Researchers at the Georgia Institute of Technology have released a study supporting the findings of several studies last year linking an increase in the strength of hurricanes around the world to a global increase in sea surface temperature. The new study strengthens the link between the increase in hurricane intensity and the increase in tropical sea surface temperature. It found that while factors such as wind shear do affect the intensity of individual storms or storm seasons, they don't account for the global 35-year increase in the number of the most intense hurricanes. The study appears online in the March 16 edition of Science Express at www.scienceexpress.org |

Researchers at the Georgia Institute of Technology and the University of California, San Francisco, have found an even more effective and safer way to detect and kill cancer cells. By changing the shapes of gold nanospheres into cylindrical gold nanorods, they can detect malignant tumors hidden deeper under the skin, like breast cancer, and selectively destroy them with lasers only half as powerful as before, without harming the healthy cells. The method, which allows for a safer, deeper penetrating noninvasive cancer treatment, has just appeared in the Journal of the American Chemical Society, volume 128. |

Studying fish, like this ocean sulfish, scientists are revealing the link between evolution and a species' genome. 'As a general rule, more complex organisms, like humans, have larger genomes than less complex ones,' said J. Todd Streelman, assistant professor in the School of Biology at the Georgia Institute of Technology and co-author of the study. 'You might think this means that animals with the largest genomes are the most complex, and for the most part that would be right. But it's not always true. There are some species of frogs and some amoeba that have much larger genomes than humans.' |

Combination products, devices that include a combination of drug, biological and device components, are expected to be the next big thing in biomedical devices. An example of a combination product is a tissue-engineered device that combines living cells with a polymer scaffold. When implanted into a patient, the device can replace or restore damaged tissue or organ function. While the response of the body to each component is well known, considerably less is known about how their new union may affect the body's reaction to a combination device. |

Years ago, when Uzi Landman and his colleagues set out to uncover some of the rules that govern why a non-reactive metal like gold acts as a catalyst when it is in nanoclusters only a few atoms in size, they didn't sit down in a lab with the precious metal. Instead, they ran computer simulations and discovered that gold is a very effective catalyst when it is in clusters of eight to two dozen atoms. They also found that electrical charging of gold is crucial to its catalytic capabilities. Six years later, the team has verified their earlier predictions experimentally, and they stand ready to further explore environmental effects on catalysis. |

How is it that we can look at a door and accidentally call it a window or call a shovel a rake? When people mislabel objects, they often blame themselves for rushing their words or not paying attention. But research at the Georgia Institute of Technology, published in the December issue of Psychological Science, suggests the mistakes may have less to do with concentration than previously thought. The findings provide an insight into how the brain organizes speech and suggests that when the tongue slips, the eyes may be the best window into a speaker's intent. |

It's no secret that life in the 21st century moves at a rapid pace. Human inventions such as the Internet, mobile phones and fiber optic cable have increased the speed of communication, making it possible for someone to be virtually in two places at once. But can humans speed up the rate of one of nature's most basic and slowest processes, evolution? A study by J. Todd Streelman, new assistant professor of biology at the Georgia Institute of Technology suggests that humans may have sped up the evolutionary clock for one species of fish. |
