Scientists identify enzymes that create a highly toxic form of mercury in Antarctic sea ice

02-Sep-2016

Researchers from Lawrence Livermore National Laboratory (LLNL) assisted a team from the University of Melbourne in discovering how methylmercury enters the Antarctic sea and bioaccumulates in the marine food web. LLNL scientists Michael Thelen and Adam Zemla performed protein sequence analysis ...

Mercury in fish affected by both prey type and quality

10-May-2016

Whether fish hunt nearshore or in the open water and what prey they eat affect the amount of mercury that accumulates in them, a Dartmouth College study shows. Mercury accumulation in fish poses well-known health risks to humans and wildlife, but fish mercury levels are highly variable and key ...

Tiny microbots that can clean up water

Self-propelled tiny ‘microbots’ that can remove pollution from contaminated water developed.

03-May-2016

Working with colleagues in Barcelona and Singapore, Samuel Sánchez’s group used graphene oxide to make their microscale motors, which are able to adsorb lead from industrial wastewater from a level of 1000 parts-per-billion to down to below 50 parts-per-billion in just an hour. The lead can ...

Researcher finds gold - and other metals

Gold sensor is latest in a series of metal-detecting biosensors

22-Feb-2016

Instead of a pan and a pick ax, prospectors of the future might seek gold with a hand-held biosensor that uses a component of DNA to detect traces of the element in water. The gold sensor is the latest in a series of metal-detecting biosensors under development by Rebecca Lai, an associate ...

Highly efficient heavy metal ions filter

27-Jan-2016

ETH researchers have developed a new water filtration system that is superior to existing systems in many respects: it is extremely efficient at removing various toxic heavy metal ions and radioactive substances from water and can even be used in gold recovery. In November, Brazil experienced an ...

New research sheds light on mercury pollution in estuaries, food chain

09-Dec-2015

Two studies by Dartmouth researchers and their colleagues shed new light on mercury pollution in the waters of the northeastern United States. Mercury, which is transformed into methylmercury in water, is a global pollutant that damages human health. Most people are exposed to mercury by eating ...

How mercury contamination affects reptiles in the Amazon basin

23-Sep-2015

Mercury contamination in water and on land is of worldwide concern due to its toxic effects on ecosystems and human health. Mercury toxicity is of particular concern to reptiles because they are currently experiencing population declines. Also, reptiles are ideal indicators of mercury ...

TU Vienna develops light transistor

09-Jul-2013

TU Vienna has managed to turn the oscillation direction of beams of light -- simply by applying an electrical current to a special material. This way, a transistor can be built that functions with light instead of electrical current. Light can oscillate in different directions, as we can see in ...

Liquid on liquid goes solid

Kiel based research group discovers nano-crystals at the interface between two liquids

12-Apr-2013

Not all liquids are mixable. Researchers from the Institute of Experimental and Applied Physics of Kiel University (CAU) have investigated chemical processes with atomic resolution at the interface between two such liquids and have made an exciting discovery. During an experiment carried out at ...
