Tissue patterning is an important process during embryo formation, which ensures that groups of cells are arranged in an appropriate manner that allows them to function properly.
Read moreNext-generation solar cells that mimic photosynthesis with biological material may give new meaning to the term 'green technology.' Adding the protein bacteriorhodopsin (bR) to perovskite solar cells boosted the efficiency of the devices in a series of laboratory tests, according to an international team of researchers.
Read moreSwapping a single amino acid in a simple bacterial protein changes its structure and function, revealing the effects of complex gene evolution, finds a new study. The study — conducted using E. coli bacteria — can help researchers to better understand the evolution of transporter proteins and their role in drug resistance.
Read moreA research team has created a third approach to engineering proteins that uses deep learning to distill the fundamental features of proteins directly from their amino acid sequence without the need for additional information.
Read moreUsing high-throughput next-generation sequencing technology, a researcher found similarities in the folding tendencies among a family of RNA molecules called riboswitches, which play a pivotal role in gene expression.
Read moreFrench investigators have described development of resistance to one of the last resort therapies used to treat extremely drug-resistant Pseudomonas aeruginosa. That resistance arose in a single patient over a scant 22 days. They subsequently identified the single nucleotide mutation in P. aeruginosa that caused the resistance.
Read moreScientists demonstrate a new approach in fluorescence microscopy that can be used to locate individual biomolecules in 3D space with nanometer-scale precision.
Read moreNew research presents the first demonstration of a specific difference in sperm function associated with sex ratio skewing.
Read moreCentromeres are the chromosomal domains at which the kinetochore, a protein complex required for the correct separation of chromosomes during mitosis and meiosis, is assembled. The incorporation of the histone variant CenH3 into centromeric nucleosomes is a prerequisite for the proper assembly and function of the kinetochore. A new study describes the chaperone protein NASPSIM3 and how it affects the depositioning of CenH3.
Read moreA high-resolution bioprinting process has been developed: Cells can now be embedded in a 3D matrix printed with micrometer precision — at a printing speed of one meter per second, orders of magnitude faster than previously possible. Tissue growth and the behavior of cells can be controlled and investigated particularly well by embedding the cells in a delicate 3D framework. This is achieved using so called 'bioprinting' techniques.
