How the sensory organs of bacteria function

Bacteria can occur almost anywhere on earth and exist under the most varying conditions. If these tiny, microscopic organisms are to survive in these environments, they need to be able to rapidly detect changes in their surroundings and react to them.

Key survival circuit discovered in Salmonella bacteria

Hundreds of trillions of bacteria make their home in the vertebrate gut. Though many of these microbes perform helpful duties for their host, others - the pathogens - are unwelcome visitors, causing disease.

Biologist provides new theory on mechanisms that control molecular motors

Biologists have known for decades that cells use tiny molecular motors to move chromosomes, mitochondria, and many other organelles within the cell, but no one has been able to understand what "steers" these engines to their destinations.

An Achilles heel in cancer cells

A protein that shields tumor cells from cell death and exerts resistance to chemotherapy has an Achilles heel, a vulnerability that can be exploited to target and kill the very tumor cells it usually protects, researchers from the University of Illinois at Chicago show in a new study published in the Dec. 9 issue of Cancer Cell.
