Boosting armor for nuclear-waste eating microbes

A microbe developed to clean up nuclear waste and patented by a Michigan State University researcher has just been improved.

In earlier research, Gemma Reguera, MSU microbiologist, identified that Geobacter bacteria’s tiny conductive hair-like appendages, or pili, did the yeoman’s share of remediation. By increasing the strength of the pili nanowires, she improved their ability to clean up uranium and other toxic wastes. (more…)

Fukushima Lesson: Prepare for Unanticipated Nuclear Accidents

ANN ARBOR, Mich.— A year after the crisis at Japan’s Fukushima Daiichi nuclear power plant, scientists and engineers remain largely in the dark when it comes to fundamental knowledge about how nuclear fuels behave under extreme conditions, according to a University of Michigan nuclear waste expert and his colleagues.

In a review article in this week’s edition of the journal Science, U-M’s Rodney Ewing and two colleagues call for an ambitious, long-term national research program to study how nuclear fuels behave under the extreme conditions present during core-melt events like those that occurred at Fukushima following the March 11, 2011, magnitude 9.0 earthquake and tsunami.

Microbes Generate Electricity While Cleaning Up Nuclear Waste

EAST LANSING, Mich. — Researchers at Michigan State University have unraveled the mystery of how microbes generate electricity while cleaning up nuclear waste and other toxic metals.

Details of the process, which can be improved and patented, are published in the current issue of the Proceedings of the National Academy of Sciences. The implications could eventually benefit sites forever changed by nuclear contamination, said Gemma Reguera, MSU microbiologist. (more…)

Technological Advances and the Dangers of Nuclear Energy

The successive and increasingly frequent occurrences of environmental disasters caused by human activities deserves our utmost attention. Leading us to necessarily suspect that we should have credible and foolproof trials before accepting assertions regarding existing technologies. 

The most striking example is the disaster caused by the explosion and sinking of the Deepwater Horizon oil exploration platform by British Petroleum (BP) which happened last April 20, and which day after day has reached catastrophic proportions.
