No new neurons in the human olfactory bulb
Research from Karolinska Institutet shows that the human olfactory bulb - a structure in the brain that processes sensory input from the nose - differs from that of other mammals in that no new neurons are formed in this area after birth. View More (2012-05-24)
Nearly one-tenth of hemisphere's mammals unlikely to outrun climate change
A safe haven could be out of reach for 9 percent of the Western Hemisphere's mammals, and as much as 40 percent in certain regions, because the animals just won't move swiftly enough to outpace climate change. View More (2012-05-15)
Healthcare for the US Navy's animal warriors could help people stay healthier
Military patrol dogs with your keen sense of smell, step aside. The U.S. Navy has enlisted the biological sonar and other abilities of bottlenose dolphins and California sea lions to protect harbors from enemy swimmers, detect explosives on the seafloor and perform other tasks.

NOAA discovers way to detect low-level exposure to seafood toxin in marine animals
NOAA scientists and their colleagues have discovered a biological marker in the blood of laboratory zebrafish and marine mammals that shows when they have been repeatedly exposed to low levels of domoic acid, which is potentially toxic at high levels. View More (2012-05-07)

Study reveals how cancer drug causes diabetic-like state
Scientists at Dana-Farber Cancer Institute have discovered why diabetic-like symptoms develop in some patients given rapamycin, an immune-suppressant drug that also has shown anti-cancer activity and may even slow ageing. View More (2012-04-04)
Study suggests why some animals live longer

Increase in Arctic shipping poses risk to marine mammals
A rapid increase in shipping in the formerly ice-choked waterways of the Arctic poses a significant increase in risk to the region's marine mammals and the local communities that rely on them for food security and cultural identity, according to an Alaska Native groups and the Wildlife Conservation Society who convened at a recent workshop.

Baboon-like social structure creates efficiencies for spotted hyena
As large, carnivorous mammals, spotted hyenas are well known for their competitive nature; however, recent work suggests that their clan structure has similarities to some primate social systems such as those of the baboon and macaque. View More (2012-03-14)
From mouse to man: Circadian nitrogen balance impacts survival and susceptibility to common diseases
Researchers at Case Western Reserve University School of Medicine demonstrated that nitrogen balance, the process of utilizing amino acids and disposing of their toxic byproducts, occurs with a precise 24-hour rhythm - also known as circadian rhythm - in mammals. View More (2012-03-07)
UF scientists name new ancient camels from Panama Canal excavation
The discovery of two new extinct camel species by University of Florida scientists sheds new light on the history of the tropics, a region containing more than half the world's biodiversity and some of its most important ecosystems. View More (2012-03-01)

Preserved habitat near national parks helps species conservation
National parks often are established to help preserve species native to a particular region, but it appears that some species preservation is more successful if a significant portion of land adjacent to a park also is left as natural habitat. View More (2012-01-31)
What do killer whales eat in the Arctic?
Killer whales (Orcinus orca) are the top marine predator, wherever they are found, and seem to eat everything from schools of small fish to large baleen whales, over twice their own size. View More (2012-01-30)
