“Alien Invasion” –99% of the Microbes Inside the Human Body are Unknown to Science

 

“There was something else, too – something weirder. Of all the non-human DNA fragments the team gathered, 99 percent of them failed to match anything in existing genetic databases the researchers examined. We found a whole new class of human-infecting ones that are closer to the animal class than to the previously known human ones, so quite divergent on the evolutionary scale.”

In 2013, the discovery of two giant viruses unlike anything seen before blurred the line between the viral and cellular world. Pandoraviruses are as big as bacteria, and contain genomes that are more complex than those found in some eukaryotic organisms (whose cells contain nuclei, unlike the two other kingdoms of living organisms, bacteria and archaea). Their strange amphora shape and enormous, atypical genome led scientists to wonder where they came from.

“Planetary Killer” –First Observation Ever of DNA Process that Evolves Into Drug-Resistant Bacteria

Scientists have made the first direct observation of a key step in the process that bacteria use to rapidly evolve new traits, including antibiotic resistance. Researchers recorded the first images of bacterial appendages — over 10,000 times thinner than human hair — as they stretched out to catch DNA. These DNA fragments can then be incorporated into bacteria’s own genome through a process called DNA uptake or “horizontal gene transfer.”
