Developing new fluorescent metal sensors to peer into the gastrointestinal tract

A University of Houston researcher is developing a new set of metal sensors that will be able to function in the gastrointestinal tract, a low oxygen environment, to examine how gut bacteria respond when trace metal nutrients, like iron and zinc, are thrown out of balance either through diet or disease.

Characteristics of electron emission from irradiated biomolecules

When fast-moving ions cross paths with large biomolecules, the resulting collisions produce many low-energy electrons which can go on to ionise the molecules even further. To fully understand how biological structures are affected by this radiation, it is important for physicists to measure how electrons are scattered during collisions.

Study shows how mast cells regulate calcium levels to control the immune response

Instead of protecting us, the immune system can sometimes go awry, as in the case of autoimmune diseases and allergies. An Ludwig-Maximilian-Universitaet (LMU) in Munich team has dissected how mast cells regulate their calcium levels to keep the immune response under control.

Analysis of the SARS-CoV-2 proteome via visual tools

Now, a new study published on the preprint server bioRxiv* in July 2020 shows how this can be advanced at a greater speed by combining experimental results with homology models obtained by high-throughput pipelines. This will help produce new hypotheses that will show novel druggable targets for effective drug development.

Age-related hearing loss mainly caused by damage to hair cells, study shows

In a new study of human ear tissues, hearing scientists have demonstrated that age-related hearing loss, also called presbycusis, is mainly caused by damage to hair cells, the sensory cells in the inner ear that transform sound-induced vibrations into the electrical signals that are relayed to the brain by the auditory nerve.

Scientists identify a new role for covalent linker in transmembrane ion channels

In the molecular-level world of ion channels - passageways through membranes that carry signals in a cell's environment and allow it to respond - researchers have debated about the role of a small piece of the channel called a linker, says computational biophysicist Jianhan Chen at the University of Massachusetts Amherst.
