MIT Professor Susumu Tonegawa, renowned molecular biologist and Nobel laureate, dies at 86
Tonegawa made landmark discoveries about how the immune system generates antibody diversity and how the brain forms memories.
Study shows a blood test can help identify healthy people at high risk for Alzheimer’s disease
A blood test may predict if apparently healthy older adults are likely to develop Alzheimer’s symptoms in the next five or 10 years, researchers reported Wednesday.
Blood-based test can predict risk of developing symptoms of Alzheimer’s up to a decade early
A blood test for the biomarker phosphorylated tau 217 (p-tau217) recently received federal clearance, but questions have emerged about the extent to which such tests can accurately predict whether a cognitively healthy individual will develop cognitive impairment—a key symptom of Alzheimer’s disease.
Researchers develop light-activated drugs that restore sight in blind mice
Blinding diseases caused by the degeneration of photoreceptors, such as age-related macular degeneration (AMD) and retinitis pigmentosa (RP), affect 200 million people worldwide and represent the leading causes of visual impairment and blindness.
New machine-learning equation accurately assess LDL cholesterol risk
The Martin-Hopkins equation to assess low-density lipoprotein (LDL) cholesterol levels in blood samples has been used by laboratories in the U.S. and other countries to guide efforts to lower cardiovascular disease risk. Now, a simplified machine-learning version of this equation has been shown in a study of millions of U.S. adult and child blood samples to match the accuracy of the original—making it broadly accessible.
AI flags heart failure risk five years early from routine ECG recordings
Researchers at the Technion Faculty of Biomedical Engineering have achieved a breakthrough in the early detection of heart failure.
Bile acid buildup drives spread of breast cancer, discovery reveals
A buildup of bile acids caused by an unhealthy gut can drive breast cancer to other parts of the body, new University of Virginia Comprehensive Cancer Center research reveals. The findings could open the door to new ways to prevent breast cancer metastasis (spread), improve patient outcomes and save lives.
The invisible wearable: New skin sensors advance health monitoring
While wearable health sensors are becoming increasingly common, current iterations are awkward to wear. For example, devices attached to the face can draw unwanted attention, increase self-consciousness and influence the signals users are trying to measure. However, recent research may have found a solution by introducing ultrathin sensors that cannot be seen by observers or felt by the wearer.
