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.'

Magnetic substorms may sometimes be driven by different process than generally thought Posted: 02 Sep 2014 08:47 AM PDT Magnetic substorms, the disruptions in geomagnetic activity that cause brightening of aurora, may sometimes be driven by a different process than generally thought, a new study shows.

Scientists create renewable fossil fuel alternative using bacteria Posted: 02 Sep 2014 08:44 AM PDT Researchers have engineered the harmless gut bacteria E.coli to generate renewable propane. The development is a step towards commercial production of a source of fuel that could one day provide an alternative to fossil fuels. Propane is an appealing source of cleaner fuel because it has an existing global market.

Nano-forests to reveal secrets of cells Posted: 02 Sep 2014 06:42 AM PDT Vertical nanowires could be used for detailed studies of what happens on the surface of cells. The findings are important for pharmaceuticals research, among other applications. A group of researchers have now managed to make artificial cell membranes form across a large number of vertical nanowires, known as a 'nano-forest'.

Quantum control of molecules for ultra-fast computers: Single laser stops molecular tumbling motion instantly 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.

Rainfall monitoring: Mobile phones are taking over Posted: 02 Sep 2014 06:32 AM PDT Agriculture, water resource management, drought and flood warnings, etc.: rainfall monitoring is vital in many areas. But the observation networks remain insufficient. This is not the case for antennas for mobile telephones, which cover 90% of the world's inhabited areas. Besides transmitting radio signals, they record signal disturbances, which are partly due to precipitation, in order to monitor the quality of networks.

Mechanical ventilation a key indicator for Pre-Term Children's maths problems Posted: 02 Sep 2014 06:29 AM PDT Both the length of time spent in hospital after birth and the use of mechanical ventilation are key indicators of reduced mathematical ability in preterm children, researchers report. Impairments in mathematic abilities are common in very preterm children. Earlier studies of children who are born very preterm (before 32 weeks of gestational age) have shown that they have a 39.4% chance of having general mathematic impairment, compared to 14.9% of those born at term (39 to 41 weeks).

Engineers develop new sensor to detect tiny individual nanoparticles Posted: 01 Sep 2014 06:14 PM PDT Scientists have developed a new sensor that can detect and count nanoparticles, at sizes as small as 10 nanometers, one at a time. The researchers say the sensor could potentially detect much smaller particles, viruses and small molecules.

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.
