Researchers discovered that omega-3s like EPA and DHA help curb colorectal cancer only when the enzyme ALOX15 is present. Without it, fish oil sometimes increased tumor growth in mice—especially DHA. The results suggest that not all supplements work the same way, and genetics could determine who truly benefits.

Memory problems, depression, sleep issues, weight gain, and many other symptoms appeared just as often in people taking a placebo. Only a few side effects showed any link to statins — and even those were rare. Sun, 15 Feb 2026 00:35:50 EST https://www.sciencedaily.com/releases/2026/02/260212025550.htm https://www.sciencedaily.com/releases/2026/01/260131084610.htm Statins are a cornerstone of heart health, but muscle pain and weakness cause many patients to quit taking them. Scientists have now identified the precise molecular trigger behind these side effects. They found that statins jam open a critical muscle protein, causing a toxic calcium leak. The discovery could lead to safer statins that keep their life-saving benefits without the muscle damage.

Scientists have now developed a drug that shuts down this pathway, dramatically boosting immune responses and slowing cancer growth in preclinical studies. Fri, 16 Jan 2026 06:06:55 EST https://www.sciencedaily.com/releases/2026/01/260115022808.htm https://www.sciencedaily.com/releases/2026/01/260114084122.htm A new discovery may explain why so many people abandon cholesterol-lowering statins because of muscle pain and weakness. Researchers found that certain statins can latch onto a key muscle protein and trigger a tiny but harmful calcium leak inside muscle cells. That leak may weaken muscles directly or activate processes that slowly break them down, offering a long-sought explanation for statin-related aches. Wed, 14 Jan 2026 11:06:53 EST https://www.sciencedaily.com/releases/2026/01/260114084122.htm https://www.sciencedaily.com/releases/2025/12/251228020010.htm A randomized trial from Vanderbilt-Ingram Cancer Center reveals that magnesium may be the missing key to keeping vitamin D levels in balance. The study found that magnesium raised vitamin D in people who were deficient while dialing it down in those with overly high levels—suggesting a powerful regulating effect. This could help explain why vitamin D supplements don’t work the same way for everyone and why past studies linking vitamin D to cancer and heart disease have produced mixed results.

Increased intake of plant foods, even “unhealthy” ones, was strongly associated with greater weight loss. Mon, 24 Nov 2025 11:03:07 EST https://www.sciencedaily.com/releases/2025/11/251124094317.htm https://www.sciencedaily.com/releases/2025/11/251110021043.htm Intermountain Health researchers discovered that customizing vitamin D3 doses for heart attack survivors slashed their risk of another heart attack by 50%. The strategy involved frequent monitoring and dose adjustments to reach ideal vitamin D levels. Traditional studies didn’t track blood levels, missing this critical link. Mon, 10 Nov 2025 07:45:02 EST https://www.sciencedaily.com/releases/2025/11/251110021043.htm https://www.sciencedaily.com/releases/2025/10/251022023122.htm Researchers have developed a DNA-based therapy that targets the PCSK9 gene to lower cholesterol naturally. Using polypurine hairpins, they increased cholesterol uptake by cells and reduced artery-clogging lipid levels. The results show dramatic drops in PCSK9 and cholesterol levels in animal models, pointing to a safer and more effective alternative to statins.

Their experiments in mice show that supplementing with specific polyunsaturated fatty acids, not just DHA, can restore visual function and even reverse cellular aging signs. Tue, 14 Oct 2025 09:07:15 EDT https://www.sciencedaily.com/releases/2025/10/251014014307.htm https://www.sciencedaily.com/releases/2025/10/251004092911.htm Scientists discovered that vitamin D2 supplements can lower levels of vitamin D3, the form the body uses most effectively. Unlike D2, vitamin D3 enhances the immune system’s first line of defense against infections. This raises questions about which type of supplement should be prioritized. Sat, 04 Oct 2025 11:34:43 EDT https://www.sciencedaily.com/releases/2025/10/251004092911.htm https://www.sciencedaily.com/releases/2025/09/250924012257.htm For decades, scientists believed Alzheimer’s was driven mainly by sticky protein plaques and tangles in the brain. Now Purdue researchers have revealed a hidden culprit: fat. They found that brain immune cells can become clogged with fat, leaving them too weak to fight off disease. By clearing out this fat and restoring the cells’ defenses, researchers may have uncovered an entirely new way to combat Alzheimer’s — shifting the focus from plaques alone to how the brain handles fat.

Most people aren’t active enough—and many are underdiagnosed—so starting treatment strong is key. Wed, 30 Jul 2025 23:57:41 EDT https://www.sciencedaily.com/releases/2025/07/250730030356.htm https://www.sciencedaily.com/releases/2025/07/250720034024.htm What if mRNA vaccines could be made more powerful and less irritating? Scientists at the University of Pennsylvania have found a way to do just that—by tweaking a key molecule in the vaccine’s delivery system. Using a century-old chemical trick called the Mannich reaction, they added anti-inflammatory phenol groups to the lipids that carry mRNA into cells. The result? A new class of lipids that reduce side effects, boost gene-editing success, fight cancer more effectively, and supercharge vaccines like those for COVID-19. This breakthrough could change how we build the next generation of vaccines and therapies.

In a 16-week crossover study, overweight adults who ditched animal products for a low-fat vegan menu saw their bodies become less acidic and dropped an average of 13 pounds—while the Mediterranean diet left weight unchanged. Researchers link the shift to lower “dietary acid load,” a hidden inflammation trigger driven by meat, eggs, and cheese.

Scientists discovered that oleic acid, a major component of many high-fat foods, uniquely spurs the growth of new fat cells by manipulating specific proteins in the body. Unlike other fats, it boosts the number of "fat cell soldiers," setting the stage for obesity and possibly chronic diseases. This unexpected twist reveals that the type of fat we eat, not just how much, may play a crucial role in our health.

As described in the journal New Phytologist, the scientists identified and successfully altered key portions of a protein that protects newly synthesized oil droplets. The genetic alterations essentially protect the oil-protector protein so more oil can accumulate.

In a recent study, researchers identified a novel cleavage enzyme of SREBP-1c, a key player in fatty acid biosynthesis. Moreover, the team unveiled, for the first time, that the biosynthesis process of fatty acid in the liver is activated by saturated fatty acids and inhibited by polyunsaturated fatty acids, providing new insights into the intricate workings of this cleavage system.
