Extremophiles are organisms capable of adjust, survive or thrive in hostile habitats that were
previously thought to be adverse or lethal for life. Chile gathers a wide range of extreme …

Microbial taxa from every major biological lineage have been detected in Earth's upper
atmosphere. The goal of this review is to communicate (1) relevant astrobiology questions …

The hypothesis called “panspermia” proposes an interplanetary transfer of life. Experiments
have exposed extremophilic organisms to outer space to test microbe survivability and the …

The causal agent of Kawasaki disease (KD) remains unknown after more than 40 years of
intensive research. The number of cases continues to rise in many parts of the world and KD …

Bioaerosol transport in the atmosphere disperses microbial species between continents,
affects human and plant health, and may influence hydrologic cycling. However, there have …

Spores of Bacillus subtilis were exposed to a series of stratosphere simulations. In total, five
distinct treatments measured the effect of reduced pressure, low temperature, high …

The Earth's atmosphere is an extremely large and sparse environment which is quite
challenging for the survival of microorganisms. We have long wondered about the limits to …

From birds to bacteria, airborne organisms face substantial anthropogenic impacts. The
airspace provides essential habitat for thousands of species, some of which spend most of …

High‐altitude Andean lakes (HAAL) are a treasure chest for microbiological research in
South America. Their indigenous microbial communities are exposed to extremely high UV …

The high-altitude atmosphere is a harsh environment with extremely low temperatures, low
pressure, and high UV irradiation. For this reason, it has been proposed as an analogue for …
