Q: What does this Kernel Panic report mean? What can I do?

Hi,

I've had my MacBook (Late 2013 Retina 15" MacBook Pro) crash a few times, resulting in a kernel panic. I know a fair share about software, programming, website but I know absolutely nothing about crashing, etc.. All I know is that it crashed very suddenly, resulting in a grey screen talling me a Kernel Panic had occurred.

I was hoping someone could make anything out from this? I saw current thread was 'Skype' but I wasn't using it at the time, it was just in the background. This has happened before and I may not have been using it then. (It's not set to open at boot.) I was using a weather app ("Living Earth") at the moment it crashed but I only installed that yesterday and it's crashed before then.

Here's the Kernel Panic Report from /Library/Logs/DiagnosticReports.

As I say, it's happened a few times before (twice recently but also a while ago).

I'd be really thankful if anyone could share some light on this.
