Renaissance for magnetotactic bacteria in astrobiology

Magnetotactic bacteria can form magnetofossils like magnetic nanocrystals as observed in the Martian meteorite ALH84001, which held a special place in the field of astrobiology primarily in the early 90s. While the flourishing ...

NASA finds ancient organic material, mysterious methane on Mars

NASA's Curiosity rover has found new evidence preserved in rocks on Mars that suggests the planet could have supported ancient life, as well as new evidence in the Martian atmosphere that relates to the search for current ...

Martian glass: Window into possible past life?

Researchers from Brown University have used satellite data to detect deposits of glass within impact craters on Mars. Though formed in the searing heat of a violent impact, the glasses just might provide a delicate window ...

Organic carbon from Mars, but not biological

(Phys.org) -- Molecules containing large chains of carbon and hydrogen--the building blocks of all life on Earth--have been the targets of missions to Mars from Viking to the present day. While these molecules have previously ...

Drilling Down into Mars

(PhysOrg.com) -- NASA's Phoenix lander revealed water ice mere inches beneath the martian surface, and chemical evidence from the landing site strongly hints that the region is habitable. But learning whether there is life ...

Mars was Wet, but was it Warm?

Mars is frozen today, but when it was young there may have been liquid water on its surface. What does the latest evidence indicate about the ancient martian climate? Understanding the past environment of Mars can help future ...

Surprising insights about debris flows on Mars

The period that liquid water was present on the surface of Mars may have been shorter than previously thought. Channel landforms called gullies, previously thought to be formed exclusively by liquid water, can also be formed ...
