Researchers have found that Sulfolobus acidocaldarius exhibits a very high rate of genetic recombination, with 95% of mutations producing recombinants. This suggests an alternative mechanism of DNA repair beyond classical recombination, which may be driven by the microbe's exposure to oxidative stress.

Researchers at Cornell University are working on two projects, COBRA and FIREX, to create a new approach to fusion energy production. COBRA aims to investigate the use of ion beams as an alternative to laser beams for inertial fusion, while FIREX focuses on magnetic fusion and its potential to replace Tokamaks.
