Titan: World's Fastest Supercomputer Unleashed
2012-10-29 10:21:25

Michael Harper for redOrbit.com — Your Universe Online The Oak Ridge National Laboratory (ORNL) has created a machine capable of doing the unthinkable. In fact, it´s capabilities not only sound impossible, they sound fictional. By combining traditional CPUs with graphical processing units (GPUs), the Titan Supercomputer capable of spitting out 20 petaflops, making it 10 times more powerful than ORNL´s previous Jaguar supercomputer. For the uninitiated, a petaflop, says...

Multicellular bacteria transmit electrons across relatively enormous distances A multinational research team has discovered filamentous bacteria that function as living power cables in order to transmit electrons thousands of cell lengths away. The Desulfobulbus bacterial cells, which are only a few thousandths of a millimeter long each, are so tiny that they are invisible to the naked eye. And yet, under the right circumstances, they form a multicellular filament that can transmit...

RNA-world Hypothesis Under The Microscope
2012-10-15 05:27:46

redOrbit Staff & Wire Reports - Your Universe Online A chemical model developed by a team of US researchers shows how the Earth's first life forms may have packaged the genetic coding material known as ribonucleic acid (RNA), demonstrating one of the earliest steps that could have paved the way for the formation of cellular life some four billion years ago. The Penn State University scientists behind the project used a type of macromolecule called polymers to create primitive...

Body's Own Recycling System

Researchers discover "molecular emergency brake" in charge of regulating self-digestion Times of distress literally eat away at the core of starving cells: They start to digest their own parts and recycle them for metabolic purposes. This process — called autophagy — also plays a role in immune defense. In that context, however, the digestive machinery is switched on for an entirely different purpose: the elimination of pathogens that have invaded the body. Now, Prof. Ingo...

An international team of scientists have shown at an unprecedented level of detail how cells prioritize the repair of genes containing potentially dangerous damage. The research, published in the journal Nature and involving academics from the University of Bristol, the Institut Jacques-Monod in France and Rockefeller University in the US, studied the action of individual molecules in order to understand how cellular repair pathways are triggered. The genetic information that forms the...

'Promiscuous' Enzymes Still Prevalent In Metabolism Shown By New Study
2012-08-31 13:12:26

Challenges fundamental notion of enzyme specificity and efficiency Open an undergraduate biochemistry textbook and you will learn that enzymes are highly efficient and specific in catalyzing chemical reactions in living organisms, and that they evolved to this state from their “sloppy” and “promiscuous” ancestors to allow cells to grow more efficiently. This fundamental paradigm is being challenged in a new study by bioengineers at the University of California, San...

Why Cells And Organelles Don't Get Stuck

Researchers explain 'hydration repulsion' between biomembranes Biomembranes enclose biological cells like a skin. They also surround organelles that carry out important functions in metabolism and cell division. Scientists have long known in principle how biomembranes are built up, and also that water molecules play a role in maintaining the optimal distance between neighboring membranes–otherwise they could not fulfill their vital functions. Now, with the help of computer...

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 &...
