Richard Cogdell - Bacterial Photosynthesis (MWV 069)

submitted by: MicrobeWorld
Richard Cogdell is the Director of the Institute for Molecular Cell and Systems Biology at the University of Glasglow, Scotland. Richard was led to a career in studying bacterial photosynthesis by a desire to learn and understand basic photosynthesis, he "wanted to know how natured worked." In 1995, Richard's research group, in collaboration with others, used protein crystallography to determine the three dimensional structure of a light-harvesting complex from the purple bacterium,...

LIGHT absolutely does NOT exist.

Light is only the electromagnetic waves of HEAT that hit our retinas and what only our BRAINS then define as Light.

MWV Episode 59 - Anne K. Jones - Cyanobacteria's Potential as a Fuel Product

submitted by: MicrobeWorld
In episode 59 of MicrobeWorld Video, filmed at the American Association for the Advancement of Science Meeting in Vancouver, BC Canada on February 17, 2012, Dr. Stan Maloy talks with Anne Jones, D. Phil., Assistant Professor, Department of Chemistry and Biochemistry, Center for Bioenergy and Photosynthesis, Arizona State University, about why her research into harvesting excess light energy has promising potential as an energy alternative. Anne explains why photosynthesis is an...

CHALK TALK: INFRARED

submitted by: nsf

Infrared can be divided into three separate categories – near, mid, and far, and even though we can’t see it, in some cases we can detect it. Many things, including people and planets, emit infrared. We also use it to transmit information via remote controls and video game consoles.

CHALK TALK: ELECTROMAGNETIC SPECTRUM

submitted by: nsf

The electromagnetic spectrum is the range of all possible wavelengths of energy, including the visible light that makes plants grow, and the infrared that your remote control uses to command your television. Wavelength decreases as frequency increases, so we can say that it is inversely proportional to both frequency and energy.

CHALK TALK: ELECTROMAGNETIC RADIATION

submitted by: nsf

Electromagnetic radiation (ER) is a form of energy, and it acts like a wave as it moves at the speed of light--it’s how energy from the sun reaches Earth. ER is classified by frequency—how many times the wave oscillates in a given amount of time.
