Hard as nails!

Most people know that their nails always go soft and bendy when they immerse them in hot water for any length of time. Conversely when you cut your nails they dry up and become hard and brittle.

5. Kaiser Permanente study: Alcohol amount, not type -- wine, beer, liquor -- triggers breast cancer
   09-27-2007 · EurekAlert!
   New Kaiser Permanente study, one of largest individual studies of the effects of alcohol on the risk of breast cancer, concludes it makes no difference whether a woman drinks red wine, white wine, beer or hard liquor, it is the alcohol itself (ethyl alcohol) and the quantity consumed that triggers the onset of cancer. The study of 70,033 multi-ethnic women is the first to look at whether alcohol types makes difference on breast cancer.

   Every advance in memory storage devices presents a new marvel of just how much memory can be squeezed into small spaces. Considering the potential of nanolasers being developed in Sakhrat Khizroev's lab at UC-Riverside, things are about to get a lot smaller. As reported in the latest issue of Technology Review, Khizroev is leading a team exploring lasers so tiny that they point to a future where a 10-terabit hard drive is only one-inch square.

   In a recent survey, experienced reviewers were asked about training they had received in peer review and about other aspects of their background. The results, published in the latest issue of PLoS Medicine, show there are no easily identifiable types of formal training and experience that predict reviewer performance. The implications of these findings are discussed by the PLoS Medicine editors in an editorial to be published in the same issue.
