The world economy is defying gravity. That cannot last. Threats abound, including higher-for-longer interest rates
Even as wars rage and the geopolitical climate darkens, the world economy has been an irrepressible source of cheer. Only a year ago everyone agreed that high interest rates would soon bring about a recession. Now even the optimists have been confounded. America’s economy roared in the third quarter, growing at a stunning annualised pace of 4.9%. Around the world, inflation is falling, unemployment has mostly stayed low and the big central banks may have stopped their monetary tightening. China, stricken by a property crisis, looks likely to benefit from a modest stimulus. Unfortunately, however, this good cheer cannot last. The foundations for today’s growth look unstable. Peer ahead, and threats abound.

The Guardian Weekly (November 3, 2023) – The new issue features Bletchley Park, the main center of allied second world war codebreakers, and it’s no coincidence that the English country house was chosen as the venue for this week’s landmark summit on safety in artificial intelligence. The age of AI brings opportunities but also significant risks, as a number of experts in the field outlined in an open letter last week.
Global technology editor Dan Milmo discusses the pros and cons with one of the technology’s leading thinkers, Demis Hassabis, the CEO of Google DeepMind, who says the rise of AI must be thought of as seriously as the climate crisis. Then, Observer columnist Sonia Sodha argues that calling for AI to be reined in is not simply a sign of luddism.
As Israeli forces entered Gaza this week, Bethan McKernan and Rory Carroll report for us on the increasingly unbearable nature of life in the besieged enclave, and there’s expert analysis and commentary from Julian Borger, Peter Beaumont and Jason Burke.
If you pause for a second and think about the activities that occupy most of your day, presumably sleeping, eating, and engaging in social interactions are among the first that come to your mind. Perhaps surprisingly, a small area buried deep inside the brain, called the hypothalamus, is responsible for coordinating neuronal signals related to these activities. By controlling the homeostasis of the neuroendocrine, limbic, and autonomic nervous systems, the hypothalamus is a key brain region for many physiological and pathological processes. Despite its small size, the hypothalamus has a complex cellular organization and circuitry that determine its structural and functional organization. It is composed of 11 nuclei grouped by their location and has vast, mostly bidirectional connections with many neuronal and endocrine systems.
Plants bred or engineered to be short can stand up better to windstorms. They could also boost yields and benefit the environment
To an interstate traveler—or anyone lost in a corn maze—the most impressive feature of corn is its stature. Modern corn can grow twice as tall as a person, but height has drawbacks, making the plants vulnerable to wind and more difficult for farmers to tend. Plant scientists think corn can be improved by making it shorter, and leading seed companies are doing that through both conventional breeding and genetic engineering. Bayer has launched a short variety in Mexico, another company is selling its versions in the United States, and more are getting involved.

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.
