Your own personal scanning electron microscope - Astronomy.com blog - 0 views

  •  
    "If you send in a sample of something and a form, they'll run it through their scanning electron microscope for free, and post the images online. Their site explaining the process outlines the 5 steps to make it happen: find a sample, fill out a form, send them to ASPEX, wait for them to scan it (usually about 2 weeks), and look at it online."

    To give everybody an opportunity to make his own "hands on" experience with the Nanoworld we provide all information to build up and use some of the standard equipment of this fascinating field of science, starting with the Nobel-Prize-Winner of 1986: the Scanning-Tunneling-Microscope (STM).

YouTube - Bill Nye - Greatest Discoveries - 2: Biology - 0 views

  •  
    Join Bill Nye as he delves into the Greatest Discoveries in Biology. This program explains how the early use of microscopes and Anton Van Leeuwenhock's accidental discovery set the stage for studying microorganisms. It explores 19th century research breakthroughs and covers cell division, sex cell division, and cell differentiation. Learn how the discovery of mitochondria has helped us understand reproduction, ancestral lines, and cancer; how cells convert sugars, fats, and proteins into energy in the Krebs Cycle; and how they communicate through neurotransmitters and hormones. Explore the process of photosynthesis and how the discovery of the ecosystem process bridged biology with physics, chemistry, and other fields of science that describe the environment.

Enceladus up close - The Big Picture - Boston.com - 0 views

  •  
    Saturn's tiny, icy moon Enceladus has recently been visited by NASA's Cassini orbiter on several very close approaches - once coming within a mere 25 kilometers (15 miles) of the surface. Scientists are learning a great deal about this curious little moon. Only about 500 kilometers wide (310 miles), it is very active, emitting internal heat, churning its surface, and - through cryovolcanism - ejecting masses of microscopic ice particles into Saturnian orbit.
