“Homophobia is apparently associated with homosexual arousal that the homophobic individual is either unaware of or denies.”

Grats for these folks for scientifically confirming this one.

Possibly habitable exoplanet found

“Gliese 581d — can be considered the first confirmed exoplanet that could support Earth-like life”

“the most important implication of these results may be the idea that life-supporting planets do not in fact need to be particularly like Earth at all.”

Kyberwar, going on, right now

“Iran’s president has said some of the centrifuges used in its uranium enrichment programme were sabotaged, raising suspicions that they were targeted by the Stuxnet computer worm.”

via BBC News – Iran says nuclear programme was hit by sabotage.

So, the most complicated worm in history, Stuxnet, was confirmed to have worked exactly as intended. It apparently made Iranian centrifuges used to enrich uranium speed over their safe limits thus breaking them.

And now we also know that the Iranian scientist assassinated yesterday was the most knowledgeable guy about fighting Stuxnet in Iran.

What a.. coincidence.

All in all, this plot is straight from cyberpunk novel. And unfolding right here, right now.

With the level of dedication and professionalism involved here Mossad becomes my main bet for the guys pulling the strings.

Kivikauden ihmiset söivät hiilihydraatteja – HS.fi – Ulkomaat

kivikauden ihmiset keräsivät ja kuivasivat kasveja ja jauhoivat niitä ravinnoksi jo 30 000 vuotta sitten. Löytö muuttaa käsityksiä, joiden mukaan kivikauden ihmisten ruokavalio olisi koostunut vain lihasta ja satunnaisista marjoista ja hedelmistä.

A Better Way to Reprogram Cells – ScienceNOW

These folks have found a way to make stem cells and then program then to specialize to certain type of tissue, like muscle tissue, that uses cells from adult and synthetic RNA. The main difference to earlier methods is that the resulting tissue does not carry any leftover DNA from the reprogramming process.

Eyjafjallajökull and Katla: restless neighbours « The Volcanism Blog

There’s been a lot of mentions in the news about Katla always erupting when Eyjafjallajökull does, but no time frames have been mentioned. It was a bit challenging to dig it up, but here it is:

Eyjafjallajökull’s most recent eruption, December 1821 to January 1823, was followed by an eruption of Katla in June and July 1823

Eyjafjallajökull and Katla: restless neighbours « The Volcanism Blog.

The one before that was in 1600s and it’s a bit uncertain if both even erupted then, let alone knowing which one went first.

With these 1.5 data points it seems we might very well have some time to fly around right now.

The eruption of Katla is well past the schedule, however, so if not right now (meaning in year or two), it will happen soonish, unless something extraordinary happens. There’s record of Katla erupting from 900s to present and it has been erupting twice per century all these centuries, and now it’s already 92 years from the previous one (1918).

Why Do Chinese Save? Boys Want to Marry

I have long suspected the skewed sex ratio in some large asian countries will cause unpredicted sociological and economical consequences. This is one of them:

Across Chinese provinces, there is clear evidence that local savings rates tend to be higher in regions with more unbalanced sex ratios.
