Voters in California will decide next month on an initiative that would assign $3 billion to research on human embryonic stem cells. But the proposal is less of an unalloyed blessing than it seems.
The next generation of Antarctic research stations is now being designed and built. Quirin Schiermeier reveals the problems that architects, engineers and inhabitants must overcome in the Pole's unforgiving conditions.
With the rules of the game changing before every season, Formula 1 engineers often have a matter of weeks to redesign their car before it is tested on the track. Karl Ziemelis and Charles Wenz join the race to the start line.
The results of an innovative way of tracing the life and death of neurons in culture favour one side of a debate about the protein accumulations associated with certain disorders of the nervous system.
In neutron-rich nuclei, weakly bound neutrons form a halo surrounding a compact core. Unexpectedly, it seems that this halo does not improve the chances of the nucleus fusing with another nucleus.
Fruitflies can time their morning and evening activities to the day–night cycle. The basic circadian oscillatory mechanism is intracellular, but networks of cells, now being identified, are what make a working clock.
Information processing in the brain requires the neurotransmitter glutamate. Hence the importance of today's publication of the structure of an archaeal relative of the transporter controlling glutamate's levels.
If you read these words from Marvin Minsky: "minds are what brains do" and "doing means changing", your brain's fine structure may be durably altered. Such is neuronal plasticity, a concept that has found a home in many areas of neuroscience, from brain repair to learning and memory. But plasticity is not only a reaction to change; it is also a source of change. This Insight considers plasticity as the critical engine of neuronal computation.
