Taxol Bristle Ball: New Delivery Method For Anti-Cancer Drug
Chemists have discovered a way to load dozens of molecules of the anti-cancer drug Taxol onto tiny gold spheres. The result is a ball many times smaller than a living cell that literally bristles with the drug. Researchers hope to use the Taxol bristle ball to deliver large quantities of Taxol directly to cancer cells. Human Testis Harbors HIV-1 In Resident Immune Cells
Researchers have demonstrated HIV replication within resident immune cells of the testis, providing an explanation for the persistence of virus in semen even after effective highly active antiretroviral therapy. The related report by Roulet et al., "Susceptibility of human testis to human immunodeficiency virus-1 infection in situ and in vitro,"appears in the December issue of the American Journal of Pathology. Mother-of-pearl: Classic Beauty And Remarkable Strength
While the shiny material of pearls and abalone shells has long been prized for its iridescence and aesthetic value in jewelry and decorations, scientists admire mother-of-pearl for other physical properties as well. [Scary] Pregnant woman says 'maternal instinct' helped her kill attack
FORT MITCHELL, Ky. - A pregnant woman who killed her attacker said a maternal instinct helped her fight off the woman who investigators believe was after her unborn child."I do believe that I fought harder because it was for my child,"Sarah Brady told ABC's "Good Morning America"in interviews aired Sunday and Monday. "It is a maternal instinct to protect your child to the very end."Katherine Smith, 22, died Thursday after luring Brady to her apartment to pick up a package supposedly delivered to the wrong address. When Smith pulled out a knife and attacked the pregnant woman, Brady fought back, striking Smith on the head with an ash tray and stabbing her three times with her own knife, police said. Brady, 26, said she didn't know Smith before the two met at Smith's apartment and can't be certain why Smith wanted to kill her."I really am not sure what was going through her mind,"Brady told ABC. "The only thing I thought was that she was going to kill me and my child and that is the only thing that ran through my mind." In From the Cold: Following Swans as They Migrate From Russia to Brita

There is more to a grain of dust than meets the eye, at least for astronomers as they attempt to probe deeper into distant galaxies. Until now dust has been a nuisance because it has obscured galaxies, and the stars within them, by absorbing the radiation they emit. But more recently dust has started to present opportunities because it emits radiation itself as a consequence of being heated up by nearby stars.

New Method For Developing Mechanically-reinforced Polymer Nanocomposit
A new method for developing mechanically-reinforced polymer nanocomposites has been developed. The incorporation of nanoparticles into polymers is a design approach that is used in all areas of materials science, according to one of the scientists, adding that in the past, the broad technological utilization of polymer nanocomposites has been stifled by a lack of effective methods to control nanoparticle dispersion in materials. Fewer Fish Discarded After Individual Transferable Quotas Offered
Contradicting previous assumptions, new fisheries research shows that allocating catch among vessels reduces the amount of fish discarded at sea. The study in Canada's British Columbia waters compared so-called individual transferable quotas with a previously used system of trip limits where vessels are only allowed to land a certain quantity of each species every two months.
