A window of opportunity for climate change and biodiversity      (via sciencedaily.com)     Original source 

World leaders must take advantage of a pivotal window of opportunity for forging a much-needed joined-up approach to tackle climate change and biodiversity loss, say scientists. Without this, work on tackling either crisis could inadvertently harm progress on the other.

Hot traces in rock      (via sciencedaily.com)     Original source 

Fluids circulating underground change rocks over the course of time. These processes must be taken into account if they are to be used as a climate archive. Researchers have used 380-million-year-old limestones from Hagen-Hohenlimburg to show in detail which climate information is still preserved in the rock.

Risks and benefits of integrating AI into medical decision-making      (via sciencedaily.com)     Original source 

Researchers found that an artificial intelligence (AI) model solved medical quiz questions -- designed to test health professionals' ability to diagnose patients based on clinical images and a brief text summary -- with high accuracy. However, physician-graders found the AI model made mistakes when describing images and explaining how its decision-making led to the correct answer.

Expiring medications could pose challenge on long space missions      (via sciencedaily.com)     Original source 

A new study shows that over half of the medicines stocked in space -- staples such as pain relievers, antibiotics, allergy medicines, and sleep aids -- would expire before astronauts could return to Earth.

Tropical plant species are as threatened by climate change as widely feared, study confirms      (via sciencedaily.com)     Original source 

Biologists who set out to better understand the effects of climate change on plant species in tropical mountain regions found that even small variations in temperature and moisture can have massive impacts, threatening not only plants that live there, but also the ecosystems they support. A study based on labor-intensive fieldwork and analysis in tropical mountain regions shows that a warmer and drier climate will lead to massive losses of plant species.

Astrophysicists uncover supermassive blackhole/dark matter connection in solving the 'final parsec problem'      (via sciencedaily.com)     Original source 

Researchers have found a link between some of the largest and smallest objects in the cosmos: supermassive black holes and dark matter particles. Their new calculations reveal that pairs of supermassive black holes (SMBHs) can merge into a single larger black hole because of previously overlooked behavior of dark matter particles, proposing a solution to the longstanding 'final parsec problem' in astronomy.
