Published Surprising behavior in one of the least studied mammals in the world
(via sciencedaily.com) Original source Beaked whales are among the least studied mammals in the world. Now, a new study reveals surprising information about the Baird's beaked whale species.
Published Spent hemp biomass: A feed use that supports milk production in dairy cows
(via sciencedaily.com) Original source A new study explores whether the plentiful, fibrous byproduct of CBD production holds potential promise as a nutritious, efficiency-boosting feed ingredient for the dairy sector
Published How kelp forests persisted through the large 2014-2016 Pacific marine heatwave
(via sciencedaily.com) Original source New research reveals that denser, and more sheltered, kelp forests can withstand serious stressors amid warming ocean temperatures.
Published Ancient Australian air-breathing fish from 380 million years ago
(via sciencedaily.com) Original source The rivers of Australia, which once flowed across its now dry interior, used to host a range of bizarre animals -- including a sleek predatory lobe-finned fish with large fangs and bony scales. The newly described fossil fish discovered in remote fossil fields west of Alice Springs has been named Harajicadectes zhumini by palaeontologists.
Published How plants obtain nitrogen by supplying iron to symbiotic bacteria
(via sciencedaily.com) Original source Researchers have discovered peptide factors that function in the shoot and root systems to transport iron into the root nodules colonized by nitrogen-fixing bacteria. Moreover, these peptide factors regulate nitrogen homeostasis by maintaining a balance between nitrogen and iron concentrations in plants without rhizobial symbiosis.
Published Two new freshwater fungi species in China enhance biodiversity knowledge
(via sciencedaily.com) Original source Researchers have discovered two new freshwater hyphomycete (mould) species, Acrogenospora alangii and Conioscypha yunnanensis, in southwestern China. The discovery marks the addition of these species to the Acrogenospora and Conioscypha genera, further enriching the diversity of freshwater fungi known in the region.
Published Mystery of moths' warning sound production explained in new study
(via sciencedaily.com) Original source The workings of the ultrasonic warning sounds produced by the wings of a species of moth have been revealed.
Published Scientists 'break the mould' by creating new colors of 'blue cheese'
(via sciencedaily.com) Original source Experts have discovered how to create different colors of blue cheese. After discovering how the classic blue-green veining is created, a team of experts were able to create a variety of different fungal strains that could be used to make cheese with colors ranging from white to yellow-green to red-brown-pink and light and dark blues.
Published Scammed! Animals 'led by the nose' to leave plants alone
(via sciencedaily.com) Original source Fake news works for wallabies and elephants. Herbivores can cause substantial damage to crops or endangered or protected plants, with traditional methods to deter foraging lethal, expensive or ineffective. Biologists are now using aromas from plants naturally repellent with remarkable success to deter the animals.
Published Rare 3D fossils show that some early trees had forms unlike any you've ever seen
(via sciencedaily.com) Original source In the fossil record, trees typically are preserved with only their trunks. They don't usually include any leaves to show what their canopies and overall forms may have looked like. In a new study, researchers describe fossilized trees from New Brunswick, Canada with a surprising and unique three-dimensional crown shape.
Published How leafcutter ants cultivate a fungal garden to degrade plants and provide insights into future biofuels
(via sciencedaily.com) Original source Scientists developed a new method to map exactly how a fungus works with leafcutter ants in a complex microbial community to degrade plant material at the molecular level. The team's insights are important for biofuels development.
Published Zebrafish navigate to find their comfortable temperature
(via sciencedaily.com) Original source Zebrafish are smaller than your little finger, with a brain no more than half the size of a pinhead. Yet these animals possess an efficient navigation system that enables them to find their way back to spots in the water where the temperature suits them.
Published Clown anemonefish seem to be counting bars and laying down the law
(via sciencedaily.com) Original source We often think of fish as carefree swimmers in the ocean, reacting to the world around them without much forethought. However, new research suggests that our marine cousins may be more cognizant than we credit them for. Fish may be counting vertical bars on intruders to determine their threat level, and to inform the social hierarchy governing their sea anemone colonies.
Published Plant receptors that control immunity and development share a common origin
(via sciencedaily.com) Original source Researchers have traced the origin and evolutionary trajectory of plant immune receptors. Their discovery will make it easier to identify immune receptor genes from genomic information and could help in the development of pathogen-resistant crops.
Published Climate change threatens older elephants most, jeopardizing African elephants' future
(via sciencedaily.com) Original source A collaborative team of researchers has conducted first-of-its kind research into how global climate change affects African elephants. The work shows that older elephants will have markedly decreased chances of survival, which will not only drastically reduce the species' overall ability to weather the changing climate but will send ripple effects throughout the surrounding landscape. The team has also modeled possible mitigation scenarios.
Published 'Tiny tornadoes' around leaves spread deadly plant pathogens
(via sciencedaily.com) Original source A new study has analyzed plant spore dispersion at its source, where rain droplets shake flexible leaves to initially disperse pathogens.
Published Discovery of a third RNA virus linage in extreme environments Jan 17, 2024
(via sciencedaily.com) Original source A research group has discovered a novel RNA viral genome from microbes inhabiting a high-temperature acidic hot spring. Their study shows that RNA viruses can live in high-temperature environments (70-80 degrees Celsius), where no RNA viruses have been observed before. In addition to the two known RNA virus kingdoms, a third kingdom may exist.
Published Fungal-rich soil may improve green roofs
(via sciencedaily.com) Original source Green roofs have become increasingly popular thanks to their benefits related to climate adaptation, mitigation, and urban biodiversity management. But, in the U.S., green roofs are typically planted with non-native plants in sterile soils, and their effectiveness declines over time. A new study finds that managing green roof soil microbes boosts healthy urban soil development, which is a methodology that could be applied to support climate resilience in cities.
Published AI-powered app can detect poison ivy
(via sciencedaily.com) Original source To find poison ivy before it finds you, scientists have published a new study in which they show how they used artificial intelligence to confirm that an app can identify poison ivy. The app is not yet commercially available, nor is there a timetable for it to be available.
Published Goats can tell if you are happy or angry by your voice alone
(via sciencedaily.com) Original source Goats can tell the difference between a happy-sounding human voice and an angry-sounding one, according to researchers. A new study reveals that goats may have developed a sensitivity to our vocal cues over their long association with humans.
