Talking heads: what toilets and sewers tell us about ancient Roman sanitation

Reading time: 9 minutes
Focusing on life in ancient Rome, Pompeii, Herculaneum and Ostia, I’m deeply impressed by the brilliant engineers who designed these underground marvels and the magnificent architecture that masks their functional purpose. Sewer galleries didn’t run under every street, nor service every area. But in some cities, including Rome itself, the length and breadth of the main sewer, the Cloaca Maxima, rivals the extent of the main sewer lines in many of today’s cities. We shouldn’t assume, though, that Roman toilets, sewers and water systems were constructed with our same modern sanitary goals in mind.

Our stone tool discovery pushes back the archaeological record by 700,000 years

Reading time: 8 minutes
We, and the West Turkana Archaeological Project which we co-lead, had discovered the earliest stone artifacts yet found, dating to 3.3 million years ago. The discovery of the site, named Lomekwi 3, instantly pushed back the beginning of the archaeological record by 700,000 years. That’s over a quarter of humanity’s previously known material cultural history. These tools were made as much as a million years before the earliest known fossils attributed to our own genus, Homo.

What stone tools found in southern tip of Africa tell us about the human story

Reading time: 6 minutes
Stone tools. Our ancestors made them, some people still make them, and many species of extinct humans made them too. For more than three million years, fractured pieces of hard rock provided past people with a means to extract their livelihood from the environment. Because stone is plentiful and cheap to acquire, stone tools were made in large numbers. And because it is so durable, it usually outlasts other traces of human activity. With the passing of time, everything from our thoughts and languages to clothes, food waste and even our own bones are inevitably erased. But stone tools have remained.

Scans reveal new details of how Egyptian pharaoh met a violent death

Reading time: 4 minutes
For Seqenenre Taa II, the violent injuries were possibly the result of dying in battle or execution by a king who had invaded the north of the country. One theory also suggested he was killed while sleeping. In the new study, the team applied computed tomography (CT) scanning to the remains to investigate further. CT is a non-invasive imaging method that basically layers multiple X-rays on top of each other in order to create three dimensional images of both the soft and hard tissues. We usually think of it in clinical settings, but it has a long history of use in forensic contexts to safely study remains contained inside wrappings or body bags.

Scientists at work: Public archaeologists dig before the construction crews do

Reading time: 8 minutes
I’m the director of the Public Archaeology Facility, a research center specializing in cultural resource management. Our mission is to identify, evaluate and preserve significant sites, train students to be professional archaeologists and share our results with the public. We can work on up to 100 projects a year. Since our inception in 1972, the center has discovered more than 3,500 archaeological sites.

Glastonbury: archaeology is revealing new truths about the origins of British Christianity

Reading time: 5 minutes
Many Christians believe that Glastonbury is the site of the earliest church in Britain, allegedly founded in the first or second century by Joseph of Arimathea. According to the Gospels, Joseph was the man who donated his own tomb for the body of Christ following the crucifixion. By the 14th century, it was popularly believed that Glastonbury Abbey had been founded by the biblical figure of Joseph. The legend emerged that Joseph had travelled to Britain with the Grail, the vessel used to collect Christ’s blood. For 800 years, Glastonbury has been associated with the romance of King Arthur, the Holy Grail and Joseph of Arimathea. Later stories connected Glastonbury directly to the life of Christ.

DNA from elusive human relatives the Denisovans has left a curious mark on modern people in New Guinea

Reading time: 5 minutes
An encounter with a mysterious and extinct human relative – the Denisovans – has left a mark on the immune traits of modern Papuans, in particular those living on New Guinea Island. This is a new discovery we describe in a study published in PLoS Genetics today. It further suggests that our modern human diversity didn’t just evolve – some parts of it we got from other, extinct human groups.

Cracking the Code: The Quest to Decipher the Indus Valley Script

Reading time: 5 minutes
The Rosetta Stone laid the groundwork for our understanding of Ancient Egyptian language and culture when French scholar Jean-François Champollion cracked its code in September 1822. But the Rosetta Stone isn’t the only unsolved puzzle out there. Since the discovery of the Indus Valley Civilisation in the 1920s, the Indus Valley Script has remained an enigma, resisting all attempts at decipherment. From the origins of the civilisation to the reasons why the script remains undecoded, and what the future may hold, unlocking the Indus Valley Script could reveal important insights into one of history’s great ancient cultures.

We have revealed a unique time capsule of Australia’s first coastal people from 50,000 years ago

Reading time: 5 minutes
Barrow Island, located 60 kilometres off the Pilbara in Western Australia, was once a hill overlooking an expansive coast. This was the northwestern shelf of the Australian continent, now permanently submerged by the ocean.
Our new research, published in Quaternary Science Reviews, shows that Aboriginal people repeatedly lived on portions of this coastal plateau. We have worked closely with coastal Thalanyji Traditional Owners on this island work and also on their sites from the mainland.
