Published How do butterflies stick to branches during metamorphosis?



Most of us learned about butterfly metamorphosis as a kid -- a wriggly caterpillar molts its skin to form a tough chrysalis and emerges as a beautiful butterfly. But how exactly do chrysalises stay anchored as the butterfly brews within? Research shows that, despite their silks being weak and thin on their own, caterpillars can expertly spin them into chrysalis support structures resembling hook-and-loop fasteners and multi-strand safety tethers.
Published 3D laser printing with bioinks from microalgae



Microalgae such as the diatom Odontella aurita and the green alga Tetraselmis striata are especially suitable as 'biofactories' for the production of sustainable materials for 3D laser printing due to their high content in lipids and photoactive pigments. An international research team has succeeded for the first time in manufacturing inks for printing complex biocompatible 3D microstructures from the raw materials extracted from the microalgae.
Published Researchers make breakthrough in understanding species abundance



The key finding was that temperature and genome size, not body size, had the greatest influence on the maximum population growth rate of the diatoms. Yet body size still mattered in colder latitudes, conserving Bermann's Rule.
Published Researchers crack a key celiac mystery



An interdisciplinary team of medical and engineering researchers has spent the last six years working to unlock a significant piece of the puzzle in the search for a cure: how and where the gluten response begins.
Published Researchers outline promises, challenges of understanding AI for biological discovery



Machine learning is a powerful tool in computational biology, enabling the analysis of a wide range of biomedical data such as genomic sequences and biological imaging. But when researchers use machine learning in computational biology, understanding model behavior remains crucial for uncovering the underlying biological mechanisms in health and disease. Researchers now propose guidelines that outline pitfalls and opportunities for using interpretable machine learning methods to tackle computational biology problems.
Published Finding pearls in the mud: Eco-friendly tungsten recovery from semiconductor waste



Semiconductor industry waste is typically seen as a costly disposal problem and an environmental hazard. But what if this waste could be transformed into a valuable resource? In an exciting development, researchers have unveiled an eco-friendly method to extract rare metals from semiconductor waste. This innovative approach not only recovers precious tungsten but also assesses its economic viability, offering a sustainable solution for waste management in the tech industry.
Published 3D bioprinting advances research on respiratory viruses



Researchers develop a microstructured 'artificial lung' model using bioprinting technology.
Published Early mammals lived longer



What distinguishes the growth and development patterns of early mammals of the Jurassic period? Paleontologists have been able to gauge the lifespan and growth rates of these ancient animals, and even when they reached maturity, by studying growth rings in fossilized tooth roots.
Published Effective new catalyst brings hope for cleaner energy, wastewater treatment, and green chemistry



A catalyst that significantly enhances ammonia conversion could improve wastewater treatment, green chemical and hydrogen production.
Published Microscopy technique 'paves way' for improving understanding of cellular functions



Scientists have developed a new way of counting labelled proteins in living cells that could become a standard and valuable tool in the field of biomedical research.
Published Detecting climate change using aerosols



Researchers analyzed long-term aerosol satellite observation big data focusing on the Pacific Ocean downwind of China. Using a newly developed metric that considered aerosols as tracers, they detected altered atmospheric transport patterns associated with climate change. They observed that the distance of transboundary air pollution moving east from China had shortened. Thus, long-term satellite-based Earth observations are crucial for early climate change detection and accurate evaluation of this trend.
Published Children can inherit early aging symptoms from parents who abuse alcohol, researchers find



Researchers say they now know that offspring are inheriting dysfunction in their mitochondria as a result of their parents' substance abuse. This dysfunction causes these individuals to show early signs of age-related disease when they're still considered young, usually in their 40s.
Published Increasing clinicians' knowledge about climate change's impact on health and healthcare sustainability



A novel educational program for clinicians provided a foundation about climate change and the impact of fossil fuel-related pollution on individual health, and how healthcare systems contribute to carbon pollution and can address these challenges.
Published Unlocking the secrets of salt stress tolerance in wild tomatoes



As our climate changes and soil salinity increases in many agricultural areas, finding crops that can thrive in these challenging conditions is crucial. Cultivated tomatoes, while delicious, often struggle in salty soils. Their wild cousins, however, have evolved to survive in diverse and often harsh environments. A recent study delved into the genetic treasure trove of wild tomatoes to uncover secrets of salt tolerance that could be used to develop resilient crop varieties.
Published Studying how serotonin alters locust's sense of smell



Researchers study the role of serotonin in altering odor driven behavioral and neural responses in locusts.
Published Mix of factors prompts owl monkeys to leave their parents



There comes a point in the lives of young owl monkeys when they leave their parents and strike out on their own to find a mate. In a new study of a wild population of Azara's owl monkeys in northern Argentina, researchers reveal that a combination of social and ecological factors influences when these tree-dwelling monkeys peel away from their parents and siblings. According to their findings -- which were based on 25 years of genetic and demographic data for several generations of owl monkeys, covering more than 330 individuals -- none of the individuals, regardless of their sex, reproduced in the same group where they were born. In all cases, the researchers found, the animals either departed from their natal group or died before reproducing.
Published How ribosomes in our cells enable protein folding



Scientists discovered a role played by ribosomes during the folding of new proteins in cells.
Published Alaskan land eroding faster due to climate change



A new study shows that frozen land in Alaska is eroding faster than it can be replaced due to climate change.
Published Viral defense protein speeds up female stem cell production



A viral defense mechanism can be used to accelerate the creation of female stem cell lines in mice. The findings can boost efforts in medical research, drug testing, and regenerative therapies, particularly for women and individuals with two X chromosomes.
Published Individuals vary in how air pollution impacts their mood



Affective sensitivity to air pollution (ASAP) describes the extent to which affect, or mood, fluctuates in accordance with daily changes in air pollution, which can vary between individuals, according to a new study.
