Blood test detects Parkinson’s years before symptoms appear using RNA markers

A new study identifies a blood-based biomarker that detects pre-symptomatic Parkinson’s disease by measuring the ratio of specific nuclear and mitochondrial transfer RNA fragments. The test outperforms standard clinical tools and may also reflect disease mechanisms related to impaired protein synthesis.

Pregnancy complications may predict future heart disease risk

Complications during pregnancy (or adverse pregnancy outcomes), like gestational diabetes and newly developed high blood pressure, act as nature's stress test and may uncover an individual's risk for heart disease later in life, according to new research published in the JACC, the flagship journal of the American College of Cardiology.

Scientists identify critical enzymes for astrocytic GABA production in Alzheimer’s disease

A research team at the Institute for Basic Science (IBS) has identified a previously unknown enzyme, SIRT2, that plays a key role in memory loss associated with Alzheimer's disease (AD).

Gut imbalances in autism linked to brain and behavior changes

A new USC study suggests that gut imbalances in children with autism may create an imbalance of metabolites in the digestive system - ultimately disrupting neurotransmitter production and influencing behavioral symptoms.

AI tool simulates heart scarring to personalize atrial fibrillation treatment

Researchers from Queen Mary University of London have developed an AI tool that creates synthetic yet medically accurate models of fibrotic heart tissue (heart scarring), aiding treatment planning for atrial fibrillation (AF) patients.

Bacteria engineered for remote sensing through color signatures

Bacteria can be engineered to sense a variety of molecules, such as pollutants or soil nutrients. In most cases, however, these signals can only be detected by looking at the cells under a microscope or similarly sensitive lab equipment, making them impractical for large-scale use.

Immune system selects the best T cells for targeted defense

The research groups led by Wolfgang Kastenmüller and Georg Gasteiger employed innovative microscopy techniques to observe how specific immune cells, known as T-cells, are activated and proliferate during a viral infection.

Genetic test outperforms PSA and MRI in spotting deadly prostate cancer early

A UK study found that using a polygenic risk score to identify men at highest genetic risk of prostate cancer significantly improved detection of clinically important disease. This approach caught aggressive cancers that standard PSA and MRI screening would have missed.

USC researchers reveal brain activity behind post stroke urinary incontinence

A new USC-led study using functional magnetic resonance imaging (fMRI) reveals the neural mechanisms that contribute to urinary incontinence, a common condition affecting stroke survivors that has a significant impact on their quality of life.

AI-powered digital twin of mouse visual cortex

Much as a pilot might practice maneuvers in a flight simulator, scientists might soon be able to perform experiments on a realistic simulation of the mouse brain. In a new study, Stanford Medicine researchers and collaborators used an artificial intelligence model to build a "digital twin" of the part of the mouse brain that processes visual information.

Eating ultra-processed foods may rewire your brain’s hunger and reward circuits

High intake of ultra-processed foods is linked to adverse metabolic health and microstructural brain changes in regions that control appetite and reward. These effects occur both through obesity-related pathways and independently via inflammation and dyslipidemia.
