Researchers have achieved a record light conversion efficiency of 8.2% in solvent-free dye-sensitized solar cells, paving the way for large-scale outdoor applications. The development of an electrolyte mixture made from three solid salts replaces volatile organic solvents, making it possible to produce lightweight and inexpensive flexi...
An international team of researchers has identified 21 new genetic risk factors for Crohn's disease, building on earlier studies that linked the disorder to disruptions in autophagy and immune system response. The findings, published in Nature Genetics, may lead to novel therapies and prevention strategies.
Researchers at UIC have identified a novel function for an enzyme involved in tissue injury in acute respiratory distress syndrome (ARDS). The finding offers new therapeutic targets for lung inflammation and injury prevention.
A longitudinal study found that only 42% of boys and 11% of girls meet the recommended weekly physical activity levels. While children who met the guidelines showed progressive improvement in predictive health indicators, those who did not showed deterioration. The authors suggest re-evaluating the guideline measures to better encourag...
Rates of sexually transmitted infections (STIs) have more than doubled among people aged 45 and older between 1996 and 2003. Genital warts and herpes were the most common STIs diagnosed in this age group, with rates highest among men aged 55-60 plus and women aged 45-54.
Researchers discovered that using mental strategies can decrease arousal linked to the anticipation of a potential reward. The study sheds light on how emotion regulation affects decision-making and may help control positive emotions and eventual urges, such as drug cravings.
Scientists have found that Deformed Wing Virus (DWV) does not replicate in Varroa mites, highlighting the need for further investigation into its transmission. Research suggests that the virus is transmitted to bees when the mite bites and picks up infected bees' saliva or gut contents.
A study published in Nature Genetics has identified over 30 genetic regions associated with Crohn's disease, revealing surprising links between the condition and other common diseases like asthma. The research also highlights the complexity of the disease, suggesting hundreds of genes may be involved.
Smoke-free policies are reducing heart disease related to smoke exposure, prevalence of smoking in adults, and second-hand smoke exposure. These policies also increase smoke-free environments and have benefits for non-smokers.
Researchers at the Salk Institute have made a groundbreaking discovery by reprogramming adult brain stem cells into support cells in their natural environment. This achievement opens up new avenues for treating neurological diseases such as multiple sclerosis, stroke, and epilepsy.
A large cohort study of over 87,000 women found that heavy birthweight female babies are twice as likely to develop rheumatoid arthritis in adulthood. The findings support the fetal origin of disease theory, suggesting that certain conditions and diseases may be programmed by factors during pregnancy.
