New nanotechnology could aid stem cell transplantation research

Nanotechnology developed at Rutgers University-New Brunswick could boost research on stem cell transplantation, which may help people with Alzheimer’s disease, Parkinson’s disease, other neurodegenerative diseases and central nervous system injuries. The scientists’ nanotechnology platform uses special tiny rods with nickel and gold to detect microRNA inside exosomes. Exosomes – tiny …

Unlocking the mysteries of plant cell morphology

Credit: CC0 Public Domain The discovery of the mechanics and molecular mechanism that dictate cell shape formation in plants by a team of McGill researchers offers new clues about the fundamental processes governing tissue formation in multicellular organisms. Plants are made of cells that come in a wide array of …

Space station cell study seeks causes of major diseases

Dopaminergic neurons growing in a culture dish (20x magnification). A skin biopsy from a patient with Parkinson’s disease was reprogrammed into induced pluripotent stem cells. The stem cells were then differentiated into dopaminergic neurons (green), the same cells that are lost in Parkinson’s disease patients. Work is under way to …

Study gives insight into sun-induced DNA damage and cell repair

Rad4/XPC protein dynamically engages with the DNA duplex to ‘open’ and recognize the 6–4 photoproduct (6–4PP), a major DNA lesion induced by sunlight. Here is presented a new structure that shows how the 6–4PP is completely flipped out of the DNA double helix by Rad4/XPC protein that initiates nucleotide excision …

Scientists gain new insights into the mechanisms of cell division

Using laser microsurgery, they were able to remove the centrioles from within the centrosome at different stages of mitosis without destroying the entire structure. Credit: © Alexander Dammermann Mitosis is the process by which the genetic information encoded on chromosomes is equally distributed to two daughter cells, a fundamental feature …

Activity of fuel cell catalysts doubled

An interdisciplinary research team at the Technical University of Munich (TUM) has succeeded in optimizing the size of platinum nanoparticles for fuel cell catalysis so that the new catalysts are twice as good as the currently best commercially available processes. The picture shows the first authors: Dr. Batyr Garlyyev, Kathrin …
