Scalable global quantum gates on arbitrary ion-qubits

The ion-trap quantum computation research group led by Professor Kihwan Kim in the Center of Quantum Information, Institute of Interdisciplinary Information (IIIS), Tsinghua University, has recently proposed and successfully demonstrated powerful more than two-qubit quantum gate operations in a trapped ion system. The work “Quantum Simulation of the Quantum Rabi Model in a Trapped Ion” … Read more

Underwater glacial melting is occurring at higher rates than modeling predicts

Researchers have developed a new method to allow for the first direct measurement of the submarine melt rate of a tidewater glacier, and, in doing so, they concluded that current theoretical models may be underestimating glacial melt by up to two orders of magnitude. In a National Science Foundation-funded project, a team of scientists, led … Read more

High-performance flow batteries offer path to grid-level renewable energy storage

A low-cost, high-performance battery chemistry developed by University of Colorado Boulder researchers could one day lead to scalable grid-level storage for wind and solar energy that could help electrical utilities reduce their dependency on fossil fuels. The new innovation, described today in the journal Joule, outlines two aqueous flow batteries, also known as redox flow batteries, … Read more

A tree stump that should be dead is still alive; here’s why

Within a shrouded New Zealand forest, a tree stump keeps itself alive by holding onto the roots of its neighboring trees, exchanging water and resources through the grafted root system. New research, publishing July 25 in iScience, details how surrounding trees keep tree stumps alive, possibly in exchange for access to larger root systems. The findings … Read more

Little helpers for the rainforest

Tropical rainforests store large quantities of carbon dioxide, produce oxygen and provide habitats for many animal and plant species. If these ecosystems, which are so important for the global climate and biodiversity, are destroyed, they will recover very slowly, if at all. Scientists from the German Primate Center (DPZ) – Leibniz Institute for Primate Research, … Read more

Supercomputers use graphics processors to solve longstanding turbulence question

When a fluid, such as water or air, flows fast enough, it will experience turbulence – seemingly random changes in velocity and pressure within the fluid. Turbulence is extremely difficult to study but is important for many fields of engineering, such as air flow past wind turbines or jet engines. Understanding turbulence better would allow … Read more

Shape shifting protocells hint at the mechanics of early life

Inspired by the processes of cellular differentiation observed in developmental biology, an interdisciplinary team of researchers at the University of Bristol have demonstrated a new spontaneous approach to building communities of cell-like entities (protocells) using chemical gradients. In a new study published today in the journal Nature Communications, Professor Stephen Mann from Bristol’s School of Chemistry, … Read more

The geoengineering of consent: How conspiracists dominate YouTube climate science content

Using YouTube to learn about climate-change-related topics will expose you to video content that mostly opposes worldwide scientific consensus. That’s the finding of a new study published in Frontiers in Communication, which also reveals that some scientific terms, such as geoengineering, have been ‘hijacked’ by conspiracy theorists so that searches provide entirely non-scientific video content. Scientists … Read more
