The conflict in Iraq has divided world opinion, driving deep wedges even between longstanding allies. In its wake, rebuilding international collaboration will be vital — and in that task, scientists should take a lead.
Joan — formerly Jonathan — Roughgarden rejects established evolutionary ideas about gender roles and sexuality. Everyone wants to discuss the parallels with her personal experience. But the science speaks for itself, she tells Virginia Gewin.
Plans for a vaccine for Alzheimer's disease were derailed last year when clinical trials revealed serious side-effects. But as Erika Check finds out, this approach could be about to get back on track.
By constructing evolutionary trees of genes, researchers have detected three big genome duplications in the history of the plant Arabidopsis, and one in the recent history of yeast.
It isn't easy to create a semblance of order in interconnected dynamical systems. But a mathematical tool could be the means to synchronize systems more effectively — and keep chaos at bay.
The fate of neurons in the developing brain and in Alzheimer's disease may lie with a four-protein complex that regulates the cleavage of two molecules spanning the cell membrane. The role of each protein is now being unveiled.
Two groups have created logic gates using pairs of trapped ions. As components of a quantum computer, these gates have the potential to form part of a scaled-up, workable system.
Fossils of bushbabies and lorises reported from deposits of the Fayum Depression in Egypt extend the known record for this group of primates from 20 million years to approximately 40 million years ago.
Quasi-particles, an ingenious dodge used to simplify calculations on vast systems of interacting particles, seem to account for the fractional quantum Hall effect. But do we now need a further generation of quasi-particles?
