First whole-genome scan for links to OCD reveals evidence for genetic susceptibility
A federally funded team of researchers including several from Johns Hopkins have identified six regions of the human genome that might play a role in susceptibility to obsessive compulsive disorder, or OCD. view more (2006-06-08)
Human and chimp genomes reveal new twist on origin of species
The evolutionary split between human and chimpanzee is much more recent - and more complicated - than previously thought. view more (2006-05-18)
Human ageing gene found in flies
Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have found a fast and effective way to investigate important aspects of human ageing. view more (2008-05-12)
New research finds possible genetic link to cause of pregnancy loss and disorders
Scientists at the University of Tennessee, Knoxville, and Lawrence Berkeley National Laboratory (LBNL) have published new findings about a cause of a condition at the root of genetic disorders such as Down Syndrome, pregnancy loss and infertility. view more (2009-07-22)
Scientists discover role for dueling RNAs
Researchers have found that a class of RNA molecules, previously thought to have no function, may in fact protect sex cells from self-destructing. view more (2006-11-17)
DNA could reveal your surname
Scientists at the world-leading Department of Genetics at the University of Leicester - where the revolutionary technique of genetic fingerprinting was invented by Professor Sir Alec Jeffreys- are developing techniques which may one day allow police to work out someone's surname from the DNA alone. view more (2008-10-08)
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)
Protein complex key in avoiding DNA repair mistakes, cancer
As the body creates antibodies to fight invaders, a three-protein DNA repair complex called MRN is crucial for a normal gene-shuffling process to proceed properly, University of Michigan research shows. view more (2009-08-05)
Draft potato genome based on unique potato variety
The Potato Genome Sequencing Consortium (PGSC), an international team of scientists from industry and academia in 14 countries, has released a draft sequence of the potato genome with the help of a Virginia Tech researcher. view more (2009-09-28)
Handle with care: Telomeres resemble DNA fragile sites
Telomeres, the repetitive sequences of DNA at the ends of linear chromosomes, have an important function: They protect vulnerable chromosome ends from molecular attack. view more (2009-07-10)
Bioclocks work by controlling chromosome coiling
In recent years, scientists have discovered that biological clocks help organize a dizzying array of biochemical processes in the body. Despite a number of hypotheses, exactly how the microscopic pacemakers in every cell in the body exert such a widespread influence has remained a mystery. view more (2007-11-26)
A solution to Darwin's 'mystery of the mysteries' emerges from the dark matter of the genome
Biological species are often defined on the basis of reproductive isolation. Ever since Darwin pointed out his difficulty in explaining why crosses between two species often yield sterile or inviable progeny (for instance, mules emerging from a cross between a horse and a donkey), biologists have struggled with this question. view more (2009-10-27)
Mutating the entire genome
Genes account for only 2.5 percent of DNA in the human genetic blueprint, yet diseases can result not only from mutant genes, but from mutations of other DNA that controls genes. view more (2007-06-18)
Received Truth Turned On End In Cancer Research
It has long been the accepted view of cancer researchers that there is a difference between the mechanism behind the development of leukemias, on the one hand, and solid tumors like breast cancer, prostate cancer, gastrointestinal cancer, etc, on the other. A research team at the Section for Clinical Genetics at Lund University in Sweden is now... view more... (2004-04-06)
Stanford study uses genetic evidence to trace ancient African migration
Stanford University researchers peering at history's footprints on human DNA have found new evidence for how prehistoric people shared knowledge that advanced civilization. view more (2008-08-05)
Common weed could provide clues on aging and cancer
A common weed and human cancer cells could provide some very uncommon details about DNA structure and its relationship with telomeres and how they affect cellular aging and cancer, according to a team led by scientists from Texas A&M University and the University of Cincinnati (UC). view more (2009-10-27)
A little telomerase isn't enough
Chromosome ends, or telomeres, are repetitive stretches of DNA that protect chromosomes in much the same way as plastic tips on shoelaces prevent the fabric from fraying. view more (2005-12-23)
Mice regain ability to extend telomeres suggesting potential for dyskeratosis congenita therapy
The human genetic disease dyskeratosis congenita (DKC) is an autosomal dominant disease that leads to abnormalities in tissues with a rapid cell turnover - the skin, nails, bone marrow, lungs and gut. view more (2009-10-19)
Recent advances at Institute of Food Research
The latest issue of Institute of Food Research (IFR) News (Issue 2.00) describes some of our most recent publications. Understanding Evolution: Ian Roberts and Steve James, with colleagues from the Universities of Manchester and Oxford, are trying to understand how chromosomes evolve. Their research, published in Nature, has shown that... view more... (2000-07-12)
DNA repair in mammal embryos is a matter of timing
Investigators at St. Jude Children's Research Hospital have discovered that the cells of the developing nervous system of the mammalian embryo have an exquisite sense of timing when it comes to fixing broken chromosomes: the cells use one type of repair mechanism during the first half of development and another during the second half. view more (2006-06-20)
