Science certainly never killed philosophy. Many would argue that they complement each other.
Keeping up with the "latest in the cutting edge" in philosophy is probably very difficult.
How do you define "cutting edge"? There could be philosophers who have some brilliant ideas but haven't been discovered by academia. It's possible that academia is deliberately ignoring or snubbing others, as philosophy has been infiltrated by propagandists, similar to science.
On top of that, philosophy is such a vast, complex field, how can any one person get a handle on what's already been philosophized?
I find it more convenient to break philosophy up into various topics (e.g. truth, lying or justice), some of which interest me more than others. I then focus on one topic and try to learn what philosophers have written about that particular topic. What are the most recent books and articles about that topic? Are there any individuals who are considered experts on it?
But keeping tabs on the whole of philosophy is more daunting. I doubt that there's any reputable philosophy clearinghouse, nor would I likely trust anyone who claims to be such a source. You can monitor websites as well as the news to get some idea of what's going on. I just learned about an anonymous stoic philosopher who has garnered 65,000 fans on Twitter.
In other news, I learned that philosophers are taking a hard look at black holes - something they can hardly do without the help of science. And Kim Kardashian is apparently enrolled in law school. I don't know how that showed up on a search for news about philosophy, but it sounds like another kind of black hole to me.
