Aluminum Oxide Nanoparticles Hinder Growth: Study

(A study involving tobacco plants exposed to varying levels of aluminum oxide nanoparticles reveals troubling growth issues. -ed)

Effects of Aluminum Oxide Nanoparticles on the Growth, Development, and microRNA Expression of Tobacco (Nicotiana tabacum)

"In this experiment, aluminum oxide nanoparticles affect the amount of leaves three week old tobacco seedlings have"


Nanoparticles are a class of newly emerging environmental pollutions. To date, few experiments have been conducted to investigate the effect nanoparticles may have on plant growth and development. It is important to study the effects nanoparticles have on plants because they are stationary organisms that cannot move away from environmental stresses like animals can, therefore they must overcome these stresses by molecular routes such as altering gene expression.  (Image of aluminum oxide nanoparticles at left from US Research Nanomaterials Inc.)
After three weeks of culture, the seedlings grown in the presence of aluminum oxide nanoparticles showed an obvious decrease through the visualization of the root lengths, leaf count, and biomasses of the seedlings.

Climate Engineer States His Case on Nanoparticles 

(David Keith is emerging as a leading proponent of "geoengineering" the planet, here's an excerpt of his reasoning on using nanoparticles over sulfer particles in the chemical soup that has become our skies -ed.)

Aerosols could be injected into the upper atmosphere to engineer the climate by scattering incident sunlight so as to produce a cooling tendency that may mitigate the risks posed by the accumulation of greenhouse gases. 

Analysis of climate engineering has focused on sulfate aerosols. Here I examine the possibility that engineered nanoparticles could exploit  photophoretic forces, enabling more control over particle distribution and lifetime than is possible with sulfates, perhaps allowing climate engineering to be accomplished with fewer side effects. 

The use of electrostatic or magnetic materials enables a class of photophoretic forces not found in nature. Photophoretic levitation could loft particles above the stratosphere, reducing their capacity to interfere with ozone chemistry; and, by increasing particle lifetimes, it would reduce the need for continual replenishment of the aerosol.

(from Wikipedia:  Description of above diagram:  The electrostatic field (lines with arrows) of a nearby positive charge (+)causes the mobile charges in conductive objects to separate due to electrostatic induction. Negative charges (blue) are attracted and move to the surface of the object facing the external charge. Positive charges (red) are repelled and move to the surface facing away.)

David Keith As Super Hero

(Note from editor:  David Keith, noted professor of applied physics at Harvard, was on the TEDS NPR program on August 9, 2013, and here's a video where he extolls (with deliberate humor) the benefits of 'climate engineering')
