Washington Independent Examines U.S. Food Aid
The Washington Independent examines a recent Government Accountability Office (GAO) report, which found that a federal law requiring most international food aid to come from U.S. farmers could be "hobbling efforts to feed the world"s hungry." Currently, Food for Peace - the nation"s largest food aid program - "requires that the crops be purchased from U.S. growers, processed through U.S. companies, and shipped using U.S.-flagged vessels," according to the article.

Long-Term Medtronic Device Registry First To Show How Implantable Heart Devices Work In Real-World Clinical Practice
The first results from the Medtronic Inc., (NYSE: MDT) OMNI Study were released at Heart Rhythm 2009, the annual congress of the Heart Rhythm Society, revealing that one out of six patients with implantable cardioverter-defibrillator (ICD) or cardiac resynchronization therapy-defibrillators (CRT-Ds) to prevent sudden cardiac arrest (SCA), received potentially life-saving medical therapy - either in the form of anti-tachycardia pacing (ATP) or a shock for dangerously fast heart rhythms - within a period of two years following their implant. Further, the study showed that patients received therapy at similar rates, regardless of whether they meet current medical society guidelines.

Real-Time Observation Of Queensland's Drinking Water

CSIRO and a local water authority in Queensland, SEQWater, have joined forces to monitor the Lake Wivenhoe catchment, which spans an area about the size of the city of Brisbane, and supplies water to the region"s 1.5 million residents. Approximately 120 nodes, using CSIRO"s FLECK™ smart wireless sensor network technology, are monitoring environmental conditions on Lake Wivenhoe and in the surrounding catchment. CSIRO Senior Research Scientist, Dr Matthew Dunbabin said it is hoped that these sensors can provide the platform for the next generation of water quality monitoring systems. "This is about real time data collection from the storage to the shore with a level of speed and detail not seen before," Dr Dunbabin said. The sensor nodes operate in a meshed network, which means they record environmental variables and cooperate with each other to set up an ad hoc network to wirelessly transfer data. "This gives us the capacity to monitor "events" in real-time, such as high rainfall, droughts or contaminants entering the waterway," Dr Dunbabin said. "If the network detects an "event", it can autonomously advise the boat to sample in more detail." Seqwater principal scientist, Associate Professor James Udy said the network is a cost-effective way of integrating different measures such as water quality, event flows, weather and pasture conditions, as well as cow movement. Of the 120 nodes, 45 are floating and measure water temperature through the water column, while another 70 are land-based and spread across the catchment. An autonomous solar-powered catamaran travels between the floating nodes gathering data. Developed by CSIRO, this is manually controlled through a PDA, web interface or web-enabled mobile phones.
