Researchers have developed a fuel cell battery that runs on virtually any sugar source, offering a potential replacement for lithium ion batteries in portable electronics. The biodegradable battery has the longest-lasting and most powerful sugar-based design to date, with promising results from testing with various sugar sources.
A new study by University of Minnesota researchers found that excess nutrients and water can reduce species diversity in ecosystems, allowing a few species to dominate. The findings support the idea that plant diversity is directly related to limiting factors such as soil moisture and nutrient availability.
Researchers Twan Gielen designed a simulation programme to study the interactions between oil and water in a controlled environment. The model shows how capillary pressure affects oil and water movement, providing insights into contaminated groundwater behaviour.
The Digital Locke Project has made John Locke's first texts available online, with a digital critical edition and search functionality. The project aims to produce a definitive text of Locke's work, building on previously rediscovered manuscripts.
A study by Rutgers University and the US Department of Agriculture found that pterostilbene, a potent antioxidant in blueberries, reduced pre-cancerous lesions in rats with colon cancer by 57%. The compound also inhibited inflammation and cell proliferation.
Researchers at the University of British Columbia have identified a peptide that can fight infection by boosting the body's own immunity, reducing bacteria counts and mortality in animal models. The innate defense regulator peptide (IDR-1) may be useful as a supplement to antibiotics in combating common hospital infections.
Researchers tested a new cholesterol treatment LY518674 (LY5) in two studies, but found it showed no benefits compared to fenofibrate. Both drugs raised safety concerns, particularly for kidney function.
Scientists have developed a pair of molecular-scale scissors that can be manipulated by light, allowing for precise control over proteins and biological molecules. The technology has the potential to revolutionize gene manipulation and drug delivery, with practical applications still several years away.
