Much speculation and confusion exists over climate change, and this has led a team of eminent scientists headed by Robert Watson, former White House environmental advisor and now advisor to the World Bank, to call for a balanced discussion. The group feel that information is being misused to support ideological viewpoints. They examine the scientific evidence to date and emphasise the need for closer and broader monitoring of the environment.
A series of bimetallic complexes where rhodium and ruthenium are bridged by sulfur, selenium or tellurium have been made by a team of Japanese scientists, led by Yasushi Mizobe. These are currently of interest because complexes with two different metal atoms promise different properties and improved catalytic performance. Indeed, Mizobe says they 'might provide a clue to innovate new complexes that model the enzyme hydrogenase', which produces hydrogen gas from water.
Jack Baldwin and co-workers from the Universities of Oxford and London have discovered a novel biomimetic method for the synthesis of natural products. Mimicking nature, the generation of complex structures has been achieved via a biosynthetic pathway. Natural products ( ± )-lucidene and ( ± )-alboatrin were formed using a method for o-quinone methide generation. An important development in accessing the wealth of structures available in nature, this new methodology will play a vital role in the future of drug discovery.
Molecular dynamics simulations that use 'first principles' potential energy functions (based on performing quantum chemistry calculations on-the-fly) are pushing molecular simulation into exciting new areas, but these calculations remain very computationally expensive. John Herbert and Martin Head-Gordon from the University of California, Berkeley, US, have developed a method to accelerate such calculations without the usual problem of introducing severe approximations. Herbert hopes that this work will inspire progress toward more efficient algorithms.
