Scientists at Northwestern Medicine have developed a new genetic risk score that predicts who is most likely to experience irregular or dangerous heart rhythms. The test merges several types of genetic analysis into one powerful model, offering doctors a clearer way to spot risk early. Researchers believe this “genetic roadmap” could transform how conditions like AFib are detected and prevented. It may also help shape targeted therapies tailored to a person’s unique DNA.

Researchers have uncovered that SerpinB3, typically linked to severe cancers, is also a key player in natural wound healing. The protein drives skin cell movement and tissue rebuilding, especially when paired with next-generation biomaterial dressings. Its newfound role explains why cancer cells exploit it and opens the door to new wound-healing therapies.

People are more likely to believe lies when there’s the possibility of a reward. Neuroimaging shows that the brain shifts into reward or risk mode depending on whether the context involves a gain or a loss. Friends show synchronized brain activity that can predict successful deception. Social bonds and incentives can subtly warp how we judge honesty.

Ultra-processed foods, already known for their links to health problems in adults, are now shown to harm young adults too, disrupting blood sugar regulation long before illness appears. A four-year USC study following 85 participants found that even modest increases in UPF consumption drove up the risk of prediabetes and insulin resistance, two early markers that pave the way for type 2 diabetes.
