A study suggests that nicotine promotes the spread of brain metastases by suppressing the innate immune function of cells present in the nervous system. In itself, nicotine is not a carcinogenic compound. However, this molecule is partly responsible for tobacco addiction. This is why it is used in

A Japanese scientist has developed a kind of electronic lollipop which is nothing more than a taste simulator. The goal? Make the user feel any taste without having to ingest food and relieve people on a special diet. The five human tastes reproduced Homei Miyashita is a researcher from Meiji Unive
