(credit: Charité, Carsten Bogler)] Neuroscientists run the ultimate experiment to find out: a "duel" between human and brain-to-computer interface (BCI) It’s a question that’s been debated by philosophers for centuries. Now neuroscientists from Charité –Universitätsmedizin Berlin have run an experiment to find out, using a “duel” game between human and brain-computer interface (BCI). As KurzweilAI reported last year: In the early 1980s, University of California, San Francisco neurosci... mais »

Poesia
*Como já foi dito que seremos salvo pela ARTE e não pela CIÊNCIA, compartilho uma poesia enviada por um colega e AMICOR de Buenos Aires: * Dr.Alejandro Wajner Le envio un texto una poesia que le escribi a mis hijos y que creo que usted compartira.

Dark matter
*From MACHOs to WIMPs: meet the top five candidates for ‘dark matter’* December 14, 2015 8.33am EST When we look out at the universe – even with the most powerful of telescopes – we can only see a fraction of the matter we know must be there. In fact, for every gram’s worth of atoms in the universe, there is at least five times more invisible material called “dark matter”. So far scientists have failed to detect it, despite spending decades searching. The reason we know it exists is because of the gravitational pull of galaxy clusters and other phenomena we observe. The matter we can s... mais »

The Sugar-Cancer Connection This article appears in the January 7, 2016 issue of AICR's eNews. [image: sugar on table] Does sugar feed cancer? It’s one of the questions we get asked often.

Health for all
From: Bruno Gryseels “Health Care for All” was defined fifteen years ago at a high-level meeting in Antwerp in October 2001, as an updated version of Alma Ata’s “Health for all”. The gathering of ministers of health, UN organizations and academia discussed the need for strong health care systems in the conceptualization of the Global Fund, which at that time was still embryonic. All ministers of health reaffirmed primary health care as their first and foremost priority, as a human right and as a precondition for sustainable disease control. International organiz... mais »

The nineteenth-century Russian chemist was the youngest of 11 siblings—unless it was 13 or 14 or maybe 16. No one ever knew, and he never clarified things for his many biographers. But then he had much bigger—and, on an elemental s... mais »
