Engineered microbes grow in the dark 05/19/2013
Scientists have engineered a strain of photosynthetic cyanobacteria to grow without the need for light.
Insecticides lead to starvation of aquatic organisms 05/16/2013
Neonicotinoid insecticides have adverse effects not only on bees but also on freshwater invertebrates. Exposure to low but constant concentrations of these substances – which are highly soluble in water – has lethal effects on these aquatic organisms.
Low-grade cotton offers more ecologically-friendly way to clean oil spills 05/16/2013
When it comes to cleaning up the next massive crude oil spill, one of the best and most eco-friendly solutions for the job may be low-grade cotton from West Texas.
Natural 'keystone molecules' punch over their weight in ecosystems 05/16/2013
Ecosystems are disproportionately influenced by "keystone molecules" that have powerful behavioral effects and contribute to ecosystem structure, according to a new general theory. The chemicals can each fill a variety of functions and affect multiple species. The actions of four keystone molecules are described, three of them toxins.
Cotton offers a new ecologically friendly way to clean up oil spills 05/15/2013
With the Deepwater Horizon disaster emphasizing the need for better ways of cleaning up oil spills, scientists are reporting that unprocessed, raw cotton may be an ideal, ecologically friendly answer, with an amazing ability to sop up oil.
Nanoscavengers could usher in next generation water purification 05/15/2013
A new synthetic nanoparticle could disinfect, depollute, and desalinate contaminated water and then get removed magnetically. This improves upon existing technologies through ultraresponsiveness to magnetism.
Groundwater unaffected by shale gas production in Arkansas 05/15/2013
A new study finds no evidence of groundwater contamination from shale gas production in Arkansas.
Making gold green: New non-toxic method for mining gold 05/14/2013
Scientists have struck gold in the laboratory. They have discovered an inexpensive and environmentally benign method that uses simple cornstarch -- instead of cyanide -- to isolate gold from raw materials in a selective manner. This green method extracts gold from crude sources and leaves behind other metals that are often found mixed together with the crude gold.
