Bio-hydrogen: microbes have their own agenda.
The international hydrogenase community stages a meeting every 3-4 years, and this time it was held in the University of Reading. Each congress has revealed new aspects of the complex nature of hydrogenases: their structure, molecular mechanisms and biosynthesis are all yielding up their secrets.

متن کاملWhere have eye been? Observers can recognise their own fixations.
We are often not explicitly aware of the location of our spatial attention, despite its influence on our perception and cognition. During a picture memory task, we asked whether people could later recognise their eye fixations in a two-alternative test. In three separate experiments, participants performed above chance when discriminating their own fixation patterns from random locations or loc...
متن کاملNociceptive primary afferents: they have a mind of their own.
Nociceptive primary afferents have three surprising properties: they are highly complex in their expression of neurotransmitters and receptors and most probably participate in autocrine and paracrine interactions; they are capable of exerting tonic and activity-dependent inhibitory control over incoming nociceptive input; they can generate signals in the form of dorsal root reflexes that are tr...

متن کاملLife or death: developing cortical interneurons make their own decision.
During nervous system development, programmed cell death is considered as an essential adaptive process. The mechanism by which the number of mature neurons is determined in the central nervous system is not well understood. In a recent Nature paper, Southwell et al (2012) demonstrate that cortical GABAergic interneuron cell death is intrinsically determined without the need to compete for extr...
