New Brain Research Shows Dopamine Operates In a Completely Unexpected Way

Healthcare, Medicine / Ana Kiesse Zeleme

Instead of flooding the brain as once thought, dopamine is released in precise, ultra-rapid bursts that target specific neurons. This breakthrough overturns a century-old understanding of dopamine and could revolutionize treatments for conditions like ADHD and Parkinson’s disease. Researchers at the University of Colorado Anschutz Medical Campus discovered, while studying dopamine transmission, that the neurotransmitter […]

Robotic Coyotes Guard U.S. Airfields with Cyber-Charm and Force

Applied Science, Robotics / Eduardo Paulo

Why use an ordinary robot when you could deploy a robotic coyote? That’s the idea behind the U.S. Army Engineer Research and Development Center’s (ERDC) project—a cybernetic prairie predator designed to keep airfields free of dangerous wildlife. Airfields constantly face the challenge of birds and other wildlife, which can seriously endanger aircraft and operations. Birds

Humanoid Robots Could Ease Surgery Delays and Staff Shortages

Applied Science, Robotics / Valeriano Ndeyi

With crowded waiting rooms, rising doctor burnout, and growing surgical delays and cancellations, humanoid surgical robots present a potential solution—according to UC San Diego robotics expert Michael Yip in a Science Robotics perspective piece. Modern surgical robots are expensive, task-specific machines that require highly trained doctors to operate—making them difficult to scale. While AI and

Researchers Flag 4,200 Harmful Plastic Chemicals, Urge Safer Alternatives

Earth Science, Environmental Science / Jorge Paka

Nations are in the process of negotiating a global agreement aimed at ending plastic pollution and improving the safety and sustainability of plastics. A key concern in these talks is the presence of chemicals in plastics—ranging from food wrappers to car tires—that can seep into food, household environments, and ecosystems. Many of these plastic-related chemicals

Research Reveals Sleep Plays a Key Role in Protecting Heart Health for Menopausal Women

Healthcare, Medicine / Jorge Paka

During menopause, just 20% of women achieve ideal scores on the American Heart Association’s health-assessment tool, Life’s Essential 8 (LE8). Of its eight key health metrics, four—blood sugar, blood pressure, sleep quality, and nicotine use—play a major role in predicting future heart risks. Among them, sleep stands out as especially important for long-term cardiovascular health.
