Data of the tidal fluxes on Titan by the Cassini spacecraft now suggest that there is a liquid ocean below Titan’s icy crust.

Data of the tidal fluxes on Titan by the Cassini spacecraft now suggest that there is a liquid ocean below Titan’s icy crust.

The teamโ€™s analyses suggest that the surface of the moon can rise and fall by up to 10 metres during each orbit, says Iess. That degree of warpage suggests that Titanโ€™s interior is relatively deformable, the team reports today in Science1. Several models of the moonโ€™s internal structure suggest such flexibility โ€” including a model in which the moon is solid but soft and squishy throughout. But the researchers contend that the most likely model of Titan is one in which an icy shell dozens of kilometres thick floats atop a global ocean. The team’s findings, together with the results of previous studies, hint that Titanโ€™s ocean may lie no more than 100 km below the moonโ€™s surface.

Scientists have found a previously unknown mineral embedded in a meteorite that crashed to Earth in 1969.

Scientists have found a previously unknown mineral embedded in a meteorite that crashed to Earth in 1969.

Dubbed panguite, the new titanium oxide is named after Pan Gu, the giant from ancient Chinese mythology who established the world by separating yin from yang to create the earth and the sky. … “Panguite is an especially exciting discovery since it is not only a new mineral, but also a material previously unknown to science,” says Chi Ma, a senior scientist and director of the Geological and Planetary Sciences division’s Analytical Facility at Caltech and corresponding author on the paper.

Both Russia and the United States have developed a “pain ray” weapon for dispersing protestors.

What could go wrong? Both Russia and the United States have developed a “pain ray gun” for dispersing protestors.

The beam has a much shorter wavelength than a microwave oven and very different effects. The waves penetrate only about 1/64 of an inch, and anyone caught in the beam experiences painful but harmless heating of their skin. It causes what developers call a repel effect; nobody can stand it more than a few seconds before having to get out of the beam.

That’s the American system, not yet used. The Russian system is similar, and the Russians seem ready and willing to put it into operation.

The bloody and corrupt scandal of Obama’s Fast-and-Furious gun-smuggling operation: a summary.

The bloody and corrupt scandal of Obama’s Fast-and-Furious gun-smuggling operation: a summary.

Imagine a government agency designed for the specific purpose of investigating and preventing the unlawful use, manufacture, and possession of firearms. Now imagine this agency engaging in an operation that not only goes against that purpose, but actually seeks to accomplish the opposite, by actively encouraging the sale of firearms to people whose ties to organized crime and gun violence are well known โ€“ and that this operation involves sending firearms across an international border into a country that this agency, and the government of which it is a part, purposely failed to warn, inform, or request permission from.

The scientific stupidity of the TSA’s security rules.

The scientific stupidity of the TSA’s security rules.

Here’s one example from the article:

Take the Transportation Security Administration’s rules about carry-on electronics, for example. Laptops have to come out of their bags and lie flat in a plastic tubโ€”but not tablets, phones, Kindles, cameras or portable game consoles. Why the distinction? The TSA says that it’s not just about detecting explosives: removing bigger gadgets also unclutters your bag for better x-ray examination. Even so, on close inspection the rules get arbitrary very quickly. For example, according to the TSA, the 11-inch model of the MacBook Air is fine to leave in your bag, but the 13-inch model must be removed.

A TSA agent in Florida spilled the cremated remains of a man’s grandfather on the floor after illegally opening the jar to finger the ashes.

A TSA agent in Florida spilled the cremated remains of a man’s grandfather on the floor after illegally opening the jar to finger the ashes.

[John] Gross says about a quarter to a third of the contents spilled on the floor, leaving him frantically trying to gather up as much as he could while anxious passengers waited behind him. “She didn’t apologize. She started laughing. I was on my hands and knees picking up bone fragments. I couldn’t pick up all, everything that was lost. I mean, there was a long line behind me.” [emphasis mine]

Freedom dies, one security checkpoint at a time.
