New therapy may help treat skin cancer, say scientists

Washington : Scientists say they have identified a molecule that can be added to a cancer vaccine to boost the immune system’s ability to fight skin cancer.

A study, published in the journal PNAS, found that adding the molecule called Diprovocim to an existing vaccine can draw cancer-fighting cells to tumour sites. Experiments in mice with melanoma...

Poor grades? Blame your genes, scientists say

Artificial Intelligence system can identify cancer tumours better than humans

Washington, Aug 26: Scientists have developed an artificial intelligence system that can accurately detect tiny specks of lung cancer in CT scans, which radiologists often have a difficult time identifying. The AI system is about 95 per cent accurate, compared to 65 per cent when done by human eyes, researchers said.

“We used the brain as a...
