A little-known tree from Brazil’s Atlantic Forest may hold a surprising weapon against COVID-19. Researchers discovered that compounds called galloylquinic acids, extracted from its leaves, can attack SARS-CoV-2 on multiple fronts—blocking the virus from entering cells, disrupting its replication, and even dampening harmful inflammation. Unlike many antivirals that target just one part of the virus, these natural compounds act in several ways at once, potentially making it harder for resistance to develop.

Eating eggs might do more than just start your day—it could help protect your brain. Researchers found that people 65 and older who eat eggs regularly have a significantly lower risk of developing Alzheimer’s disease, with daily or near-daily consumption linked to up to a 27% reduction. Even modest egg intake showed benefits, suggesting that small dietary changes could make a meaningful difference over time.

Researchers have created a next-generation obesity drug that works like a “Trojan horse,” using GLP-1/GIP signals to slip a powerful metabolic enhancer directly into target cells. In mice, it outperformed existing treatments—curbing appetite, increasing weight loss, and improving blood sugar levels. Because the extra drug acts only where it’s needed, it can be used at much lower doses, potentially reducing side effects.

Some people taking Ozempic-like diabetes drugs may be getting dramatically better results for a surprising reason: why they overeat in the first place. A year-long study in Japan found that people who tend to eat because tempting food looks or smells irresistible were much more likely to lose weight and improve blood sugar levels on GLP-1 medications. But people who eat mainly in response to stress, sadness, or emotional struggles didn’t see the same long-term benefits.

Aging doesn’t just add fat—it redistributes it in risky ways, pushing more into the abdomen where it can harm health. Scientists found that testosterone plays a key role in this shift. In older women recovering from hip fractures, a testosterone gel combined with exercise helped prevent the usual rise in dangerous visceral fat. The result could point to a powerful new strategy for improving recovery and long-term health.

A new twin study suggests your genes may play a bigger role in your future success than your upbringing. Researchers found that IQ, which is largely genetically influenced, strongly predicts education, career, and income. Even twins raised in the same household diverged based on genetic differences. The findings hint that life outcomes may be more hardwired than many people expect.

Scientists in Sweden have taken a major step toward a potential cure for type 1 diabetes by developing a more reliable way to create insulin-producing cells from human stem cells. These lab-grown cells not only respond strongly to glucose but were also able to restore blood sugar control when transplanted into diabetic mice.

MIT neuroscientists have uncovered a surprising secret hidden in the adult brain: millions of “silent synapses,” dormant connections that lie in wait until new learning calls them into action. Once thought to exist only in early development, these inactive links make up about 30% of synapses in the adult cortex and can be rapidly activated to form fresh memories.

A short burst of immunotherapy before surgery is delivering surprisingly powerful results for a specific type of colorectal cancer. Patients in a UK-led trial who received just nine weeks of pembrolizumab prior to surgery have remained cancer-free nearly three years later—an outcome that challenges the standard approach of surgery followed by months of chemotherapy.

A major 10-year clinical trial is turning one of the world’s most common knee surgeries on its head. Researchers found that trimming a damaged meniscus—a procedure long believed to relieve pain—offers no real benefit over placebo surgery. Even more surprising, patients who had the operation actually fared worse over time, with more symptoms, poorer function, faster progression of osteoarthritis, and a greater likelihood of needing additional surgery.
