Scientists Accidentally Discover Ancient Hepatitis B in a 16th-Century Mummy

Since the 1980s, a child mummy buried in the Basilica of Saint Domenico Maggiore in Naples, Italy in the 16th century has been known as the earliest recorded case of smallpox in the world. The problem is, the 2-year-old didn’t have smallpox, according to new research spotted by IFLScience. But, as the scientists reexamining the remains discovered, it’s still a landmark study in disease evolution. It appears to be the earliest instance of hepatitis B that researchers have ever found in Italy, giving scientists insight into how the virus has evolved over the last several centuries.

The hepatitis B virus (HBV) attacks the liver and can result in cirrhosis and liver cancer, killing around 887,000 people per year. Though it can now be largely prevented by a vaccine, the World Health Organization estimates that 257 million people around the world live with HBV. It often affects children, spreading from mother to child during birth.

For the current study published in PLOS Pathogens, a team of researchers from McMaster University in Canada set about studying the child mummy with the hopes of continuing their past work nailing down how smallpox spread and evolved over human history. But when they used molecular analysis to study the mummy’s skin and bones, they didn’t find anything that indicated that the toddler had smallpox. Instead, they found the hepatitis B virus—which can cause a rash called Gianotti-Crosti Syndrome that the original researchers studying the mummy may have mistaken for the telltale rash associated with smallpox.

The ancient HBV strain found in the mummy's tissues had a genome closely related to that of the modern virus, which, The New York Times explains, could very well mean that the mummy was contaminated when it was first studied in the 1980s. But after analyzing the genetic material further and studying other examples of older HBV strains, they found that it’s plausible that the virus just hasn’t evolved extensively in the past 500 years. Though the contamination theory is still possible, it’s more likely that the mummy really does carry an ancient version of the virus. Considering that HBV has also been traced back to the 16th century in Asia, it’s likely that Europeans were suffering from it around the same time.

Demolition of a Condemned Pennsylvania Bar Reveals 18th-Century Log Cabin

Many unusual things have been discovered in the structures of old buildings. When contractors began demolishing a bar in Washingtonville, Pennsylvania, they didn't expect to find a separate building concealed within its paneling.

The log cabin uncovered in the bar was built as far back as the 18th century, Newsweek reports. Contractors were in the process of tearing down the condemned establishment when they noticed antique, exposed beams inside the building additions. As they removed more panels, a whole log cabin began to take shape.

The structure consists of two stories and spans 1200 square feet. The beams appear to be made of ax-cut hickory wood, but beyond that, little is known about the cabin or where it came from. A borough map from 1860 depicts a larger building where the cabin would be, indicating that the first additions were built onto it more than 150 years ago. The bar built at the site has been closed for around 12 years and condemned for more than three.

Washingtonville council president Frank Dombroski says the cabin is salvageable, but taking the necessary steps to preserve it will be difficult. The community lacks the funds necessary to rehabilitate it where it stands and keep it as a historic landmark. Instead, the council has decided to disassemble the structure piece-by-piece, number and catalog it, and reconstruct it someplace else. Until then, the building in its exposed state will remain in its original location on the corner of Water and Front Streets.

Ancient Human Remains Were Found During a Father-Son Bike Trip in Washington

Among the things you can expect from a leisurely bike ride with your 4-year-old son—fresh air, exercise, bonding—accidentally stumbling upon ancient human remains is not among them. Yet that’s exactly what happened to Matt Kiddle earlier this month near Port Angeles, Washington, when a spin around the area revealed a weathered skull erupting from the ground.

Kiddle was biking with his son, Ivan, along the Olympic Discovery Trail when the two came across the skull and mandible. The pair climbed off his bike and walked on to the beach for a closer look, where Kiddle also noticed a scapula, or shoulder blade. Later, another pedestrian noticed a hip bone.

Fearing they had stumbled upon a crime scene, Kiddle examined the remains and realized the bones were likely old. He called the police. A forensic archaeologist determined they’re between 500 and 1000 years old and are of Native-American origin.

"Frankly, my first reaction was, what poor individual is missing that I just found their bones, then I quickly realized they were very old and likely Native American, and some form of ancient individual," Kiddle, a physician assistant, told the Peninsula Daily News.

How did the remains manage to become visible? Parts of the Trail have crumbled due to coastal erosion, revealing below-surface discoveries like this one.

The Washington Department of Archaeological and Historic Preservation will now look to determine which tribe the deceased belonged to so the bones can be repatriated and properly laid to rest.
