    No cetacean mass stranding in the Canaries since military sonar ban in 2004

    Prompt political action may have resulted in a remarkable conservation success for whales and dolphins. The Canary Islands used to be a hotspot for mass strandings, but there have been no mass beachings since the Spanish government imposed a moratorium on naval exercises in these waters in 2004.

    Water pollution from sewage is causing great damage to India. The nation needs to complete its waste systems and reinvent toilet technologies, says Sunita Narain.

      Site d’information sur la gestion durable de l’eau dans le monde, basé sur les travaux de Josef Orszag

      Lorsqu’on envisage la gestion durable de la biosphère, la destruction massive des déjections humaines sous prétexte d’épuration est une forme de suicide collectif. En ce sens, le principe même de l’épuration des eaux fécales, quel que soit le système utilisé, est incompatible avec le concept du développement durable.

    Alan Turing at 100
    http://www.nature.com/news/specials/turing/index.html

    Alan Turing, born a century ago this year, is best known for his wartime code-breaking and for inventing the ’Turing machine’ – the concept at the heart of every computer today. But his legacy extends much further: he founded the field of artificial intelligence, proposed a theory of biological pattern formation and speculated about the limits of computation in physics. In this collection of features and opinion pieces, Nature celebrates the mind that, in a handful of papers over a tragically short lifetime, shaped many of the hottest fields in science today.

      Turing was driven by the dream of reviving — possibly in the form of a computer program — the soul of Christopher Morcom, perhaps his only true friend, who died abruptly when they were both teenagers.

    WHO meeting calls for mutant-flu research to be published ‘in full.’
    http://blogs.nature.com/news/2012/02/who-meeting-calls-for-mutant-flu-research-to-be-published-in-full.html

    A two-day meeting of 22 experts convened in Geneva by the World Health Organization (WHO) has concluded that two controversial flu studies should be published in full. The research — in which ferret-transmissible strains of avian H5N1 flu virus were created — will be published after a delay of probably a few months, which the experts argue is needed to explain better the public-health benefits of the research and allay public concerns over the safety of the work

    Configuring scholarly communication infrastructure for the next generation of researchers requires getting into the heads of current undergraduates and graduate students. Their life experience is of immediate online availability and global search engines, and they arrive imbued with the social-network mentality of sharing links, photos, videos and status updates. Yet, my own informal survey of graduate students reveals information-gathering techniques familiar to most older scientists. Students still follow citation trees, search by keywords and consult with peers and mentors, with the latter as important as ever for weeding out unreliable sources. Students also say that they search preferentially for open-access resources when working from home, because accessing subscription-based journals, even when available through an institutional proxy, can be frustratingly painful.

    L’histoire des dépôts d’articles scientifiques. J’avais envie de tout citer. Un must indispensable.

    Twenty years ago this month, I launched an electronic bulletin board intended to serve a few hundred friends and colleagues working in a subfield of theoretical high-energy physics.

    Even today, fields vary hugely in how they recognize intellectual precedence. It baffles me that scientists in some fields can announce a result in a public forum, such as a meeting, while another group can reproduce the results, publish first in a journal, and be given complete intellectual precedence, as though the information did not exist until vetted by the referee process. Journal editors and referees should make more effort to ensure proper attribution is given to publicly accessible materials in a stable resource, such as arXiv.

    Again, because of cost and labour overheads, arXiv would not be able to implement conventional peer review. Even the minimal filtering of incoming preprints to maintain basic quality control involves significant daily administrative activity. Incoming abstracts are given a cursory glance by volunteer external moderators for appropriateness to their subject areas; and various automated filters, including a text classifier, flag problem submissions. Although the overall rate of such submissions is well below 1%, they tend to cluster in specific areas (such as general relativity, quantum mechanics and unified theories in physics; proofs of the Riemann hypothesis, Goldbach’s conjecture and new proofs of Fermat’s last theorem in mathematics; P versus NP problem in computer science).

    Moderators, tasked with determining what is of potential interest to their communities, are sometimes forced to ascertain ’what is science?’ At this point arXiv unintentionally becomes an accrediting agency for researchers, much as the Science Citation Index became an accrediting agency for journals, by formulating criteria for their inclusion. Although decisions are biased towards permissiveness, inevitably some authors object that it is never permissive enough.

    Configuring scholarly communication infrastructure for the next generation of researchers requires getting into the heads of current undergraduates and graduate students. Their life experience is of immediate online availability and global search engines, and they arrive imbued with the social-network mentality of sharing links, photos, videos and status updates.

    Students also say that they search preferentially for open-access resources when working from home, because accessing subscription-based journals, even when available through an institutional proxy, can be frustratingly painful.

    On arXiv, we have seen some of the unintended effects of an entire global research community ingesting the same information from the same interface on a daily basis. The order in which new preprint submissions are displayed in the daily alert, if only for a single day, strongly affects the readership on that day and leaves a measurable trace in the citation record fully six years later2, 3. Some researchers, wise to this, time their submissions to arrive just after the daily afternoon deadline to maximize their prominence in the next day’s mailing.

    Climate change and the resurgence of #malaria in the East African highlands : Abstract : Nature
    http://www.nature.com/nature/journal/v415/n6874/abs/415905a.html

    Climate Change [...] there is likely to be a net extension in the distribution of malaria and an increase in incidence [...]. We investigated long-term meteorological trends in four high-altitude sites in East Africa, where increases in malaria have been reported in the past two decades. Here we show that temperature, rainfall, vapour pressure and the number of months suitable for P. falciparum transmission have not changed significantly during the past century or during the period of reported malaria resurgence.
