Fluorescence method detects mercury contamination in fish
February 21, 2017 11:25 AM - Plataforma SINC

Researchers from the University of Burgos (Spain) have developed a fluorescent polymer that lights up in contact with mercury that may be present in fish. High levels of the metal were detected in samples of swordfish and tuna. According to the conclusions of another Spanish study, mercury exposure is linked to reduced foetal and placental growth in pregnant women.

The presence of the toxic metal mercury in the environment comes from natural sources, however, in the last decades industrial waste has caused an increase in concentrations of the metal in some areas of the sea. In the food chain, mercury can be diluted either in organic form as methylmercury (MeHg+) or as an inorganic salt, the cation Hg2+.

One morning in February 2015, I felt a rumble. Was it an earthquake? No. It was an explosion at the ExxonMobil oil refinery a few miles away. The refinery is located in the middle of a residential area of Torrance, Calif.

Fish affected by Deepwater Horizon spill give clues to air pollution heart disease
February 17, 2017 02:25 PM - Manchester University

A study by Manchester and Stanford scientists into the effects on fish of a 2010 oil disaster could shed new light on how air pollution affects humans’ hearts.

The 2010 Deepwater Horizon disaster resulted in a major oil spill in the Gulf of Mexico, an area of water which is heavily populated with fish species. In a paper published in Nature Scientific Reports, the team analysed the effects of individual components of crude oil on the hearts of fish.

Real-Time MRI Analysis Powered by Supercomputers
February 16, 2017 01:15 PM - University of Texas at Austin, Texas Advanced Computing Center

One of the main tools doctors use to detect diseases and injuries in cases ranging from multiple sclerosis to broken bones is magnetic resonance imaging (MRI). However, the results of an MRI scan take hours or days to interpret and analyze. This means that if a more detailed investigation is needed, or there is a problem with the scan, the patient needs to return for a follow-up.
