See how atoms dance

see how children grow

it is necessary for community health nurses to be aware of children growth velocity as well as their height. this is a report of joan arton’s study on primary schools children. traditionally children health indicators were based on if they gain enough weight or not. although today it is proved that height is a better index for children health, but measuring height alone is not enough and growth...

Teaching bacteria how to dance

The motivational design idea for our iGEM 2006 team was to use bacteria to create swarm paintings. We designed two types of E. coli cells: senders and receivers. Stationary senders would act as attraction points; receivers would follow nutrition gradients towards the senders. In addition to the first steps of the actual in vitro designs, we developed a computer simulation of our bacterial swarm...

How we see ourselves and how we see others.

People see themselves differently from how they see others. They are immersed in their own sensations, emotions, and cognitions at the same time that their experience of others is dominated by what can be observed externally. This basic asymmetry has broad consequences. It leads people to judge themselves and their own behavior differently from how they judge others and those others' behavior. ...

Time-resolved x-ray absorption spectroscopy: Watching atoms dance

The introduction of pump-probe techniques to the field of x-ray absorption spectroscopy (XAS) has allowed the monitoring of both structural and electronic dynamics of disordered systems in the condensed phase with unprecedented accuracy, both in time and in space. We present results on the electronically excited high-spin state structure of an Fe(II) molecular species, [Fe(bpy)3] , in aqueous s...
