Healthcare in low and middle income countries in Africa and elsewhere is being “hijacked” by commercial surrogacy companies, experts have warned.At a session at the European women’s rights conference FiLia in Brighton on 12 October, former surrogates and women’s rights campaigners from France, the US, and Germany argued that pregnancy complications such as sepsis, postpartum haemorrhage, and pre-eclampsia are higher in surrogate pregnancies and that the industry is distorting healthcare provision in commercial surrogacy destinations.Marie Josephe Devilliers, president of the feminist organisation International Coalition Against Surrogate Motherhood, presented evidence of such practice in Uganda, where a medical sector has been…
Both conditions can cause the same distressing symptom: swelling (angioedema).In both HAE and allergic angioedema, swelling can occur in the following parts of your face and body:[3][4]EyelidsLipsTongueThroat and airwaysHandsFeetGenitals“There are a few key differences in how the conditions present,” says Timothy Craig, DO, a professor of medicine and an allergy and immunology researcher at Penn State Health in Hershey, Pennsylvania.Histamine-mediated (or allergic) angioedema often causes redness, itchiness, and sometimes hives, Dr. Craig says.Although swelling related to HAE can look red, it’s typically not itchy, rarely has hives, and lasts longer — a few days rather than hours, he says.Both types of…

Their findings, published in the journal Science, detail how certain small molecules disrupt the interaction between the RAS protein and PI3Kα, providing a new pathway for treating RAS-driven tumors and HER2-positive cancers, without adverse effects. “Given the RAS gene is mutated across a wide range of cancers, we’ve been exploring how to stop it interacting…
Health claims are one of the most effective ways that dietary supplement companies can convey the benefits of their products. However, there are strict laws when it comes to health claims, and widespread confusion around how and when these laws come into play.Writing in the journal Nutraceuticals, Spanish food regulatory experts described the regulation of dietary supplements as “one of the most complex topics in food law,” with health claims cited as one of the most misunderstood areas.Health claims were unregulated in Europe until 2007 when the European Commission introduced a legal framework known as the Health and Nutrition Claims…
The sensing principle of these sensors is straightforward: the molecular target or drug to be monitored (shown in green in the illustration above) can interact with a specific DNA molecule, called aptamer (yellow molecule). Upon binding to the molecular target, this “aptamer” DNA can no longer inhibits another electro-active DNA (red DNA), that can then reach the surface of an electrode and generate an electrochemical current easily detectable with an inexpensive reader. [Jianbin Zhou] Drawing inspiration from natural cell signaling cascades, chemists at Université de Montréal (UdeM) have developed a DNA-based signaling cascade that allows them to quantify and report…
After 5 p.m., get your body moving, spend quality time with others and give your mind a chance to relax.Relieving stress lowers the body’s stress response, supports sleep and boosts both physical and mental well-being.Limit screen time, soak up morning light and enjoy a nutrient-dense diet to further strengthen mental health. Once the workday ends, most of us finally get a moment to breathe. But instead of truly decompressing, it’s easy to slip into habits that don’t actually restore our mental health—like doomscrolling, answering “just one more” email or zoning out in front of the TV. Experts say the hours…
“Brain food” is undergoing a transformation as a wave of new science-backed ingredient innovations unlocks new tiers of formulation for mental well-being. Experts highlight that new offerings are looking to take brain health claims beyond traditional pills and pharmaceuticals, with the introduction of anxiety-modulating prebiotics and a new class of ingredients for neurodevelopmental disorders, dubbed “psychobiotics.” Nutrition Insight speaks to industry experts at FrieslandCampina Ingredients, AB-Biotics, Balchem, and Gencor, who share insights on the latest innovations in functional ingredients for cognitive performance and mood balance.“We’re seeing some fascinating shifts in consumer behavior around the world in the brain health space.…
The black and white plumage coloration in different species of the wheatear songbirds is linked to multiple genetic variations near a single gene.Image credit:©iStock, Kenan TalasBirds have a dazzling display of patterns, from muted colors to vivid and striking hues. For a long time, scientists believed that the evolution of these traits was a slow process that took place when mutations gradually accumulated. But recent studies have shown that reshuffling of already existing genetic variation, either within a species or through hybridization between species, could produce these traits faster.1,2However, the exact interplay between this genetic reshuffling and the evolutionary history…
