New theoretical ideas and empirical research show that very young children’s learning and thinking are strikingly similar to much learning and thinking in science. Preschoolers test hypotheses against data and make causal inferences; they learn from statistics and informal experimentation, and from watching and listening to others. The mathematical framework of probabilistic models and Bayesian inference can describe this learning in precise ways. These discoveries have implications for early childhood education and policy. In particular, they suggest both that early childhood experience is extremely important and that the trend toward more structured and academic early childhood programs is misguided.

Martin Chalfie thought the Golden Goose Award was a hoax at first. But now that he knows what it is, the Nobel Prize-winning scientist from Columbia University says that receiving the award this Thursday in a ceremony on Capitol Hill in Washington, D.C., will be "a highlight" of his career. Intended to showcase researchers who pursue oddball topics that eventually lead to significant health and economic benefits, the awards were created by a coalition of science organizations (including AAAS, publisher of ScienceInsider) as a playful rejoinder to the "Golden Fleece Awards" awarded by the late Senator William Proxmire (D-WI), who frequently blasted government-funded basic research as a waste of taxpayer dollars.

A new method for measuring distance based on an optical frequency comb has been unveiled by physicists in the Netherlands. The main benefit of the technique, which involves passing the light from an optical comb through a Michelson interferometer and analysing the resulting interference patterns, is that it allows distances to be measured accurately without already knowing the value to within half a wavelength of the light used. The technique could be used to measure the distance between satellites or to make very precise measurements of the dispersion of light in optical materials.

Both claims that I’m about to describe use novel techniques, and their analyses have not been repeated by anyone else. At this point you should understand that both are tentative, and (based on the history of radical claims) the odds are against them. Both might be wrong. That said, both analyses look to me as though they’ve been reasonably well done, and if a mistake has been made, it will require someone far more expert in dark matter studies than I am to point it out.
So let me describe them in turn, to the best of my ability.

The findings come from a study of 199 middle school students who struggle with reading and who participated in a reading improvement class that included Amazon’s Kindle e-reader, said one of the study’s authors, Dara Williams-Rossi, Southern Methodist University, Dallas.
The researchers found that boys consistently had a higher self-concept of their reading skill than girls both before and after using the e-readers. After use of the e-readers, boys’ attitudes about the value of reading improved, while girls’ attitudes declined, said Williams-Rossi, an assistant clinical professor in the Annette Caldwell Simmons School of Education and Human Development at SMU.

Stephen Fry has confirmed he and Sir Ian McKellen will pay a copyright licence fee so a Southampton pub can carry on trading as The Hobbit.
The pub was threatened with legal action by Hollywood film firm the Saul Zaentz Company (SZC) which accused it of copyright infringement.
It later offered to resolve the dispute over the pub's name and decor by licensing it to use JRR Tolkien brands.

The Hebrew University of Jerusalem, which owns the German Jewish physicist's papers, is pulling never-before seen items from its climate-controlled safe, photographing them in high resolution and posting them online – offering the public a nuanced and fuller portrait of the man behind the scientific genius.
Only 900 manuscript images, and an incomplete catalogue listing just half of the archive's contents, had been available online since 2003. Now, with a grant from the Polonsky Foundation UK, which previously helped digitise Isaac Newton's papers, all 80,000 items from the Einstein collection have been catalogued and enhanced with cross referencing technology.
The updated web portal, unveiled on Monday, features the full inventory of the Einstein archives, publicising for the first time the entirety of what's inside the collection and giving scholars a chance to request access to items they previously never knew existed.

The proportion of doctoral students who find academic jobs is greater than the proportion with a definite aspiration to do so - except in the arts and humanities.
This is the surprising finding of a major survey of PhD students' career aspirations carried out by Vitae, the research careers organisation.
The online survey, carried out in 2010, attracted more than 4,500 responses from doctoral researchers across 130 UK universities and research institutes.
An overwhelming majority of respondents had entered doctoral study for reasons of intellectual curiosity, and only about a third had formed definite career plans, even by the latter years of their doctorates.
Physical science and engineering students were particularly unlikely to have definite plans, while those from the humanities were the most likely.
