Article Synopsis
- Scientists are studying a special protein from a tiny animal called the tardigrade to learn how it can survive tough conditions and use that knowledge for medicine and space research.
- The protein, named Dsup, helps protect DNA from damage caused by harmful things, like radiation.
- Researchers discovered that Dsup has a flexible structure and can sort of "hug" DNA in a loose way, which helps keep it safe.
We have studied the effect of calcium ions (Ca) at various concentrations on the structure of lipid vesicles in the presence of amyloid-beta peptide Aβ(25-35). In particular, we have investigated the influence of calcium ions on the formation of recently documented bicelle-like structures (BLSs) emerged as a result of Aβ(25-35) triggered membrane disintegration. First, we have shown by using small-angle X-ray and neutron scattering that peptide molecules rigidify the lipid bilayer of gel phase DPPC unilamellar vesicles (ULVs), while addition of the calcium ions to the system hinders this effect of Aβ(25-35).

With and without hydrocarbon solutions, the hybrid micelles exhibit the same values of viscosity at shear rates typical for hydraulic fracturing (HF) tests, as solutions of polymer-free WLMs. Therefore, similar to WLMs of surfactants, they could be applied as thickeners in HF fluids without breakers.

- Ribosome biogenesis is a complex and energy-demanding process, where any small errors can lead to serious consequences for the cell, including death.
- Biogenesis factors like RimP play a crucial role in this process by assisting the proper assembly of ribosomal proteins and rRNA.
- This study details how RimP interacts with the 30S ribosomal subunit in Staphylococcus aureus, providing insights into its binding and structural dynamics through advanced techniques like cryo-EM and NMR spectroscopy.
In this study, we aimed to design and research proton-conducting membranes based on Aquivion-type material that had been modified with detonation nanodiamonds (particle size 4-5 nm, 0.25-5.0 wt.
