| Computer simulations visualize ion flux Posted: 02 Sep 2014 08:49 AM PDT Pharmacologists have investigated how ion flux through a voltage gated sodium ion channel works in detail. Since this process is incredibly fast -- up to 100 million ions per seconds -- computer simulations were performed to visualize sodium flux 'in slow motion.' |
| Can a stack of computer servers survive an earthquake? Posted: 02 Sep 2014 08:42 AM PDT In high-seismic regions, new facilities often are engineered with passive protective systems that provide overall seismic protection. But often, existing facilities are conventional fixed-base buildings in which seismic demands on sensitive equipment located within are significantly amplified. In such buildings, sensitive equipment needs to be secured from these damaging earthquake effects. |
| Posted: 02 Sep 2014 06:34 AM PDT In the quantum world, making the simple atom behave is one thing, but making the more complex molecule behave is another story. Now scientists have figured out an elegant way to stop a molecule from tumbling so that its potential for new applications, such as quantum computing, can be harnessed: shine a single laser on a trapped molecule and it instantly cools to the temperature of outer space, stopping the rotation of the molecule. |
| Real tremors, or drug-seeking patient? New app can tell Posted: 29 Aug 2014 05:42 AM PDT A new smartphone uses data from built-in accelerometer to measure the frequency of alcohol withdrawal tremors. Withdrawal is a potentially fatal condition that is easily treated with benzodiazepine drugs, a class of sedatives used to treat alcohol withdrawal, anxiety, seizures, insomnia and more. But physicians are often reluctant to prescribe them because they're frequently abused and can be dangerous when mixed with other drugs, especially alcohol and opiates. |
