Electric car company shuts down

11:25 pm

For once, the taxpayer doesn’t get screwed: The electric car company Aptera has shut down due to lack of interest from investors and the lack of a loan from the government.

The California company was counting on a federal loan – and private investments to match the loan – so that it could start producing its very first electric vehicle. Aptera said it was close to securing a $150 million from the U.S. Department of Energy, but it couldn’t line up the private dollars necessary to complete the loan application process.

Nature: Political science in Durbin

11:17 pm

The headline (from Nature) proves how little the Durban climate conference has to do with science: Bridging the gap: Political science in Durban.

This conference, as well as all past UN climate conferences, has always been about politics and money, not science. And the last line of the article even emphasizes the point:

More on all of that next week as negotiators work to avert disaster and identify a politically palatable path forward — and some money to make it all happen. [emphasis mine]

A crab that grows its own food

A crab that grows its own food.

In the deep ocean off the coast of Costa Rica, scientists have found a species of crab that cultivates gardens of bacteria on its claws, then eats them. The yeti crab — so-called because of the hair-like bristles that cover its arms — is only the second of its family to be discovered. The first — an even hairier species called Kiwa hirsuta — was found in 2005 near Easter Island.

Mountains and buried ice on Mars

Mountains and buried ice on Mars.

New images from the high-resolution stereo camera on ESA’s Mars Express orbiter allow a closer inspection [of the Phlegra Montes mountain range] and show that almost every mountain is surrounded by ‘lobate debris aprons’ – curved features typically observed around plateaus and mountains at these latitudes. Previous studies have shown that this material appears to have moved down the mountain slopes over time, and looks similar to the debris found covering glaciers here on Earth.

More budget battles in Europe over $16 billion fusion reactor project

4:58 pm

The budget battles continue in Europe over funding a $16 billion fusion reactor project.

Now the three statutory bodies of the European Union have agreed to cobble together €360 million from anticipated unspent funds in the still-to-be-decided 2013 budget. Another €840 million will be found by shifting money from 2012 and 2013 budget lines for farm and fishing subsidies, rural development, and environment, into the ones covering research. The remaining €100 million had already been allocated to ITER in the 2012 budget.

Sounds to me as if this whole thing has feet of clay, and is going to fall apart long before completion.

Diederik Stapel, the Dutch social psychologist who admitted to faking data in numerous published papers, has retracted his first paper

12:29 pm

Diederik Stapel, the Dutch social psychologist who admitted to faking data in numerous published papers, has retracted the first paper of many, with more retractions sure to follow.

A day earlier, the Dutch university committees investigating Stapel issued a preliminary report that indicated that Stapel had fabricated or manipulated data in at least several dozen publications, but the report did not name specific papers (see Report finds massive fraud at Dutch universities).

The committees, at the universities of Amsterdam, Groningen and Tilburg where Stapel studied and worked between 1994 and 2011, plan to identify tainted papers in a final report that will not be completed until mid-2012 at the earliest, says Pim Levelt, head of the Tilburg committee and director emeritus at the Max Planck Institute for Psycholinguistics in Nijmegen, Netherlands.

Why can’t the climate field do this? It would help them recover the trust they have lost resulting from the obvious research frauds uncovered by the climategate emails.

Over-the-counter osteoporosis drug appears to keep astronauts from losing bone density on long space flights

10:14 am

Big news: New research on ISS now shows that the standard over-the-counter osteoporosis drugs used by millions on Earth appears to keep astronauts from losing bone density during long space flights.

Beginning in 2009, the group administered the drug to five long-stay astronauts on the International Space Station (ISS), including Koichi Wakata, 48, and Soichi Noguchi, 46. The five took the drug — an over-the-counter bisphosphonate used to treat osteoporosis — once a week starting three weeks before they lifted off until they returned to Earth. The researchers then monitored the astronauts’ bone mass over time and compared the results to those for 14 astronauts that had never taken the drug.

The results showed that the 14 who had never taken the drug had average bone density loss of 7 percent in the femur, and 5 percent in the hip bone. The five astronauts on bisphosphonate, however, only had average bone density loss in the femur of 1 percent, and even a 3 percent increase in the hip bone. Calcium levels in their urine, which rise the more bone mass is lost, were also very low.

If these results hold up, they might very well solve one of the biggest challenges faced by any interplanetary traveler. Up until now, bone loss during long weightless missions never seemed to average less than 0.5 percent per month. After spending three years going to and from Mars, an astronaut could thus lose about almost 20 percent of their bone mass in their weight-bearing bones, and would probably be unable to return to Earth.

Thus, a mission to Mars seemed impossible, unless we could build a ship with some form of artificial gravity, an engineering challenge we don’t yet have the capability to achieve.

If these already tested drugs can eliminate this problem, then the solar system is finally open to us all. All that has to happen now is to do some one to two year manned missions on ISS to test the drugs effectiveness for these long periods of weightlessness.

NASA confiscates stolen rocket engine that had been put up for sale on ebay

5:13 pm

NASA has confiscated a stolen rocket engine from a man who put up for sale on ebay.

Rocket engines are supposed to be under particularly tight control at NASA: the US is keen to avoid its rocket technology winding up in the hands of countries with which it has a tense relationship, such as China. “Security at NASA is not adequate in my opinion,” says Joseph Gutheinz, a former investigator for OIG.

You think, eh?

The first observations of a star, just prior to going supernova

1:30 pm

Astronomers have for the first time observed the changes that took place in a binary star system in the years before one star in the system erupted as a supernova.

In the first survey of its kind, the researchers have been scanning 25 nearby galaxies for stars that brighten and dim in unusual ways, in order to catch a few that are about to meet their end. In the three years since the study began, this particular unnamed binary system in the Whirlpool Galaxy was the first among the stars they’ve cataloged to produce a supernova.

The astronomers were trying to find out if there are patterns of brightening or dimming that herald the end of a star’s life. Instead, they saw one star in this binary system dim noticeably before the other one exploded in a supernova during the summer of 2011.

Key quote: “Our underlying goal is to look for any kind of signature behavior that will enable us to identify stars before they explode,”

The supernova in question, 2011dh, was the closest supernova in decades, occurring in June 2011 in the Whirlpool Galaxy (M51). See my previous posts here and here.
