DNA Prefers to Dive Head First Into Nanopores

A preference for diving head first :

Graduate student Mirna Mihovilivic observed single molecules of DNA being drawn through nanopores by electrical current and figured out why they most often travel head first. The research, published in the journal Physical Review Letters, looks at the dynamics of how DNA molecules are captured by solid-state nanopores, tiny holes that soon may help sequence DNA at lightning speed.

Student Research on HIV Disclosure Rates in Ethiopia

Ayalu Reda, a graduate student in sociology, is the lead author on a paper recently published in AIDS Care about HIV disclosure rates in Ethiopia, where more than 1.2 million people are thought to be HIV-positive. Reda's research reveals that many HIV-positive patients do not disclose their status to their spouse, siblings, or sometimes to anyone and often travel far distances to receive treatment.

Kreinik onstage at Trinity Rep

Barrie Kreinik, an M.F.A. student in the Brown/Trinity program, is one of two actors starring in Trinity Repertory Company’s current production, The How and the Why, which runs through Dec. 30, 2012.

Trinity describes the play as a “funny, gripping new play ...

Nagy awarded EPA STAR for research

The U.S. Environmental Protection Agency this week recognized the research of Rachel Chelsea Nagy, a doctoral student in ecology and evolutionary biology, with a Science to Achieve Results (STAR) award. Nagy studies the complex interplay between farming and forest management in Brazil, where the environmental services of the forests include storing carbon that would otherwise contribute to global warming. “The Brazilian economy is growing rapidly and the country must balance economic development with conservation and restoration of tropical forests,” Nagy said.

Postdoc Research: Streaks on Mars May be Caused by Flowing Water

Edgard Rivera-Valentin:

Edgard Rivera-Valentin, a postdoc in Geological Sciences, was co-author of the research that suggests the melting of frozen salty water on Mars last year may be the cause of the dark streaks on the planet. The were spotted by NASA's Mars Reconnaissance Orbiter spacecraft. Rivera-Valentin worked with researchers from other universities to model the behavior of the water-and-salt mixtures to figure out how the liquid could flow on the frigid surface of Mars.

Student Research: How Silver Turns People Blue

Too much of a good thing :

Ingesting too much silver can cause argyria, a rare condition in which patients’ skin turns a striking shade of grayish blue. Graduate students in chemistry Jingyu Liu and Zhongying Wang and Professor Robert Hurt and other researchers have discovered how this happens. 

Student Research: Bullies More Likely to Have Mental Illnesses

Dr. Frances Turcotte-Benedict:

Public health graduate student Dr. Frances Turcotte-Benedict recently presented at the national conference of the American Association of Pediatrics. She reported that children with diagnosed mental illness are three times more likely to bully than children without disorders. For a biostatistics class project, Turcotte-Benedict and her co-authors reviewed data on nearly 64,000 children from the 2007 National Survey of Children’s Health. Parents in the survey identified 15.2 percent of children as bullies.
