Published Scientists, farmers and managers work together to avoid the decline of the little bustard, an endangered steppe bird
(via sciencedaily.com) Original source The collaboration between scientists, farmers and managers is crucial to improve the protection of the little bustard, an endangered steppe-land bird in Spain due to human activity. The reduction of natural habitats, the increase in irrigation and the urbanization of the land have led to having less surface areas that guarantee the survival of this vulnerable species.
Published Butterflies could lose spots as climate warms
(via sciencedaily.com) Original source Female meadow brown butterflies have fewer spots if they develop in warmer weather -- so climate change could make them less spotty, new research shows.
Published DNA construction led to unexpected discovery of important cell function
(via sciencedaily.com) Original source Researchers have used DNA origami, the art of folding DNA into desired structures, to show how an important cell receptor can be activated in a previously unknown way. The result opens new avenues for understanding how the Notch signalling pathway works and how it is involved in several serious diseases.
Published Why animals shrink over time explained with new evolution theory
(via sciencedaily.com) Original source The new theoretical research proposes that animal size over time depends on two key ecological factors.
Published New technique visualizes mechanical structure of the cell nucleus
(via sciencedaily.com) Original source The cell nucleus is considered to be the control center of vital cellular processes, but its material properties continue to puzzle scientists. An international research team has now developed a new technique that provides a previously unattainable view of the mechanical properties inside this control center. For the first time, it has been possible to visualize over time its peculiar dynamic structural features in living cells, which appear to be crucial for cell function.
Published Key factors in human-made earthquakes
(via sciencedaily.com) Original source Researchers report that the roughness of pre-existing faults and associated stress heterogeneity in geological reservoirs play a key role for causing human-made earthquakes, so-called runaway events. The study combines novel fluid injection experiments under acoustic monitoring performed in GFZ's geomechanical laboratory with numerical modelling results.
Published Translating nuclear waste site data into microbial ecosystem insights
(via sciencedaily.com) Original source A flagship seven-year study that explores how environmental stresses influence different ecological processes shaping the composition and structure of microbial communities in groundwater has now been published.
Published New potato-threatening pathogens reported for first time in Pennsylvania, US
(via sciencedaily.com) Original source As the home of many beloved snack companies, Pennsylvania values its potatoes. Tasty tubers across the state may face the threat of newly identified pathogen strains, though, according to researchers who made the finding and aim to develop management strategies.
Published Ancient 'chewing gum' reveals stone age diet
(via sciencedaily.com) Original source What did people eat on the west coast of Scandinavia 10,000 years ago? A new study of the DNA in a chewing gum shows that deer, trout and hazelnuts were on the diet. It also shows that one of the individuals had severe problems with her teeth.
Published Nearly dead plants brought back to life: Keys to aging hidden in the leaves
(via sciencedaily.com) Original source Scientists have known about a particular organelle in plant cells for over a century. However, scientists have only now discovered that organelle's key role in aging.
Published Study throws our understanding of gene regulation for a loop
(via sciencedaily.com) Original source To function properly, the genetic material is highly organized into loop structures that often bring together widely separated sections of the genome critical to the regulation of gene activity. Scientists now address how these loops can help repress or silence gene activity, with potentially far-reaching effects on human health.
Published Spider venom heart drug a step closer
(via sciencedaily.com) Original source A molecule sourced from funnel web spider venom shows promise as a safe and effective future drug for heart attacks.
Published Machine learning reveals sources of heterogeneity among cells in our bodies
(via sciencedaily.com) Original source A team of scientists discovered the secrets of cell variability in our bodies. The findings of this research are expected to have far-reaching effects, such as improvement in the efficacy of chemotherapy treatments, or set a new paradigm in the study of antibiotic-resistant bacteria.
Published Males of newly described Australian burrowing scorpions have a big tail to tell
(via sciencedaily.com) Original source A study has found some surprising features in two new species of burrowing scorpions, including a very strangely shaped 'tail tip' and some 'sexy' anatomy features. Terrestrial biologists have taken a closer look at two new species of the mysterious Urodacus genus of burrowing scorpions endemic to Australia -- only to find a big difference in their tails compared to other species.
Published Perfecting 3D-printed blood vessels with pores
(via sciencedaily.com) Original source Due to the substantial clinical demand for artificial small-diameter vessels (SDVs), numerous commercial products have emerged. However, the majority of existing artificial SDVs lack an endothelial layer, leading to thrombosis. Fabricating artificial SDVs with a consistently uniform endothelial layer and adequate mechanical properties has proven exceptionally challenging. A research team has now induced spontaneous cell assembly and endothelialization through internal pores.
Published Surprisingly simple model explains how brain cells organize and connect
(via sciencedaily.com) Original source A new study by physicists and neuroscientists describes how connectivity among neurons comes about through general principles of networking and self-organization, rather than the biological features of an individual organism.
Published Surprise discovery: For most animals, sperm quality does not reduce with age
(via sciencedaily.com) Original source In humans, male fertility and sperm fitness decline with age, but scientists have made the surprising discovery that this pattern is not consistent in other animals. The team assessed the results of 379 studies which covered a wide range of animals, including mammals, insects, birds, and fish.
Published Glowing COVID-19 diagnostic test prototype produces results in one minute
(via sciencedaily.com) Original source Cold, flu and COVID-19 season brings that now-familiar ritual: swab, wait, look at the result. But what if, instead of taking 15 minutes or more, a test could quickly determine whether you have COVID-19 with a glowing chemical? In a new study, researchers describe a potential COVID-19 test inspired by bioluminescence. Using a molecule found in crustaceans, they have developed a rapid approach that detects SARS-CoV-2 protein comparably to one used in vaccine research.
Published Study uncovers mechanics of machete-like 'tail-whipping' in thresher sharks
(via sciencedaily.com) Original source Like Indiana Jones, thresher sharks have mastered the art of the whip using their tails. Now, new research provides intricate details showing that vertebrae anatomy might support the mechanics of extreme body bending in thresher sharks, enabling these expert hunters to weaponize their tails. Using micro-CT scanning similar to CAT scans in humans, and two-dimensional shape analysis, results of the study suggest vertebral anatomy and mineralized microstructure meet the demands required for fast swimming and tail-whipping behavior seen in these species.
Published New technology for conducting deep-sea research on fragile organisms
(via sciencedaily.com) Original source Scientists have successfully demonstrated new technologies that can obtain preserved tissue and high-resolution 3D images within minutes of encountering some of the most fragile animals in the deep ocean.
