There is an interesting NYTimes article about a researcher who studies about fireflies.
Different species of fireflies have different patterns of flashing, but only the males flash while flying! The females usually sit in the grass observing the males, often looking for a male of their own species to respond to. Often you can find several different species of fireflies in the same field. This researcher studies the flashing of the fireflies and what the different patterns might mean.

Journal of Visualized Experiments (JoVE): Peer-reviewed video journal articles
Remember that Large Hadron Rap that blew up on YouTube? A fellow classmate in my writing about science course wrote about “viral” videos like that one for his term paper. It’s a really cool idea, since he took the angle that education about science could benefit from more videos like these.
From another angle, scientists could educate other scientists through video as well.
The Journal of Visualized Experiments is unique in that all of their publications are in video format. There is an accompanying text article, but the video is the centerpiece. Many of the articles are about techniques in labs and procedures, but I would be interested to see what else can be done in this style.
From reading the “About JoVE” page, JoVE is all about “rapid knowledge transfer,” “addressing complexity,” “lifting the laboratory time sink,” “integrating time,” and “a new movement in science publishing.”
One thing I would think would be interesting to see in video format was a topic that Joe Thornton recently gave a talk about as part of the Darwin Speaker Series (the same one that Rosemary Grant came for).
His lab investigates evolutionary mechanisms through experiments with receptor proteins and gene function. He spoke to us about a series of experiments where they were attempting to reconstruct the evolutionary pathways of 2 receptors from a common ancestor.
Internet video is still new in terms of using it as a learning tool, but it has tons of appeal nowadays since it is so accessible. Every time I’ve given a presentation, I think about how I could use a video from YouTube to break up the monotony. Maybe there will come a day when most of my presentations will be made up of various videos!
As part of Columbia University’s Darwin Speaker Series, Rosemary Grant of Princeton University came to speak on April 14th, 2009 about evolution in Darwin’s finches.

This year being the 150th anniversary of On the Origin of Species, and the 200th anniversary of Darwin’s birth, it was fitting for Rosemary Grant to speak about her research on the island Daphne in the Galapagos Islands. The finches have radiated into over a dozen diagnosable species, some that share habitats and some living alone on their islands. The islands are so isolated that migrations are rare, but when they do occur, researchers are there to observe the events.
Rosemary is an interesting woman, and her husband and research partner, Peter, an interesting man. People may unknowingly assume they are a typical cute older couple when passing them on the street. But what they have seen during their years of research on a few small islands may surpass in scope anything we may hope to witness in any one of our lifetimes.

Detecting lies in the 21st century

I am currently reading the book The Best American Science Writing 2007, and in it was an article about lie detecting by Robin Marantz Henig entitled Looking for the lie that was published in the New York Times Magazine. (Just so you know, there is no scientific evidence to suggest that polygraphs can detect lies at very high accuracy.)

Towards the end of her piece, Henig discusses some of the evolutionary implications pertaining to deception and the development of the brain. Advanced social interactions are complex and often deception needs to be part of the equation and might be somewhat related to skills that make individuals socially adapted and intelligent.
This idea is interesting because it would explain a lot of the selfish behavior that we see in humans today. Social groups that are small enough may not suffer as much from serious deceptive offences, though they definitely have their share of gossiping, etc.
But as social groups get bigger, relationships are not as much defined by kinship but by association and profession. Being able to lie or deceive may have become adaptive in these settings where it would be the difference between gaining an advantage over a competitor or getting the short end of the stick.
