Nanotechnologists are increasingly concerned about the lurid descriptions of the dangers of their work being promulgated by environmental campaigners. But the field's proponents aren't helping their cause by making exaggerated claims.
Nanotechnology is set to be the next campaign focus for environmental groups. Can scientists avoid the mistakes made over genetically modified food, and secure public trust for their research? Geoff Brumfiel investigates.
When considering the location of human cognitive functions, neuroscientists still refer to imprecise anatomical maps drawn up almost a century ago. But not for much longer, says Alison Abbott.
In their study of predator–prey cycles, investigators have assumed that they do not need to worry about evolution. The discovery of population cycles driven by evolutionary factors will change that view.
Particle accelerators tend to be large and expensive. But an alternative technology, which could result in more compact, cheaper machines, is proving its viability for the acceleration of subatomic particles.
Understanding how we grow old is a long-sought goal. A new large-scale study of gene expression in worms allows us to glimpse the complex biochemistry of lifespan.
A new study of past variations in El Niño behaviour provides a much improved record from pre-instrumental times. It will be a valuable resource for testing the models used in climate prediction.
The uncertainty principle limits the accuracy of measurement at the quantum level. A device sensitive to subatomic-scale displacement has come close to revealing that principle in action in the macroscopic world.
Genes expressed in the vertebrate brain and spinal cord show up in the surface nerve net of a closely related group of invertebrates. Could this mean that brains started out on the body surface?
