Focused laser power boosts ion acceleration

An international team of physicists has used carbon nanotubes to enhance the efficiency of laser-driven particle acceleration. This significant advance brings compact sources of ionizing radiation for medical purposes closer ...

Study could change nuclear fuel

The adverse effects of radiation on nuclear fuel could soon be better controlled thanks to research involving UT's College of Engineering.

Space travel is a bit safer than expected

Analysis of data from the MATROSHKA experiment, the first comprehensive measurements of long-term exposure of astronauts to cosmic radiation, has now been completed. This experiment, carried out on board and outside of the ...

In the lab, scientists coax E. coli to resist radiation damage

Capitalizing on the ability of an organism to evolve in response to punishment from a hostile environment, scientists have coaxed the model bacterium Escherichia coli to dramatically resist ionizing radiation and, in the ...

Researchers discover how microbes survive in freezing conditions

Most microbial researchers grow their cells in petri-dishes to study how they respond to stress and damaging conditions. But, with the support of funding from NASA, researchers in LSU's Department of Biological Sciences tried ...
