How calcium ions get into the cellular power stations of plants

Microscopic image of the mitochondria in a root tip of Arabidopsis thaliana. The interior of the mitochondria (matrix) is marked by a fluorescent protein. Credit: University of Munster Calcium is a very special nutrient. In the cells of most living beings calcium ions function as so-called second messengers to transmit important signals. The same applies … Read more

Influence of nanoparticles, surrounding ions on formation of β-sheet structure in amyloid β proteins

Infrared (FT-IR) spectra and β-sheet ratio of Aβ peptides interacting with CeF3 NPs. The effect of CeF3 nanoparticles on amyloid beta protein structure is measured directly with FT-IR spectroscopy. The formation of secondary structure shows up as a feature in the IR spectrum. Credit: Masakazu Umezawa / Tokyo University of Science, License type: CC BY … Read more

Oxygen ions in Jupiter’s innermost radiation belts — ScienceDaily

Nearly 20 years after the end of NASA’s Galileo mission to Jupiter, scientists led by the Max Planck Institute for Solar System Research (MPS) in Germany have unlocked a new secret from the mission’s extensive data sets. For the first time, the research team was able to determine beyond doubt that the high-energy ions surrounding … Read more
