Recent Antarctic climate, glacier changes at the ‘upper bound’ of normal

In the last few decades, glaciers at the edge of the icy continent of Antarctica have been thinning, and research has shown the rate of thinning has accelerated and contributed significantly to sea level rise.

New ice core research suggests that, while the changes are dramatic, they cannot be attributed with confidence to human-caused global warming, said Eric Steig, a University of Washington professor of Earth and space sciences. (more…)

New device could cut costs on household products, pharmaceuticals

Sometimes cost saving comes in nanoscale packages.

A new procedure that thickens and thins fluid at the micron level could save consumers and manufacturers money, particularly for soap products that depend on certain molecules to effectively deal with grease and dirt. Researchers at the University of Washington published their findings online April 9 in the Proceedings of the National Academy of Sciences.

Read the back of most shampoos and dishwashing detergents and you’ll find the word “surfactant” in the list of active ingredients. Surfactant molecules are tiny, yet they are the reason dish soap can attack an oily spot and shampoo can rid the scalp of grease. (more…)

New book explores Harry Truman’s record on civil liberties

Richard Kirkendall is a University of Washington professor emeritus of history and editor of the new book “Civil Liberties and the Legacy of Harry S. Truman.” He answered a few questions about the book for UW Today.

Q: What’s the scope of the book?

A: The book surveys the civil liberties issue during the Truman presidency of 1945-1953, an especially important time in the history of this essential feature of the American political system.

The book begins with two chapters on Truman as a civil libertarian, one on his identification of himself, the other on his relations with Japanese-Americans, the victims during World War II of a major violation of American principles. (more…)

What Happened to Dinosaurs’ Predecessors After Earth’s Largest Extinction 252 Million Years Ago?

Fossil-hunting expeditions to Tanzania, Zambia and Antarctica provide new insights

Predecessors to dinosaurs missed the race to fill habitats emptied when nine out of 10 species disappeared during Earth’s largest mass extinction 252 million years ago.

Or did they?

That thinking was based on fossil records from sites in South Africa and southwest Russia.

It turns out, however, that scientists may have been looking in the wrong places. (more…)

Listening to the Big Bang – in high fidelity

A decade ago, spurred by a question for a fifth-grade science project, University of Washington physicist John Cramer devised an audio recreation of the Big Bang that started our universe nearly 14 billion years ago.

Now, armed with more sophisticated data from a satellite mission observing the cosmic microwave background – a faint glow in the universe that acts as sort of a fossilized fingerprint of the Big Bang – Cramer has produced new recordings that fill in higher frequencies to create a fuller and richer sound. (The sound files run from 20 seconds to a little longer than 8 minutes.) (more…)

Rocket powered by nuclear fusion could send humans to Mars

Human travel to Mars has long been the unachievable dangling carrot for space programs. Now, astronauts could be a step closer to our nearest planetary neighbor through a unique manipulation of nuclear fusion, the same energy that powers the sun and stars.

University of Washington researchers and scientists at a Redmond-based space-propulsion company are building components of a fusion-powered rocket aimed to clear many of the hurdles that block deep space travel, including long times in transit, exorbitant costs and health risks. (more…)

Diversity programs give illusion of corporate fairness, study shows

Diversity training programs lead people to believe that work environments are fair even when given evidence of hiring, promotion or salary inequities, according to new findings by psychologists at the University of Washington and other universities.

The study also revealed that participants, all of whom were white, were less likely to take discrimination complaints seriously against companies who had diversity programs. (more…)

Gene therapy may aid failing hearts

The potential of gene therapy to boost heart muscle function was explored in a recent University of Washington animal study. The findings suggest that it might be possible to use this approach to treat patients whose hearts have been weakened by heart attacks and other heart conditions.

Michael Regnier, UW professor and vice chair of bioengineering, Charles Murry, director of the Center for Cardiovascular Biology and co-director of the Institute for Stem Cell and Regenerative Medicine, and Sarah Nowakowski, a UW graduate student in bioengineering, led the study. The findings appeared online March 25 in the Proceedings of the National Academy of Sciences. (more…)
