![]() | Scientists demonstrate a new experiment in the search for theorized 'neutrinoless' procNuclear physicists affiliated with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) played a leading role in analyzing data for a demonstration experiment that has achieved record precision for a specialized detector material. |
![]() | Tiny bubbles make a quantum leapJuly 13, 2020—Researchers at Columbia Engineering and Montana State University report today that they have found that placing sufficient strain in a 2-D material—tungsten diselenide (WSe2)—creates localized states that can yield single-photon emitters. Using sophisticated optical microscopy techniques developed at Columbia over the past three years, the team was able to directly image these states for the first time, revealing that even at room temperature they are highly tunable and act as quantum dots, tightly confined pieces of semiconductors that emit light. |
![]() | New technique to study superheavy elementsSuperheavy elements are intriguing nuclear and atomic quantum systems that challenge experimental probing as they do not occur in nature and, when synthesized, vanish within seconds. Pushing the forefront of atomic physics research to these elements requires breakthrough developments towards fast atomic spectroscopy techniques with extreme sensitivity. A joint effort within the European Union's Horizon 2020 Research and Innovation program and led by Dr. Mustapha Laatiaoui from Johannes Gutenberg University Mainz (JGU) culminated in an optical spectroscopy proposal: The so-called Laser Resonance Chromatography (LRC) should enable such investigations even at minute production quantities. The proposal has recently been published in two articles in Physical Review Letters and Physical Review A. |
![]() | Scientists have discovered a new physical paradoxResearchers from the Peter the Great St.Petersburg Polytechnic University (SPbPU) have discovered and theoretically explained a new physical effect: amplitude of mechanical vibrations can grow without external influence. The scientific group offered their explanation on how to eliminate the Fermi-Pasta-Ulam-Tsingou paradox. |
Astronomy and Space news
![]() | Structure of the molecular cloud Orion A investigated in detailUsing a 3-D mapping technique, astronomers from Sweden and Germany have explored a nearby molecular cloud known as Orion A. The new study unveils more details about the structure and nature of this cloud. The research was presented in a paper published July 6 on the arXiv pre-print repository. |
![]() | Artificial intelligence predicts which planetary systems will surviveWhy don't planets collide more often? How do planetary systems—like our solar system or multi-planet systems around other stars—organize themselves? Of all of the possible ways planets could orbit, how many configurations will remain stable over the billions of years of a star's life cycle? |
![]() | The quest to find signs of ancient life on MarsMars may now be considered a barren, icy desert but did Earth's nearest neighbour once harbour life? |
![]() | Researchers find younger age for Earth's moonThe moon formed a little later than previously assumed. When a Mars-sized protoplanet was destroyed in a collision with the young Earth, a new body was created from the debris ejected during this collision, which became the moon. Planetary geophysicists at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), led by Maxime Maurice, together with researchers at the University of Münster, have used a new numerical model to reconstruct the time at which the event occurred—4.425 billion years ago. The previous assumptions about the formation of the moon were based on an age of 4.51 billion years—that, is 85 million years earlier than the new calculations reveal. The scientists have reported their findings in Science Advances. |
![]() | Parker Solar Probe spies newly discovered comet NEOWISENASA's Parker Solar Probe was at the right place at the right time to capture a unique view of comet NEOWISE on July 5, 2020. Parker Solar Probe's position in space gave the spacecraft an unmatched view of the comet's twin tails when it was particularly active just after its closest approach to the sun, called perihelion. |
![]() | Astronomers map massive structure beyond Laniakea SuperclusterFor the past decade, an international team of astronomers, led in part by Brent Tully at the University of Hawaiʻi Institute for Astronomy, has been mapping the distribution of galaxies around the Milky Way. They have discovered an immense structure beyond Laniakea, an immense supercluster of galaxies, including our own. Astronomers have dubbed the newly identified structure the South Pole Wall. |
![]() | Why lava tubes should be our top exploration priority on other worldsWhen magma comes out of the Earth onto the surface, it flows as lava. Those lava flows are fascinating to watch, and they leave behind some unique landforms and rocks. But a lot of what's fascinating about these flows can be hidden underground as lava tubes. |
![]() | About eight percent of red giants are covered by sunspot-like dark areas.Starspots are more common among red giant stars than previously thought. In the journal Astronomy & Astrophysics, researchers led by the Max Planck Institute for Solar System Research (MPS) in Germany report that approximately eight percent of red giants exhibit such spots. They are the expression of strong magnetic fields at the stellar surface. These magnetic fields are created deep inside the star in a process that requires, among other things, convection and a fast rotation of the star. Although red giants are generally regarded as slowly rotating stars, those with starspots are apparently an exception. The new publication offers a comprehensive analysis of the reasons for their short rotation periods ranging from forced synchronization with another, closely neighboring star, to the swallowing of a star or planet, to a fast initial rotation speed in an early phase of development. |

![]() | Astrophysicists suggest carbon found in comet ATLAS help reveal age of other cometsAstrophysicists from Far Eastern Federal University (FEFU, Russia), South Korea, and the U.S. appear in Monthly Notices of the Royal Astronomical Society, suggesting carbon indicates time comets have spent in the Solar System—the less carbon, the longer they have been in the proximity of the Sun. The proof is their study of the comet ATLAS (C/2019 Y4) approaching the Earth in May 2020 and disintegrated with displaying a major outbreak of the carbonaceous particles. |

![]() | Understanding the love-hate relationship of halide perovskites with the sunSolar cells made of perovskite are at the center of much recent solar research. The material is cheap, easy to produce, and almost as efficient as silicon, the material traditionally used in solar cells. However, perovskite cells have a love-hate relationship with the sun. The light that they need to generate electricity, also impairs the quality of the cells, severely limiting their efficiency and stability over time. Research by scientists at the Eindhoven University of Technology and universities in China and the U.S. now sheds new light on the causes of this degradation and paves the way for designing new perovskite compositions for the ultimate stable solar cells. |
![]() | Gaze-controlled robotic arm for the speech and motor impairedPeople with severe speech and motor impairment (SSMI), a condition caused by disorders like cerebral palsy, have difficulty physically operating devices such as a joystick, mouse or trackball, or use speech recognition systems.

![]() | Mini-LED, Micro-LED, and OLED displays: Present status and future perspectivesDisplay technology has become ubiquitous in our daily life; its widespread applications cover smartphones, tablets, desktop monitors, TVs, data projectors, and augmented reality/virtual reality devices. Presently, liquid crystal displays (LCDs) and organic light-emitting diode (OLED) displays are two dominant flat panel display technologies. Recently, inorganic mini-LEDs (mLEDs) and micro-LEDs (μLEDs) are emerging, offering ultrahigh luminance and long lifetimes, that can significantly enhance the dynamic range of LCDs or work as sunlight readable emissive displays. Nevertheless, challenges such as mass transfer yield and defect repair remain, which will undoubtedly affect the cost. "LCD, OLED or μLED: who wins?" has become a topic of heated debate. |
![]() | Wanted: The best storage batteryThe global economy's demand for lithium-ion batteries will be rising sharply in the future. Electric cars depend on them, as do laptops, smartphones and power tools for the construction industry and the DIY sector. Soon another area will follow suit that requires rechargeable batteries at an even larger scale: the storage of renewable energy. |
