- newMost of the world isn’t getting enough omega-3
Most people worldwide aren’t getting enough omega-3, leaving a major gap between scientific recommendations and daily diets. Researchers emphasize the critical role of EPA and DHA across all life stages and point out that food alone often can’t meet needs. The review calls for clearer global guidelines and easier access to sustainable omega-3 sources. It also highlights the challenges different populations face in reaching healthy intake levels.

- newSingle enzyme mutation reveals a hidden trigger in dementia
Researchers discovered that a tiny structural feature of the enzyme GPX4 helps keep neurons safe. A rare mutation removes this protection, allowing harmful molecules to damage cell membranes and trigger early dementia. Mouse and cell studies showed changes resembling Alzheimer’s. Early tests to slow this damage give scientists new directions to explore.

- Her food cravings vanished on Mounjaro then roared back
Deep-brain recordings showed that Mounjaro and Zepbound briefly shut down the craving circuits linked to food noise in a patient with severe obesity. Her obsessive thoughts about food disappeared as the medication quieted the nucleus accumbens, the brain’s reward hub.

- Gut molecule shows remarkable anti-diabetes power
Researchers revealed that the microbial metabolite TMA can directly block the immune protein IRAK4, reducing inflammation and improving insulin sensitivity. The molecule counteracts damage caused by high-fat diets and even protects mice from sepsis. Since IRAK4 is a known drug target, this pathway could inspire new diabetes therapies. The study highlights how gut microbes and nutrition can work together to support metabolic health.

- New study finds a silent genetic heart risk hidden in millions
A large Mayo Clinic study shows that current guidelines fail to detect nearly 90% of people with familial hypercholesterolemia, a common inherited cause of dangerously high cholesterol. Many affected individuals already had early heart disease but never met testing criteria. Routine DNA screening could dramatically expand detection and prevention. The research underscores the need for genomics-driven healthcare.

- This simple ingredient makes kale way healthier
Scientists found that kale’s prized nutrients are hard for the body to absorb unless they’re eaten with oil. Cooking doesn’t improve absorption, but adding oil-based dressings—or even more advanced nanoemulsion sauces—does. These combinations dramatically increase access to kale’s carotenoids. The research could inspire new, healthier dressings designed to supercharge everyday vegetables.

- Low dose melanoma treatment delivers dramatically better results
Using less ipilimumab appears to make melanoma immunotherapy both safer and more effective, with dramatically better response and survival outcomes. The findings suggest that reducing side effects may be the key to maximizing the benefits of these powerful treatments.

- This tiny implant sends secret messages to the brain
Researchers have built a fully implantable device that sends light-based messages directly to the brain. Mice learned to interpret these artificial patterns as meaningful signals, even without touch, sight, or sound. The system uses up to 64 micro-LEDs to create complex neural patterns that resemble natural sensory activity. It could pave the way for next-generation prosthetics and new therapies.

- Scientists uncover a volcanic trigger behind the Black Death
A newly analyzed set of climate data points to a major volcanic eruption that may have played a key role in the Black Death’s arrival. Cooling and crop failures across Europe pushed Italian states to bring in grain from the Black Sea. Those shipments may have carried plague-infected fleas. The study ties together tree rings, ice cores, and historical writings to reframe how the pandemic began.

- Garlic mouthwash shows shockingly strong germ-fighting power
Garlic extract is emerging as a surprisingly powerful contender to chlorhexidine, the long-standing “gold standard” in antimicrobial mouthwashes. A systematic review of clinical studies shows that higher-concentration garlic mouthwash can rival chlorhexidine in killing bacteria—sometimes outperforming it—while offering a more natural alternative.

- Humans are built for nature not modern life
Human biology evolved for a world of movement, nature, and short bursts of stress—not the constant pressure of modern life. Industrial environments overstimulate our stress systems and erode both health and reproduction. Evidence ranging from global fertility declines to chronic inflammatory diseases shows the toll of this mismatch. Researchers say cultural and environmental redesign, especially nature-focused planning, is essential.

- New fat-burning diabetes pill protects muscle and appetite
Researchers have developed a new oral drug that boosts metabolic activity in muscle rather than altering appetite like GLP-1 drugs. Early trials suggest it improves blood sugar control and fat metabolism while preserving muscle mass, with fewer side effects. Because it acts through a different mechanism, it could be paired with GLP-1 treatments for even stronger results.

- Scientists say this viral rosemary skincare trend actually works
Researchers have found scientific support for the viral claim that rosemary can improve wound healing. Carnosic acid, a natural antioxidant in rosemary, promoted scar-free healing in mice by activating a nerve sensor tied to regenerative repair. Rosemary proved more potent and gentler than other herbs or compounds that target the same pathway. The work hints at a low-cost future option for reducing scarring in humans.

- Scientists keep a human alive with a genetically engineered pig liver
Researchers successfully implanted a genetically modified pig liver into a human, proving that such an organ can function for an extended period. The graft supported essential liver processes before complications required its removal. Although the patient ultimately passed away, the experiment demonstrates both the potential and the complexity of xenotransplantation. Experts believe this could reshape the future of organ replacement.

- The rotten egg smell that could finally beat nail fungus
Researchers have identified hydrogen sulfide as a surprisingly effective tool for treating difficult nail infections. It penetrates nails more efficiently than current drugs and kills pathogens by disrupting their energy systems. The compound also works against fungi that resist standard antifungal treatments.
