Long Before The Inca Colonized Peru, Natives Had A Thriving Trade Network
A new DNA analysis reveals that long before the Incan Empire took over Peru, animals were being transported across the Andes, a trek that also involved rainforests, highlands and deserts.
The analysis was of parrot feathers discovered at Pachacamac, Peru, a religious hub that is far outside the birds’ native rainforest range. The burial feather assemblage included the Scarlet Macaw, Blue-and-yellow Macaw, Red-and-green Macaw and Mealy Amazon. DNA sequencing, isotope chemistry and computational landscape modeling says the western side of the Andes was just as inhospitable to these species one thousand years ago as it is today.

The Creepy Uncanny Valley Of Targeted Online Marketing
Personalized online ads must work for the same reason advertising must work; it wouldn't be a trillion-dollar industry if it didn't work. Even supplements and organic food are only $140 billion, and those are really popular things that don't work. Advertising is not popular at all but good luck succeeding without it.
Yet there are limits for what people accept without being uncomfortable. In robots and animation, that has long been termed the 'uncanny valley' - where something is not lifelike enough to look real but too lifelike to be acceptable. Some digital marketing has its own uncanny valley; where it becomes unsettling. Examples are people who say they mentioned something in the presence of their Amazon Echo and then ads on Facebook began to target them.

Teens Are Getting Much Less Sleep Than In The Past
A new paper says teens are not getting enough sleep and a lot of parents with teenage children may disagree. Others reflexively blame phones and tablets.
It isn't a new concern, though. Nor is technology new in getting blame. In 1905, The Lancet published a study saying that kids in British boarding schools were getting less sleep than was healthy, and the reason was the new popularity of affordable lighting. “Late to bed and early to rise is neither physiological nor wise,” the authors wrote.
By the 1950s, the concern was in culture again, this time due to radio and television keeping children up. In all instances, overstimulation, mental health, and poor academic achievement is invoked.
