Seeing Original Research here on STEEM is obviously fantastic, there's no praise from me who's not a member of #steemstem that would seem reasonable here so I'll just shut up about that now and say: GOOD!

Onto less important things:
For a moment I had to wonder if having a banner, like the image of the encapsulated cell cluster below (but in better quality, obviously)

Would make for a better attention-grabber in the feed -- who doesn't love cell close-ups! But then the value of having the video there in the header is probably greater -- so many articles posted under #steemstem have static banners so a video would naturally stand out. But perhaps adding a relevenat image banner to your next video would not hurt.
