Hyenas inherit their moms’ social connections Penn In the News Psychology Today Hyenas inherit their moms’ social connections Erol Akçay of the School of Arts & Sciences and former postdoc Amiyaal Ilany discussed their research on hyena’s social networks. “We show that a simple process—social inheritance—is important to understanding network structure and dynamics,” said Akçay. Biologist Daniel Janzen illustrates how a cicada is like an oak tree Biologist Daniel Janzen illustrates how a cicada is like an oak tree Janzen, the DiMaura Professor in Biology, on why cicadas (and wildebeests, salmon, and oak trees) act the way they do. Obscuring the truth can promote cooperation Obscuring the truth can promote cooperation People are more likely to cooperate if they think others are cooperating, too. New research by biologists in the School of Arts & Sciences shows that overstating the true level of cooperation in a society can increase cooperative behavior overall. Protein’s ‘silent code’ affects how cells move Protein’s ‘silent code’ affects how cells move A School of Veterinary Medicine-led study shows how, despite having nearly identical amino acid sequences, two forms of the protein actin differ in function due their distinct nucleotide sequences. ’Social’ mitochondria, whispering between cells, influence health Penn In the News Quanta Magazine ’Social’ mitochondria, whispering between cells, influence health James Eberwine of the Perelman School of Medicine spoke about how mitochondria interact, communicate, and mutate. “If we understand how the mitochondria are acting together, and we learn how to manipulate it,” he said, “we’re going to gain so much more insight into biology.” With remarkable similarities to MS, a disease in dogs opens new avenues for study A naturally occurring canine disease called granulomatous meningoencephalomyelitis replicates many features of multiple sclerosis, including the involvement of B cells (in red) and T cells (green) in the tissues that line the central nervous system. (Image: Penn Vet) With remarkable similarities to MS, a disease in dogs opens new avenues for study Researchers at the School of Veterinary Medicine led by Jorge Iván Alvarez and Molly Church found that the canine disease granulomatous meningoencephalomyelitis shares many of the same pathological and immunological features as MS.

Pinpointing how cancer cells turn aggressive Pinpointing how cancer cells turn aggressive Penn scientists have developed a new method for tracing the lineage and gene expression patterns of metastatic cancer at the single-cell level.
