculture across a broad swath of central Washington. Less winter snow also leads to drier and more fire-prone forests in the summer. To encourage fire resilience, forest ...

Astronomers with the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX), have used data from the project to make the largest, most accurate 3D map yet of the light emitted by excited hydrogen in the early universe, 9 billion to 11 billion years ago. This specific form of light, called Lyman alpha, is emitted in large quantities when hydrogen atoms are exposed to a star’s energy. That makes it a great tool for finding bright galaxies in this far-off time, which experienced a rash of star creation. However, the locations of fainter galaxies and gas, which also emit Lyman alpha, have remained largely unknown. “Observing ...

Pre-teens who struggle to control their video gaming habits are more likely to have psychotic-like experiences a year later, a new study has found. McGill University researchers and colleagues at Maastricht University found that 12-year-olds who showed signs of problematic gaming were more likely to experience mild paranoia, unusual beliefs or disturbed perceptions at age 13. “Problematic gaming means having difficulty controlling one’s amount of gaming, leading to distress or problems at school or in relationships,” said ...

WASHINGTON, March 3, 2026 — When you reach the bottom of a container of milk or honey, you might be tempted to tip the container over to get that last pesky little bit out. After all, you only need another teaspoon for that recipe, and you’re sure it’s in there! In Physics of Fluids, by AIP Publishing, researchers from Brown University present two related studies about thin film fluid flows in the kitchen: one about the relationship between how long it takes to tip the remaining liquid out of a container and its viscosity, and the other about the ideal time to wait before dumping ...

WASHINGTON, March 3, 2026 — If you’re diagnosed with breast cancer, what should you eat to ensure the best prognosis? In APL Bioengineering, by AIP Publishing, a multidisciplinary team of researchers at Princeton University conducted a study to find out. “We took the approach of building identical engineered tumors and culturing them in conditions that mimic the blood composition of patients under different dietary states,” author Celeste M. Nelson said. “We were hoping to identify dietary conditions that would slow tumor growth. Instead, we found one dietary ...

About The Study: In this cohort study of preschoolers in Canada, higher ultraprocessed foods (UPF) intake was associated with adverse behavioral and emotional symptoms by age 5. These findings suggest that replacing UPF with minimally processed foods (MPF) during the preschool years may support healthier behavioral development, with potential benefits for long-term mental health. These findings also support ongoing policy actions that promote MPF and underscore the need for early-life dietary interventions.  Corresponding Author: To contact the corresponding author, Kozeta Miliku, MD, PhD, email kozeta.miliku@utoronto.ca.

There is a clear correlation between health professionals’ use of alcohol and drugs and how they perceive that their substance use affects their work. The more they use, the worse they believe they are at taking care of their patients. Asked 3300 professionals about their substance use The research is based on data from almost 3300 doctors and nurses in Sweden, who reported having a problematic relationship with alcohol and illegal drugs. The participants were asked about their use of alcohol, cannabis and psychostimulants, ...

Tiny life forms tucked into debris from an asteroid hit could catapult to other planets – including Earth – and survive, a new Johns Hopkins University study finds. The work demonstrates that a certain hardy bacterium easily withstands extreme pressure comparable to an ejection from Mars after an asteroid hit, as well as the inhospitable conditions it would face during the ensuing interplanetary journey. The study, published today in PNAS Nexus, suggests that microorganisms can survive remarkably more extreme conditions than expected, and raises questions about origins of life. The work ...

As members of the public increasingly turn to AI chatbots to understand their world, even subtle latent biases in the underlying models could affect public understanding of the present—and past. Daniel Karell and colleagues explored the effects of both unintentional and intentional political biases in LLMs by asking 1,912 research participants to read GPT-4o and Wikipedia summaries of two 20th century historical events: the 1919 Seattle General Strike and the 1968 Third World Liberation Front student ...

Children with prenatal opioid exposure face struggles in health, education, and social well-being throughout their childhoods and teenage years, even when sociodemographic factors are factored out. The global opioid crisis has largely been viewed as a crisis of adult users, but it has also led to a rise in children exposed to opioids before birth, only some of whom are diagnosed with neonatal abstinence syndrome—essentially, withdrawal. In 2023, approximately 95,000 American infants may have been exposed to opioids in utero. Gaëlle Simard-Duplain and Jonathan Zhang analyzed two decades of linked administrative data in British Columbia for 897,668 births ...
