Eddy Rubin (left) along with Dario Boffelli led the development of a technique called phylogenetic shadowing which enables scientists to make meaningful comparisons between the genomes of humans and other primates.
In these comparative genomic charts, it is easy to see why meaningful comparisons between humans and other primates have been difficult. The pink areas represent regions of high conservation between the two species being compared, (meaning the sequences are the same in both), the blue areas represent the positions of protein-coding regions and the purple areas represent the non-protein coding parts of a gene.
Scientists with the U.S. Department of Energy’s Joint Genome Institute (JGI) and the Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a powerful new technique for deciphering biological information encoded in the human genome. Called "phylogenetic shadowing," this technique enables scientists to make meaningful comparisons between DNA sequences in the human genome and sequences in the genomes of apes, monkeys, and other non-human primates. With phylogenetic shadowing, scientists can now study biological traits that are unique to members of the primate family.
"Now that the sequence of the human genome has almost been completed the next challenge will be the development of a vocabulary to read and interpret that sequence," says Edward Rubin, M.D., director of the Joint Genome Institute (JGI) for the U.S. Department of Energy, and Berkeley Lab’s Genomics Division, who led the development of the phylogenetic shadowing technique.
"The ability to compare DNA sequences in the human genome to sequences in non-human primates will enable us in some ways to better understand ourselves than the study of evolutionarily far-distant relatives such as the mouse or the rat," Rubin adds. "This is important because as valuable as models like the mouse have been, there are many physical and biochemical attributes of humans that only other primates share."

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.
Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...
Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.
Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.
Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.
After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.
"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
