Navy's new 'gunk-o-lyzer'?

The LaserNet Fines instrument uses algorithms based on neural networking to analyze particulate matter, making accurate predictions with 97% accuracy. This technology has immense potential for improving the Navy's safety and readiness while reducing costs in multiple industries, including railroad, trucking, and construction.

Much ado about nanotubes

Carbon nanotubes have been shown to exhibit exceptional mechanical properties, enabling the creation of high-speed electronic devices. The breakthrough could lead to the development of hand-held DNA detectors, superfast optical detectors, and computer chip speeds faster than current Pentium processors.

Researchers say trees could affect land use, reduce skin cancer

A Purdue University method estimates how much UV-B radiation people receive under different amounts of tree cover, affecting land use and skin cancer risk. The model suggests that even partial shade provides significant protection against skin cancer, with 90% tree-canopy coverage offering the equivalent of SPF 10 sunblock.

Boneless, brainy, and ancient

Researchers have discovered that an octopus's brain operates like a general in command of troops, issuing orders to independent peripheral nervous systems. This decentralized control enables the octopus to perform complex tasks with high maneuverability and flexibility.

ThermoChemistry on a chip

Scientists at RTI in North Carolina have developed a high-efficiency thermocouple device that can make something hotter or colder over 20,000 times faster than current devices. This innovation has the potential to convert heat into electrical energy more efficiently and could lead to affordable plug-in modules for widespread use.

Brainy cameras

Researchers at the University of Illinois have developed a 'Self-Aiming Camera' that uses a simulated neural network to analyze sensory input, process it, and make decisions in real-time. The camera can learn and improve its abilities over time, enabling discrimination between targets such as humans and vehicles.

A step forward in nanotechnology

Researchers at the University of Michigan developed a new technique combining coherent nonlinear optical spectroscopy and near-field microscopy to detect quantum coherence in extended structures. This breakthrough enables sub-wavelength resolution, bringing nanotechnology closer to sophisticated devices.

New McGill researchers win recognition

New McGill researchers have been awarded $1.76 million in funding for new equipment and installations, with Quebec agreeing to match the amount. The funding will support various campus projects and research initiatives across multiple institutions affiliated with McGill.

Plankton power

Researchers at ONR and DARPA are developing OSCAR, an oceanic fuel cell that harnesses organic matter in sea sediments to generate electricity. The early versions of OSCAR have been generating about 50 milliwatts per square meter, sufficient power for small calculators.

Rock and ice linked by crushing mechanism

Two Dartmouth researchers, Erland Schulson and Carl Renshaw, propose a theory that brittle materials like rocks and ice crack in the same manner. They identify a specific type of cracking mechanism, 'comb' cracks, which leads to collapse in both ice and rock.

Researchers building a trap for chromium six

Virginia Tech researchers have created a Selective Ion Trap (SIT) device that can capture and preserve chromium six in the field, enabling faster and more accurate analysis of contaminated groundwater. The device uses a plastic membrane to trap chromium six without allowing it to transform into less reactive forms.
