drorzel | April 29, 2008Via Swans on Tea, a new article on the arxiv reports the possible discovery of a new stable element:
What they did was fire one thorium nucleus after another through a mass spectrometer to see how heavy each was. Thorium has an atomic number of 90 and occurs mainly in two isotopes with atomic weights of 230 and 232. All these showed up in the measurements along with a various molecular oxides and hydrides that form for technical reasons.
But something else showed up too. An element with a weight of 292 and an atomic number of around 122. That's an extraordinary claim and quite rightly the…
pontiff | April 28, 2008After a comment suggesting that a Science Film festival be held to combat a certain idiotic movie, He of Uncertain Principles agreed, and then the powers that be at scienceblogs decided to hold a poll on the Best Science Movies. And the four choices are...."Contact", "Gattaca", "An Inconvenient Truth", and "Jurassic Park." To which I can only say...
What! No "Real Genius?" I mean come on! Talk about the ultimate of geeky science movies. Make that geeky physics science movies. Do I even need to count the ways? Okay I guess I do:
Lasers. Really, really powerful lasers. Lasers so…

This amusing streaming video is a rockin' version of Richard Dawkins' expertise [3:57].
drorzel | April 27, 2008Over at Shifting Baselines, Randy Olson posts a comment suggesting how to combat anti-science movies like Expelled:
You want to know how to start -- why doesn't somebody run a film festival for pro-evolution films? THAT is how you reach out to tap into new voices, new blood, new perspectives. THAT is what is desperately needed. Efforts to fan the fires of creativity and innovation. THAT was how I got started as a filmmaker -- winning awards at the New England Film and Video Festival while I was still a professor. That festival, and others, drew me into the world of filmmaking. But right now,…
drorzel | April 26, 2008I went for a bike ride this morning, the first real bike ride of the year (I've biked to and from work a couple of times, but this was the first real ride just for the sake of riding). There was some pissy drizzle at the start, but by the time I got on the bike path headed for Lock 8, the sun came out, and it was a cool, pleasant, calm spring morning.
As I was tooling down the path, I realized that I had the bike one gear higher than I usually do on that stretch of path, but I didn't feel like I was working any harder than normal. "Gee, I guess I'm in better shape than I thought..." I said to…

Happy DNA Day!
It's been slow here on the blog lately, for a number of reasons - the most salient of which is that I've been on the Hill all week at the Congressional Operations Seminar sponsored by the Government Affairs Institute at Georgetown. I highly recommend this course - it was a lot of fun. But unfortunately I didn't have a functional laptop this week, and thus couldn't blog. (At one point, my poor Mac burped up a blue screen of death - I didn't even know such a thing was possible!)
Yesterday, I just missed…

A friend, Dave, sent me an interesting article that was published several months ago in Science. This insightful and well-written article by Jennifer Couzin is important because it focuses on one scientist's trauma and ensuing lifelong journey with rejecting his evangelical creationist upbringing to accept evolution as scientific fact. Below the fold is a summary of this article for you to read.
Paleontologist Stephen Godfrey, curator of the Calvert Marine Museum in Solomons, Maryland, started out his life incongruously as…
drorzel | April 25, 2008The organizers of the Science in the 21st Century conference at the Perimeter Institute have started to collect talk abstracts for the meeting. Actually, they started a couple of weeks ago, but I'm a Bad Person and haven't gotten around to writing anything for them yet.
It doesn't help that this sort of thing is outside my normal range of talks, which has been strictly physics-based. This broader public intellectual stuff isn't something I have a great deal of experience speaking about. I do write in that vein here, though, and since blogging is my obvious subject for this, I might as well…

This is just plain cool! It's amazing how intuitive data can be when plotted visually. And as of Tax Day, you can plot your own data on a stripped-down version of this software, thanks to Google, which bought Trendalyzer from Gapminder in 2007. I can hardly wait to try this out for myself. . .
drorzel | April 25, 2008Given the amount of time I've spent writing about academic issues this week, it's only fitting that the science story getting the most play is about math education. Ed Yong provides a detailed explanation, and Kenneth Chang summarizes the work in the New York Times. Here's Ed's introduction:
Except they don't really work. A new study shows that far from easily grasping mathematical concepts, students who are fed a diet of real-world problems fail to apply their knowledge to new situations. Instead, and against all expectations, they were much more likely to transfer their skills if they were…
catdynamics | April 24, 2008the mystery of the "box" in Syria that was bombed by the Israelis was claimed to be a North Korean design nuclear reactor
the LA Times originally leaked the news of the briefing, claiming there was video evidence showing the interior and the top of a Yongbyon type reactor, and presence of "Korean looking" scientists...
There's a lot of rubbish being written about this.
The Yongbyon reactor is a Plutonium production reactor.
It runs at ~ 5 MW(e), but is not very efficient.
It is a Magnox type reactor - ripoff of the old Calder Hall UK reactor.
The Magnox design works with natural uranium - no…
drorzel | April 24, 2008We had a great time on our visit to Japan last summer, but we had one incredibly frustrating experience, on our first day in Yokohama. We couldn't bring three full weeks' worth of clothing with us, so we brought a bit more than one week's worth, and planned to get things cleaned there. The hotel laundry rates were outlandish, so we loaded up a suitcase with dirty laundry, and when we got to Yokohama, we asked directions to a local laundromat (Japanese word: "ko-in ran-da-ri," or "coin laundry"). The nice lady at the hotel desk gave us a tourist map, with a route indicated on it.
This created…
oracknows | April 24, 2008Yesterday, I did a rather long post that used as its introduction an assertion by bioethicist Arthur Caplan in a review of the anti-evolution propaganda movie Expelled! that the claim that Darwinism led more or less directly to the Holocaust is a form of Holocaust denial. In my post, I concluded that I don't agree with that assertion and that likening Ben Stein's claims in the movie actually weakened his otherwise excellent article that appropriately pointed out the inherent immorality and dishonesty in the way the movie links Darwinism to the Holocaust. To my surprise, Dr. Caplan actually…
awild | April 23, 2008Yesterday I received the sad news that Roy Snelling, one of the most significant figures in modern myrmecology, has passed on. He was on an expedition in Kenya and apparently suffered a heart attack in his sleep.
Roy's prolific career as a curator at the Natural History Museum of Los Angeles County produced dozens of studies on the taxonomy of bees, wasps, and especially ants. Among other accomplishments, his works are the primary reference for the honeypot ants of North America, numerous groups of carpenter ants, and the entire Chilean myrmecofauna. Roy was a devoted desert rat, an…
pharyngula | April 23, 2008
The title gets the principal objection of any creationist out of the way: yes, this population of Podarcis sicula is still made up of lizards, but they're a different kind of lizard now. Evolution works.
Here's the story: in 1971, scientists started an experiment. They took 5 male lizards and 5 female lizards of the species Podarcis sicula from a tiny Adriatic island called Pod Kopiste, 0.09km2, and they placed them on an even tinier island, Pod Mrcaru, 0.03km2, which was also inhabited by another lizard species, Podarcis melisellensis. Then a war broke out, the Croatian War of Independence…
oracknows | April 23, 2008I knew there was a reason why I like bioethicist Art Caplan.
Leave it to him not to be afraid not only to wander a bit afield of medicine than usual but also to call it as he sees it, mainly his argument for why Expelled! and its claim that "Darwinism" led directly to the Holocaust is not only historically incorrect but a form of Holocaust denial. I don't quite agree with him, but he makes a compelling argument:
The movie seeks to explain why, as a matter of freedom of speech, intelligent design should be taught in America's science classrooms and presented in America's publicly funded…
razib | April 22, 2008Seems like both the Republican nominee and the likely Democratic nominee entertain the autism and vaccination "hypothesis". I don't follow politics very closely, this sort of comment really disturbs me....

oracknows | April 22, 2008Yesterday I came across a blog exchange between Dr. Jekyll & Mrs. Hydeand fellow SBer Physioprof about principal investigators (PIs) who still do experiments in the lab. For those not in the science business, a "principal investigator" is in general the faculty member who runs the lab and whose grants fund the salaries of the postdocs, graduate students, and technicians working in the lab. J&H pointed out (correctly) that few PIs who have been faculty more than five years do any actual lab work anymore and described the case of a PI who persists in doing experiments himself,…
catdynamics | April 21, 2008I was just pondering the appalling lack of interesting science news the other day, and then I got back home and found these: CSI Ambleside...
The DAMA collaboration is claiming strong evidence for WIMPy Cold Dark Matter, based on an annual modulation in their scintillator experiment.
Ah, I was wondering why Stanford had a non-detection by their CDM detector group as a lead news item last week.
Sean has rounded up a guest blogger to explain this result, or lack thereof.
There is a new class of high critical temperature superconductors.
