‘Fire-free’ survival strategies for the early occupants of north-west Europe
In Europe, archaeological traces of fire become more frequent between 300,000 and 400,000 years ago; but could the earliest occupants have survived without fire for at least half a million years before this? How could the early occupants of Europe have kept warm and processed meat without fire?

Triple Bioorthogonal Ligation Strategy for Simultaneous Labeling of Multiple Enzymatic Activities
Three at the same time: a ligation strategy combining tetrazine–norbornene cycloaddition, Staudinger–Bertozzi ligation, and copper(I)-catalyzed click reaction was used to label the three catalytic activities of the proteasome simultaneously in a single experiment. The orthogonality of the three ligation…

Why are plants not black?
All kinds of reasons have been put forward for why plants apparently fail to make maximum use of the available light. None of these reasons can explain why after two billion years of evolution they are not black, like industrial photovoltaic solar cells. Are we missing something?

What plant genes can teach us
Just like us, plants also produce growth hormones, and they also go through an ageing process. The study of the genes and mechanisms behind these processes is useful not only for crop breeding and agriculture, but also for medical research. That is the view held by Professor of Plant Developmental Genetics…

Improved Strategies for Distance Based Clustering of Objects on Subsets of Attributes in High-Dimensional Data
This monograph focuses on clustering of objects in high-dimensional data, given the restriction that the objects do not cluster on all the attributes, not even on a single subset of attributes, but often on different subsets of attributes in the data.
