Researchers show simpler versions of the universal genetic code can still function in protein synthesis. In addition to understanding early primordial organisms, the research could lead to applications preventing non-natural genetically modified materials from entering the natural world.

Scientists have, for the first, time created a type of "cyborg" tissue by embedding a three-dimensional network of functional, bio-compatible nanoscale wires into engineered human tissues.

Scientists have developed a method for embedding networks of biocompatible nanoscale wires within engineered tissues. These networks -- which mark the first time that electronics and tissue have been truly merged in 3-D -- allow direct tissue sensing and potentially stimulation, a potential boon for development of engineered tissues that incorporate capabilities for monitoring and stimulation, and of devices for screening new drugs.

Among patients with suspected or known coronary artery disease, use of a method that applies computational fluid dynamics to derive certain data from computed tomographic (CT) angiography demonstrated improved diagnostic accuracy vs. CT angiography alone for the diagnosis of ischemia.

Treatment with an agent that blocks the oxidation of an important component of the mitochondrial membrane prevented the secondary damage of severe traumatic brain injury and preserved function that would otherwise have been impaired, according to a research team.

Is sleep learning possible? A new study has found that if certain odors are presented after tones during sleep, people will start sniffing when they hear the tones alone -- even when no odor is present -- both during sleep and, later, when awake. In other words, people can learn new information while they sleep, and this can unconsciously modify their waking behavior.

People who drive commercial vehicles, such as buses, taxis, trucks and airplanes, could be incorrectly reporting their symptoms of sleep apnea due to their fears of endangering their employment, according to a new study.

People who carry a “G” instead of an “A” at a specific spot in their genetic code have roughly a six-fold higher risk of developing certain types of brain tumors a study has found.

A novel blood test that predicts sudden death risk in heart failure patients is set to help physicians decide which patients would benefit from implantable cardioverter defibrillators (ICDs). Approximately 5 million patients in the US have heart failure, a condition where the heart is unable to pump blood adequately, and nearly 550,000 people are diagnosed annually. Heart failure is the single most common cause of admission to hospitals in the US.
