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.

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.
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.
A promising new approach for treating leukemia - the essential role of the BRG1 gene
Date: Feb-14-2014A group of researchers at the Institute for Research in Immunology and Cancer (IRIC) of Université de Montréal discovered a promising new approach to treating leukemia by disarming a gene that is responsible for tumor progression. That gene, known as Brg1 is a key regulator of leukemia stem cells that are the root cause of the disease, resistance to treatment and relapse.
A new pathway for fear discovered deep within the brain
Date: Feb-14-2014Fear is primal. In the wild, it serves as a protective mechanism, allowing animals to avoid predators or other perceived threats. For humans, fear is much more complex. A normal amount keeps us safe from danger. But in extreme cases, like post-traumatic stress disorder (PTSD), too much fear can prevent people from living healthy, productive lives. Researchers are actively working to understand how the brain translates fear into action.
In mouse model, novel compound keeps Parkinson's symptoms at bay
Date: Feb-14-2014Scientists report that they have developed a novel compound that appears to protect mice against developing movement problems associated with Parkinson's disease (PD). The research, which could one day in the future translate into a therapy that could halt the progression of PD and thereby prevent the symptoms of the disease, appears in ACS' Journal of Medicinal Chemistry.Onyou Hwang, Ki Duk Park and colleagues explain that PD, which affects an estimated 4 million to 10 million people worldwide, is a progressive movement disorder with no known cure.
