This provocative essay asks whether famous longevity spots reveal the secret to longevity or expose deeper flaws in the data behind modern nutrition and aging science. Essay: The Red Zone: The Real Color Behind the Blue Zone’s Geographic Longevity Myth. Evdiros village, Ikaria, Greece. Image credit: Lemonakis Antonis / Shutterstock In a recent essay published in a magazine public health magazineThe authors, Jairo Etcheverry of the National University of Colombia and Joachim P. Sturmberg of the University of Newcastle, Australia, critically analyze the “Blue Zone” (BZ) concept in parallel with Ancel Keys’ “lipid hypothesis.” Their critique largely challenges this concept,…

The feeding control study aims to answer one of the biggest questions in nutritional science: Is UPF harmful because of the way it is made or the ingredients it contains? Recent articles published in journals modern clinical trials We described a protocol for a randomized controlled trial (RCT) designed to investigate how the unique characteristics of ultra-processed foods (UPFs) influence cardiometabolic risk. UPF is becoming increasingly prevalent in diets around the world. Meta-analytic evidence suggests that high UPF intake is associated with increased cancer, cardiovascular disease (CVD), diabetes, and mortality. Despite increasing research on UPF, the characteristics underlying its negative…

A recent study examining women’s sexual responses to different types of written pornography found that individual attitudes, rather than evolutionary reproductive traits, best predicted arousal from offensive content. Women who reported prior exposure to violent sexual media and believed more strongly in conventional wisdom about sexual assault experienced higher arousal from nonconsensual stories. The study, published in the Journal of Sex Research, highlights how media consumption habits and social conditioning shape sexual preferences. Demand for erotica and romance novels is overwhelmingly driven by female readers. Genres that feature dark, forced, or violent themes are very popular in this market. In…

Two studies conducted in Canada found that subconscious memories of frustration with autonomy made people more likely to endorse, be angry about, and express a desire to spread false conspiracy theories. The study was published in the Journal of Personality. A conspiracy theory is the belief that important events or situations are secretly controlled by powerful groups acting in covert and harmful ways. They usually assume that official explanations are false or incomplete and that the real truth is being deliberately suppressed. People may develop conspiracy theories when they feel anxious, threatened, helpless, or unable to make sense of confusing…

Young people between the ages of 18 and 35, regardless of their political beliefs, tend to use moral and political arguments to shame others and assert superiority. This pattern suggests that hostile political expressions may be driven by an underlying desire for social status rather than loyalty to a particular party. The study was published in the journal Political Psychology. Political dialogue has become increasingly moralized in recent decades. People often frame standard policy disagreements as absolute moral obligations. This turns everyday debates into battles between perceptions of good and evil, creating a dynamic that deeply divides society. As political…

At the bottom of some mezcal bottles sits one of the most famous curiosities in the world of spirits. It’s a pale, curled-up “worm” preserved in alcohol. It’s helped give mezcal an air of mystery for decades, but scientists have now shown that this famous bottle stowaway isn’t a bug at all. Mezcal is a distilled spirit made from agave, the same plant group used to make tequila. Most bottles are sold without any additions, but a small number contain larvae known as gusanos de maguey (Spanish for agave worm). Although this tradition feels ancient, it’s actually much newer than…

Recent research published in Quarterly Political Survey Research shows evidence that public support for transgender women participating in women’s sports decreased significantly between 2019 and 2024. This shift suggests that it is related to political messages that position transgender women as a threat to female athletes, particularly influencing conservative voters. These findings highlight how laws originally designed to prevent discrimination can be reinterpreted to exclude newly visible minority groups. Political scientists James N. Druckmann and Elizabeth A. Shallow conducted this study to understand how societies decide who belongs to particular protected groups. In the United States, certain groups enjoy legal…

Each year, during Central America’s dry season (usually between December and April), strong northerly trade winds drive important oceanic processes in the Gulf of Panama. These winds push surface water, causing cold, nutrient-rich water from deep to rise toward the surface. This process, known as upwelling, plays a major role in the region’s marine life. This promotes productive fisheries, protects coral reefs from heat stress, and helps keep waters along Panama’s Pacific beaches cool during the busy “summer” holiday season. A 40-year pattern suddenly changed. Scientists at the Smithsonian Tropical Research Institute (STRI) have been tracking this seasonal upwelling for…

Researchers have found that plastic particles can get into wheat and tomato plants and inhibit their growth. The study recasts farm soil as part of the pathway by which plastics enter the food system.In silty loam soils, wheat and tomato roots grabbed large plastic particles and moved smaller plastic particles further down.Where does plastic end up? A team led by Dr Sima Giajalomi from Griffith University set out to investigate the movement of plastic particles in crops under farm-like conditions.The researchers documented how the plastic remained concentrated around the roots, while some of the smallest materials penetrated the…

Artificial intelligence systems tend to over-agree and validate users, even when they describe themselves as engaging in harmful or unethical behavior. People who interact with these highly likable chatbots become convinced that they are right and are less likely to apologize during interpersonal conflicts. The study, published in the journal Science, points out that millions of people are turning to technology for everyday advice, creating new social risks. As conversational software becomes more mainstream, users increasingly treat tools like digital therapists and advisors. Almost one-third of U.S. teens report that they rely on artificial intelligence instead of talking to a…
