One Time America Thought About Nuking the Moon, and a Few Times Humans Smashed Things Into It Anyway

Posted on Categories Discover Magazine

The 1950s were a bizarre period in American history. An economic boom brought joy to a generation home from war, and also harbored a strange level of distrust, of enemies both internal and external, in a nation not quite at war, but not quite at peace either. Technology was advancing in leaps and bounds, and the Space Race between the United States and the Soviet Union was underway. To America's dismay, the Soviets were winning – at least at first. But before ...read more

Dinosaur Relative Antarctanax Lived In Antarctica After Biggest Mass Extinction

Posted on Categories Discover Magazine

A dinosaur relative about the size of an iguana, which lived at the bottom of the world 250 million years ago, is throwing paleontologists for a loop. Antarctanax shackletoni, named for explorer Ernest Shackleton, hints at unexpected biodiversity on the now-frozen continent of Antarctica. About 252 million years ago, the greatest mass extinction known walloped life on Earth. An estimated 90 percent of all living things perished. In the wake of this event, known as the end-Permian or Gre ...read more

How Scientists Are Using Ultrasound To Control Genes, Cells and More

Posted on Categories Discover Magazine

Most parents’ first glimpse of their children comes in ultrasound images taken months before birth. But ultrasound could soon offer much more than prenatal portraits. In the past few years, researchers have opened a new door for ultrasound, developing techniques that harness the familiar, safe and noninvasive sound waves to control genes, alter brain function and deliver drugs to targets with millimeter precision. The advance of what’s being termed sonogenetics offers a new twist on ...read more

Starfish Are Dying Out Fast Along America’s Pacific Coast

Posted on Categories Discover Magazine

Sea stars, also commonly called starfish, are among the most abundant animals along the U.S. West Coast. But now scientists say an epidemic spurred by warming ocean waters is decimating sunflower sea stars, a critical predator in kelp forests. The sea stars’ collapse could wipe out the shallow water ecosystems that provide a home for seals, sea otters and commercially important fish. “The epidemic was catastrophic and widespread,” said Drew Harvell, a marine ecologist at Corne ...read more

Scientists Gave This Robot Arm a ‘Self Image’ and Watched it Learn

Posted on Categories Discover Magazine

In The Matrix, Morpheus tells Neo that their digital appearance is based on their “residual self-image.” That is, the characters look how they imagine themselves to look, based on their own mental models of themselves. In the real world, scientists have been trying to teach robots that trick as well. That's because, unlike the warring machines of the matrix, a real-life robot with an accurate self-image might benefit humanity. It’d allow for faster programming and more accura ...read more
