- newNew cholesterol guidelines could change when you get tested
A major new U.S. cholesterol guideline is shifting the focus toward earlier, more personalized prevention of heart disease. It urges people to start screening sooner—sometimes even in childhood—and highlights the importance of tracking not just LDL (“bad”) cholesterol but also genetic risk factors like lipoprotein(a). A new, more advanced risk calculator now uses broader health data to better predict heart attack and stroke risk over decades.

- newWhat teens eat could be affecting their mental health more than we thought
What teens eat might matter more for their mental health than previously thought. A sweeping review of nearly 20 studies found that healthier diets are often linked to fewer depressive symptoms, while poor eating habits may go hand in hand with greater psychological distress. Interestingly, focusing on whole dietary patterns—not just individual nutrients—showed more consistent benefits, suggesting that overall eating habits could play a meaningful role during this critical stage of brain dev…

- newScientists say the evidence is clear: E-cigarettes beat patches and gum in helping smokers quit
Nicotine e-cigarettes may be one of the most effective tools yet for quitting smoking, according to a sweeping review of global research. By analyzing findings from 14 major reviews spanning nearly a decade, researchers found consistent, high-quality evidence showing that nicotine vapes outperform traditional methods like patches, gum, and even behavioral support. While some lower-quality studies produced mixed results, the strongest data clearly favored nicotine e-cigarettes.

- newThis new therapy turns off pain without opioids or addiction
Scientists have developed a new gene therapy that quiets pain at its source in the brain—without the addictive risks of opioids. Using AI to map how pain is processed, they created a targeted “off switch” that mimics morphine’s benefits but skips its dangerous side effects. In early tests, it delivered lasting relief without affecting normal sensations. The discovery could mark a major step toward safer, non-addictive pain treatments.

- This new carbon material could make carbon capture far more affordable
Scientists have created a new kind of carbon material that could make carbon capture much cheaper and more efficient. By carefully controlling how nitrogen atoms are arranged, they found certain structures capture CO2 better and release it using far less heat. One version works at temperatures below 60 °C, meaning it could run on waste heat instead of costly energy. The discovery offers a powerful new blueprint for next-generation climate technology.

- Popular sugar substitute linked to brain damage and stroke risk
A widely used sugar substitute found in everything from keto snacks to diet drinks may not be as harmless as it seems. New research shows that erythritol can disrupt brain blood vessel cells, reducing their ability to relax, increasing harmful oxidative stress, and impairing the body’s ability to break down clots. These changes create conditions that could raise stroke risk, even at typical consumption levels.

- Scientists discover why your appetite suddenly disappears when you’re sick
Scientists have uncovered how your body actually tells your brain to stop eating when you’re sick. In a new study, researchers found that specialized cells in the gut detect parasites and send signals that ultimately trigger the brain to suppress appetite. This process builds over time, explaining why you may feel fine at first but then suddenly lose interest in food as an infection takes hold.

- Scientists discover a hidden system that turns brown fat into a calorie burner
Scientists have identified a key biological system that helps brown fat burn energy by building the networks it needs to function. A protein called SLIT3 splits into two parts, with each piece guiding the growth of blood vessels and nerves inside brown fat. These structures allow the tissue to pull in nutrients and rapidly convert them into heat instead of storing them as fat.

- This popular supplement may increase risk of birth defects, study finds
A new study reveals that high doses of antioxidants—often seen as harmless or beneficial—may actually impact future generations. Male mice given common supplements like NAC produced offspring with subtle but significant facial and skull changes. Researchers believe this is tied to altered sperm DNA, even though the fathers showed no outward health issues.

- Scientists discover why cancer drugs don’t work for everyone
Scientists have uncovered a hidden reason why cancer treatments don’t work equally well for everyone. Certain drugs can become trapped inside lysosomes within tumor cells, forming slow-release reservoirs that create uneven drug distribution. This means some cancer cells are heavily exposed while others are barely affected. Understanding this process could help doctors better tailor treatments and improve outcomes.

- Scientists find gut bacteria inject proteins that control your immune system
Gut bacteria aren’t just passive passengers—they can actively send proteins straight into our cells. Using microscopic injection systems, even harmless microbes can influence immune responses and metabolic pathways. Researchers found these interactions may play a role in inflammatory diseases like Crohn’s. It’s a major shift in how scientists understand the microbiome’s power over human health.

- This dangerous combo in your body could raise death risk by 83%
Having both excess belly fat and low muscle mass isn’t just unhealthy—it’s potentially deadly, raising the risk of death by 83%. This condition, called sarcopenic obesity, creates a vicious cycle where fat accelerates muscle breakdown and inflammation. Researchers found it can be identified using simple measurements, not costly medical tests. That means earlier detection—and a real chance to intervene before serious decline sets in.

- Scientists discover “overflow valve” in cells linked to Parkinson’s Disease
Researchers have identified a crucial ion channel, TMEM175, that acts like an overflow valve in the cell’s recycling system. It regulates acidity inside lysosomes, ensuring they function properly. When TMEM175 is faulty, toxic buildup can occur, contributing to diseases like Parkinson’s. This breakthrough reveals a promising new target for future therapies.

- What you do in midlife could reveal how long you’ll live
By closely monitoring fish throughout their lives, researchers found that simple behaviors in midlife—like movement and sleep—can predict lifespan. Fish that stayed active and slept mostly at night tended to live longer, while those slowing down earlier lived shorter lives. Surprisingly, aging didn’t unfold smoothly but in sudden jumps between stages. The work suggests that tracking daily habits in humans could reveal early clues about how we age.

- Scientists find immune cell linked to long COVID fatigue and symptoms
Long COVID remains a frustrating medical mystery, affecting up to 1 in 10 people long after the initial infection fades. Now, scientists have uncovered a crucial clue hidden deep within the immune system. By analyzing individual immune cells, they identified a distinct molecular state in key white blood cells—especially common in patients who initially had mild or moderate COVID.
