Study Proposes New Ovarian Cancer Targets

Jennifer Ribeiro:

Proteins called TAFs were once thought to be generic cogs in the machinery of gene expression, but in a new study Brown University scientists, including Pathobiology doctoral student Jennifer Ribeiro, propose that they may be important suspects in the progression of ovarian cancer that should not continue to be overlooked.

Graduate International Colloquia Grant

Graduate International Colloquia grants provide an opportunity for students to invite scholars to campus for discussion on a topic of relevance to their study from an international perspective. Up to $5,000 will be awarded for successful proposals. Applications are due April 21, 2014. Learn more and apply.

‘Melbourne Shuffle’ Secures Cloud Data

Dance Steps:

Encryption might not be enough for all that data stored in the cloud. An analysis of usage patterns — which files are accessed and when — can give away secrets as well. Olga Ohrimenko, who recently defended her dissertation at Brown, and other computer scientists here have developed an algorithm to sweep away those digital footprints. It’s a complicated series of dance-like moves they call the Melbourne Shuffle.  The aim is to hide patterns that may emerge as users access data on cloud servers.

A Global Map of Jupiter’s Biggest Moon

An amazing time:

Scientists, including Brown University geologists and students, have completed the first global geological map of Ganymede, Jupiter’s largest moon and the largest in the solar system. The work, led by Geoffrey Collins, a Ph.D. graduate of Brown now a professor at Wheaton College in Massachusetts, took years to complete.

MFA Students Present The Skin of our Teeth

The Skin of our Teeth opens February 27 and runs through March 9 at the Pell Chafee Performance Center. The show is directed by Brown/Trinity Rep MFA student, Taibi Magar. The comedic-drama is set in a time continuum spanning 5,000 years, through the depression, an ice age and a war with the Antrobus family: Mr. and Mrs. Antrobus and their perfect children, Gladys and Henry; and a melodramatic house-maid, Sabina.

Operario Named Dean of Master’s Education

Don Operario is the Graduate School’s first Associate Dean of Master’s Education. This new position is an early initiative of Building on Distinction: A New Plan for Brown, and responds to recommendations by two committees on master’s education.  Dr. Operario is Associate Professor of Public Health and Director of Graduate Studies in the master’s program in Behavioral and Social Sciences Intervention.

Student Research: Signaling Pathway for Sun on the Skin

Molecular Pharmacology & Physiology doctoral student Nicholas Bellono was published in an article with Elena Oancea, assistant professor of medical science and Neuroscience Julia Najera '13 Ph.D. on how the skin's response to the sun’s ultraviolet light is more than just a matter of tanning. Upon exposure, cells called melanocytes produce melanin to protect skin from damage.

Brown Executive Scholars 2014

Nine doctoral and two master's students will explore university administration as part of the fourth cohort of the Brown Executive Scholars Training program. The Graduate School’s 12-week program helps to prepare doctoral and advanced master's students for administrative careers.

New Boron Nanomaterial May be Possible

Unlocking the secrets of the B36 cluster:

Graphene, a sheet of carbon one atom thick, may soon have a new nanomaterial partner. In the lab and on supercomputers, chemists, including doctoral students in Chemistry, Wei-Li Li and Zachary Piazza have determined that a unique arrangement of 36 boron atoms in a flat disc with a hexagonal hole in the middle may be the preferred building blocks for “borophene.” Findings are reported in Nature Communications. Lai-Sheng Wang, professor of Chemistry led the experiments with Li and Piazza.

Image or reality? Leaf study needs photos and lab analysis

Every picture tells a story, but the story digital photos tell about how forests respond to climate change could be incomplete, according to new research. Xi Yang, a graduate student in Geology at Brown and MBL, and other scientists have shown that the peak in forest greenness as captured by digital pictures does not necessarily correspond to direct measures of peak chlorophyll content in leaves, which is an indicator of photosynthesis. The study, which focused on a forest on Martha’s Vineyard, has significant implications for how scientists use digital photos to study forest canopies.
