New peptide fragments teach the gut to tolerate food

https://www.news-medical.net/news/20260309/New-peptide-fragments-teach-the-gut-to-tolerate-food.aspx In little moments like when sipping coffee or licking an ice cream cone, it doesn't seem like your body is pulling off a biological miracle. But it is. That cookie is not you-yet when you put it in your mouth, your body is able to tolerate it and process it without any detriment to your health in a process called oral tolerance. How does the human body make that decision between tolerance and rejection?

Yale study identifies parent stress as an obesity risk factor

https://www.news-medical.net/news/20260309/The-Weight-Of-Stress-Helping-Parents-May-Protect-Children-From-Obesity.aspx In recent years, rates of childhood obesity have been rising, with the U.S. Centers for Disease Control estimating in 2024 that approximately one in five children and adolescents met the clinical definition of obese.

Redefining the "aging brain" through diverse data

https://www.news-medical.net/news/20260309/Redefining-the-aging-brain-through-diverse-data.aspx Age is more than just one number. While neuroscientists used to think of cognitive aging as a single trendline, they now realize that vast individual differences require a more predictive and personalized approach. As they uncover more factors that affect cognition over time, they are realizing that modeling the aging brain requires more diverse data than traditionally captured.

Understanding PIEZO2 mutations and sensory disorders

https://www.news-medical.net/news/20260309/Understanding-PIEZO2-mutations-and-sensory-disorders.aspx Every time we feel a gentle tap on the skin, specialized nerve cells convert that physical force into an electrical signal that the brain can interpret as touch. While scientists have long known that a protein called PIEZO2 acts as a key sensor for touch, it remained unclear why PIEZO2 is specialized for the localized mechanical forces experienced by sensory neurons, whereas its close relative PIEZO1 responds to broader mechanical stresses such as those generated when cells stretch, as occurs in blood vessels.

What are predictive markers for drug response and why do they matter?

https://www.news-medical.net/whitepaper/20260309/What-are-predictive-markers-for-drug-response-and-why-do-they-matter.aspx Most drugs and therapies introduced to date do not perform equally well for all patients, with significant differences in efficacy and safety among individuals. Frequently, a considerable proportion of patients simply do not respond, resulting in wasted therapy costs and no benefit to the patient.

Long-Term Effects of IVF on Women’s Health: Cancer Risk, Heart Disease, and Menopause

https://www.news-medical.net/health/Long-Term-Effects-of-IVF-on-Womene28099s-Health-Cancer-Risk-Heart-Disease-and-Menopause.aspx What does decades of research reveal about IVF and women’s long-term health? Evidence from large cohort studies and clinical guidelines suggests reassuring safety for most outcomes, while highlighting important nuances in reproductive aging, cancer risk, and psychological well-being.

How the Placenta Predicts Lifelong Health and Disease Risk

https://www.news-medical.net/health/How-the-Placenta-Predicts-Lifelong-Health-and-Disease-Risk.aspx The placenta plays a central role in fetal development by regulating nutrient transfer, hormonal signaling, and immune interactions, thereby shaping lifelong health outcomes. Evidence from developmental programming research indicates that placental structure and function, as well as environmental exposures during pregnancy, can predict cardiometabolic disease risk later in life.
