Children should be limited to less than two hours of entertainment-based screen time per day, and shouldn’t have TVs or Internet access in their bedrooms, according to new guidelines from pediatricians.
The Omega Center for Sustainable Living may be the most beautiful wastewater treatment plant in the world. It is powered by solar and geothermal power, so it requires no additional power to operate. Unlike other wastewater treatment plants, the OCSL does not use chemicals to treat the water, but rather mimics the processes of the nature world, such as using a combination of microorganisms, algae, plants and gravel and sand filtration to clean sewage water and return clean drinkable water back to the aquifer.
In addition to doing all of this, the OCSL also functions as a classroom, to help educate and inspire people about the power of nature to provide solutions…
Since the 1850s, engineers have been experimenting with powered lighter-than-air flight, essentially balloons with steering and propulsion. Like other early aeronautical experiments, the trial-and-error period was lengthy and hazardous. Dirigibles (with internal support structures) and blimps (powered balloons) were filled with lifting gases like hydrogen or helium, intended for many uses, from military and research to long-distance passenger service.
The growth of the airship suffered numerous setbacks, including the famous Hindenburg disaster in 1937, and never developed into a major mode of travel. Despite the challenges, more than 150 years later, a number of airships are still in use and development around the world as cargo carriers, military platforms, promotional vehicles, and more.

Next Mars rover will assess the Red Planet for human habitability!
NASA’s next Mars-exploring robot, slated for launch in 2020, will evaluate the planet’s ability to support human life, as well as collect samples that it may one day bring back to Earth! NASA researchers are actually taking submissions for experiments and instruments to load on-board the future craft, so send in your ideas!

Van Allen’s Probe marks First Anniversary With New Discoveries and New Investigations
by Geoff Brown - JHU/APL
One year after their launch from Cape Canaveral Air Force Station at 4:05 a.m. E DT on Thursday, Aug. 30, 2012, NASA’s twin Van Allen Probes have already fundamentally changed how we understand the Van Allen radiation belts above our planet.
Data from the probes have already led to several significant discoveries, some made just days after the special twin spacecraft soared into orbit. The mission has answered one long-standing question about the nature and behavior of the belts, and revealed that the outer belt can split into two separate belts. With this first year of discovery and enhancements in operations as a cornerstone, the science teams of the Van Allen Probes (formerly named the Radiation Belt Storm Probes) are looking forward to unlocking further mysteries and advancing our knowledge of particle physics and the dynamics of space plasmas, as well as how to better protect space-based technologies like satellites…
Astronomers have built a new astro-camera that, when fitted onto the largest observatories on Earth, can snap photos of the universe twice as sharp as the famed Hubble Space Telescope.
With the newly developed technology, giant telescopes can reach their theoretical limits of resolution in visible light —something that was just not possible, until now, because of atmospheric turbulence causing blurry visible light images.
Called Adaptive Secondary Mirror (ASM), this new imaging technology sits high above the primary mirror of the telescope, working to counter the atmospheric turbulence by changing the shape of its thin curved glass mirror 1,000 times each second…
NASA’s Spitzer Space Telescope Celebrates 10 Years
Ten years after a Delta II rocket launched NASA’s Spitzer Space Telescope, lighting up the night sky over Cape Canaveral, Fla., the fourth of the agency’s four Great Observatories continues to illuminate the dark side of the cosmos with its infrared eyes.
The telescope studied comets and asteroids, counted stars, scrutinized planets and galaxies, and discovered soccer-ball-shaped carbon spheres in space called buckyballs. Moving into its second decade of scientific scouting from an Earth-trailing orbit, Spitzer continues to explore the cosmos near and far. One additional task is helping NASA observe potential candidates for a developing mission to capture, redirect and explore a near-Earth asteroid…
NOAA’s GOES-12 satellite was decommissioned on August 16th, 2013 after 3,788 days in service. From April 2003 — May 2010, GOES-12 served as GOES East, providing “eye in the sky” monitoring for such memorable events as the 2005 Atlantic hurricane season and the series of blizzards during the winter of 2009-2010. After suffering thruster control issues, GOES-12 was taken out of normal service and moved to provide greater coverage of the Southern Hemisphere as the first-ever GOES South. During that time it provided enhanced severe weather monitoring for South America.
This animation shows one image from each day of the satellite’s life — a total of 3,641 full disk visible images.
RoboSimian, an ape-like disaster-recovery robot designed and built at NASA’s Jet Propulsion Laboratory, Pasadena, Calif., has passed a critical design review. The Defense Advanced Research Projects Agency (DARPA) selected RoboSimian to advance in competition to the agency’s Robotics Trials to be held at the Homestead-Miami Speedway in Florida in December.
A full list of teams progressing to the DARPA Robotics Trials is online at: here .

NASA’s Voyager 1 spacecraft, launched more than 35 years ago and now 11.5 billion miles from where it started, is closing in on this boundary. In recent years scientists have been waiting eagerly for it to become the first artificial object to leave the solar system and enter the wider reaches of the Milky Way, which they fully expect it to do. But there has been at least one false alarm…
