Written by Molly Sharlach, Office of Engineering Communications

Using sophisticated algorithms to explore regions of the genome whose roles in cancer have been largely uncharted, an international team of researchers has opened the door to a new understanding of the disease’s genetic origins.

The discovery involves areas of DNA that do not directly code for…

By recreating cell division in a test tube, researchers discover vital role for protein elevated in a quarter of all cancers
Jan. 15, 2020

Researchers at Princeton University have successfully recreated a key cell-division step in a test tube, uncovering the vital role played by a protein that is elevated in over 25% of all cancers. The two studies, which appear today in the journals Nature Communications and eLife, are from the laboratory of Sabine Petry, assistant professor of…

Author
Written by Morgan Kelly, Princeton Environmental Institute

One of the first studies to examine the effect of climate change on diseases such as influenza that are transmitted directly from person to person has found that higher temperatures and increased rainfall could make outbreaks less severe but more common, particularly in North America.

Princeton University-led researchers studied how…
