Coralline algae in the Mediterranean lost their tropical element between 5 and 7 million years ago
An international team of researchers has studied the coralline algae fossils that lived on the last coral reefs of the Mediterranean Sea between 7.24 and 5.3 million years ago. Mediterranean algae and coral reefs began to resemble present day reefs following the isolation of the Mediterranean from...

For some who have lost their sense of smell, a once popular asthma drug could help
SAN DIEGO, CA -- Despite the fact that millions of Americans are believed to have lost
