每日英語跟讀 Ep.K359: About medicine - 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.
A consortium of scientists resolved that in research published in the journal Science. The work was initially made public last year before its formal peer review process.
The consortium’s full version is composed of 3.055 billion base pairs, the units from which chromosomes and our genes are built, and 19,969 genes that encode proteins.
‘You inhaled it’: Man inhales drill bit during dental visit 「你把它吸入了」：男子看牙醫時吸入鑽頭
A routine trip to the dentist was anything but normal — after an Illinois man inhaled the dentist’s drill bit and had to go to the hospital to get it removed last month.
Tom Jozsi, 60, told WISN-TV that he was at the dentist getting his tooth filled when he was told he swallowed a tool.
“I didn’t really even feel it going down. All I felt was a cough. When they did the CT scan they realized, ‘You didn’t swallow it. You inhaled it,’” he said. Doctors believe that Jozsi inhaled just before he coughed, sending the 1-inch bit deep into Jozsi’s lung.
Dr. Abdul Alraiyes decided to try a newer device to remove the object — one that’s designed for early detection of cancer.
Video of the scan shows the medical team was able to navigate the narrow airways, reach the drill piece and pull it out without harming Jozsi.
