Study shows how a potato-based diet changed the genetics of Andean ​people

Indigenous people in the Andes domesticated the potato - a great source of ​starch, vitamins, minerals and fiber - 6,000 to 10,000 years ago, ‌making ​this tuber a central part of their diet. These people then experienced genetic adaptations beneficial for such a diet that are still seen in their descendants living in Peru. New genomic research documents how these descendants - speakers of the Quechua language of the once-great Inca ‌Empire - underwent fortification involving a gene called AMY1 that is involved in starch digestion, a function useful for people with a potato-centric diet.

Trump releases government UFO files, ‌more expected

At the order of U.S. President Donald Trump, the Defense Department on Friday released dozens of previously classified files on alleged UFO sightings to provide what it called "unprecedented transparency" to the American people, though analysts said many of the documents had already been made public. The disclosure of documents, photos and videos of "unidentified anomalous phenomena" will be followed by future releases as more materials are declassified, the Defense Department said in ⁠a statement.

Astronomers ​get the best look yet at the ⁠surface of an exoplanet

Astronomers have gotten their clearest look yet at the surface of an exoplanet - a planet beyond our solar system - thanks to NASA's James Webb Space Telescope. Webb gathered data on a rocky exoplanet with a ⁠diameter about 30% larger than Earth that indicates it is a desolate and airless world whose surface may resemble that of Mercury, our solar system's innermost planet. Its lack of a discernible ​atmosphere and its extreme temperatures - fiercely hot on one side and frigid on the other - seem to render it uninhabitable.

David Attenborough turns 100, 'overwhelmed' by birthday wishes
