USC scientists discover how to create a never-ending supply of cancer-fighting cells

Scientists at the University of Southern California (USC) have discovered a way to produce a potentially renewable supply of cancer-fighting immune cells, opening a promising new direction for cancer treatment. By working with immature cells that can develop into powerful immune defenders, the researchers have created a system capable of…

The uranium cubes that exposed Nazi Germany’s nuclear failure

During World War II, the United States raced to develop the atomic bomb partly out of fear that Nazi Germany might build one first. But how close did Germany actually come to achieving that goal? A new scientific investigation suggests the Nazi nuclear program was much further from success than…

Yale scientists discover how stress changes the brain to make memories stronger

Stress does more than influence how we feel. It can also change what we remember, particularly when an experience is emotionally intense or personally meaningful. Scientists have long known that cortisol, a hormone released during stressful situations, can strengthen emotional memories. What has been less clear is exactly how this…

Astronomers discover a strange universal rule behind black hole eruptions

Astronomers have uncovered a surprising rule that appears to determine when black holes unleash powerful jets of material into space. Even though black holes can differ in mass by millions of times, researchers found that they seem to follow the same fundamental pattern when producing these enormous cosmic outflows. The…

Scientists discover a plastic-eating “Pac-Man” enzyme with a surprising secret

Plastic pollution is one of the world’s most persistent environmental problems. Vast amounts of discarded plastic accumulate in the oceans, sometimes forming enormous garbage patches that threaten marine life. Most conventional plastics break down extremely slowly because microorganisms struggle to digest the synthetic polymers from which they are made. Instead…
