Bodies of 800 Children Uncovered in English Burial Ground

During an exhumation at St. Peter's Burial Ground in the town of Blackburn in Lancashire, England, archaeologists uncovered 1967 bodies that date back to the 19th century, 800 of which were children aged six years and under.

BBC reports that the exhumation was scheduled ahead of the construction of a new road. A spokeswoman for the Darwen Borough Council said that St. Peter's Burial Ground, which opened in 1821, saw "intense use" up to the 1860s, and that the section of the burial ground where the bodies were found represents 30 percent of the site. The children were found buried with coins from 1821, as well as pieces of glass bead jewelry.

Headland Archaeology, the team handling the removal of the bodies, said that analysis of the remains is still in its early stages, but they believe that the children died from infections to their lungs and guts. "They would have died quite quickly so the signs may not turn up in their skeletons," an expert with Headland, Dave Henderson, said, adding that the population "grew very quickly" at the time and that overcrowding played a factor in the living conditions.

Going into the project, the archaeologists only expected about 200 graves, but discovered twice as many, and some were filled with the remains of multiple people. "One grave had 13 bodies in it," councillor Phil Riley said. "It shows the poverty and poor health of the people before the introduction of clean water and the terrible level of infant mortality." The cemetery was in use until 1945. The church it was attached to was razed in 1976.

Whale Sharks Can Live for More Than a Century, Study Finds

Some whale sharks alive today have been swimming around since the Gilded Age. The animals—the largest fish in the ocean—can live as long as 130 years, according to a new study in the journal Marine and Freshwater Research. To give you an idea of how long that is, in 1888, Grover Cleveland was finishing up his first presidential term, Thomas Edison had just started selling his first light bulbs, and the U.S. only had 38 states.

To determine whale sharks' longevity, researchers from the Nova Southeastern University in Florida and the Maldives Whale Shark Research Program tracked male sharks around South Ari Atoll in the Maldives over the course of 10 years, calculating their sizes as they came back to the area over and over again. The scientists identified sharks that returned to the atoll every few years by their distinctive spot patterns, estimating their body lengths with lasers, tape, and visually to try to get the most accurate idea of their sizes.

Using these measurements and data on whale shark growth patterns, the researchers were able to determine that male whale sharks tend to reach maturity around 25 years old and live until they’re about 130 years old. During those decades, they reach an average length of 61.7 feet—about as long as a bowling lane.

While whale sharks are known as gentle giants, they’re difficult to study, and scientists still don’t know a ton about them. They’re considered endangered, making any information we can gather about them important. And this is the first time scientists have been able to accurately measure live, swimming whale sharks.

“Up to now, such aging and growth research has required obtaining vertebrae from dead whale sharks and counting growth rings, analogous to counting tree rings, to determine age,” first author Cameron Perry said in a press statement. ”Our work shows that we can obtain age and growth information without relying on dead sharks captured in fisheries. That is a big deal.”

Though whale sharks appear to be quite long-lived, their lifespan is short compared to the Greenland shark's—in 2016, researchers reported they may live for 400 years. 

Scientists Find a Possible Link Between Beef Jerky and Mania

Scientist have discovered a surprising new factor that may contribute to mania: meat sticks. As NBC News reports, processed meats containing nitrates, like jerky and some cold cuts, may provoke symptoms of mental illness.

For a new study, published in the journal Molecular Psychiatry, scientists surveyed roughly 1100 people with psychiatric disorders who were admitted into the Sheppard Pratt Health System in Baltimore between 2007 and 2017. They had initially set out to find whether there was any connection between certain infectious diseases and mania, a common symptom of bipolar disorder that can include racing thoughts, intense euphoria, and irritability.

While questioning participants about their diet, the researchers discovered that a significant number of them had eaten cured meats before their manic episodes. Patients who had recently consumed products like salami, jerky, and dried meat sticks were more likely to be hospitalized for mania than subjects in the control group.

The link can be narrowed down to nitrates, which are preservatives added to many types of cured meats. In a later part of the study, rats that were fed nitrate-free jerky acted less hyperactive than those who were given meat with nitrates.

Numerous studies have been published on the risks of consuming foods pumped full of nitrates: The ingredient can lead to the formation of carcinogens, and it can react in the gut in a way that promotes inflammation. It's possible that inflammation from nitrates can trigger mania in people who are already susceptible to it, but scientists aren't sure how this process might work. More research still needs to be done on the relationship between gut health and mental health before people with psychiatric disorders are told to avoid beef jerky altogether.
