How cells size up their growth opportunities

The intricate mechanisms that switch cell growth on and off are regulated by mammalian target of rapamycin (mTOR) protein complexes, which sense nutrients within the cell. When amino-acids are abundant, the protein complexes promote cellular growth, and when nutrients are scarce they signal that hard times are ahead to the cell. But just how nutrients regulate mTOR signaling to control size has remained a mystery. Now, scientists in the lab of Whitehead Member David Sabatini have found the first step in the process.

Bypass not to blame for heart patients' mental decline

Heart patients often experience lasting problems with memory, language, and other cognitive skills after bypass surgery.

The findings may lead to better approaches to prevent cognitive decline regardless of which treatment heart disease patients receive.
