One species, many genomes

...l allow the detection of new genes. The plan is to decipher the genomes of at least 1001 Arabidopsis varieties. A new instrument, with which the entire genome of a plant can be read in just a few days, is already available. Still missing are the computational algorithms to interpret the anticipated flood of d...

Gladstone investigators identify a new protective action for the powerful anti-HIV factor, APOBEC3G

... In the current study, the researchers set out to decipher the protein and RNA components of the A3G RNA protein complexes. In so doing, Ya-Lin Chiu, PhD, a postdoctoral fellow in Greene's laboratory, determined that the complexes help to prevent a threat within cells posed by a class of "jumping genes," or ...

LSU professor discovers new species

...tting-edge molecular genetics lab at the LSUMNS to decipher the genetic code of the lizards. "We sequenced the DNA of this new species and several other closely related species in order to help our diagnosis," he said. "Using DNA to help describe new species is becoming one of the most important tools for sci...

Mars mission Risk 29: Scientists research ways to reduce radiation-induced brain damage

... brain's maximum safe cosmic radiation dose and to decipher precisely how radiation causes cognitive impairment, part of a quest for biological countermeasures to reduce radiation-related cognitive impairment. The NASA-funded $14-million research project could not only help eliminate the risks to astronauts...

New technology used to construct the first map of structural variation in the human genome

...ce lies a complex, higher-order code. In order to decipher this level of architecture, scientists have developed powerful new experimental and algorithmic methods to detect copy number variants (CNVs)--defined as large deletions and duplications of DNA segments. These technologies--reported today in the jou...

Study offers innovative profile of enzyme that aids tumor growth

...eir small-molecule metabolite profiles-to begin to decipher the complex metabolic and signaling networks of cancer. According to the study, one of the primary advantages of the functional proteomic technology employed (activity-based protein profiling) is that it can be used to identify inhibitors for unc...

Trotting with emus to walk with dinosaurs

...or a modern analog animal they could study to help decipher the tracks. Large flightless birds are the most logical choice and are, along with all birds today, thought to be descended from dinosaurs. But not all of those alive today are good choices or easy to work with. Ostriches are two-toed and have an...

UCLA researchers develop T-cells from human embryonic stem cells

These results indicate that it is possible to decipher the signals that control the development of embryonic stem cells into mature T-cells, said study co-author Jerome Zack, associate director of the UCLA AIDS Institute, and professor of medicine and of microbiology, immunology and molecular genetics at...

Researchers offer clues to how leaves patterns are formed

...ians and even poets and philosophers have tried to decipher the rules and regulations behind those varied designs and now new research published in part at the University of Alberta offers a big clue to how those patterns are formed. "For years people have been trying to understand this beautiful formation,...

Wild vs. lab rodent comparison supports hygiene hypothesis

Further, bystanders who aim to help - "there are five steps there; it's the third door on the left" - are often wrong, especially people with good vision, Goldring sa...

In a technical tour de force, Salk scientists take a global view of the epigenome

...en sequenced, ENCODE aims to develop technology to decipher what 30 million (1%) of those letters "spell" by identifying not only what genes they encode, but how epigenetic modifications switch genes off and on. Once that's achieved, the effort will be scaled up to learn more about the dynamics of the whole ...

Cracking the genetic code for control of gene expression

... In this post-genomic era, the next big goal is to decipher the genetic code of regulation of gene expression. At the University of Helsinki the researchers have been interested in sequences which regulate gene expression. The research group, led by professor Jussi Taipale, Ph.D, has defined the binding spec...

UC San Diego partners with Venter Institute to build marine microbial genomics cyberinfrastructure

...mputational resource and develop software tools to decipher the genetic code of communities of microbial life in the world's oceans. The new resource will help scientists understand how microbes function in their natural ecosystems, enable studies on the effect humans are having on the environment, as well ...

Poison + water = hydrogen. New microbial genome shows how

...ussia, and other far-flung locales, to isolate and decipher the genomes of microbes found there. "What we want to have is a field guide for these microbes, like those available for birds and mammals," Eisen says. "Right now, we can't even answer simple questions. Do similar hot springs, a world apart, share...

USC researchers track down the stem cells that create feathers

...s the best teacher for tissue engineering. What we decipher from our animal models can then be applied to help human stem cells and adult human organs to regenerate-and regenerate properly." ...

Free-energy theory borne out in large-scale protein folding

...anks to modern genomics, scientists can use DNA to decipher the amino acid sequence in a protein. But knowing the sequence gives no clue to the protein's function, because function is inextricably tied to shape, and every protein self-assembles into its characteristic shape within seconds of being created. "...

University of Arizona plant scientists to unravel maize genome

...me at a fraction of the cost that was necessary to decipher the human genome, which is only slightly larger than the corn genome. "This grant reinforces the position of the UA as a world leader in plantgenomics," said Vicki Chandler, director of BIO5 and a Regents' Professor inthe department of plant scienc...
