Chronic inflammation often develops silently, without obvious pain or noticeable symptoms. But over time, it can lead to serious health problems such as type 2 diabetes, heart disease, obesity, arthritis, and even cancer. In the body, this process is driven by immune cells that release chemical signals to respond to injury or infection. What people eat can affect this activity. Many common foods and seasonings, such as herbs, spices, and aromatic plants, contain natural compounds known as phytochemicals that can influence inflammatory pathways. These ingredients have been combined in traditional diets and herbal remedies for centuries, long before their biological…
Microplastics have now been detected in human bile, and new research reveals how these tiny particles can interfere with cell function and potentially contribute to cholelithiasis. Research: Microplastics accumulate in human bile and accelerate cholangiocyte aging. Image credit: RHJPhtotos/Shutterstock.com recent Environmental science and ecotechnology In this study, we investigated microplastic accumulation and chronic toxic effects on the human biliary system. We also investigated the potential for in vitro therapeutic intervention against microplastic-induced cell damage using an experimental model. Microplastics as a new pollutant Plastics are highly valued in manufacturing for their durability, affordability, and corrosion resistance. However, these same properties…
BOGOTA, Colombia (AP) — Iran is has exposed deep vulnerabilities in the global economy. It’s not just our dependence on oil, gas and coal for fuel, but also on petrochemicals that underpin everything from food production to plastic packaging.As confusion spreads, energy marketthis war highlights how fossil fuels are embedded far beyond transportation and electricity. In the short term, increased dependence on petrochemicals will lead to higher prices for a myriad of products, while in the long term the pollution caused by petrochemicals will exacerbate climate change. A two-week ceasefire announced late Tuesday is a sign of hope that the…
Human DNA is constructed from long three-letter sequences of four nucleotides. These units, known as codons, tell cells which amino acids to use when building proteins. Although several different codons can code for the same amino acid, this is often considered simple redundancy in genetic systems. However, research is increasingly revealing that these so-called synonymous codons are not truly equivalent. Some codons make the mRNA molecule more stable, making it easier for cells to translate it into protein and increasing its efficiency. Others that are considered suboptimal are more likely to be translated weakly and broken down. Until now, scientists…
“I can’t eat just one Beccha!” This slogan for Lay’s Potato Chips was appealing in mid-20th century America, before the obesity epidemic. Looking back today, critics argue, it foresaw the food industry developing enticing products designed to make us overeat. The idea is that certain combinations of sugar, salt, and fat make manufactured foods not only delicious but also overly comforting, or what some nutrition experts call “hyperpalatable.” These ultra-processed foods, enriched with chemical additives, can reach a “bliss point” that causes cravings and impulsive eating. In today’s food environment, many of us succumb to these temptations at the expense…
Scottish farmers in the 1980s pioneered the practice of spraying wheat with glyphosate just before harvest. Struggling to dry crops evenly in the humid valleys, they came up with the idea of speeding up the process by killing the crops a week or two before harvest.Glyphosate, a revolutionary herbicide at the time that killed everything of plant origin and saved animal life, seemed perfect for the job. Soon, this practice spread to wet and cold agricultural regions around the world.Four decades later, thousands of tonnes of glyphosate are now being sprayed every year on UK farmland, as well as council…
WASHINGTON (AP) — Before Donald Trump returned to the White House, the Biden administration and many utility companies were building a renewable energy-driven future. They aimed to replace coal, reduce greenhouse gases and reduce air pollution, which kills more than 1,000 people a year.Dozens of coal-fired power plants emit as much global warming pollution as 27 million cars and were expected to be phased out during President Trump’s second term. Now, there may not be any more coal-fired power plants shutting down. After President Trump leaves officeAccording to officials and energy analysis firm Enbels.The United States is undergoing a dramatic…
Contamination with per- and polyfluoroalkyl substances (PFAS) is widespread in groundwater, surface water, and even drinking water, impacting millions of people around the world. Flinders University researchers have developed a promising new approach that could help remove some of the most elusive forms of these long-lasting pollutants from water. New method targets hard-to-remove PFAS A team led by Flinders ARC researcher Dr Witold Block has created a special material known as a sorbent that can effectively capture PFAS. Their method is particularly successful in capturing short-chain PFAS, which are notoriously difficult to remove with current water treatment technologies. Their findings…
Researchers at the Johns Hopkins School of Medicine report that a new National Institutes of Health-funded study is helping advance a potential new approach to treating Alzheimer’s disease. The focus is on proteins in the brain that produce small but important gases. The protein, called cystathionine gamma lyase (CSE), is best known for producing hydrogen sulfide, a gas that smells like rotten eggs, and appears to play an important role in memory formation. Study leader Dr. Bindu Paul, associate professor of pharmacology, psychiatry, and neuroscience at Johns Hopkins University School of Medicine, said the findings were made through experiments on…
On March 18, FDA released draft guidance for the validation of new approach methodologies (NAMs) involving complex methods. in vitro Model (CIVM). For a sector that has been operating for a long time without clear regulatory standards, this is critical and requires a collective response. Importantly, this is still a draft and the feedback window is a real opportunity to adjust the guidance so it reflects real-world scientific practice. This guidance is centered around four principles. The 11th Annual 3D Tissue Model Summit (Boston, MA | April 28-30, 2026) will be dedicated to each session, allowing attendees to assess the…
