Rats didn’t spread the Black Death

New research has shown that humans, not rats, spread the Black Death in the plague of 1348-1349. Also,

Sloane, who was previously a field archaeologist with the Museum of London, working on many medieval sites, is now attached to English Heritage. He has concluded that the spread of the 1348-49 plague, the worst to hit the capital, was far faster, with an impact far worse than had been estimated previously. While some suggest that half the city’s population of 60,000 died, he believes it could have been as high as two-thirds. Years later, in 1357, merchants were trying to get their tax bill cut on the grounds that a third of all property in the city was lying empty. [emphasis mine]

Space Boat: A Nautical Mission to an Alien Sea

The Titan Mare Explorer: A nautical mission to an alien sea.

If [NASA] green-lights the mission, the capsule will lift off in 2016. By 2023, TiME will be about 800 million miles away in Titan’s north-polar region, home to its biggest lakes and seas. The capsule will take photographs, collect meteorological data, measure depth, and analyze samples. TiME will have no means of propulsion once it is on Titan, so it will float, carried by breezes across the sea’s surface. Then, by the mid-2020s, it will enter a decade-long winter of darkness as the moon’s orbit takes it to the dark side of Saturn, away from the sun and communication. It won’t have a line of sight to Earth to beam back more data until 2035.

American manned space: dependent on the Russians in more ways than you think

American manned space: dependent on the Russians in more ways than you think.

As commentators from around the country gnash their teeth at U.S. dependence upon Russia to move cargo and astronauts to the mostly U.S. built/funded International Space Station (ISS), they’ve missed the bigger boat: With one exception, all the commercial spaceflight offerings currently in the works have Soviet or Russian engines as a key part of the rockets involved.

A blank sun during solar maximum

Though it is not yet official, it appears the sun is blank of sunspots today, for the first time since January 16.

Solar scientists have concluded that the solar minimum of the past four years has ended and that the sun is now moving towards solar maximum. The recent activity in August has seemed to confirm this. However, once the minimum has ended, the sun should not have any further blank days until the maximum is over and the sun is ramping back down to solar minimum. That the sun should appear blank again during its ramp up to solar maximum is quite unusual, probably unprecedented, and is further evidence that the sun is heading towards a period of little or no solar activity.
