Have you watched salmon leaping and jumping seemingly impossible hurtles to return to the place of their birth? Many times I've watched the ritual with wonder.

While we think of this migration as having gone on "forever" from sea to river to stream. It seems it is a relatively recent phenomenon.

Salmon have permeated First Nations mythology and have been prized as an important food source for thousands of years.

Researchers from Northwestern University and the University of Haifa say they have shown that areas of the brain associated with language work harder in girls than in boys during language tasks, and that boys and girls rely on different parts of the brain when performing these tasks.

Researchers have long believed that girls have superior language abilities to boys but no one has clearly provided a biological basis that may account for their differences.

“Our findings – which suggest that language processing is more sensory in boys and more abstract in girls -- could have major implications for teaching children and even provide support for advocates of single sex classrooms,” said Douglas D. Burman, research associate in Northwestern’s Roxelyn and Richard Pepper Department of Communication Sciences and Disorders.

The discovery of three-billion-year-old zircon microcrystals in northern Ontario by an international research team is providing a new record of the processes that form continents and their natural resources, including gold and diamonds.

From Gods To Avicenna

Originating as divine and supernatural, Greek medicine changed and moved toward analysis and logical thinking during the period 800 B.C. to 460 C.E.

Thales (636-546 B.C.), philosopher and scientist, undertakes examination about the laws of nature and physics. He supposed that water (moisture) was the first element from which the world was formed.

Empedocles (Agrigento c.495- c.435 B.C.) philosopher and physician, who lived in Sicily, wrote “On Nature” and “On Purification“. Its system was based on the interaction of the four elements (fire, air, earth and water), called by him “rhizomata” (roots) under the influence of love and hate (attraction and repulsion). He studied circulation of the blood and atmospheric pressure, foreshadowed view of evolution. He was the founder of Italian medicine.
