 | MATRIEX imaging: Simultaneously seeing neurons in action in multiple regions of the brainTwo-photon laser scanning microscopy imaging is commonly applied to study neuronal activity at cellular and subcellular resolutions in mammalian brains. Such studies are yet confined to a single functional region of the brain. In a recent report, Mengke Yang and colleagues at the Brain Research Instrument Innovation Center, Institute of Neuroscience, Center for Systems Neuroscience and Optical System Advanced Manufacturing Technology in China, Germany and the U.K. developed a new technique named the multiarea two-photon real-time in vitro explorer (MATRIEX). The method allowed the user to target multiple regions of the functional brain with a field of view (FOV) approximating 200 µm in diameter to perform two-photon Ca2+ imaging with single-cell resolution simultaneously across all regions. |
 | First chip-to-chip quantum teleportation harnessing silicon photonic chip fabricationThe development of technologies which can process information based on the laws of quantum physics are predicted to have profound impacts on modern society. |
 | Large-area and flexible near-infrared light-emitting diodesInfrared LEDs are useful for optical communications and covert illumination, and are commonly found in remote controls and security camera setups. They are generally small point sources, which limits their use if larger-area illumination is required in close proximity, for instance, on a wearable device. |
 | Synthetic magnetism leads photons on a 2-D quantum walkRandomness governs many things, from the growth of cell colonies and the agglomeration of polymers to the shapes of tendrils that form when you pour cream into a cup of coffee. |
 | Lasers learn to accurately spot space junkChinese researchers have improved the accuracy in detecting space junk in earth's orbit, providing a more effective way to plot safe routes for spacecraft maneuvers. |
Astronomy & Space news
 | LAMOST first data release provides fundamental parameters of nearly 30,000 M dwarfsBased on the first data release (DR1) from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), astronomers have derived fundamental parameters of nearly 30,000 M-dwarf stars. The research paper presenting the findings was published December 13 on the arXiv pre-print repository. |
 | Astronomers describe a violent black hole outburst that provides new insight into galaxy cluster evolutionBillions of years ago, in the center of a galaxy cluster far, far away (15 billion light-years, to be exact), a black hole spewed out jets of plasma. As the plasma rushed out of the black hole, it pushed away material, creating two large cavities 180 degrees from each other. In the same way you can calculate the energy of an asteroid impact by the size of its crater, Michael Calzadilla, a graduate student at the MIT Kavli Institute for Astrophysics and Space Research (MKI), used the size of these cavities to figure out the power of the black hole's outburst. |
 | Researchers make new discoveries set to reveal the geology of planets outside our solar systemThree OU astronomers today announced groundbreaking discoveries allowing scientists to understand planets outside the solar system. Professor Carole Haswell, Dr. Daniel Staab and Dr. John Barnes discovered three, new, nearby planetary systems. |
 | Our favorite holiday gift? A box of Apollo moon soilFortunately for today's scientists, Apollo-era leaders had the foresight to save much of the 842 pounds (382 kilograms) of Moon soil and rocks retrieved by NASA astronauts 50 years ago for future generations. They figured new crops of scientists, using instruments of their time, would be able to probe the samples with unprecedented rigor. |
 | The citizen scientists who helped map BennuWhen NASA's OSIRIS-REx mission spacecraft arrived at the asteroid Bennu, it discovered more rocks and boulders than envisioned. Mapping all these potential hazards was necessary to select a location to collect a sample of the surface for return to Earth. This effort was the work of multiple teams around the globe. One of those teams consisted of more than 3,500 citizen scientists who used CosmoQuest's Bennu Mappers project to mark rocks, measure boulders, and map craters. Together, they made more than 14 million annotations of features on a global map of Bennu. CosmoQuest is a project that is based at the Planetary Science Institute in Tucson, Ariz. (CosmoQuest.org). |
Technology news
 | AD-EYE: A co-simulation platform to verify functional safety concepts (FSCs) in self-driving vehiclesOver the past few years, a growing number of researchers and companies worldwide have been developing techniques for automated driving. Before self-driving vehicles can be introduced on real roads, however, their efficiency and safety will need to be ascertained. |
 | High-performance anode for all-solid-state lithium batteries is made of silicon nanoparticlesA new study led by NIMS researchers reveals that in solid electrolytes, a silicon anode composed only of commercial silicon nanoparticles prepared by spray deposition exhibits excellent electrode performance, which has previously been observed only for film electrodes prepared by evaporation processes. The method is a cost-effective, atmospheric technique, and his new result therefore suggests that a low-cost and large-scale production of high-capacity anodes for use in all-solid-state lithium batteries is possible. |
 | How technology made us bid farewell to privacy in the last decadeIn 2011, Apple unveiled its first iPhone with artificial intelligence, a personal assistant named Siri that could answer questions and help keep track of our daily lives. |
 | Uber co-founder Travis Kalanick severs last ties to companyAbout decade after co-founding Uber, Travis Kalanick on Tuesday severed his last ties from the ride-hailing giant, announcing he would exit the board of directors at the end of 2019. |
 | Boeing document dump shows 'disturbing' picture on 737 MAX: officialBoeing provided a fresh batch of incriminating documents on the 737 MAX to regulators and congressional investigators, only hours after announcing a leadership shakeup, officials confirmed Tuesday. |
