It is winter in Wisconsin, and it has arrived with a blizzardy vengeance. My family and I are snowed in for the second day, and as I write this I am trying not to think of the twelve plus inches of snow that covers my driveway. I am afraid to measure the height of the drifts.
The world outside my window is beautiful. Tree limbs and fence posts are frosted in white. There is a LOT of snow out there, and that made me stop and think, there is an awful lot of uniqueness out there. IF every snowflake is unique. And according to a local Wisconsin snowflake expert, University of Wisconsin, Madison, meteorology professor Pao Wang, they aren’t. Continue reading “Uniquely Buried in a Wisconsin”
Imagine playing a simple game in a virtual-reality setting. You move an avatar around a room trying to entice your opponent’s avatar to move closer to you when you are in certain spot. Meanwhile, 12 km away, cameras track your opponent’s movements around an arena that also contains a robotic representation of you. The cameras are telling your opponent’s avatar where to move in your virtual reality setting based on where they move in their actual setting.
My daughter has been actively planning her birthday for about three weeks now (and she still has almost two months to wait). At the top of her wish list this year? Hand sanitizer. As my kids headed back to school this week, I noticed that one of the most popular pieces of backpack “bling” among her little friends was little bottles of: you guessed it, hand sanitizer. In bright colored silicone covers, with yummy sounding scents, little bottles of hand sanitizer bounced along on the backpacks of a lot of the youngsters walking into the school.
My seven year old daughter has a necklace I made her that says “Dandelion Girl” . I made it for her because she remains enamored with these cheerful yellow flowers despite other people’s best attempts to disillusion her. To her they are not weeds, but pretty flowers that turn to a white puff ball that a nature-made toy. Imagine my surprise when I came across an article referring to the genetics of “Dandelion Children”.
This week science lost a celebrity of the most unusual sort. Known to people around the world as Lonesome George, he was recognized as the last living member of his subspecies, the Pinta giant tortoise (Geochelone abingdoni) one of the giant tortoises of the Galapagos Islands. These slow and steady creatures hold a special place in science history. Observing differences between the giant tortoise populations of different Galapagos Islands helped a young Charles Darwin develop his theory of evolution. 
The study, made available online ahead of publication (1), found that from a very early age, people associate sweeten drinks with salty and higher fat foods such as pizza and French fries (or chips). Perhaps partly as a result of this association, young people (ages 19–23 years) viewed unfavorably the pairing of a sweetened drink with raw or cooked vegetables. The test subjects showed strong reactions (either positive or negative) to the pairing of sweetened drinks with certain foods. In contrast, water didn’t evoke strong any reactions indicating that it was viewed as reasonable complement to most food. 
The worst part was I knew I had only myself to blame. 
Forgetting. Forgetting your address; your spouse; your children; your friends; your life. It is something that none of us want to think about, but it hangs over some of us like a specter. Can’t remember if you fed the cat? Where you put your car keys? Did you forget to pack your lunch or return a phone call? Maybe you are trying to do too many things at once, or maybe you are tired. There are lots of perfectly normal reasons why we all forget things from time to time, but every time I forget something there is a nagging voice in my head saying, “Maybe it is something else.”
