Unlocking the mystery of pollen tube guidance

Pollen tube guidance towards the ovule is an important step for fertilization in flowering plants. In order for this to happen, a pollen tube attractant peptide LURE guides the pollen tube precisely to the ovule. Plant biologists have succeeded in analyzing for the first time, the crystal structure of LURE bound to its receptor protein PRK6. https://www.sciencedaily.com/releases/2017/12/171229095136.htm

Should we store all posted pictures? on This site's dev's official community

Oct. 28, 2017, 12:14 a.m.

Todays browsers have been warning users when there's non https in links.
when a user post a picture, it just makes img html tags towards that image file. Sometimes they are not https and the browser throws annoying messages.
So I was thinking if it would be nice to don't let foreign links on the page and store all shared photos here.

What do you think?
