Magnesium is an essential mineral for bone and heart health.The average adult needs 320 mg to 420 mg per day.Foods rich in magnesium include nuts, seeds, leafy greens and whole grains. Whether related to claims that it might improve sleep or help you poop, magnesium has received a lot of attention over the last few years. And for good reason. Magnesium is an important nutrient for your overall health, especially for your heart, muscles and nerves. Unfortunately, many people in the U.S. consume less than what’s recommended, even though it’s found naturally in foods like leafy greens, beans, legumes, whole…
Sex between Aedes aegypti mosquitoes lasts about 14 seconds.Credit: Jacopo Razzauti/The Rockefeller UniversityFemale mosquitoes that transmit dengue and other diseases are actually in charge during sex, according to a study1 that challenges the long-held view that they are passive participants.Mosquito blood meals reveal history of human infectionsLeslie Vosshall, a neurobiologist at the Rockefeller University in New York City, and her team were intrigued by the observation that male mosquitoes of the Aedes genus seem to pursue females constantly, yet females typically mate only once in their lifetimes. “The question was: how are the females able to say no?” Vosshall says.Using…
Credit: Peter Dazeley/Getty Images Cigarette butts may pose a risk to the health of smokers and nonsmokers alike by acting as genetic pools of microbial antibiotic resistance, researchers report. With estimated annual cigarette consumption reaching nine trillion this year, the findings suggest that discarded butts present both a major health and environmental issue. The study, in the Proceedings of the National Academy of Sciences, revealed that cigarette butts were significant reservoirs and amplifiers of antibiotic resistance genes, which can drive the emergence of drug-resistant pathogens. Discarded butts harbored significantly higher levels of antibiotic resistance genes and potential pathogens than either…
CAR T-cells attack cancer cell, 3D illustration. [Nemes Laszlo/Getty Images] Scientists at École Polytechnique Fédérale Lausanne (EPFL), and at UNIL-CHUV, University Hospital Lausanne (CHUV) and University of Lausanne (UNIL) have developed a computational method to create synthetic receptors that help engineered T cells respond more effectively to tumors. The team, headed by Patrick Barth, PhD, at EPFL and Caroline Arber, PhD, at UNIL-CHUV, developed a computational platform for designing synthetic protein receptors from scratch. These receptors, called T-SenSERs (tumor microenvironment-sensing switch receptors), are engineered to detect soluble signals found in tumors and convert them into co-stimulatory or cytokine-like signals that…
Long-chain PFAS are thought to be more likely to accumulate in the body and pose greater health risks than short ones. But it seems that the majority of PFAS blood serum content of people exposed to contaminated drinking water was composed of ultrashort-chain PFAS.Image credit:©iStock, narvikkPer- and polyfluoroalkyl substances (PFAS) are synthetic molecules found in a wide range of consumer products, from non-stick pans to stain-resistant carpets. They are often called “forever chemicals” due to their persistence in the environment as well as living organisms.People are typically exposed to PFAS when they consume food or water that has been contaminated…
6. Tea Tree OilTea tree oil has antimicrobial and anti-inflammatory properties that may make it suitable for treating psoriasis, although more studies are needed.[12]Shampoos and creams containing tea tree oil may help soothe scalp pain and irritation.[5]Be sure to do a patch test before trying this treatment, as tea tree oil allergies are not uncommon. Never apply undiluted tea tree oil directly to skin. Always dilute with a light “carrier” oil like avocado, argan, or jojoba, at a ratio of 1 part tea tree oil to 10 parts carrier oil.7. CapsaicinCapsaicin is the compound that makes chili peppers spicy. Over-the-counter…
Creatine fuels your brain, helping it recover from stress and stay sharp under pressure.It may boost mood, memory and focus, especially when you’re tired or sleep-deprived.Experts suggest 10 to 20 grams daily for brain energy—check with a provider before starting. When your phone’s battery runs low, you probably scramble to find a charger. But when your own ‘internal battery’ starts to feel drained, what do you do to recharge? Nutrition researchers presenting at the 2025 Food and Nutrition Conference and Expo (FNCE) say there’s one nutrient many of us could benefit from: creatine. Creatine isn’t a steroid or drug, and…
BiographySeth Berkley is a US physician and infectious disease epidemiologist trained at Brown and Harvard Universities. After completing residency in internal medicine in Boston he joined the Special Pathogens Branch of the US Centers for Disease Control and Prevention (CDC) and worked on vaccine and HIV/AIDS programmes in Uganda. He later led the Rockefeller Foundation’s vaccine work, founded the International AIDS Vaccine Initiative, and served as chief executive of Gavi, the Vaccine Alliance (2011-23). He co-created Covax (Covid-19 Vaccines Global Access) during the covid pandemic to ensure that vaccines reached all countries that needed them. He is now adjunct professor…
You can substitute tarragon with another one of your favorite dried herbs, such as oregano, rosemary, basil, marjoram or dill. It won’t have the same flavor, but for this soup recipe, it should work just fine. One thing to remember is that dried herbs are stronger than fresh, so if you opt for a more pungent dried herb, taste carefully to avoid adding too much.
