Nobody Is Perfect: Study Shows People Have 400 Genetic Flaws In DNA
2012-12-07 12:45:35

Lawrence LeBlond for redOrbit.com - Your Universe Online Perfection is something that all humans strive for at one time or another, be it scoring a perfect 100 on a test, making the perfect soufflé, having the perfect play in basketball, or even landing the perfect job. For others, perfection is a state of well-being–as in being perfectly healthy. While achieving perfect health may be plausible in sense of how one feels, new research shows that, at the genetic level,...

Biologists at Mainz University achieve repair and read-through of stop mutations responsible for the disease After years of basic research, scientists at Johannes Gutenberg University Mainz (JGU) are increasingly able to understand the mechanisms underlying the human Usher syndrome and are coming ever closer to finding a successful treatment approach. The scientists in the Usher research group of Professor Dr. Uwe Wolfrum are evaluating two different strategies. These involve either the...

Researchers from the University of Geneva demonstrate that, in this type of lesion, the rate of progression from a precancerous state to the tumor stage accelerates over time The causes underlying the development of certain types of common cancers have not yet been elucidated. In order to better determine the origin and the sequence of events responsible for the onset of colon cancer, the teams led by Thanos Halazonetis and Stylianos Antonarakis, professors at the University of Geneva...

Gene Mutations Begin Showing Up In Last 5,000 Years Of Human Evolution
2012-11-29 10:51:10

Lawrence LeBlond for redOrbit.com - Your Universe Online In a world that´s more than 4 billion years old, humans have only existed for a fraction of that–roughly 200,000 years. In those 200,000 years of existence, not a lot is known about genetic mutation until we close in on the last 5 to 10 thousand years. It is within that time that researchers believe nearly 75 percent of gene mutations have occurred, making our DNA distinctly different now than it was way back when. This...

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...

Researchers find that gene related to germ cell formation is far older than first thought Harvard scientists have solved the long-standing mystery of how some insects form the germ cells — the cellular precursors to the eggs and sperm necessary for sexual reproduction — and the answer is shedding new light on the evolutionary origins of a gene that had long been thought to be critical to the process. As described in a November 1 paper published in Current Biology, a team of...

Genetic Analysis Shows Reasons Behind Selkirk Rex Curly Hair
2012-10-31 04:52:21

April Flowers for redOrbit.com - Your Universe Online Appearance plays a large part in choosing a mate, whether that is your human spouse or your animal pet. Many human societies place a high value on curly hair for appearance — as generations of perm-offering hair dressers can attest. It should be no surprise that pet owners and breeders are attracted to curly haired animals more frequently. Three curly-haired varieties have been recognized and developed into competitive breeds...

Evolution Follows A Predictable Genetic Pattern Researchers Find
2012-10-26 10:20:03

Evolution, often perceived as a series of random changes, might in fact be driven by a simple and repeated genetic solution to an environmental pressure that a broad range of species happen to share, according to new research. Princeton University research published in the journal Science suggests that knowledge of a species' genes – and how certain external conditions affect the proteins encoded by those genes – could be used to determine a predictable evolutionary pattern...

Like job-seekers searching for a new position, living things sometimes have to pick up a new skill if they are going to succeed. Researchers from the University of California, Davis, and Uppsala University, Sweden, have shown for the first time how living organisms do this. The observation, published Oct. 19 in the journal Science, closes an important gap in the theory of natural selection. Scientists have long wondered how living things evolve new functions from a limited set of genes....


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
