Researchers have identified a bacterium in field-caught mosquitoes that, when present, stops the development of Plasmodium falciparum, the parasite that causes malaria in humans. According to the study, the Enterobacter bacterium is part of the naturally occurring microbial flora of the mosquito's gut and kills the parasite by producing reactive oxygen species (or free radical molecules).

For Deinococcus radiodurans and other bacteria which are extremely resistant to ionizing radiation, ultraviolet radiation, and desiccation, a mechanistic link exists between resistance, manganese accumulation, and protein protection. We show that ultrafiltered, protein-free preparations of D.

A massive international study is underway to investigate the possible genetic effects of radiation and cancer drug exposures on future generations.

Anhydrobiotic chironomid larvae can withstand prolonged complete desiccation as well as other external stresses including ionizing radiation.

For the first time the morphology of an extended radio source in a binary system formed of a pulsar and a massive star has been determined. In a few such systems, the strong interactions of the stellar winds produces high-energy gamma radiation, up to 10 million times more energetic than visible light. The results show for the first time the effect of the winds colliding and support existing theoretical models of radiation emitted by this type of high-energy binary systems, known as gamma-ray binaries.
