Scientists uncover the genetic pathway that colors bumble bee stripes

While most people in the U.S. may think of bumble bees as the standard yellow and black variety, there are an estimated 260 bee species that sport about 400 different color patterns. One reason many people associate bumble bees with distinct colors is because evolution can influence multiple bee species to share similar color patterns in specific geographic regions, which scientists call mimicry.

Preparing for potential pandemics is focus of new federal grant to Penn State

Researchers at Penn State have received a grant from the National Institute of Allergy and Infectious Diseases to study H7N9 with a goal of developing new and fundamental knowledge of virus mutations that could indicate the potential for transmissibility in humans. 

Actinium is a radioactive element that could revolutionize cancer medicine but its chemistry has thus far remained elusive. LLNL and Penn State researchers developed a new approach to study, capture, and purify medical isotopes, including actinium, which leverages a natural protein. IMAGE: THOMAS REASON/LLNL

Radioactive metals for medicine get a boost from recently discovered protein

A protein can be used to recover and purify radioactive metals such as actinium that could be beneficial for next-generation drugs used in cancer therapies and medical imaging, according to new research from Penn State and Lawrence Livermore National Laboratory (LLNL).

New podcast tracks the evolution of diverse human traits

“Tracking Traits,” a new podcast launched by Penn State’s Center for Human Evolution and Diversity (CHED), explores the current work of researchers who are forging new pathways to understanding the evolution of human diversity, via a wide variety of approaches.
