A new article describes a longer-lasting, 3D-printed, adhesive-free wearable capable of providing a more comprehensive picture of a user’s physiological state.

A new study reveals that a single gene plays a big role in how the liver stores energy, a process that’s critical for overall health and for managing diseases like type 2 diabetes. The research focuses on the PPP1R3B gene. This gene tells the liver how to handle energy: store it as glycogen (a form of sugar) or triglycerides (a type of fat).

A groundbreaking new study introduces an AI-powered smartphone app that noninvasively screens for anemia using a photo of a user’s fingernail. The study shows the app provides hemoglobin estimates comparable to traditional lab tests, with over 1.4 million tests conducted by 200,000+ users. An estimated 83 million Americans and more than 2 billion people globally are at high risk for anemia — populations that stand to benefit significantly from this accessible screening tool. The app offers a low-cost, scalable solution that enhances access, especially in underserved and remote communities, while enabling real-time health monitoring and earlier intervention.

An often-ignored type of cell in the brain plays a dynamic and surprisingly complex role in our ability to process information, according to new research.

A pioneering research study details how the hormone FGF21 (fibroblast growth factor 21) can reverse the effects of fatty liver disease in mice. The hormone works primarily by signaling the brain to improve liver function.

Engineers built E-BAR, a mobile robot designed to physically support the elderly and prevent them from falling as they move around their homes. E-BAR acts as a set of robotic handlebars that follows a person from behind, allowing them to walk independently or lean on the robot’s arms for support.

An innovative outbreak detection program that tracks disease-causing viruses in wastewater identified the measles virus in Houston samples collected in early January 2025, before cases were reported.

New research has uncovered how lipid-rich fluid in the abdomen, known as ascites, plays a central role in weakening the body’s immune response in advanced ovarian cancer. The findings offer new insights into immune suppression in ovarian cancer and open promising avenues for future immunotherapy approaches. Over 70% of patients with ovarian cancer are diagnosed at an advanced stage, often presenting with large volumes of ascites. This ascites fluid not only supports the spread of cancer throughout the abdominal cavity but also significantly impairs the body’s immune defenses. Understanding how ascites affects the immune system is important for developing better treatments that use the immune system to fight cancer.

Wild chimpanzees alter the meaning of single calls when embedding them into diverse call combinations, mirroring linguistic operations in human language. Human language, however, allows an infinite generation of meaning by combining phonemes into words and words into sentences. This contrasts with the very few meaningful combinations reported in animals, leaving the mystery of human language evolution unresolved.

Millions of kilometers of rivers around the world are carrying antibiotic pollution at levels high enough to promote drug resistance and harm aquatic life, a new study warns. The study estimated the scale of global river contamination from human antibiotics use. Researchers calculated that about 8,500 tons of antibiotics — nearly one-third of what people consume annually — end up in river systems around the world each year even after in many cases passing through wastewater systems.
