Though HH 46/47 has been studied for about 10 years, new imaging techniques have allowed scientists to see it even more clearly now. The green in this picture shows hydrogen gas molecules and dust, while the blue represents gas energized by those supersonic jets. The red colors show the fast expansion of carbon monoxide gas. JPL

Burns is a prodigious inventor and a staunch supporter of clean energy, but he’s no sentimental environmentalist. He’s an oilman. He made his first fortune in the mid-1970s with oil and gas discoveries off Australia’s northwestern coast. In 1987 he founded the exploration company Hardman Resources, which, after an extremely profitable series of finds off the coast of Africa, was sold in 2006 to another oil company for more than $1 billion....

A lot of the actions proposed in these plans are familiar: scaling up wind and solar power, building more public transit, and restoring natural landscapes to store carbon in trees, plants, and soil. But then there’s talk about “carbon capture and storage,” or CCS, an amorphous, futuristic-sounding technology. Some climate experts think it’s basically impossible to meet goals like keeping warming below 1.5ºC without this tool. But what exactly is it?...

But activity conducted through Tor isn’t entirely untraceable, and there’s increasing evidence that, in exchange for cash, a security research team at Carnegie Mellon turned over information to legal authorities that led to several arrests. Tor lets people use the internet anonymously by routing data through some of the many nodes in a complex network, obscuring the start point and end point. Built from an idea in the mid-1990s to let government officials securely communicate on civilian internet networks without revealing their location, Tor was one of many tools used by activists during the Arab Spring protests of 2011 to communicate while avoiding government scrutiny....

However, a study published today in the journal Pediatrics finds that while too much screen time can slow children and adolescent recovery from concussions, completely banning screen time might not be the answer. The researchers from the University of British Columbia (UBC) and the University of Calgary in Canada looked at more than 700 children between eight and 16 year-old in the first seven to 10 days after an injury and their screen time and the symptoms over the following six months....

The project began when another local artist asked de Gouveia if he wanted to create a sculpture for the 2011 Chico Wildflower Century Ride. De Gouveia decided to build an unofficial clock for the bike event. He called on nearby cycling communities to donate used bikes, and once enough junkers rolled into his shop, he held a “disassembly party” to remove their gears, frames, chains, and other components. De Gouveia pieced together the gigantic clock’s skeleton from the scrap metal in roughly three weeks, and then spent another three weeks adding parts and tuning the gears....

A recent demonstration by Alan Willner, an engineer at the University of Southern California, moved 100 terabits (the equivalent of 2,600 DVDs) per second through the air—the fastest data transfer in free space ever. But before the tech will work commercially, engineers need to finish developing a new cable that can carry the light.

“Satellite 1970 PL-2 is evidently a surveillance satellite. Nuclear radiation from it indicates a power reactor, not a warhead.” The decoded message may be phrased in English, Russian, or still another language. It would indicate that the alien satellite was no orbital nuclear bomb—and that there was not yet a “hot” space war. Interception and examination of suspicion satellites by manned spacecraft may be foreseen in the near future. It will be one of the logical developments of the cold war in space—a strange, secrecy shrouded contest, short of open hostilities but with deadly serious military implications—that is going on right now....
