Exploding stars      (via sciencedaily.com)     Original source 

When massive stars or other stellar objects explode in the Earth's cosmic neighborhood, ejected debris can also reach our solar system. Traces of such events are found on Earth or the Moon and can be detected using accelerator mass spectrometry, or AMS for short.

'Jurassic worlds' might be easier to spot than modern Earth      (via sciencedaily.com)     Original source 

An analysis finds telescopes could better detect potential chemical signatures of life in an Earth-like exoplanet that more closely resembles the age the dinosaurs inhabited than the one we know today.

Shifting nesting timing not enough to prevent fewer sea turtle hatchlings      (via sciencedaily.com)     Original source 

New research shows that potential adaptive responses by sea turtles, such as shifting the timing of when they nest, may not be enough to counteract the projected impacts from climate change on hatchling production.

How sunflowers see the sun      (via sciencedaily.com)     Original source 

Sunflowers famously turn their faces to follow the sun as it crosses the sky. But how do sunflowers 'see' the sun to follow it? Plant biologists show that they use a different, novel mechanism from that previously thought.

Advanced assisted reproduction in white rhinos is safe and reliable, shows evaluation of procedures      (via sciencedaily.com)     Original source 

The BioRescue project develops and pioneers advanced assisted reproduction technologies (aART) for conservation in the face of the imminent extinction of most rhino species and subspecies. In a new scientific analysis, the team evaluated 65 aART procedures conducted from 2015 to 2022. The evaluation showed that aART is safe for the donor females with no detrimental health effects, and successful in that it yielded 51 embryos.

New map of 20th century land use in Britain helps researchers demystify biodiversity change      (via sciencedaily.com)     Original source 

Researchers have mapped how land use changed across Britain throughout the last century. The new map reveals how and where some 50 per cent of semi-natural grassland was lost, including 90 per cent of the country's lowland meadows and pasture, as the nation intensified its agriculture.

The Crab Nebula seen in new light by NASA's Webb      (via sciencedaily.com)     Original source 

NASA's James Webb Space Telescope has gazed at the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus. Since the recording of this energetic event in 1054 CE by 11th-century astronomers, the Crab Nebula has continued to draw attention and additional study as scientists seek to understand the conditions, behavior, and after-effects of supernovae through thorough study of the Crab, a relatively nearby example.

The importance of the Earth's atmosphere in creating the large storms that affect satellite communications      (via sciencedaily.com)     Original source 

Large geomagnetic storms disrupt radio signals and GPS. Now, researchers have identified the previous underestimated role of the ionosphere, a region of Earth's upper atmosphere that contains a high concentration of ions and free electrons, in determining how such storms develop. Understanding the interactions that cause large geomagnetic storms is important because they can disrupt radio signals and GPS. Their findings may help predict storms with the greatest potential consequences.

Scientists discover molten layer covering Martian core      (via sciencedaily.com)     Original source 

NASA's InSight mission to Mars helped scientists map out Mars' internal structure, including the size and composition of its core, and provided general hints about its tumultuous formation. But findings from a new paper could lead to reanalysis of that data. An international team of researchers discovered the presence of a molten silicate layer overlying Mars' metallic core -- providing new insights into how Mars formed, evolved and became the barren planet it is today.
