Historic iceberg surges offer insights on modern climate change      (via sciencedaily.com)     Original source 

A great armada entered the North Atlantic, launched from the cold shores of North America. But rather than ships off to war, this force was a fleet of icebergs. And the havoc it wrought was to the ocean current itself. The future of the Atlantic circulation will be determined by a tug-o-war between Greenland's decreasing ice flux and its increasing freshwater runoff.

Combining simulations and experiments to get the best out of Fe3Al      (via sciencedaily.com)     Original source 

Researchers combined computer simulations and transmission electron microscopy experiments to better understand the ordering mobility and formation of microstructure domains in Fe3Al alloy. They were able to correlate structural changes with heat treatment to understand how particular mechanical behavior can be achieved. This is expected to allow the superelastic properties of Fe3Al to harnessed for the 3D printing of construction materials for absorbing seismic activity.

Local bright spot among melting glaciers: 2000 km of Antarctic ice-covered coastline has been stable for 85 years      (via sciencedaily.com)     Original source 

A whaler's forgotten aerial photos from 1937 have given researchers the most detailed picture of the ice evolution in East Antarctica to date. The results show that the ice has remained stable and even grown slightly over almost a century, though scientists observe early signs of weakening. The research offers new insights that enhance predictions of ice changes and sea level rise.

Indian Ocean surface temperature could help anticipate dengue outbreaks      (via sciencedaily.com)     Original source 

Although dengue outbreaks cannot be prevented, it is possible to anticipate them. Scientists have recently identified a global climate indicator that may help improve predictions about the magnitude of dengue outbreaks several months in advance. This indicator, which can be used for any world region, is based on temperature fluctuations at the surface of the Indian Ocean. Obtaining reliable long-term predictions could facilitate efforts to tackle this infection, which has been on the rise for several decades and threatens half of the world's population.

Fatal attraction: When endangered species try to mate with domestic relatives, both wildlife and people lose      (via sciencedaily.com)     Original source 

Sticks and stones aren't enough to thwart biological attraction, but sometimes those are the only tools available to pastoralists trying to prevent wildlife from eloping with their livestock. A new study brings awareness to both the human impacts of these encounters -- ranging from economic loss to death -- and conservation concerns for the wild animals that are often endangered.

More than spins: Exploring uncharted territory in quantum devices      (via sciencedaily.com)     Original source 

Many of today's quantum devices rely on collections of qubits, also called spins. These quantum bits have only two energy levels, the '0' and the '1'. However, spins in real devices also interact with light and vibrations known as bosons, greatly complicating calculations. Researchers now demonstrate a way to describe spin-boson systems and use this to efficiently configure quantum devices in a desired state.

Shedding light on the chemical enigma of sulfur trioxide in the atmosphere      (via sciencedaily.com)     Original source 

Researchers discovered that sulfur trioxide can form products other than sulfuric acid in the atmosphere by interacting with organic and inorganic acids. These previously uncharacterized acid sulfuric anhydride products are almost certainly key contributors to atmospheric new particle formation and a way to efficiently incorporate carboxylic acids into atmospheric nanoparticles. Better prediction of aerosol formation can help curb air pollution and reduce uncertainties concerning climate change.
