Our cells breathe and digest, as does the organism as a whole. They indeed use oxygen to draw the energy contained in the nutrients they ingest, before discarding the waste, as carbon dioxide and water. Glucose is a preferred nutrient for the cells. Its digestion occurs in the cytoplasm, in the absence of oxygen, and leads to the formation of pyruvate and a small amount of energy. Pyruvate is then carried into mitochondria, the cell's power plants, for a complete burning, thus providing a...

Amino acid consumption associated with how fast cancer cells divide For almost a century, researchers have known that cancer cells have peculiar appetites, devouring glucose in ways that normal cells do not. But glucose uptake may tell only part of cancer's metabolic story. Researchers from the Broad Institute and Massachusetts General Hospital looked across 60 well-studied cancer cell lines, analyzing which of more than 200 metabolites were consumed or released by the fastest dividing...

The scientific and technological literature is abuzz with nanotechnology and its manufacturing and medical applications. But it is in an area with a less glitzy aura-plant sciences-where nanotechnology advancements are contributing dramatically to agriculture. Researchers at Iowa State University have now demonstrated the ability to deliver proteins and DNA into plant cells, simultaneously. This is important because it now opens up opportunities for more sophisticated and targeted plant...

Scientists Create Rewritable DNA

Scientists have found a way to create rewritable digital data storage in DNA through means similar to binary coding. The researchers worked to reapply natural enzymes adapted from bacteria to flip specific genetic sequences of DNA back and forth at will. The scientists, who all work in the Department of Bioengineering at Stanford University Medical Center, said their method essentially works like that of binary computer coding. "Essentially, if the DNA section points in one...

Microscopes provide valuable insights in the structure and dynamics of cells, in particular when the latter remain in their natural environment. However, this is very difficult especially for higher organisms. Researchers of Karlsruhe Institute of Technology (KIT), the Max Planck Institute for Polymer Research, Mainz, and the American National Institutes of Health (NIH) have now developed a new method to visualize cell structures of an eighth of a micrometer in size in living fish larvae. It...

DNA Replication Protein Plays Role In Cancer
2012-05-14 08:46:39

The foundation of biological inheritance is DNA replication This is a coordinated process in which DNA is copied at hundreds of thousands of different sites across the genome at the same time. If the copying mechanism doesn't work properly, the result may be cells with missing or extra genetic material, a hallmark of the genomic instability seen in most birth defects and cancers. Scientists at the University of North Carolina School of Medicine have discovered a protein known as Cdt1....

Ribonucleoprotein granules exit the nucleus via a budding mechanism akin to herpes-type viruses The movement of genetic materials, such as RNA and ribosomes, from the nucleus to the cytoplasm is a critical component in a cell's ability to make the proteins necessary for essential biological functions. Until now, it was believed the nuclear pore complex was the sole pathway between the cell nucleus and cytoplasm for these materials. New evidence published in Cell by Vivian Budnik, PhD,...

Scientists from the Medical Research Council (MRC) Institute of Genetics and Molecular Medicine (IGMM) at the University of Edinburgh have discovered an enzyme that corrects the most common mistake in mammalian DNA. The mistake is the inclusion of individual bits of RNA within the DNA sequence, which the researchers found occurs more than a million times in each cell as it divides. The findings, published in Cell, suggest the RNase H2 enzyme is central to an important DNA repair mechanism...

Journal of Biological Chemistry: Mechanism of bacterial transport system published In order to interact with the environment, bacteria secrete a whole arsenal of proteins. Researchers have now found how one of the transportation systems used for this purpose — the type VI secretion system — works for the single-celled organism Agrobacterium tumefaciens. They have identified the relevant transport proteins and their energy suppliers. With colleagues at the Academia Sinica in...

Cell (journal)
2012-06-04 14:15:36

Cell is a peer-reviewed scientific journal founded by Benjamin Lewin in January 1974 with the sponsorship of MIT Press. Lewin bought the rights to the journal in 1986 and published it under his own publishing arm Cell Press. Cell Press was sold to Elsevier in 1999, which currently publishes Cell twice monthly. Cell Press publishes several biomedical journals, including Cell, Neuron, Immunity, Molecular Cell, Developmental Cell, Cancer Cell, Current Biology, Structure, Chemistry &...

  • A 'bachelor seal'; a young male seal which is prevented from mating by its herd's older males (mated bulls defending their territory).
This comes from the Russian word for 'bachelors.'
