Abstract: Persistent organic pollutants (POPs) can cause long term damage to the environment. Two classes of organic molecules have come to the attention of regulators and water treatment authorities in recent years; iodinated X-Ray contrast media (XCM) and artificial sweeteners (AS). These molecules, by design, have a high degree of stability. Aware of the increased abundance of these molecules in waste water, the IWB Water Laboratory set out to develop a robust, simple method to analyse levels of these molecules in water from the river Rhine, ground water and drinking water.

Like great athletes and musicians, cells employed in cell-based assays or as expression systems for biopharmaceutical production are not born, but made. Cell lines that perform specifically and predictably arise from a population of cells that have undergone one or more genetic transformations (transfection) and are subsequently selected for desirable properties such as viability, protein or virus production; high culture density; or binding to drugs or antigens.

A Washington University in St. Louis drug discovery program has received three grants totaling more than $5 million from the National Institutes of Health (NIH) to develop new therapeutics for respiratory diseases. The target illnesses range from the common cold to life-threatening lung disease.

Researchers have collaborated to craft a request that could fundamentally alter how the antibodies used in research are identified.

Many people imagine robots today as clunky, metal versions of humans, but scientists are forging new territory in the field of 'soft robotics.' One of the latest advances is a flexible, microscopic hand-like gripper. The development could help doctors perform remotely guided surgical procedures or perform biopsies.

Research actually provides further support for Darwin, UCLA professor says.
