Cooking ... the brain


"Brains demand exceptional amounts of energy," says Ed Yong at Discover Magazine — energy that raw food simply can't provide. That's where cooking comes in.
Writes Yong:
Our ancestors overcame this constraint when they learned how to cook. Cooked food offers more calories than raw food, and is easier to chew and digest. These early chefs could gain more energy from the same amount of eating time. That, in turn, fueled more neurons and larger brains.

Julius Caesar and the Parthian Wars

The previous post was on a book (in italian). In the fiction,  a time-traveler comes back from future in the Rome of 44 BCE, to save Julus Caesar's life. The book is entitled "The Parthian War".

Had Caesar ever been involved in Parthian Wars? Here from Wiki

"In 53 BC, Crassus led an invasion of Mesopotamia, with catastrophic results; at the Battle of Carrhae, the worst Roman defeat since the Battle of Cannae, Crassus and his son, Publius, were defeated and killed by a Parthian army under General Surena. The bulk of his force killed or captured; of 42,000 men, about half died, a quarter made it back to Syria, and the remainder became prisoners of war.[7] The following year, the Parthians launched raids into Syria, and in 51 BC mounted a major invasion led by the crown prince Pacorus and the general Osaces, but their army was caught in an ambush near Antigonea by the Romans under Cassius and Osaces was killed.[8]
During Caesar's civil war the Parthians made no move, but maintained relations with Pompey. After his defeat and death, a force under Pacorus came to the aid of the Pompeian general Caecilius Bassus, who was besieged at Apamea Valley by the Caesarian forces. With the civil war over, Julius Caesar elaborated plans for a campaign against Parthia, but his assassination averted the war. During the ensuing Liberators' civil war, the Parthians actively supported Brutus and Cassius, sending a contingent which fought with them at the Battle of Philippi in 42 BC.[9]

Cupriavidus metallidurans

"The ability to create gold from base materials has eluded alchemists since the Middle Ages, but two U.S. university professors have found a way to produce small amounts of gold using metal-loving bacteria to make the magic. ... the two professors at Michigan State University found that a certain type of metal-loving bacteria can transform high amounts of the toxic chemical compound gold chloride from a liquid into solid 24-karat gold. " Kazem Kashefi, assistant professor of microbiology and molecular genetics at Michigan State University and Adam Brown, associate professor of electronic art and intermedia at Michigan State, found that the bacteria, Cupriavidus metallidurans, can withstand concentrations of gold chloride 25 times higher than previously reported by scientists.
