The part of our sleep cycle involving Rapid Eye Movement (REM), otherwise known as paradoxical sleep, is a crucial phase of sleep identified in mammals and birds involving the random … Continue Reading Researchers identify neurons responsible for rapid eye movements/REM during sleep.
Flagella and cilia are slender organellar protrusions of the eukaryotic cell membrane with sensory and motor function. Flagella and cilia are similar in that they share a microtubule-based cytoskeleton called … Continue Reading Researchers identify lipid responsible for keeping brain fluid moving.
Mammalian embryos start out as a small group of identical cells. Then at an early stage, some of these cells take up an internal position within the embryo. These internal … Continue Reading Researchers visualise mammalian embryo formation for the first time.
A new blood test may more accurately identify blood signatures, or biomarkers, for Parkinson’s disease (PD), according to a new study published in the journal Movement Disorders. The study, conducted … Continue Reading New blood test identifies genetic risk factor for Parkinson’s disease in human studies.
Scientists from the CNRS, INSERM and Université de Limoges have demonstrated that the production of type E immunoglobulins (IgE)2 by B lymphocytes induces a loss in their mobility and the … Continue Reading Researchers map programmed cell death in immune cells to prevent allergy.
A new study from the Albert Einstein College of Medicine and the University of Pittsburgh details how cells with low levels of the profilin 1 protein in breast tumours increase their … Continue Reading Researchers identify protein crucial for breast cancer metastasis ‘scaffolding’.
Researchers at Massachusetts General Hospital (MGH) and Massachusetts Institute of Technology (MIT) have added another piece to the complex puzzle of how the brain controls one of the most essential … Continue Reading Optogenetics study identifies neurons important for induction of natural REM sleep.
Defective cilia can lead to a host of diseases and conditions in the human body, from rare, inherited bone malformations to blindness, male infertility, kidney disease and obesity. It is … Continue Reading Researchers video and measure tubulin transport in cilia for the first time.
Researchers at University of California, San Diego Skaggs School and the University of Southern California report the first crystal structure of the cellular receptor CXCR4 bound to an immune signaling … Continue Reading Researchers capture the 3d structure of a chemokine and its receptor for the first time.
Cells have finger-like projections that they use to feel their surroundings. They can detect the chemical environment and they can ‘feel’ their physical surroundings using ultrasensitive sensors. New research from … Continue Reading New mechanism of cell movement identified and imaged for the first time.
New technology advances eye tracking as biomarker for brain function and recovery from brain injury.
Researchers at NYU Langone Medical Center and the Steven & Alexandra Cohen Veterans Center have developed new technology that can assess the location and impact of a brain injury merely … Continue Reading New technology advances eye tracking as biomarker for brain function and recovery from brain injury.
By blocking a widespread enzyme, Centenary Institute amd Sydney Medical School researchers have shown they can slow down the movement of cells and potentially stop tumours from spreading and growing. … Continue Reading Researchers identify and observe enzyme slowing down living cancer cells.
