#1: Unusual RNAs Linked To Chronic Leukemia, May Help Treat It

A new and unusual class of genes plays an important role in the development of chronic lymphocytic leukemia (CLL), according to new research. At the same time, these genes may provide a new form of therapy for the disease. Read more

#2: Scientists Get First Glimpse At How Plants, Most Animals Repair UV-Damaged DNA

For the first time, researchers have observed exactly how some cells are able to repair DNA damage caused by the sun's ultraviolet (UV) radiation. The Ohio State University study revealed how the enzyme photolyase uses energy from visible light to repair UV damage. Read more

#3: Neanderthal Teeth Grew No Faster Than Comparable Modern Humans

Recent research suggested that ancient Neanderthals might have had an accelerated childhood compared to that of modern humans but that seems flawed, based on a new assessment by researchers from Ohio State University and the University of Newcastle . They found that the rate of tooth growth present in the Neanderthal fossils they examined was comparable to that of three different populations of modern humans. Read more

#4: Molecular Defect Found That May Cause Heart Failure

A new study has identified a molecular defect in cardiac cells that may be a fundamental cause of heart failure, a progressive weakening of the heart that leaves the organ unable to pump blood through the body. The findings show that specialized proteins called ryanodine receptors malfunction in the failing heart. These orm channels that become leaky, leading to calcium imbalances that prevent the heart from contracting effectively and relaxing adequately. The condition worsens until the heart can no longer work as a pump. (read more)
