Over time, a loved one's gravestone can gather layers of dirt and debris and become susceptible to the elements. Here's how you clean it.
A team of researchers at IOCB Prague led by Prof. Michal Hocek has developed a novel method for preparing ribonucleic acid (RNA) containing modified bases. Innovative use of engineered DNA polymerases, enzymes commonly used for the synthesis of DNA, led to the development of a general method for the synthesis of RNA modified only at selected sites or even RNA containing various modifications at all nucleotide building blocks.
Ion exchange is a powerful technique for converting one material to another when synthesizing new products. In this process, scientists know what reactants lead to what products, but how the process works—the exact pathway of how one material can be converted to another—has remained elusive.
As the lunar exploration mission evolves from exploration to construction and utilization, in situ lunar construction becomes an imperative requirement. The key is regolith solidification and formation, aiming to maximize local resource utilization while minimizing transportation and maintenance costs.
In the field of organic chemistry, scientists are always looking out for new types of reactions to unlock synthesis routes for challenging compounds. Most of the progress that we have witnessed in pharmaceutics and agrochemicals over the past few decades can be traced back to the discovery of novel practical reaction pathways. Such pathways often involve the selective replacement of a functional group with another, the formation of aromatic rings, or the strategic cleaving of parts of a...
Recently published research results enable preparative access to novel substances that carry a modification of a structural motif frequently found in pharmaceuticals.
If finalized, the proposed rule would apply to any future fission reactor application and could reduce environmental review costs by up to 45%, Nuclear Regulatory Commission staff found.
Researchers led by Satoshi Kamiguchi at the RIKEN Center for Sustainable Resource Science (CSRS) in Japan have discovered a greener way to produce ammonia, an essential compound used in fertilizers.
Thermal barrier coatings (TBCs) are widely used in gas turbine engines to obtain elevated working temperatures and improve engine efficiency. The phase transition of the ceramic layer is accompanied by a large volume difference, causing the concentration of thermal stress, eventually leading the TBCs to fall off and fail. Therefore, it is necessary to quantitatively evaluate the magnitude and distribution of thermal stress induced by phase transition in the ceramic layer.

Nothing says ‘cosy pub’ like an old labrador dozing beneath a wooden table, but when that dog is exceptionally flatulent, it certainly does change the atmosphere. Even little dogs can be problematic. A few weeks ago a friend and I met at just such a warm and welcoming hostelry. While we perused the menu, a lady appeared with one of those handbag sized dogs, which she popped down. It promptly made for the very centre of the room and I think you can guess what happened next. It may have been tiny,...
