- newA hidden brain signal may reveal Alzheimer’s long before diagnosis
Researchers have discovered a brain activity pattern that can predict which people with mild cognitive impairment are likely to develop Alzheimer’s disease. Using a noninvasive brain scanning technique and a custom analysis tool, they detected subtle changes in electrical signals tied to memory processing years before diagnosis. The findings point to a new way of spotting Alzheimer’s early—by listening directly to how neurons behave.

- newWhy music brings no joy to some people
A small group of people experience no pleasure from music despite normal hearing and intact emotions. Brain imaging reveals that their auditory and reward systems fail to properly communicate, leaving music emotionally flat. Researchers developed a questionnaire to measure how rewarding music feels across emotions, mood, movement, and social connection. The findings suggest pleasure isn’t all-or-nothing and may depend on how specific brain networks connect.

- newHow Ozempic and Wegovy are quietly cutting America’s food bills
Weight-loss drugs like Ozempic and Wegovy are changing how Americans spend money on food. A large Cornell study found households cut grocery spending by over 5% within six months, with even bigger drops at fast-food restaurants. Snack foods and sweets saw the steepest declines, while only a few categories like yogurt and fruit rose slightly. The effects linger for at least a year among continued users.

- newA little-known health syndrome may affect nearly everyone
Most U.S. adults have risk factors tied to a little-known condition called CKM syndrome, which connects heart disease, kidney problems, diabetes, and obesity into one powerful health threat. When these issues overlap, the danger rises far more than when they occur alone. Despite low awareness, people are eager to learn how CKM is diagnosed and treated. Experts say understanding how these systems work together could prevent serious, life-threatening events.

- newA massive gene hunt reveals how brain cells are made
A large genetic screen has revealed how stem cells transform into brain cells, exposing hundreds of genes that make this process possible. Among the discoveries is PEDS1, a gene now linked to a previously unknown neurodevelopmental disorder in children. When PEDS1 does not work properly, brain growth and nerve cell formation are impaired. The findings help explain how early genetic changes can shape brain development and disease.

- Newly discovered coffee compounds beat diabetes drug in lab tests
Roasted coffee may do more than wake you up—it could help control blood sugar. Researchers discovered several new coffee compounds that inhibit α-glucosidase, a key enzyme linked to type 2 diabetes. Some of these molecules were even more potent than a common anti-diabetic drug. The study also introduced a faster, greener way to uncover health-boosting compounds in complex foods.

- Injection turns sleeping tumor immune cells into cancer fighters
KAIST researchers have developed a way to reprogram immune cells already inside tumors into cancer-killing machines. A drug injected directly into the tumor is absorbed by macrophages, prompting them to recognize and attack cancer cells while activating nearby immune defenses. This eliminates the need for lab-based cell extraction and modification. In animal models, the strategy significantly slowed tumor growth and sparked strong anticancer immune responses.

- A room full of flu patients and no one got sick
In a striking real-world experiment, flu patients spent days indoors with healthy volunteers, but the virus never spread. Researchers found that limited coughing and well-mixed indoor air kept virus levels low, even with close contact. Age may have helped too, since middle-aged adults are less likely to catch the flu than younger people. The results highlight ventilation, air movement, and masks as key defenses against infection.

- A daily fish oil supplement slashed serious heart risks in dialysis patients
A new international trial has delivered striking results for people on dialysis, showing that daily fish oil supplements can sharply reduce serious heart-related events. Patients taking fish oil had far fewer heart attacks, strokes, and cardiac deaths than those on placebo. Researchers say this is especially important because dialysis patients face extreme cardiovascular risk and few proven treatment options. The findings mark a rare breakthrough in kidney care.

- Scientists uncover a hidden aging program in the gut that fuels cancer risk
Although the gut renews itself constantly, its stem cells accumulate age-related molecular changes that quietly alter how genes are switched on and off. Scientists found that this “epigenetic drift” follows a clear pattern and appears in both aging intestines and most colon cancers. Some regions age faster than others, forming a patchwork of weakened tissue more prone to degeneration. Encouragingly, researchers showed this drift can be slowed—and partly reversed—by restoring iron levels…

- Sleeping less than 7 hours could cut years off your life
Sleep isn’t just about feeling rested—it may be one of the strongest predictors of how long you live. Researchers analyzing nationwide data found that insufficient sleep was more closely tied to shorter life expectancy than diet, exercise, or loneliness. The connection was consistent year after year and across most U.S. states. The takeaway is simple but powerful: getting seven to nine hours of sleep may be one of the best things you can do for long-term health.

- Study shows young blood can slow Alzheimer’s in mice
New research shows that aging blood can accelerate Alzheimer’s-like changes in the brain, while younger blood may offer protection. In mouse experiments, older blood worsened memory performance and increased toxic protein buildup linked to the disease. The study also uncovered widespread changes in brain proteins tied to communication and signaling. The findings point to the blood as a powerful influencer of brain health—and a promising new therapeutic target.

- A hidden loop is powering deadly pancreatic cancer
Pancreatic cancer is notoriously hard to treat, often resisting therapies that target its most common mutations. Researchers have now uncovered a hidden three-part loop that fuels tumor growth, involving the cancer drivers SRSF1, AURKA, and MYC. By targeting just one part of this loop with a specially designed molecule, they were able to shut down all three at once. The result was a dramatic loss of tumor cell survival, offering new hope for smarter, more effective treatments.

- This natural amino acid could help stop cavities before they start
Sugar-loving mouth bacteria create acids that damage teeth, but arginine can help fight back. In a clinical trial, arginine-treated dental plaque stayed less acidic, became structurally less harmful, and supported more beneficial bacteria. These changes made the biofilms less aggressive after sugar exposure. The results point to arginine as a promising, natural addition to cavity-prevention strategies.

- Scientists test a tiny eye implant that could restore sight
Scientists at USC are launching a new trial to test a tiny stem cell implant that could restore vision in people with advanced dry macular degeneration. The hair-thin patch replaces damaged retinal cells responsible for sharp, central vision. Earlier studies showed the implant was safe and helped some patients see better. Researchers now hope it can deliver meaningful, lasting improvements in eyesight.
