Baby giant water bugs, like true bugs, have piercing-sucking mouthparts. Water bugs catch small fish, stab them with their beak-like mouthparts and squirt special juices into the fish. These juices change the fish's insides into a soft goo - perfect for 'babies' to slurp up.
Could giving blood cut heart attack risk?
Could giving blood cut heart attack risk? New research shows that large blood loss (such as
donating blood) reduces stockpiled iron in our bodies. Large
amounts of stored iron were useful in premodern times, but now may
be doing us more harm than good. Excess iron may increase the risk
of heart attacks, liver cancer and even brain disorders. Losing
blood is the only way to reduce iron stores, so donating blood
regularly doesn't only benefit others, it may help you live
longer! DECEMBER 12, 2000
