Oligotrophy and pelagic marine bacteria: facts and fiction

Asbestos: facts and fiction.

Asbestos: Facts and Fiction I appreciate the opportunity to address the omissions, inaccuracies, and innuendos in the position paper by David P. Rall, "Media and Science: Harmless Dioxin, Benign CFCs, and Good Asbestos" (EHP 102:10). Unfortunately, Rail not only misinterprets the conclusions of our 1990 Science article by Mossman et al. (1) but he fails to mention the database, scientific panel...

Leprosy: Facts and Fiction

Antagonistic interactions among marine pelagic bacteria.

Recent studies suggest that bacterial abundance and species diversity in the ocean's water column are variable at the millimeter scale, apparently in response to the small-scale heterogeneity in the distribution of organic matter. We hypothesized that bacterium-bacterium antagonistic interactions may contribute to variations in community structure at the microscale. We examined each of the 86 i...

Teething: facts and fiction.

Artificial muscle: facts and fiction.

Mechanical devices are sought to support insufficient or paralysed striated muscles including the failing heart. Nickel-titanium alloys (nitinol) present the following two properties: (i) super-elasticity, and (ii) the potential to assume different crystal structures depending on temperature and/or stress. Starting from the martensite state nitinol is able to resume the austenite form (state of...
