Unlocking neutron star rotation anomalies: Insights from quantum simulation      (via sciencedaily.com)     Original source 

A collaboration between quantum physicists and astrophysicists has achieved a significant breakthrough in understanding neutron star glitches. They were able to numerically simulate this enigmatic cosmic phenomenon with ultracold dipolar atoms. This research establishes a strong link between quantum mechanics and astrophysics and paves the way for quantum simulation of stellar objects from Earth.

10-billion-year, 50,000-light-year journey to black hole      (via sciencedaily.com)     Original source 

A star near the supermassive black hole at the center of the Milky Way Galaxy originated outside of the Galaxy according to a new study. This is the first time a star of extragalactic origin has been found in the vicinity of the super massive black hole.

New theory unites Einstein's gravity with quantum mechanics      (via sciencedaily.com)     Original source 

The prevailing assumption has been that Einstein's theory of gravity must be modified, or 'quantized', in order to fit within quantum theory. This is the approach of two leading candidates for a quantum theory of gravity, string theory and loop quantum gravity. But a new theory challenges that consensus and takes an alternative approach by suggesting that spacetime may be classical -- that is, not governed by quantum theory at all.

Himalayan glaciers react, blow cold winds down their slopes      (via sciencedaily.com)     Original source 

Himalayan Glaciers fight back to preserve themselves, but for how long? An international team of researchers explains a stunning phenomenon: rising global temperatures have led Himalayan glaciers to increasingly cool the air in contact with the ice surface. The ensuing cold winds might help cool the glaciers and preserve the surrounding ecosystems. The results were found across the Himalayan range.

Ghostlike dusty galaxy reappears in James Webb Space Telescope image      (via sciencedaily.com)     Original source 

Astronomers studying images from the James Webb Space Telescope have identified an object as a 'dusty star-forming galaxy' from nearly 1 billion years after the Big Bang. They have also discovered more than a dozen additional candidates, suggesting these galaxies might be three to 10 times as common as expected. If that conclusion is confirmed, it suggests the early universe was much dustier than previously thought.

Meteorites likely source of nitrogen for early Earth      (via sciencedaily.com)     Original source 

Micrometeorites originating from icy celestial bodies in the outer Solar System may be responsible for transporting nitrogen to the near-Earth region in the early days of our solar system.

A new possible explanation for the Hubble tension      (via sciencedaily.com)     Original source 

The universe is expanding. How fast it does so is described by the so-called Hubble-Lemaitre constant. But there is a dispute about how big this constant actually is: Different measurement methods provide contradictory values. This so-called 'Hubble tension' poses a puzzle for cosmologists. Researchers are now proposing a new solution: Using an alternative theory of gravity, the discrepancy in the measured values can be easily explained -- the Hubble tension disappears.

Ash can fertilize the oceans      (via sciencedaily.com)     Original source 

Flames roared through Santa Barbara County in late 2017. UC Santa Barbara canceled classes, and the administration recommended donning an N95, long before the COVID pandemic made the mask a household item. Smoke and ash choked the air, but the Thomas Fire's effects weren't restricted to the land and sky. Huge amounts of ash settled into the oceans, leaving researchers to wonder what effect it might have on marine life.

Study identifies key algae species helping soft corals survive warming oceans      (via sciencedaily.com)     Original source 

During a two-year survey of soft corals in the Florida Keys,  scientists identified three species of octocorals that have survived heat waves. While the coral animal itself may be heat tolerant, scientists concluded that the symbiotic algae inside the coral serve as a protector of sorts.

Illuminating the benefits of marine protected areas for ecotourism, and vice versa      (via sciencedaily.com)     Original source 

As California, the U.S. and the world work to make good on commitments to conserve 30% of oceans and lands by 2030, all strategies are on the table -- and under the microscope. When it comes to the ocean, one valuable tool is marine protected areas (MPAs), regions that are defined, designated and managed for long-term conservation. Among other benefits, MPAs protect habitats and promote species diversity. They also hold value for communities and industries.
