New model helps define optimal temperature and pressure to forge nanoscale diamonds  

To forge nanodiamonds, which have potential applications in medicine, optoelectronics and quantum computing, researchers expose organic explosive molecules to powerful detonations in a controlled environment. These explosive forces, however, make it difficult to study the nanodiamond formation process. To overcome this hurdle, researchers recently developed a procedure and a computer model that can simulate the highly variable conditions of explosions on phenomenally short time scales.

how climate change could cause global beer shortages  

Severe climate events could cause shortages in the global beer supply, according to new research. The study warns that increasingly widespread and severe drought and heat may cause substantial decreases in barley yields worldwide, affecting the supply used to make beer, and ultimately resulting in 'dramatic' falls in beer consumption and rises in beer prices.

Tracking the movement of the tropics 800 years into the past  

For the first time, scientists have traced the north-south shifts of the northern-most edge of the tropics back 800 years. The movement of the tropical boundary affects the locations of Northern Hemisphere deserts including the Sonoran, Mohave and Saharan. The Earth's climate system affects the movement of the tropics, which have been expanding since the 1970s. The research team found that in the past, periods of tropical expansion coincided with severe droughts.

The state of the early universe: The beginning was fluid  

Scientists recently collided Xenon nuclei, in order to gain new insights into the properties of the Quark-Gluon Plasma (the QGP). The QGP is a special state consisting of the fundamental particles, the quarks, and the particles that bind the quarks together, the gluons. The result was obtained using the ALICE experiment at the superconducting Large Hadron Collider.

Unravelling the genetics of fungal fratricide  

Selfish genes are genes that are passed on to the next generation but confer no advantage on the individual as a whole, and may sometimes be harmful. Researchers have, for the first time, sequenced (or charted) two selfish genes in the fungus Neurospora intermedia that cause fungal spores to kill their siblings. Unexpectedly, the genes were not related to each other, perhaps indicating that selfish genes are more common than previously thought.

Early changes to synapse gene regulation may cause Alzheimer's disease  

New research has revealed a role for splicing proteins in the pathology of Alzheimer's disease. Increased phosphorylation of the SRRM2 protein, seen in AD mouse models and human patients, was found to block its transport to the nucleus.
