One of my pet peeves is the passive voice. And it is a thing that almost everyone does in their writing*. The passive voice is, apparently, what many scientists think sound appropriate/formal. Or something. For example:
It was found that the effects of gene x on (blah blah) were significant.
As compared to:
We found that gene x had a significant effect on (blah blah).
Do you see what I did there?
Now, this may be a common problem when you are first starting to write about science. In fact, many people (including me) have a tendency to write like this. But please PLEASE go through and remove the passive voice from your writing before you make someone else read it. If you are lucky, there will be someone that can beat this out of you before it is too late. Sadly, this is not always the case. In fact, I have heard of the horrifying situation where a senior author reverts nice, active sentences into a passive voice! I don't know what advice to offer you if you find yourself in this position. I mean, I guess you could run screaming. That is probably the best option. Really, I can only hope you all avoid such a horrible fate. Good luck!
*heck, some folks even do this when they are talking. WTF????
