Credit: NIAID A clinical trial testing a freeze-dried, temperature-stable experimental tuberculosis (TB) vaccine in healthy adults found that it was safe and stimulated both antibodies and responses from the cellular arm of the immune system. The Phase...

by Christopher Vaughan, Stanford University Medical Center Credit: Unsplash/CC0 Public Domain Some cities fight gangs with ex-members who educate kids and starve gangs of new recruits. Stanford Medicine researchers have done something similar with cancer—altering cancer cells so that they teach the body’s immune system to fight the very cancer the cells came from. “This approach could...

by Hiroshima University Credit: Andrea Piacquadio/Pexels Just as computer devices acting differently can hint at the possibility of malware lurking in the background, changes in brain patterns that shape trust behavior can warn of depression even if symptoms are still in stealth mode, a study found. Brain scans revealed that shrunken gray matter volumes in...

Studying the brain is difficult, and often involves invasive techniques, such as using a probe, to gain information about electrical signaling. This means our understanding of exactly how brain signaling works is limited, which has implications for basic science and medical research....
Researchers say sugar can affect cysts that may be a factor in a common type of kidney disease. Oliver Bunic/Bloomberg via Getty Images New research conducted in a laboratory setting may potentially have significant effects on the management of polycystic kidney disease (PKD), a condition impacting more than 500,000 individuals in the United States. Organoids...
by University of Chicago Medical Center Credit: Unsplash/CC0 Public Domain Immunotherapies have been successful in treating many cancer conditions; however, not much success has yet been achieved in metastatic castrate-resistant prostate cancer (mCRPC). A study published March 2 in Clinical Cancer Research has revealed new insights into why immunotherapies don’t tend to work as well in prostate cancer....
