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.

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.

The Department of Energy has approved the start of detailed engineering for the Large Synoptic Survey Telescope.

Ground-based astronomy moves forward: The Department of Energy has approved the start of detailed engineering for the camera on the Large Synoptic Survey Telescope.

I have to admit, I am puzzled why the Department of Energy is involved in this. Government funding for ground-based telescopes normally comes from the National Science Foundation.

Europe has decided to build a probe, dubbed JUICE, to study Ganymede, Callisto and Europa, Jupiter’s big icy moons.

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.

SEC documents have revealed that the total development costs for Orbital Sciences’ Antares rocket have increased to $472 million, $184 million more than what NASA is paying them.

SEC documents have revealed that the total development costs for Orbital Sciences’ Antares rocket have increased to $472 million, $184 million more than what NASA is paying them.

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.

A microscopic algae-eater that lives in a Norway lake has now been identified as one of the Earth’s oldest living organisms.

A microscopic algae-eater that lives in a Norway lake has now been identified as one of the Earth’s oldest living organisms.

The elusive, single-cell creature evolved about a billion years ago and did not fit in any of the known categories of living organisms – it was not an animal, plant, parasite, fungus or alga, they say.

On Wednesday Obama announced he would overide Congress and release of millions of dollars to the Palestinian Authority, with no strings attached.

What could possibly go wrong? On Wednesday Obama announced he would override Congress and release of millions of dollars to the Palestinian Authority (PA), with no strings attached.

Not only is this insane, considering the murderous behavior of the PA, it seems to me that the U.S. has this document called the Constitution, which clearly stipulations that Congress, not the President, determines how money can be spent. If Congress says no, the President isn’t legally allowed to do it. The article above is vague about this issue, so it is possible that Obama is acting legally here. However, based on his previous behavior, I remain suspicious.

A more detailed analysis of Obama’s action can be found here. It appears my suspicions are correct.

Congress deliberately froze those funds, and not just because of the statehood demand through UNESCO. Hamas, a terrorist organization, reconciled with Fatah and has rejoined the PA, which means we’re putting almost $200 million into the hands of a terrorist organization. The language of the Palestinian Accountability Act could not be clearer: “[N]o funds available to any United States Government department or agency … may be obligated or expended with respect to providing funds to the Palestinian Authority.” Obama literally waived that statutory language off yesterday afternoon. [emphasis mine]

For this President, a supposed Constitutional lawyer, the law is always such an inconvenient thing. He somehow thinks that, under our legal system, he can rule by dictate, something that any legal scholar would tell him is wrong.

The faster we get this power-hungry man out of office, the better.

In closing down its ATV cargo freighter assembly line, Europe considers its next manned space project.

In closing down its ATV cargo freighter assembly line, Europe considers its next manned space project.

ESA and NASA have been discussing how ESA might compensate NASA for Europe’s 8.3 percent share of the international space station’s future operating charges. Until about 2017, the agency is repaying NASA, as the station’s general contractor, through launches of European Automated Transfer Vehicle (ATV) cargo ships to the station. But with the station partners now all but committed to operating the station at least through 2020, ESA is searching for another “barter element” to succeed ATV.

NASA has said a propulsion module for the Orion Multi-Purpose Crew Vehicle would fill ESA’s obligations to NASA, which have been estimated at about 450 million euros ($600 million) over three years.

But several ESA members, notably France and Italy, have argued that the Orion module, which would use ATV-derived technologies, does not provide sufficient technology interest or public impact. Instead, these governments have proposed development of a vehicle that would perform multiple tasks in low Earth orbit, including debris removal.

The Labor Department has abandoned its effort to ban kids from working on farms.

A victory of sorts for freedom: The Labor Department has abandoned its effort to ban kids from working on farms.

The reason I consider this merely a temporary victory is that the desire to regulate these matters still exists in the people running the federal government. These same people also don’t understand that, as a free nation, they have no moral right to impose these rules in the first place. Thus, they remain a threat, waiting only for another opportunity to try again.
