Determined to move

To move or not to move.

Semaphorins were discovered 11 years ago as molecular cues for axon guidance that are conserved from invertebrates to humans. More than 20 semaphorin genes have been identified in mammals and their protein products are now known to be involved in a range of processes from the guidance of cell migration to the regulation of the immune response, angiogenesis and cancer. Plexins, either alone or i...

Time to move on.

I am sure it is no coincidence that in the year I have turned 40 a new challenge has beckoned. In a few months I shall be heading off to train for a new career. After 20 years, six different universities and four countries it is time to venture beyond the world of higher education. I am not being terribly bold, though, quite the opposite, as I am moving into primary education. Grant application...

Time to Move On?

Cosmology and particle physics have long been dominated by theoretical paradigms: Einstein’s general theory of relativity in cosmology and the Standard Model of particle physics. The time may have come for paradigm shifts. Does cosmological inflation require a modification of Einstein’s gravity? Have experiments at the LHC discovered a new particle beyond the Standard Model? It is premature to ...

Learning to Move.

Locomotion-moving the body from place to place-is one of infants' greatest achievements. In addition to conquering gravity, infants must cope with variable and novel constraints on balance and propulsion. At the same time that they are learning to move, changes in infants' bodies, skills, and environments change the biomechanical constraints on movement. Recent work highlights both flexibility ...
