Australia Got a Wave of Migration from India About 4,000 Years Ago(link)

It was thought the continent had been largely isolated after the first humans arrived about 40,000 years ago until the Europeans moved in in the 1800s.

But DNA from Aboriginal Australians revealed there had been some movement from India during this period.

river

In 2011, the Mississippi River reached record levels. Massive floodgates had to be opened to divert water away from Baton Rouge and New Orleans, where the river rose to within feet of the tops of flood protection levees. Just one year later, droughts in the Midwest have dropped the river to a dangerously low level, threatening both the feasibility of freight transport and, due to rising salinity levels, the viability of New Orleans’s water supply. For the residents of Baton Rouge and New Orleans, however, the record flood of 2011 and low water of 2012 were barely perceptible events. After all, each city is largely divorced from the river, separated by the levee wall. The river has been engineered out of the daily lives of the people that live along it. Even more imperceptible is the massive environmental damage to the surrounding region that has resulted from human modifications to…

Advertizing is more sophisticated now. It is all about planting an idea in the mind of the customers. It is about Inception.

From Bunny advertizing Lijjat Papad to SRK promoting Fair and Handsome as a ‘Mardoon wali Cream’ to ”The roads are full of Idiots’ advert of CEAT tyres, there is a whole lot of sensible and utterly garish adverts to choose from. But does the customer choose wisely or are we just swooned away by big names? Is the advertizing industry considerate while playing with our sensibilities or do they sometimes thrive on our insecurities to make profits?

Here is my guest post on the topic on Akanksha’s blog.

Extraterrestrial lakes

At present the surface of the planet Mars is too cold and has too little atmospheric pressure to permit the pooling of liquid water on the surface. Geologic evidence appears to confirm, however, that ancient lakes once formed on the surface. It is also possible that volcanic activity on Mars will occasionally melt subsurface ice, creating large lakes. Under current conditions this water would quickly freeze and sublimate unless insulated in some manner, such as by a coating of volcanic ash.

Only one world other than Earth is known to harbor lakes, Saturn’s largest moon, Titan. Photographs and spectroscopic analysis by the Cassini–Huygens spacecraft show liquid ethane on the surface, which is thought to be mixed with liquid methane.

Jupiter’s small moon Io is volcanically active due to tidal stresses, and as a result sulfur deposits have accumulated on the surface. Some photographs taken during the Galileo mission appear to show lakes of liquid sulfur on the surface.There are dark basaltic plains on the Moon, similar to lunar maria but smaller, that are called lacus (singular lacus, Latin for “lake”) because they were thought by early astronomers to be lakes of water.
