The data showed the average forces of a soccer-ball header were similar to those exerted on the head by punches from amateur boxers, according to Daniel Plant, a researcher in Imperial's department of mechanical engineering, who presented the data Friday at a helmet-safety science conference at the university.
However, largely because of the unscientific policies of the U.S. Department of Agriculture and Environmental Protection Agency, plant genetic engineering has realized only a small fraction of its potential.
