Viruses are incapable of reproducing without the help of a host, whose cells copy their genetic material and fabricate the building blocks of new virus particles.
The COVID-19 pandemic is still with us. Biomedical innovation has rallied to address that pressing concern while continuing to tackle broader research challenges.
The scientific community bid farewell to researchers who furthered the fields of molecular biology, virology, sleep science, and immunology, among others.
The immune system tolerates the colonization of commensal bacteria on the skin with the aid of regulatory T cells during the first few weeks of life, a mouse study shows.
With dogged persistence and an unwillingness to entertain defeat, Bruce Beutler discovered a receptor that powers the innate immune response to infections—and earned his share of a Nobel Prize.
