Under Pressure: Germanium

Washington, D.C. — Although its name may make many people think of flowers, the element germanium is part of a frequently studied group of elements, called IVa, which could have applications for next-generation computer architecture as well as implications for fundamental condensed matter physics.

New research conducted by Xiao-Jia Chen, Viktor Struzhkin, and Ho-kwang (Dave) Mao from Geophysical Laboratory at Carnegie Institution for Science, along with collaborators from China, reveals details of the element’s transitions under pressure. Their results show extraordinary agreement with the predictions of modern condensed matter theory. (more…)

Face Time With a Female Aids Males Bent on Monkey Business

Male monkeys looking for a good time might benefit from spending a bit longer getting to know a potential mate, according to a new study published online in the scientific journal Proceedings of the Royal Society B.

The time males spend around a prospective mate might be the key to detecting subtle sexual signals that show which females are fertile and which are not, according to the study, co-authored by an international team of biologists and psychologists. (more…)

Berkeley Lab Researchers Create Next-Generation Chemical Mapping on the Nanoscale

A pixel is worth a thousand words? Not exactly how the saying goes, but in this case, it holds true: scientists at Berkeley Lab’s Molecular Foundry have pioneered a new chemical mapping method that provides unprecedented insight into materials at the nanoscale. Moving beyond traditional static imaging techniques, which provide a snapshot in time, these new maps will guide researchers in deciphering molecular chemistry and interactions at the nanoscale—critical for artificial photosynthesis, biofuels production and light-harvesting applications such as solar cells.

“This new technique allows us to capture very high-resolution images of nanomaterials with a huge amount of physical and chemical information at each pixel,” says Alexander Weber-Bargioni, a postdoctoral scholar in the Imaging and Manipulation of Nanostructures Facility at the Foundry. “Usually when you take an image, you just get a picture of what this material looks like, but nothing more. With our method, we can now gain information about the functionality of a nanostructure with rich detail.” (more…)

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…)
