I have a couple of identical twin cousins who, for much of their young life, were indistinguishable to the rest of the family. Even their parents couldn't tell them apart. In fact, my aunt once told me that she wasn't entirely sure that their names were even correct as she had no idea which was whic .....

Another example can be found in evolution. A population of reptiles accrues traits over time that more resemble a dinosaur than a reptile so we call them dinosaurs. Over more time, a population grows feathers of such a type that enables it to glide, then to fly. Finally a human domesticates a popula .....

The us that awakens each morning is an epiphenomenal entity that arises from the electrochemical processes of the cognitive part of the brain, which, in turn, are dependent on its anatomy and physiology. To use a computer analogy, we are a program that gets rebooted each morning. However, the entity .....

Speaking of things ecological, I've been composting kitchen scraps with earthworms for a few months now. Thus far, I've gotten about 40 pounds of nice compost from an input of kitchen garbage, dry yard waste and old newspapers. My worm community has tripled in size too. When the weather warms I'm go .....

As little as 10% of the energy is passed onto the next tropic level, you mean. We lose 90% of it.

60 is not that old. Hell, she was the same age as me! I hope I age as well as my neighbor across the street. She is 95 and was out shoveling snow the other day. Just goes to show you that riches and fame don't matter much where death is concerned. Even if you live in a country with the best doctors .....

George Michael wasn't a role model by any stretch of the imagination but I have to admit that I liked some of his music, maybe because it was popular when I first got out of the Army and was in college. Dead at 53, probably from his sex, drugs and rock and roll lifestyle.

Regardless of the occasional ice sheet breaking free, there is still a net increase in ice accumulation in Antarctica.

an increase in Antarctic snow accumulation that began 10,000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers.

Those who say that global warming is going to melt all the ice and and cause sea levels to rise and flood all of our cities oftentimes don't understand the big picture. They exclaim that if the Antarctic ice sheet melts, sea levels will rise 60 meters. However, is this really going to happen? Did yo .....

I'm not prescribing moral codes, I'm describing them. Essentially, I'm saying that what works, works. Think twice before you go trying to change things that have allowed a lineage to survive since life began. That is, unless you know (not believe) that you have the mental capacity to see beyond the .....

Until recently, it took several years for a newly-coined word to gain general acceptance. Now, with social media, hundreds of new terms and phrases become commonly used. If you want to coin something just find a concept that is not precisely represented by a known word in English, make up a term and .....
