Koalas are marsupials, a mammal that carries its young in a pouch. They live in the Eucalyptus forests of Australia and they only eat the new leaves of a few different types of eucalypt trees. Koala's paws are hand-like, strong, and have very sharp claws to help them hold onto tree trunks and branches.
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
