…not fish! – The kinds of fish available for your dinner table will change radically in the near future, thanks to global warming. When you next go to the store to buy fish, you may be in for some surprises?your favorite kinds may simply not be available any more. Or there may be nothing there at all, since the recent massive flooding of cities and farms in the Mississippi River basin has washed nitrogen fertilizer into commercial fishing areas of the ocean, causing “dead zones” where no fish can live.

Why did prehistoric cave artists pick certain walls?and not others?on which you paint their beautiful images? Their choices may have to do with acoustics.

Prehistoric artists may have painted the areas in their caves where singing, humming and music sounded best. Scientists have found that humming into some bends in a decorated cave wall produced sounds like those made by the animals painted on it.

In LiveScience.com, Heather Whipps quotes researcher Iegor Reznikoff as saying, “Why would the Paleolithic tribes choose preferably resonant locations for painting, if it were not for making sounds and singing in some kind of ritual celebrations related with the pictures?”

Want to slow the signs of aging and live longer? Yes, there is a “fountain of youth,” but you’re not going to like it?it can be summed up in two words: eat less.

Calorie restriction has long been shown to slow the aging process in rats and mice. While scientists do not know how calorie restriction affects the aging process in rodents, one popular hypothesis is that it slows aging by decreasing a thyroid hormone called T3, which then slows metabolism and tissue aging. A new study shows that cutting approximately 300 to 500 calories per day from your diet has a similar biological effect in humans and, therefore, may slow the aging process.

It sure would be a relief for folks in California if they could predict the big one some OTHER way than looking for swarms of frogs. Soon they may be able to.

Researchers have found that stress-induced changes occurred in rocks a few hours before two small quakes in the San Andreas Fault area.

BBC News quotes researcher Paul Silver as saying, “If you had 10 hours’ warning, from a practical point of view, you could evacuate populations, you could certainly get people out of buildings, you could get the fire department ready. Hurricane [warnings] give you an idea of what could be done.”
