Incredibly important and subtle point about gender and evolutionary biology
by Vinay Gupta • August 21, 2007 • Science • 0 Comments
This is a major eye-opener. The punchline: looks like about 2/3rd of the ancestors of the current human race were female, because a lot of men died without ever reproducing. Impacts for our understanding of our own genetic heritage? Huge.

At a certain point, the weight of the batteries required to provide the energy to operate the arm for a reasonable period becomes a problem. It was the poor power-to-weight ratio of the batteries that drove Goldfarb to look for alternatives in 2000 while he was working on a previous exoskeleton project for DARPA. He [...]

Saving the Internet with hate. It’s a riff on protocol, reputation, process, people and code. And it works, I think, on levels that nothing else I’ve seen might. A++ – I hope it’s bigger than bittorrent.

Reason on gender inequality in pay. June O’Neill, an economist at Baruch College and former director of the Congressional Budget Office, has uncovered something that debunks the discrimination thesis. Take out the effects of marriage and child-rearing, and the difference between the genders suddenly vanishes. “For men and women who never marry and never have [...]

Mars has warmed about as much as the Earth has over the same period Mars is being hit by rapid climate change and it is happening so fast that the red planet could lose its southern ice cap, writes Jonathan Leake. Scientists from Nasa say that Mars has warmed by about 0.5C since the 1970s. [...]

National Geographic piece suggests that everything we know about mass extinctions may be wrong. Remarkable turn around this would be if it pans out. Everything you think you know is also wrong.

So, think this through with me. Firstly, let’s assume that evolutionary history consists of nearly infinite numbers of generations. “Gunfights,” in which inter-species and intra-species competition kills nearly everything alive, followed by massive repopulation, followed by more gunfights, average a lesser quantity of living gene replicas at any given moment in time, although any given [...]

Take a cryptographic key, encode as a 2D barcode, then load on to a camera phone by taking a picture of the key. Generalizes to other devices of course.
