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.

From rockets to hot rods to....

Advanced Ceramics Research (ACR) Inc., a Naval research-funded company, has partnered with the Tohono O'odham Native American Nation to establish a high-tech manufacturing facility. The joint venture aims to produce eco-friendly composite products, including Aquacore, a water-soluble polymer matrix composite.

Listening for an ocean

Researchers suggest deploying vibration-sensitive acoustic sensors on Europa's surface to probe the interior structure and search for signs of life. Massive ice fractures generate unusual cracking sounds that could penetrate the thick ice layer and propagate through the underlying ocean.

U.S. Department of Defense awards University of South Florida $4 milliion to prepare state's public health system for bioterrorism threat

The US Department of Defense has awarded the University of South Florida $4 million to develop a statewide public health system capable of responding to bioterrorism threats. The project aims to create a surveillance system that can detect and track both naturally occurring infectious diseases and potential bioterrorist attacks.

Smallest silicon particles light way for new sensors, materials

Purdue University researchers have developed a method to stabilize the surface of porous silicon, enabling its use in creating new types of drug-delivery systems and biological sensors. By functionalizing the surface with specific chemicals, scientists can tailor the material's response to specific chemical environments or cues.

Researchers examine the use of antiretroviral therapy among injection drug users with HIV infection: Study suggests addiction treatment and health care contribute to HAART enrollment

A study by Johns Hopkins Bloomberg School of Public Health found that nearly one third of eligible injection drug users never received antiretroviral treatment. Methadone addiction treatment, health insurance, and regular access to care were associated with increased HAART use among men.

Treating frail and elderly patients.

The University of Michigan School of Nursing is introducing a new concentration in care for frail and elderly patients, addressing the complex needs of this vulnerable population. Students will explore the holistic effects of frailty on physical, psychological, and social aspects of quality of life.

UCSF study finds shortage of California dentists in rural, poor, minority communities

A recent study by UCSF researchers reveals a significant shortage of dentists in California's rural and underserved communities. The study found that two-thirds of communities without dentists are rural and at least 20% of California communities face a dentist shortage, exacerbating oral health disparities.

Monarch butterflies, corn pollen coexist in cornfields

Researchers found that monarch larvae are more likely to be exposed to toxic corn pollen when pollen is shed during peak larval activity. In Ontario, 62% of larvae were exposed to toxic pollen, while in Iowa, the figure was 15%. The study suggests that agricultural habitats like cornfields are crucial for monarchs.
