Tony Busalacchi (AOSC and ESSIC) has been appointed Chair of the new UMD Council on the Environment, which will operate as an advisory group on research, education, outreach and economic development related to the environment. As chair, Busalacchi will coordinate and oversee strategic efforts to place the University of Maryland at the forefront of environmental and earth system science. Busalacchi will help promote the unique strengths that distinguish UMD from its peers, and develop new partnerships with federal and state government agencies and laboratories, corporations and academic institutions.

Michael Hicks (Computer Science and UMIACS) has been named director of UMD’s Cybersecurity Center (MC2). Hicks' research focuses primarily on developing and evaluating techniques to improve software reliability and security. MC2 was created last year to provide an interdisciplinary, comprehensive approach to educating a new generation of cyber leaders and developing advanced cyber policy and technology. The Center aims to partner with government and industry on advanced research and educational initiatives.

The Department of Physics is holding a Memorial for John S. Toll on Tuesday, December 13, at 4:00 p.m. Toll was the former Chair of the Department, President of the University of Maryland College Park, and the first Chancellor of the University System of Maryland. The Memorial will take place in Room 1410 Physics Building, with refreshments being served prior to the event.  The department would welcome anecdotes and memories of Dr. Toll, so please feel free to send your recollections to phys-chair@umd.edu or Joe Sucher (jsucher@umd.edu). Toll, who passed away on July 15, 2011, was a gifted physicist, a dedicated and highly effective higher education leader and an exemplary public servant.

Book Talk: Image Registration for Remote Sensing

The UMD-NCI Partnership for Cancer Technology workshop was held on November 10, at the National Institutes of Health, Bethesda, Maryland.  The workshop’s goal was to foster interactions between NCI and UMD in biophysics, systems biology, bioengineering, and bioinformatics, and to highlight results from ongoing collaborative projects.  Participating CMNS faculty included Wael Abd-Almageed (UMIACS), Hector Corrada Bravo (Computer Science), Larry Davis (Computer Science and UMIACS), David Fushman (Chemistry & Biochemistry), Michelle Girvan (Physics, IPST & IREAP), Anthony Jose (Cell Biology & Molecular Genetics) Ed Ott (Physics & IREAP) and Arpita Upadhyaya (Physics and IPST).

The Department of Physics held their annual PALS Yard and Bake Sale on November 9, raising over $1,000.00.  This year, PALS donated the monies raised to the PALS Scholarship for Physics Undergraduate Students.  For more information, please contact Tom Gleason, Assistant Director, Undergraduate Office.

The Center for Bioinformatics & Computational Biology (CBCB) has just released version 1.2.0 of the transcript assembly software Cufflinks, a collaborative effort between the Laboratory for Mathematical Computational Biology (Lior Pachter, UC Berkeley), Caltech (Barbara Wold’s Lab) and CBCB.  Cufflinks assembles transcripts, estimates their abundances, and tests for differential expression and regulation in RNA-Seq samples.  It accepts aligned RNA-Seq reads and assembles the alignments into a parsimonious set of transcripts.  Cufflinks then estimates the relative abundances of these transcripts based on how many reads support each one, taking into account biases in library preparation protocols. 

Dennis Bodewits and Stefan Immler (Astronomy) were part of a team studying Asteroid 2005 YU55 during its recent close approach to Earth using NASA's Swift satellite.

In The News

John Weeks (Chemistry and Biochemistry and IPST) was co-editor and also co-authored, with Graduate Student Richard Remsing (Chemistry and Biochemistry, Chemical Physics) and Jocelyn Rodgers (2008 Ph.D. Chemical Physics, advisor John Weeks), one of the articles in a special issue of the Journal of Statistical Physics on water and associated liquids.  The article, on deconstructing classical water models at interfaces and in bulk, focused on the anomalous behavior of the internal pressure and the temperature dependence of the density of bulk water. 

Mikhail Anisimov (IPST and Chemical & Biomolecular Engineering) published a Letter to the Editor in the International Journal of Thermophysics, [DOI 10.1007/s10765-011-1073-0], August 2011 on the occasion of Jan Sengers 80th birthday.  The letter discussed the 1961 breakthrough experiments, conducted by Sengers and Alexander Voronel, which challenged commonly accepted views on critical phenomena in fluids.

Volker Briken and David M. Mosser (Cell Biology & Molecular Genetics and MPRI) published an editorial in the Journal of Leukocyte Biology, November issue, on research conducted by Claire Whyte et al. on the suppressor of cytokine signaling (SOCS) 1 being a key determinant of differential macrophage activation and function.

Jonathan Dinman (Cell Biology and Molecular Genetics) led an interdisciplinary team from UMD, the University of California San Francisco, and the University of Alabama Birmingham, focusing on the role of ribosomal RNA (rRNA) pseudouridylation.  How this most common and evolutionarily conserved modification of rRNA regulates ribosome activity is poorly understood.  Medically, it is important because the rRNA synthase, DKC1, is mutated in X-linked dyskeratosis congenita (X-DC) and Hoyeraal-Hreidarsson (HH) syndrome.  Their findings, published in the November 18 issue of Molecular Cell, uncover specific roles for rRNA pseudouridylation in ribosome-ligand interactions that are conserved in yeast, mouse, and humans.

Alumni News

Sergey Brin (1993 B.S. Computer Science and Mathematics) was quoted in the New York Times, November 13, in an article on Google's top secret lab, Google X.

Judy Che-Casaldo (2011 Ph.D. Behavioral, Ecology, Evolution, and Systematics) with advisor David Inouye (Biology), published, an article in Ecosphere, the new online-only open-access journal of the Ecological Society of America. Using a 35-year dataset from an ongoing study, they described the population dynamics of Frasera speciosa (Gentianaceae), a long-lived monocarpic plant, using matrix projection models, addressed how many years of data are needed to estimate population growth and elasticity values consistently, and examined the effects of mast seeding on demographic parameter estimates. Their results indicated that the demography of F. speciosa is similar to that of other long-lived monocarps without mast seeding, that long datasets may be needed to capture the variation in demographic rates even for stable populations, and that life history stages with low elasticity values can still be very important to population growth. This work was supported by an NSF grant, Drivers and consequences of phenological change at high altitudes, for long-term research
