obvious cause of death. Marine biologists have been unable to find the cause of
these deaths. They suspect that the Red Tide off of the coast of southwest
Florida has some connection with these mysterious deaths. A red tide is a
bloom of flagellates which are deadly to marine life, but cause no harm to the
human population. Another possible cause is a virus that is unknown to
scientists. Many people believe that this ...

In addition, unique patterns are also formed by the surface on which the tool is used. Wood, meat, hide, and bone all leave dissimilar scars on a lithic device. Modern archaeologists have devised a method, called use-wear analysis...
A star is a large ball of hot gas, thousands to millions of kilometers in diameter, emitting large amounts of radiant energy from nuclear reactions in its interior. differ fundamentally from planets in that they are self-luminous, whereas planets shine by reflected sunlight. Except for the SUN, which is the nearest star, stars appear only as point...
have been a mistery for scientists from the day they where discovered. act like viruses but they are not. Their structure and chemistry are unknown. They are believed to be proteins but that is yet to be completely proved. Prion stands for 'proteinaceous infectious particles'. are known to cause many diseases involved with nervous systems like...
