Could Martian atmospheric samples teach us more about the red planet than surface samples?
NASA is actively working to return surface samples from Mars in the next few years, which they hope will help us better understand whether ancient life once existed on the red planet's surface billions of years ago. But what about atmospheric samples.....»»

Investigating nematode-microbe interactions in lab-simulated decomposed beetle environments
Beneath the surface, bacterivorous nematodes are key players in the nutrient cycle, consuming bacteria that decompose organic matter. Traditionally, these nematodes are studied in laboratory environments where isolated bacterial strains are used to m.....»»
Marsquakes could reveal whether liquid water exists underground on red planet
If liquid water exists today on Mars, it may be too deep underground to detect with traditional methods used on Earth. But listening to earthquakes that occur on Mars—or marsquakes—could offer a new tool in the search, according to a team led by.....»»
