 | New research synthesizes different aspects of causality in quantum field theoryIn current quantum field theory, causality is typically defined by the vanishing of field commutators for spacelike separations. Two researchers at the University of Massachusetts and Universidade Federal Rural in Rio de Janeiro have recently carried out a study discussing and synthesizing some of the key aspects of causality in quantum field theory. Their paper, published in Physical Review Letters, is the result of their investigation of a theory of quantum gravity commonly referred to as "quadratic gravity." |
 | Machine learning enhances light-beam performance at the advanced light sourceSynchrotron light sources are powerful facilities that produce light in a variety of "colors," or wavelengths—from the infrared to X-rays—by accelerating electrons to emit light in controlled beams. |
 | Researchers convert 2-D images into 3-D using deep learningA UCLA research team has devised a technique that extends the capabilities of fluorescence microscopy, which allows scientists to precisely label parts of living cells and tissue with dyes that glow under special lighting. The researchers use artificial intelligence to turn two-dimensional images into stacks of virtual three-dimensional slices showing activity inside organisms. |
 | Blurry imaging limits clarified thanks to information technologyAlthough we're told a picture speaks a thousand words, that cliché seriously underestimates the value of a good image. Our understanding of how the world works is simplified by our ability to turn data into images. Imaging is at the heart of science: if it can be measured, it will be turned into an image to be analyzed. |
 | A new way to measure gravity: Using floating atomsA team of researchers at the University of California, Berkeley, has found a new way to measure gravity—by noting differences in atoms in a supposition state, suspended in the air by lasers. In their paper published in the journal Science, the group describes their new technique and explain why they believe it will be more useful than traditional methods. |
 | Photosynthesis seen in a new light by rapid X-ray pulsesThe ability to transform sunlight into energy is one of Nature's more remarkable feats. Scientists understand the basic process of photosynthesis, but many crucial details remain elusive, occurring at dimensions and fleeting time scales long deemed too minuscule to probe. |
 | Century-old food testing method updated to include complex fluid dynamicsThe texture of food, including properties that determine how consumers experience biting and swallowing, is an important part of development of more enjoyable foods. In order to completely understand these properties, better methods and devices for testing are required to capture the motion inside liquid materials, especially in the case of foods that are complex liquids, like gelled desserts. |
 | A new type of fire, the fuel of the future?Later this month a Texus rocket will launch from Esrange, Sweden, that will travel about 260 km upwards and fall back to Earth offering researchers six minutes of zero gravity. Their experiment? Burning metal powder to understand a new type of fire. |
 | A new quantum data classification protocol brings us nearer to a future 'quantum internet'Quantum-based communication and computation technologies promise unprecedented applications, such as unconditionally secure communications, ultra-precise sensors, and quantum computers capable of solving specific problems with a level of efficiency impossible to reach by classical computers. In recent times, quantum computers are also envisioned as nodes in a network of quantum devices, where connections are established via quantum channels and data are quantum systems that flow through the network, thus setting the bases for a future "quantum internet." |
Astronomy & Space news
 | Scientists further refine how quickly the universe is expandingWielding state-of-the-art technologies and techniques, a team of Clemson University astrophysicists has added a novel approach to quantifying one of the most fundamental laws of the universe. |
 | Mercury putting on rare show Monday, parading across the sunMercury is putting on a rare celestial show next week, parading across the sun in view of most of the world. |
 | Rare transit of Mercury to take place on 11 NovemberA rare transit of Mercury will take place on 11 November, when the smallest planet in our Solar System will pass directly between the Earth and the Sun. The last time this happened was in 2016, and the next will be in 2032. During the transit, which takes place in the afternoon in the UK, Mercury will appear as a dark silhouetted disc set against the bright surface of the Sun. |
 | Researchers investigate interstellar bodies originating from beyond our solar systemAstonishingly, not one but two interstellar asteroids have been detected entering our solar system since 2017. |
 | NASA's Mars 2020 heads into the test chamberIn this time-lapse video, taken on Oct. 9, 2019, at NASA's Jet Propulsion Laboratory in Pasadena, California, bunny-suited engineers move the Mars 2020 rover from a high bay in the Spacecraft Simulator Building into the facility's large vacuum chamber for testing in Mars-like environmental conditions. |
 | NASA instrument to probe planet clouds on European missionNASA will contribute an instrument to a European space mission that will explore the atmospheres of hundreds of planets orbiting stars beyond our Sun, or exoplanets, for the first time. |
 | Image: Suitcase-sized asteroid explorerThis replica model of ESA's 'Miniaturised Asteroid Remote Geophysical Observer', or M-Argo, was on display at the Agency's recent Antennas workshop. It is the one of numerous small missions planned as part of ESA's Technology Strategy, being presented at this month's Space19+ Council at Ministerial Level. |

 | Beyond lithium-ion: next generation battery research underwayNew smartphones, portable devices and electric cars may get a lot of the public's attention but all of them are dependent on batteries to make them run. Most current devices use rechargeable lithium-ion batteries—technology that was first commercialized in the early 1990s. Lithium-ion batteries offered a longer life span, improved discharge and better efficiency over older rechargeable batteries but also come with some notable disadvantages. Lithium can be relatively expensive and difficult to recycle, and lithium-based batteries can have issues with overheating. |
