Scientists harvest answers from genome of grain fungus
Evil forces thrive in an unstable environment. At least, that's the picture being painted in the first waves of data being reaped from the genome sequence of the fungal plant pathogen, Fusarium graminearum. view more (2007-09-07)
Toward a faster prenatal test for Down syndrome
Scientists in California are reporting an advance toward rapid testing for pre-natal detection of Down syndrome and other birth defects that involve an abnormal number of chromosomes. view more (2007-09-19)
Enhanced skin cancer risk linked to defects in cellular aging controls
Cell lifespan is limited by telomeres, DNA sequences that cap chromosomes and control the number of times a cell may be copied. A new study reported in Disease Models & Mechanisms (DMM), dmm.biologists.org, describes how telomere dysfunction in skin cells can lead to increased skin cancer risk and pigmentation. view more (2009-02-23)
Study links dietary folate intake to genetic abnormalities in sperm
Healthy men who report lower levels of the nutrient folate in their diets have higher rates of chromosomal abnormalities in their sperm, according to a new study by researchers at the University of California, Berkeley, and the Lawrence Berkeley National Laboratory. view more (2008-03-20)
Female human embryos adjust the balance of X chromosomes before implantation
Dutch researchers have found the first evidence that a process of inactivating the X chromosome during embryo development and implantation, which was known to occur in mice but unknown in humans, does, in fact, take place in human female embryos prior to implantation in the womb. view more (2009-06-30)
Researchers use chemical from medicinal plants to fight HIV
Like other kinds of cells, immune cells lose the ability to divide as they age because a part of their chromosomes known as a telomere becomes progressively shorter with cell division. As a result, the cell changes in many ways, and its disease fighting ability is compromised. view more (2008-11-10)

A statistical approach to studying genetic variation promises to shed new light on the history of human migration. view more (2008-05-23)
Effectiveness of mouse breeds that mimic Alzheimer's disease symptoms questioned
Scientists have shown that recently developed mouse breeds that mimic the symptoms of Alzheimer's disease (AD) may not be as effective as previously assumed. view more (2007-08-17)
Gene's discovery could help prevent a leading cause of blindness in the elderly
University of Pittsburgh researchers have discovered a gene linked to age-related maculopathy (ARM), the leading cause of untreatable blindness in the elderly. view more (2005-08-17)
A youthful boost for Austrian plant research - New career opportunities at the Gregor Mendel Institute, Vienna
GMI Young Investigator is a new career level at the Campus Vienna Biocenter. The introduction of this position by the Gregor Mendel Institute of Molecular Plant Biology of the Austrian Academy of Sciences will enable young, brilliant plant biologists both from Austria and abroad to lead independent study groups. The 32-year old Dr. Karel Riha has... view more... (2005-03-16)
Genetic cause of speech defect discovered
Researchers at the University of Toronto (U of T), Capital Health's Stollery Children's Hospital in Edmonton, Toronto's Hospital for Sick Children and their international collaborators have discovered a genetic abnormality that causes a type of language impairment in children. view more (2005-10-20)
New tumor markers determine therapy intensity
Characteristic changes in the DNA of medulloblastoma, the most frequent malignant brain tumor in childhood, indicate precisely how aggressively the tumor will continue to spread and what the chances of disease relapse are. view more (2009-03-18)
Geneticists aim to develop test to identify learning disability
Clinical geneticist and principal investigator Dr David FitzPatrick explains: "In approximately 10% of CGMH cases, the condition will be caused by a chromosomal abnormality such as a chromosome 21 problem as in Down's Syndrome. Recent studies have suggested that a further 6% of cases may be caused by tiny sub-microscopic abnormalities at the ends... view more... (2000-01-20)
Researchers Identify Specific Lung Cancer Susceptibility Gene
University of Cincinnati (UC) cancer cell biologists have identified a distinct gene linked to increased lung cancer susceptibility and development. view more (2009-04-16)
Bovine genome provides clues to possible new developments
Scientists from Texas AgriLife Research and the Texas A&M University College of Veterinary Medicine & Biomedical Sciences (CVM) are part of a consortium of researchers who have developed an annotated sequence of the cattle genome which could lead to better disease resistance and higher quality meat for consumers, the researchers say. view more (2009-04-24)
Y chromosome study sheds light on Athapaskan migration to southwest US
A large-scale genetic study of native North Americans offers new insights into the migration of a small group of Athapaskan natives from their subarctic home in northwest North America to the southwestern United States. The migration, which left no known archaeological trace, is believed to have occurred about 500 years ago. view more (2008-07-16)
Chromosomal problems affect nearly all human embryos
For the first time, scientists have shown that chromosomal abnormalities are present in more than 90% of IVF embryos, even those produced by young, fertile couples. view more (2009-07-01)
University of Sheffield plays crucial role in sequencing chicken genome
Scientists at the University of Sheffield have played a major role in sequencing the chicken genome, published in Nature and Genome Research on Thursday 9 December. The chicken is the first farm animal to be successfully sequenced, as well as being the first bird. view more (2004-12-07)
Simple reason helps males evolve more quickly
he observation that males evolve more quickly than females has been around since 19th century biologist Charles Darwin noted the majesty of a peacock's tail feather in comparison with the plainness of the peahen's. view more (2007-11-15)
