Using less fish to test chemicals safety

The JRC has released a new strategy on how to replace reduce and refine the use of fish in testing of chemicals' effect on flora and fauna in water aquatic toxicity and chemicals' uptake and ... - Read More

Sequestration on shaky ground: Natural impediment to long-term sequestration of carbon dioxide

Carbon sequestration promises to address greenhouse gas emissions by capturing carbon dioxide from the atmosphere and injecting it deep below the Earth's surface where it would permanently solidify into rock The U S Environmental Protection ... - Read More

Graphene enables all-electrical control of energy flow from light emitters

At the heart of lasers displays and other light emitting devices lies the emission of photons Electrically controlled modulation of this emission is of great importance in applications such as optical communication sensors and displays ... - Read More

Voyage from Earth's crust to its mantle and back again

Uranium isotopes leave a distinct 'fingerprint' in the sources of volcanic rocks making it possible to gauge their age and origin Geologists have gained a new understanding of how Earth's crust is recycled back into ... - Read More

They see flow signals: Researchers identify nature of 'sixth sense' in fish

A team of scientists has identified how a sixth sense in fish allows them to detect flows of water which helps resolve a long standing mystery about how these aquatic creatures respond to their environment ... - Read More

Iron toxicity for cyanobacteria delayed oxygen accumulation in early Earth's atmosphere

Three billion years ago Earth's atmosphere contained less than 0.0001 percent oxygen Today's atmosphere has around 20 percent oxygen and that is due to the work of tiny microorganisms in Earth's primeval oceans Cyanobacteria which ... - Read More

Responsive material could be the 'golden ticket' of sensing

Researchers from the University of Cambridge have developed a new self assembled material which by changing its shape can amplify small variations in temperature and concentration of biomolecules making them easier to detect The material ... - Read More

Oil sand mining is not polluting Athabasca Delta, new sampling method reveals

A new study into the pre industrial baseline levels of heavy metals in sediment carried by the Athabasca River shows that emissions from the Alberta oil sands and other human activities have not yet increased ... - Read More

Ultrasounds dance the 'moonwalk' in new metamaterial

Metamaterials have extraordinary properties when it comes to diverting and controlling waves especially sound and light for instance they can make an object invisible or increase the resolving power of a lens Now researchers at ... - Read More

NASA Goddard instrument makes first detection of organic matter on Mars

The team responsible for the Sample Analysis at Mars SAM instrument suite on NASA's Curiosity rover has made the first definitive detection of organic molecules at Mars Organic molecules are the building blocks of all ... - Read More

New way to diagnose brain damage from concussions, strokes, and dementia

New optical diagnostic technology developed at Tufts University School of Engineering promises new ways to identify and monitor brain damage resulting from traumatic injury stroke or vascular dementia in real time and without invasive procedures ... - Read More

No laughing matter: Nitrous oxide rose at end of last ice age

Nitrous oxide N2O is an important greenhouse gas that doesn't receive as much notoriety as carbon dioxide or methane but a new study confirms that atmospheric levels of N2O rose significantly as the Earth came ... - Read More

Solid-state proteins maximize intensity of fluorescent-protein-based lasers

The same research team that developed the first laser based on a living cell has shown that use of fluorescent proteins in a solid form rather than in solution greatly increases the intensity of light ... - Read More

Fracking and pollution: Technology-dependent emissions of gas extraction in the US

Not all boreholes are the same Scientists of the Karlsruhe Institute of Technology KIT used mobile measurement equipment to analyze gaseous compounds emitted by the extraction of oil and natural gas in the USA For ... - Read More

Permafrost soil: Possible source of abrupt rise in greenhouse gases at end of last ice age

Scientists from the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research AWI have identified a possible source of carbon dioxide CO2 and other greenhouse gases that were abruptly released to the atmosphere in ... - Read More

Scientists' new analysis of plant proteins advances our understanding of photosynthesis

A world without plants would be a world without oxygen uninhabitable for us and for many creatures We know plants release oxygen by absorbing carbon dioxide and breaking down water using sunlight through the process ... - Read More

Clean smell doesn't always mean clean air

Some of the same chemical reactions that occur in the atmosphere as a result of smog and ozone are actually taking place in your house while you are cleaning A researcher in Drexel's College of ... - Read More

New devices based on metamaterials

Víctor Torres Landivar Telecommunications engineer has designed and manufactured new devices based on metamaterials artificial materials with properties not found in nature On drawing up his PhD defended at the Public University of Navarre UPNA ... - Read More

Wild molecular interactions in a new hydrogen mixture

Hydrogen the most abundant element in the cosmos responds to extremes of pressure and temperature differently Under ambient conditions hydrogen is a gaseous two atom molecule As confinement pressure increases the molecules adopt different states ... - Read More

Dispelling a misconception about Mg-ion batteries

Lithium Li ion batteries serve us well powering our laptops tablets cell phones and a host of other gadgets and devices However for future automotive applications we will need rechargeable batteries with significant increases in ... - Read More
