Não desejei a morte de minha filha. Ou desejei? Aí é que reside a dúvida, é onde habita o nó que nada nem ninguém no mundo tem o poder de desatar. O inconsciente, desculpe-me a vulgaridade do termo, minha filha, é uma merda. Sendo autônomo, o inconsciente age por si, sem pedir licença nem se revelar. Desejei ou não a morte de minha filha, hein? Você pode responder a essa pergunta? Alguém pode? Eu não posso. Busquei na fonte a resposta e ela não veio. Como minha filha havia feito, busquei nas águas do Cristal a cura imediata para uma dor que parecia infinda. A ferida tinha sido cavada pelas águas, então elas que tratassem de cicatrizá-la. O rio recusou meu corpo, mas não a dor. Nem o aconselhamento. Pediu tempo, apenas. Permaneci plantada no barranco, juntando ao seu caudal minhas lágrimas secas. Disseram que eu tinha enlouquecido, talvez tivesse mesmo. Em diálogo profundo, as águas me fizeram compreender verdades para as quais eu nunca havia me atinado. Todo rio tem seu leito, suas margens, seu limite, toda vez que ele avança além de seu leito original provoca estragos, descalabros. O rio de nossa vida não é diferente. Ele também está sujeito a limitações intransponíveis. Existe você e você; seu campo de visão, a capacidade de administrar o próprio caudal. Tem a hora de abrir e a hora de fechar as comportas. Felicidade ou dor, a escolha é sua, depende do grau de intensidade que você der a cada coisa. Hoje posso dizer que me conheço um pouquinho, mesmo assim, perguntas continuam sem resposta.

TEXTO 3
Escalada para o inferno
Iniciava-se ali, meu estágio no inferno. A ardida solidão corroía cada passo que eu dava. Via crucis vivida aos seis anos de idade, ao sol das duas horas. Vermelhidão por todos os lados daquela rua íngreme e poeirenta. Meus olhos pediam socorro mas só encontravam uma infinitude de terra e desolação. Tentava acompanhar os passos de meu pai. E eles eram enormes. Não só os passos mas as pernas. Meus olhos olhavam duplamente: para os passos e para as pernas e não alcançavam nem um nem outro. Apenas se defrontavam com um vazio empoeirado que entrava no meu ser inteiro. Eu queria chorar mas tinha medo. Tropeçava a cada tentativa de correr para alcançar meu pai. E eu tinha medo de ter medo. E eu tinha medo de chorar. E era um sofrimento com todos os vórtices de agonia. À minha frente, até onde meus olhos conseguiram enxergar, estavam os pés e as pernas de meu pai que iam firmes subindo subindo subindo sem cessar. À minha volta eu podia ver e sentir a terra vermelha e minha vida envolta num turbilhão de desespero. Na verdade eu não sabia muito bem para onde estava indo. Eu era bestializado nos meus próprios passos. Nas minhas próprias pernas. Tinha a impressão que o ponto de chegada era aquele redemoinho em que me encontrava e que dele nunca mais sairia. Na ânsia de ir sem querer ir eu gaguejava no caminhar. E olhava com sofreguidão para os meus pés e via ainda com mais aflição que os bicos de meus sapatos novos estavam sujos daquela poeira impregnante, vasculhante, suja. Eu sempre gostei de sapatos. Eu sempre gostei de sapatos novos. Novos e luzidios. E eles estavam sujos. Cobertos de poeira. E a subida prosseguia inalterada. Tentava olhar para o alto e só conseguia ver os enormes joelhos de meu pai que dobravam num ritmo compassado. Via suas pernas e seus pés. E só. Sentia, lá no fundo, um desejo calado de dizer alguma coisa. De dizer-lhe que parasse. Que fosse mais devagar. Que me amparasse. Mas esse desejo era um calo na minha pequenina garganta que jamais seria curado. E eu prossegui ao extremo de meus limites. Tinha de acontecer: desamarrou o cadarço de meu sapato. A loucura do sol das duas horas parece ter se engraçado pelo meu desatino. Tudo ficou muito mais quente. Tudo ficou mais empoeirado e muito mais vermelho. O desatino me levou ao choro. Não sei se chorei ou se choraminguei. Só sei que dei índices de que eu precisava de meu pai. E ele atendeu. Voltou-se para mim e viu que estava pisando no cadarço. Que estava prestes a cair. Então me socorreu. Olhou-me nos olhos com a expressão casmurra. Levou suas enormes mãos aos meus pés e amarrou o cadarço firmemente com um intrincado nó. A cena me levou a um estado de cegueira anestésica tão intensa que sofri uma espécie de amnésia passageira. Estado de torpor. Quando dei por mim, já tinha chegado ao meu destino: cadeira do barbeiro. Alta, prepotente e giratória. Ele, o barbeiro, cabeça enorme, mãos enormes, enormes unhas, sorriso nos lábios dos quais surgiam grandes caninos. Ele portava enorme máquina que apontava em minha direção. E ouvi a voz do pai: pode tirar quase tudo! deixa só um pouco em cima! Ali, finalmente, para lembrar Rimbaud, ia se encerrar meu estágio no inferno.

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.

According to the text, it is CORRECT to state that
Improving with age? How city design is adapting to older populations
There is no denying it: like it or not we are all getting older. According to the UN World Population Prospects
report, the global population of older people is growing at an unprecedented rate. By 2050, for the
first time in human history, there will be more over-65s than children under 15. The number of people over
100 will increase by 1,000%. And as by then 70% of the world’s population will likely live in cites, this will
present huge challenges, and cities will need to adapt. “Small innovations can make a difference,” Recalcati
adds. “Older people are less likely to drive, favouring public transport and walking. The average person
over 65 manages a walking speed of 3km/hour. At 80 that goes down to 2km/hour, compared with the
average for a working age person of 4.8km/hour. Reducing the distance between transport stops, shops,
benches, trees for shade, public toilets and improving pavements and allowing more time to cross the
road all encourage older people to go out.” In the UK, the government has just announced the building
of 10 new towns designed to address ageing and health issues such as obesity. As well as encouraging
more active lifestyles, the designs could include wider pavements, few trip hazards and moving LCD
signs, making the streets easier to navigate for people with dementia and other age-related conditions.
London-based charity Living Streets has also been working alongside communities carrying out street
audits with older residents to see what improvements could be made, as well as campaigning at a strategic
level to influence positive legislative and infrastructure changes. Their project Time to Cross campaigned
to increase pedestrian crossing times which resulted in Transport for London (TfL) agreeing to a
review.

I. Old people walk slowly, so they prefer driving.
II. The adaptions mentioned refer not only to elderly but also to obese people.
III. Population is helping to make improvements.

Dreaming brain rhythms lock in memories
It is the clearest evidence to date that REM sleep is critical for memory. By switching off certain brain cells, the researchers silenced a particular, rhythmic type of brain function - without waking the mice. If they did this during REM sleep, the mice failed subsequent memory tests. The research is reported in the journal Science.
REM sleep is the phase during which, at least in humans, dreams take place - but the question of whether it is important for settling new memories has been difficult to answer. Recent studies have tended to focus on deep, non-REM sleep instead, during which brain cells fire in various patterns that reflect memory consolidation and "re-play" of the day's experiences. During REM sleep, while our eyes flicker and our muscles relax, exactly what the brain is doing is something of a mystery. But it is a type of sleep seen across the animal kingdom, in mammals and birds and even lizards.Read the text.
Amazon keeps expanding its empire
Elizabeth Weise
Amazon has doubled the number of air freight cargo planes it is leasing, a further build out of its internal delivery system.
Atlas Air Worldwide on Thursday said it had signed an agreement with the Seattle internet retailer to operate 20 Boeing 767 for the company for ten years.
Operations under the agreements are expected to begin in the second half of 2016 and ramp up to full service through 2018, Atlas said.
In addition, Amazon will acquire as much as 20% of Atlas.
The planes will be used to move packages between Amazon’s fulfillment centers, which package goods, to its sortation centers, which sort them into local delivery pallets that can be taken to the Post Office for bulk delivery, the company said.
The planes will also be used by Amazon to move goods between its fulfillment centers across the country to other centers where they are needed for one- and two-day delivery, as no one Amazon center can stock the 20 million items Amazon typically has available for two-day delivery.
The deal isn't surprising, said John Haber, CEO of Spend Management Experts, a supply chain management consulting firm.
“This is just the most recent step in Amazon building out a massive logistics network designed to move more of their transportation and distribution under their direct control," he said.
