Comment Vivre en temps de crise ?

27 Nov

It is not the economic crisis, it is only the most sensitive part of a wholeCommentVivre systemic crisis involving culture, civilization processes, the correct understanding of the use of technology, and above all and mainly that is being who we are.

The book by Edgar Morin and Patrick Viveret, philosopher and former counselor of the government of Auditors Jospin an important mission which was to redefine what are in fact the indicators of wealth.

Viveret authority is it because Réconsidérer wrote it Richesse (Éditions de l’Aube) and Pourquoi ça ne vas pas mal plus? (Fayard), but the partnership with Morin makes this significant fact speech for the moment we live on the planet.

Just when everything seems to apply for disaster, perhaps this is just a superficial view of a changing world with many interesting opportunities.

We must be ready to welcome the unlikely, and this can only happen to those who are attentive to positive use this crisis as a new opportunity for a new relationship with the democratic power, monetary wealth, but rather with what can make sense to all that we are living and witnessing.

A Europe also Arab and black, an America that embraces and change the lives of the poor, without corruption, dictatorships and ideological biases, all this seems unlikely, but …

What Morin and Viveret deny are the conventional models, the already matured polarization and simplistic reasoning … the improbable can happen: a new era.


Ciência Aberta e Redes sociais

26 Nov

Ciência Aberta (Open Science) é referente a uma nova tendênciaCienciaAberta na prática científica, que a partir do desenvolvimento e com apoio da cultura digital, disponibiliza informações e dados em acesso aberto de forma oposta a pesquisas fechadas em grupos e laboratórios.
Neste contexto a revisão por pares, como o Peerage of Science, o arXiv e a a PLoS confirmam essa tendência que agora desponta também nas redes sociais.
Um exemplo do uso de redes sociais foi o estudo antimalária do pesquisador americano Jean-Claude Bradley e seus alunos.
Eles compartilham informações sobre tudo o que produzem na pesquisa da Drexel University, na Filadélfia, cujo objetivo é desenvolver compostos orgânicos úteis para a prevenção ou para a cura dessa doença que mata mais de 1 milhão de pessoas por ano no mundo.
Bradley usou o modelo de “wikis” para desenvolver o compartilhamento de dados em redes sociais, e foi na esteira desta pesquisa que nasceu o Creative Commons – fundado em 2001 nos Estados Unidos, visando ampliar o compartilhamento e uso do conhecimento por meio de licenças que que liberam o copyright (todos os direitos reservados) em áreas exclusivas para discutir ciência.
A USP realiza nestes dias o o Encontro de Ciência Aberta, com diversas oficinas, palestras e uma mesa redonda para ampliar este horizonte no país passar a incorporar a iniciativa internacional chamada OpenCon.
As inscrições são gratuitas, com oficinas na ECA, CCSL na Matemática da USP e no Garoa Hacker Club.


Nature and a cure for cancer

The brazilian social debate after a court order requiring the USP to provide aFosfoetanolamina miracle cure for cancer healing, phosphoethanolamine, the USP contested, now comes the prestigious scientific journal Nature, which defends the position of USP.
The last issue of the magazine brings along with an paper, the reconstitution of the way of the substance, from its preparation and an alleged efficacy, yet inconclusive tests until its unofficial distribution and because the Brazilian court decided to intervene to limit their circulation due to clinical tests are required to be distributed.

The compound, phosphoethanolamine f, has been shown to kill tumour cells only in lab dishes and in mice (A. K. Ferreira et al. Anticancer Res. 32, 95–104; 2012). Drugs that seem promising in lab and animal studies have a notoriously high failure rate in human trials.

Despite this, some chemists at the University of São Paulo’s campus in São Carlos have manufactured the compound for years and distributed it to people with cancer. A few of those patients have claimed remarkable recoveries, perpetuating the compound’s reputation as a miracle cure.
