Some people taking Ozempic, Wegovy, or Mounjaro notice that food suddenly tastes sweeter or saltier, and this subtle shift in flavor perception appears tied to reduced appetite and stronger feelings of fullness. In a study of more than 400 patients, roughly one in five experienced heightened taste sensitivity, and many reported being less hungry and more easily satisfied.

People taking semaglutide report far fewer obsessive thoughts about food, with cravings dropping sharply and mental health improving. This new research hints the drug may offer freedom from the constant distraction of food noise.

QROCODILE has set record-breaking sensitivity in the search for dark matter, detecting signals at energy levels once thought impossible. These results may be just the first step toward finally capturing direct evidence of the universe’s hidden mass.

Eating more like the Mediterranean—rich in vegetables, legumes, fruits, and olive oil—may do more than just support heart health. A new King’s College London study suggests it also protects against gum disease by lowering inflammation markers in the blood.

Preschoolers with ADHD are often given medication right after diagnosis, against medical guidelines that recommend starting with behavioral therapy. Limited access to therapy and physician pressures drive early prescribing, despite risks and reduced effectiveness in young children.

Scientists at UC San Diego have identified a new drug, ION224, that could transform the treatment of MASH, a dangerous form of fatty liver disease tied to obesity and diabetes. By blocking a key liver enzyme, the drug reduces fat and inflammation, halting the root causes of liver damage. In a year-long clinical trial, patients showed major improvements without serious side effects, offering hope to millions affected worldwide.

NASA’s Perseverance rover has delivered its most compelling clue yet in the search for life on Mars. A rock sample called “Sapphire Canyon,” taken from the Bright Angel formation in Jezero Crater, shows unusual mineral patterns known as “leopard spots” that may have formed through microbial activity. While non-biological processes could also explain the find, scientists say the chemical fingerprints look strikingly similar to those left behind by microbes on Earth.

Behind the dusty clouds of the Cigar Galaxy lies a dazzling powerhouse of star formation, where stars are being born ten times faster than in the Milky Way. Astronomers using the Hubble Space Telescope have uncovered massive super star clusters in its core, each glowing with hundreds of thousands of stars and shining brighter than typical clusters. These observations reveal not only the galaxy’s extraordinary pace of star creation but also provide a rare look into how such enormous clusters develop and evolve.

Researchers from the University of Waterloo discovered that measuring long-term stress through children’s hair samples can reveal early signs of mental health risks in those living with chronic physical illnesses. Children with persistently high cortisol were more likely to struggle with anxiety, depression, and behavioral challenges, while those whose stress markers declined showed fewer problems.

Scientists at Cold Spring Harbor Laboratory have cracked open the secrets of plant stem cells, mapping key genetic regulators in maize and Arabidopsis. By using single-cell RNA sequencing, they created a gene expression atlas that identifies rare stem cell regulators, links them to crop size and productivity, and offers a new roadmap for breeding resilient, high-yield plants.

Volcanic eruptions on the remote island of Nishinoshima repeatedly wipe the land clean, giving scientists a rare chance to study life’s earliest stages. Researchers traced the genetic origins of an extinct purslane population to nearby Chichijima but found striking quirks—evidence of a founder’s effect and genetic drift. These discoveries shed light on how plants recolonize harsh environments and how ecosystems evolve from scratch.

A groundbreaking project is piecing together Leonardo da Vinci’s genetic profile by tracing his lineage across 21 generations and comparing DNA from living descendants with remains in a Da Vinci family tomb. If successful, the effort could reveal new insights into Leonardo’s health, creativity, and even help confirm the authenticity of his works.

On remote islands of Papua New Guinea, people carry a story that ties us all back to our deepest roots. Although their striking appearance once puzzled scientists, new genetic evidence shows they share a common ancestry with other Asians, shaped by isolation, adaptation, and even interbreeding with mysterious Denisovans. Yet, their unique history — marked by survival bottlenecks and separation from farming-driven booms — leaves open questions about the earliest migrations out of Africa and whether their lineage holds traces of a forgotten branch of humanity.

A 28-day trial showed that pterostilbene cream improved wrinkles, skin firmness, collagen, and pore size far better than a control emulsion. The results highlight pterostilbene as a promising natural ingredient for next-generation anti-aging skincare.

Scientists are unraveling the mysteries of "steam worlds"—exoplanets known as sub-Neptunes that are rich in water but orbit so close to their stars that their surfaces are shrouded in thick atmospheres of vapor. Using advanced models, researchers at UC Santa Cruz are now mapping how water behaves under extreme pressures and temperatures, offering insights into exotic phases like supercritical fluids and superionic ice.

A sweeping global study reveals that nearly half of people with diabetes don’t even know they have it, with young adults being the most overlooked. While most diagnosed patients receive treatment, less than half achieve proper blood sugar control, leaving only about one in five with well-managed diabetes.

Nature has long been the source of lifesaving medicines, from willow bark’s natural aspirin to new discoveries in tropical fruits. Now, chemists at the University of Delaware have pioneered a way to recreate powerful molecules from guava plants that show promise against liver cancer. Their method provides a low-cost, scalable recipe for scientists worldwide, sparking collaboration and potentially transforming cancer treatment.

Researchers discovered two new parasitic wasp species living in the U.S., tracing their origins back to Europe and uncovering clues about how they spread. Their arrival raises fresh questions about biodiversity, ecological risks, and the role of citizen science in tracking hidden species.

Eye drops combining pilocarpine and diclofenac helped patients read extra lines on vision charts, with effects lasting up to two years. The treatment could revolutionize presbyopia care as a safe, non-surgical alternative to glasses.

Dry eyes are far more common than previously believed, with over half of adults in the US and Europe experiencing symptoms, yet most remain undiagnosed for years. The large-scale NESTS study reveals that sufferers often endure daily discomfort that disrupts work, driving, and even surgery outcomes. Many accept the condition as part of aging, unaware that simple treatments could provide relief.
