A study by The Hershey Company reveals resveratrol, a compound found in red wine, is also present in cocoa and dark chocolate products. These foods contain significant levels of resveratrol, an antioxidant with potential health benefits.
A new study published in Journal of Agricultural and Food Chemistry emphasizes the high antioxidant content of natural cocoa powder. Natural cocoa powders contain an average of 34.6 mg of flavanols per gram, making them one of the richest sources of these beneficial antioxidants.
A new test can detect gunshot residue on a single speck of gunpowder smaller than the width of a human hair, boosting accuracy and reducing false positives. The test uses solid phase micro-extraction combined with gas chromatography to identify chemical compounds present in the powder.
Researchers have designed a high-performance permanent magnet alloy that operates with good magnetic strength at 200 degrees Celsius. The new alloy, which replaces pure neodymium with a mixed rare earth, has a lower temperature coefficient, making it suitable for electric drive motors in the automotive industry.
Scientists have successfully determined the structure of microcrystal grains using a new set-up at the European Synchrotron Radiation Facility. This breakthrough allows researchers to study crystalline structures previously too small to analyze, enabling potential advances in fields like chemistry, physics, and biology.
Researchers at Texas A&M University are developing an aloe vera-based nosespray vaccine that has shown promising results in animal trials. The vaccine uses a gel-like substance to cling to the inside of the nose, allowing it to stay longer and work more effectively than traditional liquid sprays.
A new study found that cherry-enriched diets lowered blood cholesterol, insulin levels, and other factors linked to metabolic syndrome. Researchers say the findings are encouraging and will lead to further clinical studies in humans.
Researchers at MIT found that the nanostructure of cement is responsible for its strength and durability, rather than the material itself. By understanding this organization, they aim to develop a new type of concrete with reduced carbon dioxide emissions.
A University of Illinois study reveals that combining tomatoes and broccoli in the diet can effectively reduce prostate tumors. The study found that eating both foods together produces an additive effect, with tumor cells proliferating more slowly.
The researchers found that the dust grains have a porosity of over 90%, similar to powder snow, allowing them to measure the agglomeration process of interstellar grains. This discovery provides valuable insights into the early days of our planetary system and how dust grains grow from interstellar sizes to macroscopic objects.
A new national standard for collecting suspicious powders has been developed by AOAC International, providing a uniform procedure for emergency responders and federal agencies. The standard addresses the need for safe handling, transportation, and analysis of samples from visible powders suspected to be biological threat agents.
Researchers at Iowa State University are testing combustion for NASA using a new technology called electric particulate suspension. The goal is to understand how powders burn and ignite under various conditions, which could lead to improved fire safety and the development of a new safety standard.
The Penn State team has successfully developed a method to calculate optimal proportions of niobium powder to binder and temperature for sintering, opening doors to injection-molded niobium parts. The approach can be applied to other materials with irregularly-shaped particles, expanding its potential applications.
The Oak Ridge Associated Universities funds research to develop conductive ceramic materials. Lu, a Virginia Tech graduate student, aims to create advanced ceramic materials by incorporating carbon nanotubes. She has achieved 40% density, significantly improving the material's strength and conductivity.
Researchers found that cranberry juice powder relaxes and opens blood vessels in genetically susceptible pigs, improving vascular function. The next step is to identify the specific components of cranberries responsible for this effect and develop a palatable way to consume them.
A recent study suggests that lycopene's anti-cancer effect is enhanced by other compounds in tomatoes, such as phytochemicals. Whole tomato consumption was found to offer a lower risk of prostate cancer death compared to dietary supplements.
A study published in the Journal of the National Cancer Institute found that rats fed whole tomato powder had a 26% lower risk of prostate cancer death compared to those on control diets. The researchers suggest that whole tomato products and energy balance may offer independent benefits against prostate cancer.
Researchers at NIST created improved phantom materials that can mimic blood, bone, fat, and skin using carbon black powder. These polymers have low-frequency electrical properties and can be formed in various shapes and sizes.
Scientists at Penn State University have created a novel method for synthesizing cage-like silica structures by combining different templates and heating them in a microwave oven. This innovative approach produces larger particles with improved stability and reduced synthesis time compared to previous methods.
A study found that consuming cocoa and dark chocolate slowed LDL oxidation by 8% and boosted total antioxidant capacity. However, experts stress the importance of a balanced diet that includes a variety of whole foods to support overall cardiovascular health.
Researchers found that consuming flavonoid-rich chocolate can increase HDL cholesterol and slow down LDL oxidation. This effect may contribute to a reduced risk of cardiovascular disease.
A team of Penn State researchers successfully used microwave sintering to produce machine components with improved mechanical properties in just 10-30 minutes, compared to traditional sintering methods which take long periods of time and large amounts of energy.
A two-year study of 350 pregnant women in Tanzania is being conducted to evaluate the effectiveness of a simple fortified drink in improving iron and general nutritional status. The drink, made with 11 vitamins and minerals, has shown promising results in improving anemia and other nutritional deficiencies in Tanzanian children.
Researchers at Sandia National Laboratories have developed three robotic systems to streamline the dismantlement of nuclear weapons, including AGGDIS and WALS. These systems can handle delicate operations faster and more accurately than humans, reducing radiation exposure and increasing efficiency.
