Yesterday, one of the stars went out.

Sir Arthur C. Clarke wasn't just a "futurist" who wrote about possibilities. He was an integral part of the community which made our global society possible. His first novel, Glide Path, was based on his WWII experiences using radar for the first time as a means to help aircraft land. And most appropriately, he was the first person to realize the potential power of planting a satellite at 35,780km and using it for communications.

But Clarke's fiction wasn't about science and technology. Like the best science fiction authors, he merely used those to talk about what it meant to human. His focus was on communities, on the importance of understanding our own planet, and on reaching our greatest potential as human beings without forgetting that we have a responsibility to all life on this planet.

The best obituary you can offer him is to go and read one of his books. Or better yet, give one to a child to read.

I find it fascinating (and appropriate) to watch the remembrances as they wend their way through the time zones. Here is a sampling (via Tweet Scan).

While I'm sure having scientific evidence for the G spot will reassure all those women who previously thought they were imagining their orgasms, what I really found interesting was this.

The elusive G spot really does exist, say researchers The Guardian

The research supports a previous study by the team which reported differences in the chemical make-up of the G spot tissues. Women who appear to have a G spot produced specific chemicals, including an enzyme that processes nitric oxide, the substance that triggers male erections.

That's a wonderful piece of biological feedback. Stimulating the G spot produces chemicals that trigger and (I presume) help maintain male erections. You gotta love nature.

The other interesting tidbit from the article (which goes a long way in explaining why it was a controversy in the first place) is that not only is this an easily recognizable area in the vagina, but some women have it, and some don't. So a quick examination can determine whether or not you are capable of having G spot orgasms.

(The article is safe for work, unless you count the gratuitous picture of Meg Ryan pretending to have an orgasm. I bet she just loves that picture.)

That's what Pooh said when Rabbit asked him if he wanted honey or butter with his bread. The right answer for eating perhaps (or not, if you recall what happened to Pooh next), but it turns out that for burns, one should stick to just the honey.


Honey Can Soothe a Burn New York Times

In studies of quick and easy treatments to soothe mild burns, scientists have found that honey has antibacterial and anti-inflammatory properties that may promote healing. One study in 2006, examining results of more than a dozen previous studies, found that small, nonserious burns healed faster when treated with gauze and a dash of honey, on average, than those treated with antibiotic creams and other dressings. A separate report published earlier found similar results.

Butter, on the other hand, can lead to infections.

A great step in the search for extraterrestrial life, but also cool in that it shows that the amateur astronomer is still a major player in discoveries.

Scientists Find Solar System Like Ours New York Times

The new discovery was made by a different technique that favors planets more distant from their star. It is based on a trick of Einsteinian gravity called microlensing. If, in the ceaseless shifting of the stars, two stars should become perfectly aligned with the Earth, the gravity of the nearer star can bend and magnify the light from the more distant one, causing it to suddenly get much brighter for a few days.

If the alignment is especially perfect, any big planets attending the nearer star will get into the act, adding their own little bumps to the more distant starlight.

That is exactly what started happening on March 28, 2006, when a star 5,000 light years away in the constellation Scorpius began to pass in front of one 21,000 light years more distant, causing it to flash. It was picked up by the Optical Gravitational Lensing Experiment, or Ogle, a worldwide collaboration of observers who keep watch for such events.

Ogle in turn immediately issued a worldwide call for continuous observations of what is now officially known as OGLE-2006-BLG-109L. The next 10 days, as Andrew Gould of Ohio State said, were “extremely frenetic.”

Among those who provided crucial data and appeared as lead authors of the paper in Science were a pair of amateur astronomers from Auckland, New Zealand, Jennie McCormick and Grant Christie, both members of a group called the Microlensing Follow-Up Network, or MicroFUN. Ms. McCormick, who described herself as “an ordinary New Zealand mother,” said she had done her observing with a 10-inch Meade telescope from a shed in her back yard.

Here's the Microlensing Follow-Up Network (MicroFUN) web site.

And nothing about space would be complete without an artist's conception. :-)

Memory - Aging New York Times

But when these sharp old folks die, autopsy studies often reveal extensive brain abnormalities like those in patients with Alzheimer’s. Dr. Nikolaos Scarmeas and Yaakov Stern at Columbia University Medical Center recall that in 1988, a study of “cognitively normal elderly women” showed that they had “advanced Alzheimer’s disease pathology in their brains at death.” Later studies indicated that up to two-thirds of people with autopsy findings of Alzheimer’s disease were cognitively intact when they died.

Interesting. In summary, this study shows that Alzheimer's isn't in itself a reason for decreased mental functions. Some people who remained mentally active by doing lots of things requiring mental skills, had normal cognitive skills even though autopsies showed that they had Alzheimer's.

Of course, just to put a mild damper on it, I'll point out that we don't *know* that the mental activity actually prevented harm. For all we know there's some other genetic difference which makes it possible for some people to work around the damage. But in the meantime. Keep mental exercising! (Mentaling?).
