New symptom may help ID sleep apnea in older women


Obstructive sleep apnea may be underdiagnosed in postmenopausal women. A new study strongly associates the condition’s traditional risk factors with nocturnal enuresis (bedwetting), suggesting that it may be an additional screening factor for doctors to consider.

Rose to address 2015 Opening Convocation

The 252nd Academic Year

Tricia Rose, professor of Africana studies and director of the Center for the Study of Race and Ethnicity in America, will deliver the 252nd Opening Convocation address to the campus community, including undergraduate, graduate, and medical school students who are beginning their studies at Brown this fall. The ceremony begins at 4 p.m. Tuesday, Sept.

Brown Welcomes International Graduate Students

International orientation kicked off on campus, with up to 300 incoming doctoral and master's students participating. Thirty-nine percent of the incoming graduate students are from outside the U.S. Students come from 49 countries, with the most coming from China, India, Germany, Canada and Italy. The two-day orientation for international graduate students is co-sponsored by the Graduate School, the Office of Student & Scholar Services and the Office of the Vice President for Campus Life & Student Services. 

Pigments, Organelles Persist in Fossil Feathers

A study provides multiple lines of new evidence that pigments and the microbodies that produce them can remain evident in a dinosaur fossil. In the journal Scientific Reports, an international team of paleontologists, including doctoral student in Ecology and Evolutionary Biology Ryan Carney, relates the distinct chemical signature of animal pigment with physical evidence of melanosome organelles in the fossilized feathers of Anchiornis huxleyi, a bird-like dinosaur that died about 150 million years ago in China.

Pigments, organelles persist in fossil feathers


An international team of researchers has found direct chemical evidence that the fossilized remains of a bird-like dinosaur still harbor melanosomes and the pigment they produced. Their study reinforces the idea that scientists can discern the coloration of long-lost animals.
