The rich world's corridors of power echo with talk about the new 'war on terrorism'. Meanwhile, most developing countries are losing another war that has already inflicted millions of casualties.
Take a lab full of test tubes, flasks and stirrers, and cram it onto a silicon chip — that's the dream of microfluidics researchers. And as Jonathan Knight finds out, this vision is becoming a practical reality.
Is it possible to adopt a more rigorous approach to the communication of scientific uncertainty? Jim Giles talks to the climatologists whose pursuit of this goal has seen them dubbed the 'uncertainty cops'.
The use of immunological diversity to generate selective catalysts has come full circle, to the realization that antibodies have an intrinsic catalytic ability to destroy antigens.
A well-preserved crater has been identified deep beneath the bed of the North Sea. It may well have been produced by the impact of an extraterrestrial body some 60 million years ago.
Although we understand how fearful memories are stored in the brain, how they are extinguished remains a mystery. The answers may lie with the cannabinoid compounds our bodies produce.
Calculating the age of the Earth's solid inner core has proved to be a tricky business. But the suggestion that there is more potassium in the core than had been thought could help to reconcile differing estimates.
Zeolites are porous structures that can be fabricated around a template for a variety of uses. Wood might seem an unlikely choice for a template, but in fact the zeolites formed reproduce the cellular structure of the wood in exquisite detail.
What is the developmental mechanism that makes our upper arms different from our forearms or fingers? Two new papers challenge an influential and popular model, and propose an alternative view.
Magnetic-memory devices rely on fast switching of the magnetization vector in a material to store data. The speed of such devices could be increased by adding a magnetic-pulse-shaping technique.
Various molecular actors play out the scene in which a cell exits mitosis — nuclear division — before entering the next cell cycle. One of them, the protein Clb2, steps back into the spotlight. Another, Clb5, bows out.
