Stanislaw Lem’s Summa Techologiae

Monday, February 4th, 2013

Orthofer over at the Literary Saloon points out that Stanislaw Lem’s Summa Techologiae is being published in English for the first time. Hell, yes. I probably was dimly been aware of this, but it’s hard to keep track of this stuff when one is an easily distracted flake. The new excitement overwhelms any memory of anticipation.

This winter I tried filling in a few more missing pieces of Lem’s work in my library. One of the books was A Stanislaw Lem Reader. (Thank you, Peter Swirski and Northwestern University Press.) It was amazing work, but as Orthofer points out, some of Lem’s ideas now come across as a bit dated. But also like him, I’m still in awe of Lem. That was one hell of a mind.

(Also, I’m embarrassed to admit that Philip K. Dick’s Exegenesis has been on my shelf for over a year, and I stalled out pretty early, despite some conscientious returns to pick through it. )

quantum biology

Monday, February 4th, 2013

Anyone feel daring enough to make a fool of himself, to venture a guess that anything we recognize as psychic phenomenon (by that, I mean the things which aren’t total bullshit to begin with) and the soul might come out of the research in quantum biology? The New Age quacks will be all over this, building elaborate systems out of these fragments of information that will rival any role playing game. However, simple universal mechanism isn’t going to work for explaining every biological system much longer.

And honestly, I look forward to the weird mess that results.

Dawkins versus Wilson

Monday, June 25th, 2012

The article is mostly a summary, but then a third party weights in. Go, Georgy Koentges, go!

“There is no such thing as a good or bad gene. It doesn’t work that simply. Genes are used and re-used in different contexts, each of which might have a different overall fitness value for a given organism or a group.”

One thing that bugged me in the article was the writer using “Darwinist.”  “Darwinist” is a pejorative and a shibboleth. Dawkins is not a Darwinist. Creationists tend to use that term, in the naive assertion that Charles Darwin is some cult leader or prophet to a belief in evolution, rather than a scientist who advanced human knowledge.

Besides, Dawkins is a Dawkinsist, if anything.

age of western branch of East African Rift Valley redated

It’s now dated at the same age as the eastern branch, 25 to 30 million years ago.

Footage Of A White Blood Cell Hunting Down A Cancer Cell

Thursday, March 15th, 2012

University of Cambridge researchers have captured stunning microscopic footage of how killer T cells (a type of white blood cell) can protect the body from pathogens. The video shows a T cell hunting down a cancer cell and engulfing it.

Cytotoxic T cells are just 10 microns in length, approximately one-tenth the width of a human hair. The actual action has been sped up and appears 92 times faster in the video.

The microscopic footage was shot by PhD student Alex Ritter, in the laboratory of Gillian Griffiths, a professor of immunology and cell biology at Cambridge.

How will this help cancer research? On the YouTube page, professor Griffiths explains it this way:

“Cytotoxic T cells are very precise and efficient killers. They are able to destroy infected or cancerous cells, without destroying healthy cells surrounding them . . . By understanding how this works, we can develop ways to control killer cells. This will allow us to find ways to improve cancer therapies, and ameliorate autoimmune diseases caused when killer cells run amok and attack healthy cells in our bodies.”

elements of Neandertal language still extant?

Sunday, March 11th, 2012

What the hell is this about a point of origin of language in the Caucasus mountains in addition to East Africa? And Dienekes comments about Kibari Neandertals having hyoid bones well-developed enough for possible speech?

Nifty observation. More, please.

The comment and the original paper.

foot bone found at Denisova site

Friday, August 19th, 2011

What might be a Denisovan foot bone has been excavated from the same layer of the cave that the Denisovan finger bone was found. Both are roughly 40,000 years old, but the problem with declaring it definitely a Denisovan bone already is that Neanderthals were in that area at the same time and only two Denisovan bones have been identified to date. The New Scientist article notes that the team’s enthusiasm hints that again they have been able to extract DNA from the bone and it’s not Homo sapiens or Neanderthal.

archaic humans contributed useful traits to Homo sapiens genome through interbreeding

Wednesday, August 17th, 2011

Ha ha! Not only did Homo sapiens interbreed with archaic humans, but it acquired useful traits from them. I eagerly await more finds of other archaic humans that contributed to the human genome. It seems likely that Neanderthals and Denisovans weren’t the only ones around.

Good old John Hawks makes the comment, “These genomes are publicly available. There’s nothing stopping high-school students from doing this, and the kind of stuff that I’m putting out on my blog is the stuff that a smart high-school student could do.” I love that guy. His blog is a long time favorite. His visit to the Denisova site this summer was a recent highlight.

putting the area of the Deepwater Horizon oil spill into perspective

Monday, May 10th, 2010

A gentleman has fooled around with Google Earth allow a user to overlay the current size of the Deepwater Horizon oil spill over several preset areas, like Manhattan, San Francisco, and several other places. One can input other locations well. (For any of it to work, the Google Earth plug-in must be installed.)

I knew that the spill was massive and devastating, but seeing these overlays makes just a little bit more grim. And that area is from around May 2nd. Check it out now.
