Published Zebra finch chicks don't babble for no reason



Their first vocalizations help young zebra finch males to memorize the songs of adults.
Published Securing competitiveness of energy-intensive industries through relocation: The pulling power of renewables



Countries with limited potential for renewables could save up to 20 percent of costs for green steel and up to 40 percent for green chemicals from green hydrogen if they relocated their energy-intensive production and would import from countries where renewable energy is cheaper.
Published Holographic displays offer a glimpse into an immersive future



Researchers have invented a new optical element that brings us one step closer to mixing the real and virtual worlds in an ordinary pair of eyeglasses using high-definition 3D holographic images.
Published Modeling broader effects of wildfires in Siberia



As wildfires in Siberia become more common, global climate modeling estimates significant impacts on climate, air quality, health, and economies in East Asia and across the northern hemisphere.
Published Researchers show it's possible to teach old magnetic cilia new tricks



Magnetic cilia -- artificial hairs whose movement is powered by embedded magnetic particles -- have been around for a while, and are of interest for applications in soft robotics, transporting objects and mixing liquids. However, existing magnetic cilia move in a fixed way. Researchers have now demonstrated a technique for creating magnetic cilia that can be 'reprogrammed,' changing their magnetic properties at room temperature to change the motion of the cilia as needed.
Published Eruption of mega-magnetic star lights up nearby galaxy



While ESA's satellite INTEGRAL was observing the sky, it spotted a burst of gamma-rays -- high-energy photons -- coming from the nearby galaxy M82. Only a few hours later, ESA's XMM-Newton X-ray space telescope searched for an afterglow from the explosion but found none. An international team realized that the burst must have been an extra-galactic flare from a magnetar, a young neutron star with an exceptionally strong magnetic field.
Published Scientists unveil genetics behind development of gliding



Researchers explain the genomic and developmental basis of the patagium, the thin skin membrane that allows some mammalian species to soar through the air.
Published Bioluminescence first evolved in animals at least 540 million years ago



Bioluminescence first evolved in animals at least 540 million years ago in a group of marine invertebrates called octocorals, according to the results of a new study. The study focuses on an ancient group of marine invertebrates that includes soft corals, pushes back the previous oldest dated example of trait by nearly 300 million years.
Published Squids' birthday influences mating



The day a male spear squid hatches determines which mating tactic he will use throughout his life, according to new research. Spear squid (Heterololigo bleekeri) that hatch earlier in the season become 'consorts' which fight for mating opportunities. Those which hatch later become 'sneakers,' which use more clandestine mating tactics. Researchers found that the mating tactic determined by the birth date was fixed for the squid's whole life. Understanding how mating tactics are influenced by birth date, and the environmental conditions at that time, can help researchers consider how squid might be affected by climate change and the implications for marine resource management.
Published Frog species evolved rapidly in response to road salts



When we think of evolution, we think of a process that happens over hundreds or thousands of years. In research recently published, a species of frog that has evolved over the course of merely 25 years. The adaptation was spurred on by something many assume is innocuous: salt.
Published Wake up and die: Human brain neurons re-entering the cell cycle age quickly shift to senescence



Post-mitotic neurons in the brain that re-enter the cell cycle quickly succumb to senescence, and this re-entry is more common in Alzheimer's disease, according to a new study. The phenomenon may provide an opportunity to learn more about the neurodegeneration process, and the technique used to make this discovery is readily applicable to other inquiries about unique populations of cells in the brain.
Published Warming climate is putting more metals into Colorado's mountain streams



Warming temperatures are causing a steady rise in copper, zinc and sulfate in the waters of Colorado mountain streams affected by acid rock drainage. Concentrations of these metals have roughly doubled in these alpine streams over the past 30 years, presenting a concern for ecosystems, downstream water quality and mining remediation, according to a new study. Natural chemical weathering of bedrock is the source of the rising acidity and metals, but the ultimate driver of the trend is climate change, the report found, and the results point to lower stream volumes and exposure of rock once sealed away by ice as the likely causes.
Published Tropical fish are invading Australian ocean water



A study of shallow-water fish communities on rocky reefs in south-eastern Australia has found climate change is helping tropical fish species invade temperate Australian waters.
Published No bull: How creating less-gassy cows could help fight climate change



A new study has revealed breeding less-flatulent cows and restoring agricultural land could significantly reduce rising methane emission levels, which play a considerable role in climate change.
Published Hey Dave, I've got an idea for you: What's the potential of AI-led workshopping?



Sure, ChatGPT can write a poem about your pet in the style of T.S Eliot, but generative artificial intelligence (AI) chatbots have a potentially more useful role to play in idea generation according to a new study.
Published Fossil frogs share their skincare secrets



Palaeontologists have solved a hundred-year-old mystery of how some fossil frogs preserve their fleshy parts -- it's all down to their skin. Palaeontologists studied 45-million-year-old fossil frogs from the Geiseltal site in central Germany. Remarkably, the fossils show full body outlines of the soft tissues. The team discovered that the excellent condition of the fossil frogs is due to preservation of ancient skin remnants.
Published World's oases threatened by desertification, even as humans expand them



Oases are important habitats and water sources for dryland regions, sustaining 10% of the world's population despite taking up about 1.5% of land area. But in many places, climate change and anthropogenic activities threaten oases' fragile existence. New research shows how the world's oases have grown and shrunk over the past 25 years as water availability patterns changed and desertification encroaches on these wet refuges.
Published To find life in the universe, look to deadly Venus



Despite surface temperatures hot enough to melt lead, lava-spewing volcanoes, and puffy clouds of sulfuric acid, uninhabitable Venus offers vital lessons about the potential for life on other planets, a new paper argues.
Published Everest mountaineer's letters digitized



Letters written by the famous mountaineer George Mallory have been made available to a global audience for the first time, in the centenary year of his fatal attempt to scale Everest.
Published Giant galactic explosion exposes galaxy pollution in action



Astronomers have produced the first high-resolution map of a massive explosion in a nearby galaxy, providing important clues on how the space between galaxies is polluted with chemical elements.
