UCLA life scientists and colleagues have produced one of the first high-resolution genetic maps for African American populations. A genetic map reveals the precise locations across the genome where DNA from a person’s father and mother have been stitched together through a biological process called “recombination.” This process results in new genetic combinations that are then passed on to the person’s children.

The new map will help disease geneticists working to map genetic diseases in African Americans because it provides a more accurate understanding of recombination rates among that population, said the senior author of the research, John Novembre, a UCLA assistant professor of ecology and evolutionary biology and of bioinformatics. The map could help scientists learn the roots of these diseases and discover genes that play a key role in them. (more…)

Where do turtles belong on the evolutionary tree? For decades, the mystery has proven as tough to crack as the creatures’ shells. With their body armor and retractable heads, turtles are such unique creatures that scientists have found it difficult to classify the strange animals in terms of their origins and closest relatives.

*IBM GPFS Storage Technology Scans 10 Billion Files in 43 Minutes*

SAN JOSE, Calif., – 22 Jul 2011: Researchers from IBM today demonstrated the future of large-scale storage systems by successfully scanning 10 billion files on a single system in just 43 minutes, shattering the previous record of one billion files in three hours by a factor of 37.

Growing at unprecedented scales, this advance unifies data environments on a single platform, instead of being distributed across several systems that must be separately managed. It also dramatically reduces and simplifies data management tasks, allowing more information to be stored in the same technology, rather than continuing to buy more and more storage. (more…)

Fossil Reveals Oldest Evidence of Live Birth in Reptiles

A fossil from north-eastern China has revealed that terrestrial reptiles were giving birth to live young at least as early as 120 million years ago

The newly discovered fossil of a pregnant lizard proves that some squamate reptiles (lizards and snakes) were giving birth to live young, rather than laying eggs, in the Early Cretaceous period – much earlier than previously thought. The fossil shows a pregnant female filled with the tiny skeletons of more than 15 baby lizards at a stage of development similar to that of late embryos of modern lizards. The mother lizard, which is 30 centimetres long (excluding her tail), probably died only a few days before giving birth. (more…)
