Genes and Jews.
And you thought Spock
came up with that part of the shtick. It turns out that despite the racial and ethnic diversity of the Tribe, there are genetic markers that identify Cohanim, or the priestly descendants of Aaron (know any Cohens?). These markers help identify jewish identity in the most distant reaches of the diaspora.
The fascinating intersection of anthropology, genetics, and religion.

How do we see?
This site by Dr. Dale Purves makes it obvious we don't see things like a camera in any way. Check out the interactive demos, test your perceptual abilities, and read the research explaining why this happens. Number 12: Color Contrast Cube is particularly startling. Warning: Totally Flash interface, but appropriate for subject matter. More experiments at a less Flash-y associate's site

What Comes Next?
Big scientists answer some big questions: apparently Elvis may still be alive in a parallel universe.

Draw a straight line on top of the car, lift the pen and the car shoots off in a straight line. Draw a circle on the car and the car starts wildly spinning around. Draw a complicated squiggle and the car spirals in and out. Quicktime Video Link#1

Mystery of 'chirping' pyramid decoded:
"A theory that the ancient Mayans built their pyramids to act as giant resonators to produce strange and evocative echoes has been supported by a team of Belgian scientists." Others are not so sure... Coincidence, or engineering? Did the designers of El Castillo pyramid
cannily build in a sound effect that mimics the warble of the sacred quetzal bird? Listen for yourself, with the .wav file
(first set is the real bird, the second is the pyramid) featured in this Acoustical Society of America page
. I prefer to think it's deliberate; after all, it's possible that early man was experimenting with cave acoustics to to create sound-enhanced rock art
(there are sound samples for this included here
- unfortunately a Geocities site). Also of interest, the BBC programme "Acoustic Shadows
" (requires RealPlayer - *heavy sigh*)

Hypothesis as thought-crime
...Now, however, a new brouhaha has erupted [at Harvard]and it seems impossible that Summers [the president]will emerge from this one without serious erosion of his moral authority. The trigger was a statement he made at a conference, suggesting that the reason there are more men than women in the mathematical sciences at top-flight institutions has to do with a small statistical difference in inate ability, which becomes a pretty large disparity when one looks at the 'high end' of the respective distribution curves...
The fatal words did not set forth his main theme, but merely constituted a brief aside, thoroughly hedged and qualified. Nonetheless, they touched off a firestorm of indignation, the most striking aspect of which was the intemperate response of a number of feminist scientists, who offered no counter-arguments, but simply declared the whole idea misogynistic and therefore forbidden intellectual territory.

Come out, experts from the woodworks!
Neu5Ac and Neu5Gc are sugars found on cells present in nearly every mammal, from chimps to pigs. When scientists altered the genes of mice so that they couldn't produce them, the mice died. However, unlike our closest relatives, humans lack a gene that makes Neu5Gc. The gene is not gone, but rendered silent by a fatal mutation, one that occured approximately 500,000 ago. Now, note that it is illegal to produce any new embryonic stem cell lines. Any scientist will tell you that extant and legal human stem cell lines have been existing in calf serum and often on layers of mouse "feeder" cells for growth. As such, they are immersed in a bath of antigen and if re-introdcued would elicit a strong immune response. I.e. although of human origin, they would be treated as foreign cells if injected. It is likely they would be rejected if injected with today's techniques anyway, but this may represent another significant hurdle for research, one that could be sidestepped with more progressive policy.

It's Carnival Time! In 2002, Silflay Hraka
launched the internet's first carnival: The Carnival of the Vanities
. Carnivals are showcases of the best that blogs have to offer; bloggers send in posts they have made that they are especially pleased with, and a rotating editor collates them into a weekly edition with editorial comments. Think of carnivals as best-of-the-blogosphere magazines. The Carnival of the Vanities (current edition here
) doesn't have any particular focus, but a number of offshoots dedicated to specific fields have popped up. Stay up to date on blog postings about philosophy
, the early modern period
, and (if desperately bored) cats
. A new carnival about atheism, The Carnival of the Godless
, will be coming out at the end of the month.

Instead of liquid water, Titan
has liquid methane. Instead of silicate rocks, Titan has frozen water ice. Instead of dirt, Titan has hydrocarbon particles settling out of the atmosphere, and instead of lava, Titanian volcanoes spew very cold ice.

Life in the future.
In the year 2,000 "everything will be so easy that people will probably die from sheer boredom." Workweeks will be 24 hours and the home computer will be the new status symbol.

The scientific method is a tool for determining objective truth about the world around us, right? But not everybody thinks so. From being a proof of God's existance to a mere socio-pilotical construct, scientific humanism is under attack.
