Harvard researchers have solved the nearly 200-year-old mystery of how Rafflesia, the largest flowering plants in the world, develop.
Record warmth in 2010 and 2012 resulted in similarly extraordinary spring flowering in the eastern United States — the earliest in the more than 150 years for which data is available— researchers at Harvard University, Boston University, and the University of Wisconsin have found.
Researchers have found that a parasitic flower takes large portions of its genetic code from its host, and that some genes borrowed by the flowers may even be functional. The surprising finding suggests that the process may convey some evolutionary advantage to the flowers.
The WATCH Portal, a new online child-care service, aims to connect Harvard parents with a vast pool of potential babysitters, from undergraduates and graduate students to the teenage children of employees.
Harvard botanist Charles Davis is examining evolutionary relationships between species affected by climate change for clues to past and future changes.
