3D Printed House

This is a game changer for affordable housing. The house pictured below was tested on-site in 24 houses at a cost of $10,000.



An Entire Home Was 3-D Printed in Just 24 Hours – RealClearLife
A 400 square foot home in Stupino, Russia, a small town near Moscow, was 3D printed in 24 hours. Apis Cor 3D printed the house using a mobile printer.

The Center Must Hold

Excellent article by Tony Blair. I believe the center will hold; it has to, the alternative is too frightening.



Tony Blair: Against Populism, the Center Must Hold – The New York Times
The forces of technology and global trade have broken up traditional left-right politics. Progressives need to build a new coalition.

The events surrounding the Big Bang were so cataclysmic that they left an indelible imprint on the fabric of the cosmos. We can detect these scars today by observing the oldest light in the Universe. As it was created nearly 14 billion years ago, this light —which exists now as weak microwave radiation and is thus named the cosmic microwave background (CMB)—has now expanded to permeate the entire cosmos, filling it with detectable photons.

The CMB can be used to probe the cosmos via something known as the Sunyaev-Zel’dovich (SZ) effect, which was first observed over 30 years ago. We detect the CMB here on Earth when its constituent microwave photons travel to us through space. On their journey to us, they can pass through galaxy clusters that contain high-energy electrons. These electrons give the photons a tiny boost of energy. Detecting these boosted photons through our telescopes is challenging but important— they can help astronomers to understand some of the fundamental properties of the Universe, such as the location and distribution of dense galaxy clusters.

The NASA/ESA Hubble Space Telescope observed one of most massive known galaxy clusters, RX J1347.5–1145, seen in this Picture of the Week, as part of the Cluster Lensing And Supernova survey with Hubble (CLASH). This observation of the cluster, 5 billion light-years from Earth, helped the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile to study the cosmic microwave background using the thermal Sunyaev-Zel’dovich effect. The observations made with ALMA are visible as the blue-purple hues.

Seven Earth-sized Planets Discovered

NASA's Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water.
