| Body's Circadian Rhythm Tightly Entwined With Blood Sugar Control
October 6, 2009 at 8:00 pm
|
| Scientists have long struggled to understand the body's biological clock. Its tick-tock wakes us up, reminds us to eat and tells us when to go to bed. But what sets that circadian rhythm? New research now shows that daily fluctuations in powerful hormones called glucocorticoids directly synchronize the biological clock as an integral part of our mechanism for regulating blood sugar. |
| Just A Yoctosecond: Shortest Flashes From Ultra-hot Matter
October 6, 2009 at 8:00 pm
|
| High-energy heavy ion collisions can be a source of light flashes of a few yoctoseconds duration (a septillionth of a second, 10^-24 s) -- the time that light needs to traverse an atomic nucleus. This is shown in calculations of the light emission of so-called quark-gluon plasmas, which are created in such collisions for extremely short periods of time. Under certain conditions, double flashes are created, which could be utilized in the future to visualize the dynamics of atomic nuclei. |

October 6, 2009 at 5:00 pm
|
| A vaccine to treat cocaine dependence appears to reduce use of the drug in a subgroup of individuals who attain high anti-cocaine antibody levels in response, according to a new report. However, only 38 percent of vaccinated individuals produced high enough antibody levels and those who did maintained them for only two months. |
| Solving The Period Problem: Researchers Develop Sanitary Pads From Local, Organic Materials
October 6, 2009 at 5:00 pm
|
| For most women, their "time of the month" is seen as a hindrance to daily life. In impoverished and developing countries, however, monthly periods are a major cause for concern. The lack of affordable, quality sanitary pads results in females missing up to 50 days of school annually -- thereby compromising their educational and professional potential. Researchers are helping to combat the problem by designing affordable pads made from natural, available materials that will allow for local production and sale. |

| Black Rat Does Not Bother Mediterranean Seabirds
October 6, 2009 at 5:00 am
|
| Human activities have meant invasive species have been able to populate parts of the world to which they are not native and alter biodiversity there over thousands of years. Now, an international team of scientists has studied the impact of the black rat on bird populations on Mediterranean islands. Despite the rat's environmental impact, only the tiny European storm petrel has been affected over time by its enforced cohabitation with the rat. |
