Electronic circuits are based on electrons, but one of the most promising technologies for future quantum circuits are photonic circuits, i.e. circuits based on light (photons) instead of electrons. First, it is necessary to be able to create a stream of single photons
New NASA research shows that Earth's atmosphere contains an unexpectedly large amount of an ozone-depleting compound – Carbon tetrachloride (CCl4) – from an unknown source decades after the compound was banned worldwide.Carbon tetrachloride was regulated
A new study by scientists from Oregon State University, published this week in journal Science, concludes that sunlight and not bacteria is the key to triggering the production of CO2 from material released by Arctic soils. The finding is particularly importan
A new study from Lund University in Sweden has, for the first time, reconstructed solar activity during the last ice age and showed that the regional climate is influenced by the Sun.For the first time, a research team has been able to reconstruct the solar activit
Over the past one hundred thousand years cold temperatures largely prevailed over the planet in what is known as the last ice age. However, the cold period was repeatedly interrupted by much warmer climate conditions. Scientists have long attempted to find out why these
A team of scientists has been combing through the payload of NASA's Stardust spacecraft since it returned to Earth in 2006. They found seven rare, microscopic interstellar dust particles, that most likely came from outside of our solar system. If
Pharmaceuticals, personal-care products, and other contaminants are widespread in water that has passed through landfill waste. The samples of this liquid, also known as leachate, were collected from within each of the studied landfills. This study by the U.S. Geol
Sections of Antarctica's frozen desert can experience hundreds of micro-quakes an hour due to ice deformation. These quakes are also called icequakes and they are a usual occurrence on Antarctica. However, after the 8.8-magnitude earthquake that hit C
Physicists at The Australian National University (ANU) have created a tractor beam on water, providing a radical new technique that could confine oil spills, manipulate floating objects or explain rips at the beach.The group, led by Professor Michael Shats discovered th
Taking the human-machine concept to an unprecedented level, pioneering scientists are working on the seamless marriage between electronics and brain signaling with the potential to transform our understanding of how the brain works — and how to treat its most
