Preclinical studies show that gene therapy can improve muscle strength in small- and large-animal models of a fatal congenital childhood disease know as X-linked myotubular myopathy.
The findings, appearing as the cover story in the January 22, 2014 issue of Science Translational Medicine, also demonstrate the feasibility of future clinical trials of gene therapy for this devastating disease. (more…)
Geologic time is shorthand for slow-paced. But new measurements from steep mountaintops in New Zealand shows that rock can transform into soil more than twice as fast as previously believed possible.
The findings were published Jan. 16 in the early online edition of Science. (more…)
Almost one in 10 people will someday experience a kidney stone, which creates what is described as the most intense pain imaginable. This increasingly common condition leads to hundreds of thousands of surgeries in the United States each year.
A new device developed at the University of Washington would let doctors use ultrasound to move kidney stones inside the body and help them pass by natural means. (more…)
Pine Island Glacier is one of the biggest routes for ice to flow from Antarctica into the sea. The floating ice shelf at the glacier’s tip has been melting and thinning for the past four decades, causing the glacier to speed up and discharge more ice.
Understanding this ice shelf is a key for predicting sea-level rise in a warming world. A paper published Jan. 2 in the advance online version of the journal Science shows that the ice shelf melting depends on the local wind direction, which is tied to tropical changes associated with El Niño.

A scalyhead sculpin is a small, rather drab, nondescript fish.
But “stripped” to its skeleton and stained, it suddenly becomes a striking specimen in vivid blues and crimson.
Striking enough to be among the 14 photos by Adam Summers, University of Washington professor of biology, in his “Cleared: The Art of Science” on display now through spring 2014 at the Seattle Aquarium. (more…)
Like humans, some song sparrows are more effusive than others, at least when it comes to defending their territories. New findings from the University of Washington show that consistent individual differences exist not only for how aggressive individual song sparrows are but also for how much they use their signals to communicate their aggressive intentions.
The findings, published online Dec. 4 in Proceedings of the Royal Society B, show that while many birds signal their intentions clearly, other “strong silent types” go immediately to aggressive behavior and ultimately attack without first signaling their intentions. (more…)
Quantum entanglement, a perplexing phenomenon of quantum mechanics that Albert Einstein once referred to as “spooky action at a distance,” could be even spookier than Einstein perceived.
Physicists at the University of Washington and Stony Brook University in New York believe the phenomenon might be intrinsically linked with wormholes, hypothetical features of space-time that in popular science fiction can provide a much-faster-than-light shortcut from one part of the universe to another.

The mystery of how the surface of Mars, long dead and dry, could have flowed with water billions of years ago may have been solved by research that included a University of Washington astronomer.
There is evidence that Mars had water at its surface 3.8 billion years ago or before, but scientists are divided on how that might have happened, especially since the sun was about 30 percent fainter back then, thus less able to melt water ice on Mars. (more…)
