Published Raindrops grow with turbulence in clouds
(via sciencedaily.com) Original source Tackling a long-time mystery, scientists have found that the turbulent movements of air in clouds play a key role in the growth of water droplets and the initiation of rain. The research can improve computer model simulations of weather and climate and ultimately lead to better forecasts.
Published How evolution tamed a deadly virus and why we should still worry
(via sciencedaily.com) Original source Over the last century, a once-deadly mosquito-borne virus has evolved so that it no longer sickens humans. New research shows that changes in the virus's ability to target human cells paralleled the decline in illness and death. The findings offer important lessons in virology that may help guide better preparedness for future outbreaks of other viral diseases.
Published Hens blush when they are scared or excited, study finds
(via sciencedaily.com) Original source Hens fluff their head feathers and blush to express different emotions and levels of excitement, according to a new study.
Published How Saharan dust regulates hurricane rainfall
(via sciencedaily.com) Original source New research underscores the close relationship between dust plumes transported from the Sahara Desert in Africa, and rainfall from tropical cyclones along the U.S. Gulf Coast and Florida.
Published Proof-of-concept study to find functional cure for HIV
(via sciencedaily.com) Original source Researchers conducted a breakthrough proof-of-concept study that found an HIV-like virus particle that could cease the need for lifelong medications.
Published See less to move better: Dynamic schooling of fish by visual selection and focus
(via sciencedaily.com) Original source Sometimes less is more. Researchers accurately modeled dynamic fish schooling by incorporating the tendency of fish to focus on a single visual target instead of the whole school, as well as other visual cues.
Published Researchers record images and data of a shark experiencing a boat strike
(via sciencedaily.com) Original source Researchers have captured what they believe is the first ever video of a shark or any large marine animal being struck by a boat.
Published Researchers enhance tool to better predict where and when wildfires will occur
(via sciencedaily.com) Original source A newly enhanced database is expected to help wildfire managers and scientists better predict where and when wildfires may occur by incorporating hundreds of additional factors that impact the ignition and spread of fire.
Published Scientists use AI to predict a wildfire's next move
(via sciencedaily.com) Original source Researchers have developed a new model that combines generative AI and satellite data to accurately forecast wildfire spread.
Published Fish adjust reproduction in response to predators
(via sciencedaily.com) Original source Some species of fish can evolve their egg-laying habits in response to predators in the area in order to survive, according to new research.
Published New dawn for space storm alerts could help shield Earth's tech
(via sciencedaily.com) Original source Space storms could soon be forecasted with greater accuracy than ever before thanks to a big leap forward in our understanding of exactly when a violent solar eruption may hit Earth. Scientists say it is now possible to predict the precise speed a coronal mass ejection (CME) is travelling at and when it will smash into our planet -- even before it has fully erupted from the Sun.
Published Morals are key to consumer views on lab-grown meat, study finds
(via sciencedaily.com) Original source People's moral values could limit their uptake of lab-grown meat, a study suggests. People who say living a natural life is morally important to them are more likely to reject lab-grown meat -- also known as cultured or cultivated meat -- than those who do not, research shows.
Published The courtship of leopard seals off the coast of South America
(via sciencedaily.com) Original source A pioneering study has unveiled the first paired observations of sexual behavior and vocalizations in wild leopard seals. The study on the mysterious leopard seal represents a major advance in understanding the behavior of one of the most difficult apex predators to study on Earth.
Published Evidence for butchery of giant armadillo-like mammals in Argentina 21,000 years ago
(via sciencedaily.com) Original source Cut marks on fossils could be evidence of humans exploiting large mammals in Argentina more than 20,000 years ago, according to a new study.
Published The most endangered fish are the least studied
(via sciencedaily.com) Original source The most threatened reef fishes are also the most overlooked by scientists and the general public. Scientists measured the level of human interest in 2,408 species of marine reef fish and found that the attention of the scientific community is attracted by the commercial value more than the ecological value of the fishes. The public, on the other hand, is primarily influenced by the aesthetic characteristics of certain species, such as the red lionfish (Pterois volitans) and the mandarinfish (Synchiropus splendidus).
Published Researchers predict fewer, pricier strawberries as temperatures warm
(via sciencedaily.com) Original source Strawberries could be fewer and more expensive because of higher temperatures caused by climate change, according to new research.
Published Logged forests can still have ecological value -- if not pushed too far
(via sciencedaily.com) Original source Researchers have analysed data from 127 studies to reveal 'thresholds' for when logged rainforests lose the ability to sustain themselves. The results could widen the scope of which forests are considered 'worth' conserving, but also show how much logging degrades forests beyond the point of no return.
Published Influenza viruses can use two ways to infect cells
(via sciencedaily.com) Original source Most influenza viruses enter human or animal cells through specific pathways on the cells' surface. Researchers have now discovered that certain human flu viruses and avian flu viruses can also use a second entry pathway, a protein complex of the immune system, to infect cells. This ability helps the viruses infect different species -- and potentially jump between animals and humans.
Published Could intensive farming raise risk of new pandemics?
(via sciencedaily.com) Original source Industrialized farming is often thought to reduce the risk of zoonotic diseases because of better control, biosecurity and separation of livestock. A new study examines the effect of social and economic factors -- which are often overlooked in traditional assessments.
Published Weather experts discover new effect of storm -- in a teacup
(via sciencedaily.com) Original source A new study reveals that Storm Ciaran cut an invisible path of mayhem across southern Britain last autumn, destroying any possibility that 20 million people could have a proper cup of tea at breakfast. The storm's record-breaking low pressure meant the boiling point of water was below the crucial 100 degrees Celsius required for a decent cuppa.
