Value-based care redirects health systems from counting how many services are provided to concentrating on the outcomes that genuinely matter to patients, built on a straightforward idea: compensation should reward value rather than volume, a shift that influences clinical choices, payment structures, evaluation methods, and patient involvement while helping curb unnecessary procedures and enhance quality, equity, and affordability.What value-based care meansValue-based care seeks to optimize health outcomes for every dollar invested by:Measuring outcomes: emphasizing clinical results, functional abilities, patient-reported measures (PROMs), and overall experience instead of tallying visits or procedures.Aligning payment: implementing incentives that promote prevention, coordinated care, and demonstrable…

A more secure direction ahead for lithium-ion batteriesBold innovation in battery chemistry is reshaping how safety and performance can coexist. A new electrolyte design developed by researchers in Hong Kong offers a promising way to reduce fire risks without disrupting how today’s lithium-ion batteries are made.Lithium-ion batteries have become an invisible backbone of modern life. They power smartphones, laptops, electric vehicles, e-bikes, medical devices and countless tools that shape daily routines. Despite their efficiency and reliability, these batteries carry an inherent risk that has become increasingly visible as their use has expanded. Fires linked to lithium-ion batteries, while statistically rare,…

Unprecedented dinosaur trackways unveiled in Bolivia’s Carreras PampasOver 16,000 fossilized footprints unearthed in Bolivia present a vivid glimpse into the movements of theropod dinosaurs from over 100 million years ago. These tracks, preserved along an ancient shoreline, offer rare insights into how these predators navigated their environment during the late Cretaceous period.The Carreras Pampas site, situated within Bolivia’s Torotoro National Park, has revealed an extraordinary concentration of theropod footprints, with scientists recently identifying 16,600 impressions. This number exceeds any previously recorded tracksite in terms of sheer volume. The preserved tracks cover approximately 80,570 square feet (7,485 square meters) and include…

Astronomers capture new images of interstellar comet 3I/ATLAS approaching EarthNew insights into comet 3I/ATLAS highlight its distinctive composition and active tails as it approaches its nearest point to Earth this month. The interstellar traveler, hailing from outside our solar system, has captivated scientists' attention since it was first identified in July 2025.Comet 3I/ATLAS is only the third interstellar object ever detected traveling through our solar system, making every observation crucial for understanding its trajectory, composition, and behavior. Both the Hubble Space Telescope and the European Space Agency’s Jupiter Icy Moons Explorer (Juice) mission have captured detailed images of the comet,…

NASA is preparing to launch twin spacecraft on a novel, winding journey to Mars, aiming to unlock the secrets behind the planet’s lost atmosphere.The mission, named EscaPADE—short for Escape and Plasma Acceleration Dynamics Explorers—plans to undertake an unprecedented orbital trajectory to study how Mars gradually lost its atmosphere billions of years ago. Spearheaded by the University of California, Berkeley, and supported by aerospace companies Advanced Space and Rocket Lab, the project represents a bold experiment in low-cost planetary exploration. Unlike typical Mars missions that rely on direct paths during tight launch windows, EscaPADE will follow a unique “launch-and-loiter” strategy, allowing…
