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.
Published Building bionic jellyfish for ocean exploration
(via sciencedaily.com) Original source Researchers show how biohybrid robots based on jellyfish could be used to gather climate science data from deep in the Earth's oceans.
Published Could fiber optic cable help scientists probe the deep layers of the moon?
(via sciencedaily.com) Original source An increasing number of seismologists are using fiber optic cables to detect seismic waves on Earth -- but how would this technology fare on the Moon, and what would it tell us about the deep layers of our nearest neighbor in space?
Published Astronomers reveal a new link between water and planet formation
(via sciencedaily.com) Original source Researchers have found water vapor in the disc around a young star exactly where planets may be forming. Water is a key ingredient for life on Earth, and is also thought to play a significant role in planet formation. Yet, until now, we had never been able to map how water is distributed in a stable, cool disc -- the type of disc that offers the most favorable conditions for planets to form around stars.
Published Slimming down a colossal fossil whale
(via sciencedaily.com) Original source A 30 million year-old fossil whale may not be the heaviest animal of all time after all, according to a new analysis by paleontologists. The new analysis puts Perucetus colossus back in the same weight range as modern whales and smaller than the largest blue whales ever recorded.
Published Astronomers discover heavy elements after bright gamma-ray burst from neutron star merger
(via sciencedaily.com) Original source An international team of astronomers obtained observational evidence for the creation of rare heavy elements in the aftermath of a cataclysmic explosion triggered by the merger of two neutron stars.
Published 'Cosmic lighthouses' that cleared primordial fog identified with JWST
(via sciencedaily.com) Original source Scientists working with data from NASA's James Webb Space Telescope (JWST) have obtained the first full spectra of some of the earliest starlight in the universe. The images provide the clearest picture yet of very low-mass, newborn galaxies, created less than a billion years after the Big Bang, and suggest the tiny galaxies are central to the cosmic origin story.
Published The West is best to spot UFOs
(via sciencedaily.com) Original source Researchers identified environmental factors that explain why reports of Unidentified Anomalous Phenomena (UAP) are more common in certain regions of the country. Most sightings occur in the American West where proximity to public lands, dark skies and military installations afford more opportunities to see strange objects in the air. Understanding the environmental context of these sightings will make it easier to find explanations for their occurrence and help identify truly anomalous objects that may be a legitimate threat.
Published Radio waves can tune up bacteria to become life-saving medicines
(via sciencedaily.com) Original source Scientists have found a new way to alter the DNA of bacterial cells -- a process used to make many vital medicines including insulin -- much more efficiently than standard industry techniques.
Published Biomolecules from formaldehyde on ancient Mars
(via sciencedaily.com) Original source Organic materials discovered on Mars may have originated from atmospheric formaldehyde, according to new research, marking a step forward in our understanding of the possibility of past life on the Red Planet.
Published Creepy crawlies protect apples when flowers are planted on farms
(via sciencedaily.com) Original source Bugs including hoverflies, lacewings and ladybirds play an important role in keeping Britain's apples healthy, a new study has shown.
