Exon-skipping drug prevents muscle wasting, maintains muscle function in dystrophin deficient mice

Oxford, United Kingdom & Bothell, WA, USA -- October 20, 2009 -- An exon skipping PPMO has demonstrated dramatic effects in the prevention and treatment of severely affected, dystrophin and utrophin-deficient mice, preventing severe deterioration of the treated animals and extending their lifespan.

Could antioxidants make us more, not less, prone to diabetes? Study says yes

We've all heard about the damage that reactive oxygen species (ROS) -- aka free radicals -- can do to our bodies and the sales pitches for antioxidant vitamins, skin creams or "superfoods" that can stop them. In fact, there is considerable scientific evidence that chronic ROS production within cells can contribute to human diseases, including insulin resistance and type 2 diabetes.

East African cichlid fish offer new understanding of genetic basis of sex determination

Biologists have genetically mapped the sex chromosomes of several species of cichlid fish from Lake Malawi, East Africa, and identified a mechanism by which new sex chromosomes may evolve.

Genetic conflict in fish led to evolution of new sex chromosomes

University of Maryland biologists have genetically mapped the sex chromosomes of several species of cichlid (pronounced "sick-lid") fish from Lake Malawi, East Africa, and identified a mechanism by which new sex chromosomes may evolve. In research published in the journal Science (October 1, 2009), Professor Thomas D.

Finding the ZIP-code for gene therapy: Scientists imitate viruses to deliver therapeutic genes

A research report featured on the cover of the September 2009 print issue of The FASEB Journal (http://www.fasebj.org) describes how Australian scientists developed a new gene therapy vector that uses the same machinery that viruses use to transport their cargo into our cells.

Possible dinosaur burrows clues to survival strategies

Internationally renowned palaeontologist and Monash University Honorary Research Associate, Dr Anthony Martin has found evidence of a dinosaur burrow along the coast of Victoria, which helps to explain how dinosaurs protected themselves from climate extremes during the Cretaceous period -- the final era for dinosaurs before their extinction.

Researchers achieve major breakthrough with water desalination system

Concern over access to clean water is no longer just an issue for the developing world, as California faces its worst drought in recorded history. According to state's Department of Water Resources, supplies in major reservoirs and many groundwater basins are well below average.

Down Under dinosaur burrow discovery provides climate change clues

On the heels of his discovery in Montana of the first trace fossil of a dinosaur burrow, Emory University paleontologist Anthony Martin has found evidence of more dinosaur burrows -- this time on the other side of the world, in Victoria, Australia.

A new measure of global warming from carbon emissions

Damon Matthews, a professor in Concordia University's Department of Geography, Planning and the Environment has found a direct relationship between carbon dioxide emissions and global warming.

Archeological evidence of human activity found beneath Lake Huron

ANN ARBOR, Mich.---More than 100 feet deep in Lake Huron, on a wide stoney ridge that 9,000 years ago was a land bridge, University of Michigan researchers have found the first archeological evidence of human activity preserved beneath the Great Lakes.

The researchers located what they believe to be caribou-hunting structures and camps used by the early hunters of the period.

Sharing surgical lessons from the Canadian field hospital in Afghanistan

Lessons learned at the Canadian-run military hospital in Kandahar, Afghanistan could help surgeons prepare for civilian disasters, according to a London, Ontario physician who has served two tours at the hospital. Dr.

Windy, wet and wild: Victoria Crater unveils more of Mars' geologic past

ITHACA, N.Y. -- After thoroughly investigating Victoria Crater on Mars for two years, the instruments aboard the Rover Opportunity reveal more evidence of our neighboring red planet's windy, wet and wild past. The overview of the findings ? compiled in one source ? is published in the latest issue of the journal Science (May 22, 2009).

Fire is an important and under-appreciated part of global climate change

Fire must be accounted for as an integral part of climate change, according to 22 authors of an article published in the April 24 issue of the journal Science. The authors determined that intentional deforestation fires alone contribute up to one-fifth of the human-caused increase in emissions of carbon dioxide, a heat-trapping gas that increases global temperature.

Minimizing the spread of deadly Hendra virus

Groundbreaking CSIRO research into how the deadly Hendra virus spreads promises to save the lives of both horses and humans in the future.

CSIRO Livestock Industries' scientists working at the Australian Animal Health Laboratory (AAHL), in Geelong Victoria, have made a major breakthrough in better understanding how Hendra spreads from infected horses to other horses and humans.
