From Washington Post:

In the past, “nature” was used to maintain the status quo. A physician at Harvard University once cited biology as a reason to bar women from higher education: All that blood rushing to their brains would be drained from their wombs, he claimed, impairing their ability to bear children. Then the pendulum swung the other way. In the 1960s and ’70s, nearly every aspect of human behavior was attributed to “nurture,” including sex differences. If parents raised children the same way, giving dolls to boys and trucks to girls, they’d grow up acting the same.

In the 1990s, the pendulum swung again: A steady flow of books about evolutionary biology explained nearly every aspect of human behavior as a result of the organism’s urge to get its genes into the next generation — the female by ensuring her offspring’s survival, the male by spreading his sperm far and wide. And books such as Ann Moir and David Jessel’s Brain Sex , Deborah Blum’s Sex on the Brain and Melissa Hines’s Brain Gender provided accounts of gender differences based on brain structure and hormonal chemistry.

From MSNBC:

Dolphins may have big brains, but a South African-based scientist says lab rats and even goldfish can outwit them. Paul Manger of Johannesburg’s University of the Witwatersrand says the super-sized brains of dolphins, whales and porpoises are a function of being warm-blooded in a cold water environment and not a sign of intelligence. "We equate our big brain with intelligence.  Over the years we have looked at these kinds of things and said the dolphins must be intelligent," he said.

"The real flaw in this logic is that it suggests all brains are built the same … When you look at the structure of the dolphin brain you see it is not built for complex information processing," he told Reuters in an interview. A neuroethologist who looks at brain evolution, Manger’s views are sure to cause a stir among a public which has long associated dolphins with intelligence, emotion and other humanlike qualities. They are widely regarded as one of the smartest mammals.  But Manger, whose peer-reviewed research on the subject has been published in Biological Reviews of the Cambridge Philosophical Society, says the reality is different.

Brains, he says, are made of neurons and glia.  The latter create the environment for the neurons to work properly and producing heat is one of glia’s functions. "Dolphins have a super-abundance of glia and very few neurons … The dolphin’s brain is not made for information processing — it is designed to counter the thermal challenges of being a mammal in water," Manger said.

From Scientific American:

Television can act like a painkiller when it comes to children and is more effective than a mother’s comforting, according to a small Italian study. The University of Siena study, published in Archives of Disease in Childhood, was based on 69 children aged seven to 12 who were divided into three groups to have blood taken. One group was given no distraction while the blood was being taken while mothers of children in the second group attempted to distract the youngsters by talking to them, soothing, and/or caressing them. In the third group, the children were allowed to watch television cartoons while the procedure was being carried out.

The children recording the highest pain scores were in the group getting no distraction. More here.

Jonathan Curiel in Saudi Aramco World:

Sylviane Diouf knows her audience might be skeptical, so to demonstrate the connec- tion between Muslim traditions and American blues music, she’ll play two recordings: The athaan, the Muslim call to prayer that’s heard from minarets around the world, and “Levee Camp Holler,” an early type of blues song that first sprang up in the Mississippi Delta more than 100 years ago.

“Levee Camp Holler” is no ordinary song. It’s the product of ex-slaves who worked moving earth all day in post-Civil War America. The version that Diouf uses in presentations has lyrics that, like the call to prayer, speak about a glorious God. But it’s the song’s melody and note changes that closely resemble oneof Islam’s best-known refrains. Like the call to prayer, “Levee Camp Holler” emphasizes words that seem to quiver and shake in the reciter’s vocal chords. Dramatic changes in musical scales punctuate both “Levee Camp Holler” and the adhan. A nasal intonation is evident in both.

From The National Geographic:

They can crush a stack of concrete slabs with a bare fist, walk with catlike balance on a bamboo pole, and generate deadly kicks and punches at lightning-fast speeds. Real-life martial artists have long defied what many people would think is humanly possible, and their seemingly superpowered abilities have inspired generations of movies and television shows.

But where do the true skills end and the special effects begin? Maybe Hollywood magic doesn’t enter the equation as soon as you think. For the upcoming television special, Fight Science, researchers used high-tech equipment to put real martial artists to the test. The feature will air on August 20 on the National Geographic Channel. The action took place inside a specially designed film studio that is part laboratory and part dojo, a school for training in the various arts of self-defense. Here world champion martial artists from diverse disciplines were pitted against a customized crash-test dummy outfitted with impact sensors. The sensors—along with infrared, high-speed, and high-definition motion-capture cameras—allowed scientists to measure and map the speed, force, range, and impact of the fighter’s techniques.

The result is an unprecedented look at how martial artists generate the power and speed behind each move.

Azra posted this a couple of days ago at 3QD. Carl Zimmer has more thoughts about it in his blog, The Loom:

Can a tumor become a new form of life?

This is the freaky but serious question that arises from a new study in the journal Cell. Scientists from London and Chicago have studied a peculiar cancer that afflicts dogs, known as canine transmissible venereal tumor (CTVT) or Sticker’s sarcoma. It is a cancer of immune cells called histiocytes, and dogs typically develop grapefruit-sized tumors that disappear after a few months…

So here’s the big question which the authors don’t tackle head on: what is this thing? Is it a medieval Chinese dog that has found immortality? If so, then it resembles HeLa cells, a line of cancer cells isolated from a woman named Henrietta Lacks who died in 1951. After her death, scientists have propagated her cells, and in that time they have have adapted to their new ecological niche of Petri dishes, acquiring mutations that make it grow aggressively in the lab. One biologist even suggested that the cells should be consider a new species.

Sticker’s sarcoma has, without any intervention from scientists, become a cell line as well, and one that has survived far longer than HeLa cells have. It is distinct from its dog ancestors, and has acquired adaptations that allow it to manipulate its hosts for its own advantage as effectively as a virus or a blood fluke. A parasite evolved from a dog, perhaps.

RECENTLY, THE BIG-SCREEN VERSION of “Miami Vice” and the 25th birthday of MTV reminded us of how the small-screen fare of the 1980s ushered in a flashy, high-velocity aesthetic that transformed the moving image as we knew it. The timing seems especially apt because, at least for this viewer, 2006 marks the moment that the dizzying pinball effect of hyperspeed editing has finally permeated every last corner of mainstream American cinema-not just the ADD-inducing action spectaculars that breed in summertime, but also the character-driven, explosion-free films offered as an alternative to the blockbusters.

Even though moviegoers who never before gave a thought to film grammar can now put together epics on their laptops using iMovie and Final Cut Pro, film editing remains perhaps the least heralded and least understood of the cinema’s technical arts. The editor Walter Murch, whose astonishing resume includes the “Godfather” films, “Apocalypse Now,” and “The English Patient,” has said that film editing “could just as easily be called `film construction.”‘

3 Years 3 Minutes is a short film composed entirely of 11896 photos taken by Felix Jung over 3 years.

From the project’s about page:

I originally got the idea after importing my photos into Picasa, and watching thumbnails of each image flash by. Seeing that mini-movie, I decided a larger, sped-up version would be pretty neat to view.

…

At the end of the day, I intended for this project to be a sort of summary - an accounting for how I spent my time. While there’s a lot that happens within a year, a year goes by faster than we realize.

I wanted to portray both sensations, the density and rapidity of it all. I hope this little movie came close to capturing that feeling.

ur of images is often overwhelming and exhilarating. The music supplies a sense of rhythm and structure to that blur.

There are serendipitous moments where two or three subframes show images related to each other in terms of people and events depicted or visual aspects like color and dominant shapes. I would have preferred to see more moments like that, making use of the split screens to create and show linkages across three years, but it would be a different project and a different film.
