Explaining why the universe can be transparent

Two papers published by an assistant professor at the University of California, Riverside and several collaborators explain why the universe has enough energy to become transparent.

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 ...

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 ...

'Sideline quasars' helped to stifle early galaxy formation

University of Colorado Boulder astronomers targeting one of the brightest quasars glowing in the universe some 11 billion years ago say "sideline quasars" likely teamed up with it to heat abundant helium gas billions of years ...
