Scientists offer a detailed look at the skeleton of an ancient predator that thrived in extreme conditions
Imagine a world on the brink of collapse: volcanic eruptions spewing toxic gases, oceans turning acidic, and up to 90% of Earth's species vanishing in the blink of an eye. This was the reality at the end of the Permian Period, around 252 million year.....»»
Engineers create a chip-based tractor beam for biological particles
MIT researchers have developed a miniature, chip-based "tractor beam," like the one that captures the Millennium Falcon in the film "Star Wars," that could someday help biologists and clinicians study DNA, classify cells, and investigate the mechanis.....»»
