A small ocean microbe called Pelagibacter has the smallest genome of any self-sufficient organism with 1,354 genes. It also doesn’t appear to have any extra DNA…no junk or redundant copies of genes.

Interview with Frans de Waal about his
Interview with Frans de Waal about his work with primate behavior and politics. “I call the human species the most bipolar ape, meaning that we go beyond chimps in our violence, which is systematic and often results in thousands of dead, and we go beyond the bonobo in our empathy and love for others, so that human altruism is truly remarkable.”
Pharyngula rips Deepak Chopra a new one
Pharyngula rips Deepak Chopra a new one regarding his skepticism of evolution. Skepticism is fantastic, but Chopra seems to be deeply engaged in an impressive display of uninformed hand-waving. Deep, put down your cup of invigorating tea and at least read a little about what evolution is so that next time, you actually sound like you know what you’re being skeptical about.
Evolution shocker!
Evolution shocker! The discovery of a dinosaur footprint on the wall of a contemporary Brooklyn school proves that the earth is less than 6000 years old (and, perhaps, that dinosaurs could walk vertically). No word on the Flying Spaghetti Monster’s involvement.
Biologists are beginning to simulate living things
Biologists are beginning to simulate living things by computer, molecule by molecule. They’re starting with E. coli, but they’ve still got a long way to go.

Spirals on nanoparticles show order, specifically our friend the Fibonacci sequence, which can be seen in places like seashells and plants. In the case of the nanoparticles, the Fibonacci pattern results from minimizing the stress energy in the system.

Can we out-collaborate a pandemic? Alex Steffen challenges the blogosphere to sound the alarm about the avian flu. The WHO says: “never before [has] any avian influenza virus caused such extremely high fatality in humans”.
When bent, why does dry spaghetti break
When bent, why does dry spaghetti break into three or more pieces instead of two? This was one of the simple problems Richard Feynman amused himself with but never solved. Someone’s come up with the answer: when the first breakage occurs, it causes a local increase in the curvature of the two pieces, resulting in more breakage. (thx dj)

Modelling nuclear decay in atoms may tell us something about dating and relationships. One of the findings: people who date often are beneficial to the dating ecosystem “because they break up weak couples, forcing their victims to find better relationships”.
Science and drugs
Scientists who have tried drugs have included Carl Sagan, Richard Feynman, and Stephen Jay Gould. Like Sigmund Freud, fictional detective Sherlock Holmes was a fan of cocaine. (via cyc-c)

Ishmael
When I posted a link to Jared Diamond’s Discover magazine piece on agriculture being “the worst mistake in the history of the world”, two people wrote in suggesting that I read Daniel Quinn’s Ishmael. As I was between books, I did just that. Ishmael, nutshelled:
Ishmael’s paradigm of history is startlingly different from the one wired into our cultural consciousness. For Ishmael, our agricultural revolution was not a technological event but a moral one, a rebellion against an ethical structure inherent in the community of life since its foundation four billion years ago. Having escaped the restraints of this ethical structure, humankind made itself a global tyrant, wielding deadly force over all other species while lacking the wisdom to make its tyranny a beneficial one or even a sustainable one.
That tyranny is now hurtling us toward a planetary disaster of pollution and overpopulation. If we want to avoid that catastrophe, we need to work our way back to some fundamental truths: that we weren’t born a menace to the world and that no irresistible fate compels us to go on being a menace to the world.
It’s a work of philosophy, centering on technology, culture, religion, and ecology. The Platonic-dialogue-with-a-gorilla format seemed forced to me (Quinn wrote the novelized version of this story to win a $500,000 book prize)…I guess I would have preferred the shorter essay version. But Quinn’s main thesis is an interesting one and worth considering.

Butterfly team colors may discourage inter-species mating
Butterfly team colors may discourage inter-species mating and pave the way for the development of separate species. “This process, called ‘reinforcement’, prevents closely related species from interbreeding thus driving them further apart genetically and promoting speciation.”
Robot Lucy
Robotics research suggests that Lucy walked upright like humans. Lucy, discovered in 1974 in Ethiopia, is a 3.2 million year old Australopithecus afarensis skeleton.

The importance of narrative in science. “Science and stories are not only compatible, they’re inseparable, as shown by Einstein’s classic 1905 paper on the photoelectric effect”.
