About 100 excited Chinese teenagers completed a five-hour tour of a space colony against a desolate backdrop not unlike the desert planet of Tatooine, the home world of Luke Skywalker. They were not on the set of Star Wars, but at a Chinese-built Mars simulation base in the barren, windswept hills of Gansu province. On Saturn's moon Titan, plentiful lakeside views, but with liquid methane

Scientists on Monday provided the most comprehensive look to date at one of the solar system's most exotic features: prime lakeside property in the northern polar region of Saturn's moon Titan - if you like lakes made of stuff like liquid methane. Using data obtained by NASA's Cassini spacecraft before that mission ended in 2017 with a deliberate plunge into Saturn, the scientists found that some of frigid Titan's lakes of liquid hydrocarbons in this region are surprisingly deep while others may be shallow and seasonal. Yale study revives cellular activity in pig brains hours after death

Yale University scientists have succeeded in restoring basic cellular activity in pigs' brains hours after their deaths in a finding that may one day lead to advances in treating human stroke and brain injuries, researchers reported on Wednesday. The scientists emphasized that their work did not even come close to reawakening consciousness in the disembodied pig brains. In fact the experiment was specifically designed to avoid such an outcome, however improbable.
