Temperature-controlled switch activates sperm, is key to fertility
Washington University in St. Louis

WashU Medicine researcher Polina Lishko, PhD, a BJC Investigator and professor of cell biology and physiology, has shown in mice that sperm have a temperature-controlled switch that changes their movements and is key to male fertility. The discovery sheds light on why mammals, including humans, have evolved to keep male reproductive organs cooler than their core body temperature.

“It’s Like They Have a Superpower”: Genetic Analysis of All-Women Extreme Divers Finds Changes Linked to Blood Pressure, Cold Tolerance
University of Utah Health

A new analysis of a group of all-women extreme divers off the coast of Korea has uncovered genetic differences that could help them survive the intense physiological stresses of free-diving—and could ultimately lead to better treatments for blood pressure disorders.

Copy Number Variant Analysis Improves Diagnostic Yield in a Diverse Pediatric Exome Sequencing Cohort
Children's Hospital Los Angeles

Highlight:Exome sequencing (ES) is commonly used to diagnose Mendelian disorders, which occur when pathogenic variant(s) in a gene are either inherited from one or both parents or are de novo. Examples of such disorders include cystic fibrosis and sickle cell anemia. However, ES is not the first choice for detecting copy number variants (CNVs), which are typically deletions or duplications of DNA segments.

Medicaid Unwinding Disrupted Kids’ and Young Adults’ Access to Chronic Disease Medicine
Michigan Medicine - University of Michigan

A new study suggests that medication interruptions among children and young adults taking medicine for chronic conditions happened more often in states that had the biggest drops in Medicaid enrollment during the recent “unwinding” process.

University of Utah Researchers Develop Explainable AI Toolkit to Predict Disease Before Symptoms Appear
University of Utah Health

The open-source software toolkit aims to predict whether individuals will develop progressive and chronic diseases years before symptoms appear. It can identify at-risk individuals with an accuracy of 85-99% and explain its outputs in ways that humans can understand.
