Research finds that circadian rhythms dominate all life functions
... in 98 to 99 percent of all genes through advanced computer
algorithms. Most of these genes have never been previously reported as changing their expression level in a daily cycle. Some of these genes, considered "housekeeping," have been used as a stable reference platform in gene expression studies. "Any...
Exploring the dark matter of the genome
...Francisco State University. "We used a pipeline of computer
programs to analyze the raw sequence data, in search of genes. We identified patterns of codons that might indicate a gene splice-site or a promoter, for example. We mapped experimentally derived evidence of messenger RNAs back to the matching hetero...
University of Washington researchers play leading role in major study of human genome function
...ble, UW associate professor of genome sciences and computer
science. Together, they created new computational techniques and used powerful computers to unravel the locations of gene-controlling sequences, and to pull together data generated by other ENCODE centers to gain a more complete picture of how the ge...

Largest synthetic gene ever built offers insights into anti-malarial drug resistance
...hen "back translated" the protein sequence using a computer
program to change the parasite gene sequence − which combines nucleotide base pairs in a way that is found in no other life form − into one that could be "read" by yeast. The yeast are then able to produce the PfMDR1 protein, in its proper sequence, ...
Envisat captures first image of Sargassum from space
...inciple behind Grid computing is that anything one computer
can do, a pool of computers can do faster and better, enabling the solution of massively complex tasks beyond the capabilities of a single machine or local network. By using Grid technology, Gower and King intend to compute 5-years worth of MERIS ...
Washington University in St. Louis to invest $55 million for renewable energy research

Simulations unravel outer membrane transport mechanism
Using X-ray data and advanced computer
simulation and visualization software, researchers at the University of Illinois have painstakingly modeled a critical part of a mechanism by which bacteria take up large molecules. Their findings provide a rare window on the complex interplay of pro...
What's going on in the body? Advanced time-of-flight PET takes a superior 'look'
WASHINGTON, D.C.Moving from computer
