Published Groundbreaking survey reveals secrets of planet birth around dozens of stars
(via sciencedaily.com) Original source A team of astronomers has shed new light on the fascinating and complex process of planet formation. The research brings together observations of more than 80 young stars that might have planets forming around them, providing astronomers with a wealth of data and unique insights into how planets arise in different regions of our galaxy.
Published What makes black holes grow and new stars form? Machine learning helps solve the mystery
(via sciencedaily.com) Original source It takes more than a galaxy merger to make a black hole grow and new stars form: machine learning shows cold gas is needed too to initiate rapid growth -- new research finds.
Published Sprinting 'like a jet' will produce Premier League strikers of tomorrow, study shows
(via sciencedaily.com) Original source Sprinting 'like a jet plane taking off' will help produce Premier League star strikers of tomorrow, new research has revealed. A new study of Tottenham Hotspur's academy has shown that just a few words can instantly boost sprinting speed by 3 per cent over 20 meters. It would normally take weeks of targeted training to achieve such a large increase.
Published Juno spacecraft measures oxygen production on Jupiter's moon, Europa
(via sciencedaily.com) Original source NASA's Juno spacecraft has directly measured charged oxygen and hydrogen molecules from the atmosphere of one of Jupiter's largest moons, Europa. These observations provide key constraints on the potential oxygenation of its subsurface ocean.
Published Fossil named 'Attenborough's strange bird' was the first in its kind without teeth
(via sciencedaily.com) Original source A new fossil, named 'Attenborough's strange bird' after naturalist and documentarian Sir David Attenborough, is the first of its kind to evolve a toothless beak. It's from a branch of the bird family tree that went extinct in the mass extinction 66 million years ago, and this strange bird is another puzzle piece that helps explain why some birds -- and their fellow dinosaurs -- went extinct, and others survived to today.
Published Modeling the origins of life: New evidence for an 'RNA World'
(via sciencedaily.com) Original source Scientists provide fresh insights on the origins of life, presenting compelling evidence supporting the 'RNA World' hypothesis. The study unveils an RNA enzyme that can make accurate copies of other functional RNA strands, while also allowing new variants of the molecule to emerge over time. These remarkable capabilities suggest the earliest forms of evolution may have occurred on a molecular scale in RNA, and also bring scientists one step closer to re-creating autonomous RNA-based life in the laboratory.
Published Webb unlocks secrets of one of the most distant galaxies ever seen
(via sciencedaily.com) Original source Looking deeply into space and time, astronomers have studied the exceptionally luminous galaxy GN-z11, which existed when our 13.8 billion-year-old universe was only about 430 million years old.
Published The crow's best friend: Humans
(via sciencedaily.com) Original source A new study has found that when humans are suddenly absent from the urban environment, the activity of the crows and ringneck parakeets that 'live' in the area reduces significantly. Conversely, the graceful prinias, who are generally considered shy, increased their activity.
Published New dressing robot can 'mimic' the actions of care-workers
(via sciencedaily.com) Original source Scientists have developed a new robot that can 'mimic' the two-handed movements of care-workers as they dress an individual.
Published Study determines the original orientations of rocks drilled on Mars
(via sciencedaily.com) Original source Geologists determined the original orientation of many of the Mars bedrock samples collected by the Perseverance rover. The findings can give scientists clues to the conditions in which the rocks originally formed.
Published Beyond the ink: Painting with physics
(via sciencedaily.com) Original source Falling from the tip of a brush suspended in mid-air, an ink droplet touches a painted surface and blossoms into a masterpiece of ever-changing beauty. It weaves a tapestry of intricate, evolving patterns. Some of them resemble branching snowflakes, thunderbolts or neurons, whispering the unique expression of the artist's vision.
Published Orcas demonstrating they no longer need to hunt in packs to take down the great white shark
(via sciencedaily.com) Original source An orca (killer whale) has been observed, for the first-ever time, individually consuming a great white shark -- and within just two minutes.
Published AI outperforms humans in standardized tests of creative potential
(via sciencedaily.com) Original source In a recent study, 151 human participants were pitted against ChatGPT-4 in three tests designed to measure divergent thinking, which is considered to be an indicator of creative thought.
Published New insights on how galaxies are formed
(via sciencedaily.com) Original source Astronomers can use supercomputers to simulate the formation of galaxies from the Big Bang 13.8 billion years ago to the present day. But there are a number of sources of error. An international research team has spent a hundred million computer hours over eight years trying to correct these.
Published Dung beetles show their love by sharing the load
(via sciencedaily.com) Original source Dung beetles share the load when it comes to showing their affection for each-other, when transporting a 'brood ball'.
Published Study identifies multi-organ response to seven days without food
(via sciencedaily.com) Original source New findings reveal that the body undergoes significant, systematic changes across multiple organs during prolonged periods of fasting. The results demonstrate evidence of health benefits beyond weight loss, but also show that any potentially health-altering changes appear to occur only after three days without food.
Published Ultraviolet radiation from massive stars shapes planetary systems
(via sciencedaily.com) Original source Up to a certain point, very luminous stars can have a positive effect on the formation of planets, but from that point on the radiation they emit can cause the material in protoplanetary discs to disperse.
Published Ice shell thickness reveals water temperature on ocean worlds
(via sciencedaily.com) Original source Astrobiologists have devised a novel way to determine ocean temperatures of distant worlds based on the thickness of their ice shells, effectively conducting oceanography from space.
Published Scientists ID burned bodies using technique used for extracting DNA from woolly mammoths, Neanderthals
(via sciencedaily.com) Original source A technique originally devised to extract DNA from woolly mammoths and other ancient archaeological specimens can be used to potentially identify badly burned human remains, according to research.
Published Astronomers measure heaviest black hole pair ever found
(via sciencedaily.com) Original source Using archival data from the Gemini North telescope, a team of astronomers has measured the heaviest pair of supermassive black holes ever found. The merging of two supermassive black holes is a phenomenon that has long been predicted, though never observed. This massive pair gives clues as to why such an event seems so unlikely in the Universe.
