A cosmic object originally classified as a gas and dust cloud actually consists of three stars and could resolve a controversy among astronomers. In 2011, an object was found by means of the infrared data measured by the Very Large Telescope, promising to reveal an unprecedented process at the centre of our galaxy. Based on…

Researchers across the dark matter community that have begun to wonder if they are looking for the right type of dark matter. They have proposed a new way to look for the particles that might make up dark matter by repurposing existing tabletop sensor technology. University of Delaware’s Swati Singh is among a small group…

Nuclear power plants can withstand most inclement weather and do not emit harmful greenhouse gases. However, trafficking of the nuclear materials to furnish them with fuel remains a serious issue as security technology continues to be developed. Physicists conducted research to enhance global nuclear security by improving radiation detectors. According to them, improving radiation detectors…

Researchers have used a unique tool inserted into an electron microscope to create a transistor that’s 25,000 times smaller than the width of a human hair. The research, published in the journal Science, involves researchers from Japan, China, Russia and Australia who have worked on the project that began five years ago. QUT Centre for…

Spin waves could unlock the next generation of computer technology, a new component allows physicists to control them. Traditional electronics uses electrical charge to carry out computations that power most of our day-to-day technology. However, engineers are unable to make electronics do calculations faster, as moving charge creates heat, and we’re at the limits of…

Bilayer graphene with one of the two layers twisted displayed unique resonant electronic behavior. Understanding how electrons move in such 2-D materials could shed light on how to manipulate them for quantum computing and communication. «Today’s computer chips are based on our knowledge of how electrons move in semiconductors, specifically silicon,» said first and co-corresponding…

Researchers have developed next-generation, graphene-based sensing technology using their innovative G-Putty material. The team’s printed sensors are 50 times more sensitive than the industry standard and outperform other comparable nano-enabled sensors in an important metric seen as a game-changer in the industry: flexibility. The team’s printed sensors are 50 times more sensitive than the industry…

An international team of researchers has published comprehensive data on the search for dark matter using a worldwide network of optical magnetometers. According to the scientists, dark matter fields should produce a characteristic signal pattern that can be detected by correlated measurements at multiple stations of the GNOME network. GNOME stands for Global Network of…

The movement of electrons can have a significantly greater influence on spintronic effects than previously assumed. Until now, a calculation of these effects took, above all, the spin of electrons into consideration. The study offers a new approach in developing spintronic components. Many technical devices are based on conventional semiconductor electronics. Charge currents are used…

Scientists found that ants and other natural systems use optimization algorithms similar to those used by engineered systems, including the Internet. These algorithms invest incrementally more resources as long as signs are encouraging but pull back quickly at the first sign of trouble. The systems are designed to be robust, allowing for portions to fail…
