    This is an interesting article about eukaryotes engaging in gene transfer with bacteria and archaea to survive in extreme environments.

  • interest surrounded one particular form of bacteria whose DNA was less than 86 percent similar to previously existing forms

      That's crazy. It's difficult for me to fathom the implications of that big of a difference in DNA because even the DNA of humans and apes is 95-98% similar.
  • Lake Vostok, which is believed to have been covered by ice for more than a million years but has kept its liquid state

      I wonder how that works, that the lake can remain liquid yet all the surrounding water is frozen as ice?
  • Exploring environments such as Lake Vostok allows scientists to discover what life forms can exist in the most extreme conditions

      Maybe this new bacteria could be similar to the domain Archaea since it can survive in such extreme conditions.

  • The possibility that the lake existed had first been suggested by a Soviet scientist in 1957

      The intelligence of scientists always astounds me. Even back in 1957 when technology was not as advanced as it is now they were able to make amazing discoveries such as this.

  • The researchers say the potentially looming Algaeworld might be avoided if those in the agricultural industry use "better management practices." Having the U.S. agree to a solid climate treaty probably wouldn't hurt, either.

    How do naive cells accomplish this microbial memory generation? It's all about the environment. People are constantly exposed to countless bacteria, fungi and viruses, everywhere all of the time. T cells might act like they're reacting to something they've seen before--maybe the bacteria's proteins look similar to that of a harmless bug, and the cell is fooled.

  • it was really a mini-pharmaceutical manufacturer, not the pharmacy it was licensed to be.
  • 1,200 different drugs
  • Apparently, all of this has been caused by contamination of drugs by a black mold called Exserohilum rostratum, which is common in the environment but almost unheard of as a cause of human disease.
  • For instance, on 13 occasions, they said, New England Compounding shipped out vials of drugs in three suspect lots before getting back results of their own tests confirming the drugs were sterile.
  • "indicated a failure ... to sterilize products for even the minimum amount of time necessary to ensure sterility,"
  • The firm's premises were not clean
  • medications were not labeled with individual patients' names
  • he may harbor a fungal infection that could kill him, there's no proof that he does — and there may never be.
  • many anxious patients are undergoing painful spinal taps and some are getting antifungal drugs that can damage the kidneys and liver.
  • The caution is warranted. This type of fungal infection can smolder for weeks and months before exploding into meningitis or causing massive strokes.
  • "It causes a quandary for the infectious disease doc to figure out, well, should this patient receive treatment at all?" O'Connell says. "Should they receive full-boat treatment, which would be an IV? Could they instead just be watched very closely with daily phone calls and visits to the office? We just don't know."
  • "Should we do lumbar punctures on those kinds of people so that we can anticipate those that are going to get symptomatic later and beat the fungus to it?" Schaffner wonders. "That is, initiate treatment much earlier, thus averting tissue damage, particularly those devastating strokes."
  • When to stop is also uncertain.
  • six months, maybe longer.
