NewsScientists tie lupus to a virus nearly all of us carry
The Epstein-Barr virus is directly responsible for commandeering what starts out as a minuscule number of immune cells to go rogue and persuade far more of their fellow immune cells to launch a widespread assault on the body’s tissues, a study has shown.

NewsTiny diatoms, big climate impact: How microscopic skeletons rapidly shape ocean chemistry
Researchers have found that diatoms’ intricate, silica-based skeletons transform into clay minerals in as little as 40 days. Until the 1990s, scientists believed that this enigmatic process took hundreds to thousands of years.
