Ruga mechanics of creasing

Origins and uses of wrinkles, creases, folds

Three ruga states and how they form:
New research into the origins of — and structural differences between — wrinkles, creases, and folds could have applications in many fields, from flexible electronic devices to dermatology to flexible sheets that become sticky when stretched. Findings from a Brown University research group appear in Proceedings of the Royal Society A.


Cry analyzer seeks clues to babies’ health

Cry, baby:
Researchers at Brown University and Women & Infants Hospital have developed a new tool that analyzes the cries of babies, searching for clues to potential health or developmental problems. Slight variations in cries, mostly imperceptible to the human ear, can be a “window into the brain” that could allow for early intervention.

Engineers Mehves Tangun '13 and Jonathan Hills '13 among 2013 VFA fellows

Venture for America returns to Brown

“Take some risks and do something different”:
Venture for America has returned to campus for its second five-week summer training camp. The nonprofit’s class of 68 fellows — up from 40 last year — participates in lectures and exercises meant to prepare them for two-year apprenticeships. Venture for America places fellows at early stage and start-up companies in economically challenged cities with the hope that they will stay and eventually start their own companies. Among the 68 fellows are five Brown alumni, including two engineering alumni, Mehves Tangun and Jonathan Hills, and Moss Amer, who concentrated in Business, Organizations, and Entreprenuership (BEO). 

Rough edges at the nanoscale

Jagged graphene can slice into cell membranes

Rough edges at the nanoscale:
A collaboration of biologists, engineers, and material scientists at Brown University has found that jagged edges of graphene can easily pierce cell membranes, allowing graphene to enter the cell and disrupt normal function. Understanding the mechanical forces of nanotoxicity should help engineers design safer materials at the nanoscale.
