For the first time, US scientists have achieved a fusion reaction with net energy gain. But the dream of limitless zero-carbon energy is still a long way from reality.

The FT’s Simon Mundy meets scientists and investors in the UK, France and US, to see how close we really are to commercial fusion power.
PBS NewsHour – Artificial intelligence, robotics and gene sequencing are the stuff of headlines, science fiction and sometimes even our worst fears. It’s all on view at the new MIT Museum. A place where the latest scientific advancements fill galleries, but only really work with your input. Special correspondent Jared Bowen of GBH Boston looks at this artistic frontier for our arts and culture series, “CANVAS.”
From AI in the home to robots in the workplace, the presence of AI all around us compels us to question its potential and recognize the risks. What has become clear is that the more we advance AI technology and consider machine ability versus human ability, the more we need to mind the gap.
NASA Goddard (December 2022) – NASA is developing the Earth System Observatory, the core of which is five satellite missions providing critical data on climate change, severe weather and other natural hazards, wildfires, and global food production.
These observations will address the most pressing questions about our changing planet. Taken together as a single Observatory, NASA will have a holistic, 3D view of Earth to better understand how our planet’s complex systems work together and improve our capability to predict how our climate may change.
NASA’s Open Source Science strategy is the key to bringing the data from these missions together into a single observatory to help understand the earth as a system and accelerate our ability to use this understanding. These observations will better inform decision-makers on how our planet is changing, with greater precision on previously unimaginable scales – from entire continents down to individual trees, from atmosphere to bedrock.
The covid-19 pandemic has reinforced humanity’s dependence on modern tech, but the same tools that enable remote working are also being used to spread disinformation and perpetuate cybercrime. Ambivalence towards technology is nothing new. Read more of our coverage of Science & technology: https://econ.st/3CdkVa5
How has Einstein’s work on photons ushered in a golden age of light? Oliver Morton, The Economist’s briefings editor, explores why laser’s applications have been spectacular and how solar power became the cheapest source of electricity in many countries.
A method for printing 3D objects that can control living organisms in predicable ways has been developed by an interdisciplinary team of researchers at MIT and elsewhere. This technique may lead to 3D printing of biomedical tools that can be customized to fit the physical body and biomarkers of its users.
