Researchers reconstruct parts of the genome of a common mammalian ancestor

...weren't going to be able to do a very good job [of reconstructing the ancestral genome]," said first-author Blanchette, who was a postdoctoral fellow in Haussler's lab when work on the project began. But the research team was able to estimate the accuracy of the reconstruction, using simulations and comparisons acr...

Computer analysis shows scientists could reconstruct the genome of the mammalian common ancestor

Circles of DNA might help predict success of stem cell transplantation

... likely either to fail or be significantly slow in reconstructing the T cell population. "This is the first demonstration that high levels of sjTREC in a potential stem cell recipient can predict that their thymus will successfully reconstitute their T cell population using donated stem cells," said Xiaohua Chen, ...

Scientists find evidence of catastrophic sand avalanches, sea level changes in Gulf of Mexico

Toxins drove evolution of human taste sense, global study reveals

...n 60 human populations from all over the world. By reconstructing the history of the gene, the researchers found evidence of evolutionary selection. Specifically, they found that particular derived variants of the taste receptor rapidly rose to high frequency many thousands of years ago, before the expansion of ear...

Scientists focus on 'dwarf eye'

By reconstructing the woman's family tree, the researchers discovered that several living relatives also suffered from nanophthalmos, and four deceased relatives had been part of the classic Johns Hopkins Bloomberg School of Public Health study in the 1970s that helpe...

New possibilities for flu antiviral and vaccine research emerge from 'Spanish flu' virus

...any of them otherwise healthy adults. By partially reconstructing the Spanish flu virus, researchers have now discovered at least part of what made the virus so lethal, thus providing essential information for influenza drug and vaccine research. The research appears in the 7 October issue of the journal Science, ...

Missing fossil link 'Dallasaurus' found

...mputer simulation. When funds become available for reconstructing a suitable exhibit, the bones of Dallasaurus will be displayed at the Dallas Museum of Natural History. The work, however, will take several more years of additional efforts and substantial funding. A nearly 30-foot long mosasaur, some 75 million yea...

Grant allows ASU archaeologist to study how environment influences evolution

...f the biggest influences that drives evolution, so reconstructing the environment from 400,000 years ago to 30,000 years ago might hold the key to understanding why humans evolved the way they did, Marean said. "During glacial advances throughout the Pleistocene period (an era from 1.6 million years ago to 11,000 y...

Authors, illustrator win AAAS/Subaru SB&F Prize for Excellence in Science Books

New method to analyse the Major Histocompatibility Complex (MHC) of the human genome

...hod to span the entire MHC, but this would require reconstructing the huge complex into several overlapping segments. The new lab method, the researchers noted, could possibly fulfill an unmet need for tools to use in conducting genetic studies in populations of unrelated individuals. The researchers have applied ...

Technique makes it easier to see mouse embryo in all its glory
