Published Engine wear risk as planes swallow more dust waiting to land
(via sciencedaily.com) Original source Planes flying into one of the world's busiest airports are ingesting around 10kg of dust per 1,000 flights.
Published Study projects major changes in North Atlantic and Arctic marine ecosystems due to climate change
(via sciencedaily.com) Original source New research predicts significant shifts in marine fish communities in the North Atlantic and Arctic Oceans as a result of climate warming.
Published Scientists discover how to improve vaccine responses to potentially deadly bacterium
(via sciencedaily.com) Original source Researchers have taken a leap forward in understanding how we might fight back against the potentially deadly MRSA bacterium. They have shown in an animal model that targeting a key suppressive immune molecule (IL-10) during the delivery of a vaccine improves the ability of the vaccine to protect against infection.
Published Restored oyster sanctuaries host more marine life
(via sciencedaily.com) Original source Oysters sanctuaries in Chesapeake Bay are working for more than just oysters. Compared to nearby harvest areas, sanctuaries contain more abundant populations of oysters and other animal life--and the presence of two common parasites isn't preventing that.
Published Brain size riddle solved as humans exceed evolution trend
(via sciencedaily.com) Original source The largest animals do not have proportionally bigger brains -- with humans bucking this trend -- a new study has revealed.
Published Migrating starlings are no copycats
(via sciencedaily.com) Original source Young, na ve starlings are looking for their wintering grounds independently of experienced conspecifics. Starlings are highly social birds throughout the year, but this does not mean that they copy the migration route from each other. By revisiting a classic 'displacement' experiment and by adding new data, a team of researchers have settled a long-lasting debate.
Published Exploring the radiative effects of precipitation on Arctic amplification and energy budget
(via sciencedaily.com) Original source While, in theory, precipitation impacts the Earth's radiation budget, the radiative effects of precipitation (REP) are poorly understood and excluded from most climate models. Hence, a new study examined the role of REP in the global and regional energy budgets and hydrological cycles, finding that REP significantly contributes to temperature and precipitation variations at different geographical scales, especially in the Arctic warming. This highlights the relevance of including REP in climate modeling for improved accuracy.
Published How dust pollution from shrinking Great Salt Lake affects communities disproportionately
(via sciencedaily.com) Original source Exposure to wind-blown dust from exposed playa of the Utah lake is worse in Hispanic neighborhoods, according to new research. Findings suggest restoring the lake could ease social inequities associated with air pollution.
Published Pasteurization inactivates highly infectious avian flu in milk, study suggests
(via sciencedaily.com) Original source Researchers found no infectious virus in the sampled pasteurized milk products tested for H5N1.
Published Early-onset El Niño means warmer winters in East Asia, and vice versa
(via sciencedaily.com) Original source Researchers have found that the early onset of El Nino around June leads to warm winter climates in Japan, while the late onset of El Nino is associated with colder winters. By analyzing 100-ensemble member climate simulations over the past 61 years, the team found that the warming of the tropical Indian Ocean was a player in warmer Japanese winters.
Published Blue and great tits deploy surprisingly powerful memories to find food
(via sciencedaily.com) Original source Blue and great tits recall what they have eaten in the past, where they found the food and when they found it, a new study shows. In the first experiment of its kind to involve wild animals, blue and great tits demonstrated 'episodic-like' memory to cope with changes in food availability when foraging. The same study may suggest that humans leaving out seeds and nuts for garden birds could be contributing to the evolution of these memory traits.
Published Giant salamander-like creature was a top predator in the ice age before the dinosaurs
(via sciencedaily.com) Original source Meet Gaiasia jennyae, the swamp creature with a toilet seat-shaped head. It lived 40 million years before the first dinosaurs, and it was the top predator in its ecosystem.
Published Study explores what motivates people to watch footage of disasters and extreme weather
(via sciencedaily.com) Original source The release in July 2024 of the blockbuster film Twisters (centred around a social-media celebrity storm-chaser) demonstrates an ongoing public fascination in hazards and extreme weather. The arrival of camera and streaming technologies have made it easier to collect and share such footage in recent years, resulting in often dramatic footage being live-streamed on platforms such as YouTube, TikTok and Discord. Now, a new study has analyzed what might be motivating people to watch these streams -- in some instances for up to 12 hours at a time.
Published Ocean acidification turns fish off coral reefs
(via sciencedaily.com) Original source A new study of coral reefs in Papua New Guinea shows ocean acidification simplifies coral structure, making crucial habitat less appealing to certain fish species.
Published Genetic patterns of world's farmed, domesticated foxes revealed via historical deep-dive
(via sciencedaily.com) Original source Domesticated animals play a prominent role in our society, with two-thirds of American families enjoying the companionship of pets and many others relying on animal products for their nutritional needs. But the process of domestication remains a bit of a mystery.
Published Dampening the 'seeds' of hurricanes
(via sciencedaily.com) Original source Increased atmospheric moisture may alter critical weather patterns over Africa, making it more difficult for the predecessors of many Atlantic hurricanes to form, according to a new study.
Published Researchers identify unique survival strategies adopted by fish in the world's warmest waters
(via sciencedaily.com) Original source A team of researchers have identified unexpected ways coral reef fish living in the warmest waters on earth, in the Arabian Gulf, have adapted to survive extreme temperatures.
Published New model could help provide expectant mothers a clearer path to safe fish consumption
(via sciencedaily.com) Original source Research creates a framework to better balance the nutritional benefit of fish consumption with the risk of mercury exposure to the developing brain.
Published Antarctic ice shelves hold twice as much meltwater as previously thought
(via sciencedaily.com) Original source Slush -- water-soaked snow -- makes up more than half of all meltwater on the Antarctic ice shelves during the height of summer, yet is poorly accounted for in regional climate models. The findings could have profound implications for ice shelf stability and sea level rise.
Published New mathematical model sheds light on the absence of breastfeeding in male mammals
(via sciencedaily.com) Original source Mathematicians ave put forward a hypothesis which suggests that the reason male mammals don't breastfeed might be driven by the rich community of microbes that lives in breast milk and which plays an important part in establishing the gut microbiome of the infant.
