Genetic differences between yeasts greater than those between humans and chimpanzees
The mapping of the entire yeast genome in 1996 marked the beginning of a revolution in biological and medical research. The human genome was mapped in 2001, and by now the number of characterised species is approaching 1000, most of which are bacteria. view more (2009-02-13)
Fruit flies unlock Methuselah's secrets
New research published in Genome Biology investigates genes that increase the life span of fruit flies in an effort to gain a greater understanding of the ageing process. The researchers from the University of Southern California and Harvard Medical School screened 10,000 fruit fly populations that were mutated. Their results revealed that six... view more...

Tool Helps Identify Gene Function in Soybeans, Could Lead to Better Crop Performance, say MU Researchers
In the race for bioengineered crops, sequencing the genome could be considered the first leg in a multi-leg relay. view more (2008-12-02)
Scaled-down genome may power up E. coli's ability in lab, industry
By stripping the E. coli genome of vast tracts of its genetic material-hundreds of apparently inconsequential genes-a team of Wisconsin researchers has created a leaner and meaner version of the bacterium that is a workhorse of modern biology and industry. view more (2006-04-28)
Genotyping takes us closer to an osteoporosis fingerprint
For the first time ever, an extensive genome-wide search has been undertaken to find the genes linked to osteoporosis and fracture. Five regions of interest have been identified that appear to warrant further scientific investigation. view more (2008-04-30)
Supersized 'island' of resistance genes discovered in an infectious bacterium
Researchers have discovered a cluster of 45 genes coding for antibacterial drug resistance in the bacterium, Acinetobacter baumannii, a major cause of hospital-acquired infections worldwide. view more (2006-01-13)
Creating a new approach to archiving human genetic information
A genome sequence is a long sequence written in a four letter code-3 billion letters in the case of a human genome. But what is the meaning-how is the code deciphered? view more (2008-07-08)
Identifying cancer genes - will it really lead to better treatment?
Copenhagen, Denmark: A systematic trawl through the human genome looking for the abnormalities that drive cancer is already producing promising results, a scientist told ECCO 12 - The European Cancer Conference in Copenhagen today (Tuesday 23 September). Dr. Michael Stratton, Director of the Cancer Genome Project at the Wellcome Trust Sanger... view more... (2003-09-21)
CSHL scientists discover how 'companion' cells to sperm protect them from genetic damage
In plant pollen grains, sperm cells, which carry the genetic material to be passed on to progeny, are cocooned within larger "companion" cells that are called pollen vegetative cells. These companions provide sperm with energy and nourishment, and push them towards their targets during fertilization. view more (2009-02-06)
UA researchers find smallest cellular genome
The smallest collection of genes ever found for a cellular organism comes from tiny symbiotic bacteria that live inside special cells inside a small insect. view more (2006-10-13)
Chimpanzee study reveals genome variation hotspots
Researchers believe that dynamic regions of the human genome - "hotspots" in terms of duplications and deletions - are potentially involved in the rapid evolution of morphological and behavioral characteristics that are genetically determined. view more (2006-05-16)
Microbe has huge role in ocean life, carbon cycle
Researchers at Oregon State University and Diversa Corporation have discovered that the smallest free-living cell known also has the smallest genome, or genetic structure, of any independent cell-and yet it dominates life in the oceans, thrives where most other cells would die, and plays a huge role in the cycling of carbon on Earth. view more (2005-08-19)
Rhythmic genomics -- the yeast metronome and the walk of life
New genome sequence information from the humble baker's yeast has revealed surprising variation in a set of genes that can be thought of as nature's oldest clock. view more (2009-04-08)
'Junk' DNA proves functional
In a paper published in Genome Research on Nov. 4, scientists at the Genome Institute of Singapore (GIS) report that what was previously believed to be "junk" DNA is one of the important ingredients distinguishing humans from other species. view more (2008-11-05)
Emory scientists develop new map of genetic variation in human genome
Emory University scientists have identified and created a map of more than 400,000 insertions and deletions (INDELs) in the human genome that signal a little-explored type of genetic difference among individuals. view more (2006-08-11)
Scientists to assess effects of multiple copies of genes on disease risk
Scientists at Washington University School of Medicine in St. Louis and the biotech firm Nimblegen Systems Inc. have successfully tested a technique for identifying newly recognized DNA variations that may influence disease risk. view more (2007-01-31)
Sea urchin genome suprisingly similar to man and may hold key to cures
Sea urchins are small and spiny, they have no eyes and they eat kelp and algae. Still, the sea creature's genome is remarkably similar to humans' and may hold the key to preventing and curing several human diseases, according to a University of Central Florida researcher and several colleagues. view more (2006-12-08)
The genes involved in rheumatoid arthritis identified
The human genome has now been thoroughly screened in the hunt for the genetic causes of rheumatoid arthritis. The results, which both confirms previous hypotheses and turn the spotlight on entirely new genes, are presented in two articles in the prestigious New England Journal of Medicine. view more (2007-09-07)
Botulism bug has few genome wrinkles
The genome of the organism that produces the world's most lethal toxin is revealed today. This toxin is the one real weapon in the genome of Clostridium botulinum and less than 2 kg - the weight of two bags of sugar - is enough to kill every person on the planet. view more (2007-05-24)
Study finds value in 'junk' DNA
For about 15 years, scientists have known that certain "junk" DNA -- repetitive DNA segments previously thought to have no function -- could evolve into exons, which are the building blocks for protein-coding genes in higher organisms like animals and plants. view more (2008-10-17)
