From one gene switch, many possible outcomes

A team of researchers led by Aman Husbands of the School of Arts & Sciences has uncovered surprising ways transcription factors—the genetic switches for genes—regulate plant development, revealing how subtle changes in a lipid-binding region can dramatically alter gene regulation.

Novel coupled nanopore platform offers greater precision for detecting molecules

An interdisciplinary team of researchers from Penn have created the first ever reusable coupled nanopore platform for detecting and guiding molecules, findings could pave the way for much improved DNA sequencing and molecule identification.
A climate expert’s return to Penn
Portrait of Jen Wilcox

Jen Wilcox has returned to the Kleinman Center for Energy Policy at the Stuart Weitzman School of Design and to the School of Engineering and Applied Science following three years in at the U.S. Department of Energy, where she served in the Biden Administration as the principal deputy assistant secretary for the Office of Fossil Energy and Carbon Management.

Does heat travel differently in tight spaces?
Green-tinted image showing thermal plumes in a Hele-Shaw cell, illustrating heat transfer in confined spaces.

Hugo Ulloa and Daisuke Noto of the School of Arts & Sciences have unearthed findings that address long-standing mysteries in the mechanics of fluids in confined, tight spaces: how their boundaries affect heat as it emanates from one place and dissipates throughout the space. The image above is a lab-scale hydrothermal system modeled utilizing a Hele-Shaw cell of 10 cm tall, 20 cm long and 4 mm gap. The interior of the Hele-Shaw cell is filled with degassed, deionized water heated from the bottom and cooled from above. A green laser sheet crosses the middle plane of the cell to visualize the motions of micro-scale particles seeded on the water, allowing researchers to estimate the fluid velocity and temperature.
