How to speak monkey: The language of cotton-top tamarins - Anne Savage. Cotton-top tamarins are unique in that scientists have spent considerable time studying this critically endangered primate in captive conditions and in the wild. We know more about cotton-top tamarins than just about any callitrichid (marmosets and tamarins). You can read the scientific paper and listen to the calls to learn the meaning of 38 distinct vocalizations. Did you know that cotton-tops like certain foods more than others and that is reflected in the rate of calling (Type C and D chirps)? Cotton-top tamarin are very territorial and we noticed that when we played a Normal Long Call from an unrelated animal the group responded to the call very aggressively.

They would respond with Normal Long Calls and would come running over to investigate where the sound was coming from. In the wild, we noticed that cotton-top tamarins would use Normal Long Calls as a way to avoid neighboring groups. 25 Best Sites for Free Educational Videos.

NOTE: requires Flash to view :| Forks Over Knives examines the profound claim that most, if not all, of the degenerative diseases that afflict us can be controlled, or even reversed, by rejecting our present menu of animal-based and processed foods. Through an examination of the careers of American physician Caldwell Esselstyn and professor of nutritional biochemistry T. Colin Campbell, Forks Over Knives suggests that "most, if not all, of the degenerative diseases that afflict us can be controlled, or even reversed, by rejecting our present menu of animal-based and processed foods. " It also provides an overview of the 20-year China-Cornell-Oxford Project that led to Professor Campbell's findings, outlined in his book, The China Study (2005) in which he suggests that coronary disease, diabetes, obesity, and cancer can be linked to the Western diet of processed and animal-based foods (including all dairy products).

Never met anyone like you - Current obsession: child beauty pageant documentaries. Lately I've gotten fascinated with various documentaries on child beauty pageants; I'm always captivated by trainwrecks, and the more bad parenting and strange little children they have, the more captivated I am. (I'm sure you could put your kid in some sort of pageant and be a decent parent, but the ones in these aren't.) So, here are my summary/reviews of the various documentaries, along with links to where you can watch them for free online. Living Dolls: The Making of a Child Beauty QueenThis is far and away my favorite. Five-year-old Swan Brooner's mother Robin spends countless hours and thousands of dollars getting her ready for pageants, taking on three jobs in order to make it all financially possible. While Swan is put through endless practices in the family's garage, her older sister Silva has the patience of a saint, her older brother Robert (Bubba) is in trouble with the law, and her two-year-old brother Devon sleeps shirtless on the floor.

The average meat eating American will consume 15 cows, 24 hogs, 900 chickens, 12 sheep and 1,000 pounds of birds/fish in their lifetime which is a tremendous amount of animal flesh to be consumed by the human body.

We wanted to see the hidden world behind clothes sold in this country, so we decided to make a T-shirt. We wanted to make an ordinary shirt like the vast majority of the shirts sold in this country — not organic cotton, not hand-sewn in the United States. To figure out how many shirts to make, and to raise money to pay for them, we turned to Kickstarter.

Our goal was to sell 2,000 shirts. In the end, we sold 25,000. (Thanks again to everyone who ordered a shirt. Really. Why A Squirrel? The design on the shirt, a squirrel hoisting a martini glass, is a visual pun: a reference to the phrase “animal spirits” made famous by the economist John Maynard Keynes. As Planet Money’s David Kestenbaum put it recently: “Keynes’ idea was that there’s more to the markets than just numbers; there are people and emotions making decisions. 10 Reporters, 3 Continents, 1 Archipelago We flew drones over Mississippi.

The Language Learner’s NOT To Do List | Language Mastery. To do lists seem like a good idea in theory, but they have one major disadvantage: there is an infinite number of potential to do items. With this in mind, Timothy Ferriss, best-selling author of The 4-Hour Workweek (and a speaker of 6 languages), recommends “not to do lists” instead. Since they isolate a finite set of behaviors that are getting between you and your goals, they are far more effective than traditional to do lists. This tool applies perfectly to language learning, where most learners waste a lot of time on ineffective methods and bad materials.
