Extreme Genomic Evolution Discovered In Burmese Pythons
2013-12-03 07:05:43

[ Watch the Video: Genomics Reveal The Evolution Of Snakes ] April Flowers for redOrbit.com - Your Universe Online A team of researchers have sequenced the genome of the Burmese python, or Python molurus bivittatus, finding large numbers of rapidly evolved genes in snakes. Their findings, published in Proceedings of the National Academy of Sciences (PNAS), reveal that these genetic changes are linked to extreme characteristics in snakes. The discovery of these characteristics,...

A new view of our chromosomes reveals a complex picture Chromosomes – the 46 tightly-wrapped packages of genetic material in our cells – are iconically depicted as X-shaped formations. However, those neat X’s only appear when a cell is about to divide and the entire contents of its genome duplicated. Until now researchers have not been able to get a good picture of the way that our DNA – some two meters of strands all told – is neatly bundled into the nucleus while enabling...

In a collaborative study, researchers from Lanzhou University, BGI and other institutes have succeeded in unraveling the whole genome sequence of desert poplar, Populus euphratica, and the genetic bases underlying poplar to against salt stress. This work provides new insights for understanding the genetic basis of tree adaptation to salt stress and facilitating the genetic breeding of cultivated poplars for saline fields. The research results have been published online in Nature...

An original model that would explain how regions of the genome that are copied later on facilitate the birth of new genes with specific functions in tissues and organs One of the most important processes in the life of cells is genome replication, which consists of making exact copies of the DNA in order to pass it on to their offspring when they split. In most organisms, from yeast to human beings, genome replication follows a set plan, in which certain regions of the genome replicate...

New studies show life events influence genes important for memory and drug use New human and animal research released today demonstrates how experiences impact genes that influence behavior and health. Today's studies, presented at Neuroscience 2013, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health, provide new insights into how experience might produce long-term brain changes in behaviors like drug addiction...

Gladstone-led study reveals new insight into origins of our species What does it mean to be human? According to scientists the key lies, ultimately, in the billions of lines of genetic code that comprise the human genome. The problem, however, has been deciphering that code. But now, researchers at the Gladstone Institutes have discovered how the activation of specific stretches of DNA control the development of uniquely human characteristics—and tell an intriguing story about the...

Most Complete Genome Sequences Generated From Single E. coli Cells And Individual Neurons From The Human Brain
2013-11-11 08:40:04

University of California - San Diego Researchers led by bioengineers at the University of California, San Diego have generated the most complete genome sequences from single E. coli cells and individual neurons from the human brain. The breakthrough comes from a new single-cell genome sequencing technique that confines genome amplification to fluid-filled wells with a volume of just 12 nanoliters. The study is published in the journal Nature Biotechnology on November 10, 2013. "Our...

Deleting One Gene In Fungus Reveals New Compounds With Antibiotic Potential
2013-11-01 08:42:09

Oregon State University Researchers at Oregon State University have discovered that one gene in a common fungus acts as a master regulator, and deleting it has opened access to a wealth of new compounds that have never before been studied – with the potential to identify new antibiotics. The finding was announced today in the journal PLOS Genetics, in research supported by the National Institutes of Health and the American Cancer Society. Scientists succeeded in flipping a genetic...
