Protecting the genome from transposon activation
Transposons are foreign DNA elements capable of random insertion into the genome, an event that can be very dangerous for a cell. Their activity must be silenced to maintain genomic integrity, which is primarily achieved by H3K9me3-mediated repressio.....»»
Prevalence of transposable elements may provide clues to worldwide mammal biodiversity
An international scientific project that compares the genomes of 240 living species of mammals has identified transposable elements (TEs)—genes that can change their position within a genome, creating or reversing mutations and thus altering a cell.....»»
Artificial photosynthesis for environmentally friendly food production
Ensuring the supply of food to the constantly growing world population and protecting the environment at the same time are often conflicting objectives. Now researchers at the Technical University of Munich (TUM) have successfully developed a method.....»»

Genome of famed sled dog Balto reveals genetic adaptations of working dogs
The sled dog Balto has been celebrated in books and movies for his role in delivering desperately needed diphtheria antitoxin to Nome, Alaska, in 1925. Now, his DNA has enabled scientists to explore the genetics of 1920s sled dogs in Alaska and under.....»»
Study suggests catalyst for human brain evolution
More than a million years ago, large chunks of the human genome were rearranged—a chance event during egg or sperm formation that led to the deletion, duplication, or reversal of sections of DNA. Those structural variants, researchers have now disc.....»»
Genomes from 240 mammalian species reveal what makes the human genome unique
Over the past 100 million years, mammals have adapted to nearly every environment on Earth. Scientists with the Zoonomia Project have been cataloging the diversity in mammalian genomes by comparing DNA sequences from 240 species that exist today, fro.....»»
Information "deleted" from the human genome may be what made us human
What the human genome is lacking compared with the genomes of other primates might have been as crucial to the development of humankind as what has been added during our evolutionary history, according to a new study led by researchers at Yale and th.....»»
Scientists sequenced the genome of Balto, famous sled dog of 1925 “Serum Run”
Balto was just part Siberian husky and, contrary to popular legend, not part wolf. Enlarge / After Balto died in 1933, his taxidermy mount was put on display at the Cleveland Museum of Natural History. (credit: Cleveland Museum o.....»»
New insights into the evolutionary phylogeny of the ciliate order Sessilida
Ciliated protists represent one of the most primitive lineages of eukaryotes, with nuclear dimorphism, a distinctive sexual process (conjugation), and extensive genome rearrangements. Sessilida, among diverse ciliate lineages, is the only group conta.....»»
In protecting land for wildlife, size matters—here"s what it takes to conserve very large areas
Driving north on state Highway 66 through the Fort Belknap Indian Reservation in central Montana, it's easy to miss a small herd of bison lounging just off the road behind an 8-foot fence. Each winter, heavy snows drive bison out of Wyoming's Yellows.....»»
