Why E. coli move faster in syrup-like fluids than in water
Wed, 25 Nov 2015 11:32:36 EST
Swimming in a pool of syrup would be difficult for most people, but for bacteria like E. coli, it's easier than swimming in water. Scientists have known for decades that these cells move faster and farther in viscoelastic fluids, such as the saliva, mucus, and other bodily fluids they are likely to call home, but didn't understand why. New findings could inform disease models and treatments, or even help design microscopic swimming robots.
Chemical design made easier

A metal-free process has been developed for the rapid synthesis of elusive small-molecule catalysts that promise to speed the making of novel chemicals, including drugs.
Atom-sized craters make a catalyst much more active

Bombarding and stretching an important industrial catalyst opens up tiny holes on its surface where atoms can attach and react, greatly increasing its activity as a promoter of chemical reactions, according to a new study.
New, inexpensive way to clean water from oil sands production found
Mon, 23 Nov 2015 20:23:38 EST
A process to remove contaminants from oil sands wastewater has been found by researchers, which uses only sunlight and nanoparticles. They report that the process is more effective and inexpensive than conventional treatment methods.
Oily waste with natural radionuclides: Stimulates or inhibits soil bacterial community?
Mon, 23 Nov 2015 10:18:51 EST
Researchers have revealed both structural and functional changes of the microbial community resistant to and able to decompose oily wastes in soil. The experiment was dedicated to measuring carbon dioxide efflux, microbial biomass, and community structure for 120 d after application of radioactive oily wastes to the soil at the ratio 1:4. Both waste and soil samples were collected in Tatarstan, Russia.
