OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
Sperm are exquisitely sensitive: they can detect a single molecule of chemoattractant that evokes an electrical signal followed by a behavioral motor response. I will outline the signalling pathway that endows sperm with such ultrasensitivity. Moreover, I will discuss how this pathway controls precise navigation in 2D and 3D gradients of chemoattractants provided by the egg. Finally, the common motifs of ultrasensitive signalling in photoreceptors and sperm will be discussed.
