College freshmen under the age of 20 at several colleges in the southeastern U.S. were almost 70 percent more likely to test positive for chlamydia than students between 20 and 24 years of age, according to findings to be presented on May 9 by Adelbert James, PhD, MPH, senior associate in the Department of Gynecology and Obstetrics at Emory University School of Medicine. Dr. James will present results of his data analysis at the 2006 National STD Prevention Conference in Jacksonville, Fla. His effort is the first regional evaluation of chlamydia prevalence on college campuses.
The screening, conducted by student health centers in April 2004, included 789 students (263 freshmen), who were screened voluntarily for chlamydia at 10 colleges in Alabama, Georgia and Mississippi. Due in part to the participation of several historically black colleges, the majority of participants were African American (80.2 percent), with more than half of the students screened being female (57 percent). The average age of participants was 21.7.
While chlamydia prevalence in all students tested was 9.7 percent, prevalence among the 263 freshmen was 13 percent. Dr. James, who directs the Centers for Disease Control and Prevention (CDC)-sponsored Region IV Infertility Prevention Project, says it is critical for student health centers to provide chlamydia screening and treatment services. He says it is just as important to educate college freshmen and other students about STD risks and prevention strategies.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
