Nature versus Nurture: Are Champion RaceHorses Born Or Made?

Dec 27 2007 Published by under Brain & Behavior, Genetics, Horses, Journal Club

Seattle Slew (1974-2002), the only undefeated horse to win the Triple Crown (1977).

ResearchBlogging.org

I have been thinking about a paper that was published last week, that analyzed the effects of "nature versus nurture" on the development of a champion racehorse. In short, this paper found that the effects of a horse's pedigree is minor when compared to its environment .. the combined effects of training, diet, choice of races entered, jockey skill and of course, injuries, which are unpredictable. In short, the exorbitant stud fees paid to breed a mare to a prized stallion are not an honest signal of the stallion's genetic quality. However, upon reading this paper, I think the situation is more complicated than how the authors present it.

Amur (Siberian) tiger, Panthera tigris altaica.
Tigers are most commonly poached for their fur and body parts, which are used in traditional Chinese medicine. It is estimated that in 1991 alone, one-third of the Siberian tiger population was killed to meet the demand for their bones and other parts used in this practice.

Science in Slow Motion

Have you ever seen the details how a lighter lights up? How a face is deformed after a punch or slap? How a water balloon explodes? How a rocket is fired and how a gun is fired? How an apple, banana, golf ball, concrete slab and other things are shot through with a bullet? How an arbalest is fired? How a bomb explodes? All these things and more can be seen on this streaming video. My favorite is watching the pigeon take off from its perch. [6:33]

Under the Weather

Dec 26 2007 Published by under Uncategorized

I am sorry that my writing has slowed, but I am sick right now with a nasty cough. I get this same cough every year at this time (is it bronchitis? or "walking" pneumonia? I have had pneumonia several times so far). This cough hangs on for many weeks, or even months, and makes me exhausted and utterly miserable.
Anyway, I've been in bed all day, except when I venture out to take care of my birds and to care for the animals I am petsitting over the holidays. The worst thing is that I am not so ill as to sleep all the time -- quite the opposite, because I cannot sleep at all, which makes me think I could be manic right now. In addition to my sleeplessness, I am going crazy because I am in my apartment without any internet access, unless you consider 20 minutes total of internet access that is sprinkled throughout a 24 hour period of time to be satisfactory.
