What is the universe made of? What is the biological basis of consciousness? How long can the human life span be extended?
In recent decades, scientists have discovered that the ordinary matter that makes up stars, planets, even human beings, accounts for only 5 percent of everything in the universe. The rest belongs to dark matter and dark energy, phenomena that scientists are just now learning about
What Is the Biological Basis of Consciousness?
In the 17th century, French philosopher and mathematician Ren Descartes declared that mind and body are entirely separate, leaving the debate over the nature of consciousness to other philosophers.
Today scientists are challenging that notion with a view that consciousness arises from the properties and the organization of neurons in the brain. Experimental work to unravel those properties and processes has only just begun
HOW LONG CAN HUMAN LIFE SPAN BE USED?
Life-span extension experiments in yeast, worms, and mice have convinced some scientists that humans may soon routinely coast beyond their hundredth birthdays. Other scientists say the human life span may be more limited.
