The article Space Laser Spies for Woodpeckers by Jonathan Amos for the BBC caught my eye today due to the way that I woke up this morning. I’m home in New Jersey for the holidays, and the back side of my parents house is wood so we’ve had a few woodpeckers stop by in the past.

This morning I fell out of bed, startled by what sounded like an attack from robotic woodpeckers. I stumbled out into the hall, only to figure out in my half-asleep state that the noise was radiating from the inside of the house, from the plumbing. Following the noise, I found my Mom in the basement doing laundry. Apparently the noise the sink next to the washer makes is very similar to a robotic woodpecker attack. I know you all appreciated that little anecdote, but now on to the scientific side of woodpeckers.

Researchers at the University of Idaho are developing lasers that can be attached to satellites to woodpeckers in the state to determine which parts of the forests they favor. The researchers hope the satellite guided lasers will be a better way to track the woodpecker, which is an indicator species. Being an indicator species means that if the woodpecker is healthy and thriving in different parts of the forest, then it is likely that the forest itself is healthy and doing well.

If the laser-satellites prove to be a successful way of surveying for a species, it could eliminate more labor-intensive and costly means of surveying like sending people into the forest on foot to assess the environment’s health. This is an instance where I have to say, even though we still don’t have flying cars, we are definitely living in the future.

As a left handed person I found this article: ‘Left handed’ coiling snails survive more snake attacks by the BBC’s Victoria Gill, pretty interesting. I love hearing stories of left handed superiority. According to this article, a certain species of snail that has shells that coil either clockwise or counterclockwise is experiencing natural selection due to their shell orientation.

Due to the way snakes suck a snail out of its shell, and the way snakes jaws are formed, only snails that have shells that coil to the right are susceptible to predation. Snakes just can’t suck a snail out of a shell that coils to the left. Ha! Left handed dominance! According to researchers, the snails are starting to branch off into their own species, because eliminating the threat from snakes has been really beneficial for their population.

I’d also like to take a moment to point out that the idea that left handed people are sadistic is a myth. The word sinistrality is used to refer to left handed people because it is derived from the Latin word sinestra which means left handedness. Nothing to do with demons, sorry.

I take pride in being left handed but it can be a pain at times (like when I was learning how to write). Apparently left handed people have a shorter life span than right handed people based on accidents caused by using tools, and equipment designed for right handed people. I guess I better watch out.

But I do have good company in my left handed ways: Ronald Reagan and Bill Clinton (the likable Presidents!) Joan of Arc, Leonardo da Vinci, Michelangelo, Paul McCartney, Charlie Chaplin, Robert DeNiro, Cary Grant, and Marilyn Monroe (lots of others too I just found these the most interesting.)
