A tetraplegic capable of writing with his mind with brain chips

The typing speed of a spinal cord injured was close to that of other people typing on their mobile. Sensors in the brain of a tetraplegic have captured neural activity while imagining that he was writing and have converted it, letter by letter, into text. This brain-computer interface (BCI) has achieved a writing speed close to that of anybody while typing on a mobile phone…

A robot that builds the walls of a house in one day

This robot, called Hadrian X, is an invention of the Australian company Fast Brick Robotics (FBR) They created the first prototype in 2005. After a time of doubts and issues, Hadrian X's precursor arrived. Its name was Hadrian 105 and, in 2016, it built the first block structure from a 3D CAD model. In 2017, a contract with the Kingdom of Saudi Arabia to build 50,000 houses was the definitive push for this project. And in 2018, this robot was already a reality…

Scientists create hybrid human and monkey embryos, which may help 'build' organs for transplantation and study cancer and ageing

The experiment makes it possible to advance in the knowledge of the first stages of pregnancy and paves the way for obtaining, in the future, organs for transplantation in animals. An international team of researchers, led by the Spanish Juan Carlos Izpisúa, from the Salk Institute in the United States, and with the collaboration of the Kunming University of Science and Technology in Yunnan, China (led by Weizhi Ji), has generated hybrid human and macaque embryos in the laboratory…

Philippine students need to plant 10 trees to graduate

To regain its forest cover and see forests grow again, the Philippines introduced an interesting law that requires each student to plant 10 trees before graduation. Deforestation constitutes one of the great global problems, constituting a serious threat to existing biodiversity, a decrease in the absorption capacity of CO2, and the loss of habitat for millions of animal and plant species…

Artificial intelligence now allows us to recover lost languages

An artificial intelligence system developed by the MIT Laboratory of Computer Science and Artificial Intelligence (CSAIL) aims to decipher missing languages and learn more about the people who spoke them. The algorithms they have designed can automatically decipher a lost language using only a few thousand words (far less data than is commonly used to train algorithms). The records that have survived to our days of the languages ??that have been lost throughout history are so minimal (often la…
