Apoptosis and Signal Transduction - Drew Berry - YouTube - dprjones

From Drew Berry's post here:

There is one project that I did solve the problem of creating random, brownian motion not look directed: My Apoptosis and Signal Transduction.

YouTube video:

This was an exploration of what a signal transduction would 'look like' if you were to follow the chain of molecular events along a pathway. I published that animation in Science Journal's STKE ( (Molecular Animation of Cell Death Mediated by the Fas Pathway, Sci. STKE 2007 (380).

The technique I used to make it work was difficult and very slow to pull off. The whole 4 min sequence took me around 12 months to research, construct and generate the imagery. I think visually it is my most successful piece at showing the mechanisms that emerge from randomly wandering, cytoplasmic molecules and membrane bound receptors.


Jake: Hanging out with a teenage Einstein - Morley Safer - CBS 60 Minutes

From 60 Minutes Overtime

(CBS News) 

Jake Barnett is one in 10 million. The Indianapolis 13-year-old has been acing college math and science courses since he was eight years old. Now Jake is a college sophomore taking honors classes in math and physics, while also doing scientific research and tutoring fellow students. No one could have predicted that Jake would even make it to college. At age two, Jake began to regress - he stopped speaking and making eye contact. The diagnosis: autism. Jake is proud of his autism. "That, I believe, is the reason why I am in college and I am so successful," he tells Morley Safer.

The following script is from "Jake" which aired on Jan. 15, 2012. Morley Safer is the correspondent. Katy Textor, producer.

Child prodigies have long been a source of great fascination. We wonder, "How can so much talent reside in such a young body, so much genius?" In a moment you'll meet Jake a 13-year-old math and science prodigy who is confident he may one day challenge some of the established theories of physics.

Rethinking "Out of Africa" - Christopher Stringer - Edge

I'm thinking a lot about species concepts as applied to humans, about the "Out of Africa" model, and also looking back into Africa itself. I think the idea that modern humans originated in Africa is still a sound concept. Behaviorally and physically, we began our story there, but I've come around to thinking that it wasn't a simple origin. Twenty years ago, I would have argued that our species evolved in one place, maybe in East Africa or South Africa. There was a period of time in just one place where a small population of humans became modern, physically and behaviourally. Isolated and perhaps stressed by climate change, this drove a rapid and punctuational origin for our species. Now I don’t think it was that simple, either within or outside of Africa.

CHRISTOPHER STRINGER is one of the world's foremost paleoanthropologists. He is a founder and most powerful advocate of the leading theory concerning our evolution: Recent African Origin or "Out of Africa". He has worked at The Natural History Museum, London since 1973,  is a Fellow of the Royal Society, and currently leads the large and successful Ancient Human Occupation of Britain project (AHOB),  His most recent book is The Origin of Our Species (titled Lone Survivors in the US).

Showing how our universe, solar system and planet Earth formed through natural and predictable processes.

Why do people laugh at creationists? #18

Another great video by ThunderfOOt

Part of a series of videos exposing the funny stupidity of creationists and why they deserve to be laughed at. In each case the creationist statements are shown to be outrageously stupid by even the most rudimentary knowledge of science.

In this episode it is shown how little respect creationists have for the western value of free speech. Repeatedly caught either censoring comments with zeal, or simply not allowing them. This trend goes across the board from the scientifically illiterate creationists, to the hub of the intelligent design movement, The Discovery Institute. Its further found that many of the earlier 'Why do people laugh at creationists' videos (particularly parts 3, 4 and 5, mainly containing material from the convicted fraudster and Young Earth Creationist, Kent Hovind), despite having an open comments section, have been targeted by creationist flagging campaigns.

Yup that's right, they had the latitude to present whatever argument they wanted, and what did they do? Embark on a flagging campaign. Evidently this is what some creationists think the strongest argument for creationism is.
