Gene Profiling Can Single Out The Worst Cases Of Multiple Myeloma And
Multiple myeloma patients vary widely in how they respond to treatment, but now researchers have identified a small subset of genes whose activity could predict high-risk cases and potentially guide therapy in the future. Sperm Injection: Male-factor Infertility Technique Surging
A national study reveals that intracytoplasmic sperm injection, an assisted reproductive technology used to treat male-factor infertility, has increased dramatically in the United States since 1995 while the proportion of patients receiving treatment for male-factor infertility has remained stable. Works of Art: The Costume Institute
"The world-renowned Costume Institute at the Metropolitan Museum [in New York] possesses more than 75,000 costumes and accessories from seven centuries and five continents."This site provides a brief overview of the collection and images of 50 specially selected items. Also includes images and information about exhibits on topics such as fashion and furniture in the 18th century, rock-and-roll style, and "Extreme Beauty: The Body Transformed"(about items such as corsets, bustles, and lotus shoes). Guide to Non-Dairy "Milks"
Guide to choosing alternatives to dairy milk, such as soy milk, rice milk, and almond milk. Discusses nutritional content (including calcium and Vitamin D), choices for children, cooking with milk substitutes, and related topics. Specific brands and products mentioned may have changed, but the document provides good guidelines for choosing alternatives to milk for specific uses and needs. Written by a registered dietician for the Vegetarian Resource Group. Why certain drug combinations backfire
Researchers have discovered why certain combinations of drugs are actually less effective together than one of the drugs alone. Specifically, antibiotic drugs that block DNA replication work poorly with drugs that block protein synthesis. This is because the latter group corrects one of the weaknesses that the first group exploits. Synthetic Viruses Aiming At Cancer Cells
Cancer and many other life-threatening diseases are caused by genetic defects. These so-called mutations prevent the affected genes from fulfilling their normal functions. Gene therapies try to make use of viruses for the import of healthy genes into cells where they can replace their defective counterparts. Newer approaches employ synthetic viruses which pose a lesser threat of pathogenic side effects. These "custom-made"molecular vehicles are designed in a way that allows them to bind almost exclusively to affected cells and leave out healthy tissue. Electrical Exercise System Gives Paralysis Sufferers Power To Recover
A new system uses electrical signals to stimulate movement in arm muscles where function has been lost. Earth's Core More Complex Than Thought: Atoms Form Layers Of Spiral Pa
It is hard to know what is going on over 3000 kilometers beneath our feet, but until recently scientists were fairly confident that they understood the way the iron atoms in the Earth's core packed together. However, new research has overturned conventional thinking and revealed that the structure of the core is not as straightforward as was once thought. Google Print
A searchable archive of the full texts of books scanned from publishers and libraries. The site includes a discussion of what portions of materials are available for books that may still be under copyright protection: "you'll only see snippets of text directly around your search term. This snippet view is designed to help users ... make a decision about whether to go find a physical copy of the book." Tight-knit Family: Even Microbes Favor Their Own Kin
New research in this week's issue of Nature finds that even the simplest of social creatures -- single-celled amoebae -- have the ability not only to recognize their own family members but also to selectively discriminate in favor of them. The study by Rice University biologists provides further proof of the surprisingly sophisticated social behavior of microbes, which have been shown to exhibit levels of cooperation more typically associated with animals.
