Published Cracking the code of hydrogen embrittlement
(via sciencedaily.com) Original source When deciding what material to use for infrastructure projects, metals are often selected for their durability. However, if placed in a hydrogen-rich environment, like water, metals can become brittle and fail. Since the mid-19th century, this phenomenon, known as hydrogen embrittlement, has puzzled researchers with its unpredictable nature. Now, a study brings us a step closer to predicting it with confidence.
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 'Secret' hidden structure paves new way of making more efficient and stable perovskite solar cells
(via sciencedaily.com) Original source Researchers has revealed the existence of surface concavities on individual crystal grains -- which are the fundamental blocks -- of perovskite thin films, and have unraveled their significant effects on the film properties and reliability. Based on this discovery, the team pioneered a new way of making perovskite solar cells more efficient and stable via a chemo-elimination of these grain surface concavities.
Published Solar farms with stormwater controls mitigate runoff, erosion, study finds
(via sciencedaily.com) Original source As the number of major utility-scale ground solar panel installations grows, concerns about their impacts on natural hydrologic processes also have grown. However, a new study by Penn State researchers suggests that excess runoff or increased erosion can be easily mitigated -- if these 'solar farms' are properly built.
Published Hundreds of new genome sequences fill gaps in the fruit fly tree of life
(via sciencedaily.com) Original source A multitude of new genomic sequence data fills major gaps in the fruit fly tree of life, researchers report.
Published Using AI to scrutinize, validate theories on animal evolution
(via sciencedaily.com) Original source By harnessing the power of machine learning, researchers have constructed a framework for analyzing what factors most significantly contribute to a species' genetic diversity.
Published Secrets behind viral precision
(via sciencedaily.com) Original source New research is shedding light on how viruses ensure their survival by precisely timing the release of new viruses. The discovery offers a new theoretical framework for understanding these dynamic biological phenomena.
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 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 Aussie innovation spearheads cheaper seafloor test for offshore wind farms
(via sciencedaily.com) Original source Australian engineers have unveiled a clever new device -- based on a modified speargun -- as a cheap and efficient way to test seabed soil when designing offshore wind farms.
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 Researchers find that frogs can quickly increase their tolerance to pesticides
(via sciencedaily.com) Original source Although there is a large body of research on pests evolving tolerances for the pesticides meant to destroy them, there have been considerably fewer studies on how non-target animals in these ecosystems may do the same.
Published Producing hydrogen and fertilizer at the same time
(via sciencedaily.com) Original source This new concept could allow the needs of previously separate industries to be combined: the production of hydrogen and the production of fertilizer.
Published Study examines urban forests across the United States
(via sciencedaily.com) Original source Tree-planting campaigns have been underway in the United States, especially in cities, as part of climate mitigation efforts given the many environmental benefits of urban forests. But a new study finds that some areas within urban forests in the U.S., may be more capable than trees growing around city home lawns in adapting to a warmer climate.
Published How domestic rabbits become feral in the wild
(via sciencedaily.com) Original source After sequencing the genomes of nearly 300 rabbits from Europe, South America, and Oceania, researchers found that all of them had a mix of feral and domestic DNA. They say this was not what they had expected to find.
Published A stealth fungus has decimated North American bats but scientists may be a step closer to treating white-nose syndrome
(via sciencedaily.com) Original source An invasive fungus that colonizes the skin of hibernating bats with deadly consequences is a stealthy invader that uses multiple strategies to slip into the small mammals' skin cells and quietly manipulate them to aid its own survival. The fungus, which causes the disease white-nose syndrome, has devastated several North American species over the last 18 years.
Published Hatcheries can boost wild salmon numbers but reduce diversity, studies find
(via sciencedaily.com) Original source The ability of salmon hatcheries to increase wild salmon abundance may come at the cost of reduced diversity among wild salmon, according to a new study.
Published Introducing co-cultures: When co-habiting animal species share culture
(via sciencedaily.com) Original source Cooperative hunting, resource sharing, and using the same signals to communicate the same information -- these are all examples of cultural sharing that have been observed between distinct animal species. In a new article, researchers introduce the term 'co-culture' to describe cultural sharing between animal species. These relationships are mutual and go beyond one species watching and mimicking another species' behavior -- in co-cultures, both species influence each other in substantial ways.
