 Robotic glider harvests ocean heat for unlimited range
Woods Hole Oceanographic Institute's underwater "thermal glider" was launched in Dec. 2007, and has since traveled more than 100 miles using only the thermal stratification of the ocean layers to power its engine. Equipped with sensors and GPS, the glider could go for six months. Continue...

Gage Large Targets with Super-Wide Beam Digital Micrometer
KEYENCE adds the new LS-7070, 65mm super-wide beam LED/CCD Digital Micrometer to the LS-7000 Micrometer Series for gaging large diameter targets. The LS-7070 uses a continuous, high-intensity GaN green LED beam and telecentric optics for measurement precision. It has no moving parts and provides long-term, reliable operation. The sampling rate is 2400 samples/sec., with +/-0.2microm repeatability. The LS-7000 Series includes the LS-7030 (30mm beam width) and the Super-Fine LS-7010 (6mm beam width) models.

Researchers under attack? Report suggests way to protect them
The Society for Neuroscience believes biomedical research—and R&D in general—is leaving growing numbers of scientists open to intimidation, harassment, and even physical attack. Continue...
 Biosensor activates remotely, simplifying live cell imaging
Background light is aggravating problem for researchers examining dyed biomolecules inside living cells. To reduce ambient glow, Carnegie Mellon scientists found a way to activate fluorescence when—and only when—a marker reaches its target.

Pressure sensor designed for high-purity applications
 American Sensor Technologies' new gas and liquid stainless steel pressure sensor is the AST4900. The electropolished sensor is free of oil-fill, welds, and internal O-rings, which helps eliminate contamination risk. Continue...
Coherent introduces Mantis for ultrafast laser applications
 A short-pulse oscillator, Mantis is optimized for a single operating point, simplifying design and lowering cost. The first such system to use a 5 W green pump laser based on monolithic OPSL technology, Mantis generates 300 mW average power at 800 nm wavelength and has a bandwidth over 70 nm, compressible to under 20 femtoseconds.
