As an avid home cook and former pro baker, I’ve always looked at onions as a flavor builder more than anything else. They’re the foundation of many recipes, and they can even improve your health, according to researchers. When you eat them regularly, onions can potentially support your digestive, heart and eye health. Onions also naturally possess antibacterial properties, and they may be able to lower your cancer risk..  All of that for a root vegetable? Yes. But, they’re only as good as they are fresh. A spoiled onion is one that’s overly sprouted, soft, dry or moldy, and it’s…

Shorter storage durations of donor human milk may reduce gastrointestinal complications in premature infants, including necrotizing enterocolitis, according to new research. Minimizing milk storage time may help preserve protective properties that are critical for preterm gut health.The researchers believe their findings may necessitate updated WHO and CDC guidance, as both currently advise that frozen milk can be stored safely for up to a year for all babies. “Our results showed that babies weren’t as protected with the use of donor milk that was stored for a longer time as with donor milk that was stored for shorter periods of time,”…

High blood pressure is a common condition that has both genetic and lifestyle components.Limiting sodium is integral to managing blood pressure, including sodium in ultra-processed foods.Physical activity and managing stressors are other habits that influence blood pressure. If you’re one of the 120 million American adults with high blood pressure, there are numerous steps you can take to lower it, including reducing the amount of salt you eat. “Sodium is a major preventable driver of blood pressure variation,” says David L. Katz, M.D. a specialist in internal and preventive medicine with expertise in nutrition. But there’s more to reducing sodium…

How Not to Die (Too Soon)Devi Sridhar Viking (2025)Public health is often a contested subject. Devi Sridhar, a US–UK health scholar of Indian origin, is acutely aware of its complexities — and of just how much our health depends on national policies. In her excellent book, she tackles topics such as exercise, diet, guns, mental health and air pollution. She notes that, in low-income countries, physical activity, associated with poverty and labour, was abandoned as people became richer. But in wealthy countries, gymnastics, for example, has become linked with high socio-economic status.Good VibrationsStefan Koelsch Cambridge Univ. Press (2025)Music is “a…

The contribution of genetics to the variability in people’s metabolism has remained largely unknown. This is, in part, because genetic studies of human metabolism have been limited in scale and allelic breadth. Now, the largest genetic map of human metabolism has been created, revealing new insights on the role of metabolites in health and disease and creating a blueprint for further research. This work is published in Nature Genetics in the paper, “A genetic map of human metabolism across the allele frequency spectrum.” The team used data from ~450,000 individuals through the UK Biobank. The authors examined the consequences of…

Researchers used a new spatial proteomic method to map protein localization changes during viral infection.Image credit:© iStock, sasha85ruJust like workers need the right environment to efficiently perform their tasks, proteins require placement within specific cellular compartments to function properly. Therefore, understanding where proteins reside within a cell is crucial for unraveling their roles in health and disease. Scientists from the Chan Zuckerberg Biohub, including mass spectrometry platform leader Josh Elias, developed a new mass spectrometry-based method to map proteins’ spatial organization within cells.1 After attaching molecular tags to proteins that resided in distinct subcellular spaces, whole organelle immunoprecipitation allowed them…

October has arrived, Libra season is well underway, and with it, we have an Aries full moon on the horizon. Not only that, but it’s going to be a super moon, appearing relatively bigger and brighter in the sky. And as the closest full moon to the autumn equinox, this is the annual Harvest Moon, as well as October’s Hunter’s Moon.

Colon cancer is on the rise, but many risk factors for it are modifiable, including diet. A new study connects foods rich in beta-carotene with a 40% lower risk of colorectal cancer.These foods include carrots, sweet potatoes, pumpkin, spinach, mangoes and cantaloupe. When it comes to colorectal cancer (CRC)—cancers of the colon and rectum—we’re constantly learning more about risk reduction from new research. For example, some recent studies have suggested a diet high in processed and red meat increases your risk, but a high-fiber diet can help reduce it. There is also evidence that dairy—including probiotic-rich yogurt—may help reduce your risk…

Judith R HarrisonNewcastle upon Tynejudith.harrison{at}newcastle.ac.ukCredit: Wellcome CollectionDavid Enoch was a doctor who made ministers flinch. “I was a troublemaker,” he recalled decades later, “But it was the only way to get changes made.” It was in 1965, when he took a consultant psychiatry post at Shelton Hospital in Shrewsbury, that he was first exposed to the geriatric wards hidden from public view. Here he introduced regular teaching and therapeutic communities—a democratic, participative group approach—and piloted one of Britain’s first care in the community schemes. He identified a core of progressive psychiatrists in other parts of the country, and they exchanged ideas.Enoch…
