Published Capturing hidden data for asymptomatic COVID-19 cases provides a better pandemic picture
(via sciencedaily.com) Asymptomatic COVID-19 cases are the bane of computer modelers' existences -- they throw off the modeling data to an unknown degree. A new approach explores using historic epidemic data from eight different countries to estimate the transmission rate and fraction of under-reported cases.
Published Future gravitational wave detector in space could uncover secrets of the Universe
(via sciencedaily.com) New research has shown that future gravitational wave detections from space will be capable of finding new fundamental fields and potentially shed new light on unexplained aspects of the Universe.
Published Saturn’s high-altitude winds generate an extraordinary aurorae, study finds
(via sciencedaily.com) Space scientists have discovered a never-before-seen mechanism fueling huge planetary aurorae at Saturn.
Published Satellites and light reflections help researchers spot coastal plastic waste
(via sciencedaily.com) Geospatial scientists have found a way to detect plastic waste on remote beaches that are not visible in conventional satellite images, bringing us closer to global monitoring options.
Published New computational tool predicts cell fates and genetic perturbations
(via sciencedaily.com) Researchers have built a machine learning framework that can define the mathematical equations describing a cell's trajectory from one state to another, such as its development from a stem cell into one of several different types of mature cell. The framework, called dynamo, can also be used to figure out the underlying mechanisms -- the specific cocktail of gene activity -- driving changes in the cell.
Published New control technique uses solar panels to reach desired Mars orbit
(via sciencedaily.com) Aerospace engineers have developed a way to use articulated solar panels to steer the satellite during aerobraking, reducing the number of passes needed, resulting in potential savings in propellant, time, and money.
Published Hubble finds a black hole igniting star formation in a dwarf galaxy
(via sciencedaily.com) Often portrayed as destructive monsters that hold light captive, black holes take on a less villainous role in the latest research from NASA's Hubble Space Telescope. A black hole at the heart of the dwarf galaxy Henize 2-10 is creating stars rather than gobbling them up. The black hole is apparently contributing to the firestorm of new star formation taking place in the galaxy. The dwarf galaxy lies 30 million light-years away, in the southern constellation Pyxis.
Published Enhanced statistical models will aid conservation of killer whales and other species
(via sciencedaily.com) Retrieving an accurate picture of what a tagged animal does as it journeys through its environment requires statistical analysis, especially when it comes to animal movement, and the methods statisticians use are always evolving to make full use of the large and complex data sets that are available. A recent study by researchers at the Institute for the Oceans and Fisheries (IOF) and the UBC department of statistics has taken us a step closer to understanding the behaviours of northern resident killer whales by improving statistical tools useful for identifying animal behaviours that can't be observed directly.
Published Being in space destroys more red blood cells
(via sciencedaily.com) Original source A world-first study has revealed how space travel can cause lower red blood cell counts, known as space anemia. Analysis of 14 astronauts showed their bodies destroyed 54 percent more red blood cells in space than they normally would on Earth, according to a new study.
Published New insights into seasons on a planet outside our solar system
(via sciencedaily.com) Imagine being in a place where the winds are so strong that they move at the speed of sound. That's just one aspect of the atmosphere on XO-3b, one of a class of exoplanets (planets outside our solar system), known as hot Jupiters. The eccentric orbit of the planet also leads to seasonal variations hundreds of times stronger than what we experience on Earth.
Published Rugby ball-shaped exoplanet discovered
(via sciencedaily.com) With the help of the CHEOPS space telescope, an international team was able to detect the deformation of an exoplanet for the first time. Due to strong tidal forces, the appearance of the planet WASP-103b resembles a rugby ball rather than a sphere.
Published NASA's Webb Telescope reaches major milestone as mirror unfolds
(via sciencedaily.com) Original source NASA's James Webb Space Telescope team fully deployed its 21-foot, gold-coated primary mirror, successfully completing the final stage of all major spacecraft deployments to prepare for science operations.
Published Sunshield successfully deploys on NASA's next flagship telescope
(via sciencedaily.com) The James Webb Space Telescope team has fully deployed the spacecraft's 70-foot sunshield, a key milestone in preparing it for science operations.
Published NASA's Webb telescope launches to see first galaxies, distant worlds
(via sciencedaily.com) NASA's James Webb Space Telescope launched Dec. 25 from Europe's Spaceport in French Guiana, South America. The Webb observatory's mission is to seek the light from the first galaxies in the early universe and to explore our own solar system, as well as planets orbiting other stars, called exoplanets.
Published Are black holes and dark matter the same?
(via sciencedaily.com) Astrophysicists suggest that primordial black holes account for all dark matter in the universe.
Published How statistics can aid in the fight against misinformation
(via sciencedaily.com) Mathematicians created a statistical model that can be used to detect misinformation in social posts.
Published Grouping of immune cell receptors could help decode patients' personal history of infection
(via sciencedaily.com) Novel software for grouping immunological T-cell receptors may enable the identification of shared patterns that could be used to determine if a person has previously been infected or vaccinated against a given pathogen.
Published Closest pair of supermassive black holes yet
(via sciencedaily.com) Astronomers have revealed the closest pair of supermassive black holes to Earth ever observed. The two objects also have a much smaller separation than any other previously spotted pair of supermassive black holes and will eventually merge into one giant black hole.
Published One in five galaxies in the early universe could still be hidden behind cosmic dust
(via sciencedaily.com) Original source Astronomers have discovered two previously invisible galaxies billions of light-years away. Their discovery suggests that up to one in five such distant galaxies remain hidden from our telescopes, camouflaged by cosmic dust. The new knowledge changes perceptions of our universe's evolution since the Big Bang.
Published Black hole found hiding in star cluster outside our galaxy
(via sciencedaily.com) Original source Astronomers have discovered a small black hole outside the Milky Way by looking at how it influences the motion of a star in its close vicinity. This is the first time this detection method has been used to reveal the presence of a black hole outside of our galaxy. The method could be key to unveiling hidden black holes in the Milky Way and nearby galaxies, and to help shed light on how these mysterious objects form and evolve.
