Nanobacteria in clouds could spread disease, scientists claim

...ndensation nuclei, with a tendency to aggregate to clusters upon contact." Their work corroborates the findings of Ruprecht Jaenicke, of the Institute for Atmospheric Physics at Mainz University, Germany, on bioaerosols (airborne contaminants) and proteins in the atmosphere reported in New Scientist (31 Marc...

Precise Timing Enabled Pig-to-rat Transplants To Cure Diabetes

...ng organs from stem cells and other embryonic cell clusters known as organ primordia. Unlike embryonic stem cells, which can become virtually any cell type, primordia are locked into becoming a particular cell type or one of a particular set of cell types that make up an organ. In their earlier studies, Hamm...

Genpathway and Baylor College of Medicine Identify New Genes in Breast Cancer

... of odorant receptor are targeted to several loose clusters of neurons at specific locations in the cortex, " said Buck. In sharp contrast to the olfactory bulb, where signals from different receptors are segregated, inputs from different odorant receptors overlap extensively in the cortex. Moreover, individu...

In sharp contrast to the olfactory bulb, where signals from different receptors are segregated, inputs from different odorant receptors overlap extensively in the cortex. Moreover, individu...

CoPub Mapper: mining MEDLINE based on search term co-publication

...h CoPub Mapper, which resulted in several relevant clusters of genes with biological process and disease keywords. In addition, all genes versus keywords were hierarchical clustered to reveal a complete grouping of published genes based on co-occurrence. The CoPub Mapper program allows for quick and versatil...

Researchers uncover sequence of major rice pathogen

... Dean says, so one focus will be to take apart the clusters and learn more about toxins and their production. "The primary mission is to uncover the organism's weaknesses. You do that by building up an arsenal of information of what genes are involved in plant-pathogen interactions," Dean says. In July 2002...

Asthma gene clusters identified

...nvolved in asthma, but this is the first time that clusters of known genes have been identified as being activ... examined 54,675 genes. They discovered eight gene clusters in all, consisting of 161 genes. At least one cluster was identified that was comprised of genes act...

Unexpressed But Indispensable -- The DNA Sequences That Control Development

...ntrolling access to their associated gene. Several clusters also appear in regions without any known genes—the identification of these clusters might lead to the discovery of new developmentally significant genes. While “in silico?discoveries ...

Examination of internal 'wiring' of yeast, worm, and fly reveals conserved circuits
