Scientists Date Publication Of The Iliad

Scientists who decode the genetic history of humans by tracking how genes mutate have applied the same technique to one of the Western world’s most ancient and celebrated texts to uncover the date it was first written.

The text is Homer’s Iliad, and Homer – if there was such a person – probably wrote it in 762 B.C., give or take 50 years, the researchers found. The Iliad tells the story of the Trojan War – if there was such a war – with Greeks battling Trojans.

rhamphotheca: Electric Charge Keeps Bubbles Alive for Hours by Tracy Staedter Anyone who has ever made bubbles knows the joy of a big one and the instant disappointment when it pops. A bubble is made of fluid layered between two thin films of soap that eventually succumb to gravity. And it usually happens within seconds. But there’s a way to make bubbles last much longer, maybe even for hours. Researchers from the University of Lyon in France found that if they trapped a bubble between two platinum electrodes and delivered a charge, the soap flowed upward against gravity. The bubble’s walls became thicker and more stable and even changed colors. The research gives new insight into the strange world of fluid dynamics and could help improve experiments with lab-on-a-chip technologies… (read more: Discovery NEWS)
