Glow in the Dark Snails

New Research

Bioluminescence is such a cool natural phenomenon. Victoria Gill’s article for the BBC, Snails flash a green alarm light, discusses the newest organism to be discovered with bioluminescent abilities. Basically, bioluminescence is the ability to glow neon colors like a living glow-stick.

Organisms use their glow to scare off predators, and when that doesn’t work, to put the spotlight on the organism that is attacking them so that perhaps another predator will come after it.

The bioluminescent snail are interesting because the actual part of the snail that glows is located inside the shell. The opaque nature of the shell amplifies the color so that its glow is increased and the glow spreads to the entire shell.

The Ever Important Role of Facebook

State of Journalism

Given that I check my Facebook at least a dozen times a day, I think its safe to say that I’m an addict. The more Facebook changes and expands, the more addictive it seems to become – especially with the evolution of the news feed.

This week my professors and colleagues pointed out several examples of social media, particularly Facebook, playing a role in how hard news stories are reported. I think it is definitely safe to say that Facebook is another tool in a reporter’s arsenal to get the scoop on a story, or even just to get a good feel for a situation.

One article that I found particularly jarring because of the way it used Facebook is Ian Shapira’s article for The Washington Post, A Facebook story: A mother’s joy and a family’s sorrow.

In addition to seriously pulling on the heartstrings, I think Shapira’s article also dances around the issue of what happens to your online presence after you die. The issue of “digital death” was raised by my colleague in the UW pro-track program, Marianne English in the article: Madison startup Entrustet helps people control their digital assets from The Isthmus.

Things to think about.

Leaving the Solar System

New Research

There was an interesting story today in the BBC about the NASA space probe Voyager 1, and how it is nearing the edge of our solar system. Voyager 1 has traveled the farthest of all the vessel to be launched from Earth. It will be the first space probe to ever leave our solar system.

What I found so interesting about the Voyager 1 probe is that it was launched in 1977, making it 33 years old. This machine has been collecting and transmitting data about space back to Earth for longer than I have been alive. I think that is pretty amazing, and it is a testament to engineering that NASA’s scientists were able to make a machine that could still function properly after all this time.

Voyager 1 and its partner Voyager 2 were initially launched to survey the outermost planets in our solar system: Jupiter, Saturn, Uranus, and Neptune. Voyager 2 is nowhere near the edge of the solar system however, because after it was finished with the outer planets in 1989 it was put on a much slower course than Voyager 1.

According to researchers, Voyager 1 should cross the threshold outside of our solar system sometime in the next five years, so this story will definitely be coming up in the news again in the future.

Advantages to Being on the Left

My Personal Life, New Research

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.)

Diamond Planet

New Research

New research using NASA’s Spritzer Space Telescope has shown that planets in our galaxy may be more carbon based than others meaning that the ground would be made of diamonds instead of sand (rocks, dirt, essentially what our soil is made of.)
The new planetary discovery, Wasp12b, is a gas giant like Jupiter, and wouldn’t have the water necessary to sustain life. But, just the idea that a planet made of diamonds could exist is definitely fun. Its strange how something that is such a hot commodity on Earth could be so ordinary somewhere else with just a few changes in chemical composition.

I couldn’t do a post about diamonds and not include a little Marilyn Monroe, after all Diamonds Are A Girl’s Best Friend:
