So this is what I've been up to - cruising on a research ship in the Pacific ocean near Tonga, helping operate a robotic submersible collecting hydrothermal vent samples....here's our research blog!

Hello interwebs! I'm raising money for an upcoming school trip to Costa Rica. I know I wouldn't care about donating unless there were some goodies attached so I'm offering lots of rewards! By helping me pay for this trip you're helping me graduate next year! Stay tuned, I'm hoping to get some crafty endeavors underway soon.

The World Health Organization has released a report, detailing some alarming findings in regard to antibiotic resistance.

"The report makes a clear case that resistance to common bacteria has reached alarming levels in many parts of the world and that in some settings, few, if any, of the available treatments options remain effective for common infections."

PNNL's 2014 Science as Art contest launches Monday, April 21 ... and YOU will determine our winners. Visit and follow our Facebook page (http://www.facebook.com/PNNLgov) where your votes will be cast by "liking" our researchers' science images. Voting starts Monday and closes at noon PDT on Friday, April 25th. 

The more voters, the better … so please SHARE this post with friends and colleagues! 

Shown here is a Science as Art image from our 2011 contest: Lepidote scales that impart Russian Olive leaf surfaces with a silvery sheen. PNNL researchers captured this image using a Scanning Electron Microscope. To see entries from recent years, visit our Flickr site at https://www.flickr.com/photos/pnnl/

This week in Science, researchers show that myelin distribution is diversified, and signature myelin profiles appear in different neocortical layers. Myelin encapsulates the axons of neurons and is crucial to normal function in the mammalian nervous system. It allows electrical impulses to travel quickly and efficiently by reducing sodium leakage and utilizing saltatory conduction. Action potentials hop along Nodes of Ranvier, where myelin is missing from the axon and voltage-gated ion channels are present, in order to regenerate the action potential at the next node. The degradation of myelin sheath is a trademark of many neurodegenerative disorders such as multiple sclerosis. Current research is focused on understanding the structure of myelin, and big projects focus on the regeneration of myelin (it does not regenerate, hence numerous myelin-based disorders).

This is a great read about disease transmission and safety in laboratories. Some may argue that some pathogens shouldn't be studied and modified because of the danger involved but I think it calls attention to the need for improved research on isolation and detection techniques.

Here are the final pictures I took on the SEM and they highlight exactly what I was looking for! Note how much longer the cells grown at 60C are from the 45C and 50C. This bug changes its length at different growing conditions.  #science   #microscopy
