Mittermeier, who chairs the Primate Specialist Group of IUCN-The World Conservation Union's Species Survival Commission. ``A large, striking monkey in a country of considerable wildlife resear...

Can our genes tell the story of our divergence?

...from understanding why we're so different from our closest primate cousins, but this study provides plenty of tools, and hypotheses, to mine the tiny differences in our DNA for more clues. ### Citation: Nielsen R, Bustamante C, Clark AG, Glanowski S, Sackton TB, et al. (2005) A scan for positively selected...

'Jumping genes' contribute to the uniqueness of individual brains

..., and the immune system's diversity is perhaps the closest analogy we have," says Gage. In the immune system, the genes coding for antibodies are shuffled to create a wide variety of antibodies capable of recognizing an infinite number of distinct antigens. In their study, the researchers closely tracked a...

Hopkins scientists uncover 'tags' that force proteins to cell surface

...sine, in that order. "This particular tag and its closest relatives actually mark normal proteins for delivery to the cell surface," says Li. "In some diseases, a protein that should be on the cell surface isn't, and in the lab, sometimes it's proven impossible to get a protein to the cell surface in order ...

"This is very creative, painstaking epidemiology," said Jerrold L. Abraham, professor and director of environmental and occupational pathology at SUNY Upstate Medica...

Human cerebellum and cortex age in very different ways

... age so differently from our own suggests that our closest evolutionary relatives may use their brains very differently than we do," Plotkin says. "It appears that genome-wide patterns of aging evolve very rapidly." The scientists say their results may cast some doubt on the effectiveness of mice and other ...

Tsunami + 1 year: Reviving exhausted fisheries should trump replacing boats, gear, experts say

...lable fish. In addition to Indonesia, the country closest to the underwater earthquake epicenter, the tsunami disrupted lives in many countries, including Thailand, India, Maldives and Sri Lanka. Officials estimate the total repair cost throughout the affected area at $5.8 billion, while a total of $4.4 b...

Ancient trans-Atlantic swarm brought locusts to the New World

...ve answered a long-standing conundrum: why are the closest relatives of the African desert locust (Schistocerca gregaria) found in the New World, rather than Africa? The desert locust is one of the world's most economically important insects, and is capable of forming massive swarms that devastate crops. DN...

Older female fish prefer imperfect male mates, study finds

...Morris said. "Therefore, any fish they see that is closest to this prototype is preferred." The same phenomenon has been suggested to explain attraction in other animals, including humans. As their lives progress, however, female swordtails may encounter more asymmetrical than symmetrical males, and so beg...

Health of Acehnese reefs in the wake of the tsunami shows human impacts more harmful

... in Current Biology, tsunami damage to coral reefs closest to the epicenter of the 2004 Sumatra-Andaman earthquake was occasionally spectacular, but surprisingly limited, particularly when compared to damage from chronic human misuse in the region. Less than 100 days after the tsunami of December 26, 2004,...

Understanding the oceans microbes is key to the Earth's future

Canine cancer vaccine program shows early promise

...tage of dogs with melanoma will respond. "It's the closest thing to a miracle I've ever seen," says Maggie Hoefling, of Largo, Florida. Following vaccine therapy, her husband Gus's 14-year-old beagle, Mack, not only lived an additional two years, but thrived. And that's after their local veterinarian gave ...

Birds that make teeth

The findings strongly suggest that the birds were initiating developmental programs similar to those of their reptilian ancestors. In addition, the authors found that the capacity to form teeth still resides in norm...
