Researchers discover mechanism that prevents two species from reproducing
Cornell researchers have discovered a genetic mechanism in fruit flies that prevents two closely related species from reproducing, a finding that offers clues to how species evolve.   view more (2009-10-27)

Concurrent imaging of metabolic and electric signals in the heart
Cardiac rhythm disorders can result from disturbances in cardiac metabolism. These metabolic changes are tightly linked with specific cardiac electrophysiology (CEP) abnormalities, such as depressed excitability, impaired intra- and extracellular conductivities, wave propagation block, and alteration of conduction velocity, action potential... view more...

Checkered history of mother and daughter cells explains cell cycle differences
When mother and daughter cells are created each time a cell divides, they are not exactly alike. They have the same set of genes, but differ in the way they regulate them.   view more (2009-10-20)

Breast milk should be drunk at the same time of day that it is expressed
The levels of the components in breast milk change every 24 hours in response to the needs of the baby. A new study published in the journal Nutritional Neuroscience shows, for example, how this milk could help newborn babies to sleep.    view more (2009-10-01)

Lies my parents told me
