Making better crops is a necessary and noble pursuit - and as the climate changes, we will need a lot more, often novel, kinds, and quickly.

Genetic engineering, astutely deployed, could help to push things along.But in these vile times the best ambitions are corrupted so that now nothing is deemed worthwhile unless it makes rich people richer and powerful governments more powerful.

The crops that find their way to the market are of the kind that only the mega-companies can engineer, while farmers, pressured by corporate-friendly governments, are obliged to grow them whether or not they are good for humanity or for the countryside.

Thus, even here, in the study of wayside weeds, we see both the power and the ambivalence of science - on the one hand vital to our survival (providing the know-how that enables us to feed ourselves), and on the other the means by which control can be exerted from above.

In general, bunion surgery consists of shaving off the bony prominence, cutting the bone to improve alignment (osteotomy) and releasing tight, contracted soft tissues to rebalance the big toe joint.

The type of surgery is dependent upon the presence of arthritis in the big toe joint, stiffness, the size of the deformity and the age of the patient.

According to George H.

Thompson, MD, professor of orthopaedics and pediatrics at Case Western Reserve University and director of pediatric orthopaedics at Rainbow Babies & Children's Hospital, both in Cleveland, the main difference between adolescent and adult bunions is "in children, most bunions are congenital in origin,...
