Spintronics: Faster data processing through ultrashort electric pulses Posted: 02 Jul 2020 07:05 AM PDT Physicists have developed a simple concept that could improve significantly magnetic-based data processing. Using ultrashort electric pulses in the terahertz range, data can be written, read and erased very quickly. This would make data processing faster, more compact and energy efficient. The researchers confirmed their theory by running complex simulations.

Ion conducting polymer crucial to improving neuromorphic devices Posted: 01 Jul 2020 01:29 PM PDT ''Neuromorphic'' refers to mimicking the behavior of brain neural cells. When one speaks of neuromorphic computers, they are talking about making computers think and process more like human brains-operating at high-speed with low energy consumption.

Beacon from the early universe Posted: 01 Jul 2020 01:01 PM PDT Often described as cosmic lighthouses, quasars are luminous beacons that can be observed at the outskirts of the Universe, providing a rich topic of study for astronomers and cosmologists. Now scientists have announced the discovery of the second-most distant quasar ever found, at more than 13 billion lightyears from Earth.

Higher concentration of metal in Moon's craters provides new insights to its origin Posted: 01 Jul 2020 12:17 PM PDT Life on Earth would likely not be possible without the Moon; it keeps our planet's axis of rotation stable, which controls seasons and regulates our climate. However, there has been considerable debate over how the Moon was formed. The popular hypothesis contends that the Moon was formed by a Mars-sized body colliding with Earth's upper crust which is poor in metals. But new research suggests the Moon's subsurface is more metal-rich than previously thought, providing new insights that could challenge our understanding of that process.

Jellyfish-inspired soft robots can outswim their natural counterparts Posted: 01 Jul 2020 12:17 PM PDT Engineering researchers have developed soft robots inspired by jellyfish that can outswim their real-life counterparts. More practically, the new jellyfish-bots highlight a technique that uses pre-stressed polymers to make soft robots more powerful.

New system combines smartphone videos to create 4D visualizations Posted: 01 Jul 2020 10:42 AM PDT Researchers have demonstrated that they can combine iPhone videos shot 'in the wild' by separate cameras to create 4D visualizations that allow viewers to watch action from various angles, or even erase people or objects that temporarily block sight lines.

Elucidating how asymmetry confers chemical properties Posted: 01 Jul 2020 09:54 AM PDT New research categorizes the causes of structural asymmetry, some surprising, which underpin useful properties of crystals, including ferroelectricity, photoluminescence, and photovoltaic ability.

Energy-saving servers: Data storage 2.0 Posted: 01 Jul 2020 09:54 AM PDT A research team has developed a technique that will potentially halve the energy required to write data to servers and make it easier to construct complex server architectures.

Coordinating complex behaviors between hundreds of robots Posted: 01 Jul 2020 09:54 AM PDT Researchers propose a new approach to finding an optimal solution for controlling large numbers of robots collaboratively completing a set of complex linear temporal logic commands called STyLuS*, for large-Scale optimal Temporal Logic Synthesis, that can solve problems massively larger than what current algorithms can handle, with hundreds of robots, tens of thousands of rooms and highly complex tasks, in a small fraction of the time.

First exposed planetary core discovered allows glimpse inside other worlds Posted: 01 Jul 2020 09:54 AM PDT The surviving core of a gas giant has been discovered orbiting a distant star, offering an unprecedented glimpse into the interior of a planet.

Materials scientists drill down to vulnerabilities involved in human tooth decay Posted: 01 Jul 2020 09:54 AM PDT Researchers have cracked one of the secrets of tooth decay. The materials scientists are the first to identify a small number of impurity atoms in human enamel that may contribute to the material's strength but also make it more soluble. They also are the first to determine the spatial distribution of the impurities with atomic-scale resolution. The discovery could lead to a better understanding of human tooth decay as well as genetic conditions that affect enamel formation.

A binary star as a cosmic particle accelerator Posted: 01 Jul 2020 07:01 AM PDT Scientists have identified the binary star Eta Carinae as a new kind of source for very high-energy (VHE) cosmic gamma-radiation. Eta Carinae is located 7500 lightyears away in the constellation Carina in the Southern Sky and, based on the data collected, emits gamma rays with energies up to 400 gigaelectronvolts (GeV), some 100 billion times more than the energy of visible light.

Toward principles of gene regulation in multicellular systems? Posted: 01 Jul 2020 07:00 AM PDT Quantitative biologists ombine precision measurements and mathematical models to uncover a common mechanism regulating gene expression during development.

Scientists use a Teflon pipe to make a cheap, simple reactor for silica particle synthesis Posted: 01 Jul 2020 07:00 AM PDT The synthesis of silica particles, used in bioimaging and drug delivery, could become considerably cheaper and more efficient by adopting a new flow synthesis method which involves a spiral channel and simple Teflon pipe to promote the rapid mixing of precursor fluids.

Building a harder diamond Posted: 01 Jul 2020 07:00 AM PDT Scientists create a theoretical carbon-based material that would be even harder than diamond. This work may have industrial applications for cutting and polishing in place of current synthetic diamond.

Material research: New chemistry for ultra-thin gas sensors Posted: 01 Jul 2020 07:00 AM PDT The application of zinc oxide layers in industry is manifold and ranges from the protection of degradable goods to the detection of toxic nitrogen oxide gas. Such layers can be deposited by atomic layer deposition (ALD) which employs typically chemical compounds, or simply precursors, which ignite immediately upon contact with air, i.e. are highly pyrophoric.

Tabletop quantum experiment could detect gravitational waves Posted: 01 Jul 2020 07:00 AM PDT Tiny diamond crystals could be used as an incredibly sensitive and small gravitational detector capable of measuring gravitational waves, suggests new research.

Hidden sources of mysterious cosmic neutrinos seen on Earth Posted: 01 Jul 2020 05:47 AM PDT A new model points to the coronoe of supermassive black holes at the cores of active galaxies to help explain the excess neutrinos observed by the IceCube Neutrino Observatory.
