A Foreign Policy for a Changed World
Nothing in world politics is inevitable. The underlying elements of national power, such as demography, geography, and natural resources, matter, but history shows that these are not enough to determine which countries will shape the future. It is the strategic decisions countries make that matter most—how they organize themselves internally, what they invest in, whom they choose to align with and who wants to align with them, which wars they fight, which they deter, and which they avoid.
Can a Divided America Deter China and Russia?
The United States now confronts graver threats to its security than it has in decades, perhaps ever. Never before has it faced four allied antagonists at the same time—Russia, China, North Korea, and Iran—whose collective nuclear arsenal could within a few years be nearly double the size of its own. Not since the Korean War has the United States had to contend with powerful military rivals in both Europe and Asia. And no one alive can remember a time when an adversary had as much economic, scientific, technological, and military power as China does today.

Plastic is cheap to make and shockingly profitable. It’s everywhere. And we’re all paying the price.
Plastic, and the profusion of waste it creates, can hide in plain sight, a ubiquitous part of our lives we rarely question. But a closer examination of the situation can be shocking.
Indeed, the scale of the problem is hard to internalize. To date, humans have created around 11 billion metric tons of plastic. This amount surpasses the biomass of all animals, both terrestrial and marine, according to a 2020 study published in Nature.
Currently, about 430 million tons of plastic is produced yearly, according to the United Nations Environment Programme (UNEP)—significantly more than the weight of all human beings combined. One-third of this total takes the form of single-use plastics, which humans interact with for seconds or minutes before discarding.
Philosophers, cognitive scientists, and engineers are grappling with what it would take for AI to become conscious.
David Chalmers was not expecting the invitation he received in September of last year. As a leading authority on consciousness, Chalmers regularly circles the world delivering talks at universities and academic meetings to rapt audiences of philosophers—the sort of people who might spend hours debating whether the world outside their own heads is real and then go blithely about the rest of their day. This latest request, though, came from a surprising source: the organizers of the Conference on Neural Information Processing Systems (NeurIPS), a yearly gathering of the brightest minds in artificial intelligence.
0:15 AI can predict your risk of Parkinson’s – RETFound was trained using 1.6 million retinal images which gave it a picture of a healthy retina. Then its creators added images of eyes from people with certain conditions. Our eyes are a window to our health. They’re the only place where doctors can directly observe capillaries, our smallest blood vessels, enabling detection of cardiovascular illnesses such as hypertension. Eyes are also linked to the central nervous system, giving an insight into neural tissue, too. The RETFound tool was best at picking up eye diseases such as diabetic retinopathy. On Parkinson’s, stroke and heart disease, it performed not quite as well but still beat other AI models.
2:08 These are the most detailed heat maps of our planet – They use imagery from a satellite called HotSat-1 which can detect heat and cold at a resolution of 3.5 metres. The satellite can precisely map the fronts of forest fires, detect and monitor heat islands in cities and measure the thermal efficiency of buildings. This information can drive more effective decision-making.
3:51 AI designed this robot in 26 seconds – Researchers from Northwestern University gave an AI a simple prompt. ‘Design a robot that can walk across a flat surface’. By the 9th iteration, the AI had successfully met its brief. The robot could walk half its own body length per second. The entire iteration process took just 26 seconds and it ran on a laptop.
6:26 Norway completed it’s largest rewilding project – It’s centred around Sveagruva, a 100-year-old mining town on the Arctic island of Svalbard. Norway decided to close the town and its mining operations in 2017 and return the area to its natural state, restoring biodiversity and the local ecosystem.

Past the halfway point, Extremely Large Telescope prepares to receive first mirrors
A web of steel girders is rising from the flattened summit of Cerro Armazones, 3000 meters above sea level in Chile’s Atacama Desert. The dome it will support will be vast—with a footprint as big as a soccer field and almost as tall as the Statue of Liberty— and unexpectedly nimble: It will smoothly rotate on rails as a giant telescope inside tracks stars through the night.

Increasingly, companies are reselling their own products. Should you get into the game?
Summary: The average U.S. household contains a trove of potentially reusable goods worth roughly $4,500. That’s a lot of trapped value, and companies are at last getting serious about accessing it—by developing new resale capabilities. Resale has been with us for a very long time, of course—at yard sales, on used-car lots, in classified ads.
An advanced AI model considers much more than what competitors are charging.
Summary: In today’s fast-paced world of digital retailing, the ability to revise prices swiftly and on a large scale has emerged as a decisive differentiator for companies. Many retailers now track competitors’ prices via systems that scrape rivals’ websites and use this information as an input to set their own prices manually or automatically. A common strategy is to charge X dollars or X percent less than a target competitor. However, retailers that use such simple heuristics miss significant opportunities to fine-tune pricing.
0:15 Why engagement in the news is in decline – A massive media survey looked at trust and engagement in the news and found both are in steady decline. Just 48% of people say they are very or extremely interested in the news in 2023 down from 63% in 2017. Trust in the news has fallen 2 percentage points in a year. Now, only 40% say they trust the news most of the time and 36% say they actively avoid the news sometimes or often.
1:53 This robot can help people with disabilities dress – The robot was designed by a team at Carnegie Mellon University (CMU). They used a simulation to teach it how to perform its task. The team used an AI-driven approach called ‘reinforcement learning’. The robot was rewarded each time it correctly placed a shirt further along an arm.
3:25 Company captures and stores CO2 with limestone – Heirloom takes crushed limestone and heats it in a kiln powered by renewable energy. The reaction generates two products. These are CO2, which can be permanently stored underground or in materials like concrete and a powder, which is hydrated with water to make calcium hydroxide. When the calcium hydroxide is spread onto trays, it absorbs CO2 from the air to become limestone and the whole process can begin again.
