Researchers at Idaho National Laboratory and Miragen are developing a technique that uses antibodies to identify individuals, offering a potential alternative to DNA testing. The Antibody Profile Assay can distinguish between identical twins and provide results in just two hours.
Researchers are developing a non-destructive testing technique that can detect cracks in materials and welds under extreme conditions. This technology is being adapted for use in space to test the International Space Station and other structures, reducing the need for costly repairs.
Researchers at Georgia Tech have developed a high-performance material to repair bridges, reducing costs and increasing durability. The material has been tested on several bridges, showing promise in extending lifespan by 30-40%.
A study of 13,204 female military recruits found a 9.2% overall prevalence of chlamydial infection, with peak rates among 17-year-olds. Screening programs based on age could identify 95.3% of infected women using DNA amplification tests like LCR assays.
A Northwestern University Medical School study found that low literacy levels were a significant predictor of having incurable prostate cancer among low-income white and black men. Poor reading skills were more prevalent among black men with advanced cancers, suggesting low literacy as a key factor in the disparity.
Researchers developed tests to determine how well bipolar electronics, commonly used in satellites, can survive long-term radiation exposure. The tests, led by Sandia National Laboratories, predict a 10-year response in just a few weeks and have already benefited systems, preventing potential failures.
Researchers from Lawrence Berkeley National Laboratory tested various sealing materials, including clear plastic tape, foil-backed tape, mastic, and injected aerosol sealant. Only duct tape failed the tests, while others formed good seals for extended periods.
A partnership between Colorado State University and Michigan has made canola-based motor oil available to consumers, offering a cleaner alternative to petroleum-based oils. The oil reduces vehicle emissions by 30 percent and produces no hazardous waste.
Scientists have sequenced the complete genome of Treponema pallidum, the syphilis bacterium, providing critical information for developing diagnostic tests, treatments, and vaccines. The genetic blueprint reveals targets for new antibiotics and surface proteins that could stimulate an immune response in experimental vaccines.
Standardized tests differ significantly in content and format, making it challenging to compare scores across unrelated tests. The National Research Council committee found that an equivalency scale is not feasible due to these differences.
A new liquid crystal assay developed at the University of California, Davis, can detect target molecules in test samples using minimal supplies and no electricity. The assay uses a microscopic landscape of hills and valleys to bend light and create colorful patterns, allowing for quick and easy analysis.
Chlamydial infection is a leading sexually transmitted disease in the US, causing infertility and severe complications. Age-based screening has been shown to be cost-effective in identifying infected women without symptoms, preventing sequelae and saving lives.
A new blood test that measures troponin T, a protein released by dying heart muscle during heart attacks, can identify high-risk patients and predict long-term risk. The test has been shown to detect cardiac events or death within 30 days with high accuracy.
