Published New coral disease forecasting system
(via sciencedaily.com) Original source Research has led to a new tool for forecasting coral disease that could help conservationists step in at the right times with key interventions. Ecological forecasts are critical tools for conserving and managing marine ecosystems, but few forecasting systems can account for the wide range of ecological complexities in near-real-time.
Published Novel virus identified in zebrafish from the pet trade causes disease in laboratory fish
(via sciencedaily.com) Original source Zebrafish in the pet trade are asymptomatic carriers of previously undescribed microbes, including a novel virus that causes hemorrhaging in infected laboratory fish, researchers report.
Published AI saving humans from the emotional toll of monitoring hate speech
(via sciencedaily.com) Original source A team of researchers have developed a new machine-learning method that detects hate speech on social media platforms with 88 per cent accuracy, saving employees from hundreds of hours of emotionally damaging work.
Published The AI paradox: Building creativity to protect against AI
(via sciencedaily.com) Original source Cultivating creativity in schools is vital for a future driven by artificial intelligence (AI). But while teachers embrace creativity as an essential 21st century skill, a lack of valid and reliable creativity tests means schools struggle to assess student achievement. Now, a new machine-learning model is providing teachers with access to high-quality, fit-for-purpose creativity tests, that can score assessments in a fraction of the time and a fraction of the cost.
Published Bio-inspired cameras and AI help drivers detect pedestrians and obstacles faster
(via sciencedaily.com) Original source Artificial intelligence (AI) combined with a novel bio-inspired camera achieves 100 times faster detection of pedestrians and obstacles than current automotive cameras. This important step for computer vision and AI and can greatly improve the safety of automotive systems and self-driving cars.
Published Researchers improve satellite surveillance of emperor penguins
(via sciencedaily.com) Original source New phenological and behavioral models will help scientists collect more accurate counts of emperor penguins. Emperor penguins are at the top of the food web. They are a reflection of how lower levels of the marine food web are being impacted by climate change. Systematic data collection on the biological component of ecosystems is still in its infancy, especially in harsh environments, in which consistent and repeatable research is particularly hard to achieve.
Published Some species may tolerate climate change better than expected
(via sciencedaily.com) Original source A new model reassesses the proportion of terrestrial and marine species threatened with extinction by climate change. While the forecasts of traditional models estimate that the diversity of terrestrial species in tropical areas could decrease by 54% between now and 2041-2060, this model is more moderate, predicting a decrease of 39%. Nevertheless, this proportion remains alarming and confirms the importance of taking urgent measures to mitigate climate change and its impact on biodiversity.
Published Marine Protected Areas don't line up with core habitats of rare migratory fish, finds new research
(via sciencedaily.com) Original source 62% of Marine Protected Areas (MPAs) designated to protect rare migratory fish species are outside of their core habitats, according to a new modeling study.
Published The secret sex life of coral revealed
(via sciencedaily.com) Original source Corals play an essential role in ocean ecosystems, and like many organisms, they are under threat from climate change and other human activities. To better protect coral, it's first necessary to understand them, in particular their reproductive life cycle, which only happens once a year. For the first time, researchers have produced a model for coral spawning, based on various environmental factors. They achieved this by tapping an often overlooked source of aquatic knowledge, an aquarium.
Published Tracking animals without markers in the wild
(via sciencedaily.com) Original source Researchers developed a computer vision framework for posture estimation and identity tracking which they can use in indoor environments as well as in the wild. They have thus taken an important step towards markerless tracking of animals in the wild using computer vision and machine learning.
Published Global activity of seafloor biodiversity mapped
(via sciencedaily.com) Original source A team of scientists has used artificial intelligence (AI) to map the activities of seafloor invertebrate animals, such as worms, clams and shrimps, across all the oceans of the world.
Published Investigating the origin of circatidal rhythms in freshwater snails
(via sciencedaily.com) Original source While most organisms have biological clocks synchronized with the day-night cycle (circadian rhythms), marine animals in tidal areas have also developed circatidal rhythms to align with the tidal cycle. Comparing the activity and genetic expression of snails from tidal and non-tidal areas, researchers demonstrate that circatidal rhythms develop as snails adapt to tidal environments. These findings highlight the flexibility of biological clocks, enabling organisms to adjust their rhythms according to the environment.
Published AI headphones let wearer listen to a single person in a crowd, by looking at them just once
(via sciencedaily.com) Original source Engineers have developed an artificial intelligence system that lets someone wearing headphones look at a person speaking for three to five seconds to 'enroll' them. The system then plays just the enrolled speaker's voice in real time, even as the pair move around in noisy environments.
Published AI poised to usher in new level of concierge services to the public
(via sciencedaily.com) Original source Concierge services built on artificial intelligence have the potential to improve how hotels and other service businesses interact with customers, a new paper suggests.
Published Biodiversity in crabs: More than counting species
(via sciencedaily.com) Original source Researchers compare the shield shapes of crabs and find unexpected differentiation.
Published Constantly on the hunt for food: Harbor porpoises more vulnerable than previously thought
(via sciencedaily.com) Original source Constantly on the hunt for food: Harbor porpoises more vulnerable than previously thought to the disturbances from humans. The small whales spend more than 60 percent of their day hunting small fish to stay warm in the cold waters. New research shows that harbor porpoises spend little energy on this hunting strategy, but that it makes them vulnerable to human disturbance.
Published Sexual parasitism helped anglerfish invade the deep sea during a time of global warming
(via sciencedaily.com) Original source Members of the vertebrate group including anglerfishes are unique in possessing a characteristic known as sexual parasitism, in which males temporarily attach or permanently fuse with females to mate. Now, researchers show that sexual parasitism arose during a time of major global warming and rapid transition for anglerfishes from the ocean floor to the deep, open sea.
Published Future climate impacts put whale diet at risk
(via sciencedaily.com) Original source A new study predicts future climate change impacts could disrupt the krill-heavy diet that humpback whales in the southern hemisphere consume.
Published New insights into the degradation dynamics of organic material in the seafloor
(via sciencedaily.com) Original source Many processes in the deep sea are not yet well understood, and the role of microbial communities in particular is often a big unknown. This includes, for example, how organic material that sinks from the water surface to the ocean floor is metabolised -- an important building block for a better understanding of the global carbon cycle.
Published 3D printing robot creates extreme shock-absorbing shape, with help of AI
(via sciencedaily.com) Original source See how an autonomous robot created a shock-absorbing shape no human ever could -- and what it means for designing safer helmets, packaging, car bumpers, and more.
