The draft human genome sequence (about 3 billion base pairs) was completed in 2001. Humans have fewer protein-coding genes than expected, and most of these are highly conserved among animals. Humans and other complex organisms produce massive amounts of non-coding RNAs, which may form another level of genetic output that controls differentiation and development. Aside from classical monogenic diseases and other differences caused by mutations and polymorphisms in protein-coding genes, much of the variation between individuals, including that which may affect our predispositions to common diseases, is probably due to differences in the non-coding regions of the genome (ie, the control architecture of the system). Within 10 years we can expect to see: increased penetration of DNA diagnostic tests to assess risk of disease, to diagnose pathogens, to determine the best treatment regimens, and for individual identification; a range of new pharmaceuticals as well as new gene and cell therapies to repair damage, to optimise health and to minimise future disease risk; and medicine become increasingly personalised, with the knowledge of individual genetic make-up and lifestyle influences.

Juniperus ashei pollen, a significant aeroallergen, has been recorded during December and January in Tulsa, Oklahoma, over the past 20 years. The nearest upwind source for this pollen is populations growing in southern Oklahoma and central Texas, at distances of 200 km and 600 km respectively. Long-distance dispersal of J. ashei pollen into the Tulsa area shows a strong correlation with the trajectories of wind blowing across southern populations before traveling north towards eastern Oklahoma. The strong tie between climatic conditions and the occurrence of this aeroallergen within the Tulsa, Oklahoma, atmosphere provided a unique opportunity to forecast the dispersal, entrainment, and downwind deposition of this significant aeroallergen. Forecasts of long-distance J. ashei pollen dispersal began during the winter of 1998/1999. Each forecast uses defined climatic parameters to signal pollination at each source site. Coupled to these estimates of pollen release, forecast weather conditions and modeled wind trajectories are used to determine the threat of dispersal to downwind communities. The accuracy of these forecasts was determined by comparing the forecast "threat" to aerobiological records for the same period collected in the "Tulsa region". Analysis of the two seasons revealed only a single occurrence of "high" or "very high" pollen concentrations in Tulsa not directly linked to "moderate" or "severe" forecast threats from the southern source areas.
