The idea is that the mind is changing the probability density function. That is, say you flip a coin 100 times. You have pretty much a binomial probability distribution. That is, you have the largest chance of getting 50 heads and 50 tails, but even 40 and 60 would not be remarkable. Now, the idea is that with the mind, you could change the probability distribution to having 55/45 be the most likely result. It's not changing any particular event, which is therefore still random, but does change the overall statistics.
The study refered to involves a black box spitting out random numbers, 1s and 0s. When a group of people focus on changing the numbers, there appear to be more of one number than the other compared to when nobody is thinking about it. These "eggs" as they are called similarly changed their patterns just before 9/11 and other major events. Of course, all one can conclude is that something somewhere did something to the eggs, but we can't tell what. It's very strange, but there are serious scientific investigations into the matter.
