(Press-News.org) For sports fans, places like Fenway Park, Wembley Stadium or Wimbledon's Centre Court are practically hallowed ground.
Archaeologists at the University of Cincinnati found evidence of similar reverence at ballcourts built by the ancient Maya in Mexico.
Using environmental DNA analysis, researchers were able to identify a collection of plants used in ceremonial rituals in the ancient Maya city of Yaxnohcah. The plants, known for their religious associations and medicinal properties, were discovered beneath a plaza floor upon which a ballcourt was built.
Researchers said the ancient Maya likely made a ceremonial offering during the ballcourt’s construction.
“When they erected a new building, they asked the goodwill of the gods to protect the people inhabiting it,” UC Professor David Lentz said. “Some people call it an ensouling ritual, to get a blessing from and appease the gods.”
The study was published in the journal PLOS ONE.
The research was carried out through Mexico's National Institute of Anthropology and History in collaboration with researchers from the University of Calgary, the Autonomous University of Campeche and the National Autonomous University of Mexico.
Researchers from 2016 to 2022 worked at Yaxnohcah in Campeche about 9 miles north of the border of Guatemala, where they excavated a small area of a ballcourt.
The ancient Maya played several ball games, including pok-a-tok, which has rules similar to soccer and basketball. Players tried to get a ball through a ring or hoop on a wall.
UC Professor Emeritus Nicholas Dunning said when buildings were expanded or repurposed, as with the ballcourt, the ancient Maya made offerings to bless the site. Archaeologists sometimes find ceramics or jewelry in these offerings along with plants of cultural significance.
“We have known for years from ethnohistorical sources that the Maya also used perishable materials in these offerings, but it is almost impossible to find them archaeologically, which is what makes this discovery using eDNA so extraordinary,” Dunning said.
Ancient plant remains are rarely discovered in tropical climates, where they decompose quickly. But using environmental DNA, researchers were able to identify several types known for their ritual significance.
They discovered evidence of a morning glory called xtabentun, known for its hallucinogenic properties, lancewood, chili peppers and jool, the leaves of which were used to wrap ceremonial offerings.
Botanist and UC Associate Professor Eric Tepe said finding evidence of these plants together in the same tiny sediment sample is telling. He has studied modern plants in the same forests once traveled by the ancient Maya.
“I think the fact that these four plants which have a known cultural importance to the Maya were found in a concentrated sample tells us it was an intentional and purposeful collection under this platform,” Tepe said.
Researchers noted the challenge of trying to interpret a collection of plants through the opaque lens of 2,000 years of prehistory. But Lentz said the findings help add to the story of this sophisticated culture.
Researchers believe the ancient Maya devised water filtration systems and employed conservation-minded forestry practices. But they were helpless against years-long droughts and also are believed to have deforested vast tracts for agriculture.
“We see the yin and yang of human existence in the ancient Maya,” Lentz said. “To me that’s why they’re so fascinating.”

SCN2A related-disorders, although rare in the general population, are one of the more common single-gene neurodevelopmental conditions characterized by infantile seizures, autism spectrum disorder and intellectual disabilities
Severity of these disorders varies widely from person to person
Findings should help better identify patients who are most appropriate for clinical trials of new precision medicines and gene therapies
CHICAGO --- A genetic change or variant in a gene called SCN2A is a known cause of infantile seizures, autism spectrum disorder and intellectual disability, as well as a wide range of other moderate-to-profound impairments in mobility, ...
OHSU study finds big jump in addiction treatment at community health clinics
2024-04-26
The number of health care professionals able to write a prescription for a key medication to treat addiction quadrupled at community health clinics from 2016 to 2021, according to a new study by researchers at Oregon Health & Science University.
The findings, published online today in the journal JAMA Health Forum, provides a glimmer of hope amid a national overdose epidemic that has claimed more than 100,000 lives in the United States in each of the past few years.
The study examined community health centers serving low-income people primarily in West Coast states. Researchers ...

Riverside, Calif. -- In unincorporated communities in the United States-Mexico borderlands, historically and socially marginalized populations become invisible to the healthcare system, showing that geography acts as a structural determinant of health for low-income populations. So concludes a study by a University of California, Riverside, team that focused its attention on the borderland in Southern California, specifically, eastern Coachella Valley.
From September to December 2020, the team, led by Ann Cheney, an associate professor of social medicine, population, and public health in the School of Medicine, conducted interviews in collaboration with ...
