Enormous Maya Civilization Discovered, Complete With Roads, Reservoirs, And Ballcourts
Posted by Genevieve Klien in category: futurism
A previously unidentified Maya civilization made up of 964 interconnected settlements has been discovered in northern Guatemala. Dated to the Preclassic Maya period – which lasted from around 1,000 BCE until 150 CE – the scattered sites cover an area of approximately 1,685 square kilometers (650 square miles) and are linked by 177 kilometers (110 miles) of ancient roads.
Researchers spotted the network of settlements using LiDAR, a detection system that bounces laser signals off surfaces in order to reveal hidden features and structures. While flying over Guatemala’s Mirador-Calakmul Karst Basin (MCKB), the team utilized the technology in order to penetrate the thick jungle canopy and expose the ancient constructions lurking beneath.
“The LiDAR survey revealed an extraordinary density and distribution of Maya sites concentrated in the MCKB, many of them linked directly or indirectly by a vast causeway network,” write the researchers in a new study. In total, they found 775 sites within the MCKB itself, with a further 189 located in the surrounding karstic ridge.

Study identifies key neurons that maintain normal body temperature in mammals
Posted by Shubham Ghosh Roy in category: biotech/medical
A research group at Nagoya University in Japan has reported that a group of neurons, called EP3 neurons, in the preoptic area of the brain play a key role in regulating body temperature in mammals. The finding could pave the way for the development of a technology that artificially adjusts body temperature to help treat heat stroke, hypothermia, and even obesity. The new study was published in the journal Science Advances.
Body temperature in humans and many other mammals is regulated at about 37°C (98.6°F), which optimizes all regulatory functions. When body temperature noticeably deviates from the normal range, functions are impaired, which could lead to heat stroke, hypothermia, and, in the worst case, death. However, these conditions might be treated if body temperature can be artificially adjusted to the normal range.
The brain’s temperature regulation center resides in the preoptic area, a part of the hypothalamus that controls the body’s vital functions. For example, when the preoptic area receives signals from a mediator called prostaglandin E (PGE2) that is produced in response to infections, this area releases a command to raise body temperature to fight against viruses, bacteria, and other disease-causing organisms.

Compound semiconductors: Let there be light, speed and power
Posted by Omuterema Akhahenda in categories: business, quantum physics, robotics/AI
It now costs between $3bn-4bn to build a silicon chip fabrication plant (fab plant), and consequently, there are relatively few fabs around the world.-from 2019.
UK companies get ahead of the curve with investments in R&D and fabrication infrastructure for next-gen electronics. Andy Sellars, Chief Business Development Officer, UK Catapult, explains the strategy.
Artificial intelligence (AI) and quantum computing require compound semiconductors to achieve full commercialisation.
