Curing cancer

Leukemia cells
Today I hung out with a good friend of mine who transferred from the Evolutionary Biology department at the University of Colorado to University of Sheffield in England.  While on a walk, he mentioned the latest news from the biology grapevine: researchers at Memorial Sloan-Kettering in NY have developed a new treatment for a certain type of leukemia, genetically modifying patients' own T-cells to attack the cancer.  Pretty impressive stuff, and seems like it could be quite a breakthrough for cancer research.  Check out a good summary article here.  And remember to hang out with your friends in other disciplines -- you never know what you'll learn from them!

Bacterial close-ups

When I was doing my master's research on the ecology of speciation in Bacillus subtilis - B. licheniformis, we had an undergrad working in the lab who took some of my plates and ran them through an electron microscope to see what the bacterial colonies looked like.  Here is one of the photos he took.

I was reminded of this photo from this National Geographic piece, showing lots of different bacterial species through an eletron microscope.  Check it out.
