The polymerase chain reaction (PCR) song by Scientists for Better PCR

This is “The PCR Song” by “Scientists for a Better PCR”. It was done by the good folks at Bio-Rad to promote their 1000 Series Thermal Cyclers (a pcr machine). This is probably the best geek ad  and will provide laughs to all (especially those who remember when pcr meant dipping your samples in individual waters baths for two or more hours). Enjoy! –

Amazing 3D simulations of science in silico

Computer simulations and visualizations are performing the thought experiments of the 21st century and pushing the limits of human vision and imagination. In silico simulations are probably future of many complex biological experiments.

Cancer Fighting Technology for Brain Tumors

Trilogy Stereotactic Radiation Therapy to treat brain tumors. Trilogy precisely pinpoints the exact location of the cancer and treats it with a highly accurate beam of radiation.

Wonderful Medical Animation Reel

This 3D animation shows various surgical (mostly orthopedic) medical procedures performed to fix the problems in our bodies. Very nice done. 

Why can’t we grow new body parts?

This is an excellent video by Alan Russell, who studies regenerative medicine.

Regenerative medicine is a breakthrough way of thinking about disease and injury by helping the body to rebuild itself. He shows how engineered tissue that “speaks the body’s language” has helped a man regrow his lost fingertip, how stem cells can rebuild damaged heart muscle, and how cell therapy can regenerate the skin of burned soldiers.

This presentation is hosted at TED (Technology, Entertainment, Design). It is a very nice site that hosts talks by world’s greatest thinkers and doers.

Super 3D animation that shows the mode of action of an HIV drug

In this cool animation the mode of action of a novel HIV drug, a protease inhibitor, is explained. Protease inhibitors revolutionized treatment of HIV infection by enabling drug combinations with inhibitors of another HIV enzyme the reverse transcription. Thus, this made it more difficult for virus to develop multiple mutations simultaneously to escape the effects of a single drug.

Amazing chemistry and rational drug design is involved in creating these new drugs.
