The last of Mars’ liquid waters flowed about 2 billion years ago

By now, there’s plenty of evidence that Mars had a watery past, and more data is coming in all the time. But that evidence doesn’t necessarily give us a complete picture of Mars’ past. Was the red planet covered in watery oceans, or was most of the water trapped as ice, with erratic seasonal melting?

This week, two researchers at Caltech—Ellen Leask and Bethany Ehlmann—helped provide a clearer picture of Mars’ past by figuring out the likely behavior of the last liquid water on Mars and determining when it stopped flowing. Their secret was tracing salt deposits on the Martian surface.

Follow the salt

There are many different salts we’ve detected on the Martian surface, but the ones of interest here are chlorides (which probably include the sodium chloride of table salt). These are especially informative because they are the salts most readily soluble in water. So if there’s any water around, these chloride salts would be dissolved in it. Any deposits of these salts currently present on the surface of Mars, then, were put there as the last water in that region of the planet dried out.

Cisco security breach hits corporate servers that ran unpatched software

Cisco security breach hits corporate servers that ran unpatched software

Six servers Cisco uses to provide a virtual networking service were compromised by hackers who exploited critical flaws contained in unpatched versions the open source software service relies on, the company disclosed on Thursday.

Got updates?

The May 7 compromise hit six Cisco servers that provide backend connectivity to the Virtual Internet Routing Lab Personal Edition (VIRL-PE), a Cisco service that lets customers design and test network topologies without having to deploy actual equipment. Both the VIRL-PE and a related service, Cisco Modeling Labs Corporate Edition, incorporate the Salt management framework, which contained a pair of bugs that, when combined, was critical. The vulnerabilities became public on April 30.

Cisco deployed the vulnerable servers on May 7, and they were compromised the same day. Cisco took them down and remediated them, also on May 7. The servers were:
