NHK has used artificial intelligence to analyze about 200,000 papers published around the world in English on the coronavirus. It found that at least 116 symptoms have been reported.

The symptoms include loss of taste, dryness of the eyes, nettle rash as well as fever and pneumonia.

A group of researchers in Japan says it is using immune cells derived from induced pluripotent stem cells, or iPS cells, in a clinical trial for cancer treatment.

The researchers say the clinical test started this month at Chiba University Hospital, near Tokyo, and is the first in the country to apply iPS cells to treat cancer.
