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.

'Nanomotor Lithography' Answers Call for Affordable, Simpler Device Manufacturing
What does it take to fabricate electronic and medical devices tinier than a fraction of a human hair? Nanoengineers at the University of California, San Diego recently invented a new method of lithography in which nanoscale robots swim over the surface of light-sensitive material to create complex surface patterns that form the sensors and electronics components on nanoscale devices. Their research, published recently in the journal Nature Communications, offers a simpler and more affordable alternative to the high cost and complexity of current
EEG Test to Help Understand And Treat Schizophrenia
Researchers at University of California, San Diego School of Medicine have validated an EEG test to study and treat schizophrenia. The findings, published in two separate studies, offer a clinical test that could be used to help diagnose persons at risk for developing mental illness later in life, as well as an approach for measuring the efficacies of different treatment options.
Engineers Develop Novel Ultrasound Technology to Screen for Heart Conditions
Engineers at the University of California, San Diego have determined for the first time the impact of a ring-shaped vortex on transporting blood flow in normal and abnormal ventricles within the human heart. They worked with cardiologists at the Non-Invasive Cardiology Laboratory at Gregorio Marañon Hospital, in Madrid, Spain.
New Solar Power Material Converts 90% of Captured Light into Heat
A multidisciplinary engineering team at the University of California, San Diego developed a new nanoparticle-based material for concentrating solar power plants designed to absorb and convert to heat more than 90 percent of the sunlight it captures. The new material can also withstand temperatures greater than 700 degrees Celsius and survive many years outdoors in spite of exposure to air and humidity. Their work, funded by the U.S. Department of Energy's SunShot program, was published recently in two separate articles in the journal
Viral Switches Share a Shape
A hinge in the RNA genome of the virus that causes hepatitis C works like a switch that can be flipped to prevent it from replicating in infected cells. Scientists have discovered that this shape is shared by several other viruses—among them one that kills cancer cells. That's Seneca Valley virus, which seems harmless to healthy human cells but lethal to cancer stem cells.
