Researchers have reconstituted cell division - complete with signals that direct molecular traffic - without the cell. Combining frog-egg extracts with lipid membranes that mimic the membrane of the cell, they built a cell-free system that recapitulates how the cleavage furrow is assembled.
Forty million people worldwide are living with Alzheimer's and this is only set to increase. But tiny brains grown in culture could help scientists learn more about this mysterious disease - and test new drugs.
Architecture imitates life, at least when it comes to those spiral ramps in multistory parking garages. Stacked and connecting parallel levels, the ramps are replications of helical structures found in a ubiquitous membrane structure in the cells of the body.
A bioengineering professor has received a $1.04 million grant that aims to regenerate cartilage tissue and reduce osteoarthritis using a patient's own stem cells, spurred through the injection of microscaffolding made of biodegradable polymers.
Scientists have devised a simple and versatile method, based on the geometry of the RNA molecule, which proved to be highly promising for analysing and understanding the complex interactions that characterise these molecules.
How does a normal cellular process derail and become unhealthy? A multi-institutional, international team studied cells found in breast and other types of connective tissue and discovered new information about cell transitions that take place during wound healing and cancer.
Researchers have developed a technique that co-opts an immune system already present in bacteria and archaea to turn off specific genes or sets of genes - creating a powerful tool for future research on genetics and related fields.
A new study at the University of Cambridge has allowed researchers to peer into unexplored regions of the genome and understand for the first time the role played by more than 250 genes key to cell growth and development.
A living cell, from one point of view, is a sort of sprawling protein factory that can churn out thousands of different proteins to order. Researchers are building on the basic idea of creating 'artificial cells' that might, in the future, enable us to control the production of proteins or other complex biological processes.
