The CERN physicist who planned bombing attacks with Islamic terrorists has been sentenced to five years in prison.
The sentence includes one year “suspended”, and might end up being shortened further for time served and other sentence reductions. I wonder what he’ll do when he gets out.

The five men arrested for planning to blow up a bridge in Ohio turn out to all be active Occupy Wall Street activists.
Why am I not surprised? The five men arrested for planning to blow up a bridge in Ohio turn out to all be active Occupy Wall Street activists.
As despicable as this act of violence might have been, it is just as despicable for major news organizations to fail to mention the important fact that they are Occupiers.

A new study has found that the glaciers of Greenland are not behaving as predicted.
The uncertainty of science: A new study has found that the glaciers of Greenland are not behaving as predicted.
In northwestern Greenland, for example, where most of the glaciers move relatively quickly and flow directly into the sea rather than ending on land, average speed jumped by 8% between 2000 and 2005 and rose another 18% from 2005 to 2010. Nevertheless, the researchers report online today in Science, the glaciers in this region showed no uniform pattern of acceleration. About one-third flowed at the same rate throughout the decade, one-fourth slowed during the interval, and about 15% slowed during the first half of the decade and then surged from 2005 to 2010.
Similarly, many of the individual glaciers in southeastern Greenland don’t follow the region’s overall trend. Although the average speeds for these glaciers increased by 28% over the decade, substantial accelerations by some glaciers were balanced by considerable slowing by others. About 43% of the glaciers in the region sped up between 2000 and 2005, but around 25% slowed down by more than 15% from 2005 to 2010.
In other words, if there is any warming, it hasn’t manifested itself in a predictable manner in the glaciers of Greenland. In fact, the data above suggests instead that if there has been any warming, it either has been far less than predicted, or has had relatively little influence on the Greenland ice sheet.

Scientists have discovered that the half life of one of their key isotopes for dating the solar system is 30% shorter than previously believed.
The uncertainty of science: Scientists have discovered that the half life of one of their key isotopes for dating the age of the solar system is 30% shorter than previously believed.
The main result of the work of the international scientists, detailed in a recent article in Science, is a new determination of the half-life of 146Sm, previously adopted as 103 million years, to a much shorter value of 68 million years. The shorter half-life value, like a clock ticking faster, has the effect of shrinking the assessed chronology of events in the early solar system and in planetary differentiation into a shorter time span.
The new time scale, interestingly, is now consistent with a recent and precise dating made on a lunar rock and is in better agreement with the dating obtained with other chronometers. The measurement of the half-life of 146Sm, performed over several years by the collaborators, involved the use of the ATLAS particle accelerator at Argonne National Laboratory in Illinois.

A special issue from Nature: Peopling the planet.
I haven’t yet had time to read this special issue, but it will certainly be fascinating, as it apparently summarizes the most current knowledge scientists have about the manner and timing of the human migration of the entire surface of the Earth. Overall, it appears that this migration took place sooner and faster than previously believed. Definitely worth a read.

Europe has decided to build a probe to study Ganymede, Callisto and Europa, Jupiter’s big icy moons.
Known as JUICE, the Jupiter Icy Moons Explorer, the probe will enter orbit around the gas giant planet in 2030 for a series of flybys of Ganymede, Callisto and Europa. JUICE will brake into orbit around Ganymede, Jupiter’s largest moon, in 2032 for at least one year of close-up research.

An Australian billionaire is building a full scale replica of the Titanic.
Want to relive history? An Australian billionaire is building a full scale replica of the Titanic.
When fully built, the Titanic II will be 270 meters (886 feet) long and capable of holding 1,680 passengers. By modern standards, this is actually fairly small for a cruise ship, especially when compared to newer passenger liners like the behemoth Oasis of the Seas, which measures 360 meters (1,180 feet) long and can hold 5,400 guests.
The Titanic II is set to make the same maiden voyage as the original, traveling from England to New York, by late 2016.

That the company has been willing to commit these extra funds to develop Antares suggests to me that they see a commercial value for the rocket that will exceed these costs. Or to put it more bluntly, they see a market for their rocket that will pay for their investment, and then some.
