During your lifetime, the cells in your body divide many trillions of times. Iain Cheeseman, an associate professor of biology at MIT, has spent his career studying how cells control this process, which is critical to ensuring that the correct genetic information is passed down from generation to generation.
Yeast geneticists report they have developed a novel tool - dubbed the 'telomerator' - that could redefine the limits of synthetic biology and advance how successfully living things can be engineered or constructed in the laboratory based on an organism's genetic, chemical base-pair structure.
Scientists disclosed a new method to convert lignin, a biomass waste product, into simple chemicals. The innovation is an important step toward replacing petroleum-based fuels and chemicals with biorenewable materials.
Scientists have found a new way to dramatically increase crop yields. The team has discovered a set of gene variations that boost fruit production in the tomato plant by as much as 100 percent. Plant breeders will be able to combine different gene variants to create an optimal plant architecture for particular varieties and growing conditions. The set will enable farmers to maximize yield in tomatoes and potentially other flowering plants, including crops like soybeans.
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.
