Researcher razzle-dazzle

By | May 28, 2009

Biomedical researchers don't typically rub elbows with rock-'n-roll royalty in the pages of glossy magazines. In fact, they never do. Until now.

Ancient organism, modern immunity

By | May 27, 2009

The adaptive immune system, which can recognize, attack, and remember potentially harmful microbes, may have appeared on the evolutionary scene millions of years earlier than scientists thought. The immune system of the sea lamprey, a primitive, jawless fish, contains two cell types that recognize and respond to characteristic molecules associated with invading pathogens, researchers report in this week's __Nature__. "It's amazing to us," lead author linkurl:Max Cooper,;http://www.gra.org/Emine

Going against the group

By | May 27, 2009

A new theoretical model of parasite virulence linkurl:published;http://www.nature.com/nature/journal/vaop/ncurrent/full/nature08071.html in this week's __Nature__ puts a chink in the armor of group selection theory, the idea that organisms act altruistically for the betterment of groups as a whole.

Immunity can be lymph-less

By | May 27, 2009

Researchers have overturned the long-standing notion that lymph nodes are always necessary for launching the mammalian immune response. Fluorescently-labeled mouse liver Image: Burkhard Becher According to a linkurl:study;http://www.plosbiology.org/article/info%3Adoi%2F10.1371%2Fjournal.pbio.1000109 published in this month's issue of PLoS Biology, in the absence of lymph nodes, cell-mediated immunity can be activated in the liver. The findings undercut immunology "dogma," which says the immun

Transgenic primates transmit DNA

By | May 27, 2009

Japanese researchers have successfully generated the world's first transgenic primates capable of passing on a foreign gene to their offspring. The feat, linkurl:reported;http://www.nature.com/nature/journal/v459/n7246/abs/nature08090.html in tomorrow's (May 28) issue of __Nature__, should pave the way for more sophisticated models of human disease, though the monkey models still have many hurdles to overcome.

New tool for African genomics

By | May 24, 2009

Genome-wide association studies (GWAS) in Africa are not as straightforward as such research among populations of people of European or Asian ancestry, because African populations are much more genetically diverse. But researchers studying malaria resistance in western Africa say they've found a way to make African GWAS work. An international team of researchers report in this week's issue of __Nature Genetics__ that it's possible to perform genome-wide studies to probe for genes behind disease

Video: The oceans of old

By | May 24, 2009

In the distant past giant cod (1.5 meters long) ruled the North Sea. Southern oceans boiled with massive pods of right whales. Gangs of 4-meter-long porpoises cavorted off the British Isles. These are but a few of the surprises turned up by an international team of marine researchers who scoured old ship logs, fishbone-littered middens, Latin and Greek verse, tax accounts, dusty legal documents, and even mounted trophies to paint a picture of oceans past. Marine scientists compiled the data as
