Bat DNA Analysis Provides Key Evolutionary Insights
2012-12-21 14:56:48

Brett Smith for redOrbit.com - Your Universe Online A comparative genetic analysis of two distantly related bat species has revealed new insights into the evolutionary development of flight and disease resistance, according to a new report in the latest edition of the journal Science. As the only mammals capable of sustained flight, bats are an anomaly in the animal world. They also have a predilection for transmitting diseases that do not appear to affect the animals themselves....

Autism And Other Disorders May Be Caused By Genetic Hotspot Mutations
2012-12-21 06:47:01

[ Watch the Video: Mutation Hotspots in Autism Genes ] Connie K. Ho for redOrbit.com — Your Universe Online A group of international researchers led by a team of investigators from the School of Medicine at the University of California, San Diego (UCSD), recently revealed a new study that provides signals as to the causes of autism and other related disorders. With the findings, it is possible that there are elevated mutation rates in specific parts of the genome that adds to...

How does evolution innovate? We exist because our ancestors have had the ability to adapt successfully to changes in their environment; however, merely examining present-day organisms can limit our understanding of the actual evolutionary processes because the crucial events have been masked by the passage of aeons — what we need is a time machine. Scientists from VIB, KU Leuven, University of Ghent and Harvard have done the next-best thing; by reconstructing DNA and proteins from...

Daily Liver Cycles Controlled By More Than 3,000 Epigenetic Switches

Salk Institute Salk findings may help explain connections between dietary schedules and chronic disease When it's dark, and we start to fall asleep, most of us think we're tired because our bodies need rest. Yet circadian rhythms affect our bodies not just on a global scale, but at the level of individual organs, and even genes. Now, scientists at the Salk Institute have determined the specific genetic switches that sync liver activity to the circadian cycle. Their finding gives...

Physicists and biologists apply Big Data statistical tools to study marine plant evolution A new method that could give a deeper insight into evolutional biology by tracing directionality in gene migration has just appeared in EPJ Data Science. Paolo Masucci from the Centre for Advanced Spatial Analysis, at University College of London, UK, and colleagues identified the segregation of genes that a marine plant underwent during its evolution. They found that the exchange of genes, or gene...

Cell Press Vertebrates' transition to living on land, instead of only in water, represented a major event in the history of life. Now, researchers reporting in the December issue of the Cell Press journal Developmental Cell provide new evidence that the development of hands and feet occurred through the gain of new DNA elements that activate particular genes. "First, and foremost, this finding helps us to understand the power that the modification of gene expression has on shaping our...

A 'network map' of genes involved in pain perception Scientists in Australia and Austria have described a "network map" of genes involved in pain perception. The work, published in the journal PLOS Genetics should help identify new analgesic drugs. Dr Greg Neely from the Garvan institute of Medical Research in Sydney and Professor Josef Penninger from the Austrian Academy of Sciences in Vienna had previously screened the 14,000 genes in the fruit fly genome and identified 580 genes...

Knockout Mouse
2013-10-02 11:52:01

A Knockout Mouse is a genetically engineered mouse in which researchers have inactivated, or “knocked out,” an existing gene by replacing it or disrupting it with an artificial piece of DNA. The loss of gene activity frequently causes changes in a mouse’s phenotype, which includes appearance, behavior, or other apparent and biochemical characteristics. Knockout mice are significant animal models for studying the role of genes which have been sequenced but whose functions haven’t...
