	Unraveling the mystery of chiton visual systems You'd probably walk past a chiton without even seeing it. These creatures often look like nothing more than another speck of seaweed on the crusty intertidal rocks. But it sees you. At least, if it's one of the species with eyes dotting its plate mail shell.
	Losing their tails provided our ape ancestors with an evolutionary advantage, but we're still paying the price Put the word "evolution" into Google images and the results are largely variations on one theme: Ralph Zallinger's illustration, March of Progress. Running left to right, we see a chimp-like knuckle walker gradually becoming taller and standing erect.
	An evolutionary mystery 125 million years in the making Plant genomics has come a long way since Cold Spring Harbor Laboratory (CSHL) helped sequence the first plant genome. But engineering the perfect crop is still, in many ways, a game of chance. Making the same DNA mutation in two different plants doesn't always give us the crop traits we want. The question is why not? CSHL plant biologists just dug up a reason.

	Study reveals the crow's best friend: Humans A new study from Tel Aviv University (TAU) has examined what happens to birds that are accustomed to living around humans, when their habitat is suddenly emptied of the presence of humans. Among other birds, the researchers tested crows, ringneck parakeets (also known as rose-ringed parakeets) and graceful prinias—and the findings are surprising: While the crows and ringneck parakeets—who are characterized by their tendency to "follow" humans, are already accustomed to the noises they make and feed on their food scraps—decreased their activity, the graceful prinias, which are considered shy, actually increased their activity in the same area.
	Newly discovered protein prevents DNA triplication Every time a cell divides, its DNA is duplicated so that the two daughter cells have the same genetic material as their parent. This means that, millions of times a day, a biochemical wonder takes place in the body: the copying of the DNA molecule. It is a high-precision job carried out by specific proteins and includes systems to protect against potential errors that could lead to diseases such as cancer.
	Study of slowly evolving 'living fossils' reveals key genetic insights In 1859, Charles Darwin coined the term "living fossils" to describe organisms that show little species diversity or physical differences from their ancestors in the fossil record.
