¿Quiénes hacen funcionar Internet?

El ecosistema de Internet está compuesto por todas aquellas organizaciones y comunidades que colaboran con el funcionamiento y la evolución de la red.

Entre las organizaciones que conforman el Ecosistema de Internet se incluyen:

Comunidad técnica: técnicos, ingenieros, arquitectos, creativos, organizaciones como el IETF y el Consorcio World Wide Web (W3C) que ayudan a coordinar e implementar estándares abiertos.
Organizaciones que gestionan recursos para asignar direcciones globales:ICANN, RIR y otros.
Operadores, ingenieros y proveedores que ofrecen servicios de infraestructura de red: proveedores de servicio de nombres de dominio (DNS), operadores de redes y puntos de intercambio de tráfico en Internet (IXP).
Usuarios de Internet que utilizan Internet para comunicarse entre sí y ofrecer servicios.
Educadores que ofrecen formación y crean capacidad para desarrollar y utilizar tecnologías de Internet.
Políticos encargados de tomar decisiones que promueven el desarrollo de políticas locales y globales.

Lava Sampling — USGS geologists at the Hawaiian Volcano Observatory (HVO) still get fresh lava samples as close to the vent as possible. Once the sample is scooped from the pāhoehoe lobe, it is quickly quenched in a bucket of water to stop the growth of any crystals and to preserve the composition of the liquid lava. Once cooled, the sample is sent first to UH Hilo for quick analysis of a few components and prepared for a fuller analysis of its chemical components by a lab on the mainland. These data are used, with HVO's geophysical monitoring data, as another way to assess any changes that may be occurring within Kīlauea volcano.

Learn more about the science happening at HVO along with photos, maps, and video clips at http://on.doi.gov/HVOPhotoUpdates

Changes in permafrost landscapes

Earth's cryosphere is particularly susceptible to climate change. Rising temperatures are certain to result in profound and widespread changes at high latitudes, where the ground remains frozen all year. Approximately one quarter of the Northern Hemisphere contains permafrost – an area so vast it can only be regularly and comprehensively monitored through satellite remote sensing. The Lena Delta in Siberia lies in such a permafrost zone; it consists of a number of islands and river channels that are covered by ice in winter. A part of this river delta was imaged by the DLR TanDEM-X satellites in October 2014.

Revitalized 0.81m telescope studying properties of NEOs

http://planet.ly/Df1n4

Thanks to a new focal reducer and re-aluminized mirror from a Shoemaker NEO grant, a 0.81-meter telescope in Italy is performing astrometric follow-up observations and physical studies of asteroids.

As Stars Form, Magnetic Fields Influence Regions Big and Small: Stars form when gravity pulls together material within giant clouds of gas and dust. But gravity isn't the only force at work. Both turbulence and magnetic fields battle gravity, either by stirring things up or by channeling and restricting gas flows, respectively. New research focusing on magnetic fields shows that they influence star formation on a variety of scales, from hundreds of light-years down to a fraction of a light-year.
