Virtual lecture to explore the importance of maintaining healthy ecosystems

On March 25, Erika Ganda, an assistant professor in Penn State’s Department of Animal Science, will discuss via Zoom how microbes in animals, people and the environment are interconnected through a concept known as “One Health.” The lecture is part of the Penn State Alumni Association's Virtual Speaker Series.

A new study has described a potential mechanism that could help explain why some proteins refold in a different pattern than expected. The research showed that a type of misfolding, called non-covalent lasso entanglement, in which the proteins incorrectly intertwine their segments, can occur and create a barrier to the normal folding process. The image shows the native folded structure of the protein phosphoglycerate kinase (PGK) on the left and one of the misfolded PGK structures predicted in this study on the right, with the entangled regions highlighted in red and blue.

Protein accidentally lassos itself, helping explain unusual refolding behavior

New study demonstrates a potential protein misfolding mechanism that could solve a decades-old mystery of why some proteins refold in a different pattern than expected.

Tunnel-building virus: How Zika transmits from mother to fetus

A team of researchers from Penn State and Baylor College of Medicine found that the Zika virus builds tiny tunnels, called tunneling nanotubes, to stealthily transport material needed to infect nearby cells, including in placental cells.

Graduate students to present their journeys in science

Graduate students Nazifa Tabassum and Katie Yan are this year's I AM STEM contest winners. They will serve at this year's keynote speakers for ENVISION on Saturday, March 29, where they will share their experiences in STEM and provide advice to middle school and high school students eager to get involved as scientists.

Plant biologist awarded the Masatoshi Nei Innovation Prize in Biology

Sarah Assmann, Waller Professor of Plant Biology at Penn State, has been awarded the Masatoshi Nei Innovation Prize in Biology. The award was established through a generous gift from Masatoshi Nei, professor emeritus of biology at Penn State; Laura Carnell, professor of biology at Temple University; and Nei’s wife, Nobuko Nei. The prize is intended to recognize a preeminent scientist who is on the faculty at Penn State, is an innovator in their field, and has achieved outstanding scientific research and leadership in the biological sciences.

Analyzing genetic ‘signatures’ may give insight into what stresses wild bees

A new method of examining gene expression patterns called landscape transcriptomics may help pinpoint what causes bumble bees stress and could eventually give insight into why bee populations are declining overall.
