Published Characterizing abnormal neural networks in dogs with anxiety
(via sciencedaily.com) Researchers report abnormalities in functional neural networks of dogs diagnosed with anxiety. The study shows that compared with healthy dogs, those with anxiety exhibit stronger connections between the amygdala and other regions of the anxiety network. The findings might also help reveal how functional connections between anxiety-related regions of the brain are altered in cases of human anxiety disorders.
Published Remains of a modern glacier found near Mars' equator implies water ice possibly present at low latitudes on Mars even today
(via sciencedaily.com) Scientists revealed the discovery of a relict glacier near Mars' equator. Located in Eastern Noctis Labyrinthus at coordinates 7° 33' S, 93° 14' W, this finding is significant as it implies the presence of surface water ice on Mars in recent times, even near the equator. This discovery raises the possibility that ice may still exist at shallow depths in the area, which could have significant implications for future human exploration.
Published Mild fever helps clear infections faster, new study suggests
(via sciencedaily.com) It may be better to let a mild fever run its course instead of automatically reaching for medication, new research suggests. Researchers found that untreated moderate fever helped fish clear their bodies of infection rapidly, controlled inflammation and repaired damaged tissue. Moderate fever is self-resolving, meaning that the body can both induce it and shut it down naturally without medication. The health advantages of natural fever to humans still have to be confirmed through research, but the researchers say because the mechanisms driving and sustaining fever are shared among animals, it is reasonable to expect similar benefits are going to happen in humans.
Published Where did Earth's water come from? Not melted meteorites, according to scientists
(via sciencedaily.com) A new study brings scientists one step closer to answering the question of where Earth's water came from.
Published Bird flu associated with hundreds of seal deaths in New England in 2022
(via sciencedaily.com) Researchers have found that an outbreak of highly pathogenic avian influenza (HPAI) was associated with the deaths of more than 330 New England harbor and gray seals along the North Atlantic coast in June and July 2022, and the outbreak was connected to a wave of avian influenza in birds in the region.
Published High winds can worsen pathogen spread at outdoor chicken farms
(via sciencedaily.com) A study of chicken farms in the West found that high winds increased the prevalence of Campylobacter in outdoor flocks, a bacterial pathogen in poultry that is the largest single cause of foodborne illness in the U.S. Researchers found that about 26% of individual chickens had the pathogen at the 'open environment' farms in the study, which included organic and free-range chicken farms. High winds the week prior to sampling and the farms' location in more intensive agricultural settings were linked to a greater prevalence of Campylobacter.
Published Climate change alters a human-raptor relationship
(via sciencedaily.com) Bald Eagles and dairy farmers exist in a mutually beneficial relationship in parts of northwestern Washington State. According to a new study, this 'win-win' relationship has been a more recent development, driven by the impact of climate change on eagles' traditional winter diet of salmon carcasses, as well as by increased eagle abundance following decades of conservation efforts.
Published Swan populations grow 30 times faster in nature reserves
(via sciencedaily.com) Populations of whooper swans grow 30 times faster inside nature reserves, new research shows.
Published Entire populations of Antarctic seabirds fail to breed due to extreme, climate-change-related snowstorms
(via sciencedaily.com) The arrival of the new year is a prime time for Antarctic birds like the south polar skua, Antarctic petrel, and snow petrel to build nests and lay their eggs. However, from December 2021 to January 2022, researchers did not find a single skua nest on Svarthamaren, one of the regions where the birds go to raise their young. Similarly, the number of Antarctic petrel and snow petrel nests dropped to almost zero.

Published Looking for risky viruses now to get ahead of future pandemics
(via sciencedaily.com) Rather than let the next outbreak take the world by surprise, two virologists say that the scientific community should invest in a four-part research framework to proactively identify animal viruses that might infect humans.
Published Jewel beetles evolve to see new colors by duplicating their genes
(via sciencedaily.com) Jewel beetles are striking insects, easily recognized by their vivid colors and metallic sheen. New research investigated the complex evolutionary history of jewel beetles' vision.
Published Remarkable squirting mussels captured on film
(via sciencedaily.com) Researchers have observed a highly unusual behavior in the endangered freshwater mussel, Unio crassus. The jets disturb the river surface and attract fish. Mussel larvae in the jets can then attach to the gills of the fish and complete their metamorphosis into adults.
Published Sea temperatures control the distributions of European marine fish
(via sciencedaily.com) An analysis extending from southern Portugal to northern Norway highlights the importance of temperature in determining where fish species are found.
Published Migratory birds take breaks to boost their immune system
(via sciencedaily.com) Exercising too much and not getting enough rest is likely bad for your health. A new study shows that the same is true for migratory birds. They need to rest not only to renew their energy levels but also in order to boost their immune system.
Published Scientists call for global push to eliminate space junk
(via sciencedaily.com) As almost 200 countries agree a legally-binding treaty to protect the High Seas, a collaboration of experts in ocean plastic pollution and satellite technology has urged world leaders to learn lessons from the management of the High Seas and act now to protect Earth's orbit.
Published Island-inhabiting giants, dwarfs more vulnerable to extinction
(via sciencedaily.com) Island-dwelling mammal species often expand or contract in size, becoming giant or dwarf versions of their mainland counterparts. A new Science study from a global team shows that those giants and dwarfs have faced extreme risk of extinction -- an existential threat exacerbated by the arrival of humans.
Published eDNA holds the key to safeguarding pollinators amid global declines
(via sciencedaily.com) Researchers have uncovered new evidence of western pygmy possums interacting with native flowers, providing an eDNA study to simultaneously detect mammal, insect and bird DNA on flowers.
Published ALMA traces history of water in planet formation back to the interstellar medium
(via sciencedaily.com) Observations of water in the disk forming around protostar V883 Ori have unlocked clues about the formation of comets and planetesimals in our own solar system.
Published Grassroots data vital for reducing deadly bird-window strikes
(via sciencedaily.com) Much of the progress made in understanding the scope of bird deaths from building and window collisions has come as the result of citizen science, according to a newly published study. But the study also concludes that such grassroots efforts need more buy-in from government and industry, and better funding so they can keep a foot on the gas in their efforts to reduce bird-window collisions.
