Science News Roundup: Son calls father's pig-heart transplant a miracle of science; NASA begins process of bringing new space telescope into focus and more

Data obtained by NASA's Kepler space telescope before it was retired in 2018 indicated the presence of a moon 2.6 times the diameter of Earth orbiting a Jupiter-sized gas giant about 5,700 light-years away from our solar system in the direction of the Cygnus and Lyra constellations, scientists said on Thursday. Polish scientists find gene that doubles risk of serious COVID Polish scientists have found a gene that they say more than doubles the risk of becoming severely ill with COVID-19, a discovery they hope could help doctors identify people who are most at risk from the disease.

Following is a summary of current science news briefs.

Son calls father's pig-heart transplant a miracle of science

The son of a transplant recipient who was implanted with a genetically modified pig heart in a first-of-its-kind surgery, called his father's procedure "a miracle." The surgery, performed by a team at the University of Maryland Medicine on Jan. 7, is among the first to demonstrate the feasibility of a pig-to-human heart transplant, a field made possible by new gene editing tools.

NASA begins process of bringing new space telescope into focus

NASA on Wednesday embarked on a months-long, painstaking process of bringing its newly launched James Webb Space Telescope into focus, a task due for completion in time for the revolutionary eye in the sky to begin peering into the cosmos by early summer. Mission control engineers at NASA's Goddard Space Flight Center in Greenbelt, Maryland, began by sending their initial commands to tiny motors called actuators that slowly position and fine-tune the telescope's principal mirror.

Older date for Ethiopian fossils sheds light on rise of Homo sapiens

Volcanic ash left over from a huge ancient eruption has helped scientists determine that important early Homo sapiens fossils found in Ethiopia in 1967 are older than previously believed, providing fresh insight into the dawn of our species. Researchers said on Wednesday they used the geochemical fingerprints of a thick layer of ash found above the sediments containing the fossils to ascertain that it resulted from an eruption that spewed volcanic fallout over a wide swathe of Ethiopia roughly 233,000 years ago.

Second alien moon identified is much like the first: big and strange

For only the second time, astronomers have detected what appears to be a moon orbiting a planet in another solar system. Just like the first time, this one has traits suggesting that such moons may differ greatly from those populating our solar system. Data obtained by NASA's Kepler space telescope before it was retired in 2018 indicated the presence of a moon 2.6 times the diameter of Earth orbiting a Jupiter-sized gas giant about 5,700 light-years away from our solar system in the direction of the Cygnus and Lyra constellations, scientists said on Thursday.

Polish scientists find gene that doubles risk of serious COVID

Polish scientists have found a gene that they say more than doubles the risk of becoming severely ill with COVID-19, a discovery they hope could help doctors identify people who are most at risk from the disease. With vaccine hesitancy a major factor behind high coronavirus death rates in central and eastern Europe, researchers hope that identifying those at greatest risk will encourage them to get a shot and give them access to more intensive treatment options in case of an infection.
