When a Gene Is Worth Two: Same Gene Fulfills Different Biological Roles in Plants
March 22, 2013 — The notion that each gene can only codify for a single protein has been challenged for some years. Yet, the functional outcomes that may result from genes encoding more than one protein are still ... > full story -
Making Axons Branch and Grow to Help Nerve Regeneration After Injury
March 22, 2013 — One molecule makes nerve cells grow longer. Another one makes them grow branches. These new experimental manipulations have taken researchers a step closer to understanding how nerve cells are ... > full story -
Atherosclerosis: Specific microRNAs Promote Inflammation
March 22, 2013 — Atherosclerosis, an inflammatory reaction, is at the root of the most common forms of cardiovascular disease. Researchers have now identified a microRNA that plays a prominent role in the process, ... > full story -
Immune-Cell Therapy Could Strengthen Promising Melanoma Treatment
March 22, 2013 — Scientists have used newly developed nanotechnology chips (multidimensional and multiplexed immune monitoring assays) to successfully monitor T cells genetically engineered to attack melanoma. They ... > full story -
Spatial Memory: Mapping Blank Spots in the Cheeseboard Maze
March 22, 2013 — During learning, novel information is transformed into memory through the processing and encoding of information in neural circuits. Scientists have now uncovered a novel role for inhibitory ... > full story -
Quirky Lyme Disease Bacteria: Unlike Most Organisms, They Don't Need Iron, but Crave Manganese
March 21, 2013 — Scientists have confirmed that the pathogen that causes Lyme disease -- unlike any other known organism -- can exist without iron, a metal that all other life needs to make proteins and enzymes. ... > full story -
Breakthrough Could Lead to Cheaper, More Sustainable Chemical Production
March 21, 2013 — A new advance could enable the production of an important commodity chemical using carbon dioxide as a carbon source instead of petroleum. Carbon dioxide is basically free, and something the planet ... > full story -
Enzymes Allow DNA to Swap Information With Exotic Molecules
March 21, 2013 — Scientists have been hunting for a biological Rosetta Stone -- an enzyme allowing DNA's four-letter language to be written into a simpler (and potentially more ancient) molecule that may have existed ... > full story -
New Method Developed to Expand Blood Stem Cells for Bone Marrow Transplant
March 21, 2013 — More than 50,000 stem cell transplants are performed each year worldwide. Scientists may have solved a major issue of expanding adult hematopoietic stem cells outside the human body for clinical use ... > full story -
Discovery Could Increase Efficacy of Promising Cystic Fibrosis Drug
March 21, 2013 — Researchers believe they have found exactly how Kalydeco (Vx-770), the first drug of its kind to treat the underlying cause of cystic fibrosis, works and how to improve its effectiveness in the ... > full story
