 | Like many northerners who head south to warmer climates for the winter, many Northern right whales also head south in November and stay into April. Their destination is the only known calving ground for this rare and endangered population-the waters off Florida, Georgia and South Carolina. When they arrive, NOAA scientists are there to greet them, and to take DNA samples. ...> Full Article |
 | Rats use their whiskers in a way that is closely related to the human sense of touch: Just as humans move their fingertips across a surface to perceive shapes and textures, rats twitch their whiskers to achieve the same goal. Now, in a finding that could help further understanding of perception across species, MIT neuroscientists have used high-speed video to reveal rat whiskers in action and show the tiny movements that underlie the rat's perception of its tactile environment. ...> Full Article |
 | Researchers have known for awhile that little whirlpools of air stirred up by insects' wing motions can help keep these small organisms aloft as they fly slowly or hover, two activities essential for food foraging. But how a weightier organism-a bat-manages to stay aloft during slow flight has remained unclear. ...> 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.

 | 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 |

 | Wildebeest Whether you are dealing with the number of wildebeest on the Serengeti or the number of malaria parasites in the human body, new research shows the same ecological framework determines breeding numbers and population size. New research published today (15 January) in Proceedings of the National Academy of Sciences by a Biotechnology and Biological Sciences Research Council (BBSRC) Fellow shows that the same community ecology principles that determine how different animal species on the savannah affect each other's population sizes through competition for food and hunting by predators also affect parasite species interacting within the microcosm of a single host. ...> Full Article |

 | When resources are scarce, who you know and where you're positioned on the social totem pole affects how far you'll go to search for food. At least that's the case with African elephants, according to a study led by ecologists at the University of California, Berkeley, who collaborated with researchers at Save the Elephants, a non-profit research organization based in Kenya, and at the University of Oxford in England. ...> Full Article |
