If we’re not careful, Microsoft, Amazon, and other large companies will leverage their position to set the policy agenda for AI, as they have in many other sectors.
A recent study published in IEEE Transactions on Control of Network Systems discusses how artificial intelligence (AI) can be used to control microgrids in the event of a long-term power outage caused by natural disasters or human error. This study was conducted by a team of researchers at UC Santa Cruz and holds the potential to improve power restoration techniques, which are traditionally controlled by local utility companies. One benefit of microgrids is they can function to power a small area, such as a town, until the primary utility source comes back online.
“Nowadays, microgrids are really the thing that both people in industry and in academia are focusing on for the future power distribution systems,” said Dr. Yu Zhang, who is an assistant professor of electrical and computer engineering at UC Santa Cruz and co-author on the study.
For the study, the researchers used an AI-based approach to develop a novel method where microgrids could draw power from renewable energy sources while being disconnected from the primary utility source, known as “islanding mode”, but can also function while being connected to the source, as well. This new method, which they refer to as constrained policy optimization (CPO), uses a machine learning algorithm that learns from outside input, such as real-time changes in environmental or power conditions, and makes the best-informed decisions on what to do next.
RIO DE JANEIRO (AP) — City lawmakers in Brazil have enacted what appears to be the nation’s first legislation written entirely by artificial intelligence — even if they didn’t know it at the time.
The experimental ordinance was passed in October in the southern city of Porto Alegre and city councilman Ramiro Rosário revealed this week that it was written by a chatbot, sparking objections and raising questions about the role of artificial intelligence in public policy.
Rosário told The Associated Press that he asked OpenAI’s chatbot ChatGPT to craft a proposal to prevent the city from charging taxpayers to replace water consumption meters if they are stolen. He then presented it to his 35 peers on the council without making a single change or even letting them know about its unprecedented origin.
Just weeks before the management shakeup at OpenAI rocked Silicon Valley and made international news, the company’s cofounder and chief scientist Ilya Sutskever explored the transformative potential of artificial general intelligence (AGI), highlighting how it could surpass human intelligence and profoundly transform every aspect of life. Hear his take on the promises and perils of AGI — and his optimistic case for how unprecedented collaboration will ensure its safe and beneficial development. (Recorded October 17, 2023)

I suggest two responses to this difficult challenge for the United States and its allies: At the time of attack, the allies should respond with nonnuclear retaliation as long as politically feasible, in order to prevent further nuclear escalation. However, this will be difficult given the likely post-strike panic and hysteria. So, in preparation, the US should deconcentrate its northeast Asian conventional footprint, to reduce North Korean opportunities to engage in nuclear blackmail regarding regional American clusters of military equipment and personnel, and to reduce potential US casualties and consequent massive retaliation pressures if North Korea does launch a nuclear attack.
North Korean first-use incentives. The incentives for North Korea to use nuclear weapons first in a major conflict are powerful:
Operationally, North Korea will likely have only a very short time window to use its weapons of mass destruction. The Americans will almost certainly try to immediately suppress Northern missiles. An imminent, massive US-South Korea disarming strike creates an extreme use-it-or-lose-it dilemma for Pyongyang. If Kim Jong-Un does not use his nuclear weapons at the start of hostilities, most will be destroyed a short time later by allied airpower, turning an inter-Korean conflict into a conventional war that the North will probably lose. Frighteningly, this may encourage Kim to also release his strategic nuclear weapons almost immediately after fighting begins.
Large Language Models (LLMs) have shown great capabilities in various natural language tasks such as text summarization, question answering, generating code, etc., emerging as a powerful solution to many real-world problems. One area where these models struggle, though, is goal-directed conversations where they have to accomplish a goal through conversing, for example, acting as an effective travel agent to provide tailored travel plans. In practice, they generally provide verbose and non-personalized responses.
Models trained with supervised fine-tuning or single-step reinforcement learning (RL) commonly struggle with such tasks as they are not optimized for overall conversational outcomes after multiple interactions. Moreover, another area where they lack is dealing with uncertainty in such conversations. In this paper, the researchers from UC Berkeley have explored a new method to adapt LLMs with RL for goal-directed dialogues. Their contributions include an optimized zero-shot algorithm and a novel system called imagination engine (IE) that generates task-relevant and diverse questions to train downstream agents.
Since the IE cannot produce effective agents by itself, the researchers utilize an LLM to generate possible scenarios. To enhance the effectiveness of an agent in achieving desired outcomes, multi-step reinforcement learning is necessary to determine the optimal strategy. The researchers have made one modification to this approach. Instead of using any on-policy samples, they used offline value-based RL to learn a policy from the synthetic data itself.
In an article published yesterday in MIT Technology Review, Rachel Nuwer wrote a thought provoking piece exploring the boundaries between life and death.
Beyond the brain and brain death itself, related efforts are studying and attempting to develop techniques for restoring metabolic function in a number of organs other than the brain after death, including the heart and kidneys, which could greatly enhance organ donation capabilities.
While these developments are promising, researchers caution against overpromising. The path to these medical advancements is paved with years of research and ethical considerations. The exploration into the dying process will surely challenge not only scientific and medical fields but also societal, theological, and legal considerations, as it reshapes our understanding of one of life’s most profound phenomena. At some point, policy and regulations will need to follow—further adding to the complexity of the topic.

Two recent studies due to be presented as posters at the American Heart Association (AHA) Scientific Sessions 2023 between November 11–13 examine how frequent cannabis use could potentially lead to increased chances of cardiology issues, including heart attack, stroke, or heart failure. These studies were conducted by an international team of researchers and holds the potential to help scientists, medical professionals, and the public better understand the long-term health risks associated with cannabis use, specifically pertaining to cardiovascular concerns.
For the first study, which was conducted by the All of Us Research Program, researchers enlisted 156,999 participants who had not experienced heart failure at the time of the study’s enrollment to take part in a survey-based study to evaluate their cannabis use habits and conduct a follow-up survey 45 months later. The results indicated that heart failure emerged with 2,958 (1.88 percent) of the participants during the 48-month study period along with a 34 percent increased risk of emerging heart failure for participants were reported daily cannabis use compared to participants who didn’t use cannabis.
“Our results should encourage more researchers to study the use of marijuana to better understand its health implications, especially on cardiovascular risk,” said Dr. Yakubu Bene-Alhasan, who is a resident physician at Medstar Health and lead author of the study. “We want to provide the population with high-quality information on marijuana use and to help inform policy decisions at the state level, to educate patients and to guide health care professionals.”
Although essentially the United Nations are now making nuclear weapons illegal with new treaties like nuclear disarmament. Russia currently has taken another route for globalization and possibly nuclear escalation. As currently the doomsday clock seems closer to midnight which could mean the end of the world scenarios due to Russias escalation and the possibility of all out nuclear war globally and then nuclear annihilation of the planet. Even with current wars are actually seemingly always going on but this global escalation of nuclear war is a zero sum game as no one would be the winner due to radiation levels circulating the planet. I do think that the us and china are in a treaty but so far Russia is still escalating which now holds the world now ransom.
This is a summary of Policy Brief 139 which is available with full references on the Toda Peace Institute’s website.
In January 2021, a global treaty came into force outlawing the bomb. The Treaty on the Prohibition of Nuclear Weapons (TPNW or Ban Treaty) is the most significant multilateral development in nuclear arms control since the Non-Proliferation Treaty’s (NPT) entry into force in 1970. It establishes a new normative settling point on the ethics, legality and legitimacy of the bomb.
