New insights into ribosome self-assembly
Date: Feb-14-2014Ribosomes, the cellular machines that build proteins, are themselves made up of dozens of proteins and a few looping strands of RNA. A new study, reported in the journal Nature, offers new clues about how the ribosome, the master assembler of proteins, also assembles itself."The ribosome has more than 50 different parts - it has the complexity of a sewing machine in terms of the number of parts," said University of Illinois physics professor Taekjip Ha, who led the research with U. of I.
Brain process takes paper shape
Date: Feb-14-2014A paper-based device that mimics the electrochemical signalling in the human brain has been created by a group of researchers from China.The thin-film transistor (TFT) has been designed to replicate the junction between two neurons, known as a biological synapse, and could become a key component in the development of artificial neural networks, which could be utilised in a range of fields from robotics to computer processing.
A step towards detecting and targeting the pre-leukemic stem cell
Date: Feb-14-2014Cancer researchers led by stem cell scientist Dr. John Dick have discovered a pre-leukemic stem cell that may be the first step in initiating disease and also the culprit that evades therapy and triggers relapse in patients with acute myeloid leukemia (AML).The research, published online in Nature is a significant leap in understanding the steps that a normal cell has to go through as it turns into AML, says Dr. Dick, and sets the stage to advance personalized cancer medicine by potentially identifying individuals who might benefit from targeting the pre-leukemic stem cell.

Same brain region activated in appreciation of mathematical beauty as in appreciation of great art or music
Date: Feb-14-2014People who appreciate the beauty of mathematics activate the same part of their brain when they look at aesthetically pleasing formula as others do when appreciating art or music, suggesting that there is a neurobiological basis to beauty.There are many different sources of beauty - a beautiful face, a picturesque landscape, a great symphony are all examples of beauty derived from sensory experiences. But there are other, highly intellectual sources of beauty.

Exercise improves heart function by targeting cellular powerhouses
Date: Feb-14-2014Whether lifting weights in a gym or just walking around the block, exercise has many benefits, such as helping people lose weight and build stronger muscles. Some studies suggest that it may reduce the risk of developing cancer and other diseases. Researchers now report in ACS' Journal of Proteome Research that moderate, long-term physical activity appears to improve cardiovascular health in mice by targeting the heart cells' powerhouses - the mitochondria.
