Not only these nasty little fish are vicious, but scientists have discovered that those bloody piranhas can talk to each other. They use three sounds, each of them meaning a different thing. One of the sounds is a bark used to intimidate rivals. The other two are drumming songs produced when they attack each other for food. [...]

Sometimes, a fish out of water doesn’t feel like a fish out of water—at least if it’s a Pacific leaping blenny (pictured). For the first time, scientists have closely studied the land-dwelling fish, which hops about the rocky coastlines of Micronesia (see map). The new study revealed that the “walking” fish are amazingly agile on land, where they engage [...]
Way back in 1897, someone from the Bellevue Hospital Medical College in New York City buried a time capsule stuffed with bacteria in one of the buildings cornerstones. It was lost for well over a century. But in more recent years, New York University made plans to tear the building down and discovered the long-lost [...]
Just a few of the mistakes that wouldn’t have been made by an intelligent designer: 1. Humans have the highest perinatal mortality rate of any of the great apes. Without good medical care, the commonest cause of death in Homo sapiens is child-birth. In the other great apes, perinatal death for mothers and babies is [...]
Humans, like all other organisms on Earth, are subject to the pressures of evolution. New research suggests that even in relatively modern societies, humans are still changing and evolving in response to the environment. “Whether humans could or could not evolve in modern times could have interesting implications,” study researcher Emmanuel Milot, of the University of Quebec in Montreal, told LiveScience. [...]
This chart depicts the public acceptance of evolution theory in 34 countries in 2005. Adults were asked to respond to the statement: “Human beings, as we know them, developed from earlier species of animals.” The percentage of respondents who believed this to be true is marked in blue; those who believed it to be false, [...]
This video, captured by University of California Santa Cruz professor Giacomo Bernardi, shows an orange-dotted tuskfish (Choerodon anchorago) cracking open a clam by throwing it against a rock. Other fish from the wrasse family have also been observed using similar techniques to crack open clams. These include the blackspot tuskfish (Choerodon schoenleinii), yellowhead wrasse (Halichoeres [...]
