What has baffled humanity today is shocking mechanics built in the AI machines and tools. Altogether they are gradually replacing the work and skills carried out by humans for generations. By 2030, almost 47 per cent of the jobs that face high risks of automation would be taken over by AI. The loss of  man-controlled jobs would add woes to the economic plight  The arrival of Artificial Intelligence (AI) has dramatically changed our lives. Globalisation criss-crossing the globe has pushed human civilisation to new frontiers of change. And one of the most remarkable dynamics heralded by the forces of such…

The James Webb Space Telescope has made the first clear detection of carbon dioxide in the atmosphere of a distant world, and there is also an unexpected bump in the data NASA’s James Webb Space Telescope (JWST) has spotted carbon dioxide in the atmosphere of a planet 700 light years away called WASP-39b. This is the first time the compound has been found in any exoplanet, and the observations also revealed hints of a mystery within the distant world. WASP-39b is huge. It has a mass similar to Saturn’s, anda diameter 1.3 times that of Jupiter. It orbits relatively close to its…

The nervous and immune systems are tightly intertwined. Deciphering their chatter might help address many brain disorders and diseases. University in St. Louis   The brain is the body’s sovereign, and receives protection in keeping with its high status. Its cells are long-lived and shelter inside a fearsome fortification called the blood–brain barrier. For a long time, scientists thought that the brain was completely cut off from the chaos of the rest of the body — especially its eager defence system, a mass of immune cells that battle infections and whose actions could threaten a ruler caught in the crossfire.…

Facebook’s parent company, Meta, has used AI to develop a new way of creating concrete which it claims produces 40 per cent less carbon emissions than standard mixtures, and is already using it in its latest data centre. But experts say that concrete mixtures with similar emissions are already in use across Europe, and that constructing new buildings is incompatible with reducing carbon pollution. Meta is investing heavily in AI research, including building the world’s most powerful AI-specific supercomputer. Its main aims are to develop better speech-recognition tools, automatically translate between different languages and help build a 3D virtual metaverse, but…

Longevity research often focuses on short-lived lab animals like mice – but a study of long-lived rockfish might offer new genetic clues for extending lifespans Rockfish are among the longest-living animals known to exist, and by studying the natural variation in their lifespans, researchers have discovered key insights into the genetic basis of longevity. Studies into ageing have traditionally focused on laboratory mice because they are easy to work with. However, Peter Sudmant at the University of California, Berkeley, and his colleagues adopted a different approach, studying longevity in creatures with longer lifespans. The researchers performed a genomic analysis of 88 species…
