The existence of an ancient Mayan palace more than 1000 years old in the Mexican jungle has been confirmed

Published

A palace built by the ancient Mayan civilization more than 1000 years old that was found in the middle of the jungle in the northeast of the Yucatan Peninsula, Mexico, according to a statement by the National Institute of Anthropology and History of Mexico.

The palace, which is part of a complex that is probably much larger and which also sees the presence of a burial site, was built by the inhabitants of Kulubá, an ancient Mayan city. According to Mexican archaeologists, this palace must have been in use between 600 and 1050 AD. The palace is characterized by a length of 55 meters, a width of 15 meters and a height of 6 meters.

The discovery may offer a lot of data and information about the architectural style of the Kulubá civilization, of which very little is known. Archaeologists themselves believe that by digging further, more structures can be found, so that this site will most likely become an attraction for visitors.

The Mayan civilization, in fact, used to build temples and pyramids as well as huge stone buildings. However, it suffered a mysterious decline between 800 and 1000 A.D., decline whose houses have never been fully clarified (various hypotheses speak of intestinal wars, climatological upheavals and viral diseases).

A new species of turtle in Texas that lived almost 100 million years ago has been classified

Published

on

Analyzing the remains found at the Arlington Archosaur Site, a site with various fossil remains from the late Cretaceous period in Texas, a team of researchers described four species of extinct turtles, one of which is named after paleontologist Derek Main.

This site was discovered in 2003 and proved to be a prolific location for late Cretaceous remains, remnants of life forms that lived more than 90 million years ago. It is a wetland located near the shore of a peninsula and already in the past has provided several fossils of ancient crocodiles, dinosaurs, mammals, amphibians, fish, invertebrates and even plants.

However, the turtle fossils discovered at this site had proved quite rare, at least until this study that was published in Palaeontology Electronica. The new species was named Trinitichelys maini. It is a Baenidae turtle, an extinct group of North American aquatic turtles that lived from the Cretaceous to the Eocene era.

Of medium size, these turtles showed strongly fused bones and upper shell and lived near rivers. The Trinitichelys maini is the oldest turtle of this group found in the North American subcontinent of Appalachia, a region that during the Cretaceous period was separated from Laramidia, the western subcontinent of North America.

In addition to the new classification, researchers described three other turtles, one of which is the oldest side-necked turtle (Pleurodira order) ever found in North America. These turtles are characterized by the particular way they withdraw their heads inside their shells: they do so by bending their necks on the horizontal plane.

The other two turtles described are one belonging to the group of trionichids (Trionychidae), or soft-shelled turtles, and another belonging to the genus Naomichelys (family Helochelydridae ).

Key mechanism of epilepsy in Angelman syndrome discovered by researchers

Published

on

In the course of research defined as “innovative,” a team of researchers from the Duke-NUS Medical School and the National Neuroscience Institute (NNI), Singapore, discovered a mechanism considered to be basic with regard to epilepsy in Angelman syndrome. This discovery, according to the researchers themselves, could lead to new therapies in the future.

Angelman’s syndrome (AS) is a rare genetic disease due to a defect in the process of chromosome duplication, often accompanied by delays in psychological and motor development, cognitive disabilities and other symptoms including epilepsy. In the course of the study, researchers at the Singapore Institutes used a new experimental methodology with human neural cells and brain organelles to understand the mechanism of epileptic seizures in this syndrome.

The researchers discovered the role of the ion channel in the hyperactivity of the brain network that triggers convulsions. The latter would be linked to gene deficiency of the ubiquitin ligase protein E3A (UBE3A) within neurons. As this is a syndrome that cannot be treated at present, this discovery could, therefore, be very important.

“Our study used 2D human neuronal cultures that allowed the accelerated discovery of functional differences at the single-cell level in the brain of normal individuals compared to those with AS,” explains Hyunsoo Shawn Je, the senior author of the study. “The use of mini 3D human brains allowed us to monitor spontaneous network activities, linking the results of abnormal firing from individual neurons and convulsive-like activities, just like those observed in the brains of AS patients.”

Psilocybin produced by Escherichia coli modified with magic mushroom genes

Published

on

A team of researchers at Miami University in Ohio has managed to engineer Escherichia coli bacteria to produce psilocybin, a psychedelic substance usually produced by so-called “magic mushrooms” and which in recent years is proving increasingly interesting in the treatment of people suffering from depression or other mental illnesses such as addiction.

Since mushroom cultivation can be quite difficult and can take months, it has never proved to be very practical for the production of drugs. On the other hand, the synthetic production of psilocybin itself is equally difficult and the process is very expensive. The researchers have therefore thought of modifying these microbes so that they can generate up to 1.16 grams of psilocybin per litre of culture medium. This is the highest yield to date for engineered microorganisms producing this substance and opens the door to more widespread therapeutic use.

They have in particular ensured that the Escherichia coli bacteria incorporated three genes of the fungus Psilocybe cubensis. In this way the bacteria began to synthesize psilocybin from the 4-hydroxyindol molecule.

As Alexandra Adams, a chemical engineering student at the above mentioned university and one of the authors of the study published in Scientific American, explains, the main advantage of this procedure is that it is much cheaper than all the other methods.

Currently the only limit is represented by the danger that these bacteria could also generate toxic or allergenic microbial material and the latter must be absolutely removed before any possible use of the resulting psilocybin but in any case the results seem impressive.
