There is growing scientific evidence of climate change at the Earth’s poles but also increasing worries that most people, living in more temperate latitudes, are failing to grasp the significance of these events. And it is not just scientists that are worried by this perception gap: many artists are also concerned about the apparent failure to grab public attention over these issues. A new exhi...

The British synchrotron radiation source (SRS) at Daresbury, Cheshire was a pioneering achievement when it started work in 1981. It was the first accelerator ring to be built for the main purpose of harvesting the highly focused synchrotron radiation from electrons travelling round in circles at extremely high speeds. It became an invaluable facility for high-resolution X-ray crystallography an...

correct context has taken a lot of work. Yanagida's approach to this work has been influenced by his location — starting with the choice of fission yeast. " Working on a remote island, I thought it may be better to work on a more obscure organism, " he says. And once that work was started, " we were quite happy to study these mutants in an isolated fashion. " But if the research was somewhat is...

S imple biominerals are composed of complex structures, which often have precise architectural order over several length scales. TIlis amazing architecture contributes to their superior strength and toughness, allowing them to outperform synthetic materials. Biominerals rely heavily on their biological constituents, such as biomacromolecules, for' regulation of mineralization. Pathological mine...
متن کاملRNA structure: crystal clear?
Structured RNAs play an essential role in chromosome maintenance, RNA processing, protein biosynthesis, and protein transport. To understand RNA function in these diverse biological systems, the rules for RNA folding and recognition must be learned. Recent crystal structures of hammerhead ribozymes, a group I intron domain, and RNA duplexes provide new insights into the principles of RNA foldin...
