Which came first, the chicken genome or the egg genome?
Which came first, the chicken genome or the egg genome? Researchers have answered a similarly vexing (and far more relevant) genomic question: Which of the thousands of long stretches of repeated DNA in the human genome came first? And which are the duplicates? view more (2007-10-09)
First genome-wide study of infectious disease opens new avenues for HIV treatment, vaccines
The first genome-wide association study of an infectious disease, conducted by an international group of researchers through the Center for HIV/AIDS Vaccine Immunology (CHAVI), has yielded a new understanding of why some people can suppress virus levels following HIV infection. view more (2007-07-23)
An ancient protein balances gene activity and silences foreign DNA in bacteria
Compared to humans, bacteria have a much tidier genome. The tiny microorganisms pack their genes closely together, and don't carry around a lot of extraneous DNA, so-called junk DNA that fills in the gaps between genes. view more (2008-05-16)
UNC medical geneticist cautions against rushing into genetic testing
Just because scientific advances now allow individuals to learn their genetic make-up doesn't mean they should rush into genetic testing in hopes of making revolutionary improvements to their health, cautions a geneticist and practicing physician at the University of North Carolina at Chapel Hill. view more (2008-06-02)
Life Cycle of Operons Yields New Look at Bacterial Genetics
In a breakthrough that will immediately benefit biologists who study bacteria, and could in the future have bearing on the advancement of synthetic biology, a team of researchers has determined the life cycle of operons, small groups of genes with related functions that are co-transcribed in a single strand of messenger RNA. view more (2006-07-06)
Genome duplication responsible for more plant species than previously thought
Extra genomes appear, on average, to offer no benefit or disadvantage to plants, but still play a key role in the origin of new species, say scientists from Indiana University Bloomington and three other institutions in this week's Proceedings of the National Academy of Sciences. view more (2009-08-13)
Cancer cells need normal, nonmutated genes to survive
Corrupt lifestyles and vices go hand in hand; each feeds the other. But even the worst miscreant needs customary societal amenities to get by. view more (2009-05-29)
Evolving complexity out of 'junk DNA'
The study, published today in Proceedings of the National Academy of Sciences, USA, claims to have solved this scientific riddle by analysing the genomics of primitive living fishes such as sharks and lampreys and their spineless relatives, such as the sea squirts. view more (2008-02-12)
NYU scientists begin second phase of project to better understand disease
A team of researchers at New York University's Center for Comparative Functional Genomics are embarking on the second phase of a collaborative research undertaking to predict structures of key proteins, which in turn shed light on their roles in diseases and offer pathways for cures. view more (2006-06-28)
Africa's rarest monkey had an intriguing sexual past, DNA study confirms
The most extensive DNA study to-date of Africa's rarest monkey reveals that the species had an intriguing sexual past. Of the last two remaining populations of the recently discovered kipunji, one population shows evidence of past mating with baboons while the other does not. view more (2009-11-12)
New study of gene evolution could lead to better understanding of neurodegenerative disease
Genetic evolution is strongly shaped by genes' efforts to prevent or tolerate errors in the production of proteins, scientists at The University of Texas at Austin and Harvard University have found. view more (2008-07-25)
Minuscule molecules pack a powerful punch
A role for a microRNA in the immune system has been shown by study of one of the world's first microRNA knockout mouse, reported Friday 27 April in Science. view more (2007-04-27)
Genomes of more than 200 human flu strains reveal a dynamic virus
In the first large-scale effort of its kind, researchers have determined the full genetic sequence of more than 200 distinct strains of human influenza virus. view more (2005-10-06)
Genes from tiny marine algae suggest unsuspected avenues for new research
By sequencing the DNA of two tiny marine algae, a team of scientists has opened up a myriad of possibilities for new research in algal physiology, plant biology, and marine ecology. view more (2009-04-10)
Decoded sea urchin genome shows surprising relationship to humans
The Sea Urchin Genome Sequencing Project (SUGSP) Consortium, led by the Human Genome Sequencing Center at Baylor College of Medicine (BCM-HGSC) in Houston, announced today the decoding and analysis of the genome sequence of the sea urchin, Strongylocentrotus purpuratus. view more (2006-11-10)
Chicken genome gives insights into human genome
The draft sequence of the wild chicken, Gallus gallus, will be published in the Dec 9th issue of Nature (cover story). The analysis of this genome is not about getting bigger eggs and tastier chicken - it's giving scientists surprising insights into the human genome. Researchers can use these new data as a tool to identify similar sequences in... view more... (2004-12-06)
The Ethics of Patenting DNA and Proteins
Many companies and universities throughout the world are seeking to file patents on gene sequences and proteins. Questions remain, however, over the moral implications of protecting rights to property in this kind of way. The Nuffield Council on Bioethics is holding a series of Roundtable meetings to consider the ethical and legal issues raised by... view more... (2000-09-06)
Gene discovered for type 1 diabetes in children
Pediatrics researchers at The Children's Hospital of Philadelphia and McGill University in Montreal have identified a gene variant that raises a child's risk for type 1 diabetes, formerly called juvenile diabetes. view more (2007-07-16)
Evidence that up to 10 percent of human genome may have changed very recently revealed by CU researchers
A Cornell study of genome sequences in African-Americans, European-Americans and Chinese suggests that natural selection has caused as much as 10 percent of the human genome to change in some populations in the last 15,000 to 100,000 years, when people began migrating from Africa. view more (2007-07-12)
Mutant sperm guide clinicians to new diseases
Research published today in Nature Genetics shows that some rearrangements of the human genome occur more frequently than previously thought. view more (2007-12-03)
