Physics graduate students Ellen Klein, Sabrina Pasterski, Emma Rosenfeld, Julia Steinberg, and Elana Urbach are year's Harvard recipients of National Science Foundation's Graduate Research Fellowships Program. The Program recognizes and supports outstanding graduate students in NSF-supported science, technology, engineering, and mathematics disciplines who are pursuing research-based Master's and doctoral degrees at accredited United States institutions.

While probing the mystery of how some bacteria move across surfaces, Prof. Howard Berg and researchers in his group, Abhishek Shrivastava and Pushkar Lele, have discovered a kind of rotary motor in the bacterium Flavobacterium johnsoniae.
Fig. 3. (a) Dimensions of tapered photonic crystal fiber (PCF, not to scale). A solid-core PCF is tapered to the desired size over a few millimeters, which gives an adiabatic transition between the transverse modes of the large and small fiber cores. (b) Optical micrograph of tapered PCF with a sealed end.
