James Cahill of the University of Alberta, and Jeff Castelli and Brenda Casper of the University of Pennsylvania were conducting field studies of plants in an abandoned hayfield and along a forest floor when they noticed that plants they had marked for study were experiencing extremely high rates of attack by insects. Plants that they had not disturbed were faring much better.
Could it be that they, the detached and impartial scientific observers, were making a difference in the plants' environment that affected their survival?

Sip your coffee slowly and it will last longer, one cup of stimulation for twice the length of time. Keep it warm in a thermos and you save on microwaves. Re-use your coffee grounds and you'll save nearly 30 pounds of coffee, or $200, by year's end.
Here it goes again, that compulsion to count and figure and cut and scrimp. Like some actuary, I'm compelled to calculate the costs and consequences of every action and exchange.
Air-drying laundry on a clothesline saves nearly 50 cents a load.
Add two weeks between those monthly haircuts and save at least $60 a year.
Buy heating oil in midsummer and save another $50 or more.
