In a new study, Stanford researchers have strongly bolstered the theory that a lack of oxygen in Earth's oceans contributed to a devastating die-off approximately 444 million years ago. The new results further indicate that these anoxic (little- to no-oxygen) conditions lasted over 3 million years - significantly longer than similar biodiversity-crushing spells in our planet's history.Beyond deepening understandings of ancient mass extinction events, the findings have relevance for today: Global climate change is contributing to declining oxygen levels in the open ocean and coastal waters,...…In a new study, Stanford researchers have strongly bolstered the theory that a lack of oxygen in Earth's oceans contributed to a devastating die-off approximately 444 million years ago.

New research indicates river delta deposits within Mars’ Jezero crater – the destination of NASA’ Perseverance rover on the Red Planet – formed over time scales that promoted habitability and enhanced preservation of evidence.Undulating streaks of land visible from space reveal rivers once coursed across the Martian surface – but for how long did the water flow? Enough time to record evidence of ancient life, according to a new Stanford study.Scientists have speculated that the Jezero crater on Mars – the site of the next NASA rover mission to the Red Planet – could be a good place to look...…New research indicates river delta deposits within Mars’ Jezero crater – the destination of NASA’ Perseverance rover on the Red Planet – formed over time scales that promoted habitability and enhanced preservation of evidence.Undulating streaks of land visible from space reveal rivers once coursed across the Martian surface – but for how long did the water flow?
