TEXTO PARA A QUESTÃO
A study carried out by Lauren Sherman of the University of California and her colleagues investigated how use of the “like” button in social media affects the brains of teenagers lying in body scanners.
Thirty-two teens who had Instagram accounts were asked to lie down in a functional magnetic resonance imaging (fMRI) scanner. This let Dr. Sherman monitor their brain activity while they were perusing both their own Instagram photos and photos that they were told had been added by other teenagers in the experiment. In reality, Dr. Sherman had collected all the other photos, which included neutral images of food and friends as well as many depicting risky behaviours like drinking, smoking and drug use, from other peoples’ Instagram accounts. The researchers told participants they were viewing photographs that 50 other teenagers had already seen and endorsed with a “like” in the laboratory.
The participants were more likely themselves to “like” photos already depicted as having been “liked” a lot than they were photos depicted with fewer previous “likes”. When she looked at the fMRI results, Dr. Sherman found that activity in the nucleus accumbens, a hub of reward circuitry in the brain, increased with the number of “likes” that a photo had.

TEXTO PARA A QUESTÃO
Plants not only remember when you touch them, but they can also make risky decisions that are as sophisticated as those made by humans, all without brains or complex nervous systems.
Researchers showed that when faced with the choice between a pot containing constant levels of nutrients or one with unpredictable levels, a plant will pick the mystery pot when conditions are sufficiently poor.
In a set of experiments, Dr. Shemesh, from Tel✄Hai College in Israel, and Alex Kacelnik, from Oxford University, grew pea plants and split their roots between two pots. Both pots had the same amount of nutrients on average, but in one, the levels were constant; in the other, they varied over time. Then the researchers switched the conditions so that the average nutrients in both pots would be equally high or low, and asked: Which pot would a plant prefer?
When nutrient levels were low, the plants laid more roots in the unpredictable pot. But when nutrients were abundant, they chose the one that always had the same amount.

A new planet in our neighborhood - how likely is life there?
By Don Lincoln, August 24, 2016
Scientists working at the European Southern Observatory (ESO), using the La Silla telescope, claim to have discovered the closest exoplanet to Earth. Exoplanet means planets orbiting stars other than the Sun. Most of them are huge planets orbiting very near their star. The newly discovered planet, which orbits Proxima Centauri, a star within the so-called “habitable zone”, has been named Proxima b.
Proxima Centauri is a red dwarf, which is the most common type of star in the galaxy. Red dwarfs are much smaller than our Sun, and are very dim. For instance, in the visible spectrum that we use to see, Proxima Centauri gives off 0.0056% as much light as the Sun.
So what about life? Are there any chances that an alien lizard might bask in Proxima Centauri’s light or try to find shade under an alien tree? Dr. Guillem Anglada-Escudé, co-author of the research from London University, believes that “there is a reasonable expectation that this planet might be able to host life”
But this belief is not consensual as other scientists think the prospect of life is improbable. Although the temperature of the planet is thought to be such that liquid water could exist, it is unlikely that Proxima b is habitable, as the planet is subject to stellar wind pressures of more than 2000 times those experienced by Earth from the solar wind. These winds would likely blow any atmosphere away, leaving the undersurface as the only vaguely habitable location on that planet. You shouldn’t imagine, thus, a lush and verdant world, with lovely blue waters, sandy beaches and green plants.
So, what’s the bottom line? First, the discovery is extremely exciting. The existence of a nearby planet in the habitable zone will perhaps increase the interest in efforts like Project Starshot, which aims to send microprobes (instruments that apply a stable and wellfocused beam of charged particles -electrons or ions- to a sample) to Proxima Centauri. On the other hand, Proxima b is unlikely to be a haven for people trying to escape the ecological issues of Earth, so we should not view this discovery as a way to ignore our own ecosystem.

The Future of Jobs
http://www3.weforum.org/docs/WEF_Future_of_Jobs.pdf Acessado em 19/09/2016
Today, we are at the beginning of a Fourth Industrial
Revolution. Developments in genetics, artificial intelligence,
robotics, nanotechnology, 3D printing and biotechnology, to
name just a few, are all building on and amplifying one
another. This will lay the foundation for a revolution more
comprehensive and all-encompassing than anything we have
ever seen. Smart systems — homes, factories, farms, grids or
cities — will help tackle problems ranging from supply chain
management to climate change. The rise of the sharing
economy will allow people to monetize everything from their
empty house to their car.

People Bought Thousands of Hammocks and Crockpots on Amazon Prime Day

By Brad Tuttle July 13, 2016
Maybe Amazon heard all of the complaints about Prime Day from last year and really took them to heart. Some combination of more competitive pricing, a better selection of deals, more awareness among shoppers, and the fact that there are simply way more Amazon Prime members compared with a year ago appears to have made the second edition of Prime Day, held on July 12, a huge success in terms of generating sales.

Why Finnish babies sleep in cardboard boxes
By Helena Lee, BBC News 4 June 2013 http://www.bbc.com/news/magazine-22751415
For 75 years, Finland's expectant mothers have been given a box by the state. It's like a starter kit of clothes, sheets and toys that can even be used as a bed. And some say it helped Finland achieve one of the world's lowest infant mortality rates.
