Princeton University researchers are using synthetic diamonds to help create a quantum communication network. Quantum information networks could be extremely secure and could also allow new quantum computers to work together to solve currently unsolvable problems. The main problem has been to preserve fragile quantum information over long distances. Researcher were able to store and …
Ada Diamonds offers only laboratory-grown diamonds in our fine jewelry. Ada’s sustainably cultured diamonds have the exact same crystal structure, chemical composition, optical properties, and physical properties as mined diamond. Ada’s gemstones are graded on the exact same criteria as mined diamonds (the Four Cs), by the same independent gemological laboratories that grade Earth-extracted diamonds. …
Gem Diamonds has found a 910-carat stone, about the size of two golf balls, at its Letseng mine in southern Africa. D color Type IIa diamond from the Letšeng mine in Lesotho, the highest dollar per carat kimberlite diamond mine in the world. The diamond, the largest recovered from Letšeng, is believed to be the …
Scientists at the Advanced Science Research Center (ASRC) at the Graduate Center, CUNY, worked to theorize and test how two layers of graphene — each one-atom thick — could be made to transform into a diamond-like material upon impact at room temperature. The team also found the moment of conversion resulted in a sudden reduction …
Stanford Linear Accelerator Lab (SLAC) scientists were able to observe “diamond rain” for the first time as it formed in high-pressure conditions. Extremely high pressure squeezes hydrogen and carbon found in the interior of these planets to form solid diamonds that sink slowly down further into the interior. The glittering precipitation has long been hypothesized …
A team of researchers from MIT, Harvard University, and Sandia National Laboratories reports a new technique for creating targeted defects in diamond materials, which is simpler and more precise than its predecessors and could benefit diamond-based quantum computing devices. Quantum computers are experimental devices that offer large speedups on some computational problems. One promising approach …
Russia’s reserve fund could be depleted in mid-2017, perhaps a few months later,” said Ondrej Schneider, chief economist at the Institute of International Finance. Russia may start building up its Reserve Fund in the second half of 2017, Finance Minister Anton Siluanov said January. This would be if oil prices average $50 per barrel and …
F-35s, F-22s and other fighter jets will soon use improved “artificial intelligence” to control nearby drone “wingmen” able to carry weapons, test enemy air defenses or perform intelligence, reconnaissance and surveillance missions in high risk areas, senior Air Force officials said. Air Force Chief Scientist Gregory Zacharias said that technology was progressing quickly at the …
In China’s three big population centres—the areas around Beijing in the north, Shanghai in the east and Guangzhou, the capital of Guangdong province, in the south—life and work have started to follow the sinews of the high-speed rail system. Trains were previously too infrequent, too slow and too crowded to allow for daily commutes. Now, …
As of August 2016, the US has already appropriated, spent, or taken on obligations to spend more than $3.6 trillion in current dollars on the wars in Iraq, Afghanistan, Pakistan and Syria and on Homeland Security (2001 through fiscal year 2016). To this total should be added the approximately $65 billion in dedicated war spending …
Cells in the amniotic fluid that surrounds a developing baby can revive ageing and weak bones, say UK scientists. The discovery could help babies with genetic diseases, elderly people and even astronauts, they say. The findings in mice, published in Scientific Reports, showed cells in the fluid strengthened bone and cut fractures by 80%. Human …
