Freeman Dyson — the world-renowned mathematical physicist who helped found quantum electrodynamics with the bongo-playing, Nobel Prize-winning physicist Richard Feynman and others, devised numerous mathematical techniques, led the team that designed a low-power nuclear reactor that produces medical isotopes for research hospitals, dreamed of exploring the solar system in spaceships propelled by nuclear bombs, wrote technical and popular science books, penned dozens of reviews for The New York Review of Books, and turned 90 in December — is pondering a new math problem.

This June, Sotheby’s will be auctioning off the Macdonald viola, created in 1719 by the legendary Italian violin-maker Antonio Stradivari. They’re asking for a minimum bid of $45 million, which would make this viola the most expensive instrument ever sold.

This price tag may break records but Stradivari’s instruments often fetch millions of dollars, due to both the cachet of the name and their reputed quality. Many people genuinely believe that they are superior to newly made violins and many scientists have tried to work out why.

But to Claudia Fritz from Sorbonne University, the search for Stradivari’s secrets is a “perennially fruitless one”… because they don’t exist. In two studies, she has shown that professional violinists can’t tell the difference between the so-called “Old Italian” violins and newly made ones.

A young researcher who shot to fame in scientific circles when she published an apparently radical and simple way to create stem cells has been found guilty of misconduct by a committee charged with investigating her work.

Haruko Obokata, at the Riken Centre for Developmental Biology in Kobe, announced the breakthrough in January in two articles published in the scientific journal Nature, but the discovery was thrown into doubt after researchers elsewhere failed to replicate her work.

The ruling has not settled the debate over whether her breakthrough was real, though. In a bizarre twist in an already convoluted story, the committee's ruling against Obokata came moments before an independent researcher claimed to have succeeded in making the cells using a slightly different procedure.
Committee in Japan says it found evidence of falsification and fabrication – offences that constitute research misconduct

Right. At the moment, this is the result of a general inquiry on Obokata's research practices. However, it doesn't say anything on the claimed stem cell discovery.

Very well-written explanation of frequentist and bayesian approaches to statistical inference.

One of the first things a scientist hears about statistics is that there is are two different approaches: frequentism and Bayesianism. Despite their importance, many scientific researchers never have opportunity to learn the distinctions between them and the different practical approaches that result. The purpose of this post is to synthesize the philosophical and pragmatic aspects of the frequentist and Bayesian approaches, so that scientists like myself might be better prepared to understand the types of data analysis people do.

I'll start by addressing the philosophical distinctions between the views, and from there move to discussion of how these ideas are applied in practice, with some Python code snippets demonstrating the difference between the approaches.

nice that it also has accompanying code to work through step by step !

No one ever says "The unemployment rate has dropped by 0.1% for no apparent reason."
When watching the TV news, or reading newspaper commentary, I am frequently amazed at the attempts people make to interpret random noise. For example, the latest tiny fluctuation in the share price...

When she's experiencing hallucinations, artist Sue Morgan feels compelled to draw; to 'get it out of her head'. Sue was diagnosed with schizophrenia about 20 years ago. The drawing is therapeutic, but it's also Sue's way of expressing the complex and sometimes frightening secret world in her head. In this film Sue meets Sukhi Shergill, a clinician and researcher at the Institute of Psychiatry in London. He's also making pictures, but using MRI to peer inside the brains of schizophrenia patients.

A report by the Senate Intelligence Committee concludes that the CIA misled the government and the public about aspects of its brutal interrogation program for years — concealing details about the severity of its methods, overstating the significance of plots and prisoners, and taking credit for critical pieces of intelligence that detainees had in fact surrendered before they were subjected to harsh techniques.

The report, built around detailed chronologies of dozens of CIA detainees, documents a long-standing pattern of unsubstantiated claims as agency officials sought permission to use — and later tried to defend — excruciating interrogation methods that yielded little, if any, significant intelligence, according to U.S. officials who have reviewed the document.
Investigators conclude that the agency overstated the effectiveness of harsh tactics while hiding details and taking credit where it wasn’t due.
