Researchers identify key proteins that help establish cell function Researchers at the University of California, San Diego School of Medicine have developed a new way to parse and understand how special proteins called "master regulators" read the genome, and consequently turn genes on and off. Writing in the October 13, 2013 Advance Online Publication of Nature, the scientists say their approach could make it quicker and easier to identify specific gene mutations associated with...

Sometimes, when the DNA in a cell is copied during cell division, there is a mistake. A large portion of the genetic material could be duplicated or deleted. In each instance, there is often a greatly enhanced potential for serious genetic disease. Such changes are known as copy number variation (CNV) referring to the numbers of copies of a gene. Instead of ‘letters of the DNA alphabet’ being changed or missing, whole sentences, entire paragraphs or even pages/volumes of the encyclopedia...

Concealed within the vastness of the human genome, (comprised of some 3 billion base pairs), mutations are commonplace. While the majority of these appear to have neutral effect on human health, many others are associated with diseases and disease susceptibility. Reed Cartwright, a researcher at Arizona State University's Biodesign Institute, along with colleagues at ASU, Washington University and the Wellcome Trust Sanger Institute, Cambridge, UK, report on a new software tool known as...

Genetic Hitchhikers Picked Up By Evolution
2013-07-23 11:01:42

Princeton University In a twist on "survival of the fittest," researchers have discovered that evolution is driven not by a single beneficial mutation but rather by a group of mutations, including ones called "genetic hitchhikers" that are simply along for the ride. These hitchhikers are mutations that do not appear to have a role in contributing to an organism's fitness and therefore its evolution, yet may play an important role down the road. Researchers from Princeton University...

Certain mutated cells keep trying to replicate their DNA – with disastrous results – even after medications rob them of the raw materials to do so, according to new research from USC. New imaging techniques allowed scientists to see for the first time that while chemotherapy drugs shut down the DNA replication process of most cancer cells, so-called "checkpoint mutants" just keep chugging along, unwinding the DNA and creating damaged DNA strands that can result in the kind of...


Word of the Day
caparison
  • A cloth or covering, more or less ornamented, laid over the saddle or furniture of a horse, especially of a sumpter-horse or horse of state.
  • Clothing, especially sumptuous clothing; equipment; outfit.
  • To cover with a caparison, as a horse.
  • To dress sumptuously; adorn with rich dress.
This word ultimately comes from the Medieval Latin 'cappa,' cloak.
