Using Viruses to Make Better Batteries

Written by , on March 10, 2014

Lithium-air batteries hold the promise of drastically increasing power per battery weight. However, achieving this requires solving a number of challenges, including the need to develop better, more durable materials for the batteries' electrodes and improving the number of charging-discharging cycles the batteries can withstand. MIT researchers believe that a combination of genetic engineering and […]  Read more »

Milking Bacteria for Biofuel

Written by , on October 14, 2012

A team of scientists at MIT have genetically altered a common soil bacteria called Ralstonia eutropha into producing biofuel and expelling biofuel into its growing medium instead of retaining it within its body. Normally, biofuel is extracted from bacteria by crushing it; the new process is analagous to milking. The biofuel, isobutanol, can be blended […]  Read more »

Genetic Engineering

Farmers have been genetically modifying plants and animals for thousands of years – producing hybrids through traditional breeding methods and then selecting out those with favourable characteristics. But these traditional methods, like cross-fertilisation, can take thousands of trials over many years to obtain the required characteristic and weed out undesirable ones. Genetic engineering elimates the […]  Read more »
