Deflating Scientific Fallacies

Yale neurologist Steven Novella populates his podcasts and blogs with aliens, ghosts and creationists for a single purpose: to help resurrect the lost art of scientific thinking.

“I am interested in how otherwise intelligent people can get things so horribly wrong,” says Novella. In the process of answering that question he created the website Skeptics Guide to the Universe — which, with 150,000 listeners a week, is one of the 10 most popular science sites on the internet.

Oxygen Sensor Invention Could Benefit Fisheries to Breweries

East Lansing, Mich — Monitoring oxygen levels in water has applications for oil spills, fish farming, brewing beer and more – and a professor at Michigan State University is poised to help supply that need.

The concept of oxygen sensors isn’t new. The challenge, however, has been manufacturing one that can withstand fluctuations in temperature, salinity, carbon dioxide, phosphates and biological wastes. Ruby Ghosh, associate professor of physics, was able to overcome those obstacles as well as build one that provides real-time data and is relatively inexpensive. (more…)

Watch Your Language! of Course–But How Do We Actually Do That?

Nothing seems more automatic than speech. We produce an estimated 150 words a minute, and make a mistake only about once every 1,000 words. We stay on track, saying what we intend to, even when other words distract us—from the radio, say, or a road sign we pass while driving.

An upcoming study in Psychological Science, a journal of the Association for Psychological Science, shows for the first time why we so rarely speak those irrelevant words: We have a “verbal self-monitor” between the mental production of speech and the actual uttering of words that catches any irrelevant items coming from outside of the speaker.

Research Shows Not Only the Fittest Survive

Darwin’s notion that only the fittest survive has been called into question by new research published in Nature.

A collaboration between the Universities of Exeter and Bath in the UK, with a group from San Diego State University in the US, challenges our current understanding of evolution by showing that biodiversity may evolve where previously thought impossible.

The work represents a new approach to studying evolution that may eventually lead to a better understanding of the diversity of bacteria that cause human diseases. (more…)

NASA Airborne Radar Set to Image Hawaiian Volcano

PASADENA, Calif. – The Kilauea volcano that recently erupted on the Big Island of Hawaii will be the target for a NASA study to help scientists better understand processes occurring under Earth’s surface.

A NASA Gulfstream-III aircraft equipped with a synthetic aperture radar developed by NASA’s Jet Propulsion Laboratory in Pasadena, Calif., is scheduled to depart Sunday, April 3, from the Dryden Aircraft Operations Facility in Palmdale, Calif., to the Big Island for a nine-day mission. (more…)

Novel Nanowires Boost Fuel Cell Efficiency

Fuel cells have been touted as a cleaner solution to tomorrow’s energy needs, with potential applications in everything from cars to computers.

But one reason fuel cells aren’t already more widespread is their lack of endurance. Over time, the catalysts used even in today’s state-of-the-art fuels cells break down, inhibiting the chemical reaction that converts fuel into electricity. In addition, current technology relies on small particles coated with the catalyst; however, the particles’ limited surface area means only a fraction of the catalyst is available at any given time.
