Bioprinting Breast Cancer Tumor

By Adrienne Berard

Researchers at Penn State have successfully 3D bioprinted breast cancer tumors and treated them in a breakthrough study to better understand the disease that is one of the leading causes of mortality worldwide.

A scientific first, the achievement lays the foundation for precision fabrication of tumor models. The advancement will enable future study and development of anti-cancer therapies without the use of "in vivo" — or "in animal" — experimentation.

Some everyday materials have memories, and now they can be erased

Materials have memory

By Gail McCormick

Some solid materials have a memory of how they have previously been stretched out, which impacts how they respond to these kinds of deformations in the future. A new Penn State study lends insight into memory formation in the foams and emulsions common in food products and pharmaceuticals and provides a new method to erase this memory, which could guide how materials are prepared for future use.
