[2010] Do pregnant women need to abstain completely from drinking? - By Libby Copeland
From the standpoint of popular culture, drinking during pregnancy is the equivalent of playing Russian roulette with your fetus. Any woman daring to consume a single glass of wine in public risks being construed as the most unnaturally selfish of mothers. Even as recent studies suggest that science refuses to conclude the case, we cling to the prohibition in a way that precludes discussion. But perhaps that shouldn't be surprising—our reasons may have as much to do with the distinctive morality of pregnancy as they do with science. This month the issue was revived again.

Targeted muscle reinnervation enables your brain to control prosthetic limbs
If you're suddenly overcome with an eerie feeling of déjà vu, fret not, as this idea has certainly been brainstormed before .
Hopkins Applied Physics Lab Awarded DARPA Funding to Test Thought-Controlled Prosthetic Limb System The Defense Advanced Research Projects Agency (DARPA) has awarded a contract for up to $34.5 million to The Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., to manage the development and testing of the Modular Prosthetic Limb (MPL) system on human subjects, using a brain-controlled interface. APL scientists and engineers developed the underlying technology under DARPA's Revolutionizing Prosthetics 2009 program, an ambitious four-year effort to create a prosthetic arm that would by far eclipse the World War II era hook-and-cable device used by most amputees.

Pourquoi, pour dormir la nuit, doit-on se couvrir sans quoi nous avons froid? Ce phénomène s'explique par la baisse de la température du corps dans la phase du sommeil.

The kind of drowning you see on T.V.—think thrashy, screamy—doesn't have much in common with what real drowning looks like, according to writer and Navy/Coast Guard veteran Mario Vittone . That's because of something called the Instinctive Drowning Response, a pattern of behavior that appears to be hard-wired into humans and pops up whenever somebody feels like they're suffocating in water. Frank Pia, Ph.D. , the psychologist and lifeguard to first described the Instinctive Drowning Response explains it this way :
Drowning doesn't look like drowning
Souvent parée de toutes les vertus, l’ADN n’est pas la “ reine des preuves ” : erreurs de manipulation, d’analyse ou de conservation, “ faux positifs “… les annales policières et judiciaires ont d’ors et déjà répertorié plusieurs cas de personnes, accusées et incarcérées, à tort, parce que leur ADN les désignait comme suspectes (voir Quand les “experts” se trompent ). Plusieurs scientifiques tirent aujourd’hui la sonnette d’alarme : les taux d’erreurs seraient bien trop importants. En juin 2010, plusieurs utilisateurs de 23andme, l’une des entreprises proposant de décoder son propre ADN (voir L’avènement de la génomique personnelle ), découvrirent , stupéfaits, qu’ils n’avaient pas le même ADN que leurs enfants, frères, soeurs, parents, ou bien qu’ils étaient noirs, ou asiatiques (alors qu’ils étaient blancs)…

New guide aims to bring sense to the media coverage of drugs | Media
A guide to help prevent the myth-representation of drugs I was expecting to speak at midday today at the launch of an excellent pamphlet The media guide to drugs: Key facts and figures for journalists produced by an organisation called DrugScope . It is a superb, comprehensive piece of work, running to 140 pages, that should prove invaluable to all journalists who write at any time about drugs . Sadly, there are no trains this morning from Brighton to London because of the snow, so I will not be able to attend the launch after all. If I had done so, I would have said that newspapers have had a poor record in reporting on drugs. They have contributed to the widespread misunderstanding about the topic.A free pamphlet about illicit drugs that every reporter should download. - By Jack Shafer
Where do most people get their information about drugs? From the press. And where does the press get its information?

[2010] Epilepsy’s Big, Fat Miracle
We never make exceptions when it comes to Sam and food, though, which means that when temptation takes hold of Sam and he is denied, things can get pretty hairy. Confronted with a gingerbread house at a friend’s party last December, he went scorched earth, grabbing parts of the structure and smashing it to bits. Reason rarely works. Usually one of us has to pry the food out of his hands. Sometimes he ends up in tears.[2010] Variole, le retour
Trente ans après son éradication, le virus de la variole frappe à nouveau en République démocratique du Congo (RDC). Selon une étude de l'Université de Californie à Los Angeles réalisée entre 2005 et 2007 et relayée par la revue espagnole Publico , il s'agirait d'une variante animale transmissible à l'Homme. 760 nouveaux cas ont été détectés dans différentes régions du pays mais le taux de mortalité de cette épidémie reste à déterminer. Il n'existe aucun traitement contre la maladie.La viruela, erradicada en 1977, ha regresado a África en una forma menos peligrosa, pero rodeada de misterio.
