Antibody Alarm Call Rouses Immune Response to Cancer
from Nature News
Researchers working in the burgeoning field of cancer immunotherapy last week announced that a way of arming the body's natural defences to fight tumour cells has proved effective against three different types of cancer.
An antibody-based treatment developed by Suzanne Topalian, an oncologist at the Johns Hopkins University in Baltimore, Maryland, and her colleagues either eliminated or shrank tumours in 49 of 236 patients with certain types of advanced skin, kidney and lung cancer. Previous cancer immunotherapies have worked in smaller percentages of patients. The results of the phase I clinical trial were published on 2 June [in the New England Journal of Medicine].
"I think it really changes the field, because the response rates are much higher," says Antoni Ribas, a cancer researcher at the Jonsson Comprehensive Cancer Center of the University of California, Los Angeles, who is testing a similar treatment in clinical trials.

PODCASTS: From Balloons to Space Stations: Studying Cosmic Rays
Cosmic rays have mysterious qualities about them that scientists continue to research in order to better understand their origins and composition. Dr. Eun-Suk Seo, a professor of physics at the University of Maryland, and her colleagues, fly enormous balloons as large as a football stadium and a volume of 40-million-cubic feet for extended periods over Antarctica to study particles coming from cosmic rays before they break up in the atmosphere.
