Tadiation detection properties have been identified in a light-emitting nanostructure made in a new way from two of the least expensive rare earth elements. The new material is made from two of the least expensive rare earth elements, so it is cost-effective, estimated at a little over $7 per cm3.
The extreme atmospheric conditions associated with California's crippling drought are far more likely to occur under today's global warming conditions than in the climate that existed before humans emitted large amounts of greenhouse gases, scientists say.
By exchanging specific atoms inside the mineral structure, quantum bits, required to process complex operations faster, could be stabilized.
DNA signature found in Ice Storm babies: Prenatal maternal stress exposure to natural disasters predicts epigenetic profile of offspring
The number of days an expectant mother was deprived of electricity during Quebec's Ice Storm in 1998 predicts the epigenetic profile of her child, a new study finds.
Australia's hottest year on record in 2013 along with the accompanying droughts, heat waves and record-breaking seasons of that year was virtually impossible without the influence of human-caused global warming, scientists say.
Certain primordial stars -- between 55,000 and 56,000 times the mass of our sun, or solar masses -- may have died unusually. In death, these objects -- among the universe's first generation of stars -- would have exploded as supernovae and burned completely, leaving no remnant black hole behind.
A new study finds that the Greenland Ice Sheet, which covers 1.7 million square kilometers and contains enough ice to raise sea levels worldwide by seven meters, is less stable and more sensitive to climate change than previously thought.
Truffles, along with caviar, are among the most expensive foods in the world. Because they grow underground, people use trained dogs or pigs to find them. But the distinctive smell of truffles is not only of interest to gourmets. A group of scientists have discovered that the smell of white truffles is largely produced by soil bacteria which are trapped inside truffle fruiting bodies.
Physicist have develop ultra-fast semiconductor nano-lasers. One thousand billion operations per second – this peak value has now been achieved by semiconductor nano-lasers.
Inspired perhaps by Harry Potter's invisibility cloak, scientists have recently developed several ways -- some simple and some involving new technologies -- to hide objects from view. The latest effort not only overcomes some of the limitations of previous devices, but it uses inexpensive, readily available materials in a novel configuration.
