Evidence “of Complex Human Cognition” 100,000 Years Ago

“Deposits of 100,000-year-old ocher were found in a shell alongside tools for pounding and grinding paint materials.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. A12) Digging deeper in a South African cave that had already yielded surprises from the Middle Stone Age, archaeologists have uncovered a 100,000-year-old workshop holding the tools and ingredients with which early modern humans apparently mixed some of the first known paint.

These cave artisans had stones for pounding and grinding colorful dirt enriched with a kind of iron oxide to a powder, known as ocher. This was blended with the binding fat of mammal-bone marrow and a dash of charcoal. Traces of ocher were left on the tools, and samples of the reddish compound were collected in large abalone shells, where the paint was liquefied, stirred and scooped out with a bone spatula.
Archaeologists said that in the workshop remains they were seeing the earliest example yet of how emergent Homo sapiens processed ocher, one of the species’ first pigments in wide use, its red color apparently rich in symbolic significance. The early humans may have applied the concoction to their skin for protection or simply decoration, experts suggested. Perhaps it was their way of making social and artistic statements on their bodies or their artifacts.
Of special importance to the scientists who made the discovery, the ocher workshop showed that early humans, whose anatomy was modern, had also begun thinking like us. In a report published online on Thursday in the journal Science, the researchers called this evidence of early conceptual abilities “a benchmark in the evolution of complex human cognition.”
The discovery dials back the date when the modern Homo sapiens population was known to have started using paint. Previously, no workshop older than 60,000 years had come to light, and the earliest cave and rock art began appearing about 40,000 years ago. The exuberant flowering among the Cro-Magnon artists in the caves of Europe would come even later; the parade of animals on the walls of Lascaux in France, for example, was executed 17,000 years ago.
. . .
Alison S. Brooks, an archaeologist at George Washington University who studies the Middle Stone Age in Africa but was not involved in this research, said, “This is another spectacular discovery from Blombos.”

How Entrepreneurship Rebuilt San Francisco After the Fire

(p. 5) At 5:12 a.m. on April 18, 1906, Amadeo Peter Giannini felt an odd sensation, then a violent one, a slight, almost imperceptible shift in his surroundings coupled with a distant rumble like faraway thunder or a train! Pause. One second. Two seconds. Then-bang!-his house in San Mateo, California, began to pitch and shake, to, fro, up, and down. Seventeen miles north in (p. 6) San Francisco, the ground liquefied underneath hundreds of buildings, while heaving spasms under more solid ground catapulted stones and facades into the streets. Walls collapsed. Gas mains exploded. Fires erupted.

Determined to find out what had happened to his fledgling company, the Bank of Italy, Giannini endured a six-hour odyssey, navigating his way into the city by train and then by foot while people streamed in the opposite direction, fleeing the conflagration. Fires swept toward his offices, and Giannini had to rescue all the imperiled cash sitting in the bank. But criminals roamed through the rubble, prompting the mayor to issue a terse proclamation: “Officers have been authorized by me to KILL any and all persons found engaged in Looting or in the Commission of Any Other Crime.” With the help of two employees, Giannini hid the cash under crates of oranges on two commandeered produce wagons and made a nighttime journey back to San Mateo, where he hid the money in his fireplace. Giannini returned to San Francisco the next morning and found himself at odds with other bankers who wanted to impose up to a six-month moratorium on lending. His response: putting a plank across two barrels right in the middle of a busy pier and opening for business the very next day. “We are going to rebuild San Francisco,” he proclaimed.

Giannini lent to the little guy when the little guy needed it most. In return, the little guy made deposits at Giannini’s bank. As San Francisco moved from chaos to order, from order to growth, from growth to prosperity, Giannini lent more to the little guy, and the little guy banked even more with Giannini. The bank gained momentum, little guy by little guy, loan by loan, deposit by deposit, branch by branch, across California, (p. 7) renaming itself Bank of America along the way. In October 1945, it became the largest commercial bank in the world, overtaking the venerable Chase National Bank. (Note of clarification: in 1998, NationsBank acquired Bank of America and took the name; the Bank of America described here is a different company than NationsBank.)

Entrepreneur Julius Blank’s Greatest Pleasure Came from “Building Something from Nothing”

“Fairchild Semiconductor’s founders in 1988. Victor Grinich (left), Jay Last, Jean Hoerni, Julius Blank, Eugene Kleiner, Sheldon Roberts, Robert N. Noyce (seated, left,) and Gordon E. Moore.” Source of caption and photo: online version of the NYT obituary quoted and cited below.

(p. B14) Julius Blank, a mechanical engineer who helped start a computer chip company in the 1950s that became a prototype for high-tech start-ups and a training ground for a generation of Silicon Valley entrepreneurs, died on Saturday in Palo Alto, Calif.. He was 86.
. . .
Mr. Blank and his partners — who included Robert N. Noyce and Gordon E. Moore, the future founders of the Intel Corporation — began their venture as scientist-entrepreneurs in the wake of a mutiny of sorts against their common previous employer, the Nobel Prize-winning physicist William B. Shockley.
Dr. Shockley, . . . , had recruited the eight scientists from around the country in 1956 to work in his own semiconductor lab in nearby Mountain View, Calif.
The group left en masse the next year because of what its members described as Dr. Shockley’s authoritarian management style and their differences with him over his scientific approach. Dr. Shockley called it a betrayal.
Fairchild’s founders came to be branded in the lore of Silicon Valley as the “Traitorous Eight.” How that happened remains something of a mystery.
. . .
When he left Fairchild in 1969 — he was the last of the eight founding partners to depart — Mr. Blank became an investor and consultant to start-up companies and helped found the technology firm Xicor, which was sold in 2004 for $529 million to Intersil.
His former partners, in addition to founding Intel, had started Advanced Micro Devices and National Semiconductor. Mr. Kleiner had founded a venture capital firm that became an early investor in hundreds of technology companies, including Amazon.com, Google and AOL. Still, the greatest pleasure of his working life, Mr. Blank said in a 2008 interview for the archives of the Computer History Museum, a project in Silicon Valley, came with the uncertainty and camaraderie of “the early years, building something from nothing.”
Mr. Blank described a moment in the first days of Fairchild, just before production began in its factory built from nothing, when the ducts and plumbing and air-conditioning were set, and the new crystal growers and one-of-a-kind chip making machines were ready to be installed.
“I remember the day we finally got the floor tile laid,” he said. “And that night, Noyce and the rest of the guys came out and got barefoot and rolled their pants up and were swabbing the floors. I wish I had a picture of that.”

Steve Jobs on Public School System Monopoly

(p. A15) These days everyone is for education reform. The question is which approach is best. I favor the Steve Jobs model.
In 1984 Steve introduced the Mac with a Super Bowl ad. It ran only once. It ran for only one minute. And it shows a female athlete being chased by the helmeted police of some totalitarian regime.
At the climax, the woman rushes up to a large screen where Big Brother is giving a speech. Just as he announces, “We shall prevail,” she hurls her hammer through the screen.
If you ask me what we need to do in education, I would point you to that ad.
. . .
Steve Jobs knew all about competitive markets. He once likened our school system to the old phone monopoly. “I remember,” he said in a 1995 interview, “seeing a bumper sticker with the Bell Logo on it and it said ‘We don’t care. We don’t have to.’ And that’s what a monopoly is. That’s what IBM was in their day. And that’s certainly what the public school system is. They don’t have to care.”
We have to care. In this new century, good is not good enough. Put simply, we must approach education the way Steve Jobs approached every industry he touched. To be willing to blow up what doesn’t work or gets in the way. And to make our bet that if we can engage a child’s imagination, there’s no limit to what he or she can learn.

Creativity Continues at Disney

“‘We’re kind of like an old married couple,’ said Imagineer Chris Crump, center, of his longtime colleague Larry Nikolai, right. Lisa Girolami, the ride’s producer, is left. It took nearly four years to conceive and build ‘Ariel’s Undersea Adventure,’ which opened at Disney California Adventure Park last week. The trio spearheaded a group of over 100 designers, architects, lighting experts and other specialists.” Source of caption and photo: online version of the WSJ article quoted and cited below.

(p. C11) It took nearly four years to conceive and build a theme-park ride that put visitors inside the world of “The Little Mermaid,” including several musical numbers, a few key narrative moments and 184 figures from Disney’s animated hit.

And that followed the 18 years it took to settle on an approach to the ride, which was on the entertainment giant’s to-do list almost from the day the film was released in 1989. The ride finally opened last week at Disney California Adventure, Disneyland’s younger neighbor, and takes visitors through a condensed version of the movie’s narrative, cramming nine scenes and four songs into 5½ minutes.
. . .
They start by thinking big: Ms. Girolami described their brainstorming sessions as “an iterative process”–first deciding what parts of the movie to retell, then returning to the drawing table as the decision-making focuses to smaller and smaller details.
Then, helped by “rapid prototyping,” a technology that allows them to generate physical models directly from computer-design files, the group tests and retests their models.
. . .
The Imagineers pride themselves on their never-say-die spirit. “We commit to things creatively that haven’t been done,” Ms. Girolami said. “Someone will say, ‘That’s never been done before,’ and it’s our job to say, ‘Great–let’s do it.’ “

Jobs, Hope and Cash

(p. A15) ‘Ten years ago, Steve Jobs was alive, Bob Hope was alive, Johnny Cash was alive. Now we’re outta jobs, outta hope and outta cash.” I heard that from a TSA agent in New York the other day, as he eyed me for explosives. We laughed, but there was a poignant edge.
Part of the outpouring over Steve Jobs last week was that he was a huge symbol of what seems a lost world of American dynamism. The inventor in his garage changes the world. We’ll not only make the new machine powerful and fast, we’ll make it so beautiful it will make you cry. Like you’re looking at the future, like you’re looking at a baby in its crib.

Jim Collins’ business books are usually sensible, and are full of arresting examples and memorable hypotheses. His latest full-scale research effort (Great by Choice) is just out, but I have not yet read it. In the next few weeks, I will quote a few of the more thought-provoking or useful passages in his 2009 small book How the Mighty Fall.

Science Not Accurate at Predicting Storm Intensity

(p. D1) For scientists who specialize in hurricanes, Irene, which roared up the Eastern Seaboard over the weekend, has shone an uncomfortable light on their profession. They acknowledge that while they have become adept at gauging the track a hurricane will take, their predictions of a storm’s intensity leave much to be desired.

Officials with NOAA’s National Hurricane Center had accurately forecast that Irene would hit North Carolina, and then churn up the mid-Atlantic coast into New York. But they thought the storm would be more powerful, its winds increasing in intensity after it passed through the Bahamas on Thursday.
Instead, the storm lost strength. By the time it made landfall in North Carolina two days later, its winds were about 10 percent lighter than predicted.
It’s not a new problem. “With intensity, we just haven’t moved off square zero,” Dr. Marks said. Forecasting a storm’s strength requires knowing the fine details of its structure — the internal organization and movement that can affect whether it gains energy or loses it — and then plugging those details into an accurate computer model.
Scientists have struggled to do that. They often overestimate strength, which can lead to griping about overpreparedness, as it has with Irene. But they have sometimes underestimated a storm’s power, too, as with (p. D3) Hurricane Charley in 2004. And it is far worse to be underprepared for a major storm.

Berkeley Environmentalist Sticks to Her Knitting

“Avid knitter Shelby Stofle, gathering wool from sheep in Vacaville Calif., hopes to set up a business making scarves and selling them at craft fairs.” Source of caption and photo: online version of the WSJ article quoted and cited below.

(p. A5) Shelby Stofle graduated in December from the University of California at Berkeley with $10,250 in student-loan debt–and no job offers from a dozen applications.

The 24-year-old had hoped to work in environmental conservation or sustainable agriculture but struck out even at a grocery store near her rural hometown of Suisun City, Calif.
. . .
With many employment options exhausted, she said she feels her best shot is to set up her own business, selling her hand-made scarves at craft fairs and farmers’ markets.

Some Traits (Including Some Diseases) Depend on Many Genes Rather than a Single Gene

(p. D3) A new exploration of how evolution works at the genomic level may have a significant impact on drug development and other areas of medicine.
The report, published in Nature last week, offers new evidence in a longstanding debate about how organisms evolve. One well-known path to change is a heavily favorable mutation in a single gene. But it may be well known only because it is easy to study. Another path is exploitation of mildly favorable differences that already exist in many genes.
. . .
Three biologists at the University of California, Irvine, Molly K. Burke, Michael R. Rose and Anthony D. Long, followed populations of fruit flies through 600 generations and studied the whole genome of some 250 flies in order to see what kinds of genetic change they had undergone.
. . .
The conventional view is that evolutionary change is generally mediated by a favorable mutation in a gene that then washes through the whole population, a process called a hard sweep because all other versions of the gene are brushed away. The alternative, called a soft sweep, is that many genes influence a trait, in this case the rate of maturation, and that the growth-accelerating versions of each of these genes become just a little more common. Each fly has a greater chance of inheriting these growth-promoting versions and so will mature faster.
In sequencing their subjects’ genomes, the researchers found that a soft sweep was indeed responsible for the earlier hatching. No single gene had swept through the population to effect the change; rather, the alternative versions of a large number of genes had become slightly more common.
. . .
Haldane favored the single mutation mechanism, but Fisher and Wright backed multiple gene change.
. . .
The demise of the Haldane view “is very bad news for the pharmaceutical industry in general,” Dr. Rose said. If disease and other traits are controlled by many genes, it will be hard to find effective drugs; a single target would have been much simpler.

Power to the People

Source of photo: online version of the NYT article quoted and cited below.

In the Thursday, November 10, 2011 “Home” section of The New York Times, the lead article was about a surge in demand for personal electricity generators among the middle-class of the northeastern United States (places like Connecticut).
Perhaps the lesson is that “green” is a passing fad, but electric power is a necessity in preserving bedrock values such as light, warmth and communication?

(p. D1) WHEN the snowstorm hit a week ago Saturday, Evan Sidel was driving home from the supermarket, having stocked up on soup ingredients, thinking she and her two daughters would have a cozy evening in. But while she was unpacking the groceries, the power went out with an audible bang, said Ms. Sidel, who lives in a 100-year-old farmhouse in Wilton, Conn.
“You could literally hear the transformer exploding,” she said.
Then things went south fast, escalating perilously like the plot of an action movie, or “Spider-Man: Turn Off the Dark” in previews. As Ms. Sidel pulled an old land-line telephone out of the closet, one birch tree crashed into the side of her house and another into her front door.
“I called a friend who said, ‘My generator has just kicked in, come on over.’ I got out through the garage, drove over the lawn to the street, and I stayed at my friend’s house until Wednesday,” she recounted.
. . .
(p. D7) The back story to the recent biblical weather was the Great Generator Divide. With hundreds of thousands of households without power last week — nearly 800,000 in Connecticut alone — who had a generator (and how big it was) was the second most urgent topic in New Jersey, New York and Connecticut. Generator envy ran wide and deep as the staccato growl and smoky breath of portable generators defined the haves and the have-nots in many neighborhoods.
. . .
A few months ago, Mr. Petersheim offered to retrofit the houses he had built in Barryville, N.Y., with standby generators.
“We were seeing more and more power outages in that area,” he said. “And it’s not a super-high-priority area, so the power can stay out for days. Pipes can freeze, food spoils, you can’t get water. It’s become a stress point for our customers. I sent out an e-mail to 20 of them saying, ‘If you’re getting too annoyed with this, it’s pretty affordable, under $7,000 for a 14-kilowatt Generac fueled by propane.’ Seven took us up on it.”
Courtney and Bronson Bigelow (she’s in public relations, he’s a lawyer) were among them. “The first time we had a power outage, it was kind of romantic,” Ms. Bigelow said. “But then it kept happening. When you’re trying to squeeze every second of your weekend, it’s a huge bummer. You can’t wash dishes, you can’t wash yourself, and it’s 20 degrees. This summer we had this freakish weather, torrential rains over Fourth of July, then these weird microburst thunderstorms, and then Irene.”
. . .
Over in Lakeville, Conn., Allen Cockerline, who raises grass-fed cattle with his wife, Robin, at their Whippoorwill Farm, has two large portable generators, 10 and 15 kilowatts each. One runs off his tractor; the other is powered by gasoline. (The tractor-powered one he bought with the farm; the other one cost about $1,500, he said.)
They are a necessary insurance policy for a perishable product, he said: “There’s $30,000 worth of beef in my freezer. I’m not going to let that go.”
But armed as he is against calamity, Mr. Cockerline will admit to some generator envy.
“Everyone that surrounds me is on a much more turnkey situation,” he said. “Theirs just go on automatically. They don’t have to go out and move tractors and generators around.”
“My system is down-and-dirty,” he added, and “in that respect I have a certain amount of envy. But I’m sure my generators are bigger than theirs. Much bigger.”
