Nature CheapPromes cell biology


Introductionpowerpoint is a joy to use click a few highly intuitive buttons to animate your favourite model and the results seem the work of professionals with years of film school behind them.Customize your graphics to rival the finest glossy magazines.But does a visually striking presentation really make your research more accessible or memorable?Do bouncing phosphates really explain a kinase reaction better?We would argue that overbearing graphics tend to distract the audience from the science.

The mobile ringtone craze seems to have been replaced by an addiction to fancy slide transitions which seem irresistible to the multiconferencehopping principal investigator stuck in an airport lounge waiting for an indeterminably delayed flight.The final frontier in the multimedia circus of some presentations seems to be audio it is just a matter of time before the first experiment is enhanced with the opening bars of beethoven's fifth.

This journal will certainly not bemoan the advent of the digital age(Although powerpoint lacks the romanticism of a mildewed first few slides to say 'this is where it all started').Neither does it intend to undervalue a bit of light entertainment to keep the audience's attention on the last day of an overloaded conference.More importantly, for the cell biologist, modern presentation technology has of course been tremendously beneficial;In particular the realtime presentation of sizeable movies and the spatial navigation of threedimensional microscopy images or protein structures permit datarich and accessible presentations.

However, graphics tools ought to be used only when necessary.It is worth reflecting on the frustrating experience of watching a hollywood movie so overloaded with special effects that it leaves the viewer drained from sensory overload but intellectually and emotionally unsatisfied.Less is more:After a day cheap evening dresses online of backtoback talks, nothing is more refreshing than a visually clear, logically constructed and well articulated presentation.

A case in point was a recent involuntary but highly effective experiment by daniel a.Haber of the massachusetts general hospital cancer center, who gave a presentation on the last day of the cnio/nature conference oncogenes:The next 25 years' last month in madrid.Daniel decided to travel light and relied on the pen drive in his righthand jacket pocket for his slides.Unfortunately it was only during the pretalk coffee break that he noticed his pen drive was not in any of his pockets.Utterly unperturbed, he presented an oratory masterpiece apparently covering all the data on his slides(Which he occasionally tried to visualize with a laser pointer on the blank screen).Remarkably, he stayed precisely on time(One wonders if that would have been achievable with slides)And his findings were accessibly presented.Despite the late hour, the audience was well engaged and focused on the speaker the house lights were up and the speaker faced his audience.Most would agree that this was one of the most memorable talks in an altogether excellent conference.

The physical sciences which of course require the presentation of highly complex concepts have retained their traditional use of minimal visual aids.Cell biology is an observationbased discipline, and this may explain the field's affinity for visual support.Nevertheless, some 'do without' by choice:Sydney brenner has famously done away with slides altogether and certainly gives striking presentations.We would not necessarily advocate such a dramatic move unless of course you can marshal daniel haber's undeniable oratory skills.However, it is worth taking a lesson from this experiment:Focus audience attention on cheap wedding dresses australia the speaker, do not read off the screen and reserve slides to present key data and to summarize a complex body of work.Why not introduce the talk without slides?
