Discovery suggests a new way to slow or stop metastatic spread of pancreatic cancer

Pancreatic cancer, though rare, is one of the deadliest of cancers, killing nearly 50,000 people yearly and doing so quickly, primarily because it metastasizes rapidly through the body. Barely one in 10 people survive beyond five years.

Bacterium discovery helps to solve the puzzle of what factors limit cell size

On sunken leaves in the waters of a Caribbean mangrove swamp, researchers discovered a bacterium that challenges the prevailing view of bacterial cell size; counter to the notion that microbes are only visible with a microscope, this one – named Thiomargarita magnifica – is larger than all other known giant bacteria by ~50-fold, and can be seen by the naked eye, the study's authors say.
