Traffic and more roads
Puncturing the myth that more roads mean more congestion Key quote:
Read enough of these studies and you get a sense that much of the induced-demand hubbub is really a sub rosa extension of the war on the suburbs: Stop highway expansion and you can make life miserable enough for the minivan-driving masses that they’ll move out of their gauche “urban-fringe developments” and back to high-density metropolitan cores, where they belong.
In reading the full essay, I was struck by how much the scientific campaign against road construction reminded me of climategate.

Northern Lights
An evening pause: When the Sun gets active, such as the solar flare of February 15, 2011, the sky in the high latitudes gives us the world’s best light show.
The caves of Copernicus
and the Ocean of Storms
The discovery of new caves on the Moon keep coming. Today I have two new stories. The first is a discovery by professional scientists of a giant lava tube cave in the Oceanus Procellarum or Ocean of Storms. The second is the detection of a plethora of caves and sinks on the floor of the crater Copernicus, found by a NASA engineer who likes to explore the gobs of data being accumulated by Lunar Reconnaissance Orbiter and made available to all on the web.
The image below of the Moon’s near side, taken by India’s Cartosat-2A satellite and taken from the science paper, shows the location of lava tube in Oceanus Procellarum (indicated by the red dot) and the crater Copernicus.
First the professional discovery. Yesterday, the Times of India reported the discovery of lava tube more than a mile long on the Moon. I did not post a link to the article because I didn’t think the news story provided enough information to make it worth passing along. Today however, fellow caver Mark Minton emailed me the link where the actual research paper could be downloaded [pdf]. This I find definitely worth describing.

Two High-priority Climate Missions Dropped from NASA’s Budget Plans
Two high-priority climate missions dropped from NASA’s budget by the White House. And what’s most amazing: No one’s squealing!
“Removal of these missions was not what we desired and not what the administration desired, but it was a clear recognition and acknowledgement of the budget issues we face as a nation,” [said Steve Volz, associate director for flight programs at NASA’s Earth Science Division]. “It’s cleaner to be allowed to delete the scope that goes along with the dollars than to have to figure out how to do more with less.”

Detector Array Deterioration Poses New Problem for JWST
More problems for the James Webb Space Telescope: The detector arrays for several instruments are deteriorating, even as they sit on the shelf. And remember, the 2014 launch date is probably going to be delayed until 2016. Key quote:
“As you get further and further out with [the launch date], it really raises questions about how far down the [integration and test] process you go for the instruments … and how long you have to store all that before you actually launch,” [Webb program director Rick Howard] told the NASA Advisory Council’s astrophysics subcommittee during a Feb. 16 public meeting here. “And that just makes everybody even more nervous about this problem than anything else.”

Another climategate whitewash
The inspector general of the Department of Commerce has just issued a review of NOAA’s response to the climategate emails and has essentially given the agency a clean bill of health. You can download the full report here [pdf].
It’s. just. another. whitewash. Let me quote just one part of the report’s summary, referring to a Freedom of Information Act (FOIA) request to NOAA in June 2007 in which the agency responded by saying they had no such documents:

Researchers have uncovered the oldest cremated human remains ever discovered in northern North America at a site in central Alaska
Scientists have uncovered the oldest cremated human remains ever discovered in northern North America at a dig site in central Alaska. Key quote:
Archaeologists discovered the remains last spring in a fire pit in an abandoned living area from 13,200 years ago and dated the child’s death to about 11,500 years ago.

The squealing of a former Bush science administrator
The cries and squeals are now coming from all sides: A former undersecretary for Science in the Energy Department during the Bush administration, Raymond L. Orbach, has joined the chorus of scientists whining about the House’s proposed cuts. [His full editorial, available here as a pdf, can only be downloaded if you subscribe to Science.]
Like all the other squealers, he admits that “the budget deficit is serious.” Nonetheless, the idea of cutting his pet science programs remains unacceptable.
It is when I read stuff like this that feel the situation is most hopeless. Is there no one willing to accept the reality that if we don’t start gaining some control over the federal budget the country will go bankrupt and we will not be able to afford anything?
Instead, all I hear are cries of “Cut! Cut! But don’t cut my program!”

Scientists Steer Car With the Power of Thought
What could go wrong? Scientists have developed technology allowing someone to steer a car by thought alone. Key quote:
“In our test runs, a driver equipped with EEG sensors was able to control the car with no problem — there was only a slight delay between the envisaged commands and the response of the car,” said Prof. Raúl Rojas, who heads the AutoNOMOS project at Freie Universität Berlin.

Does dark energy and dark matter exist, or is it our theories of gravity?
The uncertainty of science: New evidence suggests that rather than postulate the existence of dark energy and dark matter, scientists need simply to revise their theories of gravity.

The high priests of science and how they bar the door to skeptics
The high priests of science and how they bar the door to skeptics. A paper is published in Nature claiming that Antarctica is warming as predicted by global warming advocates.
The indefatigable Steve McIntyre started to scrutinize [this paper] along with Nicholas Lewis. They found several flaws: Steig et al had used too few data sequences to speak for an entire continent, and had processed the data in a very questionable way. But when they wanted to correct him, in another journal, they quickly ran into an inconvenient truth about global warming: the high priests do not like refutation. To have their critique (initial submission here [pdf], final version here [pdf]) of Steig’s work published, they needed to assuage the many demands of an anonymous ‘Reviewer A’ – whom they later found out to be Steig himself. [emphasis mine]
It is unconscionable for any science journal to have allowed Steig, the author of the paper under attack, to act one of the anonymous reviewers. But hey, what do I know? I’m only a simple science writer.

The Massive February 15, 2011 X Flare on the Sun
An evening pause: On February 15, 2011, the Sun emitted its strongest flare in four years. Though the Sun continues to act relatively wimpy as it ramps up towards solar maximum, this flare was spectacular, mostly because we now have some amazing instruments in space to image and study it. This video does an excellent job explaining what was happening, as it happened. Watch, and enjoy.
And note, as powerful as this flare was, and despite the fact that it was pointed right at the Earth, it represented a relatively minor threat to our technological society, despite what some doomsayers might be claiming. A very active Sun can cause us problems, especially with power systems and electrical grids, but based on past experience during previous solar maximums, most power companies have taken careful steps to protect themselves from this risk. And with the Sun as weakly active as it is, the risks are further reduced. The doomsayers are simply shilling for more government research dollars.
