SpaceX Wins FAA Permission To Build a Spaceport In Texas 80

Jason Koebler writes SpaceX just got approval from the Federal Aviation Administration to build a 56.5-acre spaceport along the Gulf of Mexico on the Texas-Mexico border—a huge step toward actually making the spaceport a reality. Wednesday, the FAA, which handles all commercial space launch permitting in the United States, issued what's known as a "Record of Decision" that suggests the agency would allow the company to launch 10 Falcon 9 rockets and two Falcon Heavy rockets per year out of the spaceport, through at least 2025.

Hints of Life's Start Found In a Giant Virus 158

An anonymous reader points out this update on the world's largest virus, discovered in March. Chantal Abergel and Jean-Michel Claverie were used to finding strange viruses. The married virologists at Aix-Marseille University had made a career of it. But pithovirus, which they discovered in 2013 in a sample of Siberian dirt that had been frozen for more than 30,000 years, was more bizarre than the pair had ever imagined a virus could be. In the world of microbes, viruses are small — notoriously small. Pithovirus is not. The largest virus ever discovered, pithovirus is more massive than even some bacteria. Most viruses copy themselves by hijacking their host's molecular machinery. But pithovirus is much more independent, possessing some replication machinery of its own. Pithovirus's relatively large number of genes also differentiated it from other viruses, which are often genetically simple — the smallest have a mere four genes. Pithovirus has around 500 genes, and some are used for complex tasks such as making proteins and repairing and replicating DNA. "It was so different from what we were taught about viruses," Abergel said. The stunning find, first revealed in March, isn't just expanding scientists' notions of what a virus can be. It is reframing the debate over the origins of life."

The Oatmeal Convinces Elon Musk To Donate $1 Million To Tesla Museum 78

Ars Technica notes (as does Oatmeal creator Matthew Inman) that Elon Musk has agreed to donate $1 million towards the restoration of Nikola Tesla's old lab as a museum, a project that Inman has been pushing for some time now. And if you happen to get there in a Tesla, you're in luck: Musk is also planning to install one of his company's superchargers in the parking lot. (At the other end of the east coast, you can visit a very different kind of Tesla museum.)

Mathematicians Solve the Topological Mystery Behind the "Brazuca" Soccer Ball 144

KentuckyFC (1144503) writes "In the 1970 World Cup in Mexico, teams used a new kind of ball called the Telstar made from 12 black pentagonal panels and 20 white hexagonal panels. This ball has icosahedral symmetry and its own molecular analogue in the form of C60, the famous soccer ball-shaped fullerene. In 2006, a new ball called the TeamGeist was introduced at the World Cup in Germany. This was made of 14 curved panels that together gave it tetrahedral symmetry. This also had a molecular analogue with tetrahedral symmetry among the fullerenes. Now teams at the current World Cup in Brazil are playing with yet another design: the Brazuca, a ball constructed from six panels each with a four-leaf clover shape that knit together like a jigsaw to form a sphere. This has octahedral symmetry. But here's question that has been puzzling chemists, topologists and..errr...soccer fans: is there a molecular analogue of the Brazuca? Or put another way, can fullerenes have octahedral symmetry? Now a pair of mathematicians have finally solved this problem. They've shown that fullerenes can indeed have octahedral symmetry just like the Brazuca, although in addition to hexagonal and pentagonal carbon rings, the ball-shaped molecules must also have rings of 4 and 8 carbon atoms. The next stage is to actually synthesis one of these fullerenes, perhaps something to keep chemists occupied until the 2018 World Cup in Russia."
