Published Large new titanosaurian dinosaur from the Pyrenees
(via sciencedaily.com) Researchers have described the new species of titanosaur dinosaur Abditosaurus kuehnei from the remains excavated at the Orcau-1 site, in the southern Pyrenees (Catalonia, Spain). The semiarticulated 70.5-million-year-old skeleton is the most complete specimen of this herbivorous group of dinosaurs discovered so far in Europe.
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 Low volcanic temperature ushered in global cooling and the thriving of dinosaurs
(via sciencedaily.com) Dinosaurs came to flourish during the Jurassic period after a volcanic eruption roughly 201 millions years ago wiped out many marine and land animals, leaving them able to evolve and grow. Now, further details about this eruption and the mass extinction have been revealed. A group of researchers demonstrated how low temperature magma slowly heated sedimentary rocks, causing high sulfur dioxide and low carbon dioxide emissions, a process which cooled the earth.
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 Muscular study provides new information about how the largest dinosaurs moved and evolved
(via sciencedaily.com) New research has revealed how giant 50-ton sauropod dinosaurs, like Diplodocus, evolved from much smaller ancestors, like the wolf-sized Thecodontosaurus.
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 Within a dinosaur’s head: Ankylosaur was sluggish and deaf
(via sciencedaily.com) Scientists took a closer look at the braincase of a dinosaur from Austria. The group examined the fossil with a micro-CT and found surprising new details: it was sluggish and deaf.
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 Earth's first giant
(via sciencedaily.com) The two-meter skull of an enormous new ichthyosaur species, Earth's first known giant creature, reveals how both the extinct marine reptiles and modern whales became giants.
Published New insights into the timeline of mammal evolution
(via sciencedaily.com) A new study has provided the most detailed timeline of mammal evolution to date.
Published Exquisitely preserved embryo found inside fossilized dinosaur egg
(via sciencedaily.com) A 72 to 66-million-year-old embryo found inside a fossilized dinosaur egg sheds new light on the link between the behavior of modern birds and dinosaurs, according to a new study.
Published An ancient relative of Velociraptor is unearthed in Great Britain
(via sciencedaily.com) Original source A new bird-like dinosaur that used brute strength to overcome its prey has been found by palaeontologists combing through fossils found on the Isle of Wight, on the South Coast of Great Britain.
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 Sauropod dinosaurs were restricted to warmer regions of Earth
(via sciencedaily.com) Original source A study investigated the enigma of why sauropod fossils are only found at lower latitudes, while fossils of other main dinosaur types seem ubiquitously present, with many located in the polar regions.
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.
