Evolution study tightens human-chimp connection
Scientists at the Georgia Institute of Technology have found genetic evidence that seems to support a controversial hypothesis that humans and chimpanzees may be more closely related to each other than chimps are to the other two species of great apes - gorillas and orangutans. view more (2006-01-24)
Hopkins scientists ID 10 genes associated with a risk factor for sudden cardiac death
One minute, he's a strapping 40-year-old with an enviable cholesterol level, working out on his treadmill. view more (2009-03-23)
Studies highlight MRSA evolution and resilience
Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections are caused primarily by a single strain-USA300-of an evolving bacterium that has spread with "extraordinary transmissibility" throughout the United States during the past five years, according to a new study led by National Institutes of Health (NIH)... view more...

Researchers publish first marsupial genome sequence
An international team, led by researchers at the Broad Institute of MIT and Harvard, and supported by the National Institutes of Health (NIH), today announced the publication of the first genome of a marsupial, belonging to a South American species of opossum. view more (2007-05-10)
Genome circularization and RNA virus replication
As featured on the cover of the August 15th issue of G&D, an Argentinian research team, led by Dr. Andrea Gamarnik, report on their recent discovery of a novel mechanism of dengue virus replication. view more (2006-08-01)
St. Jude identifies genomic causes of a certain type of leukemia relapse
Scientists at St. Jude Children's Research Hospital have identified distinctive genetic changes in the cancer cells of children with acute lymphoblastic leukemia (ALL) that cause relapse. The finding offers a pathway to designing treatments for ALL relapse in children and, ultimately, in adults. view more (2008-12-01)
Scientists uncover new genetic variations linked to psoriasis
Two international teams of researchers have made significant gains in understanding the genetic basis of psoriasis, a chronic skin condition that can be debilitating in some patients. Their research, involving thousands of patients, is reported in two studies published this week in the advance online Nature Genetics. view more (2009-01-27)
UI biologist studies ocean plant cell adaptation in climate change
How will plant cells that live in the oceans and serve as the basic food supply for many of the world's sea creatures react to climate change? view more (2009-04-16)
Bioinformatics sheds light on evolutionary origin of Rickettsia virulence genes
Scientists from the Virginia Bioinformatics Institute (VBI) at Virginia Tech, the University of Maryland School of Medicine, and the University of Louisville have revealed that genes for a specific type of molecular secretion system in Rickettsia, a structure that is linked in many cases to virulence, have been conserved over many years of... view more...

Brown-led study rearranges some branches on animal tree of life
A study led by Brown University biologist Casey Dunn uses new genomics tools to answer old questions about animal evolution. The study is the most comprehensive animal phylogenomic research project to date, involving 40 million base pairs of new DNA data taken from 29 animal species. view more (2008-03-06)
Gut reaction: Researchers define the colon's genome
For the first time, scientists have defined the collective genome of the human gut, or colon. Up to 100 trillion microbes, representing more than 1,000 species, make up a motley "microbiome" that allows humans to digest much of what we eat, including some vitamins, sugars, and fiber. view more (2006-06-02)
Mapping the foundation of human development
Embryonic stem cells may one day provide a means to treat disease, but according to two new reports, they are already revealing remarkable insights into the mysteries of human biology. view more (2006-04-21)
Novel experiment documents evolution of genome in near-real time
A team led by bioengineering researchers at UC San Diego report in the November issue of Nature Genetics rapid evolutionary changes in a bacterial genome, observed in near-real time over a few days. view more (2006-11-06)
Sequences reveal benign origin of deadly plant pathogens
An international team of researchers has published the draft genome sequences of two deadly plant pathogens, Phytophthora ramorum and Phytophthora sojae. view more (2006-09-01)
New risk variant for atopic dermatitis identified
Scientists of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch and Charité - University Medical School, Berlin, Germany, in collaboration with researchers from the Klinikum rechts der Isar of Technical University Munich and Christian Albrecht University, Kiel, have identified a gene variant on chromosome 11 that is... view more...

New genetic analysis forces re-draw of insect family tree
The family tree covering almost half the animal species on the planet has been re-drawn following a genetic analysis which has revealed new relationships between four major groups of insects. view more (2006-10-27)
Flu virus trots globe during off season
The influenza A virus does not lie dormant during summer but migrates globally and mixes with other viral strains before returning to the Northern Hemisphere as a genetically different virus, according to biologists who say the finding settles a key debate on what the virus does during the summer off season when it is not infecting people. view more (2007-09-21)
Evolutionary origin of bacterial chromosomes revealed
Researchers have unveiled the evolutionary origin of the different chromosomal architectures found in three species of Agrobacterium. view more (2009-03-27)
CSHL researchers map changing epigenetic modifications that enable transposons to run amok
Much like cancer cells, plant cells grown for a long time outside of their normal milieu, in culture dishes, have highly unstable genomes. view more (2008-12-11)
Parasites ready to jump
Transposons are mobile genetic elements found in the hereditary material of humans and other organisms. They can replicate and the new copies can insert at novel sites in the genome. view more (2009-08-03)
