The end of December marks the end of spring and beginning of summer along the coast of East Antarctica. The Sun shines most (if not all) of the time, yet ice still dominates the land and sea. That ice, however, is far from uniform. Varied forms of ice appear in these images from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite and the Advanced Land Imager (ALI) on NASA's Earth Observing-1 (EO-1) satellite.

These natural-color images both show parts of the Mawson Coast, where an Australian-led research station is located. The MODIS image (from December 16, 2011) offers a wide-area view and the ALI image (December 30) gives a close-up centered around the research station. Along the ice-encrusted coastline floats a broad band of fast ice, which derives its name from the fact that it holds fast to the shore. This thick ice is lighter in color than the thinner sea ice farther offshore (visible in the wide-area view). NASA's 64-megapixel photo of Earth. 2012 January 13 - Saturns Iapetus: Painted Moon.

Sal Khan es un pionero en la educación digital. Y no lo digo yo, sino Bill Gates. Hacer que uno de los hombres más influyentes del mundo en el último cuarto de siglo piense eso de ti tiene que estar fundamentado. Y vaya que el trabajo de Sal en los últimos años ha valido la pena. Todo comenzó como un problema familiar.

En 2004, mientras su familia de Nueva Orleans lo visitaba en Boston. Sal se enteró que Nadia, su prima de 12 años, necesitaba quien le ayudará a entender los problemas matemáticos de las conversiones de unidades. Sal se ofreció a ayudarla, pero el problema era la distancia. Una vez que Nadia regresó a Nueva Orleans, Khan comenzó a llamarla por teléfono para explicarle mientras usaba Yahoo Doodle como cuaderno de trabajo común. Esta historia fue el origen de lo que se ha convertido en una revolución educativa: Khan Academy.

Una verdadera escuela virtual que a la fecha ha dado más de 45 millones de clases alrededor del mundo. Bill Gates, alumno destacado de Khan Academy Involúcrate. Consignan a cibernautas por terrorismo en Veracruz - El Universal - Los Estados. Xalapa, Veracruz | Domingo 28 de agosto de 2011Édgar Ávila Pérez / Corresponsal | El Universal10:32 Dos cibernautas fueron consignados ante un juez como probables responsables de los delitos de terrorismo y sabotaje, pues son señalados por el Gobierno de Veracruz de generar rumores falsos en las redes sociales que provocaron temor el pasado miércoles en las ciudades de Veracruz y Boca del Río. El Ministerio Público consideró tener suficientes pruebas contras los dos cibernautas, entre ellos una ex funcionaria del anterior gobierno, por lo que decidió consignarlos ante un juez, quien decidirá si son culpables o inocentes.

Las dos personas son señalas de haber iniciado rumores el pasado miércoles sobre presuntos ataques del narcotráfico en contra de escuelas públicas de la zona turística de Veracruz y Boca del Río. La Agencia Veracruzana de Investigaciones (AVI) logró ubicar las cuentas y usuarios iniciales que generaron estas actividades y que propagaron los falsos mensajes. Adictos a la comunicación.

Instalación sobre el agua. Know and show what you got! - TwentyFeet - TwentyFeet Wiki. Are We Prepared for a Catastrophic Solar Storm? Breakthroughs, discoveries, and DIY tips sent six days a week. One of the biggest disasters we face would begin about 18 hours after the sun spit out a 10-billion-ton ball of plasma–something it has done before and is sure to do again.

When the ball, a charged cloud of particles called a coronal mass ejection (CME), struck the Earth, electrical currents would spike through the power grid. Transformers would be destroyed. Lights would go out. Food would spoil and–since the entire transportation system would also be shut down–go unrestocked. Within weeks, backup generators at nuclear power plants would have run down, and the electric pumps that supply water to cooling ponds, where radioactive spent fuel rods are stored, would shut off. The most powerful CME in recorded history occurred during a solar cycle with a peak similar to the one scientists are predicting in 2013. Preventing a surge from a CME would be costly. Our backup systems aren’t in place yet, either. NASA comprueba teoría de la relatividad de Einstein - El Universal - Ciencia. Jueves 05 de mayo de 2011Renata Sánchez | El Universal00:59 La misión Gravity Probe B (GP-B) de la agencia espacial estadounidense (NASA) comprobó dos predicciones de la teoría general de la relatividad de Albert Einstein.

Luego de 50 años de haberse concebido el experimento, la nave que costó 760 millones de dólares, demostró que la gravedad se produce cuando la masa curva el espacio y el tiempo, denominado el efecto geodésico, así como el efecto de torsión por arrastre que indica la torsión que se produce en el espacio-tiempo debido a la rotación de los cuerpos. "GP-B determinó ambos efectos con una precisión que no se esperaba al apuntar a la estrella IM Pegasi, mientras orbitaba a la Tierra. Si la gravedad no afectara al espacio y al tiempo, los giroscopios del GP-B se hubieran dirigido a la misma dirección sin importar en que sitio de la órbita se encontrara.

"Imaginen a la Tierra como si estuviera inmersa en miel. ¿Cómo lo logró? El Gravity Probe B cuenta con cuatro giroscopios.

Clash of the Tablets: From iPad to TouchPad, 6 Slates Compared | Gadget Lab. The World’s Longest All-IP Microwave Link « AVIAT NETWORKS: Official Wireless Transmission Blog. Successfully Implementing a 193-km Microwave Link over Water to Deliver 99.9995 Percent Availability Introduction For most designers of microwave transmission paths, engineering a reliable link over water can be a daunting task. Reflections off the water surface can play havoc with the received signal, leading to high levels of interference resulting in fading and ultimately a high level of errors and signal interruptions.

For these types of paths, performance calculations using commercially available software planning tools will be insufficient to ensure superior path performance. Recently, Aviat Networks and our agent, Telecomunicaciones y Sistemas S.A. COCESNA is responsible for the air traffic control over Central America territory and oceanic areas, therefore, availability of service is a critical issue. Key Design Considerations With these parameters in mind, achieving a microwave path that delivers fiber-optic level error performance over water is possible. The Design Figure 1. Introducing EtherCloud. EtherCloud, the re-engineered global Ethernet solution designed and developed by Neutral Tandem and Tinet based on the integration of the company's integrated global network.

EtherCloud is exactly what it sounds like - it's Ethernet and cloud networking all wrapped up in one. For starters, EtherCloud 'connects the islands.' Traditional Ethernet Exchanges provide independent port access to their exchanges, some are even connecting their exchange locations through 3rd party network providers, but none offer one connection that can allow providers access a complete marketplace, regardless of where they are located. Because EtherCloud provides access to any/all of its 100+ network PoPs globally, it also offers a one-stop-shop solution that provides its customers end-to-end delivery all over the world.

By providing the option to deliver end-to-end services, EtherCloud consolidates commercial relationships for its customers. The company is also touting its re-designed customer portal.

Cable Viewer. The “Hispanic Paradox”, and others | Gene Expression. The New York Times has a piece out on the “Hispanic Paradox”. The paradox is that American Hispanics are longer-lived than non-Hispanic whites, despite the relatively lower socioeconomic status of Hispanics (poorer, less educated).

The paradox has been around for a while, and these stories tend to emerge whenever there’s a Census or CDC data release, as there is now. You can get the original data on the CDC website. But I think one thing about the Hispanic Paradox that needs to be contextualized is that Hispanics are not special in manifesting this paradox. More broadly, there are broad swaths of the rural north where whites are relatively poor, but long-lived, in contrast to the South. What is the moral here? Below are some charts from the original CDC report. Note: I’m pretty sure that the Hispanic Paradox does not apply to all Hispanics.

10,000 Visitas. 2011 End User Device Survey -- javascript:void(0) -- InformationWeek. Cloud, mobility, and consumerization are stressing corporate IT. We surveyed 551 business technology pros to see how they plan to shine. Think you can hold the line against the forces pressuring the corporate desktop as we know it? Maybe, if you're in an very security-conscious or heavily regulated company. But the better question is: Should you? The InformationWeek Analytics 2011 End User Device Management Survey of 551 business technology professionals shows that the device landscape has, in some ways, changed tremendously since 2009, when we last surveyed our readership on how they equip their companies' employees.

The Android and tablets are now on everyone's radar, and virtual desktop infrastructure is making gains. But some things have stubbornly remained the same: 51% of us still equip the majority of our users with fat desktops; laptops and smartphones follow in popularity.
