Science News Officer
Ali Sundermier covers physics, astronomy, chemistry, and math in the School of Arts and Sciences. She also works closely with the School of Engineering and Applied Science to assist in covering computer and information science, materials science and engineering, mechanical engineering and applied mechanics, bioengineering, and chemical and biomolecular engineering.
A maverick among chemists
Madeleine Joullie, the first woman to join Penn’s chemistry faculty, was also the University’s first affirmative action officer, which she says is the most important thing she’s done.
Using statistics to uncover the truth about individual cells
Researchers at Penn have developed a better method for interpreting data from single-cell RNA sequencing technologies.
Making complex 3-D surfaces with 2-D sheets
Using liquid crystal elastomer, researchers are able to transform 2-dimensional rubber-like sheets into malleable, three-dimensional shapes, with a precise amount of control for various shape sequences.
Looking to the stars
This year's Simons Observatory Collaboration conference included a community star party that consisted of a panel, a mixer with astronomers, and stargazing.
Sharing space to support ‘better science’
Across disciplines, Penn researchers in the Computational Neuroscience Initiative put their heads together to better understand the brain.
Harnessing DNA tricks to boost nanosensors
Researchers have found a way to increase the sensitivity of graphene sensors using a trick of DNA engineering. The sensors might one day be used to monitor and treat HIV.
Detecting distant stars: Q&A with Jose Maria Diego and Jesus Vega
While observing an exploding star in a galaxy cluster billions of light-years away, two visiting scholars noticed a curious speck of light in their images. The light was from an ancient star more than 9 billion years ago, the most distant star ever detected.
Immune system function in the microgravity of space
Researchers from the School of Engineering and Applied Science and the Perelman School of Medicine are developing a technology to better understand how microgravity negatively affects immune system function.
Science and politics: a Q&A with Molly Sheehan
The School of Engineering and Applied Science postdoc researcher discusses what fascinates her about science, her unique path in science and technology, and the role scientists should play in political office.
An innovative approach to better energy storage
A Penn/Drexel research team has engineered a way to manipulate nanomaterials to stand up vertically on a scale that has potential for industrial applications.
