Manhasset, USA.- Northwell Health's Feinstein Institute for Medical Research Associate Professor Ona E. Bloom, PhD, along with colleagues at the Marine Biological Laboratory (MBL), published today in Scientific Reports that many of the genes that repair an injured spinal cord in a fish called the lamprey are also active in the repair of the peripheral nervous system in mammals. This discovery is significant because it shows the possibility that the same or similar genes may be used to improve spinal cord repair in other animals and perhaps eventually lead to therapeutic developments for humans.

Norway.- An advanced light meter developed by Nofima is set to revolutionise the processing of fish. White fish can be sorted according to the amount of blood in the fillet before it is cut open, allowing better utilisation of each individual fish and better profitability for fishing companies.

Scientists studying calcium in a marine environment have discovered a direct link between the acidification of the seas in a changing climate and the rate at which mussels develop their calcified outer shell. The shell of a mussel protects it from predators and is formed at a very early stage of development. At this point, they are particularly sensitive to low pH levels in the ocean caused by increasing uptake of carbon dioxide from the atmosphere dissolved in seawater.

Germany.- Environmental DNA analysis makes it possible to detect water organisms without having to capture them first. For the first time, a team at the Technical University of Munich (TUM) systematically investigated the effect of various environmental factors on environmental DNA analyses. By doing so, the researchers have made an important step towards the standardized application of this method for the monitoring of water bodies.

USA.- Land-based management has reduced nutrient discharges; however, many coastal waterbodies remain impaired. Oyster “bioextraction” of nutrients and how oyster aquaculture might complement existing management measures in urban estuaries was examined in Long Island Sound, Connecticut. Eutrophication status, nutrient removal, and ecosystem service values were estimated using eutrophication, circulation, local- and ecosystem-scale models, and an avoided-costs valuation.
