Mapping America’s Restless Interstate Migration Without a Map - Wired Science
▻http://www.wired.com/wiredscience/2013/11/mapping-migration-without-a-map
There is a temptation with any kind of data that has a geographical aspect to display it on a map. While maps are by far the best way to convey many of these data, sometimes they are not. This is one of those times.

Even though data on migration between states would seem to cry out to be mapped, this circular visualization by independent data journalist Chris Walker (@cpwalker07) can convey a lot of information far more neatly than a map. Patterns leap out that might have been obscured on a single map, or required many maps to convey the same information

“It’s useful to think beyond maps especially for cases where you want to show interconnectedness between regions, which is what I was trying to do,” Walker wrote in an email to WIRED.
Presque tout le poulet américain est contaminé
▻http://www.lefigaro.fr/flash-actu/2013/12/19/97001-20131219FILWWW00537-presque-tout-le-poulet-americain-est-contamine.ph
La quasi totalité du poulet acheté en grandes surface est contaminée par des bactéries dangereuses comme la salmonelle ou l’e-coli, affirme l’influent magazine de consommateurs américain Consumer Report dans une enquête publiée aujourd’hui.
Cet équivalent du magazine français 60 Millions de Consommateurs explique que « l’analyse de 300 blancs de poulet crus achetées dans des magasins à travers les Etats-Unis a mis en évidence des bactéries potentiellement dangereuses dans presque tous les poulets, y compris les marques biologiques ».
« Plus de la moitié des échantillons », achetés en juillet, « contenaient des matières fécales contaminantes » et « environ la moitié contenaient au moins une bactérie résistante à trois ou quatre antibiotiques parmi les plus couramment prescrits », détaille l’article.
Le magazine souligne qu’aucune chaîne de distribution ni aucune marque sur des dizaines testées (Wal-Mart, Tyson, America’s Choice, Whole Foods, Traders’ Joe...etc.) n’est épargnée.
Il met particulièrement à l’index la marque Foster Farms dont trois usines du sud-ouest américain sont à l’origine d’une épidémie de salmonelle particulièrement virulente intervenue cet été aux Etats-Unis, et qui n’a pas lancé de rappel.
« Qu’est-ce qui ne va pas avec la viande préférée des Américains ? » interroge le magazine, qui rappelle que les Américains consomment 40 kilos de poulet par tête en moyenne chaque année.
Drug-Resistant Bacteria on Chicken: It’s Everywhere and the Government Can’t Help

Short version: Independent tests show that multi-drug resistant disease-causing bacteria are widely present on chicken, and the US Department of Agriculture’s Food Safety and Inspection Service (FSIS) has insufficient personnel, or legal authority, to change that.

Before modern copyright laws there were no legal or even cultural barriers to borrowing content, Cordell says. Newspapers borrowed freely. Large papers often had an “exchange editor” whose job it was to read through other papers and clip out interesting pieces. “They were sort of like BuzzFeed employees,”

Adventures in Mapmaking : How to Map the Age of Buildings in Your Hometown - Wired Science
▻http://www.wired.com/wiredscience/2013/10/how-to-map-building-ages-in-your-home-town
You may have seen some of the beautiful maps of building ages that have been cropping up around the internet. I first noticed an amazing one of Portland, and then another great one of Brooklyn. I decided I wanted to try to make one of San Francisco, but, as I still know very little about making maps, I knew I’d need help.
So I called up Thomas Rhiel of the independent journalism site BKLYNR.com. Rhiel was willing to help, and it turns out he was just the right person to advise me. His map of Brooklyn building ages was his first foray into mapmaking, so he had just muddled his way down the same path I was about to navigate.
I’m going to tell you exactly how I made this map. I hope that people with little or no experience making maps will be able to use this as a guide to getting started on a map of their own hometown. And I also hope expert mapmakers will chime in to tell us how we can improve our maps.

Filling in the gaps: slum mapping
It’s also been a problem with inner city slums where “the quality of the mapping is often rather poor”, says Sliuzas.
“In some cities, these areas are quite well mapped and quite well monitored. In Sao Paulo in Brazil, for example, they have a very big program. All of the data has been collected, it’s online, it’s monitored regularly — but that’s unusual, there are many many cities where people don’t know at all what the situation is.”
(...)
Many would argue that it lies to the state to make sure these areas are properly mapped and understood, but there have been cases where slums have been deliberately left off maps because authorities don’t consider them formal parts of the city. This results in a situation where everyone knows there are slums in the city, but nobody can see them when they look at a map, says Sliuzas, who has dedicated his career to studying areas of urban poverty and informal settlements.
Maps of Unrealized City Plans Reveal What Might Have Been
Maps can direct us from here to there, show where one thing is in relation to another, or add layers information to our surroundings. Whatever its form, a map’s main purpose is to make the complex world we live in more comprehensible.

Why Are Some People So Smart? The Answer Could Spawn a Generation of Superbabies - Wired Science
▻http://www.wired.com/wiredscience/2013/07/genetics-of-iq
Zhao’s goal is to use those machines to examine the genetic underpinnings of genius like his own. He wants nothing less than to crack the code for intelligence by studying the genomes of thousands of prodigies, not just from China but around the world. He and his collaborators, a transnational group of intelligence researchers, fully expect they will succeed in identifying a genetic basis for IQ.
They also expect that within a decade their research will be used to screen embryos during in vitro fertilization, boosting the IQ of unborn children by up to 20 points.
...
In theory, that’s the difference between a kid who struggles through high school and one who sails into college.But studies make it clear that IQ is strongly correlated with the ability to solve all sorts of abstract problems, whether they involve language, math, or visual patterns.
The frightening upshot is that IQ remains by far the most powerful predictor of the life outcomes that people care most about in the modern world. Tell me your IQ and I can make a decently accurate prediction of your occupational attainment, how many kids you’ll have, your chances of being arrested for a crime, even how long you’ll live.

L’industrie spatiale en plein essor
(Checklist du Monde, 22 juin 2013)
Le secteur spatial est en plein boom. Le chiffre d’affaires a progressé de 7 % en 2012, à 189,5 milliards de dollars, nettement plus rapidement que la croissance mondiale, selon un rapport de la Satellite Industry Association (SIA). L’Europe tire bien son épingle du jeu dans ce #marché en expansion.

CDC Warns of Resistance ’Nightmare’ | Wired Science | Wired.com
▻http://www.wired.com/wiredscience/2013/03/cre-cdc
The underlying risk here is that effectively untreatable CRE will spread out from hospitals and into the wider world, where it will become vastly more common and much harder to detect. That is not an unreasonable fear (...)
So what’s to be done? In their press push yesterday, the CDC reviewed six steps that they first published last year in a CRE Toolkit and want health care facilities to take (...) an important point is that none of this is required, and none of this is funded.

Chief Medical Officer Dame Sally Davies : Resistance to antibiotics risks health ’catastrophe’ to rank with terrorism and climate change
▻http://www.independent.co.uk/news/science/chief-medical-officer-dame-sally-davies-resistance-to-antibiotics-ris
The reason, Dame Sally says, is market failure – for Big Pharma, there is little money in expensively developing new compounds which will only be taken in short courses, compared to a drug for blood pressure, say, which may have lifelong use for patients. Addressing the “discovery void” is now the key problem, she says, which may have to be tackled internationally, and may involve governments intervening in the hitherto private sector of drug development.
“We may have to work with the pharmaceutical companies in public-private partnerships, and we may have to do some development of antibiotics on a public basis,” she said.
She gave the example of the Innovative Medicines Initiative, a joint undertaking between the European Union and the pharmaceutical industry which supports collaborative research to boost pharmaceutical innovation in Europe.
#Polio Eradication : The Bad News Continues | Wired
►http://www.wired.com/wiredscience/2013/01/polio-more-bad
The crisis in Pakistan is not just about the changeable fortunes of the polio campaign, which has waxed and waned in public opinion since its launch in 1988. It is specifically in response to the admitted-to ruse by the CIA, which used a pretense of administering injectable hepatitis B vaccine in an attempt to harvest DNA from children who were believed to be related to bin Laden, as a way of proving he was in a particular area. They did not succeed – his location was proven by other means — but the damage to public heath looks to be long-lasting.
So long-lasting, in fact, that the deans of 12 public-health schools in the United States (Columbia, Emory, Harvard and others) have sent an open appeal to President Obama excoriating the CIA attempt and asking that it never happen again.
