illustration: silverbackblog.com If you're a fish living in a cave, having eyes isn't going to be particularly useful to you. Eyes and the parts of the brain handling vision need a lot of energy to work in the form of food. In theory, evolution would have cave-dwelling fish do away with vision altogether. That could be what has happened to a species of fish known as the Mexican tetra. That

That Wikipedia isn't a reliable source isn't exactly news to many of you, but despite its faults it is the most widely used online encyclopedia and the sixth most popular website globally. Yet stories of edit wars, vandalism and admins going rogue to keep their pet topics hostage so others couldn't edit them, are rampant and they should undermine Wiki's credibility. Yet people still trust it to

Many different datasets can lead to the same bar graph. A recent criticism, published in PLoS Biology, has called into question the use of bar and line graphs to represent continuous data. The authors list 3 flaws inherent to bar and line graphs. Bar graphs hide the underlying nuances of continuous data, summarizing the differences. Things like distribution patters and sample sizes are

A paper by Dutch psychologists describes 4 studies that show that depictions in media of scientific progress made in battling climate change has an unexpected effect in people of decreasing interest in behaving in environmentally friendly ways. The argument is that overly-positive depictions of science might in the reader enhance perceptions of order, which reduces motivations to act in

The person thinks of a specific word, then the input is fed to a computer, the computer takes the signal and turns it into binary data. That gets e-mailed to another computer

Capuchin monkeys were used in this study. Here is an interesting video that demonstrates so well that animals have a sense of fairness.

Nanobeads attach to E. coli (left) and S. aureus (right). There might be a new futuristic way of fighting viruses and bacteria. Instead of taking antibiotics, which can have side effects and might not be that effective, in the future we might hook ourselves to a device that uses magnetic nanobeads coated with specific proteins, which attach to the surfaces of pathogens.

Last summer all of the snow covering Greenland melted in just a few days, causing massive floods. Satellite images showed Greenland going from a mostly snow covered island into a dark rocky one. As Greenland loses more snow, it also receives more heat from the sun. Snow acts as a mirror, reflecting the sun's infrared rays back into space. As Greenland loses snow, it receives more heat, more snow

What happened to 9 hikers on the night of February 2, 1959 in the chilly Ural mountains in Russia? Does this mystery have a rational explanation or will we forever have to be satisfied with only the official but eerie answer that "a compelling unknown force" was the cause of their deaths?
