Published ALMA finds new molecular signposts in starburst galaxy
(via sciencedaily.com) Original source The ALMA radio telescope has detected more than 100 molecular species, including many indicative of different star formation and evolution processes, in a galaxy where stars are forming much more actively than in the Milky Way. This is far more molecules than were found in previous studies. Now the team will try to apply this knowledge to other galaxies.
Published Understanding cattle grazing personalities may foster sustainable rangelands
(via sciencedaily.com) Original source New research finds that not all cattle are the same when it comes to grazing, and knowing that could lead to better animal health and range conditions.
Published Astronomers conduct first search for forming planets with new space telescope
(via sciencedaily.com) Original source Planets form in disks of dust and gas called protoplanetary disks that whirl around a central protostar during its final assembly.
Published North American cities may see a major species turnover by the end of the century
(via sciencedaily.com) Original source Climate change may dramatically affect the animal species observed in North American cities, according to a new study.
Published Persistent hiccups in a far-off galaxy draw astronomers to new black hole behavior
(via sciencedaily.com) Original source Astronomers have found that a previously quiet black hole, which sits at the center of a galaxy about 800 million light years away, has suddenly erupted, giving off plumes of gas every 8.5 days before settling back to its normal, quiet state.
Published Combination of the climate crisis and continued deforestation may result in significant damage to the animal world
(via sciencedaily.com) Original source A new study states that the combination of global warming and extreme heat events, alongside the continued expansion of deforestation in the world, may be devastating for many species of animals, especially those that know how to climb trees. As part of the study, the researchers focused on lizards and showed that following the effects of climate change, they will seek refuge from the hot ground by spending a lot of time on trees. However, due to human-related activities, such as deforestation, urbanization and the expansion of agricultural lands at the expense of natural lands, the availability of trees in the areas where the lizards live will decrease, and this may lead to the collapse of many populations.
Published Astronomers unveil strong magnetic fields spiraling at the edge of Milky Way's central black hole
(via sciencedaily.com) Original source A new image from the Event Horizon Telescope (EHT) collaboration has uncovered strong and organized magnetic fields spiraling from the edge of the supermassive black hole Sagittarius A* (Sgr A*). Seen in polarized light for the first time, this new view of the monster lurking at the heart of the Milky Way Galaxy has revealed a magnetic field structure strikingly similar to that of the black hole at the center of the M87 galaxy, suggesting that strong magnetic fields may be common to all black holes.
Published Biologists uncover new species of tiger beetle: Eunota houstoniana
(via sciencedaily.com) Original source Evolutionary biologists have unearthed a new species of tiger beetle, deemed Eunota houstoniana, honoring the Houston region where it predominantly resides.
Published 'Cosmic cannibals' expel jets into space at 40 percent the speed of light
(via sciencedaily.com) Original source Astronomers have measured the speed of fast-moving jets in space, crucial to star formation and the distribution of elements needed for life. The jets of matter, expelled by stars deemed 'cosmic cannibals', were measured to travel at over one-third of the speed of light -- thanks to a groundbreaking new experiment.
Published Sleeping supermassive black holes awakened briefly by shredded stars
(via sciencedaily.com) Original source Astronomers have concluded that an obscure class of galaxies known as Compact Symmetric Objects, or CSOs, are not young as previously thought but rather lead relatively short lives.
Published Researchers find energy development and tree encroachment impact Wyoming pronghorn
(via sciencedaily.com) Original source While Wyoming is home to some of North America's most abundant populations of pronghorn that have largely been stable in recent years, a new analysis shows that many herds are experiencing long-term declines in fawn production.
Published In paleontology, correct names are keys to accurate study
(via sciencedaily.com) Original source When the skeletal remains of a giant ground sloth were first unearthed in 1796, the discovery marked one of the earliest paleontological finds in American history.
Published Tiniest 'starquake' ever detected
(via sciencedaily.com) Original source An orange dwarf star has yielded the tiniest 'starquakes' ever recorded, measured by an international team of scientists.
Published New roadmap to prevent pandemics centers on protecting biodiversity
(via sciencedaily.com) Original source An international team of 25 scientists has proposed a roadmap for how to prevent the next pandemic by conserving natural areas and promoting biodiversity, thereby providing animals with enough food, safe havens and distance to limit contact and the transfer of pathogens to humans.
Published Two coral snakes recorded battling for prey in a scientific first
(via sciencedaily.com) Original source Two red-tailed coral snakes have been observed competing over a caecilian in the first documented wild case of kleptoparasitism within the family Elapidae.
Published Citizen scientists contribute vital information about 35 seahorse species
(via sciencedaily.com) Original source Thanks to diligent observers, seahorses, those enigmatic and charismatic fish, are not only being discovered in new habitats and expanded geographic ranges, they are also being found at new ocean depths. While their capacity for male pregnancy has long fascinated people, new information on sex ratio and pregnancy seasonality has been discovered.
Published Humans pass more viruses to other animals than we catch from them
(via sciencedaily.com) Original source Humans pass on more viruses to domestic and wild animals than we catch from them, according to a major new analysis of viral genomes.
Published Astronomers discover 49 new galaxies in under three hours
(via sciencedaily.com) Original source New work aimed to study the star-forming gas in a single radio galaxy. Although the team didn't find any star-forming gas in the galaxy they were studying, they instead discovered other galaxies while inspecting the data. In total, the gas of 49 galaxies was detected.
Published Wild bird gestures 'after you'
(via sciencedaily.com) Original source A small-bird species, the Japanese tit (Parus minor), uses wing movements as a gesture to convey the message 'after you,' according to new research. When a mating pair arrives at their nest box with food, they will wait outside on perches. One will then often flutter its wings toward the other, apparently indicating for the latter to enter first. The researchers say that this discovery challenges the previous belief that gestural communication is prominent only in humans and great apes, significantly advancing our understanding of visual communication in birds.
Published Research uncovers a rare resin fossil find: A spider that aspires to be an ant
(via sciencedaily.com) Original source Spiders that disguise themselves as ants live in many locations around the globe but until now most had been able to avoid detection from fossil researchers as well as predators.
