...main advantage was that Gordon and his team now had the cutting-edge DNA-sequencing capability to scan and analyze all the genes contained in those bacteria. That meant researchers could determine not only which species of bacteria were present and in what proportions, but also which genes these bugs were actively using in different conditions. Before such genomic-analysis technology became available, researchers could study only the gut microbes (animal or human) that could be cultured outside their intestinal home - something that not all of the oxygen-shunning bugs were amenable to - but never the complete microbiota...
...tradition took on great power - in the past, the Pentagon took great pains to ensure the bodies of unknowns remained unidentified, even going so far as to destroy relevant documents about where bodies were discovered and with what, if any, personal effects. But with the advent of DNA testing in the 1980s and '90s, the tradition of burying an unknown soldier has begun to decline. Most soldiers around the world are now required to supply blood samples upon joining the military to ensure their bodies can be identified if they are slain in the line of duty. Although military personnel...
...fire left victims’ remains unscathed but damaged mementos placed by victims’ families on wooden benches in the chapel. The remains of unidentified victims of the 9/11 attacks are stored in the chapel while they await DNA identification and transfer to their permanent resting place at the 9/11 memorial, which is currently under construction...
...your life when you’re looking for connections.” Initiated this fall, Silk Road Connect employs a variety of tools—including workshops with the ensemble and partnerships with major institutions—to explore the effects of cross-cultural exchange. Students receive DNA testing sponsored by National Geographic to explore their ancestry, for example, and work with an existing gallery on the Silk Road in New York’s National History Museum.The cross-cultural exchange epitomized by the Silk Road Ensemble mirrors the daily life of American youth, in particular those living...
...their rush to loot the tomb, robbers severed the head from its body, and it is unknown today whether the head belonged to the governor or to his wife. But here again, the exhibition highlights archaeological advancement in relation to the object itself. A video explains how DNA testing is currently answering this century-old question...
