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…)

UCLA physicists’ technique for cooling molecules may be a stepping stone to quantum computing

The next generation of computers promises far greater power and faster processing speeds than today’s silicon-based based machines. These “quantum computers” — so called because they would harness the unique quantum mechanical properties of atomic particles — could draw their computing power from a collection of super-cooled molecules.

But chilling molecules to a fraction of a degree above absolute zero, the temperature at which they can be manipulated to store and transmit data, has proven to be a difficult challenge for scientists. (more…)

In last great age of warmth, CO2 at work — but hardly alone

Warming patterns during Earth’s last period of prolonged global warmth differed dramatically from modern temperature patterns, according to new research by a Yale University scientist and colleagues. Cloud feedbacks, ocean mixing, or other dynamic factors must have played a greater role in Pliocene warming than commonly recognized, the scientists argue, and these must be accounted for in order to make meaningful predictions about Earth’s future climate.

Microsoft BizSpark startup uses Windows Azure to put keyword search control into the hands of humans rather than algorithms.

REDMOND, Wash. — April 3, 2013 — One of the biggest fears for website developers is that their visitors click an internal search button on the site, can’t find what they’re looking for and leave frustrated. Because every failed search can mean a lost opportunity for business owners, elicit was founded to help people find what they are looking for within a website.

The founders of elicit are all serial entrepreneurs who met when working together at various startups. Brothers Eric and Adam Heneghan are the co-founders of Giant Step, a digital marketing firm; Jeff Froom is an application and interaction developer; and Chip Aubry is a software architecture expert. While working at an interactive marketing agency, they formed the idea for elicit based on feedback from customers. (more…)

The UA Libraries has just made 150 years of regionally published newspapers documenting the voice of Mexican and Mexican American communities digitally available for the first time.

A new digital collection at the University of Arizona Libraries makes accessible more than 150 years of news coverage documenting the voice of the Mexican and Mexican American community.

Curated, researched and digitized by librarians and archivists, in consultation with UA professors, the collection features 20 significant Mexican and Mexican American publications, many in Spanish. (more…)

All living organisms rely on iron as an essential nutrient. In the ocean, iron’s abundance or scarcity means all the difference as it fuels the growth of plankton, the base of the ocean’s food web. (more…)

The origins of laughter

We know the benefits of laughter on health. But why do we laugh? What are the evolutionary origins of laughter and humour? Steven Légaré has asked these questions and has made them the subject of his master’s thesis, which he recently submitted to the Université de Montréal’s Department of Anthropology.

“Science provides few answers to these questions other than in psychology and neuroscience. From the perspective of anthropology, laughter and humour are often overlooked. However, it is a serious subject,” says the recent graduate. (more…)
