A group of tannins found in cranberries can transform E. coli bacteria into spheres, alter cell membranes and make it difficult for them to bind to cells. The results suggest whole cranberry products may have the greatest health effects against certain infections.
A California winemaker is using advanced spectroscopy and chromatography techniques to analyze grapes for optimal aroma, color, taste, and mouthfeel. This technology complements traditional methods like tasting grapes, allowing for more accurate predictions of when to harvest for better wine quality.
Researchers have made significant breakthroughs in improving the efficiency of solar cells, including plastic solar cells with efficiencies up to 15% and ultrathin dye-sensitized solar cells reaching 11%. Carbon nanotubes could also boost efficiency by doubling photoconversion rates.
Researchers at the University of Wisconsin-Madison have created 'conversation stoppers' that can block bacterial communication signals, offering a new approach to combat deadly bacterial infections. These small organic molecules can be combined with antibiotics to deliver a powerful one-two punch and minimize resistance development.
Researchers have developed a new proton exchange membrane (PEM) material that retains conductivity even at low humidity, overcoming a significant challenge for fuel cells. This breakthrough, achieved through self-assembling block copolymer materials, has the potential to increase the efficiency and feasibility of hydrogen-based energy ...
Researchers have identified a genetic variation that affects cancer susceptibility in people of African descent, which may influence drug metabolism and response. The p53 tumor-suppressor protein is regulated by the ASPP family of proteins, with one form linked to increased cancer risk near the equator.
Researchers have found a compound that can act like a bed of nails, fending off microbes from colonizing wound dressings and other implantable devices. Coating these devices with the compound could help prevent thousands of bacterial and yeast infections annually.
A new study published in the British Medical Journal suggests that routine use of anti-inflammatory drugs following hip replacement surgery may do more harm than good. The study found that patients taking ibuprofen for 14 days after surgery reported no significant reductions in hip pain or physical disability.
Researchers are developing a new combinatorial toolkit to evaluate hundreds of potential PEM fuel cell materials in a single experiment. The goal is to double membrane durability and cut costs in half. This project involves creating low-cost, thermally stable membranes using a 'formulation approach' that combines different polymers.
Blacksburg chemist James McGrath warns that focusing solely on functional polymers stifles basic research, which is crucial for discovery and innovation. He emphasizes the need to balance application-driven research with fundamental studies to prevent knowledge gaps.
Scientists are exploring the health benefits of functional foods, including mandarin oranges which may reduce liver cancer risk and a new type of flour with enhanced antioxidants. Researchers have also developed a 'designer soybean' that boosts calcium levels and fights osteoporosis.
Researchers at Georgia Tech are exploring the production of high-value chemicals from cellulose feedstocks, such as trees and fast-growing plants. These chemicals, worth up to $25 per pound, could help make ethanol produced by biorefineries cost competitive with traditional fossil fuels.
