Feeding fusion: Hydrogen ice pellets prove effective for fueling fusion plasmas

Injecting pellets of hydrogen ice rather than puffing hydrogen gas improves fusion performance. Studies by physicists compared the two methods on the DIII-D National Fusion Facility, looking ahead to the fueling to be used on ITER. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2020/03/200310164739.htm

Injection strategies are crucial for geothermal projects

The fear of earthquakes is one of the main reasons for reservations about geothermal energy. In order to get hot water from the depths, crevices in the rock underground often have to be created. This is done by injecting large quantities of water under high pressure. The problem is that such hydraulic stimulation is accompanied by vibrations in the underground, known as ''induced seismicity''. A new study from the now points a way that could help to reduce the seismic risk. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2020/03/200310114715.htm

Earth's mantle, not its core, may have generated planet's early magnetic field

A trio of studies are the latest developments in a paradigm shift that could change how Earth history is understood. They support an assertion by a geophysicist that a once-liquid portion of the lower mantle, rather than the core, could have exceeded the thresholds needed to create Earth's magnetic field during its early history. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2020/03/200315102257.htm

Scalable system for producing promising 2D material

Researchers have designed a system that can be used to make large quantities of the material while preserving its unique properties. The team recently reported that a lab-scale reactor system developed at the Materials Research Center in Kyiv, can convert a ceramic precursor material into a pile of the powdery black MXene titanium carbide, in quantities as large as 50 grams per batch. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2020/03/200310094235.htm

Modern virtual and augmented reality device can help simulate sight loss

A new study demonstrates how commercially available head mounted displays (HMD) can be used to simulate the day-to-day challenges faced by people with sight loss from glaucoma. The study suggests potential applications of the technology could include helping policymakers better assess the impact of visual impairment on patients, and helping architects to design more accessible buildings. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2020/03/200310094229.htm

Robots that admit mistakes foster better conversation in humans

A new study showed that the humans on teams that included a robot expressing vulnerability communicated more with each other and later reported having a more positive group experience than people teamed with silent robots or with robots that made neutral statements, like reciting the game's score. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2020/03/200309152047.htm

Atomic force microscopy: New sensing element for high-speed imaging

With atomic force microscopy, tiny structures can be imaged. But usually there is a trade of: In order to create pictures quickly, very stiff materials have to be used in the microscope, but they can damage delicate structures such as living cells. Scientists have now found a way around this dilemma. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2020/03/200305132130.htm

Exciting tweaks for organic solar cells

A molecular tweak has improved organic solar cell performance, bringing us closer to cheaper, efficient, and more easily manufactured photovoltaics. The new design approach targets the molecular backbone of the cell's power-generating layer. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2020/03/200305132202.htm

Safety zone saves giant moons from fatal plunge

Numerical simulations showed that the temperature gradient in the disk of gas around a young gas giant planet could play a critical role in the development of a satellite system dominated by a single large moon, similar to Titan around Saturn. Researchers found that dust in the circumplanetary disk can create a 'safety zone,' which keeps the moon from falling into the planet as the system evolves. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2020/03/200309110250.htm

A filter for cleaner qubits

Researchers show theoretically how coupling an additional filter qubit to the control line of a quantum computer can greatly increase the lifetime of the information stored in it. This work can help make quantum computers more robust and accurate. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2020/03/200306122604.htm

More accurate climate change model reveals bleaker outlook on electricity, water use

A new model more accurately captures how climate change will impact electricity and water use. The researchers recommend that city planners use the model now to better evaluate potential risk of power shortages and blackouts. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2020/03/200305203523.htm

Machine sucks up tiny tissue spheroids and prints them precisely

A new method of bioprinting uses aspiration of tiny biologics such as spheroids, cells and tissue strands, to precisely place them in 3D patterns either on scaffolding or without to create artificial tissues with natural properties, according to researchers. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2020/03/200307203052.htm

Cosmic impact caused destruction of one of world's earliest human settlements

Before the Taqba Dam impounded the Euphrates River in northern Syria in the 1970s, an archaeological site named Abu Hureyra bore witness to the moment ancient nomadic people first settled down and started cultivating crops. A large mound marks the settlement, which now lies under Lake Assad. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2020/03/200306183153.htm
