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.

A bright idea for recycling rare-earth phosphors from used fluorescent bulbs      (via sciencedaily.com)     Original source 

Recycling facilities collect glass and mercury from thrown away fluorescent bulbs, but discarded lighting could also supply rare-earth metals for reuse. The 17 metals referred to as rare earths aren't all widely available and aren't easily extracted with existing recycling methods. Now, researchers have found a simpler way to collect slightly magnetic particles that contain rare-earth metals from spent fluorescent bulbs.

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.

Under pressure: New tool for precise measurement of superconductors      (via sciencedaily.com)     Original source 

Researchers think they have a foundational tool for the thorny problem of how to measure and image the behavior of hydride superconductors at high pressure. They report creatively integrating quantum sensors into a diamond anvil cell, enabling direct readouts of the pressurized material's electrical and magnetic properties.

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.

Diamonds are a chip's best friend      (via sciencedaily.com)     Original source 

New technologies aim to produce high-purity synthetic crystals that become excellent semiconductors when doped with impurities as electron donors or acceptors of other elements. Researchers have now determined the magnitude of the spin-orbit interaction in acceptor-bound excitons in a semiconductor. They broke through the energy resolution limit of conventional luminescence measurements by directly observing the fine structure of bound excitons in boron-doped blue diamond, using optical absorption.

AI-driven lab speeds catalysis research      (via sciencedaily.com)     Original source 

Researchers have developed a 'self-driving' lab that uses artificial intelligence (AI) and automated systems to provide in-depth analyses of catalytic reactions used in chemical research and manufacturing. The new tool, called Fast-Cat, can provide more information in five days than is possible in six months of conventional testing.
