Life is like a 2πr.

Our deepest fear is not that we are inadequate. Our deepest fear is that we are powerful beyond measure. We ask ourselves, Who am I to be brilliant, gorgeous, talented, fabulous? Actually, who are you not to be? We were born to make manifest the glory of God that is within us. It's not just in some of us; it's in everyone. And as we let our own light shine, we unconsciously give other people permission to do the same.

60-Second Science - January 30, 2008

Reptile Sex Determination Is Hot Topic

Every expectant mother gets asked the same question: boy or girl? For mammals like us, it’s an easy call. Two X chromosomes you get pink booties. X and a Y you get blue. But for some reptiles, the answer depends on the weather. Well, on the temperature to be precise. For many lizards and turtles and gators, the sex of the hatchlings depends on the temperature in the nest where the eggs incubate.

But why would animals bother with such a seemingly slapdash system for assigning sex? The only logical answer is: there must be some benefit. Each sex must fare better at the temperature that tends to produce that sex. A fine theory, but no one has been able to test it. Until now.

In the January 20 online issue of Nature, scientists at Iowa State University describe how they used hormones to produce lizards with the “wrong sex”—animals that came out male even though they were incubated at the female temperature. And vice versa. They found that females born and raised at the female temperature made more babies than females hatched at the wrong, male temperature. Ditto for the males. Call it the Goldilocks principle.  You’re born at a temperature that’s just right—at least if you’re a lizard.

60-Second Science - January 31, 2008

Put A Pullet In Your Tank

The search for alternative fuels to gasoline has led to surprising possibilities—for instance, the waste oil from making French fries.  But one of the most unusual alternative fuel candidates might be chicken fat. Yes, chicken fat, also called schmaltz.  So if you make chicken soup you might have a valuable resource in your kitchen—besides the actual soup.

Chemical engineers at the University of Arkansas report that when chicken fat is combined with methanol under very high temperatures and pressure (known as supercritical conditions) they got biodiesel.  The method converted 89 percent of the chicken fat to biodiesel. The research was done as part of a master’s thesis project by chemical engineering student Brent Schulte.

Many people have high hopes for biodiesel as a replacement for fossil fuels, because it uses renewable resources such as plant oils, or in this case chicken fat, of which there is certainly no shortage. The hunt for biodiesel may mostly take place outdoors.  But the potential of French fry flotsam and chicken fat also means the search can sometimes end in the kitchen.
