In most cases, these spherically shaped bacteria stay out of trouble. But that’s only in most cases. When presented with open wounds, scrapes, and scratches, S. aureus can invade and infect the body, and with serious consequences. In the skin, staph infections can cause boils, blisters, and inflammation. In the blood, t ...read more

A meteorite that struck northwestern Scotland about a billion years ago may have collided 200 million years later than initially believed. New research from Curtin University in Australia analyzed tiny crystals left behind by the impact and found that they were younger than previously thought. This new information could change what science knows about Scotland’s rich geological history and the general understanding of how non-marine life evolved on Earth. Scotland’s Meteorite Strike Along ...read more
The far side of the moon has a drier mantle than researchers previously believed, giving scientists more insight into its water content and the way that the moon has evolved.“Water abundance is crucial for understanding the origin and subsequent evolution process of the moon,” says Sen Hu, an astrophysicist with the Institute of Geology and Geophysics of the Chinese Academy of Sciences.A better understanding of the moon’s water content — though minimal — may also point to potential res ...read more
