A vitamin A byproduct has been found to quietly disarm the immune system, allowing tumors to evade attack and weakening cancer vaccines. Scientists have now developed a drug that shuts down this pathway, dramatically boosting immune responses and ...

Tryptophan does far more than help us sleep--it fuels brain chemistry, energy production, and mood-regulating neurotransmitters. But as the brain ages or develops neurological disease, this delicate system goes awry, pushing tryptophan toward harmful ...

New research suggests statins may protect adults with type 2 diabetes regardless of how low their predicted heart risk appears. In a large UK study, statin use was linked to fewer deaths and major cardiac events across all risk levels. Even those ...

Spikes in blood sugar after eating may be more dangerous for the brain than previously thought. In a massive genetic study, people with higher post-meal blood sugar had a much greater risk of Alzheimer's disease. The effect couldn't be explained by . ...

"BPA-free" food packaging may be hiding new risks. A McGill University study found that several BPA substitutes used in grocery price labels can seep into food and interfere with vital processes in human ovarian cells. Some triggered unusual fat ...

Pancreatic cancer uses a sugar-coated disguise to evade the immune system, helping explain why it's so hard to treat. Northwestern scientists discovered this hidden mechanism and created an antibody that strips away the tumor's protective signal. In ...

Researchers have discovered a rare new type of diabetes that affects babies early in life. The condition is caused by changes in a single gene that prevent insulin-producing cells from working properly. When these cells fail, blood sugar rises and .. ...

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 ...

Scientists are taking a closer look at monk fruit and discovering it's more than just a sugar substitute. New research shows its peel and pulp contain a rich mix of antioxidants and bioactive compounds that may support health. Different varieties ...

A massive international brain study has revealed that memory decline with age isn't driven by a single brain region or gene, but by widespread structural changes across the brain that build up over time. Analyzing thousands of MRI scans and memory .. ...
