Researchers analyzing data from more than 214,000 people found that dementia risk factors differ widely across countries, challenging the idea of a one-size-fits-all prevention strategy. At the same t
Researchers found that bacteria linked to gum disease may help drive the development of calcific aortic valve stenosis by triggering inflammation and calcium buildup in the heart valve. The early find
A surge of cases of the intestinal illness that causes diarrhea and fatigue has been detected in 34 states. Here's how what to do if you suspect you have it and how to avoid infection.
Researchers found that tau is essential for turning new experiences into lasting memories by helping organize the brain's memory-storing cells. The mouse study also revealed how abnormal tau may contr
The guidance over leftover breast milk says toss it after 2 hours. But a recent preprint study shared on social media has some people questioning that advice.
A simple, non-invasive ultrasound treatment could one day help injured joints heal instead of remaining trapped in a cycle of damaging inflammation. Researchers at The University of Alabama in Huntsvi
Scientists have uncovered evidence that serotonin, the chemical best known for regulating mood, may also speed the progression of a common heart valve disease in some people. The research suggests tha
Yale scientists discovered two neuron surface proteins that appear to help spread the toxic protein linked to Parkinson’s disease. Blocking these proteins in mice dramatically reduced disease progress
Researchers found that the common blood pressure drug telmisartan can significantly improve the performance of the cancer drug olaparib, potentially expanding its benefits beyond patients with BRCA-re
An experimental drug called DT-109 reversed severe fatty liver disease in animal studies by repairing the gut and preventing harmful toxins from damaging the liver. The discovery could open the door t
Researchers found that every pregnancy rewires the brain in its own way, with a second pregnancy bringing a different pattern of changes than the first. The discoveries could lead to better ways to re
Many of the body's biggest flaws are the result of evolution building on old designs instead of starting over. Our spine, eyes, teeth, pelvis, and even certain nerves all reveal compromises that worke
A new study found that dietary fiber can determine whether beneficial intestinal worms help reduce inflammation or become essentially inactive. With plenty of fiber, the worms remained healthy and sup
Heavy marijuana smoking may raise the risk of lung cancer and several head and neck cancers, according to growing research, but many important questions remain unanswered. Scientists are still trying
Michigan reports 1,250 cases of cyclospora and CDC surveillance shows cases in 17 states. The CDC has initiated a traceback investigation, as the source is not yet known.
Scientists have redesigned a key piece of MRI hardware using metamaterials, allowing existing scanners to produce clearer images of difficult-to-see parts of the body in less time. The breakthrough co
A naturally occurring bacterium from amphibian intestines completely eliminated colorectal tumors in mice with a single treatment by both attacking cancer cells and activating the immune system. The f
Scientists found that a modified Mediterranean-style diet with low protein and just enough methionine helped mice live healthier lives while reducing body fat and frailty. Human data also linked lower
