1. ENERGY LEGISLATION: JIMMY CARTER'S "MORAL EQUIVALENT OF WAR."

After years of trying to drill our way out of the energy crisis, we have another chance to do what we should have done all along: increase efficiency. It would put us a lot closer to meeting carbon emission goals. Both houses of Congress passed energy bills; they must now be reconciled by a conference committee. Historically, this is where it falls apart - the conferees tend to keep sugar and fat in both bills and slash the broccoli. We need the 35 mpg fuel economy in the Senate bill, and the 15% renewable electricity requirement in the House bill, as well as cuts of some oil-industry tax breaks. Finally, both bills call for more ethanol from corn. That's just crazy! For all its good intentions, ethanol from corn doesn't balance. Why can't scientists make themselves heard on a simple question of energy?

2. DIPLOID GENOME: CRAIG VENTER STANDS BEFORE US STARK NAKED.

An academic consortium announced in 2003 that the human genome had been successfully decoded, but the other runner in the race, J. Craig Venter of the J. Craig Venter Institute just kept running. He says the consortium stopped half way to the goal. The consortium, led by James Watson, co- discoverer of the double helix, had decoded the male haploid genome, from a group of people from different racial and ethnic backgrounds. Venter has decoded the full diploid genome of just one person - himself. So far, the experts seem to agree that Craig's genome is better, which is not to say he has better genes. He has genes linked to Alzheimer's, alcoholism, obesity, antisocial behavior, tobacco addiction, substance abuse, and wet earwax. And if there's a gene for vanity, he's probably got that too. Having those genes does not mean he has those conditions. It does explain why privacy advocates would be concerned about decoding the genome.

3. BRAIN IMAGING: WHY DO PEOPLE BEHAVE LIKE, WELL, PEOPLE?

Dopamine, a powerful neurotransmitter, plays a key role in addiction. Imaging shows that people addicted to alcohol or to methamphetamine have fewer dopamine receptors than healthy people, and so, it turns out, do obese people, suggesting eating may be addictive. Human behavior used to be considered a "soft science." Brain imaging and genome studies have made it a frontier.

4. MOONSHINE: WE MISSPOKE LAST WEEK ABOUT CHANDRAYAAN-1.

The Indian spacecraft will not commit suicide. It will stay in orbit and drop a probe to the surface, sacrificing its offspring for enlightenment. It sounds right out of the Old Testament.
