Not far from the tree
By Mariana de Viveiros
They say the apple doesn’t fall far from the tree. So, the son of a circus performer is likely to be also an artist himself. 12-year-old Matheus Felipe Jesus Silva was born in the circus. That is, ever since he was a baby, he’s lived in a trailer (a mobile home pulled by a car or a truck). His mother is a ballet dancer at CircoSpacial, where Matheus himself is also a performer since the age of 3. He started doing presentations with clowns and nowadays he is a trapeze artist (just like his dad, who works in Europe), equilibrist and acrobat.
As the circus travels all over Brazil, Matheus changes schools very often. He studies in the morning, has rehearsals in the afternoon and, at weekends, he performs in the circus ring. He says that this routine doesn’t disturb his studies and he wants to graduate in Physical Education. “But I want to work in the circus forever.” On account of the mobility of his life and his outgoing nature, Matheus makes new friends wherever he goes and keeps in touch with them through the internet. “Kids think that I have a peculiar way of life and come to the circus to watch my show,” he adds. On his days off, he likes to go to the movies, to the mall and to shows. Read on to see his favorite film, book, CD and website.

Which means of communication does Matheus usually use to get in touch with his pals?
Every day, fake pictures are getting more realistic. Today, anyone can access a web-based program like Midjourney or Dall-e and create artificial or manipulated images without much effort. The good news is that humans have a natural instinct for sniffing them out, according to Siwei Lyu, professor of computer science and engineering at the University at Buffalo. Lyu belongs to a group of researchers battling AI with AI—they’ve found the best way to teach an AI to find synthetic images is to show them how humans do it. We’ve been dealing with falsified images for a very long time. Image manipulation has been around just about as long as photography itself. What’s changed is how easy it is for someone without expertise to create something that appears genuine—resulting in an intimidating volume of synthetic images. But Lyu urges us not to panic. Here’s how to use our natural instincts to find things that aren’t quite right—and how to keep up with the lightning speed of AI advancement.
If there is a person in an image, look at their hands and eyes. Current AI programs aren’t good at producing lifelike hands—they may have six fingers, or fingers that are all the same length or in a strange pose. In March, an AI-generated image of Pope Francis wearing a Balenciaga puffer coat went viral. If you look closely at his hand, he’s holding his coffee by the lid’s tab—a strange way to hold it, even if the cup was empty. And why the eyes? Humans are really sensitive to minute characteristics of the face. Humans almost always have circular pupils, but AI often produces strangely shaped shadows in the center of the eye. Light reflecting off the eyes should also be in the same place on each eye, something that current AI struggles with.

The end of life on Earth?
It weighted about 10,000 tons, entered the
atmosphere at a speed of 64,000 km/h and exploded
over a city with a blast of 500 kilotons. But on 15
February 2013, we were lucky. The metereorite that
[05] showered pieces of rock over Chelyabinsk, Russia, was
relatively small, at only about 17 metres wide. Although
many people were injured by falling glass, the damage
was nothing compared to what had happened in Siberia
nearly one hundred years ago, when a relatively small
[10] object (approximately 50 metres in diameter) exploded in
mid-air over a forest region, flattening about 80 million
trees. If it had exploded over a city such as Moscow or
London, millions of people would have been killed.
By a strange coincidence, the same day that the
[15] meteorite terrified the people of Chelyabinsk, another
50m-wide asteroid passed relatively close to Earth.
Scientists were expecting that visit and know that the
asteroid will return to fly close by us in 2046, but the
Russian meteorite earlier in the day had been too small
[20] for anyone to spot.
Most scientists agree that comets and asteroids
pose the biggest natural threat to human existence. It
was probably a large asteroid or comet colliding with
Earth which wiped out the dinosaurs about 65 million
[25] years ago. An enormous object, 10 to 16 km in diameter,
struck the Yucatan region in Mexico with the force of 100
megatons. That is the equivalent of one Hiroshima bomb
for every person alive on Earth today.
Many scientists, including the late Stephen
[30] Hawking, say that any comet or asteroid greater than
20km in diameter that hits Earth will result in the
complete destruction of complex life, including all
animals and most plants. As we have seen even a much
smaller asteroid can cause great damage.
[35] The Earth has been kept fairly safe for the last 65
million years by good fortune and the massive
gravitational field of the planet Jupiter. Our cosmic
guardian, with its stable circular orbit far from the sun,
sweeps up and scatters away most of the dangerous
[40] comets and asteroids which might cross Earth’s orbit.
After the Chelyabinsk meteorite, scientists are now
monitoring potential hazards even more carefully but, as
far as they know, there is no danger in the foreseeable
future.
[45] Types of space rocks
• Comet – a ball of rock and ice that sends out a
tail of gas and dust behind it. Bright comets only appear
in our visible night sky about once every ten years.
• Asteroid – a rock a few feet to several kms in
[50] diameter. Unlike comets, asteroids have no tail. Most
are to small to cause any damage and burn up in the
atmosphere.
• Meteoroid – part of an asteroid or comet.
• Meteorite – what a meteoroid is called when it
[55] hits Earth.

Introduction to Human Evolution
Human evolution
Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years.
One of the earliest defining human traits, bipedalism -- the ability to walk on two legs -- evolved over 4 million years ago. Other important human characteristics -- such as a large and complex brain, the ability to make and use tools, and the capacity for language -- developed more recently. Many advanced traits -- including complex symbolic expression, art, and elaborate cultural diversity -- emerged mainly during the past 100,000 years.
Humans are primates. Physical and genetic similarities show that the modern human species, Homo sapiens, has a very close relationship to another group of primate species, the apes. Humans and the great apes (large apes) of Africa - - chimpanzees (including bonobos, or so-called “pygmy chimpanzees”) and gorillas -- share a common ancestor that lived between 8 and 6 million years ago. Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa.
Most scientists currently recognize some 15 to 20 different species of early humans. Scientists do not all agree, however, about how these species are related or which ones simply died out. Many early human species -- certainly the majority of them – left no living descendants. Scientists also debate over how to identify and classify particular species of early humans, and about what factors influenced the evolution and extinction of each species.
Early humans first migrated out of Africa into Asia probably between 2 million and 1.8 million years ago. They entered Europe somewhat later, between 1.5 million and 1 million years. Species of modern humans populated many parts of the world much later. For instance, people first came to Australia probably within the past 60,000 years and to the Americas within the past 30,000 years or so. The beginnings of agriculture and the rise of the first civilizations occurred within the past 12,000 years.

TEXTO:
New photos of a huge crater on Mars suggest water
may lurk in crevices under the planet’s surface, hinting
that life might have once lived there, and raising the
possibility that it may live there still, researchers say.
[5] Future research looking into the chances of life on Mars
could shed light on the origins of life on Earth, scientists
added. […]
Space agencies have deployed many missions to
Mars over the decades to explore how habitable its
[10] surface may have been or is today. However, the Martian
surface has been extremely cold, arid and chemically
hostile to life as we know it for most of the history of
Mars. Instead of scanning the surface of Mars for life,
scientists have suggested the most viable habitat for
[15] ancient simple life may have been in Martian water hidden
underground.
On Earth, microbes up to 3 miles or more
underground make up perhaps half of all of the planet’s
living matter. Most of these organisms represent some
[20] of the most primitive kinds of microbes known, hinting
that life may actually have started underground, or at
least survived there during a series of devastating cosmic
impacts known as the Late Heavy Bombardment that
Earth and the rest of the inner solar system endured
[25] about 4.1 billion to 3.8 billion years ago.
Since Mars has less gravity — a surface gravity of
a little more than one-third Earth’s — its crust is less
dense and more porous than that of our planet,
which means that more water can leak underground,
[30] researchers said. Wherever there is liquid water on Earth,
there is virtually always life, and microbes underground
on Mars could be sustained by energy sources
and chemical reactions similar to those that support
deep-dwelling organisms on Earth.
[35] “The deep crust has always been the most habitable
place on Mars, and would be a wise place to search for
evidence for organic processes in the future,” Michalski
[of the Planetary Science Institute in Tucson, Ariz.] told
SPACE.com.
