New species from old data

In a new study, researchers present a “cautionary tale?about what may go wrong when using the fledgling science of proteomics to devise a diagnostic test for cancer. In the February 16 issue of the Journal of the National Cancer Institute, researchers from The University of Texas M. D. Anderson Cancer Center detail why an experimental test intended to identify early ovarian cancer from a...

New Clues Add 40,000 Years to Age of Human Species

Nearly 40 years after an historic anthropology expedition to Ethiopia's Lake Turkana basin, researchers have uncovered evidence suggesting human bones found at that time are roughly 195,000 years old. The researchers believe the findings may bolster the “Out-of-Africa?hypothesis that suggests we all trace to an ancient line that first evolved in Africa and then displaced other hominids as recent...

Ants Genetic Engineering Leads To Species Interdependency

Findings reported last week reveal how anevolutionary innovation involving the sharing of genes between two antspecies has given rise to a deep-seated dependency between them for thesurvival of both species populations.The new work illustrates how genetic exchange through interbreedingbetween two species can give rise to a system of interdependence at ahigh level of biological organization...

Same mutation aided evolution in many fish species, Stanford study finds

After decades of laboratory work studying how animals evolve, researchers sometimes need to put on the hip waders, pull out the fishing net and go learn how their theory compares to the real world. According to a Stanford University School of Medicine study published in the March 25 issue of Science, Mother Nature is more predictable than lab experiments suggest. In a diverse group of fish...

Fibril Shape Is The Basis Of Prion Strains And Cross-species Prion Infection

New research on prions, the infectious proteins behind "mad cow" disease and Creutzfeld-Jakob disease in humans, suggests that the ability of prions in one species to infect other species depends on the shape of the toxic threadlike fibers produced by the prion. Two studies on the topic appear in the 8 April issue of the journal Cell. Although research suggests that prions from one specie...
