When Apollo 17 astronauts Gene Cernan and Harrison Schmitt left the lunar surface in 1972 their iconic moon buggy remained behind . But since Neil Armstrong first set foot on the moon in 1969 conspiracy theorists have speculated the landings were faked . Now a private moon mission is gearing up to take place, led by a rover manufactured by German car maker Audi. The Audi Lunar Quattro can hit a top speed of 2.2mph and the team behind it have secured a launch contract to send it to the moon. ..>> view originalBig-city mayors discuss emissions targets to limit the worst effects of climate change
Bangkok and Miami could be underwater in a matter of decades if sea levels keep rising. Cape Town could see severe food shortages because of drought.In Mexico City, which gets so smoggy in the spring that parents keep their children indoors, hotter temperatures could make the pollution even worse. Global warming poses an existential threat to many of the world’s cities. But cities are responsible for more than 70% of the carbon dioxide and other greenhouse gases that trap heat in the atmosph..>> view originalHallucinogen Eases Depression in Cancer Patients, Studies Find
In both trials, the intensity of the mystical experience described by patients correlated with the degree to which their depression and anxiety decreased. The studies, by researchers at New York University, with 29 patients, and at Johns Hopkins University, with 51, were released concurrently in The Journal of Psychopharmacology. They proceeded after arduous review by regulators and are the largest and most meticulous among a handful of trials to explore the possible therapeutic benefit of psil..>> view originalWorried Scientists Urge Trump to Respect Their Work
More than 2,300 American scientists, including 22 Nobel Prize winners, issued an open letter to President-elect Donald Trump and Congress Wednesday, urging them to respect science. They are especially worried about government interference in their work and about policies that could reject scientific fact — notably climate science.

A model of Lucy, one of the most famous human ancestors. (Michael Stravato/Associated Press) In Ethiopia, she is known as “Dinkinesh” — Amharic for “you are marvelous.” It's an apt name for one of the most complete ancient hominid skeletons ever found, an assemblage of fossilized bones that has given scientists unprecedented insight into the history of humanity. You probably know her as Lucy. Discovered in 1974, wedged into a gully in Ethiopia's Awash Valley, the delicate, diminutive skeleto..>> view originalGravitational-Wave Detector Resumes Hunt for Space-Time Ripples
The experiment that made the first direct detection of gravitational waves is once again hunting for these space-time ripples. The Laser Interferometer Gravitational-wave Observatory (LIGO) stopped collecting data in January for a scheduled period of upgrades to its two detectors, located in Hanford, Washington, and Livingston, Louisiana. Now, the machines are back on, looking for gravitational waves coming from distant cosmic sources. The LIGO collaboration announced the first direct..>> view originalSaturn mission approaches tour finale
