1 . My name is Arianna Traviglia and I’m a senior cultural and heritage researcher at the Centre for Cultural Heritage Technology at the Italian Institute of Technology in Genoa, Italy.
As head of the team, I encourage the development of new technologies to maintain and protect important archaeological (考古学的) findings. Right now, I am working in the field of Pompeii, an ancient Roman city which was destroyed and buried under 13 to 20 feet of ash and small rocks during a volcanic eruption in 79 AD. With the help of a robot, I try to carefully reconstruct (重建) the city’s 2,000-year-old broken frescoes (壁画). The project is called RePAIR.
There are thousands of fresco pieces in Pompeii, and it was nearly impossible for a human to reconstruct all the irregular pieces into big, meaningful paintings in the past. Technology now allows us to do it-the robot we use is running by artificial intelligence (AI). As it examines a piece, it searches a database for a match, and then sends the data back to its hands to fit matching pieces together, saving a lot of hours. Its soft human-like arms and hands allow it to hold and examine the easily broken pieces without damaging them. The technology is likely to allow many museums around the world to reconstruct large-scale broken frescoes or similar objects in the future.
In RePAIR, I’m studying the hyperspectral (高光谱的) images of the fresco pieces in storage and comparing them with the paintings on the walls of the House of the Painters at Work, part of a building in Pompeii. By comparing the resemblances in the images, we will be able to work out whether the broken pieces were from the same wall.
I studied history and archaeology in college. Archaeology helps us understand where we come from, and technology enriches that exploration. I’m glad I’m a translator of the two worlds. My mind runs wild when I think about the exciting Roman life that we are still missing because Pompeii’s frescoes were damaged and haven’t been reconstructed.

3 . Frozen in time, a 125-million-year-old mammal attacking a dinosaur. A 39-million-year-old whale, the heaviest animal that ever lived. The oldest known jellyfish, from 505 million years ago. Paleontology (古生物学) produces newsworthy discoveries.
Fossils (化石), moreover, provide direct evidence for the long history of life, allowing paleontologists to test hypotheses (假设) about evolution with data only they provide. They allow investigation of present and past life on Earth. Flows of biological diversity, appearances of new life forms and the extinctions of long existing ones, would go undiscovered without these efforts. But the headlines over exciting new fossils greatly underestimate the true importance of paleontology. Its real significance lies in how such discoveries brighten the grand history of life on Earth. From its beginnings, more than three billion years ago, to the present day, fossils record how life adapted or disappeared in the face of major environmental challenges.
Paleontologists provide us with a unique vantage on modern climate change. They play an essential role in interpreting ancient environments, in reconstructing ancient oceans, continents and climates. Fossils provide key limitation on the climate models that are essential for predicting future climate change. And the fossil record gives important insights into how life will respond to predicted future climate conditions, because these have occurred before in Earth’s history.
In addition, paleontology has provided a fundamental contribution to human thought: the reality of species extinction and thus of a world that has dramatically changed over time. In documenting the history of life, paleontologists recognized that many extinction episodes could occur suddenly, such as the event 66 million years ago that ended the dinosaurs. The search for the causes of past mass extinctions started pioneering studies from across the scientific spectrum (科学界), focusing on potential future threats to humanity.
Not only do paleontologists know what happens to life when things go bad, they also know how long it takes for ecosystems and biodiversity to recover from these disasters, which can take far longer than modern humans have existed.
Paleontologists thus provide a unique perspective on the nature and future long-term ecological impact of the current human-produced biodiversity crisis, the so-called Sixth Extinction, and therefore the importance of protecting modern biodiversity. The very concept of a Sixth Extinction would not exist without paleontologists documenting the first five.
Paleontologists know that understanding life’s past is critical to anticipating and adapting to life’s and humanity’s future. Paleontology is important because it brings its unique and critical perspective to current challenges in climate change, biodiversity loss and the environment. Paleontologists can predict the future because they know the past.

4 . We usually think of archaeology as lots of painstaking work by brave explorers. But today, long-hidden cities are being revealed (显露) from the air, where modern archaeologists use laser pulses (激光脉冲) to discover the sign of ancient life buried below thick surface.
Lidar, short for “light detection and ranging”, needs directing rapid laser pulses at the ground from an airplane. Software catches the time and wavelength of the pulses reflected from the surface and connects it with GPS and other data to produce a precise 3D map of the landscape below.
In recent years, lidar exposed an ancient city in western Mexico called Angamuco. The discovery of this long-lost Mexican metropolis (大都) is especially meaningful.
“To think that this large city existed in the heartland of Mexico for all this time and nobody knew it was there is kind of amazing,” says Chris Fisher, an archaeologist at Colorado State University who led the expedition.
The city extended over ten square miles. “That is a huge area with a lot of people,” says Fisher. “You are talking about 40. 000 building foundations, which is about the same number of building foundations that are on the island of Manhattan.” Archaeologists were surprised when they saw Angamuco’s city plan. The monuments (纪念碑) were largely concentrated in eight zones around the edges rather than being located in one large center.
Archacologists discovered signs of the buried city in 2007 and attempted to explore it using a traditional way. But the team soon realized that it would take at least ten years to outline the whole metropolis. In 2011, they began using lidar to map nearly 14 square miles. Researchers now believe that more than 100. 000 people lived in Angamuco from about AD 1000 to AD 1350. That makes it the biggest city in western Mexico at the time or at least the biggest city we know about so far.
“Everywhere you point the lidar instrument, you find something new.” says Fisher. “Right now. every textbook has to be rewritten. and two years from now. they’re going to have to be rewritten again.”

6 . Back in 2019, three Chinese scientists were playfighting during a break from working in the Chongqing Province, China. One was kung-fu kicked into a rock, causing an opening in the rock face. Inside, a wonderful fossil (化石) lay undisturbed, preserved for millions of years.
The fossil was a jawed fish, some 439 million years old, and the findings from the Chongqing site, along with other fossil findings in nearby Guizhou province, have excited the science world, as they are 11 million years older than any fish fossil found before. It is a significant discovery because scientists have suspected that jaws evolved (进化) some 450 million years ago, but there had yet to be any fossils that supported this theory. The oldest fossils with jaws found were 439 million years old.
In this discovery, though, there was a new species of shark that was 439 million years old, with a full jaw.
“All these things are still like dreams,” said Zhu Min, who led the research teams that recently published four papers on the discoveries. “Today we are staring at complete early fishes, 11 million years earlier than the previous oldest finds. These are both the most exciting as well as the most challenging fossils I have had the privilege to work on.”
Some of the fish that were discovered were placoderms, an extinct class of fish that have hard plates that formed a shield around the head and trunk, while others were an ancient type of shark.
The scientists found the oldest-known teeth of any vertebrate (脊椎动物), 14 million years older than any previous findings, as well as two other shark descendants. China has been the site of numerous discoveries in recent years, including fossils of feathered dinosaurs, as well as the oldest known animals on Earth.
“The discovery of the Chongqing site is indeed an unbelievable miracle of fossil hunting,” Zhu added. “Suddenly we realized we have found a jaw-dropping fossil site. We are now close to the core of solving the fishy tree of early jawed vertebrates.”
