Some fish swim in synchrony. Others, it turns out, breathe in synchrony. This is true for Arapaimas, an obligate air-breathing species living in the Amazon. A new study in Communications Biology, led by the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) in collaboration with the Cluster of Excellence “Science of Intelligence”, has demonstrated for the first time that arapaima juveniles gather by the hundreds to synchronize their trips to the water surface with split-second precision, most likely to avoid predators and maximize survival and efficiency. The principle behind this behavior could also help inform mathematical models for synchronizing heterogeneous groups of robots or drone swarms.
Cells have surface receptors that couple to proteins and other molecules to initiate or inhibit certain behaviors. Typically, the number of these receptors increases as the cell matures, but researchers have now identified that one receptor influences cell behavior much earlier than previously thought and appears to help trigger the cell differentiation process to form neurons.
Researchers at HSE University, in collaboration with colleagues from other Russian institutions, have identified which mutations in the ACVRL1 gene may be pathogenic in patients with pulmonary arterial hypertension. The team modelled how genetic variations affect ATP binding to the protein—a process essential for transmitting signals required for normal vascular function. The researchers found that 20 of the 32 variants studied can disrupt signal transmission and are therefore likely to cause disease. The findings have been published in the Journal of Structural Biology.
MD4SB will establish an infrastructure for the dynamic description of biological macromolecules, connecting three major European Research Infrastructures (Instruct-ERIC, ELIXIR, and EU-OPENSCREEN ERIC) with three of Europe's largest supercomputing centres (BSC-CNS, CINECA, and JSC).
The project will facilitate the use of molecular simulations to understand how biomacromolecules function, advance the molecular description of diseases, and accelerate drug discovery.
Coordinated by IRB Barcelona, the project brings together 25 partners across 8 countries and incorporates Almirall, Sanofi, and other pharmaceutical companies to provide feedback and evaluate the practical usefulness of the platform in industrial settings. The IRB Barcelona spin-off company Nostrum Biodiscovery will bridge the gap between academic groups and pharmaceutical companies.
Researchers studied the microbes associated with historical middens conserved in Greenland’s permafrost, left behind by Paleo-Inuit, ancient Norse, and early modern Inuit. These middens harbored biodiverse bacterial communities – including many unknown taxa – that were especially rich in human- and animal-associated groups. The authors concluded that microbial traces of human activities such as defecation, livestock farming, and seal hunting can linger for centuries in Arctic middens. They also found a wide range of antimicrobial resistance genes in the bacterial genomes. However, the limited outward spread of potential pathogens away from the frozen core of the middens means that they currently pose little risk to public health.
Researchers from The University of Osaka found that using a sequence analysis approach that incorporates awareness of insertions and deletions in extramembrane domains enabled accurate reconstruction of ancestral rhodopsins that folded correctly and functioned as predicted when expressed in E. coli. The researchers’ ConsistASR analytical pipeline could be used to engineer other ancestral proteins in the future.
