...iginating in the root, helps regulate the critical early
days of leaf development. How plants coordinate the development of their shoot and root structures with signals from the environment is a major unsolved problem in plant biology. It is known that plant roots, whose primary role is to supply wate...

1980s. (Dr. Hunt won the Nobel Prize in 2001 for this discovery.) By 1989, MBL scientists had developed a means of studying cyclins and the cell cycle in the test tube using the eggs of local surf clams as models. It turned out to be exactly th...
Researchers find chemosignal that encourages women's sexual desire
... Other research suggests that women living in early
societies produced children when food resources were plentiful. The chemosignal would have been a way of encouraging other women to reproduce when circumstances were optimal. In 1998, McClintock and other researchers at the institute pro...
Old bones unearth new date for giant deer's last stand

man develop an appetite for supersized deer? Professor Adrian Lister says: "Although we can now bring the extinction date forward by 3,000 years or so, we still can't tell what actually killed off these beasts. Man could have been the ultimate destro...
