Midwestern growers don't worry much about soybean rust, but the fungal disease has been popping up at the end of the growing season nearly every year since 2006. But because the fungus can't survive winter without a host plant, it's not much of a threat to Midwest crops under current conditions. But it's a major problem for soybean growers in Africa and South America. University of Illinois researchers have evaluated which strains are most virulent.
EPFL scientists have discovered an important gene whose loss lies behind follicular lymphoma, an incurable cancer.
By comparing variations in protein expression in tumor samples from a single melanoma patient, researchers from the Johns Hopkins Bloomberg~Kimmel Institute and the Memorial Sloan-Kettering Cancer Center say their findings have the potential to reveal some of the mechanisms underlying response or resistance to immunotherapy drugs.
Scientists have closed in on specific genes responsible for Inflammatory Bowel Disease (IBD) from a list of over 600 genes that were suspects for the disease. The team from the Wellcome Trust Sanger Institute and their collaborators at the Broad Institute of MIT and Harvard and the GIGA Institute of the University of Liège combined efforts to produce a high resolution map to investigate which genetic variants have a causal role in the disease.
Examining human remains and other archaeological evidence from a site at nearly 12,500 feet above sea level in Peru, the scientists show that intrepid hunter-gatherers -- men, women and children -- managed to survive at high elevation before the advent of agriculture, in spite of lack of oxygen, frigid temperatures and exposure to elements.
The CHD8 gene is associated with some cases of human autism. A new study shows that mice with mutated CHD8 show defects in brain development and behavioral changes, and may give insight into genetic causes of autism spectrum disorders.
But the woodrats' unique adaptation that allows them to break down creosote toxins may be in jeopardy if temperatures continue to rise, according to University of Utah researchers. Their new study in Molecular Ecology explains why: Livers of mammals (including us) may be less efficient at breaking down toxins at higher temperatures.
The airborne dust carried in sand storms affects the health of people and ecosystems alike. New research at the Weizmann Institute of Science suggests that part of the effect might not be in the particles of dust but rather in bacteria that cling to them, traveling many kilometers in the air with the storms.
A new approach to finding Alzheimer's disease (AD) causative genes was estimated by paying attention to special duplicated genes called 'ohnologs' included in the genomic region specific to AD patients.Human ohnologs, which are vulnerable to change in number, were generated by whole genome duplications 500 million years ago.
A study of yeast reveals new mechanism that allows cells to adapt to environmental changes more rapidly by accelerating genetic changes around genes that boost fitness, publishing June 27 in the open access journal PLOS Biology, by Dr. Jon Houseley and colleagues at the Babraham Institute in Cambridge, UK.
