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.

A powerful new way to fill major gaps in public bee data -- including from Africa, Asia and other under-reported zones -- has been addressed with a centralized tool for consolidating bee pollinator occurrences around the globe.

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.

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.

Deforestation in the Amazon causes land surfaces up to 100 kilometers away to get warmer, suggests a new study.   The research suggests that tropical forests play a critical role in cooling the land surface -- and that effect can play out over considerable distances.

The first widescale assessment of methylmercury in adult amphibians in the U.S. to date shows that, in amphibians, this toxic compound is common, widespread and, at least for some, can reach very high levels.

The tropical wood type ipe is popular for building exclusive wooden decks, and in North America and Europe, the demand for the material has increased sharply. Now, a study shows that more than three-quarters of all ipe from the top producing region in Brazil could have been harvested illegally.

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.

Scientists analyzed open-source data to track vegetation changes across North America since the end of the Pleistocene Epoch, and conclude that humans have had as much of an impact on the landscape as the retreat of the glaciers at the end of the Ice Age.

Through satellite imaging a new AI driven mapping of biomass and CO2 storage shows that a huge number of trees are overlooked in Europe's urban, rural, and agricultural areas. Across Europe, researchers have discovered a billion tons of hidden biomass.
