Scientists publish the first complete human genome

Scientists on Thursday published the first complete human genome, filling in gaps remaining after previous efforts while offering new promise in the search for clues regarding disease-causing mutations and genetic variation among the world's 7.9 billion people. Researchers in 2003 unveiled what was then billed as the complete sequence of the human genome. But about 8% of it had not been fully deciphered, mainly because it consisted of highly repetitive chunks of DNA that were difficult to mesh with the rest.

Vaccination after COVID improves immunity; ivermectin fails in major trial

The following is a summary of some recent studies on COVID-19. They include research that warrants further study to corroborate the findings and that has yet to be certified by peer review. Vaccination after COVID-19 improves immunity

NASA's SOFIA observatory studies neighboring galaxy from Chile

An airplane-borne telescope has flown high above Chile at night this month to observe a sliver of the universe as scientists aim to gain a better understanding of how stars are born. The U.S. space agency NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA), a state-of-the-art Boeing 747 fitted with a telescope able to observe the entire infrared spectrum, arrived in Chile this month, marking its first visit to South America.

Hubble telescope spots Earendel, the most distant star on record

Using NASA's Hubble Space Telescope, scientists have discovered the most distant individual star on record, a bright behemoth they nicknamed Earendel - Old English for "morning star" - because it existed during the dawn of the universe. Researchers said the star, very hot and blue in color, was estimated at 50 to 100 times the mass of our sun, while being millions of times brighter. Its light traveled for 12.9 billion years before reaching Earth, meaning that the star existed when the universe was just 7 percent of its current age.
