Forward or backward? New pathways for protons in water or methanol

October 8, 2019 0 Comments Biochemistry, Chemistry, Energy and Resources, Fuel Cells, Inorganic Chemistry, Nature of Water, Organic Chemistry, Physics

A collaborative ultrafast spectroscopy and ab initio molecular dynamics simulations study shows that proton vacancies in the form of hydroxide/methoxide ions are as relevant for proton transfer between acids and bases as hydrated excess protons, thus pointing for a clear demand for refinement of the microscopic picture for aqueous proton transport – in solution as well as in hydrogen fuel cells or transmembrane proteins – away from currently often assumed dominant role of hydrated excess protons.

Researchers have developed 3-dimensional human tissue culture models of pediatric and adult brain cancers in a brain-mimicking microenvironment, that includes brain-derived extracellular matrix (ECM) — the complex network of proteins and amino acids with bound sugars that not only provides support for surrounding neural tissue, but also helps to guide cell growth and development. The development represents a significant advancement for the study of brain tumor biology and pharmacological response.

New method to purify cell types to high purity

October 3, 2019 0 Comments Batteries, Biochemistry, Biotechnology, Cancer, Developmental Biology, Genetics, Lymphoma, Organic Chemistry, Stem Cells

Current biology research relies on the ability to purify cell types using antibodies or transgenic constructs. However, antibody availability is often limited, and genetic manipulation is labor intensive or sometimes impossible. To date, no universal method exists to enrich for cell types without a priori knowledge of cell type markers. Here, we propose GateID, a computational method that combines single-cell transcriptomics with FACS index sorting to purify cell types using only native cellular properties.
