Recrystallized melted mixture of acetanalide, resorcinal and carbon tetra bromide, at 33x magnification. By John Hart of Hart3D Films in Boulder, Colorado. Won 13th place in the 2009 Nikon Small World Competition.
In a new study, zebrafish display signs of fear upon smelling sugar which are identical to their reactions to the pheromones released by other injured fish. Now scientists are speculating that this study could not only hint at the chemical composition of these pheromones, but also the origin of fear in fish and humans.
In the Sawmill Sink in Abaco, the water at a depth of 30 to 26 feet is pigmented by the bacteria. But the real danger lies in the hydrogen sulfide gas, which forces divers to hastily proceed through. Photo by Wes C. Skiles.

Illustrated here is a geologic map of Venus’s northern hemisphere, based off radar data from the Venera 15 and 16 orbiters, Pioneer Venus orbiter, and Earth-based radar telescopes. The colors indicate various features on the surface, such as plains in yellow and light green; mountains in purple, green and blue; and volcanoes in light red and pink.

22 years ago today, on April 24th, 1990, NASA launched its Hubble Space Telesecope. However, soon after launch, it is realized that the telescope’s mirror was ground incorrectly, and the flaw was unable to be corrected until December 1993, during a shuttle mission.

This video, by artist Isao Hashimoto, plots every nuclear bomb explosion from 1945 to 1998. Despite its relatively long duration of 14 minutes, this video is extremely effective. It’s both unsettling and sickening to see all the areas contaminated and resources wasted in the name of “domestic security.”
The Watson Table, named after James Watson and designed by Paul Loebach. This otherwise minimalist design has spiraling legs that are inspired by DNA structure.
