Tres Principios Exitosos de la Eco-Eficiencia
January 30, 2017 12:02 PM - Mario Amador, oficina Verde, México

Cuando se habla acerca de eco eficiencia en empresas se debe, necesariamente considerar diversos aspectos, más allá de solo los más evidentes: agua, energía, residuos. Es necesario voltear a ver el compromiso y cultura de los empleados. Si deseamos que se haga un uso responsable de los recursos al interior de la organización es vital que este mismo cuidado se tenga fuera de las actividades cotidianas de los empleados, por supuesto que analizar esto es una tarea titánica, pero quien dijo que mejorar una cultura es sencillo, a veces toma dos o tres generaciones, así que si nuestro objetivo fue reducir en un 20% la impresión en un año o en un 10% el consumo de energía en el área, es mejor que leamos este artículo y ver como lo podemos replantear, no decimos que sea imposible solo que debemos de considerar muchos más elementos y no solo los técnicos.
Según la definición del Programa Ambiental de las Naciones Unidas (UNEP por sus siglas en inglés), la eco eficiencia es “la aplicación continua de una estrategia preventiva e integrada a los procesos tendiente a reducir los riesgos para los humanos y el ambiente”, se puede aplicar en sector comercial, industrial y servicios para incrementar la competitividad de las organizaciones.

 

Artificial Intelligence Is About to Conquer Poker, But Not Without Human Help
January 24, 2017 08:41 AM - Cade Metz, Wired

As Friday night became Saturday morning, Dong Kim sounded defeated.

Kim is a high-stakes poker player who specializes in no-limit Texas Hold ‘Em. The 28-year-old Korean-American typically matches wits with other top players on high-stakes internet sites or at the big Las Vegas casinos. But this month, he’s in Pittsburgh, playing poker against an artificially intelligent machine designed by two computer scientists at Carnegie Mellon. No computer has ever beaten the top players at no-limit Texas Hold ‘Em, a particularly complex game of cards that serves as the main event at the World Series of Poker. Nearly two years ago, Kim was among the players who defeated an earlier incarnation of the AI at the same casino. But this time is different. Late Friday night, just ten days into this twenty-day contest, Kim told me that he and his fellow humans have no real chance of winning.

Measuring the 'true social cost' of carbon dioxide emissions
January 13, 2017 08:32 AM - University of Oxford

The US National Academies of Sciences, Engineering, and Medicine has proposed a new framework for US agencies to use to estimate the 'social cost of carbon dioxide' emissions. Myles Allen, Professor of Geosystem Science at the Environmental Change Institute, helped compile the report which will strengthen the scientific basis and provide greater transparency for US climate policy.

January 12, 2017 09:26 AM -

Authorities in Beijing are taking new actions to resolve the city’s ongoing and harmful air pollution problem with the creation of an anti-smog police force — but will it help?

Farthest Stars in Milky Way Might Be Ripped from Another Galaxy
January 11, 2017 12:14 PM - Harvard-Smithsonian Center for Astrophysics

The 11 farthest known stars in our galaxy are located about 300,000 light-years from Earth, well outside the Milky Way's spiral disk. New research by Harvard astronomers shows that half of those stars might have been ripped from another galaxy: the Sagittarius dwarf. Moreover, they are members of a lengthy stream of stars extending one million light-years across space, or 10 times the width of our galaxy.
