A major update to how obesity is defined could push U.S. obesity rates to nearly 70%, according to a large new study. The change comes from adding waist and body fat measurements to BMI, capturing peo...
The Champagne Cluster is a rare and beautiful example of two galaxy clusters smashing together. Its festive name comes from both its New Year’s Eve discovery and its bubbly appearance in space. Images...
New high-resolution images show that novae are anything but simple stellar fireworks. One exploded with multiple gas streams colliding almost immediately, while another shockingly delayed its eruption...
As we age, our immune system quietly loses its edge, and scientists have uncovered a surprising reason why. A protein called platelet factor 4 naturally declines over time, allowing blood stem cells t...
