The researchers found these bacterial molecules in brain samples from people with HIV, as well as people with no known infectious disease but who had undergone brain surgery

  So in immunocompromised individuals, as well as those whose brains have been exposed to the operating room - which as we learned in class, can still house bacteria despite all precautions taken.

If living bacteria help to maintain brain health in some way, disruptions to them, for example from antibiotics, could contribute to disease

  It will be interesting to see what they discover as they research this more. My guess it that the bacteria in the brain are both beneficial and harmful.

Dyes injected into the brain, meanwhile, tended not to appear in the body

  Wouldn't a shot into the brain kill you, or at least be very painful?

Last fall, for instance, researchers found male genetic material in the brains of women (who almost certainly were not born with it). Perhaps during pregnancy, the scientists suggested, cells from male fetuses had crossed the placenta and entered the women’s bodie

Scientists have discovered, for instance, that HIV hides inside white blood cells that enter the brain in order to look for pathogens; they call this the Trojan horse strategy

Bacteria Can Bypass Blood-Brain Barrier? It's a surprise to researchers who believed the brain-blood barrier created an impenetrable fortress. How are molecules from dirt getting into white matter-and what are they doing up there?

interest surrounded one particular form of bacteria whose DNA was less than 86 percent similar to previously existing forms
- Tiffany Arcand on 09 Mar 13
  
  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
- Tiffany Arcand on 09 Mar 13
  
  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
- Tiffany Arcand on 09 Mar 13
  
  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
- Tiffany Arcand on 09 Mar 13
  
  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.
