ByAlyson Krueger June 16, 2018 Three years ago Dyan deNapoli, a 57-year-old author and TED speaker who specializes in penguins, was given a 23andMe genetic testing kit for her birthday. Intrigued, she spit in the tube and sent the results to a lab in Burlington, N.C. About two months later she received a pie chart breaking down where her ancestors lived (99.4 percent of them were from Europe). What she was most giddy about, however, was a 41-page list of all the people who had done the test and were genetically related to her: 1,200 in all. (Customers can choose whether their information is shared with others.) “I had the names of everyone from my immediate family members to my first cousins, second cousins, third. Once I got past … [Read more...] about Are Genetic Testing Sites the New Social Networks?

BySteph Yin June 14, 2018 Two bacteria are sitting near free-floating DNA. Suddenly, one bacterium shoots out a long appendage, latches onto a DNA fragment and reels in its catch. It happens fast, but it’s clear: this organism had just gone fishing. Biologists at Indiana University recently captured this maneuver on camera for the first time. Their findings, published Monday in the journal Nature Microbiology, verify the existence of a harpoon-like mechanism that scientists have been piecing together for decades. The work also advances understanding of how bacteria take up DNA from their surroundings, which is called natural transformation. That process is key to the spread of … [Read more...] about Using Harpoon-Like Appendages, Bacteria ‘Fish’ for New DNA

McNeil Jr. May 24, 2018 Although there is optimism that the Ebola outbreak in central Africa can still be quickly contained, the fight is already becoming more complex, health experts said this week. Novel tactics — a new vaccine already in use, and new antibody or drug treatments that may be deployed — raise hopes that the outbreak will be quickly extinguished. But the treatments are unfamiliar to a wary and terrified population. There are now 58 confirmed or suspected victims in the Democratic Republic of Congo, of whom 27 have died, the World Health Organization said on Wednesday. Three cases were in health care workers. In one alarming development, three patients fled from an Ebola ward overseen by Doctors Without Borders in a hospital in Mbandaka, a city of more than one … [Read more...] about Doctors Test New Tactics Against Ebola in Central Africa

McNeil Jr. May 21, 2018 For the first time, the World Health Organization has published a list of diagnostic tests that it considers essential to every health care system in the world. The list, published Wednesday, is similar to the agency’s essential medicines list, which the W.H.O. launched in 1977. In its day, the medicines list was revolutionary because it was both a global guide to rational treatment regimens and because it fostered the idea that certain medicines were so important that they should be available to the whole world, regardless of price. The W.H.O. expert panel that created the diagnostics list hopes it will eventually be just as revolutionary. “I’m thrilled about it,” said, said Dr. Madhukar Pai, director of global health for McGill … [Read more...] about For First Time, W.H.O.

Sections SEARCH Skip to content Skip to site index Live Subscribe Log In Subscribe Log In Advertisement Supported by Living With Cancer BySusan Gubar May 17, 2018 When my cancer support group visited a research lab, the discussion of proteomics, fibroblasts and microRNAs made about as much sense to me as Lewis Carroll’s nonsense rhymes. Yet the meeting confirmed my suspicion that the gulf between patients and researchers needs to be bridged. Here’s how the gathering came about. One of my physicians is a mentor to Anirban Mitra, a researcher in ovarian cancer who works at Indiana University in my hometown. She suggested that Dr. Mitra meet with the members of my gynecological cancer support group. We invited Dr. Mitra to one of our get-togethers; however, he graciously offered to host a lunch at his lab in February, saying that our appearance would be a “huge motivator” for his team. During the visit, six of us … [Read more...] about The Jabberwocky in a Cancer Lab
