Unveiling the life of archaea in sediments: Diversity, metabolic potentials, and ecological roles
Archaea exhibit extensive diversity and ubiquitous distribution in sediments across a range of habitats, from terrestrial inland to deep‐sea environments, including hot springs, salt lakes, freshwater lakes, rivers, mangroves, estuaries, coastal areas, seafloor sediments, cold seeps, and hydrothermal vents.

To escape from hosts after completing their life cycle, bacteriophages often use endolysins, which degrade bacterial peptidoglycan. While mesophilic phages have been extensively studied, their thermophilic counterparts are not well characterized.

Health Impacts of Traditional Medicines and Bio-prospecting: A World Scenario Accentuating Bhutan's Perspective [PDF]
Life without natural products is unimaginable. It has provided mankind with oxygen, water, fire, food, clothing, shelter and medicine. Its public health impact is considerably high, especially of traditional medicines and nature-based modern drugs.

Microbial Fuel Cells Applied to the Metabolically-Based Detection of Extraterrestrial Life [PDF]
Since the 1970's, when the Viking spacecrafts carried out experiments aimed to the detection of microbial metabolism on the surface of Mars, the search for nonspecific methods to detect life in situ has been one of the goals of astrobiology. It is usually required that the methodology can detect life independently from its composition or form, and that

Rainfall after drought induces enormous dynamics in microbial growth (potential soil carbon storage) and respiration (determining carbon loss), affecting the ecosystem carbon budget. We investigated how legacies of drought and warming affected microbial functional and structural responses after drought, using soils from tropical cropland and forest ...

Detection of Endolithes Using Infrared Spectroscopy [PDF]
On Earth, the Dry Valleys of Antarctica provide the closest martian-like environment for the study of extremophiles. Colonies of bacteries are protected from the freezing temperatures, the drought and UV light. They represent almost half of the biomass of those regions. Due to there resilience, endolithes are one possible model of martian biota.

About Exobiology: The Case for Dwarf K Stars [PDF]
One of the most fundamental topics of exobiology concerns the identification of stars with environments consistent with life. Although it is believed that most types of main-sequence stars might be able to support life, particularly extremophiles, special requirements appear to be necessary for the development and sustainability of advanced life forms.

Cometary panspermia explains the red rain of Kerala [PDF]
Red coloured rain occurred in many places of Kerala in India during July to September 2001 due to the mixing of huge quantity of microscopic red cells in the rainwater. Considering its correlation with a meteor airbust event, this phenomenon raised an extraordinary question whether the cells are extraterrestrial.

Searching for Life on Habitable Planets and Moons [PDF]
Earth is the only known inhabited planet in the universe to date. However, advancements in the fields of astrobiology and observational astronomy, and the discovery of large varieties of extremophiles with extraordinary capablities to thrive the in the harshest environments on Earth, have led to speculation that life may be thriving on many of the ...
