Did the great flood of Noah's generation really occur thousands of years ago? Was the Roman city of Caesarea destroyed by an ancient tsunami? Will pollution levels in our deep seas remain forever a mystery? These are just a few of the questions that are being addressed by a new environmental marine research team. Scientists and Swedish environmental philanthropist Andreas Weil are collaborating on an adventure in research aboard "The Mediterranean Explorer." The floating laboratory and educational facility is taking on some of the deepest mysteries of the Mediterranean waters and is bringing together scientists from diverse cultures and backgrounds. Issues of global warming, climate change, and even biblical history are being probed in this exciting initiative.

Researchers believe they have discovered why a bacterial lung infection is so lethal in the early stages, and it's not what medical authorities had thought. The study reveals for the first time that a toxin released by bacteria causes severe bleeding in the lungs by patients with pneumococcal pneumonia. It is the bleeding, the authors argue, not inflammation as once thought, which makes the infections deadly. The same study also reveals why antibiotics often fail to help prevent early death. Despite vaccine, one million children still die of pneumococcal infections.
