The Evolution of Proteins: A Journey Through 3.8 Billion Years

Research by Gustavo Caetano-Anollés and Fayez Aziz, University of Illinois, reveals a “big bang” during evolution of protein subunits known as domains. The team looked for protein relationships and domain recruitment into proteins over 3.8 billion years across all taxonomic units. Their results could have implications for vaccine development and disease management. Credit: Fred...

LUCA Device: Precise Thyroid Cancer Screening

The LUCA Device Reveals High Precision in Thyroid Cancer Cells ScreeningThyroid nodules are a usual pathology with 19-76% when screened with ultrasound, with more remarkable regularities in women. Present medical techniques used to examine this cancer consist of executing an ultrasound, adhered to by a Doppler ultrasound, and afterward a biopsy. However, sadly, these...

Piezo1: A Novel MS Cure

Targeting Piezo1 Protein May be a Brand New and Ideal Approach to Cure Multiple SclerosisIn a new College of California, Irvine-led research study, researchers discovered that a specific healthy protein prevented governing T cells (Tregs) from successfully doing their work in controlling the damaging results of inflammation in a version of multiple sclerosis (MS),...

Researchers Discover “Gorditas” and Other Unheard Types of Brain Cells

The newly described oligodendrocyte progenitor cells (green) contact long-distance neuronal axons (magenta) on the wall of the brain ventricles.According to a study published June 20 in Science, scientists discovered two types of glial cells in the brains of adult mice - an astrocyte and an oligodendrocyte progenitor cell - after pushing neural stem cells to...

Sustained Fast Rates of Evolution Explain Exactly How Tetrapods Advanced From Fish

The aerial scene depicts two Late Devonian early tetrapods – Ichthyostega and Acanthostega – coming out of the water to move on land. Footprints trail behind the animals to show a sense of movement.
