Science
Here's something that bugs me. Instead of emphasizing the real significance of the find, a discovery like the "Mars ant" Martialis heureka is usually condensed down to "Wow, this ant is weird!".
I've pasted below a sampling of leads:
Newly-Discovered Bizarre Ant - Boing Boing
'Ant From Mars' Discovered in Amazon Rainforest - Fox News
'Ant from Mars' found in Amazon jungle - Science News
But weirdness misses the point. We have weird ants already. The suicidal exploding Camponotus is plenty weird. So are the gliding ants, and the ants that swim. The real story here is the…
(Over the course of this week, I'm going to post a handful of things about talks that struck me as particularly interesting at last week's conference. The order will be chosen based on how much time I think I will have to write them up, given SteelyKid's demands for attention...)
On Thursday, the Science in the 21st Century conference featured a lawyer. Well, a law professor, anyway-- Beth Noveck of the NYU Law School gave a talk on Science in Government 2.0 (FriendFeed microblogging). This wasn't as odd as you might think at a Web 2.0 kind of meeting, because she talked about her involvement…
Everybody's all abuzz about this picture:
This may be the first image of a planet around a sun-like star. May be, mind-- it looks likely, but there are still a lot of caveats. If it is a planet, and not a dim background star, it's got about eight times the mass of Jupiter, and is orbiting at eleven times the radius of Neptune's orbit. Those are a little hard to explain.
Still, isn't it cool to be living in the future?
Phil Plait has all the details.
I like computers, really I do. Computational physics is a good thing. However, there is a small problem. The problem is that there seems to be a large number of people out there that treat numerical methods and simulations as something different than theoretical calculations. You can tell who these people are because they refer to simulations as "experiments". But what do these simulations really do in science? What is science really all about?
**Science**
To me, science is all about models. Making models, testing models, upgrading models. Models. Some examples are the model of…
There was this commercial on the radio about Trane heating and cooling units. The ad claimed that the units could use up to 50% less energy than your existing unit. This started me thinking (because before that I was in a complete state of non-thinking). Do you remember the Y2K problem? Basically, when people started writing programs back before Star Wars they had to be very conservative. The hardware of the time did not afford the programmers to have frivolous code. To conserve, they only used the last two digits to represent the year (1970 was represented as 70). Obviously this…
Martialis heureka Rabeling & Verhaagh 2008
drawing by the inimitable Barrett Klein for PNAS
Most scientific discoveries these days emerge through carefully planned and controlled research programs. Every now and again, though, something unexpected just pops up in a distant tropical jungle. Martialis heureka is a fantastic discovery of that old-fashioned kind. This little ant simply walked up to myrmecologist Christian Rabeling in the Brazilian Amazon. It is not only a new species, but an entirely different sort of ant than anything known before.
The remarkable find was…
If you listen to people talking about (or read people blogging about) new ways of doing things, you'll frequently hear references to Science or Academia as if they were vast but monolithic entities existing in their own right. Statements like "The culture of Science does not reward open access..." or "Modern Academia does not reward high-risk research..." are quite common. They also are often paired with a call for external relief, usually through some government mandate-- "We need funding agencies to make this a condition of grant funding."
I always find these statements faintly annoying,…
As you might have guessed from yesterday's tease, the folks at ScienceDebate 2008 have now managed to get answers from the McCain campaign (to go with Obama's froma few weeks ago). Which means that while you may never see them answering science questions on a stage together, you can put them head-to-head on the Web, and see which you like better.
Of course, the key question regarding McCain's answers is "How long does it take him to mention elements of his biography?" The answer: There are 186 words before you get to:
I am uniquely qualified to lead our nation during this technological…

"One cannot have too many good bird books"
--Ralph Hoffmann, Birds of the Pacific States (1927).
The Birdbooker Report is a special weekly report of wide variety of science, nature and behavior books that are or soon will be available for purchase. This report is written by one of my Seattle bird pals, Ian "Birdbooker" Paulsen, and is published here for your enjoyment. Here's this week's issue of the Birdbooker Report by which lists ecology, environment, natural history and bird books that are (or will…
The new father, he of uncertain principles, has analyzed whether his science posts gain viewership over time. My biggest problem with writing scientific content into posts is that when I do that it totally messes up my google searching. I mean when I do that then I end up finding my own blog post when I search for something I'm trying ton understand. On the other hand, it saves a click because I can be pretty certain that the link to my blog doesn't lead to the answer I'm looking for (or if it does it's time to get my memory checked out.)
Suppose I am working on a problem and I wish to calculate the density of something. I measure the mass to be *m* = 24.5 grams and the volume is *V* = 10 cm3. In this case the density would be:
![Sigfig 1](http://scienceblogs.com/dotphysics/wp-content/uploads/2008/09/sigfig-1…)
ALERT! ALERT! ALERT! This is not a test!!!! Something is drastically wrong! Clearly I messed up. How can I have the mass measured to **3** significant figures, the volume measured to **1** significant figure, but the density calculated to **3** significant figures? Isn't this a violation of some fundamental…
Brain Greene had a useful op-ed in yesterday's New York Times. He's discussing all the fuss about the Large Hadron Collider:
After more than a decade of development and construction, involving thousands of scientists from dozens of countries at a cost of some $8 billion, the "on" switch for the collider was thrown this week. So what we can expect?
The collider's workings are straightforward: at full power, trillions of protons will be injected into the otherwise empty track and set racing in opposite directions at speeds exceeding 99.999999 percent of the speed of light -- fast enough so…
Prionocyphon Marsh Beetle (Scirtidae)
New York
Scirtidae is a small family of mostly small beetles found in wet, swampy habitats all over the world. Taxonomists find them to be difficult creatures, the larvae are archaic in appearance but the adults share some similarities with the elateriforms- click beetles, fireflies, and the like. Recent research based on ribosomal DNA sequences showed why their evolutionary relationships have been so hard to peg. Rather than fitting neatly inside one of the 4 beetle suborders, these insects are surprisingly old, diverging from the lineage that led…
If you have any doubt about how dangerous Hurricane Ike is likely to be, I've got some pictures for you. These pictures were taken within the past two hours, on the shoreline along the grounds of Naval Air Station Pensacola.
This is a sheltered shoreline, protected by both barrier islands and sandbars, and typical wave heights run under one foot. Currently, they're running at about 3 feet, on top of a water level that looks to be at least 3-5 feet above where it should be. So far, this storm has done more to reshape the beaches I looked at than Gustav did, and Gustav came closer and was…
Yesterday the large hadron collider started up successfully, and the world did not end. But it will still be months before we have exciting collision data, so don't hold your breath waiting for that Higgs boson - unless you want to buy a stuffed one at Particle Zoo:
Wait - a Higgs boson costs just $9.75?! Someone should have told CERN before they spent all those billions of Euros!
If the Higgs boson is too trendy for you, Julie at Particle Zoo also offers a Z boson, which looks kinda like a Pac-Man ghost, or one of the three neutrinos, which resemble the disembodied heads of Ninja turtles…
You have to give Uncommon Descent poster DaveScot credit. He's not one of life's overly specialized intellects. He's a good, old fashioned generalist, able to talk about absolutely any area of science with exactly the same degree of spectacular incompetence. Today, he's turned his attention to the intersection of mental health and substance abuse.
DaveScot's uninformed ire was sparked, in this particular case, by a news report discussing a paper that recently appeared in the Journal of Clinical Psychiatry. According to the report, the researchers found a strong association between cannabis…

It is predicted that the world will end at 3am ET when CERN's Large Hadron Supercollider was turned on, creating a giant black hole that will suck the earth into it, destroying everything. Since we still exist, I guess it's time to sing a little, right? [4:49]

I thought so. You should know that they have flipped the switch on the Large Hadron Collider, and no disasters yet. Of course, all they've done so far is whirl around in circles at near the speed of light, with no big high-energy collisions yet … the gang at Cosmic Variance have been live-blogging the LHC tests, so watch that to see what's new.
My kids like books. Especially when they are going to bed. I let my daughter pick a book and she picked "Clam-I-am. All About the BEACH" by Trish Rabe. It is nice, it rhymes. The pictures are pretty. Then I get to this page:

So, the ocean is blue because of the sky? How do you get green oceans? How about brown (I live in Louisiana, trust me - the gulf of Mexico can be brown)? What about when you are underwater, everything looks blue. The best answer to why the ocean is blue is that that is what color does…
Here's an example of the power of evolutionary theory. Suefuji et al just published a paper in Biology Letters describing the relationship between the number of queens in an ant nest and the rearing of new reproductives. That'd be a cool enough paper on its own, but there's more. Evolutionary theory makes some specific predictions about when sexuals ought to be produced under different numbers of queens. If the selfish-gene hypotheses of evolution are true, then nests with multiple queens should race to produce sexual brood earlier than nests with single queens. And that is exactly…
