Cancer cells need oxygen to survive, as do most other life forms, but scientists had never tracked their search for oxygen in their early growth stages until now — a step toward deeper understanding of one way cancer spreads that could help treat the disease.

Five Johns Hopkins graduate students, recently named to the 2016 class of Siebel Scholars, are each pursuing bioengineering projects that could lead to important new diagnostic and treatment advances in healthcare. The merit-based Siebel program has recognized their research skills, academic achievements and leadership qualities by providing $35,000 to each of the five PhD candidates for use in his or her final year of graduate studies.
A Johns Hopkins engineer who is designing cancer-fighting nano-size structures that could assemble themselves and deliver treatment to diseased tissue has received a Faculty Early Career Development (CAREER) Award from the National Science Foundation. Honggang Cui, an assistant professor in the Department of Chemical and Biomolecular Engineering at Johns Hopkins, has been given this honor, which is accompanied by nearly $500,000 that will be disbursed over five years.
In life, we sort soiled laundry from clean; ripe fruit from rotten. Two Johns Hopkins engineers say they have found an easy way to use gravity or simple forces to similarly sort microscopic particles and bits of biological matter—including circulating tumor cells.
Johns Hopkins researchers have devised a protein “switch” that instructs cancer cells to produce their own anti-cancer medication. In lab tests, the researchers showed that these switches, working from inside the cells, can activate a powerful cell-killing drug when the device detects a marker linked to cancer. The goal, the scientists said, is to deploy a new type of weapon that causes cancer cells to self-destruct while sparing healthy tissue.
A Johns Hopkins undergraduate team that assembled fragments of DNA in a way that allows cells to respond to electrical “messages” has received recognition in an international contest in the emerging field of synthetic biology. The students competed this month in the latest International Genetically Engineered Machine competition, also known as iGEM 2010.
