New defibrillator signals doctor of patient's irregular heartbeat or device malfunction

...ts abnormally or if the device malfunctions, e.g., battery failure. When a patient's status changes, a built-in microchip of Biotronik's Lumos DR-T implantable cardioverter defibrillator (ICD) sends a signal to a satellite via a small transmitter that can be placed on a nightstand, worn on a belt or kept...

Methamphetamine Abuse, HIV Infection Cause Changes in Brain Structure

North & South American researchers find architectural abnormalities in T. cruzi ribosome

...napshot. Frank and his colleagues have developed a battery of complex mathematical techniques to reconcile the images at different angles. From a total of up to 30,000 ribosome images, they assemble a final three-dimensional image of a single ribosome. A ribosome binds to mRNA with its small subunit. In the...

New study finds how cells with damaged DNA alert the immune system
