Gobble

by teofilo in Gambler's House

So, turkeys.  I mentioned in an earlier post that there’s been an important new paper about turkeys published in PNAS.  It’s been mentioned in two good media accounts linked by Southwestern Archaeology Today in two separate posts.  Unlike most PNAS articles, this one is Open Access, so both the article itself and its supplement are [...]...

Unraveling Arthropoda

by Michael Bok in Arthropoda

A new paper, published online in Nature this week, aims to resolve long-standing disputes within Arthropod phylogenetics. This work offers strong evidence for, and opens new, perplexing questions about, the deep evolutionary history of arthropods.
The phylum Arthropoda consists of four major subphyla:

Chelicerata – Arachnids, horseshoe crabs, sea spiders.
Myriapoda – Centipedes, millipedes.

This made me smile

by Kris-Stella in Coffee Shop Philosophy

Thanks to Jezebel via Emily, here's a brilliant take on Beyonce's "Single Ladies": "Scholar Ladies". The geek in me approves! "If you learned it then you should have got an A on it." On a related note (as if you needed any more convincing to do your homework), let's bring up a discussion of girls and math performance. Did you know that the gender gap in mathematics is linked tomore general national rates of gender equality? In Iceland, girls outperform guys at math. Here's more:Hyde, J., & Mertz........

Heart Rate Variability: Depression Monitor for Work?

by mc in begin to dig (b2d)

we may be able to use heart rate variability (HRV) to help detect and so address depression - another stressor. A 2009 study has shown promising results in terms of using HRV to detect if someone is still suffering from the effects of depression. The study looked at folks who were returning to work after being off for depression, and having been cleared to come back to work.... Read more »

Navajo Has Two and a Half Words for Snow

by teofilo in Gambler's House

It’s snowing like crazy here in New Jersey right now.  Rutgers canceled all classes today and morning classes tomorrow, so I’ve got a lot of unexpected time off.  Seeing all this snow is reminding me, as always, of Navajo linguistics.  Words for “snow” play a disproportionately important role in understanding the history and dialectology of [...]...

Today the American Psychiatric Association released a draft of the major changes that are expected in the new version of the Diagnostic and Statistical Manual of Mental Disorder – 5th Edition (DSM-V).

Immunization for Addiction: the Cocaine Vaccine

by Evil Monkey in Neurotopia

Every so often this cocaine vaccine issue rears its head again. I saw it again just the other day. The problem is, of course, the tendency of the media (ain't it always the media) to say something like "OMG THIS IS TEH CURE FOR EVERYTHING!" in response to one small study. And who knows, the cocaine vaccine may indeed be the cure for everything, but Sci needs to see some big trials before she gets her hopes up. As it is, the studies I have seen provide some interesting clues, but also provide........ Read more »

I have a big beak and a small tongue: Hornbill feeding

by Zen Faulkes in NeuroDojo

In the movie Roxanne, Steve Martin’s Cyrano-esque character has a scene where he’s supposed to drink from a small fluted wine glass, but his character’s large schnoz makes it impossible. That’s sort of the task faced by several birds species with large, lengthy bills.

Feeding is no small task for birds. Keep in mind that birds have no hands to manipulate their food, and a bird’s bill is completely inflexible. Imagine trying to eat without moving your lips.

Hornbills (like Aceros cass........ Read more »

Birds of a feather are bred together: domesticated turkeys in prehistoric SW US

by Rachel in The Sage of Discovery: Exploring the world of food one ingredient at a time

Turkeys have long been an important foodstuff in many parts of the world. In the U.S., not only has our post-colonial society been fueled by this fowl; historically, turkey meat, feathers, and bones have provided important uses for pre-contact Native Americans. But where did these birds come from? By examining the remains of turkeys from [...]... Read more »

Chocolate Milk: The Ideal Post-Exercise Drink?

by Travis Saunders, MSc in Obesity Panacea


For anyone who has spent any time around a gym or even around fervent gym goers, you have probably heard the adage that chocolate milk is the ideal drink of choice post exercise to aid in recovery. In fact, dairy companies have put out commercials advertising the purported athletic benefits of drinking chocolate milk post exercise. I must admit that I personally love a 500ml carton of chocolate milk after my workouts. But is there any evidence to support all the hype?


Now, before I go any fur........ Read more »

On “the real holes in climate science”

[This post is based a question I got in response to a previous post but thought it deserved a short post on its own as there's a few interesting points.]

Is the Evolution Debate Over?

by Johnny in Ecographica

A recent blog post at National Public Radio’s “Cosmos And Culture” by astrophysicist Adam Frank has raised my hackles. The post, titled “The Evolution Debate Is Over; It's Time To Move Forward,” argues that “it's time to put the prejudices that drag down discussion between science and the domains of human spiritual endeavor aside.”
