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.

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.

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.

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.

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?

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.

'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.

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.
