Known as NAD⁺, it plays a crucial role in keeping our cells energized, repairing DNA, and maintaining overall health—but its levels steadily decline over time, potentially fueling diseases like Alzheimer’s and Parkinson’s. Researchers are now exploring ways to boost NAD⁺ using compounds like NR and NMN, with early studies hinting at improvements in memory, metabolism, and physical function. Tue, 24 Mar 2026 06:39:06 EDT https://www.sciencedaily.com/releases/2026/03/260324024253.htm https://www.sciencedaily.com/releases/2026/03/260323005545.htm A surprising new study reveals that blocking a supposedly protective enzyme, Caspase-2, could actually backfire—raising the risk of chronic liver damage and cancer over time. Researchers found that without this enzyme, liver cells grow abnormally large and accumulate genetic damage, leading to inflammation, scarring, and eventually tumors, especially with age. While inhibiting Caspase-2 may offer short-term benefits, such as reducing fatty liver disease, the long-term consequences appear dangerous.

Researchers at Mass General Brigham found that taking high doses of vitamin D3 did not make COVID-19 infections less severe or reduce hospital visits. However, the study uncovered a subtle but intriguing signal suggesting that people who consistently took vitamin D supplements might be slightly less likely to develop long COVID symptoms weeks after infection. Sun, 15 Mar 2026 05:54:54 EDT https://www.sciencedaily.com/releases/2026/03/260315001845.htm https://www.sciencedaily.com/releases/2026/03/260311213453.htm Scientists have discovered that a rare “mirror-image” version of the amino acid cysteine can dramatically slow the growth of certain cancers while leaving healthy cells largely untouched. Unlike most anticancer treatments that harm normal tissues, this molecule—called D-cysteine—is taken up mainly by some cancer cells through a specific transporter on their surface. Once inside, it shuts down a crucial mitochondrial enzyme that cancer cells rely on to produce energy and maintain DNA, effectively halting their growth. Thu, 12 Mar 2026 18:48:39 EDT https://www.sciencedaily.com/releases/2026/03/260311213453.htm https://www.sciencedaily.com/releases/2026/03/260311004833.htm Coenzyme A, a molecule derived from vitamin B5, is vital for metabolism throughout the body. Scientists discovered that most of it resides inside mitochondria, yet how it reached these cellular powerhouses was unclear. Yale researchers have now identified the transport system that moves CoA into mitochondria, solving a long-standing biological puzzle. The discovery could help researchers better understand diseases linked to metabolic dysfunction and mitochondrial problems. Wed, 11 Mar 2026 18:32:18 EDT https://www.sciencedaily.com/releases/2026/03/260311004833.htm https://www.sciencedaily.com/releases/2026/03/260309225146.htm Scientists at Oregon Health & Science University have developed a new molecule that could open the door to treating triple-negative breast cancer, one of the most aggressive and difficult-to-treat forms of the disease. The compound, called SU212, targets and disables a key enzyme that cancer cells rely on to fuel their growth. In tests using humanized mouse models, the molecule caused tumors to shrink and slowed the spread of cancer by forcing the enzyme to break down. Tue, 10 Mar 2026 18:10:14 EDT https://www.sciencedaily.com/releases/2026/03/260309225146.htm https://www.sciencedaily.com/releases/2026/03/260309183010.htm Researchers have found hundreds of metabolic enzymes attached to human DNA inside the cell nucleus. Different tissues and cancers show unique patterns of these enzymes, forming a “nuclear metabolic fingerprint.” Some of the enzymes gather around damaged DNA to assist with repair. The discovery reveals an unexpected link between metabolism and gene regulation that could influence how cancers grow and respond to treatment. Mon, 09 Mar 2026 19:54:17 EDT https://www.sciencedaily.com/releases/2026/03/260309183010.htm https://www.sciencedaily.com/releases/2026/03/260308201618.htm Pre-workout supplements promising extra energy for workouts may come with a hidden cost: severely reduced sleep. A study of people aged 16–30 found users were more than twice as likely to sleep five hours or less per night. Many of these products pack huge doses of caffeine and stimulants that can linger for hours. Researchers say the findings raise concerns about the impact on young people’s health and development.

Fiber plays a powerful role in keeping the body healthy, from supporting digestion and feeding beneficial gut microbes to helping regulate blood sugar and cholesterol. Researchers say getting enough fiber may even lower the risk of conditions like obesity, diabetes, and certain cancers. Sun, 08 Mar 2026 15:57:15 EDT https://www.sciencedaily.com/releases/2026/03/260307213252.htm https://www.sciencedaily.com/releases/2026/03/260307213236.htm A major international trial has found that daily fish oil supplements significantly reduced life-threatening cardiovascular events in dialysis patients. People who took four grams per day had a 43% lower risk of heart attack, stroke, cardiac death, or vascular-related amputations compared with those on placebo. The findings stand out because few treatments have successfully lowered heart risk in this high-risk group.

People with metabolic syndrome who followed a short, calorie-reduced oat-based plan saw their harmful LDL cholesterol drop by 10%, along with modest weight loss and lower blood pressure. Even more surprising, the cholesterol benefits were still visible six weeks later. Wed, 25 Feb 2026 11:37:57 EST https://www.sciencedaily.com/releases/2026/02/260225081217.htm https://www.sciencedaily.com/releases/2026/02/260225081214.htm Avoiding meat might slightly lower the odds of reaching 100 — but only for frail, underweight seniors. In very old age, staying strong and maintaining muscle matters more than long-term disease prevention. Older adults who included fish, eggs, or dairy were just as likely to become centenarians as meat eaters, suggesting that key nutrients may make the difference. The takeaway: nutrition needs change dramatically with age.

While it can kill bacteria, it only works at levels that also damage human cells and beneficial gut microbes. Scientists warn that homemade MMS mixtures are especially dangerous due to wildly inconsistent dosing. The study calls MMS a clear case where the risks are high—and the benefits are effectively zero.

Researchers found that modest sodium reductions in bread, packaged foods, and takeout meals could significantly reduce heart disease and stroke rates in France and the U.K. The key advantage is that people would not need to alter their eating habits at all. Small changes to the food supply could deliver large, long-term health benefits.

Higher-quality studies show little benefit, and your body doesn’t absorb collagen in the way ads suggest. Some supplements may even pose safety concerns and lack proper testing. Experts recommend focusing on proven habits like sunscreen, retinoids, and a nutrient-rich diet instead.

The compound improves communication between brain cells and restores early memory abilities that typically fade first. Because it already exists in the body and declines with age, boosting it may offer a safer way to protect the brain. The discovery hints at a new strategy for slowing cognitive ageing before severe damage sets in.

They identified multiple DNA regions linked to bowel movement frequency, confirming known gut pathways and revealing new ones. The biggest surprise was a strong connection to vitamin B1, a common nutrient not usually linked to digestion.

A common bacterium found in long-lasting wounds does not just resist drugs. It actively releases damaging molecules that overwhelm skin cells and stop them from repairing tissue. Researchers discovered that neutralizing these harmful molecules with antioxidants allows skin cells to recover and restart healing.

In animal models, low-dose THC reduced inflammation, improved gut bacteria, boosted serotonin, and lowered harmful cholesterol and bile acids. Surprisingly, it also reduced circulating levels of antiretroviral drugs while maintaining viral suppression, potentially protecting the liver. Scientists say the results point to a promising new approach for managing chronic complications of HIV.

Researchers created a new technique that traps tiny amounts of the extract inside microscopic capsules, preventing evaporation and irritation. The method delivers consistent nanodoses and could eventually be used in medicines or food products. It may also work for many other natural extracts.

A comprehensive review found they can help control blood sugar, support heart and gut health, and reduce inflammation and oxidative stress. Laboratory and human studies also suggest bamboo may promote beneficial gut bacteria and reduce toxic compounds in cooked foods. However, bamboo must be pre-boiled to avoid natural toxins.

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.

Inside the capsule is a biodegradable antenna that sends a signal within minutes of ingestion, then safely dissolves. The system is designed to work with existing medications and could help doctors track adherence for high-risk patients. Researchers hope it will prevent missed doses that can lead to serious health consequences. Tue, 13 Jan 2026 00:55:51 EST https://www.sciencedaily.com/releases/2026/01/260112214259.htm
