UWM Physicists Apply Infrared Technology for Early Malaria Detection
University of Wisconsin - Milwaukee (UWM)Professor of Physics, Carol Hirschmugl, and postdoctoral researcher, Eric Mattson, are part of an international team attempting to diagnose malaria infected cells. A paper recently published in the journal 'Analyst' describes the application of unique imaging equipment created by Dr. Hirschmugl for investigating strategies to obtain early diagnosis of the disease. The malaria parasite Plasmodium falciparum causes on of the most deadly diseases in humans, with a mortality rate of almost 1.2 million people a year. The process implemented by Hirschmugl and Mattson utilizes a special detector called a Focal Plane Array (FPA) that is sensitive to the infrared spectrum as part of Dr. Hirschmugl's Infrared Environment Imaging (IRENI) system. Testing of the early malaria detection procedure was performed at the Synchrotron Radiation Center (SRC) at UW-Madison. Although currently limited by the need for a synchrotron-based light source Hirschmugl hopes to see commercial technology improve and allow this technique to be widely used in the future. Further details are presented in the title link.

UWM Physicist Collaborates on Identification of the Coldest, Faintest White Dwarf
University of Wisconsin - Milwaukee Assistant Professor of Physics, David Kaplan, is part of an international astronomical team studying a recently discovered double star system. The system consists of a superdense spinning neutron star which is emitting millisecond pulses of radiation (a pulsar) and a remarkably cool white dwarf companion. The team applied Einstein's theory of general relativity, which first predicted that light (and radio waves) slows in the gravitational field of a massive object. Dr. Kaplan and his colleagues used the Green Bank Telescope (GBT) to study this 11 billion-year-old system. The team next searched for visible and infrared evidence of the companion, using the Southern Astrophysical Research (SOAR) telescope in Chile, and the Keck telescope in Hawaii. Even though the "cool companion" is not visible evidence of its circular orbit indicates that it is a white dwarf rather than a neutron star which would have an elliptical orbit. A paper describing this system was recently published in the Astrophysical Journal. Further details are presented in the title link.

International Conference on Women in Physics names UWM Physics Assistant Research Professor as a Delegate
University of Wisconsin - Milwaukee (UWM) Physics department Assistant Research Professor and American Physical Society Blewett Fellow, Dr. Sujatha Sampath, has been named as a delegate to the upcoming 5th IUPAP International Conference on Women in Physics. The International Union of Pure and Applied Physics (IUPAP) has long recognized a particular need to foster the participation of women in physics and is sponsoring the 2014 conference to be hosted at the Wilfrid Laurier University located in Waterloo, Canada. The conference gathers delegates from around the world to showcase scientific work in all areas of physics and to promote the participation of women in physics. At UWM Dr. Sampath pursues research in the experimental aspects of Molecular and Materials Physics.

UWM Physicists Collaborate in Two Papers on the Topological Insulator Bi2Se3
University of Wisconsin - Milwaukee (UWM) condensed-matter physicists Dr. Lian Li, Dr. Michael Weinert, and other members of the department, recently published two papers on the properties of the topological insulator Bi2Se3. The research reports were published in Nature Nanotechnology (March 2014) and Nature Physics (April 2014 cover story) Topological insulators form a new quantum phase of matter that is distinct from metals and semiconductors. These materials are expected to produce new functionalities and enable insights into complex phenomena in many scientific areas.

UWM Physicist Helps Write First Paper in Inaugural Volume of New Journal in High Energy Physics
A team of high energy physicists, including UWM Physics Professor Luis Anchordoqui,were recently asked to write the first paper for the inaugural issue of the "Journal of High Energy Physics". The first two volumes of the journal are scheduled to appear in May of 2014 but the paper already appears on the internet.
The paper is a review article concerned with the observation and analysis of neutrinos as unique astronomical messengers. The study of these particles is important both in neutrino astrophysics and the study of new physics in the electroweak sector. Furthermore, observation of high energy neutrinos coming from the Sun may assist scientists trying to understand the properties of "dark matter" in the universe.

UWM Manfred Olson Planetarium Director Chosen for NASA Airborne Astronomy Program
University of Wisconsin - Milwaukee Manfred Olson Planetarium director, Jean Creighton, has been chosen to participate in NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) program. A local high school teacher, (Kathy Gustavson), and Jean will form one of twelve two-person teams who have been selected as SOFIA Airborne Astronomy Ambassadors. Each team will be paired with a professional astronomer to observe first-hand how airborne infrared astronomy is conducted and bring their experiences back to their classrooms.
SOFIA is a highly modified Boeing 747SP jetliner fitted with a 100-inch (2.5 meter) effective diameter telescope. The aircraft flies at altitudes between 39,000 and 45,000 feet (12-14 kilometers), above the water vapor in the Earth's atmosphere, and collects data in the infrared spectrum.
