Published Artificial intelligence enhances monitoring of threatened marbled murrelet
(via sciencedaily.com) Original source Artificial intelligence analysis of data gathered by acoustic recording devices is a promising new tool for monitoring the marbled murrelet and other secretive, hard-to-study species.
Published Feathers, cognition and global consumerism in colonial Amazonia
(via sciencedaily.com) Original source Amazonia is the home of the largest variety of birds in the world. In such a unique environment, craft cultures have flourished by translating the beauty and creativity of environmental materials like feathers into stunning pieces of art. A new article examines artisanal featherwork within the context of early modern colonialism and globalization.
Published Missing link in species conservation: Pharmacists, chemists could turn tide on plant, animal extinction
(via sciencedaily.com) Original source As the world faces the loss of a staggering number of species of animals and plants to endangerment and extinction, one scientist has an urgent message: Chemists and pharmacists should be key players in species conservation efforts.
Published Researchers develop an AI model to reduce uncertainty in evapotranspiration prediction
(via sciencedaily.com) Original source Evapotranspiration (ET) includes evaporation from soil and open water pools such as lakes, rivers, and ponds, as well as transpiration from plant leaves. The difference between precipitation and ET indicates the water balance available for societal needs, including agricultural and industrial production. However, measuring ET is challenging. A new study presents a computer model that uses artificial intelligence (AI) for ET prediction based on remote sensing estimates.
Published Scientists solve chemical mystery at the interface of biology and technology
(via sciencedaily.com) Original source Organic electrochemical transistors (OECTs) allow current to flow in devices like implantable biosensors. But scientists long knew about a quirk of OECTs that no one could explain: When an OECT is switched on, there is a lag before current reaches the desired operational level. When switched off, there is no lag. Current drops immediately. Researchers report that they have discovered the reason for this activation lag, and in the process are paving the way to custom-tailored OECTs for a growing list of applications in biosensing, brain-inspired computation and beyond.
Published Methane emissions from landfill could be turned into sustainable jet fuel in plasma chemistry leap
(via sciencedaily.com) Original source Researchers have developed a chemical process using plasma that could create sustainable jet fuel from methane gas emitted from landfills, potentially creating a low-carbon aviation industry.
Published Biodegradable 'living plastic' houses bacterial spores that help it break down
(via sciencedaily.com) Original source A new type of bioplastic could help reduce the plastic industry's environmental footprint. Researchers have developed a biodegradable form of thermoplastic polyurethane (TPU) filled with bacterial spores that, when exposed to nutrients present in compost, germinate and break down the material at the end of its life cycle.
Published Researchers parse oddity of distantly related bats in Solomon Islands that appear identical
(via sciencedaily.com) Original source A study of body size in leaf-nosed bats of the Solomon Islands has revealed surprising genetic diversity among nearly indistinguishable species on different islands.
Published A virus could help save billions of gallons of wastewater produced by fracking
(via sciencedaily.com) Original source An estimated 168 billion gallons of wastewater -- or produced water -- is generated annually by the Permian Basin fracking industry, according to a 2022 report. The major waste stream has proved both difficult and costly to treat because of the chemical complexity of the water.
Published Discovery of mechanism plants use to change seed oil could impact industrial, food oils
(via sciencedaily.com) Original source Researchers have discovered a new mechanism of oil biosynthesis and found a way to genetically engineer a type of test plant to more efficiently produce different kinds of seed oil that it otherwise wouldn't make. While the engineering is proof-of-concept, this discovery could lead to improved production of valuable oils used in food and by a range of industries. The modified plant overcame metabolic bottlenecks and produced significant amounts of an oil similar to castor oil that it doesn't naturally produce.
Published Trotting robots reveal emergence of animal gait transitions
(via sciencedaily.com) Original source A four-legged robot trained with machine learning has learned to avoid falls by spontaneously switching between walking, trotting, and pronking -- a milestone for roboticists as well as biologists interested in animal locomotion.
Published Fading lights: Multiple threats to North America's firefly populations
(via sciencedaily.com) Original source Scientists have applied a data-driven approach to understanding firefly population dynamics on a continental scale. Key findings from this new study indicate that fireflies, part of the beetle order, are sensitive to various environmental factors, from short-term weather conditions to longer climatic trends, including the number of growing-degree days related to temperature accumulations.
Published Long snouts protect foxes when diving headfirst in snow
(via sciencedaily.com) Original source When hunting for mice in winter, red and arctic fox are known to plunge headfirst at speeds of 2-4 meters per second, but their sharp noses reduce the impact force in snow and protect them from injury, according to a new study.
Published Laser imaging could offer early detection for at-risk artwork
(via sciencedaily.com) Original source A bright yellow pigment favored a century ago by Impressionists such as Matisse and Van Gogh is losing its luster. Researchers have developed a laser imaging technique that can detect the first tiny signs of the pigment's breakdown before they're visible to the eye. The work could help art conservators take earlier steps to make the color last.
Published When does a conductor not conduct?
(via sciencedaily.com) Original source A new study uncovers a switchable, atomically-thin metal-organic material that could be used in future low-energy electronic technologies. The study shows that electron interactions in this material create an unusual electrically-insulating phase in which electrons are 'frozen'. By reducing the population of electrons, the authors are able to unfreeze the remaining electrons, allowing for controlled transitions between insulating and electrically-conductive phases: the key to the on-off binary operations of classical computing.
Published Fixin' to be flexitarian: Scrap fish and invasive species can liven up vegetables
(via sciencedaily.com) Original source Greening the way we eat needn't mean going vegetarian. A healthy, more realistic solution is to adopt a flexitarian diet where seafoods add umami to 'boring' vegetables. A gastrophysicist puts mathematical equations to work in calculating the umami potential of everything from seaweed and shrimp paste to mussels and mackerel.
Published Test reveals mice think like babies
(via sciencedaily.com) Original source Are mice clever enough to be strategic? A neuroscientist who studies learning in humans and animals, and who has long worked with mice, wondered why rodents often performed poorly in tests when they knew how to perform well. With a simple experiment, and by acting as 'a little bit of a mouse psychologist,' he and his team figured it out.
Published Florida dolphin found with highly pathogenic avian flu
(via sciencedaily.com) Original source Report details first-ever finding of highly pathogenic avian influenza virus in North American dolphin.
Published Getting dynamic information from static snapshots
(via sciencedaily.com) Original source Researchers have created TopicVelo, a powerful new method of using the static snapshots from scRNA-seq to study how cells and genes change over time. This will help researchers better study how embryos develop, cells differentiate, cancers form, and the immune system reacts.
Published Could fishponds help with Hawaii's food sustainability?
(via sciencedaily.com) Original source Indigenous aquaculture systems in Hawaii, known as loko i'a or fishponds, can increase the amount of fish and fisheries harvested both inside and outside of the pond. Today, aquaculture supplies less than 1% of Hawaii's 70 million pounds of locally available seafood, but revitalization of loko i'a has the potential to significantly increase locally available seafood.
