...program director of the General Clinical Research Center at Beth Israel, where he studied mechanisms of acute renal failure. He also conducted research at Mount Desert Island Biological Laboratory in Maine, focusing most recently on the cellular transport of salt in a shark model of the ascending limb of mammalian kidneys. He worked in the Desert Island lab for 40 years and served as its president for 10 years. As a research mentor in Maine, Epstein worked with high school and medical school students exploring marine physiology. Michael Amato, a freshman at the University of North Caroline, Chapel Hill, worked...
...data from more than 1,700 experts in 130 countries, the five-year collaborative study tracked habitats, distributions and threats to every known species of mammal on the planet. That isn't as straightforward as you might think. New species are discovered constantly - the total number of known mammalian species is up 19% since 1992. Though they're the largest type of animals, mammals range in size from the titanic blue whale to the tiny mouse lemurs of Madagascar, which can fit in the palm of your hand. What they have in common are clear threats from us. "Mammals...
INDIE HITS Want a hot idea for a popular rock song? How about one that deals with mammalian metabolism? No? What about particle physics or James K. Polk? Such improbable topics have made They Might Be Giants a phenomenon in the indie-rock world for more than 20 years--and that same sense of curiosity and ingenuousness is now making them just as popular with kids...
...reflex that will cause your breathing muscles - including the diaphragm and the muscles between the ribs - to spasm. The pain of these spasms is what causes most people to gulp for breath after just a couple of minutes. When holding your breath underwater, however, you have a bit of mammalian evolution on your side. When humans are submerged in cold water, our bodies instinctively prepare to conserve oxygen, much in the way that dolphins' and whales' bodies do when they dive. "Heart rate drops, blood pressure goes up and circulation gets redistributed," Potkin says. The body's focus becomes getting...
...thing that draws a human male to a child of his is that, hormonally speaking, men are a lot more similar to women than many of us realize, particularly during the critical survival period approaching a child's birth and its infancy. As in some other mammalian species, human males are known to have high levels of prolactin (a hormone usually associated with lactating mothers) toward the end of a partner's pregnancy...
