For the first time, scientists have identified cells in mice that are capable of regenerating new hair follicles when transplanted into the skin. The finding is likely to spur research into new hair loss treatments for humans.
The mystery of migrating monarch butterflies has captured the attention. of people throughout the world. East of the continental divide in North. America, monarchs generally migrate to central Mexico from as far away as. Ontario, Canada. Monarchs west of the divide fly to the coast of California. to spend the winter.

The most famous of butterflies, the Monarch butterfly, may be in danger of becoming extinct due to a decrease in their population, according to new report in January 2014. The danger comes from the shrinking of the forest ground in Central Mexico, where these butterflies go to spend the winter.he butterfly is also used as the emblem of the North American Free Trade Agreement. As the winter grounds become smaller, the Monarch Butterfly could become rare and even extinct. Andy Davis, a member of the research team recommends that people place the milkweed plant around their homes for the butterfly.
