Posted: 15 Sep 2008 07:00 PM CDT There are numerous examples in our daily language of metaphors which make a connection between cold temperatures and emotions such as loneliness, despair and sadness. We are taught at a young age that metaphors are meant to be descriptive and are not supposed to be taken literally. However, recent studies suggest that these metaphors are more than just fancy literary devices and that there is a psychological basis for linking cold with feelings of social isolation.  |
| First Picture Of Likely Planet Around Sun-like Star Posted: 15 Sep 2008 04:00 PM CDT Astronomers have unveiled what is likely the first picture of a planet around a normal star similar to the Sun. Scientists used the Gemini North telescope on Mauna Kea in Hawai'i to take images of the young star, which lies about 500 light-years from Earth, and a candidate companion of that star. They also obtained spectra to confirm the nature of the companion, which has a mass about eight times that of Jupiter, and lies roughly 330 times the Earth-Sun distance away from its star. The parent star is similar in mass to the Sun, but is much younger.  |
| Posted: 15 Sep 2008 04:00 PM CDT Nearly every child who receives an antipsychotic medicine is first prescribed a second-generation, or "atypical" drugs. However, there has never been evidence that these drugs are more effective or safer than the older, first-generation medications. Now a UNC Chapel Hill School of Medicine study suggests that first-generation drugs are as effective as the newer ones and should be used as a first line of therapy in some children.  |
