Real evidence that can be seen and observed and tested and studied, like real science should. No crap like missing links that have been proven to be frauds or fruit flys that produce fruit flys. Real evidence that a real dog can swim in the ocean for a while and turn into a real whale, or something along that lines. Where is the tons of evidence?

I know it's kind of gross, but I have this water bottle on my dresser in my dorm that's been there for about a month. It has about an inch of water in it, which I used 3-4 weeks ago (it was clean) to rinse out the little measuring cup for my cough syrup (I had a sinus infection and a bad cough). Being lazy, I then poured the water back into the bottle instead of going to the bathroom to dump it in the sink. So now, about a month later, I was going to throw the bottle out but noticed that, at the bottom of the little pool of pinkish water, there is a white, fuzzy-looking growth. It is almost a perfect sphere except for the bottom part, which is completely flat. It looks like a little ball of cotton or something. It is about 1.5cm in diameter and 1cm tall. It is light pink, from the cough syrup probably, and is darker pink in the center. I'm guessing it's some kind of mold? Is it from the cough syrup? Or maybe bacteria from my infection? Any insight would be appreciated.

Hi!

What makes a stem cell pluripotent? Is it just the fact that it was taken from an already differentiated cell and it cannot be reversed?

Is it not possible for a stem cell to produce, say, an oocyte, so that really, it's totipotent? (Because a fertilized egg is the ultimate totipotent cell)

Or am I taking this too far... like, is the difference b/w toti- & pluripotency only *relatively* short term?

Thanks!
