Biology postdoc awarded National Institutes of Health fellowship
Researchers have demonstrated proof-of-principle of a protein-based intranasal vaccine platform, called SpyCage, that could eventually help to prevent infection and transmission of respiratory viruses, like SARS-CoV-2. Image shows an illustration of the SpyCage vaccine platform, on right, decorated with a portion of the spike protein from SARS-CoV-2, next to an illustration of the virus.

On the right, the nanoparticles, shown as black dots, find the basal-like breast cancer cells in yellow and deliver the gene-editing tools. The disintegrating cell demonstrates the destructive power of the therapy delivered by the nanoparticle. Credit: Provided by Dipanjan Pan. All Rights Reserved.

A new study led by researchers at Penn State has uncovered how a widespread bacteria called Wolbachia and a virus that it carries can cause sterility in male insects by hijacking their sperm messenger molecules — tagged with red fluorescence in this image of Drosophila testes. These findings could improve techniques to control populations of agricultural pests and insects that carry diseases like Zika and dengue to humans. Credit: Rupinder Kaur / Penn State.

New research shows how lung cancer cells can survive better and exhibit less cell damage when exposed to cigarette smoke in cell culture experiments compared to non-cancerous lung cells. Image shows non-cancerous lung cells (left) and lung cancer cells (right), subjected to the same concentration of cigarette smoke condensate. Non-cancerous cells have more pronounced protein aggregation granules (shown with an arrow), stained by Proteostat, a type of cell damage that can eventually lead to cell death.
