Published Loss of nature costs more than previously estimated
(via sciencedaily.com) Original source Researchers propose that governments apply a new method for calculating the benefits that arise from conserving biodiversity and nature for future generations.
Published Microbes impact coral bleaching susceptibility
(via sciencedaily.com) Original source A new study provides insights into the role of microbes and their interaction as drivers of interspecific differences in coral thermal bleaching.
Published Marine algae implants could boost crop yields
(via sciencedaily.com) Original source Scientists have discovered the gene that enables marine algae to make a unique type of chlorophyll. They successfully implanted this gene in a land plant, paving the way for better crop yields on less land.
Published Herbivores, displaced by ocean warming, threaten subtropical seagrass meadows
(via sciencedaily.com) Original source The findings suggest that subtropical seagrasses are less resilient to heavy grazing from marine herbivores, in part because they receive less sunlight relative to their tropical counterparts. As tropical herbivores move into subtropical waters, overgrazing may prevent subtropical seagrass meadows from persisting in these environments.
Published Space tourism? Cosmic radiation exposure
(via sciencedaily.com) Original source Space weather experts are urging regulators and space tourism innovators to work together to protect their passengers and crews from the risks of space weather radiation exposure.
Published Groundbreaking survey reveals secrets of planet birth around dozens of stars
(via sciencedaily.com) Original source A team of astronomers has shed new light on the fascinating and complex process of planet formation. The research brings together observations of more than 80 young stars that might have planets forming around them, providing astronomers with a wealth of data and unique insights into how planets arise in different regions of our galaxy.
Published Juno spacecraft measures oxygen production on Jupiter's moon, Europa
(via sciencedaily.com) Original source NASA's Juno spacecraft has directly measured charged oxygen and hydrogen molecules from the atmosphere of one of Jupiter's largest moons, Europa. These observations provide key constraints on the potential oxygenation of its subsurface ocean.
Published JWST captures the end of planet formation
(via sciencedaily.com) Original source The James Webb Space Telescope is helping scientists uncover how planets form by advancing understanding of their birthplaces and the circumstellar disks surrounding young stars. Scientists have imaged winds from an old planet-forming disk (still very young relative to the Sun) which is actively dispersing its gas content. Knowing when the gas disperses is important as it constrains the time left for nascent planets to consume the gas from their surroundings.
Published Study determines the original orientations of rocks drilled on Mars
(via sciencedaily.com) Original source Geologists determined the original orientation of many of the Mars bedrock samples collected by the Perseverance rover. The findings can give scientists clues to the conditions in which the rocks originally formed.
Published Ultraviolet radiation from massive stars shapes planetary systems
(via sciencedaily.com) Original source Up to a certain point, very luminous stars can have a positive effect on the formation of planets, but from that point on the radiation they emit can cause the material in protoplanetary discs to disperse.
Published Ice shell thickness reveals water temperature on ocean worlds
(via sciencedaily.com) Original source Astrobiologists have devised a novel way to determine ocean temperatures of distant worlds based on the thickness of their ice shells, effectively conducting oceanography from space.
Published 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?
Published Measuring electrical conductivity in microorganisms, approaching understanding of microbial ecosystems
(via sciencedaily.com) Original source Researchers have developed an innovative methodology for measuring the electrical conductivity of microbial communities. This methodology holds promise for the development of batteries and electrochemical sensors using microorganisms and may serve as a pivotal tool in elucidating the role of electricity within microbial ecosystems.
Published Lake ecosystems: Nitrogen has been underestimated
(via sciencedaily.com) Original source An ecological imbalance in a lake can usually be attributed to increased nutrient inputs. The result: increased phytoplankton growth, oxygen deficiency, toxic cyanobacterial blooms and fish kills. Until now, controls in lake management have focused primarily on phosphorus inputs to counteract this effect. Now, this dogma is shaken by a study showing that nitrogen is also a critical driver for phytoplankton growth in lakes worldwide.
Published Study reveals accelerated soil priming under climate warming
(via sciencedaily.com) Original source A new study highlights a crucial biosphere feedback mechanism and its effects on releasing soil carbon into the atmosphere.
Published Study finds drought fuels invasive species after wildfires
(via sciencedaily.com) Original source Scientists uncover the intricate dance between drought, wildfires and invasive species in Southern California's coastal sage scrub ecosystems.
Published Biomolecules from formaldehyde on ancient Mars
(via sciencedaily.com) Original source Organic materials discovered on Mars may have originated from atmospheric formaldehyde, according to new research, marking a step forward in our understanding of the possibility of past life on the Red Planet.
Published Creepy crawlies protect apples when flowers are planted on farms
(via sciencedaily.com) Original source Bugs including hoverflies, lacewings and ladybirds play an important role in keeping Britain's apples healthy, a new study has shown.
Published Extinctions could result as fish change foraging behavior in response to rising temperatures
(via sciencedaily.com) Original source Fish species respond to temperature increases by going after more readily available prey. Models suggest this behavior could lead to more extinctions.
Published Metal scar found on cannibal star
(via sciencedaily.com) Original source When a star like our Sun reaches the end of its life, it can ingest the surrounding planets and asteroids that were born with it. Now, researchers have found a unique signature of this process for the first time -- a scar imprinted on the surface of a white dwarf star.
