Exposure to chronic, low dose radiation -- the conditions present in deep space -- causes neural and behavioral impairments in mice, researchers report in eNeuro.

A boiling point of 5900 degrees Celsius and diamond-like hardness in combination with carbon: tungsten is the heaviest metal, yet has biological functions - especially in heat-loving microorganisms.

The International Space Station, like all human habitats in space, has a nagging mold problem. Astronauts on the ISS spend hours every week cleaning the inside of the station's walls to prevent mold from becoming a health problem.

Earth's magnetic field shields space station crew from much of the radiation that can damage the DNA in our cells and lead to serious health problems.

Simulations with animal models meant to mirror galactic cosmic radiation exposure to astronauts are raising red flags for investigators at Georgetown University Medical Center (GUMC) about the health of astronauts during long voyages, such as to Mars.

Intense radiation could strip away the ozone layer of Earth-like planets around other stars and render them uninhabitable, according to a new study led by Dr Eike Guenther of the Thueringer Observatory in Germany.

The energetic particle environment on the Martian surface is influenced by solar and heliospheric modulation and changes in the local atmospheric pressure (or column depth).

We present an overview of sources of biologically relevant astrophysical radiation and effects of that radiation on organisms and their habitats. We consider both electromagnetic and particle radiation, with an emphasis on ionizing radiation and ultraviolet light, all of which can impact organisms directly as well as indirectly through modifications of their habitats.

A planet having protective ozone within the collimated beam of a Gamma Ray Burst (GRB) may suffer ozone depletion, potentially causing a mass extinction event to existing life on a planet's surface and oceans.

A new water bear protein can protect the DNA of human cultured cells from otherwise lethal amounts of radiation damage, say a group of Japanese researchers, providing part of the answer to why tardigrades can live in deadly conditions.
