Watch out for that Sun!


I’m not sure this is really a comet (mostly made of ice and dust – but I really don’t know what I am talking about here), but we do have video of something small crashing into the Sun thanks to the Solar Dynamics Observatory. And that is cool.

If you are having trouble seeing the object in the video, the picture below will help you figure out where to look.

Giant swarming schools of squid cause zombie apocalypse

I hope this will help. I have one thing left to do at work today and I cannot get to it until I vent about this headline from boingboing:

Giant schools of swarming squid surround fish photographer

I guarantee that William Strunk, Jr.’s zombie is crawling out of its grave right now in pursuit of Xeni Jardin‘s BRAAAAIIINNNSSSS!*

Just to make me happy (and delay the zombie apocalypse), let’s get rid of the words that are strongly implied by other words in this title. Continue reading “Giant swarming schools of squid cause zombie apocalypse”

Raptorex debate continues

In a previous post about Raptorex kriegsteini I expounded upon Jack Horner’s suggestion that Raptorex is not an example of the Tyranosaur body pattern evolving before gigantic size. Now, Horner and colleagues have published the data behind their critiques in PLoS One:

The recently described small-bodied tyrannosaurid Raptorex kreigsteini is exceptional as its discovery proposes that many of the distinctive anatomical traits of derived tyrannosaurids were acquired in the Early Cretaceous, before the evolution of large body size. . .These findings are consistent with the original sale description of LH PV18 as a juvenile Tarbosaurus from the Upper Cretaceous of Mongolia. Consequently, we suggest that there is currently no evidence to support the conclusion that tyrannosaurid skeletal design first evolved in the Early Cretaceous at small body size.

Best letter response. . .EVER

Charles Bennett has a beef with the wording of an article title in Science“At long last, Gravity Probe B satellite proves Einstein right”.

I find myself frequently repeating to students and the public that science doesn’t “prove” theories. Scientific measurements can only disprove theories or be consistent with them.

Instead of going on about the philosophy of science at length, let’s just quote the spot-on quote from their response:

Bennett is completely correct. It’s an important conceptual point, and we blew it.

Bravo!
