Collection of Science Photos

Below are several examples from this interesting collection of science photos:

Human tongue:
A high energy beam scanner, called a scanning electron micrograph, was used to capture this image, which shows the surface of a human tongue. The protruding objects, called filiform papillae, can sense pressure. The flaky appearance of the papillae results from the fact that they are constantly shedding their skin to increase sensitivity.



Blood clot:
This electron micrograph of a blood clot shows an exceptional level of detail, part of the Wellcome Images collection. For this image, the photograph was enhanced to show detail and color, but in the center of the image, there is a clearly identifiable white blood cell surrounded by a blood clot.



Green Sea Slug:
This green sea slug – found on the East coast of the US and Canada -- has an interesting ability: It can synthesize the green pigment chemical chlorophyll like a plant.



Pond Scum:
Researchers are discovering some amazing creatures in the pond scum. In this photo, the single-celled Plagiopyla looks like a smiling face or Easter Island statues.



Weaver Ants:
Weaver ants (Oecophylla sp.) put the finishing touches on their nests in Buton Island, off the southeast peninsula of Sulawesi, Indonesia. As their name implies, they use living plants to "weave" leaves together to construct their nests, which they vigorously protect. Silk produced only by the larvae helps hold the nest together.
