As debate roils over EPA regulations proposed this month limiting the release of the potent greenhouse gas methane during fracking operations, a new University of Vermont study funded by the National Science Foundation shows that abandoned oil and gas wells near fracking sites can be conduits for methane escape not currently being measured.

The study, to be published in Water Resources Research on October 20, demonstrates that fractures in surrounding rock produced by the hydraulic fracturing process are able to connect to preexisting, abandoned oil and gas wells, common in fracking areas, which can provide a pathway to the surface for methane.

A recent paper published in the Proceedings of the National Academies of Science showed that methane release measured at abandoned wells near fracking sites can be significant but did not investigate how the process occurs.

A new NASA-led analysis of a moderate magnitude 5.1 earthquake that shook Greater Los Angeles in 2014 finds that the earthquake deformed Earth's crust across a broad region encompassing the northern Los Angeles Basin and northern Orange County. The shallow ground movements observed from this earthquake likely reflect strain accumulated on deeper faults, which remain locked and may be capable of producing future earthquakes.

A team of NASA and university researchers led by geophysicist Andrea Donnellan of NASA's Jet Propulsion Laboratory, Pasadena, California, used GPS and NASA airborne radar data to measure surface deformation in Earth's crust caused by the March 28, 2014, earthquake, which was centered in La Habra, California. The earthquake was felt widely in Orange, Los Angeles, Ventura, Riverside, San Bernardino, Kern and San Diego counties. While the earthquake was relatively moderate in size, the earthquake's depth (3.6 miles, or 5.85 kilometers) and location within a highly populated region resulted in more than $12 million in damage. Most of the damage occurred within a 3.7-mile (6-kilometer) radius of the epicenter, with a substantial amount of damage south of the main rupture.

About 70 million people worldwide stutter when they speak, and it turns out humans aren’t the only ones susceptible to verbal hiccups. Scientists at this year’s Society for Neuroscience Conference in Chicago, Illinois, show that mice, too, can stumble in their vocalizations. In humans, stuttering has long been linked to a mutation in the “housekeeping” gene Gnptab, which maintains basic levels of cellular function. To cement this curious genetic link, researchers decided to induce the Gnptab “stutter mutation” in mice. They suspected the change would trigger a mouse version of stammering. But deciphering stuttered squeaks is no easy task, so researchers set up a computerized model to register stutters through a statistical analysis of vocalizations.

Durante muchos años, y con el avance de la tecnología digital que va velozmente creciendo, seguimos esperando que las oficinas sean sin papeles o como han optado por decir “Paperless”. Pero bien reza un dicho mexicano “es mejor malo por conocido que bueno por conocer” y como las generaciones anteriores nos han heredado un cerro de papeles y un sistema empresarial donde todo tiene que ir impreso y firmado por TRIPLICADO, pues así lo dejamos, para qué nos metemos en líos y problemas de “a gratis”. Así ha sido, así es y así será. Entonces, el avance de la tecnología solo se da en nuestros gadgets, cada vez más sofisticados y en la enorme oportunidad de “Apps” que existen, tanto para IOS como para Android, pero no ingresan en nuestras oficinas y menos en nuestro día a día laboral.

La pregunta es ¿Por qué no? Están al alcance de un clic (literalmente es un clic) pero es difícil cambiar una forma de trabajar, así que el camino para la organización “Paperless” es largo, complicado, consumirá tiempo y recursos (económicos, personales, tecnológicos) pero no es imposible y los beneficios ambientales y económicos son significativos.

Quiero remarcar esto, existen beneficios económicos importantes para las organizaciones que, seriamente, decidan por hacerse de procesos con menos papeles, ...

Fenomenalmente duraderos, los cristales llamados circones son utilizados para fechar algunos de los primeros y más espectaculares cataclismos del sistema solar. Uno de ellos es la súper colisión con la que se expulsó material de la Tierra para formar la Luna, aproximadamente 50 millones de años después de que se formó la Tierra. Otro es el intenso bombardeo tardío, una ola de impactos que pueden haber creado condiciones infernales en la superficie de la joven Tierra, hace unos 4 mil millones de años.

In 2011, satellite images of the African savannas revealed a mystery: these rolling grasslands, with their heavy rainfalls and spells of drought, were home to significantly fewer trees than researchers had expected. Scientists supposed that the ecosystem's high annual precipitation would result in greater tree growth. Yet a 2011 study found that the more instances of heavy rainfall a savanna received, the fewer trees it had.

To this ecological riddle, Princeton University researchers might have finally provided a solution.
