Ghost In Your Genes geocities.com/ariainvictus

http://www.geocities.com/ariainvictus/ Biology stands on the brink of a shift in the understanding of inheritance. The discovery of epigenetics � hidden influences upon the genes could affect every aspect of our lives. At the heart of this new field is a simple but contentious idea that genes have a ‘memory’. That the lives of your grandparents the air they breathed, the food they ate, even the things they saw can directly affect you, decades later, despite your never experiencing these things yourself. And that what you do in your lifetime could in turn affect your grandchildren. The conventional view is that DNA carries all our heritable information and that nothing an individual does in their lifetime will be biologically passed to their children. To many scientists, epigenetics amounts to a heresy, calling into question the accepted view of the DNA sequence a cornerstone on which modern biology sits. Epigenetics adds a whole new layer to genes beyond the DNA. It proposes a control system of ’switches’ that turn genes on or off � and suggests that things people experience, like nutrition and stress, can control these switches and cause heritable effects in humans.

Battleship Blücher sinks in WW1

On 24 January 1915, Blücher was part of the German squadron commanded by Vice Admiral Franz Hipper that was surprised by a superior British force of five battlecruisers, under Vice Admiral David Beatty on HMS Lion, at the Battle of Dogger Bank. Due to a misunderstanding of Beatty's orders, the British ships concentrated their fire on Blücher, the slowest and rearmost ship of the retreating German line of battle. She was bombarded by heavy fire from four of the five battlecruisers and finally sunk by torpedoes. 792 of her crew went down with her. 260 were rescued by Beatty's ships.
