Photo 51 – Wikipedia, the free encyclopedia

Sunday, June 12th, 2016

QT:{{”

Photograph 51 is the nickname given to an X-ray diffraction image of DNA taken by Raymond Gosling in May 1952, working as a PhD student under the supervision of Rosalind Franklin,[1][2][3][4] at King’s College London inSir John Randall’s group. It was critical evidence[5] in identifying the structure of DNA.[6]

James Watson was shown the photo by Maurice Wilkins without Rosalind Franklin’s approval or knowledge (although by this time Gosling had returned to the supervision of Wilkins). Along with Francis Crick, Watson used characteristics and features of Photo 51 to develop the chemical model of the DNA molecule. In 1962, the Nobel Prize in Physiology or Medicine was awarded to Watson, Crick and Wilkins. The prize was not awarded to Franklin; she had died four years earlier, and the Nobel Prize’s rules require that it be awarded only to living persons.[7]

The Avery–MacLeod–McCarty experiment was an experimental
demonstration, reported in 1944 by Oswald Avery, Colin MacLeod, andMaclyn McCarty, that DNA is the substance that causes bacterial transformation, in an era when it had been widely believed that it wasproteins that served the function of carrying genetic information (with the very word protein itself coined to indicate a belief that its function was primary).

The paradox arises because numbers of friends people have are distributed in a way that follows a power law rather than an ordinary linear relationship. So most people have a few friends while a small number of people have lots of friends.

In dramatic statement, European leaders call for ‘immediate’ open access to all scientific papers by 20 20

European leaders call for immediate #OpenAccess to all sci papers by

“goal is part of a broader set of recommendations in support of open science, a concept that also includes improved storage of and access to research data. The Dutch government, which currently holds the rotating E.U. presidency, had lobbied hard for Europe-wide support for open science, as had Carlos Moedas, the European commissioner for research and innovation.
….
We probably don’t realize it yet, but what the Dutch presidency has achieved is just unique and huge,” Moedas said

He is known chiefly for suggesting the concept of genes, rediscovering the laws of heredity in the 1890s while unaware of Gregor Mendel’s work, for introducing the term “mutation”, and for developing a mutation theory of evolution.

A Disabilities Program That ‘Got Out of Hand’

Tuesday, May 17th, 2016

QT:{{"

“By 1992, half of Dalton’s students entering fourth grade had already received remedial help. Several Dalton teachers describe their classrooms as being overrun by specialists. One teacher, who had half her class diagnosed with learning problems, says she simply gave up arguing with the specialists and used the Fisher Landau program for her entire class.

Other teachers battled back, refusing to let the specialists in their rooms. When teachers gathered, they joked about how long it would be before the entire primary school was diagnosed with learning disabilities. Jeannie Wang, a former Dalton kindergarten teacher, said: "If you dig hard enough in any kid, you’ll find a problem. If you want to have something to write down, you’ll find something to write down."

Then, in fall 1992, it abruptly ended. The kindergarten teachers revolted and refused to use the screening test, saying too many children were being given harmful and unreliable labels. Naomi Hill, the new primary school principal with a different educational philosophy, dismantled much of the Fisher Landau program.

Instantly, learning disabilities at Dalton plummeted. This year, half a dozen kindergartners are getting extra help from specialists; about 15 percent in first through third grades receive help.

That such a major shift could occur twice in one place in a decade is a stunning commentary on how subjective the identification of learning disabilities can be and how little is known about them. Did It Help?

Despite the hundreds of thousands of dollars Mrs. Landau paid the universities, no one today can say with objective certainty whether the remedial program actually helped Dalton students. "We can’t answer that question," said Steven Peverly, one of three Columbia researchers who worked four years on the project. "In the field of education there’s this problem with research. People don’t think about setting up controls. It’s not like science."”

Why Aren’t There More Scientists? A One-Word Explanation

Q: Why Aren’t There More Scientists? A: Money
http://phenomena.nationalgeographic.com/2016/04/29/why-we-dont-produce-more-scientists-a-one-word-explanation/ Breakdown of how a field’s $6M in NSF #funding is apportioned HT @gnat

QT:{{”
“Every year Congress gives the National Science Foundation roughly 7.3 billion dollars. That sum hasn’t changed much (in real terms) for decades. The Defense Department gets $573 billion. But $7.3 billion isn’t bad. “It sounds like a lot of money,” says Jahren, even if it’s spread across biology, geology, chemistry, mathematics, physics, psychology, sociology, and some computer science.
Divided 50 times—assuming one paleobiologist in every state—that works out to $120,000 per grant. In fact, Jahren counted between 30 and 40 grants per year, for an average of $165,000. Assuming some of those scientists hire assistants, she figures there are “about 100 [government] funded paleobiologists in America.””

Among the installations is a “lunch button” kiosk, which matches up employees with common interests to have lunch together that day. And there is a “conversation portal”—a two-way videoconferencing system attached to the end of a long cafe table—to help “spark informal conversation” among diners from offices around the world, Mr. Rose says. Another is a “conversational balance table” where an animated floral display provides instant feedback on whether someone is hogging a conversation.

…Schrot sent an e-mail to Robert Nelson, a pediatric ethicist and oncologist at the F.D.A., describing the procedure and asking for advice. Nelson replied quickly. “If the product”—Enterobacter—“you plan to use is available to you,” he wrote, in part, “I would suggest you proceed under the strategy of innovative treatment rather than research.”
