Astronomers measure heaviest black hole pair ever found      (via sciencedaily.com)     Original source 

Using archival data from the Gemini North telescope, a team of astronomers has measured the heaviest pair of supermassive black holes ever found. The merging of two supermassive black holes is a phenomenon that has long been predicted, though never observed. This massive pair gives clues as to why such an event seems so unlikely in the Universe.

Microbial viruses act as secret drivers of climate change      (via sciencedaily.com)     Original source 

Scientists have discovered that viruses that infect microbes contribute to climate change by playing a key role in cycling methane, a potent greenhouse gas, through the environment.

Could fiber optic cable help scientists probe the deep layers of the moon?      (via sciencedaily.com)     Original source 

An increasing number of seismologists are using fiber optic cables to detect seismic waves on Earth -- but how would this technology fare on the Moon, and what would it tell us about the deep layers of our nearest neighbor in space?

Astronomers reveal a new link between water and planet formation      (via sciencedaily.com)     Original source 

Researchers have found water vapor in the disc around a young star exactly where planets may be forming. Water is a key ingredient for life on Earth, and is also thought to play a significant role in planet formation. Yet, until now, we had never been able to map how water is distributed in a stable, cool disc -- the type of disc that offers the most favorable conditions for planets to form around stars.

Uncertainty in measuring biodiversity change could hinder progress towards global targets for nature      (via sciencedaily.com)     Original source 

More than ever before, there is a growing interest in dedicating resources to stop the loss of biodiversity, as recently exemplified by the Kunming-Montreal Global Biodiversity Framework (GBF) decided at COP15 in December 2022. The GBF focuses on understanding why biodiversity is declining and what actions are needed to reverse this trend. However, according to researchers, implementing the plan is challenging because information about biodiversity changes is not evenly available everywhere, and is uncertain in many places.

Astronomers discover heavy elements after bright gamma-ray burst from neutron star merger      (via sciencedaily.com)     Original source 

An international team of astronomers obtained observational evidence for the creation of rare heavy elements in the aftermath of a cataclysmic explosion triggered by the merger of two neutron stars.

Genetic research revealed several new fern species in tropical America      (via sciencedaily.com)     Original source 

Researchers have clarified the evolutionary history of a previously poorly known group of ferns from the tropical rainforests of America using DNA methods. The study discovered many new fern species, 18 of which have now been given official names and species descriptions.

A new plant's name that tells a story      (via sciencedaily.com)     Original source 

A new species and genus of fairy lantern, tiny glass-like white plants that feed on fungi, has been discovered in Japan. In the country renowned for its extensive flora research, the discovery of a new plant genus is extremely rare and has not occurred in almost 100 years.

Bottlenecks and beehives: How an invasive bee colony defied genetic expectations      (via sciencedaily.com)     Original source 

An invasive Asian honeybee colony in northern Australia has defied expectations, displaying emergent genetic variation in a short period of time. While bad news for biosecurity agencies, it could be a sign that species under pressure from climate change can be resilient.

The veil varies more than the threat: Predator selection on variability in camouflage and warning signals      (via sciencedaily.com)     Original source 

Researchers leveraged open-access digital collections to validate an age-old hypothesis in evolutionary ecology. The classic hypothesis proposes that predators select for a great variety of camouflage and a limited variety of warning signals, but the idea has never been tested on natural prey.

African great apes predicted to see frequent extreme climate events in the next 30 years      (via sciencedaily.com)     Original source 

African apes are already being exposed to climate change impacts, and will experience extreme events such as wildfires, heatwaves and flooding more frequently in the next 30 years, according to a new study.

Climate change shrinking fish      (via sciencedaily.com)     Original source 

Fish weight in the western North Pacific Ocean dipped in the 2010s due to warmer water limiting food supplies, according to a new study. Researchers analyzed the individual weight and overall biomass of 13 species of fish. In the 1980s and 2010s, the fish were lighter. They attributed the first period of weight loss to greater numbers of Japanese sardine, which increased competition with other species for food. During the 2010s, while the number of Japanese sardine and chub mackerel moderately increased, the effect of climate change warming the ocean appears to have resulted in more competition for food, as cooler, nutrient-dense water could not easily rise to the surface. These results have implications for fisheries and policymakers trying to manage ocean resources under future climate change scenarios.

Counting rays: Aerial surveys reveal ample populations in Southeast Florida      (via sciencedaily.com)     Original source 

A unique long-term study quantified the abundance of whitespotted eagle and giant manta rays in Southeast Florida. Researchers conducted 120 survey flights between 2014 and 2021 from Miami north to the Jupiter Inlet. One or both species were seen on nearly every flight and both populations appear to be stable in the region. The giant manta rays were more abundant in the south and the whitespotted eagle rays were found all along the coast. Neither species seems to be deterred by the greater human population density in Fort Lauderdale/Miami.

Temperature, humidity may drive future transmission of parasitic worm infections      (via sciencedaily.com)     Original source 

Studies on climate and infectious disease typically focus on temperature's role on disease transmission. However, an international team found that both temperature and humidity contribute to future trends in the transmission of parasitic worm infections.
