Scientists have long believed that the recipe for producing queen bees is simple. By feeding the developing larvae with plenty of royal jelly, the queen bee becomes the ruler of the colony. New research suggests the reality is much more complex. The researchers discovered that future queen bees are raised in specially designed nurseries created by young worker bees. These chambers provide unique wax, a warm environment, and dedicated care to help the larvae develop into healthy queens. The survey results were published in a magazine natureshowing that the structure known as the queen cell, also known as the “royal…

According to a major review, AI can help clinicians work faster and more accurately, but only if the system is built around real-world clinical workflows, coordinated trust, and clear accountability. Research: Human-AI collaboration in healthcare: A scoping review. SWK Stock / Shutterstock New scoping review available as journal article npj digital medicine We discuss recent evidence regarding the utility of human-artificial intelligence (AI) collaboration in healthcare. background Applications of artificial intelligence (AI) in healthcare are rapidly increasing across clinical tasks such as medical documentation, triage and task prioritization, image interpretation, and care coordination. However, in medical settings that involve important…

Many people in the UK who are considered to be at high risk of vitamin D deficiency may not be getting enough nutrients throughout the year, according to new research. The findings cast doubt on the widely held belief that simply spending time in the summer sun can restore healthy vitamin D levels. Researchers from Newcastle University’s Human Nutrition and Exercise Research Center analyzed vitamin D levels in around 300 people across the north of England. Their results suggest that a significant number of people may be vitamin D deficient year-round without realizing it, which can impact bone health, overall…

Exercise may have a modest but measurable protective effect against weight gain after dieting or bariatric surgery, but the evidence is less clear as to whether it significantly reduces fat mass. Research: Effects of exercise interventions on weight regain after weight loss: A systematic review and meta-analysis.

New health screening data from South Korea suggest that while antidiabetic treatment administered promptly after the threshold for type 2 diabetes is crossed may improve survival rates, cardiovascular benefits remain promising but unproven. Study: Timing of antidiabetic drug initiation and risk of cardiovascular events and death. Image credit: Anastasiya Artcomma / Shutterstock In a recent study published in the journal JAMA network openresearchers investigated the association between the timing of antidiabetic drug (ADM) initiation and the risk of major major cardiovascular events (MACE) and death in people who newly reach laboratory diagnostic thresholds for type 2 diabetes (T2D). T2D is…

Most pandemics begin when a virus or other pathogen is transmitted from animals to humans. Many scientists believe this is how COVID-19 emerged. SARS-CoV-2, the virus that causes the disease, is closely related to coronaviruses found in bats. Now, a team of researchers from the UCSF Institute for Quantitative Biosciences (QBI), the Icahn School of Medicine at Mount Sinai, the Pasteur Institute, and the Fred Hutchinson Cancer Center has identified surprisingly small genetic differences that may help explain how some animal viruses adapt to and cause serious disease in humans. Their findings were; Cell hosts and microorganismshave shown that changing…

The 2026 International Plastic Pellet Count shows that tiny plastic beads are polluting waterways around the world.More than 1 million so-called “nurdles” have been identified, including more than 15,000 across California, according to a report released Tuesday.”We’re doing the tally as a way to show that this is a real problem,” Jen Engstrom said. “Because it’s transparent, it easily blends into the sand along the beach, so you often don’t even know it’s there.”Mr. Engstrom directs the CALPIRG Education Fund, which participated in the count.In May, more than 1,000 volunteers combed sites around railways, beaches and other waterways in six…

Season-long studies of teenage soccer players provide reassurance about short-term brain health, but elevated preseason biomarkers show why the heading debate is far from settled. Research: Youth soccer participation and its impact on brain health in youth athletes. Image credit: Master1305 / Shutterstock In a recent study published in JAMA network openresearchers conducted a longitudinal study to determine how competitive youth soccer, specifically heading the soccer ball, is associated with brain health outcomes in the developing brain. The study followed 129 male athletes over one season and assessed the participants’ cognitive performance, behavior, balance, and neuroimaging metrics. Encouragingly, the study…

The group’s biggest concern is how the Environmental Protection Agency is acting. Key climate, water and pollution regulations weakened Since President Donald Trump returned to power. “I don’t want to stick my head in the sand and ignore the world burning,” Diggins said in an…

Deaths related to air pollution have fallen by an estimated 40% in London in the five years since 2019, according to new analysis.The city’s mayor, Sadiq Khan, welcomed “overwhelming evidence” that ultra-low emission zones save lives.The figures come from a study by Imperial College London, which found that toxic air pollution in London had fallen significantly, with nitrogen dioxide levels falling by 41% and particulate pollution by 28%.Imperial researchers said the latest scientific evidence shows air pollution has a greater impact on health than previously recognized, with previous estimates putting air pollution at risk for 4,000 premature deaths in 2019.This…
