Novel magnets made from the strongest known hydrogen bond

A team of scientists from the US, the UK and Germany has been the first to make a magnetic material constructed from nature's strongest known hydrogen bond. Hydrogen bonds are responsible for many of the properties of water ...

Researchers learn from analyses of rare tsunami earthquake

Analyses of a classic, slow-rupturing tsunami earthquake whose massive waves devastated the coast of Java, Indonesia, this past summer are providing insight to seismologists and engineers, who want to better understand these ...

Hotspots or not? Isotopes score one for traditional theory

New chemical evidence sheds light on the physical constraints of 'hotspots' -- locations where upwellings of Earth's mantle material form seamounts and island chains. Although the existence of hotspots has been debated over ...

No matter their size black holes 'feed' in the same way

Research by UK astronomers, published today in Nature reveals that the processes at work in black holes of all sizes are the same and that supermassive black holes are simply scaled up versions of small Galactic black holes.

Possible Signs of Liquid Water Flowing on Mars

NASA photographs have revealed bright new deposits seen in two gullies on Mars that suggest water carried sediment through them sometime during the past seven years.

Global warming will reduce ocean productivity, marine life

A 10-year, satellite-based analysis has shown for the first time that primary biological productivity in the oceans - the growth of phytoplankton that forms the basis for the rest of the marine food chain - is tightly linked ...

Elusive rust resistance genes located

The discovery of a DNA marker for two key rust resistance genes is enabling plant breeders around the world to breed more effective rust resistant wheat varieties.

CSIRO demonstrates world's fastest wireless link

The CSIRO ICT Centre today announced that it has achieved over six gigabits per second over a point to point wireless connection with the highest efficiency (2.4bits/s/Hz) ever achieved for such a system.

Do galaxies follow Darwinian evolution?

Using VIMOS on ESO's Very Large Telescope, a team of French and Italian astronomers have shown the strong influence the environment exerts on the way galaxies form and evolve. The scientists have for the first time charted ...
