Study shows how proteins guide electrons to the right place
Cells need energy to function. Researchers at the University of Gothenburg can now explain how energy is guided in the cell by small atomic movements to reach its destination in the protein. Imitating these structural changes of the proteins could le.....»»
An evolutionarily conserved pathway that achieves a peaceful co-existence with genomic parasites
Transposable elements are mobile genetic elements that can relocate within the genome and disrupt the normal function of genes, but are at the same time a source of evolutionary diversity. The lab of Tugce Aktas at the Max Planck Institute for Molecu.....»»

Researchers at the University of Helsinki have discovered a new mechanism of action between the nutrient adaptation of intestinal stem cells and aging. The finding may make a difference when seeking ways to maintain the functional capacity of the agi.....»»
Cybersecurity teams recognized as key enablers of business goals
97% of office workers across the UK and US trust their cybersecurity team’s ability to prevent or minimize damage from cyberattacks, according to CybSafe. The study examining attitudes towards cybersecurity teams within organizations has uncovered.....»»
Probing proton pumping: New findings on protein folding in bacteriorhodopsin
When it comes to drug development, membrane proteins play a crucial role, with about 50% of drugs targeting these molecules. Understanding the function of these membrane proteins, which connect to the membranes of cells, is important for designing th.....»»
Examining how molecular orbitals determine stability
Carboxylic acid dianions (fumarate, maleate, and succinate) play a role in coordination chemistry and, to some extent, also in the biochemistry of body cells. An HZB team at BESSY II has now analyzed their electronic structures using RIXS in combinat.....»»
Apple Vision Pro crams 50 pixels into the area of one iPhone 15 pixel

Study finds high nitrogen fertilizer input enhances the microbial network complexity in paddy soil
In paddy field, flood-and-drain cycles produce variations in reduced and oxidized environments, which are appropriate habitats for a wide variety of microorganisms. Nitrogen (N) fertilization drives the structure and function of soil microbial commun.....»»
A sleeker facial recognition technology tested on Michelangelo"s David
Many people are familiar with facial recognition systems that unlock smartphones and game systems or allow access to our bank accounts online. But the current technology can require boxy projectors and lenses. Now, researchers report in Nano Letters.....»»
New research brings order to disordered proteins
Protein molecules lie at the heart of biology. Our typical understanding of proteins states that each type of protein has a specific three-dimensional shape that enables it to perform its function. This dogma is challenged by intrinsically disordered.....»»
Examining math anxiety among middle schoolers and how it affects their performance
Math anxiety, which can begin as early as kindergarten, negatively affects students' math performance both in the moment and throughout their math education. Most research focuses on the affective or physiological aspects of math anxiety—the feelin.....»»
Researchers discover molecular mechanism that influences the symmetrical shape of the style
Humans are attracted to symmetry: in our buildings, our gardens, in our potential partners. For plants, the symmetrical shapes of organs are a matter of survival because the form directly impacts the function......»»
