The William’s Dwarf Gecko (Lygodactylus williamsi), also known as the Electric Blue Gecko, is a small, critically endangered gecko found in the Kimboza Forest (in eastern Tanzania). The males are a more vibrant blue than the females, and females are often confused with juvenile or socially suppressed males. Both genders have a orange underbelly, though the colours of individuals vary with temperature and mood. Adults grow to between 5 to 8cm (not including the length of their tail).
Like all geckos from the genus’ Lygodactylus and Phelsuma, these little geckos are diurnal. This species is also bold, active, social, and males are territorial. Social gestures include lateral flattening, puffing out of the throat patch, head shaking and head bobbing, and tail-wagging.

SEM image (9,379x magnification) of a Zebrafish neuromast taken near the ear. Katie Kindt false-colored the image taken by Greg Baty.
Katie’s main interest in taking the SEM image was to examine the stereocilia and correlate the result with confocal studies that were performed while the zebra fish was alive. Katie and Gabe Finch at OHSU had a difficult time preparing the fish for SEM, due to the variability in a rapidly growing fish that is three days old. It took an interdisciplinary team effort to produce an image of this quality on a high vacuum XL30 Sirion.

Chalk under a microscope.
“Chalk is composed of extremely small white globules. They look, up close, like snowballs made from brittle paper plates. Those plates, it turns out, are part of ancient skeletons that once belonged to roundish little critters that lived and floated in the sea, captured a little sunshine and carbon, then died and sank to the bottom… Scientists call these ancient plates ‘coccoliths.’”
