"Silent" mutations found to have repercussions beyond their own gene
Genetic disorders—like cystic fibrosis and Huntington's disease—are considered incurable, with gene mutations occurring in essentially every cell of the body. Gene mutations occur when one nucleotide in a codon is switched. In non-synonymous muta.....»»
Study reveals isolation, endogamy and pathogens in early medieval Spanish community
An archaeogenetic study sheds new light on the isolated medieval community Las Gobas in northern Spain. Besides isolation and endogamy, researchers have also identified the variola virus, which can offer a new explanation of how smallpox entered Iber.....»»
Light microscopy study reveals molecular density changes during mitotic chromosome condensation
A team of scientists studying cell division developed a special light microscopy system and used it to analyze the molecular density of cellular environments. Their results provide a novel insight into mitotic chromosome condensation in living human.....»»
