How ghost cities in the Amazon
are rewriting the story of civilisation
Try to imagine an environment largely untouched by humans
and the Amazon rainforest might spring to mind. After all, large
swathes of this South American landscape are blanketed in thick
vegetation, suggesting it is one corner of the world that humans
never managed to tame. Here, there must have been no
deforestation, no agricultural revolution and no cities. It seems
like a pristine environment.
Or so we thought. But a very different picture is emerging.
Archaeologists working with Indigenous communities have been
shown crumbling urban remains and remote sensing technologies
such as LiDAR (Light Detection and Ranging) are revealing the
footprints of vast ghost cities. With so much evidence of ancient
human activity, it is now thought the pre-Columbian Amazon was
inhabited by millions of people – some living in large built-up
areas complete with road networks, temples and pyramids.
But that’s not all this research reveals. Paradoxically, it also
provides evidence that the traditional view of the Amazon isn’t
completely wide of the mark. For instance, while the ancient
Amazonians managed their landscape intensively, they didn’t
deforest it. And although they developed complex societies, they
never went through a wholesale agricultural revolution. This
might suggest that the pre-Columbian Amazonians broke the
mould of human cultural development, which is traditionally seen
as a relentless march from hunting and gathering to farming to
urban complexity. The truth is more surprising. In fact, we are
now coming to understand that there was no such mould –
civilisation arose in myriad ways. What looks like an anomaly in
the Amazon is actually a shining example of a process that was as
vibrant and diverse as the rainforest itself.

Nothing Gold Can Stay
Nature’s first green is gold,

Her early leaf’s a flower;

What’s good about personalized medicine
For a long time, the practice of medicine has largely been
reactive, waiting for the onset of disease before treating or curing
it. But we’re all unique in terms of genetic makeup, environment,
and lifestyle factors. Our growing understanding of genetics and
genomics – the study of all of a person’s genes – and how they
drive health, disease and treatment in individual people offers an
opportunity to step away from a ‘one size fits all’ approach based
on broad population averages and adopt an individualized
approach.
In addition to advances in the field of genomics,
developments in the fields of science and technology play a
crucial role in personalized medicine (for example, the
development of high-resolution analytics, biotech research and
chemistry, and the ability to decipher molecular structures,
signaling pathways, and protein interactions that underpin the
mechanisms of gene expression).
Personalized medicine is about more than prescribing the
best drugs, although that’s a large part of it. Proponents say it
would shift medicine’s emphasis from reaction to prevention,
better predict disease susceptibility and improve diagnosis,
produce more effective drugs and reduce adverse side effects,
and eliminate the inefficiency and cost of adopting a trial-anderror approach to healthcare. […]
Despite its numerous benefits, the adoption of a personalized
medicine approach raises several issues. For it to reach peak
efficiency, a lot of genomic data must be collected from a large
and diverse section of the population, and it’s critical that
participants’ privacy and confidentiality are protected.

Biologia
O dogma central da biologia molecular assim descreve o fluxo da informação genética: do DNA (via
transcrição) para o RNA e, subsequentemente, para as proteínas (via tradução). Nesse mesmo dogma,
podem-se incluir a duplicação do DNA e a transcrição reversa, do RNA para o DNA.
Considere as afirmações abaixo, quanto à tradução de proteínas em eucariotos.
I - O ribossomo é uma proteína globular, responsável pelo pareamento entre as moléculas de tRNAs, que transportam os aminoácidos, e a molécula de mRNA, que codifica a estrutura da proteína a ser sintetizada.
II - Os tRNAs são moléculas que possuem dois sítios de ligação, um capaz de ligar-se especificamente a um aminoácido e outro denominado anticódon, capaz de reconhecer uma sequência de três nucleotídeos presente em um mRNA.
III- Os códons presentes no mRNA são reconhecidos pela subunidade pequena do ribossomo e são transformados quimicamente nos aminoácidos correspondentes, para gerar uma proteína.
Quais estão corretas?

A famosa frase de Carl Sagan, "O cosmos está dentro de nós. Somos feitos de poeira estrelar", resume
um conceito fundamental da astrofísica. Quatro décadas mais tarde, a astrofísica Suzanna Randall
(Observatório Europeu do Sul) explicou melhor esse conceito: em estrelas supermassivas, a fusão
nuclear continua mesmo após o esgotamento do hidrogênio, utilizando hélio para gerar elementos
mais pesados essenciais à vida, como carbono, nitrogênio e oxigênio.

Biologia
Analogia e homologia são conceitos fundamentais na biologia evolutiva e comparada, pois descrevem
relações de semelhança entre estruturas e órgãos de diferentes organismos. Estruturas análogas são
aquelas que apresentam a mesma função, mas possuem origem embrionária distinta (exemplo: asas
de abelhas e de aves). Estruturas homólogas, por sua vez, compartilham a mesma origem embrionária,
podendo ter funções diferentes ou iguais (exemplo: nadadeiras peitorais de uma baleia e membros
superiores em humanos).
Com base no texto acima, assinale com V (verdadeiro) ou F (falso) as afirmações abaixo.
( ) Os túbulos de Malphigi, em insetos, são análogos aos rins em mamíferos.
( ) Os ossos do ouvido médio, em primatas, têm origem embrionária nas cartilagens dos arcos branquiais.
( ) As brânquias, em peixes, são estruturas homólogas aos pulmões em répteis.
