Photographs from a Ross’s Goose (Chen rossii) found dead in Kansas, US. (A) Petechial hemorrhages along the coronary groove of the epicardium (arrowheads) and military pinpoint tan foci on the capsular surface of the liver (arrows). (B) Abundant creamy stringy yellow mucoid material (*) fills the lumen of the intestine.

Photomicrographs from a Ross’s Goose (Chen rossii) found dead in Kansas, US. (A) Multifocally, there are hemorrhages (arrowheads) admixed with bacteria (arrows) in the adipose tissue along the coronary groove of the heart. H&E stain. (B) Necrotic hepatocytes (*) and bacteria (arrows) are present in the liver. H&E stain.

Vegetation grows abundantly on a once-flooded region of the Santa Ynez River. Located 5 ft adjacent from this picture is the actual flowing region of the stream. It is impressive to see the abrupt change in vegetation near stream environments.

What is a meniscus?
A meniscus is a curve in the surface of a molecular substance (water, of course) when it touches another material. With water, you can think of it as when water sticks to the inside of a glass.

It seems to defy the laws of physics, but a paper clip made of steel can indeed float on the water surface. The high surface tension helps the paper clip - with much higher density - float on the water.
