Bacteria fed by algae biochemicals can harm coral health

Though corals worldwide are threatened due to climate change and local stressors, the front lines of the battle are microscopic in scale. Under stress, many reefs that were formerly dominated by coral are shifting to systems ...

How did the old masters make their ultramarine?

Researchers at the Rijksmuseum, the University of Amsterdam, VU Amsterdam and the European Synchrotron Radiation Facility (ESRF) have developed a method that reveals how the costly pigment ultramarine was prepared from the ...

A tale of shepherds and helices

The relief "Adoration of the Shepherds" by the Italian sculptor Giuseppe Torretti is disfigured by lumpy salt crystals. Now, a research group at the Max Planck Institute for Solid State Research in Stuttgart has established ...

Synthetic synapses get more like a real brain

The human brain, fed on just the calorie input of a modest diet, easily outperforms state-of-the-art supercomputers powered by full-scale station energy inputs. The difference stems from the multiple states of brain processes ...

Ocean changes almost starved life of oxygen

Chemical changes in the oceans more than 800 million years ago almost destroyed the oxygen-rich atmosphere that paved the way for complex life on Earth, new research suggests.

Plants can detect insect attacks by 'sniffing' each other's aromas

Fragrant aromas from plants can actually be a response to attacks by insects, and can alert neighbours to an attack or summon the insects' predators. Now, scientists are deciphering these secret codes to develop better, greener ...

Researchers develop new method for analyzing metal

Warfighters on the battlefield often rely on machines, vehicles and other technologies with rotating parts to complete their mission. Army researchers have devised a new method of testing for a major factor in equipment failure ...
