i do! i work in the blood bank of one of the local hospitals. i also go to grad school for biology.
and thanks :)
paused the latest “emma approved” episode.
came back to the computer to find this awesome look between emma and knightley. :)
After taking an in-depth look at the basic biology of a fungus that is decimating bat colonies as it spreads across the U.S., researchers report that they can find little that might stop the organism from spreading further and persisting indefinitely in bat caves.
The aptly named fungus Pseudogymnoascus (Geomyces) destructans causes white-nose syndrome in bats. The infection strikes bats during their winter hibernation, leaving them weakened and susceptible to starvation and secondary infections. The fungus, believed to have originated in Europe, was first seen in New York in the winter of 2006-2007, and now afflicts bats in more than two dozen states. According to the U.S. Fish and Wildlife Service, P. destructans has killed more than 5.5 million bats in the U.S. and Canada.

The beating of flagella is one of the basic principles of movement in the cellular cosmos. However, up to now, scientists were unsure as to how the movements of several of these small cellular appendages are synchronised. Dresden-based researchers from the Max Planck Institute of Molecular Cell Biology and Genetics and the MPI for the Physics of Complex Systems have now succeeded in demonstrating how the green alga Chlamydomonas synchronises the movements of its two flagella using a resourceful rocking movement.
To do this, the researchers started by developing a theoretical model which they were then able to substantiate in experiments with the microscopic breaststroke swimmers: when the two flagella lose their rhythm, the cell begins to rock. This causes the swimming movements to slow down or accelerate. The resulting synchronisation mechanism is based solely on the coupling of the two movements of the body and the flagella; no special sensors or chemical signals are needed.

((i was really hoping this article would have a .gif that went with it..))
Don’t tell me this is not touching…
can i get the book on problem bacteria? :-/
just an average day in the lab :)
