Not much else to comment on here, except that he seems to have excellent oral hygiene for a chainsaw-wielding maniac.A big man with the chainsaw and the gaping wound on his face jumps out from around the corner and growls. You leap backward and scream, your heart pounding in your ears. You’re ready to either take that power tool and teach him a lesson or to run like the kid from […]

5:30 PM | Autocatalytic Network: A Step Closer To Creating Artificial Living Systems
How did life originate? And can scientists create life? These questions have always occupied philosophers and scientists interested in the origin of life, and they impact technology of the future also. If we can create artificial living systems, we may not only understand the origin of life - we can also revolutionize the future of technology. Protocells are the simplest, most primitive living systems, you can think of. The oldest ancestor of life on Earth was a protocell, and when we see, […]

2:00 PM | Richard Dawkins and Nightwish
October 2012, I got to see Nightwish at a small venue in OKC. 1– This was one of the first nights Floor Jansen was officially the New Singer for Nightwish. She blew me away. 2– This was a *tiny* venue. Nightwish fills huge stadiums and auditoriums all over the world, but OKC? Teeny venue. And that…

This is a new kind of Tale for me. The rock'n'roll's turned way up, and every couple sentences I have to stop typing to twirl a blue hound dog, a bear holding an umbrella, a Flying Spaghetti Monster, and other oddities that I strung up to hypnotize this little guy into letting me type one thought at a time:The thing that needs to be hypnotized.Or the three wise monkeys say: The thing that makes it impossible to create or to dwell on the negative.

2:30 PM | Apoptosis Evolution: Cellular Self-destruction Has Been Around Almost As Long As Cells Have
It seems counter-intuitive that in order to survive best as a species, not everything can live forever, but some cells in our bodies are fated to die, and a Mission Impossible-style auto-destruct program insures they do. This elaborate cell death program, known as apoptosis, got a little more insight with a study on the evolution of caspase-8, a key cell death initiator molecule that was first identified in humans. By performing the most extensive evolutionary analysis of the Casp8 protein […]

Because epigenetics.” What are agent based […]

Le scandale n'attend pas : elle demande à la femme d'enlever son voile, puis ameute des policiers pour la faire obtempérer. Ceux-ci ne donnent pas suite à sa requête, la jugeant […]
