Animal magnetism provides a sense of direction
They may not be on most people's list of most attractive species, but bats definitely have animal magnetism. Researchers from the Universities of Leeds and Princeton have discovered that bats use a magnetic substance in their body called magnetite as an 'internal compass' to help them navigate. View News Article (2008-02-27)


Long life and resistant to diseases? Our money's on bats to survive the apocalypse
Bats are amazing creatures. They've been around for at least 65 million years, and in that time have become one of the most abundant and widespread mammals on earth. View News Article (2012-12-21)


After dinosaurs, mammals rise but their genomes get smaller
Evidence buried in the chromosomes of animals and plants strongly suggests only one group -- mammals -- have seen their genomes shrink after the dinosaurs' extinction. View News Article (2009-07-28)


U of S-led team unlocks link between sex and the female brain
An international team of scientists led by Gregg Adams at the University of Saskatchewan has discovered that a protein in semen acts on the female brain to prompt ovulation, and is the same molecule that regulates the growth, maintenance, and survival of nerve cells. View News Article (2012-08-21)


New American Chemical Society video explains why cats lack a sweet tooth
Do cats purrr-ferrr sardines or sweets? The American Chemical Society (ACS), the world's largest scientific society, today released a new Bytesize Science video that explains why cats, unlike humans and other mammals, are indifferent to sweet flavors. View News Article (2013-03-05)


When every photon counts
The eyes of nocturnal mammals have very large numbers of highly-sensitive rod photoreceptors (the cell type responsible for night vision). They have to perceive light which is less than a millionth of the intensity of daylight. View News Article (2009-04-17)


Our brains are more like birds' than we thought
For more than a century, neuroscientists believed that the brains of humans and other mammals differed from the brains of other animals, such as birds (and so were presumably better). This belief was based, in part, upon the readily evident physical structure of the neocortex, the region of the brain responsible for complex cognitive behaviors. View News Article (2010-07-06)


Field Museum provides gold standard for mammal survey

CNIO team discovers the first real indicator of longevity in mammals
A team of researchers from the Spanish National Cancer Research Centre (CNIO), headed by CNIO Director María Blasco, has demonstrated in a pioneering study on mammals that longevity is defined at a molecular level by the length of telomeres.  View News Article (2012-09-28)


Climate caused biodiversity booms and busts in ancient plants and mammals
A period of global warming from 53 million to 47 million years ago strongly influenced plants and animals, spurring a biodiversity boom in western North America, researchers from three research museums report in a paper published online this week in the Proceedings of the National Academy of Sciences. View News Article (2009-08-07)
