Yale researchers find environmental toxins disruptive to hearing in mammals
Yale School of Medicine researchers have new data showing chloride ions are critical to hearing in mammals, which builds on previous research showing a chemical used to keep barnacles off boats might disrupt the balance of these ions in ear cells. View More (2006-04-12)
Does missing gene point to nocturnal existence for early mammals?
A gene that makes cells in the eye receptive to light is missing in humans, researchers have discovered. View More (2006-10-13)
Will changes in climate wipe out mammals in Arctic and sub-Arctic areas?
The climate changes depicted by climatologists up to the year 2080 will benefit most mammals that live in northern Europe's Arctic and sub-Arctic land areas today if they are able to reach their new climatic ranges. View More (2013-01-15)
Size of mammals exploded after dinosaur extinction
Researchers demonstrate that the extinction of dinosaurs 65 million years ago made way for mammals to get bigger - about a thousand times bigger than they had been. View More (2010-11-29)
Whales are polite conversationalists
What do a West African drummer and a sperm whale have in common? According to some reports, they can both spot rhythms in the chatter of an ocean crowded with the calls of marine mammals -- a feat impossible for the untrained human ear. View More (2009-10-27)
'Killer' B cells provide new link in the evolution of immunity
Researchers from the University of Pennsylvania School of Veterinary Medicine have discovered a unique evolutionary link between the most primitive innate form of immune defense, which has survived in fish, to the more advanced, adaptive immune response present in humans and other mammals.

Dinosaur extinction didn't cause the rise of present-day mammals, claim researchers
A new, complete 'tree of life' tracing the history of all 4,500 mammals on Earth shows that they did not diversify as a result of the death of the dinosaurs, says new research published in Nature today. View More (2007-03-29)
Size matters: Preventing large mammal extinction
Saving large mammals such as elephants and rhino from extinction could be made more effective by focusing efforts on individual species as well as their habitats. View More (2005-07-25)
Oxygen increase caused mammals to triumph, researchers say
The first, high resolution continuous record of oxygen concentration in the earth's atmosphere shows that a sharp rise in oxygen about 50 million years ago gave mammals the evolutionary boost they needed to dominate the planet. View More (2005-09-30)
Mangrove-dependent animals globally threatened
More than 40 percent of a sample of amphibians, reptiles, mammals, and birds that are restricted to mangrove ecosystems are globally threatened with extinction, according to an assessment published in the July/August issue of BioScience. View More (2009-07-01)
No more squashed hedgehogs?
Wildlife road deaths are preventable according to the results of a survey carried out by The Mammal Society that are released today. Chairman of The Mammal Society, Professor Stephen Harris said "The Mammal Society's National Road Death Survey provides us with the information we need to reduce mammal deaths on roads. It shows that the number of mammal deaths on roads is directly related to... View More (2002-05-29)
More evidence mammals, fruit flies share make-up on function of biological clocks
A study by researchers at New York University and the University of London offers additional evidence that mammals and fruit flies share a common genetic makeup that determines the function of their internal biological clocks. The study appears in the latest issue of Current Biology. View More (2006-03-07)
When animals evolve on islands, size doesn't matter
A theory explaining the evolution of giant rodents, miniature elephants, and even miniature humans on islands has been called into questions by new research published today in Proceedings of the Royal Society B: Biological Sciences. View More (2007-11-07)
Female mammals follow their noses to the right mates
Female birds often choose their mates based on fancy feathers. Female mammals, on the other hand, may be more likely to follow their noses to the right mate. View More (2009-03-18)
Mammals that hibernate or burrow less likely to go extinct
The best way to survive the ill-effects of climate change and pollution may be to simply sleep through it. View More (2009-01-29)
New Explanation for a Puzzling Biological Divide Along the Malay Peninsula
Ecologists at the University of California, San Diego, offer a new explanation for an apparently abrupt switch in the kinds in of mammals found along the Malay Peninsula in southeast Asia - from mainland species to island species - in the absence of any geographical barrier. View More (2009-03-06)
Evolution of genomic imprinting
How we come to express the genes of one parent over the other is now better understood through studying the platypus and marsupial wallaby - and it doesn't seem to have originated in association with sex chromosomes. View More (2007-09-07)
Species distribution models are of only limited value for predicting future mammal distributions
Species distribution models are of only limited use in predicting the future distribution of mammals. This is the finding of a study of the climate niches of 140 indigenous European mammals. View More (2009-12-16)
New Study Shows Effects of Prehistoric Nocturnal Life on Mammalian Vision
Since the age of dinosaurs, most species of day-active mammals have retained the imprint of nocturnal life in their eye structures. Humans and other anthropoid primates, such as monkeys and apes, are the only groups that deviate from this pattern. View More (2012-11-01)
Secret of eternal youth may be in reptiles
Jo'£o Pedro Magalh'£es, researcher in the Biology of Aging, suggests, in work published in the June edition of the magazine "Experimental Gerontology" and entitled "The evolution of mammalian aging", that the study of certain species of reptiles and amphibians that apparently do not age could lead to discoveries about aging. For this Portuguese scientist the secret of eternal youth... View More (2002-06-18)
