Entrance to the Underworld

A hidden "entrance to the underworld" built by the ancient Zapotec culture has been discovered beneath a Catholic church in southern Mexico, according to a team of researchers using cutting-edge ground-scanning technology.
The complex system of underground chambers and tunnels was built more than a millennium ago by the Zapotec, whose state arose near modern-day Oaxaca in the late sixth century B.C. and grew in grandeur as people created monumental buildings and erected massive tombs filled with lavish grave goods.
The architectural complex at Mitla, 27 miles (44 kilometers) southeast of Oaxaca, boasts unique and intricate mosaics, having functioned as the main Zapotec religious center until the late 15th century, when the Aztec conquest likely resulted in the abandonment of the site. The Spanish then reused stone blocks from the ruins to build the San Pablo Apostol church a century later.
Oral histories have long suggested that the main altar of the church was purposefully built over a sealed entrance to a vast underground labyrinth of pillars and passages that originally belonged to a Zapotec temple known as Lyobaa, which means "the place of rest."
Investigating this claim with modern geophysical methods, the Project Lyobaa research team announced on May 12 that they had found a complex system of caves and passageways beneath the church. The project is a collaboration of 15 archaeologists, geophysical scientists, engineers and conservation experts with the Mexican National Institute of Anthropology and History (INAH), the National Autonomous University of Mexico, and the ARX Project.

Mayan Deity Statue
Archaeologists excavating construction sites along the new Maya Train route in Mexico have found a rare statue of the Mayan god K’awiil. The work is part of a recovery mission ahead of the railroad’s construction to ensure that the area’s ancient artifacts and monuments are not accidentally damaged.
The stone idol is dedicated to the Maya god of power, abundance, and prosperity, and is typically identified by his large eyes, upturned snout and a stone celt sticking out of his forehead.
Though this particular pre-Hispanic deity has more often been seen represented in paintings, relief sculpture, and the Dresden and Maya codices of Mexico, in this case his rare three-dimensional image was found on top of an urn.
“This finding is very important because there are few sculptural representations of the god K’awiil so far. We only know three in Tikal, Guatemala, and this is one of the first to appear in Mexican territory,” said Diego Prieto Hernández, general director of Mexico’s National Institute of Anthropology and History.
The discovery was made in section 7 of the Maya Train, an intercity railroad that loops around the Yucatán Peninsula and is expected to be completed next year. It has not been without its critics who say it is disruptive to the local environment, culture, and communities.
Other finds that have been made on the archaeologists’ previous rescue missions in sections 1-5 of the railroad include vessels, pottery fragments, bones, and the foundations of ancient structures belonging to Mesoamerican Mayan civilization. These objects are now being cleaned and classified in a dedicated lab in Chetumal.
“All this work should give rise to the analysis of the vast information, the preparation of academic reports and a great international research symposium on the Mayan civilization, which will be organized for this year,” said Prieto Hernández, who has also promised the construction of a new museum in Mérida to house the precious discoveries.

First Female President in Mexico
MEXICO CITY, Nov 3 (Reuters) - The most historic legacy of President Andres Manuel Lopez Obrador, a left-leaning resource nationalist who casts his administration as a turning point in the annals of Mexico, may be to pave the way for the country's first woman leader.
Mexico City Mayor Claudia Sheinbaum, a 60-year-old physicist, environmentalist and longstanding ally of Lopez Obrador who has governed as mayor in tandem with his presidency, has emerged as early front-runner to be his party's candidate in 2024, despite hints she could be more moderate than him.

The Founding Population of Mexico
Archaeologists have recovered DNA from 10 colonial-era inhabitants of Campeche, Mexico, revealing the diversity of the founding populations of European settlements in the Americas.
Campeche was an early colonial settlement in Yucatán. It was founded in 1540, less than 20 years after the Spanish conquest of the Aztecs, once conquistadors secured their rule.
The important port was initially served by a parish church until it was replaced by a cathedral in 1680. The church was rediscovered in 2000 during rescue excavations when archaeologists found 129 early colonial burials at the site.
Early attempts to extract DNA from these burials failed. Now advances in aDNA research have allowed Professor Vera Tiesler and a team of researchers from Harvard University to gather genetic data from this important site. Their work is published in the journal Antiquity.
“Ancient DNA methods have improved to the point where we can generate robust data from warm, humid environments,” said Dr Jakob Sedig, from the Reich Laboratory at Harvard University and co-lead author of the research, “Using the petrous bone, we were able to generate excellent data from all 10 individuals we tested, which is encouraging for future ancient DNA analysis in this region.”
The aDNA revealed the 10 individuals interred in the colonial cemetery were made up of six females and four males, and none were close relatives. Most were local Indigenous Americans, but people of European and sub-Saharan African ancestry were also identified. READ MORE...

Mexico Blames US
"Poverty and desperation" led to the deaths of at least 50 migrants abandoned in a Texas lorry, Mexico's president has said.
Andres Manuel Lopez Obrador blamed trafficking and "a lack of control" at the border - the worst case of migrant deaths due to smuggling in the US.
Nearly two dozen Mexicans, seven Guatemalans and two Hondurans were among the dead.
Those found alive, including four children, were taken to hospital.
The survivors were "hot to the touch" and suffering from heat stroke and heat exhaustion.
So far, Mexican authorities have said that at least two Mexican citizens are being treated for dehydration in hospital. Consular officials are working to confirm their identities.
Authorities are working to confirm the nationalities of remaining victims.
According to US authorities, three people "believed to be part of the smuggling conspiracy" have been taken into custody.
Speaking at his daily briefing, Mr Lopez Obrador, popularly known as Amlo, called the discovery a "tremendous tragedy", and said Mexico would work to repatriate the remains of its citizens. READ MORE...

Mayan City Discovered
The style of architecture of the buildings at Xiol is more typical of the style
found in regions further south
Archaeologists working in the Yucatan region of Mexico have revealed the remains of a centuries-old Mayan city, local media reported on Friday.
The city of Xiol — which means "the spirit of man" in Mayan — is believed to have been the home of some 4,000 people between 600 and 900 CE, during the late classic period.
The area was first uncovered in 2018 on a construction site for a future industrial park close to the town of Merida on Yucatan's northern coast. Archaeologists from the National Institute for Anthropology and History (INAH) then took over the site.
The Mayan civilization was destroyed by Spanish colonizers in the 17th century
Palaces, priests, pyramids
The site is of particular interest due to its Puuc style architecture — famously used for the Chichen Itza pyramid — which is more typically found in the southern part of the Yucatan region.
The archaeologists also highlighted the array of palaces, pyramids and plazas found at the site as well as evidence of various social classes residing there.
"There were people from different social classes ... priests, scribes, who lived in these great palaces, and there were also the common people who lived in small buildings," Carlos Peraza, one of the archaeologists leading the excavations, said. READ MORE...

Interior of Protons Entangled
If a photon carries too little energy, it does not fit inside a proton (left). A photon with sufficiently high energy is so small that it flies into the interior of a proton, where it 'sees' part of the proton (right). Maximum entanglement then becomes visible between the 'seen' and 'unseen' areas. Credit: IFJ PAN
Fragments of the interior of a proton have been shown by scientists from Mexico and Poland to exhibit maximum quantum entanglement. The discovery, already confronted with experimental data, allows us to suppose that in some respects the physics of the inside of a proton may have much in common not only with well-known thermodynamic phenomena, but even with the physics of... black holes.
Various fragments of the inside of a proton must be maximally entangled with each other, otherwise theoretical predictions would not agree with the data collected in experiments, it was shown in European Physical Journal C.
The theoretical model (which extends the original proposal by physicists Dimitri Kharzeev and Eugene Levin) makes it possible to suppose that, contrary to current belief, the physics operating inside protons may be related to such concepts as entropy or temperature, which in turn may relate it to such exotic objects as black holes.
The authors of the discovery are Dr. Martin Hentschinski from the Universidad de las Americas Puebla in Mexico and Dr. Krzysztof Kutak from the Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ PAN) in Cracow, Poland.
The Mexican-Polish theorists analyzed the situation in which electrons are fired at protons. When an incoming electron carrying a negative electric charge approaches a positively charged proton, it interacts with it electromagnetically and deflects its path.

Electromagnetic interaction means that a photon has been exchanged between the electron and the proton. The stronger the interaction, the greater the change in momentum of the photon and therefore the shorter the associated electromagnetic wave. READ MORE...

The Mayans
A research team from students at Brown University and Brandeis University surveyed a small area in the Western Maya Lowlands.
It sits on the border between Mexico and Guatemala where the Maya people were thought to have lived around 350 AD and 900 AD. It was previously believed that the Maya were people who engaged in “unchecked agricultural development”.
Andrew Scherer, an associate professor of anthropology, said that “The narrative goes – the population grew too large, the agriculture scaled up, and then everything fell apart.”
But now, the researchers found using a lidar survey — and, later from on the ground surveying, that there were extensive systems of sophisticated irrigation and terracing in and outside the region’s towns, but no huge population booms to match.
This showed that between 350 AD and 900 AD, some Maya kingdoms were living comfortably, with sustainable agricultural systems and no demonstrated food insecurity.
Mr Scherer said: “It’s exciting to talk about the really large populations that the Maya maintained in some places, to survive for so long with such density was a testament to their technological accomplishments. READ MORE...

Aztec Empire Spirit Mirror

The 16th-century courtier John Dee, a scientific adviser to England's Queen Elizabeth I, was also deeply involved in magic and the occult, and he tried to commune with ghosts, using a so-called spirit mirror made of polished obsidian.
Now, a new analysis of Dee's infamous mirror has finally traced its origins — not to the spirit world, but to the Aztec Empire.
Obsidian mirrors such as Dee's were known from Aztec culture, but there were no records on his mirror's origins. However, geochemical analysis enabled researchers to link the mirror's obsidian — a type of volcanic glass — to Pachuca, Mexico, a popular source of obsidian for Aztec people. This finding indicated that the artifact was Aztec and not a copy made from European obsidian, and Dee likely acquired the mirror after it was brought to Europe from Mexico, according to a new study.
Though Dee was a scientist and mathematician, his interests also swung toward the magical and mystical, and in addition to the spirit mirror, he owned other objects related to astrology, divination, alchemy and the exploration of "demonic magic," scientists reported Oct. 7 in the journal Antiquity.
Dee claimed that one of these objects, a purple crystal on a chain, was given to him by the archangel Uriel, along with instructions for making a philosopher's stone — the mythical alchemical marvel that promised the gift of eternal life and the ability to turn base metals into gold, according to the Royal College of Physicians (RCP) in London. Dee also possessed a Claude glass, a black glass mirror kept in a sharkskin case, which he used for "peering into the future," according to the RCP.
Dee's obsidian mirror, now in the collection of the British Museum in London, is polished on both sides and is nearly perfectly circular, measuring about 7.2 inches (18.5 centimeters) in diameter and 0.5 inches (13 mm) thick, and weighing about 31 ounces (882 grams). A perforated square tab at the top of the mirror measures about 1.3 inches (33 mm) long and may have served as a handle, according to the study. READ MORE...

Swapping Statues
The statue was daubed with paint during protests last year |
A statue of Italian explorer Christopher Columbus, which stood on one of the main avenues of Mexico City, will be replaced by one of an indigenous woman.
Mexico City Mayor Claudia Sheinbaum said the bronze likeness of Columbus would be moved to a park and a statue of an Olmec woman would take its place.
The Columbus statue was removed from its plinth last year ahead of protests. Protesters have toppled Columbus statues in Latin America and the US.
Christopher Columbus, an Italian-born explorer who was financed by the Spanish crown to set sail on voyages of exploration in the late 15th Century, is seen by many as a symbol of oppression and colonialism as his arrival in America opened the door to the Spanish conquest.
Mayor Sheinbaum made the announcement on Sunday at a ceremony marking the international day of the indigenous woman. She said that relocating the statue was not an attempt to "erase history" but to deliver "social justice".
Ms Sheinbaum said that the Columbus statue "would not be hidden away" but that the civilisations which existed in Mexico before the Spanish conquest should receive recognition. READ MORE

Increase in Diabetes
Diabetes surged among American children, teens and adolescents to 2017, according to new federally-funded research spanning nearly 20 years finding a 45% increase in type 1 diagnoses, and a 95% growth in type 2 diagnoses.
"Increases in diabetes are always troubling – especially in youth. Rising rates of diabetes, particularly type 2 diabetes, which is preventable, has the potential to create a cascade of poor health outcomes," Dr. Giuseppina Imperatore, chief of the Surveillance,
Epidemiology, Economics, and Statistics Branch in CDC’s Division of Diabetes Translation, said in a statement issued Tuesday. "Compared to people who develop diabetes in adulthood, youth are more likely to develop diabetes complications at an earlier age and are at higher risk of premature death."
Findings published in JAMA on Tuesday indicated that Type 1 diabetes persists as the most common type of diabetes among U.S. youth. Results stemmed from an average of 3.5 million Americans under age 20 studied on a yearly basis from 2001 to 2017 across areas of California, Colorado, Ohio, South Carolina, Washington State, Arizona and Mexico.

Results stemmed from an average of 3.5 million Americans under age 20 studied on a yearly basis from 2001 to 2017 across areas of California, Colorado, Ohio, South Carolina, Washington State, Arizona and Mexico.
Results indicated significant increases in type 1 diabetes among Americans 19 years or younger, from 1.48 per 1,000 young people to 2.15 per 1,000 by 2017, or a 45% increase over 16 years, whereas the prevalence of type 2 diabetes among kids aged 10-19 increased from 0.34 per 1,000 youths to 0.67 per 1,000 youths, or a 95.3% increase over 16 years.
Study authors noted no significant differences in the increases in diabetes prevalence across sexes.
The study found the largest increases in type 2 diabetes were among Black and Hispanic youth, with increases in the estimated prevalence of type 1 diabetes greatest among Black and White youths. Kids under age 9 with type 2 diabetes were excluded from the study due to small sample sizes.
Diabetes is a chronic health condition impacting how the body converts food into energy. According to the Centers for Disease Control and Prevention (CDC), "If you have diabetes, your body either doesn’t make enough insulin or can’t use the insulin it makes as well as it should. When there isn’t enough insulin or cells stop responding to insulin, too much blood sugar stays in your bloodstream. Over time, that can cause serious health problems, such as heart disease, vision loss, and kidney disease." READ MORE
