Research led by a scientist at the University of York has thrown new light on the way breakdowns in the DNA copying process inside cells can contribute to cancer and other diseases. Peter McGlynn, an Anniversary Professor in the University's Department of Biology, led a team of researchers who have discovered that the protein machines that copy DNA in a model organism pause frequently during this copying process, creating the potential for dangerous mutations to develop. The research,...

St. Jude Children's Research Hospital ties mutations in 2 genes to the death of motor neurons associated with ALS, or Lou Gehrig's disease, and other devastating neurodegenerative problems A study led by St. Jude Children's Research Hospital has discovered mutations in two genes that lead to the death of nerve cells in amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, and related degenerative diseases. The same mutation occurred in both genes and led to the...

Mutant Champions Save Vulnerable Species From Almost-certain Extinction
2013-02-20 12:52:16

University of Washington Species facing widespread and rapid environmental changes can sometimes evolve quickly enough to dodge the extinction bullet. Populations of disease-causing bacteria evolve, for example, as doctors flood their “environment,” the human body, with antibiotics. Insects, animals and plants can make evolutionary adaptations in response to pesticides, heavy metals and overfishing. Previous studies have shown that the more gradual the change, the better the...

A genetically mosaic Eucalyptus tree is able to control which leaves are saved from predation because of alterations in its genes, finds an study published in BioMed Central's open access journal BMC Plant Biology. Between two leaves of the same tree there can be many genetic differences — this study found ten SNP, including ones in genes that regulate terpene production, which influence whether or not a leaf is edible. Organisms collect somatic genetic mutations throughout their...

Imagine two steel springs identical in look and composition but that perform differently because each was tempered at a different rate. A team of researchers including a Texas A&M University molecular biologist has shown that concept – that the speed of creation affects performance – applies to how a protein they studied impacts an organism's circadian clock function. This discovery provides new insights into the significance of the genetic code for controlling the rates at...

Scientist Recommends Research Method Change For Evolutionary Biology
2013-02-16 08:11:00

April Flowers for redOrbit.com — Your Universe Online Shozo Yokoyama, a biologist at Emory University, says evolutionary biologists need to shift their focus from present-day molecules to synthesized, ancestral ones to truly understand the mechanisms of natural selection. Yokoyama presented evidence to support his claim at the American Academy of Arts and Sciences (AAAS) meeting in Boston this week. "This is not just an evolutionary biology problem, it's a science problem,"...

Genetic Variation Helped Humans Evolve, Adapt To Climate Changes

[Watch Video: 2 Studies Reveal Genetic Variation That Drives Human Evolution] April Flowers for redOrbit.com - Your Universe Online New light has been shed on a genetic variation that may have played a key role in human evolution by two studies published by an international group of researchers this week in the journal Cell. To understand a gene variant that might have helped humans adapt to humid climates, the research team used an animal model, along with whole-genome sequencing...

Information prompts individuals to consult physician, inform relatives A 23andMe study of consumers' reactions to genetic testing found that even when the tests revealed high-risk mutations in individuals, those individuals had few negative reactions to the news. Instead of inducing serious anxiety, the test results prompted people to take positive steps, including follow-up visits with a doctor and discussions with family members who could also be at risk. The study, titled "Dealing...
