Planets around a black hole?

According to latest theories, planets could be formed even in harsh environments around a black hole, with tens of thousands of Earth-like planets possible within 10 light-years of a massive black hole. This finding opens up new possibilities for astronomy and challenges current understanding of planet formation.

A monkey's balancing act

A study reveals that endangered monkey species in national parks make calculated decisions to balance risks and rewards of sharing space with humans. The research highlights the negative impact of human food consumption on their physical health and the need for sustainable conservation programmes to save declining species.

Reconstructing source of radioactive ruthenium

A study reconstructs the source of radioactive ruthenium detected over Europe in 2017, identifying the southern Ural Mountains in Russia and the Mayak Production Association facility as the likely source. The authors estimated that approximately 250 TBq of radioactivity was released, with most of it occurring on September 26, 2017.

Forests face climate change tug of war

The study reveals that the winner of the climate tug of war between CO2 fertilization and heat stress depends on the ratio between the two. If forests can acclimate, they can tolerate a lower ratio, but if not, it's above 89 parts per million CO2 per degree C of warming. Other factors like forest fires, insect infestation, and exceptio...

New hospital tech disrupts doctors' and nurses' jobs, forces improvisation to ensure patient safety

The introduction of electronic patient records in a Saudi Arabian hospital led to changes in the division of labor between physicians and nursing staff. As a result, staff had to improvise their actions to ensure continued patient safety, often requiring complex renegotiations to re-establish professional boundaries.

Paleoclimate of the Middle East

A study analyzing carbonate minerals in Soreq Cave, Israel, suggests the summer monsoon periodically impacted the region during the last interglacial period. The findings coincide with archaeological evidence of human migration out of Africa, implying paleoclimate may have influenced early human movement.
