Published Baby star near the black hole in the middle of our Milky Way: It exists after all
(via sciencedaily.com) Scientists have detected the heaviest and youngest infant star ever discovered close to the black hole at the center of our Galaxy. They also identified the region where this 'impossible star' may have formed.
Published Flower power: The role of ants in forest regeneration
(via sciencedaily.com) Ants play a key role in forest regeneration, according to a new article.
Published Liquid nitrogen spray could clean up stubborn moon dust
(via sciencedaily.com) A liquid nitrogen spray can remove almost all of the simulated moon dust from a space suit, potentially solving what is a significant challenge for future moon-landing astronauts.
Published Galactic explosion offers astrophysicists new insight into the cosmos
(via sciencedaily.com) Using data from the James Webb Space Telescope's first year of interstellar observation, an international team of researchers was able to serendipitously view an exploding supernova in a faraway spiral galaxy.
Published Australia's rarest bird of prey disappearing at alarming rate
(via sciencedaily.com) Australia's rarest bird of prey -- the red goshawk -- is facing extinction, with Cape York Peninsula now the only place in Queensland known to support breeding populations.
Published Breathing is going to get tougher
(via sciencedaily.com) Not all pollution comes from people. When global temperatures increase by 4 degrees Celsius, harmful plant emissions and dust will also increase by as much as 14 percent, according to new research.
Published Astronomers discover metal-rich galaxies in early universe
(via sciencedaily.com) While analyzing data from the first images of a well-known early galaxy taken by NASA's James Webb Space Telescope (JWST), astronomers discovered a companion galaxy previously hidden behind the light of the foreground galaxy -- one that surprisingly seems to have already hosted multiple generations of stars despite its young age, estimated at 1.4 billion years old.
Published Certain frogs more sensitive to climate change, not protected
(via sciencedaily.com) Amphibians worldwide are affected by climate change and potentially one of the most threatened. Biologists found that some species of amphibians are more likely to be sensitive to climate change because they are not protected by state or federal regulations. The team determined that approximately 11 percent of anuran species are sensitive to climate change, but are not currently listed as at-risk either at the state, federal, or international levels.
Published The rediscovery of an ethereal fairy lantern brightly illuminates their mysterious past
(via sciencedaily.com) After more than 30 years, botanists have rediscovered Thismia kobensis, a type of mysterious-looking rare plant commonly referred to as 'fairy lanterns'. Thismia kobensis was presumed extinct and the surprise rediscovery of this Japanese variety has illuminated hidden aspects of fairy lanterns that have puzzled and fascinated botanists for centuries.
Published New study reveals biodiversity loss drove ecological collapse after the 'Great Dying'
(via sciencedaily.com) By exploring the stability and collapse of marine ecosystems during the Permian-Triassic mass extinction, researchers gain insights into modern biodiversity crisis.
Published Insect bite marks show first fossil evidence for plants' leaves folding up at night
(via sciencedaily.com) Plants can move in ways that might surprise you. Some of them even show 'sleep movements,' folding or raising their leaves each night before opening them again the next day. Now, researchers offer convincing evidence for these nightly movements, also known as foliar nyctinasty, in fossil plants that lived more than 250 million years ago.
Published Marine heatwaves decimate sea urchins, molluscs and more at Rottnest
(via sciencedaily.com) Researchers believe rising sea temperatures are to blame for the plummeting number of invertebrates such as molluscs and sea urchins at Rottnest Island off Western Australia, with some species having declined by up to 90 per cent between 2007 and 2021.
Published Scientists unlock key to drought-resistant wheat plants with longer roots
(via sciencedaily.com) Growing wheat in drought conditions may be easier in the future. Researchers found the right number of copies of a specific group of genes can stimulate longer root growth, enabling wheat plants to pull water from deeper supplies.
Published Discovery of massive early galaxies defies prior understanding of the universe
(via sciencedaily.com) Six massive galaxies discovered in the early universe are upending what scientists previously understood about the origins of galaxies in the universe.
Published Effort to help pollinators shows successes, limitations
(via sciencedaily.com) A three-year effort to conserve bee populations by introducing pollinator habitat in North Carolina agricultural areas showed some positive effects, as bee abundance and diversity increased in the studied areas. But results of a study examining the program's effectiveness also showed that the quality of the habitat played a key role in these positive effects, and that habitat quality could be impacted by the way the areas are maintained over time.
Published How one of Saturn's moons ejects particles from oceans beneath its surface
(via sciencedaily.com) Enceladus, the sixth largest of Saturn's moons, is known for spraying out tiny icy silica particles -- so many of them that the particles are a key component of the second outermost ring around Saturn. Scientists have not known how that happens or how long the process takes. A study now shows that tidal heating in Enceladus' core creates currents that transport the silica, which is likely released by deep-sea hydrothermal vents, over the course of just a few months.
Published Malaria infection harms wild African apes
(via sciencedaily.com) Scientists conducted a study that reveals the first evidence of harm caused by malaria infection among wild African apes. They discovered that bonobo populations differ in a key immune trait depending on the presence of malaria infection. Infected populations have a higher frequency of an immune variant that protects against developing severe disease, a pattern that mirrors what is observed among human populations.
Published A labyrinth lake provides surprising benefits for an endangered seal
(via sciencedaily.com) The endangered Saimaa ringed seal is an Ice Age relict living in the highly labyrinthine Lake Saimaa, Finland. The newly published work shows that although individual seals have greatly reduced genetic variation, the loss of variation has been complementary, preserving the adaptive potential of the whole population.
Published Urban ponds require attention to ensure biodiversity
(via sciencedaily.com) New research suggests aquatic plants can be utilized as a tool to enhance the co-existence between aquatic invertebrates and their fish predators in urban ponds.
Published Why do Earth's hemispheres look equally bright when viewed from space?
(via sciencedaily.com) When seen from space, Earth's hemispheres -- northern and southern -- appear equally bright. For years, the brightness symmetry between hemispheres remained a mystery. In a new study, researchers reveal a strong correlation between storm intensity, cloudiness and the solar energy reflection rate in each hemisphere. They offer a solution to the mystery, alongside an assessment of how climate change might alter the reflection rate in the future.
