Scientists say they have finally assembled the full genetic blueprint for human life, adding the missing pieces to a puzzle nearly completed two decades ago. An international team described the first-ever sequencing of a complete human genome – the set of instructions to build and sustain a human being – in research published Thursday in the journal Science. The previous effort, celebrated across the world, was incomplete because DNA sequencing technologies of the day weren’t able to read certain parts of it. Even after updates, it was missing about 8% …

After spending two years being socially distanced in his home country of South Korea, Kim Hoe-jun booked a last-minute flight to Hawaii, where he had enjoyed his honeymoon six years ago, giving in to his craving for overseas travel. “I bought the ticket just a week ago, but it was rather a no-brainer. It felt like I was making up for those two years not being able to go abroad often as I used to before COVID,” he said, before boarding the plane from Incheon International Airport on Friday. Vaccinated …

Federal health officials are dropping the warning they have attached to cruising since the beginning of the pandemic, leaving it up to vacationers to decide whether they feel safe getting on a ship. Cruise-ship operators welcomed Wednesday’s announcement, which came as many people thought about summer vacation plans. An industry trade group said the move by the Centers for Disease Control and Prevention validated measures that ship owners have taken, including requiring crew members and most passengers to be vaccinated against the virus. The CDC removed the COVID-19 “cruise ship …

A batch of dome-shaped ice volcanoes that look unlike anything else known in our solar system and may still be active have been identified on Pluto using data from NASA’s New Horizons spacecraft, showing that this remote frigid world is more dynamic than previously known. Scientists said that these cryovolcanoes — numbering perhaps 10 or more — stand anywhere from 1 kilometer (six-tenths of a mile) to 7 kilometers (4-1/2 miles) tall. Unlike Earth volcanoes that spew gases and molten rock, this dwarf planet’s cryovolcanoes extrude large amounts of ice …
