Researchers present innovative solutions for weight management, metal protection, and pharmaceutical advancements. A dietary supplement may help control weight, fat, and diabetes, while a new coating extends the life of metals tenfold. Additionally, a gentler form of aspirin is developed using polymers.
Researchers at Virginia Tech and the University of Cadiz have developed a method to extract antioxidants from grape seeds using carbon dioxide, producing an extract with greater potency without toxic chemicals. The new process takes 25% less time and can be fully automated.
A new polymer material could revolutionize treatment of broken bones by speeding up healing and reducing the need for invasive surgery. The biodegradable material is designed to degrade like a bar of soap, allowing for a gradual transfer of load from the degrading polymer to the healing bone.
Researchers have found that electrolyzed water is a deadly combination for bacteria, but great for consumers, killing bacteria on fresh produce and reducing bacteria up to a million-fold. The acidity and oxidation-reduction properties of the water contribute to its effectiveness in sanitizing food surfaces.
New research highlights pesticides, agricultural runoff, and animal by-products as major contributors to the Chesapeake Bay's ecological issues. Scientists examine the impact of endocrine disrupters, copper-based pesticides, and atmospheric ammonia emissions from swine farms on marine life.
Researchers highlight pressing issues with museum plastics and space suit polymers, discussing efforts to halt deterioration. Experts also explore collaborations between chemists and curators to preserve historical artifacts for future generations.
Researchers have identified a new mechanism by which prions replicate their structures in yeast, suggesting a general model for understanding protein aggregation in human diseases. The finding offers potential pathways to treatment and sheds light on the novel mode of inheritance used by yeast prions.
A fiber-optic laser system, designed by Johns Hopkins University engineers, will be launched into space to gather data on air pollution and atmospheric changes. The device uses ultraviolet light to strike gas molecules, providing critical information about the health of the atmosphere.
Researchers found that high-dose immune suppression and stem-cell transplantation can lead to long-term remission in lupus patients. The treatment approach has implications for the treatment of other immune disorders, including multiple sclerosis and some types of cancers.
Researchers discover that nerve cells use chemical scissors to clip off axon guidance receptors, controlling their navigation in the nervous system. Metalloprotease inhibitors enhance netrin activity by blocking receptor cleavage.
A new polymer additive, polyisobutylene, may dramatically increase mileage and engine power with less pollution. It can produce a 10 percent increase in horsepower and a 20 percent increase in mileage.
NASA has awarded four small businesses 90-day contracts to develop concepts and requirements for a potential backup capability to provide access to the International Space Station. The study aims to enhance the station's operational flexibility by launching within a week if primary delivery methods are unavailable.
Researchers from the American Chemical Society report that untested preservation methods are causing polymers in old paintings to fall apart, leading to cracks, yellowing, and warping. Chemists are now using computer models and simulating effects of temperature, humidity, and time to prevent irreparable damage.
