Is this how life began? Here's a link to the full paper.

According to Rand Simberg's post on the topic, the article author Sylvain L. Smadja claims:
...Topics relevant to the Origin of Life that are addressed in this paper:
1. Why the relevant amino acids are all left-handed
2. Why there are 20 standard amino acids, and why those 20
3. Why the relevant amino acids are all "alpha-amino"
4. Why the relevant sugars are right-handed
5. The origin and preservation of homochirality
6. The origin of nucleobases A, G, C, U
7. The origin of RNA
8. The origin of the lipids
To put this into perspective, each one of these topics is a major big deal. That this model shows them as possibly being parts of interrelated cascading chemical steps is stunning. It is interesting to note that these chemical steps take place, not in a "primordial soup," but in a sheltered microenvironment of a mineral host structure. Since these proposed reactions do not work in water, the concept of life originating in a "primordial soup" may have mislead Origin of Life chemists for many decades.
Disclaimer: My own knowledge is molecular biology is inadequate to fully evaluate the author's theory.

Employment bleg: I'm posting this on behalf of my friend Brian who is looking for full or part-time work. (I'll keep this at the top of the site as a "sticky" for the next few days.)

He's a good guy and a hard worker. His background is as follows:
Engineering: PhD in electrical engineering (optics), optics laboratory experience, Matlab, LabView, Zemax, Comsol, finite-element analysis, numerical simulations

Writing/editing: Articles published in technical journals and major newspapers, copy-editing manuscripts, proofreading patents, seeing typos even when not looking for them

Public policy: Can quickly learn about public policy issues. Examples: health policy proposal made "Short List" of submissions to Colorado's Blue Ribbon Commission ('07), conference presentation on nanotechnology risks ('06), Nat'l Acad. Sciences Fellowship ('05)

Presenting/teaching: Presentations at technical conferences, performances in improv comedy shows, tutoring experience
Brian's resume is available here.

His e-mail address is: nanothought-z[at]yahoo.com

If you know anyone who might be interested in hiring someone with his skills, send him an e-mail!

Why there was a market for burnt-out light bulbs in the former USSR:
For most of us, it is hard to fathom the rationale for a market in burnt-out light bulbs. But in the scarcity-driven Soviet economy, the market was entirely reasonable. Light bulbs were rarely available to individual consumers, but were obtainable for state-sponsored activities.

Thus, it would be difficult to purchase a light bulb for a new lamp in one's home, while burnt-out bulbs in state-run offices or factories were routinely replaced. So if someone purchased a new lamp and needed a bulb, he would buy a used light bulb for a small fee and replace a functioning bulb at work with the dud. He would then take the functioning bulb home for the new lamp, while the burnt-out bulb at the office/factory would be replaced with a new functioning bulb.

Meanwhile, the maintenance person at the office/factory would take the used bulb and sell it on the used light bulb market...

"911 service not prepared for new generation of pranksters":
After paying a small fee to one of the readily available caller ID spoofing services available on the Web, a prank caller with a grudge or a serious psychological problem can call 911 and tell the operator just about any story he or she wants. Since the 911 system wasn't built with VoIP in mind, these calls appear to originate from anywhere, and said hooligans take full advantage of the opportunity. The practice has been dubbed "swatting," typically because the spoofed emergency stories that these troubled individuals make up are horrible enough to send police and even SWAT teams to unsuspecting victims on the other side of town or the continent.
Here is one example cited by the article.

The latest political status symbol is knowing the President's secret e-mail address:
...Those select few who have Mr. Obama's e-mail address, say people informed about the matter, include Rahm Emanuel, the White House chief of staff; David Axelrod and Valerie Jarrett, both senior advisers; and Robert Gibbs, the press secretary. But cabinet members like the interior secretary, Ken Salazar, said they did not have it. Secretary of State Hillary Rodham Clinton is a frequent BlackBerry user, but a spokesman said he did not know whether she had the president’s address.

iPhone app to solve Rubik's Cube:
CubeCheater is a new iPhone and iPod Touch app that solves everyone's favorite 80's puzzle cube. Just input the current state of your cube and CubeCheater will show you how to solve it.

Cubes can be entered by using the color palette and tapping in the colors, or you can just take a picture of each face of the cube and CubeCheater will use advanced computer-vision techniques to recognize the cube for you. (Camera feature not available on iPod Touch)

CubeCheater uses the famed Kociemba algorithm to find a solution quickly. It finds optimal or near-optimal cube solutions in only a few seconds. Even a really mixed-up cube will only take about 20 turns to solve, compared to hundreds of turns for a typical human algorithm.
