A new autopsy just confirmed the first U.S. death from tick-borne alpha-gal syndrome.Alpha-gal syndrome causes delayed allergic reactions to mammal meat, dairy and some medicines after tick bites.Symptoms can lessen with strict diet changes; experts urge testing for those with unexplained post-meat illness. This week, the cause of a 47-year-old airline pilot’s death, which was once a mystery, was revealed. The autopsy results were published in The Journal of Allergy and Clinical Immunology, and they indicated that the New Jersey man had died from alpha-gal syndrome, a meat allergy developed by a tick bite. This is the first reported death…

One of the most important factors to consider before buying a new pair of walking or running shoes is their level of arch support. It’s a feature podiatrists constantly talk about, as “proper arch support is important for providing stability and alignment, which will help support your body from the ground up,” said Dr. Janine Ferrigno-Taddeo, DPM, podiatrist and vice president of Millburn Podiatry Group, PC, in a previous EatingWell article.  This is especially true if you have conditions such as plantar fasciitis, chronic foot pain or fat pad atrophy, although this list could go on. Oftentimes, however, shoes that…

The move ended US participation in what the White House described as “international agreements and initiatives that do not reflect our country’s values”. It marked a sharp break from decades of US leadership in the IPCC, where US scientists and diplomats have helped steer negotiations, shape reports and fund the process that underpins global climate action.Nature Index 2025…

It represents a historic inflection point in biomedical research. For decades, the scientific community has acknowledged the limitations of animal testing: it is expensive, slow, and often poorly predictive of human outcomes. Yet progress toward replacing animal studies with innovative, human-relevant approaches has been incremental, hindered by fragmented standards, a lack of validation pathways, and limited regulatory acceptance. ORIVA has the potential to change that. By establishing a…

Tailored vitamin D3 supplementation for heart attack patients may halve their risk of a second heart attack, according to new clinical findings. Researchers at the Intermountain Health non-profit healthcare system in Salt Lake City, US, led the large, randomized trial that monitored patients’ vitamin D blood levels and optimized their vitamin D3 dosing accordingly.Lead investigator of the study Heidi May, Ph.D., a cardiovascular epidemiologist at Intermountain Health, says the results are promising for “target to treat” dietary interventions.“We observed no adverse outcomes when giving patients higher doses of vitamin D3 supplementation,” she adds. “We’re excited with these results but know…

Marie Antoinette’s hair allegedly turned white overnight, just before her execution. Many later suggested that this account was likely exaggerated—her hair probably grayed gradually due to the stressful living conditions behind bars. For centuries after that, many people have observed that stress seemed to make their hair as well as others’ go gray. However, scientists didn’t uncover the biological mechanisms that underlie this process until recently. Fight-or-Flight Hormone Drives Irreversible, Stress-Induced Hair Graying in MiceIn a 2020 study, a team led by Ya-Chieh Hsu, a stem cell biologist at Harvard University, discovered that in mice, stress—whether it was physical or…

A new drive to tackle “rampant levels of bullying and harassment” experienced by ethnic minority staff in the health service has been launched by the NHS Race and Health Observatory.As part of a 16 month programme, researchers from the universities of Birmingham and Sheffield and the National Institute for Health and Care Research’s Yorkshire and Humber Patient Safety Research Collaboration will use a mixed method study to analyse NHS staff survey data and produce recommendations for resources to close the “ethnicity gap in bullying, harassment and abuse.”The announcement follows a recent open letter to The BMJ from doctors and healthcare…

Credit: Avalon_Studio / Getty Images Researchers at Dartmouth Hitchcock Medical Center have developed a new test that could diagnose Lyme disease earlier and more accurately than currently available testing methods. Results presented today at the Association for Molecular Pathology (AMP) 2025 Annual Meeting & Expo show this new test achieved 90.9% sensitivity in a small set of samples. This represents a major improvement when compared to two-tiered serology testing, the current diagnostic standard for Lyme disease, which typically has a sensitivity lower than 50% during early stages, leading to many false negative results in the first six weeks of infection. …
