A simple blood test identified patients who benefited markedly from glycoprotein IIb/IIIa platelet inhibitor drugs, showing a 50% improvement in risk of death and second heart attack. Patients with high troponin T levels were found to be at increased risk and benefit most from these drugs.
Dr. Joseph Testa receives award for his research on mesothelioma, a cancer associated with asbestos exposure. His work aims to understand the genetic alterations that occur in affected cells and potentially develop new treatments.
Researchers aim to expand traditional testing to include creative and practical abilities, enabling students to capitalize on natural strengths and achieve higher levels of success. The new grant will test triarchic instruction in rural, suburban, and urban settings across the country.
According to Bruce W. Tuckman, frequent quizzes can significantly improve students' grades by reducing procrastination and increasing motivation. Students with low GPAs who received weekly quizzes outperformed their peers by an average of 4-24% on midterm and final exam grades.
Researchers use a massive centrifuge to simulate earthen dam failures and study the effects of sinkholes on full-sized dams. The 400g-ton machine, built in 1988, can spin loads of up to 2 tons at 200 times gravity.
The American Red Cross has developed a new genetic test, nucleic acid testing (NAT), to detect viruses such as HIV and Hepatitis C Virus (HCV) in blood donations. This technology can identify infectious agents earlier than current screening tests, reducing the risk of disease transmission through blood products.
A Mayo Clinic study published in Annals of Emergency Medicine found that electron-beam computed tomography (EBCT) is an efficient and cost-effective screening tool for patients with chest pain. The test can detect coronary artery calcification, allowing doctors to safely send patients home without further observation.
The new high-strength, ultra-thin steels are being tested for endurance on life-size testing rigs to simulate 40,000km of rocky road driving. The materials range in thickness from 0.7 to 2 mm and have improved fatigue properties.
A Massachusetts Institute of Technology professor has developed a quick and easy test that can analyze thin films used in microelectronics components using an optical method. The device, which uses short laser pulses to generate ultrasonic waves, can measure film thickness to within one layer of atoms in one second.
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.
A UB researcher is conducting a four-year study on how temperature, humidity, and ultraviolet light impact the transport of persistent organic pollutants through the atmosphere. The project aims to understand how plants contribute to the global distribution of toxic chemicals.
The University of Illinois will participate in a $250 million, 10-year program to develop advanced computational systems for simulating solid-propellant rockets. The center will focus on detailed whole-system simulations, benefiting both basic scientific research and aerospace applications.
Researchers at Michigan Technological University have developed a method to measure dynamic indentation hardness in materials, which could render traditional tests obsolete. The new device can achieve results in under 200 microseconds, reducing the need for costly and time-consuming tests.
The University of Cincinnati engineers have created a unique high-performance concrete (HPC) mix that significantly strengthens conventional concrete. Tests show the HPC can last up to 80 years without major maintenance due to its denser material and resistance to freeze-thaw cycles.
A survey of psychologists found they use more test results and review more materials in custody evaluations. Attitudes also shift towards greater preference for joint custody and less reliance on single variables.
The Oak Ridge National Laboratory has developed a new wall testing and rating procedure to determine the thermal performance of entire walls, rather than just insulation. This approach accounts for increased heat leakages in corners, doors, windows, and studs, providing more accurate measurements of building energy performance.
A new blood test called troponin T has been shown to be a powerful indicator of how injured a heart is, especially in patients with no clear signs of trouble. The study found that patients with high troponin T levels are more likely to die within a month, and the test may save thousands of lives annually.
The new test developed by Prof. Roald Nezlin of the Weizmann Institute solves a problem with standard tests by measuring the quantity of DNA in harmful complexes, indicating effective treatment. This approach could also be used to measure antibody complexes involved in other autoimmune diseases.
