Oksana Ostroverkhova has been chosen by the American Physical Society as their Woman Physicist of the Month for May 2017. The Woman Physicist of the Month is a program of the APS’s Committee on the Status of Women in Physics (CSWP). It highlights exceptional female physicists, recognizing their positive impact other individuals’ lives and careers.

Randy Milstein gave a talk on May 10 about the solar eclipse at an OMSI Science Pub at OSU. The full talk is now available online at:
Physics graduate student Carly Fengel shows a Timber Ridge Elementary School student the beautiful spectral lines of hydrogen, helium, argon and neon lamps. When viewed through diffraction grating glasses, the various wavelengths of light are split apart, revealing a unique signature for each gas. “So we could tell what stars are made of!” remarked the student.
Family Science Nights have been a yearly staple in Corvallis schools for more than a decade, but May 16 was only the second one for Timber Ridge School, a combined middle and elementary school serving a rural area on the northern edge of Albany. About 200 students of all ages attended the event, with middle-school students acting as guides and selling snacks as a fundraiser.
In addition to volunteers from the physics department, OSU was represented by other departments, including the College of Veterinary Medicine, the College of Earth, Ocean, and Atmospheric Sciences, and the School of Nuclear Science and Engineering. Non-departmental groups also showed up, such as the Dairy Club, Geology Club, and Fisheries and Wildlife Club. For the first time, nursing students from Linn-Benton Community College made an appearance, rounding out the science offerings with tables focusing on exercise, vital signs, CPR, and hand-washing.
Other physics demos included classics like levitating ping-pong balls with a hair dryer and the ever-popular hovercraft. As usual, the line for the hovercraft rarely dropped below a dozen students, continuing to draw a crowd to the end of the hall throughout the evening. Many were eager to learn how the hovercraft worked and several times kids remarked: “I want to make one!”
(Prof. Ethan Minot explains the design of the hovercraft)
As the last Family Science Night of the school year, this event ended the semester on a high note, with several new groups and a new physics demonstration. Both volunteers and families will be looking forward to next year’s school outreach events.
A big thank you to the physics student volunteers Evan Peters, Garrett Jepson, and Carly Fengel.

A paper just published in Nature Communications by the Single-Molecule Biophysics Laboratory of Assistant Professor Weihong Qiu reports an unexpected mechanical property of a “motor” protein that offers new insights into how motor proteins help build and maintain the mitotic spindle, the American football-shaped macromolecular structures that animal and fungi cells depend on to ensure accurate chromosome segregation during cell division. Located inside cells, motor proteins are tiny molecular machines that convert chemical energy into mechanical work. They interact with train-track-like structures called microtubules to transport cargos or exert forces.
In this study, Qiu and colleagues focused on a particular motor protein called KlpA, and used a high-sensitivity microscopy method to directly visualize the motion of individual KlpA molecules on microtubules. The Qiu team shows that, while all other KlpA-like motor proteins are believed to move in only one direction on the microtubule track, KlpA has a “reverse” gear that allows it to go in different directions. This enables KlpA to behave differently in when it is operating at different locations within the mitotic spindle. This research may open the door to understand the similar KlpA-like motor proteins in mammals that are implicated in cancer cell proliferation. Understanding the design principle underlying the bidirectional motion of KlpA may also guide the engineering of motor protein-based molecular devices for targeting drug delivery in a controllable manner.
