Published A blueprint for building the future: Eco-friendly 3D concrete printing
(via sciencedaily.com) Original source Scientists are improving 3D concrete printing construction technology with rigorous research to make printable materials stronger, more sustainable and better performing.
Published Link between global warming and rising sea levels
(via sciencedaily.com) Original source A new study suggests that Earth's natural forces could substantially reduce Antarctica's impact on rising sea levels, but only if carbon emissions are swiftly reduced in the coming decades. By the same token, if emissions continue on the current trajectory, Antarctic ice loss could lead to more future sea level rise than previously thought.
Published Improving cat food flavors with the help of feline taste-testers
(via sciencedaily.com) Original source Cats are notoriously picky eaters. But what if we could design their foods around flavors that they're scientifically proven to enjoy? Researchers used a panel of feline taste-testers to identify favored flavor compounds in a series of chicken-liver-based sprays. The cats particularly enjoyed the sprays that contained more free amino acids, which gave their kibble more savory and fatty flavors.
Published Discovery of a new population of macrophages promoting lung repair after viral infections
(via sciencedaily.com) Original source Researchers have discovered a new population of macrophages, important innate immune cells that populate the lungs after injury caused by respiratory viruses. These macrophages are instrumental in repairing the pulmonary alveoli. This groundbreaking discovery promises to revolutionize our understanding of the post-infectious immune response and opens the door to new regenerative therapies.
Published New compound effective against flesh-eating bacteria
(via sciencedaily.com) Original source Researchers have developed a compound that is effective against common bacteria that can lead to rare, dangerous illnesses.
Published Allergy cells' hidden secret
(via sciencedaily.com) Original source Known for their role in allergic reactions, mast cells have long been recognised as key players in our immune system. When they encounter allergens, they release chemicals that trigger typical allergy symptoms such as tissue swelling and inflammation. Now, researchers have discovered a hidden talent of mast cells: they can capture and use another type of immune cell called neutrophils. This surprising discovery sheds new light on how our immune system works, particularly during allergic reactions.
Published Reduction in folate intake linked to healthier aging in animal models
(via sciencedaily.com) Original source Scientists found that decreasing folate intake can support healthier metabolisms in aging animal models, challenging the conventional belief that high folate consumption universally benefits health.
Published Coinfecting viruses impede each other's ability to enter cells
(via sciencedaily.com) Original source The process by which phages -- viruses that infect and replicate within bacteria -- enter cells has been studied for over 50 years. In a new study, researchers have used cutting-edge techniques to look at this process at the level of a single cell.
Published New research sheds light on relationships between plants and insects in forest ecosystems
(via sciencedaily.com) Original source Researchers have published new findings on how leaf-eating insects affect forest ecosystems worldwide. Researchers are aware of how large herbivores cycle nutrients in forests. They know much less, however, about how leaf-eating insects impact forest carbon and nutrient cycling.
Published Ancient Antarctic microorganisms are aggressive predators
(via sciencedaily.com) Original source Antarctic dwelling single-celled microorganisms called archaea can behave like parasites, new research shows.
Published Revolutionary loop heat pipe transports 10 kW of waste heat -- No electricity required
(via sciencedaily.com) Original source Researchers have unveiled a new loop heat pipe capable of transporting up to 10 kW of heat without using electric power. The loop heat pipe's design aims to contribute to energy savings and carbon neutrality in various fields, including waste heat recovery, solar heat utilization, electric vehicle thermal management, and data center cooling.
Published Born to modulate: Researchers reveal origins of climate-controlling particles
(via sciencedaily.com) Original source Aerosol particles imbue climate models with uncertainty. New work reveals where in the world and under what conditions new particles are born.
Published Circular RNAs: The new frontier in cancer research
(via sciencedaily.com) Original source Unravelling the complexities of circular RNAs (circRNAs) in cancer biology has positioned scientists on the cusp of revolutionary breakthroughs in the diagnosis and treatment of cancer. A new study predicts remarkable potential for circular RNAs to improve cancer treatment and patient outcomes within the next 5-10 years.
Published Sea level changes shaped early life on Earth, fossil study reveals
(via sciencedaily.com) Original source Shifts in the Earth's continental plates that drove long-term changes in sea level set the stage for the evolution of the earliest animals on Earth, a study suggests.
Published Combined effects of plastic pollution and seawater flooding amplify threats to coastal plant species
(via sciencedaily.com) Original source A new study highlights how a combination of environmental stressors -- namely plastic pollution and seawater flooding -- can increase the threats faced by plants in some of the planet's critical ecosystems. It showed that both stressors had some effects on the species tested, but being exposed to both microplastics and flooding together -- a threat likely to increase as a result of climate change and plastic use -- had a more pronounced impact on their resource allocation.
Published Breakthrough in bid to develop vaccines and drugs for neglected tropical disease
(via sciencedaily.com) Original source A breakthrough lays the foundations for vaccine development and for testing new preventative measures against the neglected tropical disease leishmaniasis.
Published Scientists find a human 'fingerprint' in the upper troposphere's increasing ozone
(via sciencedaily.com) Original source Scientists confirmed that much of ozone's increase in the upper troposphere is likely due to humans. A team detected a clear signal of human influence on upper tropospheric ozone trends in a 17-year satellite record starting in 2005.
Published What gave the first molecules their stability?
(via sciencedaily.com) Original source The origins of life remain a major mystery. How were complex molecules able to form and remain intact for prolonged periods without disintegrating? A team has demonstrated a mechanism that could have enabled the first RNA molecules to stabilize in the primordial soup. When two RNA strands combine, their stability and lifespan increase significantly.
Published Genetic signatures of domestication identified in pigs, chickens
(via sciencedaily.com) Original source Wild boars and red junglefowl gave rise to common pigs and chickens. These animals' genes evolved to express themselves differently, leading to signatures of domestication -- such as weaker bones and better viral resistance -- in pigs and chickens, according to a research team.
Published Healthy AI: Sustainable artificial intelligence for healthcare
(via sciencedaily.com) Original source Researchers investigated the environmental costs of AI, including energy consumption of AI systems in the medical field, carbon emissions of data centers, and electronic waste issues. Specific solutions to mitigate these environmental impacts were discussed, including the development of energy-efficient AI models, the implementation of green computing, and the use of renewable energy.
