Researchers make a quantum computing leap with a magnetic twist      (via sciencedaily.com)     Original source 

Scientists and engineers have announced a significant advancement in developing fault-tolerant qubits for quantum computing. In a pair of articles, they report that, in experiments with flakes of semiconductor materials -- each only a single layer of atoms thick -- they detected signatures of 'fractional quantum anomalous Hall' (FQAH) states. The team's discoveries mark a first and promising step in constructing a type of fault-tolerant qubit because FQAH states can host anyons -- strange 'quasiparticles' that have only a fraction of an electron's charge. Some types of anyons can be used to make what are called 'topologically protected' qubits, which are stable against any small, local disturbances.

Research in a place where geological processes happen before your eyes      (via sciencedaily.com)     Original source 

Taiwan experiences some of the world's fastest rates of mountain building -- they are growing at a faster rate than our fingernails grow in a year. The mountains also see frequent and significant earthquakes, the region experiences about four typhoons per year on average, and in some places, it receives upwards of several meters of rain annually.

Act now to prevent uncontrolled rise in carbon footprint of computational science      (via sciencedaily.com)     Original source 

Scientists have set out principles for how computational science -- which powers discoveries from unveiling the mysteries of the universe to developing treatments to fight cancer to improving our understanding of the human genome, but can have a substantial carbon footprint -- can be made more environmentally sustainable.

Study of Earth's stratosphere reduces uncertainty in future climate change      (via sciencedaily.com)     Original source 

New research reduces uncertainty in future climate change linked to the stratosphere, with important implications for life on Earth. A significant source of uncertainty relates to future changes to water vapor in the stratosphere, an extremely dry region of the atmosphere 15--50 km above the Earth's surface. Future increases in water vapor here risk amplifying climate change and slowing down the recovery of the ozone layer, which protects life on Earth from harmful solar ultraviolet radiation.

Study of deep-sea corals reveals ocean currents have not fuelled rise in atmospheric carbon dioxide      (via sciencedaily.com)     Original source 

Pioneering analysis of deep-sea corals has overturned the idea that ocean currents contributed to increasing global levels of carbon dioxide in the air over the past 11,000 years.

Effect of volcanic eruptions significantly underestimated in climate projections      (via sciencedaily.com)     Original source 

Researchers have found that the cooling effect that volcanic eruptions have on Earth's surface temperature is likely underestimated by a factor of two, and potentially as much as a factor of four, in standard climate projections.

Are viruses keeping sea lice at bay in wild salmon?      (via sciencedaily.com)     Original source 

More than 30 previously unknown RNA viruses in sea lice have been identified. Sea lice are parasitic copepods (small crustaceans) found in many fresh and saltwater habitats, and have been implicated in the decline of wild salmon populations. The research sheds greater light on the types of viruses being carried by sea lice, and how the viruses and host are interacting.
