Specific Results

1. Coating Steel With a Layer of Diamond (ScienceDaily.com)
   "A surface treatment of steel with boron was also found to result in a good intermediate layer, even on stainless steel. An advantage of this treatment is that the difference in expansion between diamond and steel is gradually dissipated. After the production of diamond at about 600 oC, the steel contracts much more than the diamond coating and the coating can become detached as a result of this. A treatment with boron gives the external surface of the steel an expansion coefficient more or less comparable to that of diamond. This effect gradually decreases from the surface of the steel inwards." 02-08

2. Cloud Forest Animals (CloudForestAlive.org)
   Provides pictures and interesting descriptions of animals that inhabit the cloud forests of Central America and the Mesoamerican Biological Corridor. Includes, for example, the spider wasp, guan, olingo, toucanet, howler monkeys, gray fox, viper, fruit bats, bananaquit, cyclosa spider, solitaire, skink, spectacled owl, ant lion, thrush, tink frog, nocternal katydids, chunk-headed snake, anole, trogon, spiny lizard, oropendolas, marine toad, coati, two-toed sloth, mottled owl, army ants, deer, redstarts, and screech owl. 2-01

3. Solar Window Film (Scientific American)
   "Help may soon be available in the form of a smart film that can block heat--but not light--from the sun. Recent findings indicate that the window coating can reduce room heating by as much as 50 percent." 8-04

4. Disposable Plastic Water Bottles Harmful? (U.S. News)
   " 'Awwk!' That was my first reaction when I read a recent E-mail about new dangers lurking in my disposable water bottle, the one with a No. 1 recycling code stamped on the bottom that sits on my desk waiting to be refilled. There's a new study from Germany out today that tested the water in those bottles and found estrogenlike compounds, most likely leaching out from the plastic. These water bottles don't contain the notorious chemical bisphenol A, which is found in hard water bottles, baby bottles, and the plastic coatings of metal cans. (Studies of BPA indicate that high exposures could increase the risk of reproductive health problems and possibly breast, prostate, and ovarian cancers, which is why six leading baby bottle makers last week decided to ban it from their products.) The soft bottles do, though, contain other estrogenlike compounds, still unidentified, that could have the same harmful effects as BPA." 03-09

5. Cranberry Juice Protects Teeth (Time Magazine)
   "Oral biologists coated a synthetic tooth-enamel-like substance with cranberry juice and applied cavity-causing microbes, Streptococcus mutans—which metabolize sugars into acids that cause tooth decay—and found, after seven months of study, that cranberry juice acts like a non-stick coating that made it 80% effective in protecting teeth. Bacteria couldn't get a grip on tooth surfaces to construct a haven of plaque from which to attack teeth."
   
   "The cranberry's non-stick, protective properties might be why the berry has been shown to be effective against urinary tract infections and, in another study, helped inactivate intestinal viruses: bacteria and viruses can’t adhere to surfaces to infect them. But before you reach for the leftover cranberry sauce or go rinsing with cranberry juice, remember that sugar contributes to dental decay and more study needs to be done on what might make cranberry an effective agent in keeping teeth strong." 11-05
