Published The other side of the story: How evolution impacts the environment
(via sciencedaily.com) Original source Researchers show that an evolutionary change in the length of lizards' legs can have a significant impact on vegetation growth and spider populations on small islands in the Bahamas. This is one of the first times, the researchers say, that such dramatic evolution-to-environment effects have been documented in a natural setting.
Published Supercomputer simulations provide a better picture of the Sun's magnetic field
(via sciencedaily.com) Original source The new findings challenge the conventional understanding of solar dynamics and could improve predictions of solar weather in the future.
Published Forest protection and carbon dioxide stored in biomass
(via sciencedaily.com) Original source A study has found that worldwide protected forests have an additional 9.65 billion metric tons of carbon stored in their above-ground biomass compared to ecologically similar unprotected areas.
Published Forest birds with short, round wings more sensitive to habitat fragmentation
(via sciencedaily.com) Original source Tropical forest birds, which tend to have wings that are short and round relative to their body length and shape, are more sensitive to habitat fragmentation than the long-, slender-winged species common in temperate forests.
Published Study identifies boat strikes as a growing cause of manatee deaths in Belize
(via sciencedaily.com) Original source The endangered Antillean manatee faces a growing threat from boat strikes in Belize, according to a new study that raises concerns about the survival of what had been considered a relatively healthy population. Belize hosts a population of around 1,000 manatees. With the growth of tourism in recent decades, however, Belize has seen a substantial increase in boat traffic, making boat strikes an increasingly important cause of manatee deaths and injuries.
Published Mitigating climate change through restoration of coastal ecosystems
(via sciencedaily.com) Original source Researchers are proposing a novel pathway through which coastal ecosystem restoration can permanently capture carbon dioxide from the atmosphere. Seagrass and mangroves -- known as blue carbon ecosystems -- naturally capture carbon through photosynthesis, which converts carbon dioxide into living tissue.
Published Towering plume of water escaping from Saturn moon
(via sciencedaily.com) Original source Scientists have observed a towering plume of water vapor more than 6,000 miles long -- roughly the distance from the U.S. to Japan -- spewing from the surface of Saturn's moon, Enceladus.
Published One-third of galaxy's most common planets could be in habitable zone
(via sciencedaily.com) Original source A third of the exoplanets orbiting common M dwarf stars have gentle enough orbits to potentially be in the habitable zone capable of hosting liquid water.
Published The search for habitable planets expands
(via sciencedaily.com) Original source Astronomers are suggesting a new way to expand the search for habitable planets that takes into account a zone not previously considered: the space between the star and what's called soot-line in planet-forming disks.
Published Astronomers discover a key planetary system to understand the formation mechanism of the mysterious 'super-Earths'
(via sciencedaily.com) Original source A study presents the detection of a system of two planets slightly larger than Earth orbiting a cold star in a synchronized dance. Named TOI-2096, the system is located 150 light-years from Earth. This system, located 150 light-years from Earth, is one of the best candidates for a detailed study of their atmosphere with the JWST space telescope.
Published New study provides novel insights into the cosmic evolution of amino acids
(via sciencedaily.com) Original source All biological amino acids on Earth appear exclusively in their left-handed form, but the reason underlying this observation is elusive. Recently, scientists uncovered new clues about the cosmic origin of this asymmetry. Based on the optical properties of amino acids found on the Murchison meteorite, they conducted physics-based simulations, revealing that the precursors to the biological amino acids may have determined the amino acid chirality during the early phase of galactic evolution.
Published Global macrogenetic map of marine habitat-forming species
(via sciencedaily.com) Original source Species known as marine habitat-forming species -- gorgonians, corals, algae, seaweeds, marine phanerogams, etc.-- are organisms that help generate and structure the underwater landscapes. These are natural refuges for other species, and provide biomass and complexity to the seabeds. But these key species in marine ecosystems are currently threatened by climate change and other perturbations derived from human activity. Now, a study warns that even in the marine protected areas (MPAs) the genetic diversity of structural species is not protected, although it is essential for the response and adaptation of populations to changes that alter the natural environment.
Published A deep underground lab could hold key to habitability on Mars
(via sciencedaily.com) Original source Tunnels deep underground in North Yorkshire are providing a unique opportunity to study how humans might be able to live and operate on the Moon or on Mars.
Published Prescribed burns encourage foul-smelling invaders
(via sciencedaily.com) Original source Though prescribed burns reduce wildfire threats and even improve habitat for some animals, new research shows these fires also spread stinknet, an aptly named weed currently invading superblooms across the Southwestern U.S.
Published NASA's Hubble hunts for intermediate-sized black hole close to home
(via sciencedaily.com) Original source Astronomers have come up with what they say is some of their best evidence yet for the presence of a rare class of 'intermediate-sized' black hole that may be lurking in the heart of the closest globular star cluster to Earth, located 6,000 light-years away.
Published Corals mark friendly algae for ingestion -- revealing possible conservation target
(via sciencedaily.com) Original source Biologists reveals how coral cells tag friendly algae before ingesting them, initiating a mutually beneficial relationship. This information could guide next-level coral conservation efforts.
Published An X-ray look at the heart of powerful quasars
(via sciencedaily.com) Original source Researchers have observed the X-ray emission of the most luminous quasar seen in the last 9 billion years of cosmic history, known as SMSS J114447.77-430859.3, or J1144 for short. The new perspective sheds light on the inner workings of quasars and how they interact with their environment.
Published Wildfire spread risk increases where trees, shrubs replace grasses
(via sciencedaily.com) Original source A new study found that as woody plants like shrubs and trees replace herbaceous plants like grasses, spot fires can occur farther away from the original fire perimeter.
Published Climate change to push species over abrupt tipping points
(via sciencedaily.com) Original source Climate change is likely to abruptly push species over tipping points as their geographic ranges reach unforeseen temperatures, finds a new study.
Published Study finds carrying pollen heats up bumble bees, raises new climate change questions
(via sciencedaily.com) Original source A new study finds carrying pollen is a workout that significantly increases the body temperature of bumble bees. This new understanding of active bumble bee body temperatures raises questions about how these species will be impacted by a warmer world due to climate change.
