This newly acquired knowledg...

A research team led by Professor Sei Kwang Hahn of the Department of Materials Science and Engineering and Professor Kilwon Cho of the Department of Chemical Engineering at POSTEC...

The data was published ...

Date Time Viruses Mutate, But Treatments Are Static. Is There a Way to Change That? There is a big, global problem: viruses such as HIV and COVID-19 mutate, but treatments for them don’t. For more than 20 years, Leor Weinberger, PhD, has been thinking about how to make vaccines work more efficiently by being adaptive, rather than static. A human T cell (blue) is under attack by HIV (yellow), the virus that causes AIDS.
