 | The Wildlife Conservation Society and the Panthera Foundation announced plans to establish a 5,000 mile-long "genetic corridor" from Bhutan to Burma that would allow tiger populations to roam freely across landscapes. The corridor, first announced at the United Nations on January 30th, would span eight countries and represent the largest block of tiger habitat left on earth. ...> Full Article |
 | A team of scientists has just left the country to explore a very strange lake in Antarctica; it is filled with, essentially, extra-strength laundry detergent. No, the researchers haven't spilled coffee on their lab coats. They are hunting for extremophiles -- tough little creatures that thrive in conditions too extreme for most other living things. ...> Full Article |

 | The image of the chameleon as a shy creature, using camouflage to conceal themselves has been challenged by new research showing that colour change evolved to attract the attention of other chameleons. ...> Full Article |
 | Compelled to mate, yet firmly attached to the rock, barnacles have evolved the longest penis of any animal for their size - up to eight times their body length - so they can find and fertilize distant neighbours. ...> Full Article |

Although there is unquestionably much left to be discovered about life on Earth, charismatic animals like mammals are usually well documented, and it is rare to find a new species today-especially from a group as intriguing as the elephant-shrews, monogamous mammals found only in Africa with a colorful history of misunderstood ancestry. Like shrews, these small, furry mammals eat mostly insects. Early scientists named them elephant-shrews not because they thought the animals were related to elephants but because of their long, flexible snouts. Ironically, recent molecular research has shown that they are actually more closely related to elephants than to shrews. Members of a supercohort called Afrotheria that evolved in Africa over 100 million years ago, their relatives include elephants, sea cows, and the aardvark. Until recently, only 15 species of elephant-shrews, also called sengis to avoid confusion with true shrews, were known to science. However, in March of 2006, Galen Rathbun of the California Academy of Sciences, Francesco Rovero of the Trento Museum of Natural Sciences, and a team of collaborators confirmed the existence of a new species that lives only in two high-altitude forest blocks in the mountains of south-central Tanzania.

 | The beeps, chirps and whistles made by some hummingbirds and thought to be vocal are actually created by the birds' tail feathers, according to a study by two students at the University of California, Berkeley. ...> Full Article |
 | What drove the evolution of color change in chameleons? Chameleons can use color change to camouflage and to signal to other chameleons, but a new paper shows that the need to rapidly signal to other chameleons, and not the need to camouflage from predators, has driven the evolution of this characteristic trait. ...> Full Article |
 | For thousands of years, human beings have relied on commodity barter as an essential aspect of their lives. It is the behavior that allows specialized professions, as one individual gives up some of what he has reaped to exchange with another for something different. In this way, both individuals end up better off. Despite the importance of this behavior, little is known about how barter evolved and developed. ...> Full Article |

 | Aggression, testosterone and nepotism don't necessarily help one climb the social ladder, but the support of a good female can, according to new research on the social habits of an unusual African species of fish. ...> Full Article |
 | Pity the tiny naked mole-rat. The buck-toothed, sausage-like rodent lives by the hundreds in packed, oxygen-starved burrows some six feet under ground. It is even cold-blooded -- which, as far as we know, is unique among mammals. ...> Full Article |
