Paper can't cover fire!
The true experts engaged in academia almost keep an eye on the top journals in their field every day. The moment a new issue is released, they immediately start reading, seizing the information they desire. This is how they keep up with the leading-edge research worldwide, lest they fall behind.
Such top journals had always been amongst the main reading materials on Professor Su's bookshelf.
Nowadays, many international journals are printed and mailed in the country of sale, and thanks to the developed logistics industry, a new issue of a journal can be delivered to readers within a few days.
Because there was an article by Yang Ping in "Science", Professor Su paid extra attention to this issue. He took a "Science" magazine that still smelled of fresh ink from the shelf. The cover featured the title of Yang Ping's paper on skin expansion technology.
