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.

Cilia use different motors for different tasks

Cilia — short, hair-like fibers — are widely present in nature. Single-celled paramecia use one set of cilia for locomotion and another set to sweep nutrients into their oral grooves. Researchers at Brown, including Physics graduate student Il-yong Jung, have discovered that those two cilia sets operate at different speeds when the viscosity of the environment changes. That suggests different molecular motors driving them, which could help explain how cilia have come to be used for so many different tasks in nature.

Student Research: Pigment Found in Ancient Reptiles

An international team of researchers including biology graduate student Ryan Carney reports in Nature Jan. 8, 2014, that they have found pigmentation in the skin of three fossilized marine reptiles. Because an animal’s coloration often has an important role in how it lives, the direct chemical evidence of the pigment eumelanin that they found offers new clues about the evolution and biology of aquatic animals over a span of tens of millions of years.
