Published Bees make decisions better and faster than we do, for the things that matter to them
(via sciencedaily.com) Research reveals how millions of years of evolution has engineered honey bees to make fast decisions and reduce risk.
Published Conservation in Indonesia is at risk, a team of researchers who study the region argues
(via sciencedaily.com) Original source Indonesia, home to the largest tropical rainforest in Southeast Asia and over 17,500 islands, is a country packed with biodiversity and endangered species. However, scientists studying the region's species and ecosystems are getting banned from Indonesia, and conservation plans are being blocked. A team of conservation researchers with long-term experience in Indonesia discuss scientific suppression and other research challenges they have witnessed while working in the region. They offer suggestions for how to promote nature conservation, protect data transparency, and share research with the public in this and other regions of the world.
Published Madagascar hippos were forest dwellers
(via sciencedaily.com) Original source Extinct dwarf hippos that once roamed Madagascar lived in forests rather than open grasslands preferred by common hippos on mainland Africa. The findings suggest grasslands that now cover much of the enormous island off the eastern coast of southern Africa were a relatively recent change facilitated by people rather than a natural habitat sustained in part by these famously large vegetarians.
Published Queensland native forestry can help achieve global environment goals
(via sciencedaily.com) Original source Research has revealed that Queensland native forestry, including timber harvesting, could actually help conserve biodiversity and mitigate climate risks.
Published Why there are no kangaroos in Bali (and no tigers in Australia)
(via sciencedaily.com) Original source Researchers are using a new model to clarify why millions of years ago more animal species from Asia made the leap to the Australian continent than vice versa. The climate in which the species evolved played an important role.
Published An easier way to learn quantum processes
(via sciencedaily.com) Original source Scientists show that even a few simple examples are enough for a quantum machine-learning model, the 'quantum neural networks', to learn and predict the behavior of quantum systems, bringing us closer to a new era of quantum computing.
Published World's most threatened seabirds visit remote plastic pollution hotspots
(via sciencedaily.com) Original source Analysis of global tracking data for 77 species of petrel has revealed that a quarter of all plastics potentially encountered in their search for food are in remote international waters -- requiring international collaboration to address.
Published Amazon dolphins at risk from fishing, dams and dredging
(via sciencedaily.com) Original source Amazon river dolphins are under threat from fishing and proposed new dams and dredging, research shows.
Published Estimating the long-term effects of whale shark feeding practices
(via sciencedaily.com) Original source Increasing opportunities for up-close encounters with sharks and other animals are making wildlife tourism one of the fastest growing tourism sectors -- leading ecology experts to venture to one of the world's main sites to investigate the effects of tourism on endangered whale sharks. At Oslob in the Philippines, Flinders University's Southern Shark Ecology Group and Global Ecology Lab joined local Filipino researchers to measure how the daily feeding regimes for resident whale shark population might have affected their behaviour and physiology by assessing their activity and metabolic requirements.
Published Robotic glove that 'feels' lends a 'hand' to relearn playing piano after a stroke
(via sciencedaily.com) Original source A new soft robotic glove is lending a 'hand' and providing hope to piano players who have suffered a disabling stroke or other neurotrauma. Combining flexible tactile sensors, soft actuators and AI, this robotic glove is the first to 'feel' the difference between correct and incorrect versions of the same song and to combine these features into a single hand exoskeleton. Unlike prior exoskeletons, this new technology provides precise force and guidance in recovering the fine finger movements required for piano playing and other complex tasks.
Published European bird communities move to cooler areas, but mountain ranges and coastlines 'control the traffic'
(via sciencedaily.com) Original source A recent study shows that European bird communities have shifted northeastward in the past 30 years. These shifts are faced with obstacles such as mountain ranges and coastlines. Overall, bird communities are moving towards cooler areas but not fast enough to keep up with increasing temperatures.
Published Emulating how krill swim to build a robotic platform for ocean navigation
(via sciencedaily.com) Original source Researchers have presented important first steps in building underwater navigation robots.
Published Humans' ancestors survived the asteroid impact that killed the dinosaurs
(via sciencedaily.com) Original source A Cretaceous origin for placental mammals, the group that includes humans, dogs and bats, has been revealed by in-depth analysis of the fossil record, showing they co-existed with dinosaurs for a short time before the dinosaurs went extinct.
Published Dry days trigger leaves to send a surprising growth signal telling roots to keep growing
(via sciencedaily.com) Original source Scientists have discovered a new molecular signalling pathway, triggered when leaves are exposed to low humidity, that ensures plant roots keep growing towards water. A new study has found that when the leaves of a plant are exposed to dry air (low humidity), they send a shoot-to-root signal, using abscisic acid (ABA), to tell the roots to keep growing. This is a surprising finding as ABA is usually thought to be a growth inhibitor, not a growth promoter.
Published The clue is in the glue -- Nature's secret for holding it together
(via sciencedaily.com) Original source An obscure aquatic plant has helped to explain how plants avoid cracking up under the stresses and strains of growth.
Published Global analysis on pollinators in cities: Wild bees and butterflies are at particular risk
(via sciencedaily.com) Original source Butterflies are being hit hardest by urban growth. Shrinking habitats and food availability are causing their populations to decline. The same applies to many wild bees that fly early in spring. According to a new study, pollination has not yet been impacted by this because honeybees, for example, can compensate for the reduction of urban pollinators. The study is the first comprehensive analysis of the subject and includes data from 133 studies. The results underline the importance of nature conservation measures in urban areas.
Published Conservation policies risk damaging global biodiversity, researchers argue
(via sciencedaily.com) Original source Rewilding, organic farming and the 'nature friendly farming' measures included in some government conservation policies risk worsening the global biodiversity crisis by reducing how much food is produced in a region, driving up food imports and increasing environmental damage overseas.
Published A roadmap for gene regulation in plants
(via sciencedaily.com) Original source For the first time, researchers have developed a genome-scale way to map the regulatory role of transcription factors, proteins that play a key role in gene expression and determining a plant's physiological traits. Their work reveals unprecedented insights into gene regulatory networks and identifies a new library of DNA parts that can be used to optimize plants for bioenergy and agriculture.
Published AI that uses sketches to detect objects within an image could boost tumor detection, and search for rare bird species
(via sciencedaily.com) Original source Teaching machine learning tools to detect specific objects in a specific image and discount others is a 'game-changer' that could lead to advancements in cancer detection, according to researchers.
Published The speed of life: A zoo of cells to study developmental time
(via sciencedaily.com) Original source Researchers have used an unprecedented stem cell zoo to compare six different mammalian species and their developmental time.
