Scientist-in-training Summer Praetorius has an unusual skill—she is really, really good at spotting four-leaf clovers (Trifolium repens L.). A single gene causes the normally three-leafed clover to produce a fourth, supposedly lucky, leaf. As it turns out, good science depends on both close observation—a skill Praetorius uses to spot tiny shelled animals called foraminifera—and a little bit of luck. Ari Daniel Shapiro explains.

Favella (fah-vell-a) - one of the tintinnid ciliates. Tintinnids are predominantly marine ciliates and are normally located within a lorica. The shape, sculpting and attaching material are used to distinguish the different taxa. Favella has a cone-shaped lorica, without attached material, with a small degree of sculpting of the anterior end of the lorica. The cell is attached to the lorica by a strand of cytoplasm. The cilia form an anterior wreath of membranelles, and the activity of these both draws the cells forward and allows them to collect particles of food - mostly small algae. Phase contrast.
