Microplastics are seemingly everywhere, including our food and kitchen gear. With so many culprits, I find it’s not worth it to try and strip plastic from your entire life—I would drive myself to a bad place if I did that. But I do strive to remove it from my routine when I can do so easily. Two of the main things I’ve ditched in the kitchen are plastic food storage containers and, more recently, plastic cutting boards. According to this 2024 study, 1 square millimeter of scratched plastic cutting board can release 3,000 microplastics, a staggering stat that spurred me…
Sponsored content brought to you by Upstream process intensification using perfusion cell culture has become a necessity for meeting today’s demand in monoclonal antibodies (mAbs) bioprocessing. By sustaining higher viable cell densities, extending culture duration, and enabling continuous product harvest, perfusion cell culture allows manufacturers to increase volumetric productivity while reducing cost of goods. The demand for scalable production technologies continues to rise as mAbs now account for roughly 60% of biopharmaceutical revenue, with most new approvals aimed at oncology and autoimmune diseases. Successful scale-up of perfusion cell culture to commercial manufacturing depends on developing a robust, well-characterized process at…
Credit: 3D rendering of human cell. anusorn nakdee / iStock / Getty Images Plus When the immune system responds to infection or injury, inflammation acts as a defense mechanism—but that same response must be tightly controlled. Regulatory T cells, or Tregs, are the immune system’s internal “braking” mechanism, turning off inflammation when the threat is neutralized. In new work from St. Jude Children’s Research Hospital published in Science Immunology, scientists describe how Treg cells use internal metabolic signaling to decide when to act and when to rest. “We discovered how regulatory T cells are activated and become more immunosuppressive during inflammation,”…
When people shift their daily routines by an hour, they create a mismatch between their social lives and their internal clock.Image credit:©iStock.com, solidcoloursAs countries around the world begin to turn their clocks back an hour, some people may rejoice at the extra time in bed while others might mourn the loss of evening light. For many sleep and circadian rhythm biologists, the end of daylight saving time is an overall positive thing. In fact, many groups, including the Society for Research on Biological Rhythms, have petitioned governments to adopt permanent standard time to improve public health.Kevin Koronowski studies how circadian…
Set to launch in November, each gummy contains 1,800mg of creatine monohydrate. Each serving consists of three gummies amounting to a total of 5,400mg creatine monohydrate. A daily dosage of three to five grams has been reported to be effective for improving muscle mass and performance. Marketed under the name Hi-Creatine Bites, the gummies, which come in Hakuto Peach Flavour will be sold on the brand’s website and selected gyms in Singapore in November. This is Foo’s second business venture in the supplements space, building on his experience in the anti-hangover space through DrinkAid set up with co-founder Solomon Poon…
New research reveals that daily supplementation with 740 mg of Euromed’s high-polyphenol pomegranate extract Pomanox leads to a small but statistically significant boost in insulin-like growth factor-1 (IGF-1) for older adults. IGF-1 supports normal cell growth and repair, and typically declines with age. Pomanox is a patented, high-polyphenol pomegranate extract suitable for cardiovascular, cognitive, metabolic, skin, and healthy aging applications. It is standardized to 30% punicalagins, which are polyphenols typically found in pomegranates.“In older adults, restoring IGF-1 toward mid-physiological levels is associated with better muscle function, metabolic health, and vascular integrity, which are all key to longevity and healthy aging,”…
Dietitians recommend black beans as a top carb for supporting healthy cholesterol.They’re rich in fiber, plant-based protein, resistant starches and phytochemicals, which help to lower total cholesterol.Black beans are affordable, versatile and convenient, making them easy to add to a variety of dishes. Think all carbs are bad? Think again. Despite their undeserved reputation as being “unhealthy,” the right carbs are highly nutritious and can even support heart health. “Carbs provide energy and key nutrients like fiber, vitamins and minerals,” says Lauren Manaker, M.S., RDN, LD, CLEC. When choosing carbs, complex options rich in fiber—like whole grains, legumes, fruits and…
Elgan Manton-Roseblade, medical student121The University of Edinburgh, Edinburgh, UK2UK Medical Students Committee, BMACorrespondence to: E Manton-Roseblade e.mantonroseblade{at}outlook.comIn 2024, only 70.8% of the 50 023 NHS medical staff who were surveyed felt confident raising patient safety concerns.1 The same year, the BMA found that an increasing number of doctors were staying silent for fear of retribution.2Improving the culture of speaking up is a priority for the NHS,3 but often the problem doesn’t start in the health service—but at medical school. A decade ago, the Freedom to Speak Up report called for a culture of safety to be fostered in educational settings.4 For…
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…
