Water quality improves after lawn fertilizer ban

A new study shows that elderly patients who underwent endoscopy within one day of presentation for peptic ulcer bleeding had a two-day shorter hospital stay and were less likely to require upper gastrointestinal surgery than patients who did not receive endoscopy within the first day of presentation. Researchers from University Hospitals Case Medical Center in Cleveland, Ohio, note that unless specific contraindications exist, the data supports the routine use of early endoscopy for upper gastrointestinal bleeding.

New paradigms in research of biomolecular composition of water

Water nurtures life in all its forms, but not all water in our life systems is equal. Water in a lake, in the sea or in a cup of tea is different from the water in our bodies. This much we do know. Yet science does not yet have a complete understanding as to why intracellular water is different to other water forms.

NASA satellites eye coastal water quality

Using data from instruments aboard NASA satellites, Zhiqiang Chen and colleagues at the University of South Florida in St. Petersburg, found that they can monitor water quality almost daily, rather than monthly. Such information has direct application for resource managers devising restoration plans for coastal water ecosystems and federal and state regulators in charge of defining water quality standards.
