Scientists have developed a specially formulated bioink, which contains microparticles engineered for sustained delivery of insulin-like growth factor-1 (IGF-1). This delivery enhances the formation of mature skeletal muscle tissue from muscle precursor cells and facilitates their structural alignment, leading to more efficient regeneration of functional skeletal muscle tissue. This, in turn, can lead to successful therapies for people suffering from muscle loss or injury.

In response to the low-fat craze of the 1990s, many food companies removed saturated fats from their products, only to replace them with sugars to maintain their palatability. Unfortunately, the resulting products were no healthier than the originals, and the average person today consumes too much saturated fat. Now, a team of researchers has figured out how to remove some saturated fat, sugar and salt from popular American foods while maintaining their tastiness. The trick? Replacing these over-consumed nutrients with a dose of healthy herbs and spices.

The NSL (non-specific lethal) complex regulates thousands of genes in fruit flies and mammals. Silencing the NSL genes leads to the death of the organism, which gave the complex its curious name. Researchers have now discovered that the genes regulated by the NSL complex also include genes of the intraciliary transport system. This enables different cell types to form cilia on their surface, which are important for cell communication. The study shows that these genes are 'switched on' by the NSL complex, regardless of whether a particular cell has cilia or not. The researchers found that this class of cilia-associated genes is crucial for the function of podocytes. This is a highly specialized cell type of the kidney that, paradoxically, does not have cilia. These findings have important implications for ciliopathies and kidney disease.

Various medical circumstances, including heart attacks and extreme cases of COVID-19, necessitate the use of anticoagulants, medicines that prevent blood clots.
