A team of researchers investigating the genome of a healthy supercentenarian since 2011 has found many somatic mutations – permanent changes in cells other than reproductive ones – that arose during the woman's lifetime. Led by Erik Sistermans and Henne Holstege from the VU University Medical Center in Amsterdam, the team recently published its findings in the journal Genome Research as reported by GenomeWeb.

Fear, Safety And the Role of Sleep in Human PTSD
The effectiveness of post-traumatic stress disorder (PTSD) treatment may hinge significantly upon sleep quality, report researchers at the University of California, San Diego School of Medicine and Veterans Affairs San Diego Healthcare System in a paper published today in the Journal of Neuroscience.
Finding Keys to Glioblastoma Therapeutic Resistance
Researchers at the University of California, San Diego School of Medicine have found one of the keys to why certain glioblastomas – the primary form of a deadly brain cancer – are resistant to drug therapy. The answer lies not in the DNA sequence of the tumor, but in its epigenetic signature. These findings have been published online as a priority report in the journal Oncotarget.
Severe Drought Is Causing the Western US to Rise
The severe drought gripping the western United States in recent years is changing the landscape well beyond localized effects of water restrictions and browning lawns. Scientists at Scripps Institution of Oceanography at UC San Diego have now discovered that the growing, broad-scale loss of water is causing the entire western U.S. to rise up like an uncoiled spring.
Researchers Find Security Flaws in Backscatter X-ray Scanners
A team of researchers from the University of California, San Diego, the University of Michigan, and Johns Hopkins University have discovered several security vulnerabilities in full-body backscatter X-ray scanners deployed to U.S. airports between 2009 and 2013.
New Mouse Model Points to Therapy for Liver Disease
Non-alcoholic fatty liver disease (NAFLD) is a common affliction, affecting almost 30 percent of Americans, with a significant number suffering from its most severe form, called non-alcoholic steatohepatitis or NASH, which can lead to cirrhosis and liver cancer. In recent years, NASH has become the leading cause of liver transplantation.
