The first time she tried to seduce me,
(atoms falling in a vacuum)
she asked about blackberries—
(every mass exerts some gravity)
Did I know their season, where they grow?
(galvanometers, gravimeters)
I could answer both easily—
(tools to measure small attractions)
down the dirt road in September.
(devices that report, don’t interfere)
She eagerly went there with me,
(variations in readings occur)
We ate more berries than we kept.
(electron exchange may explain this)
The sweet dark juice painted our lips.

Data centers for AI are turning the world of power generation on its head. There isn’t enough power capacity on the grid to even come close to how much energy is needed for the number being built. And traditional transmission and distribution networks aren’t efficient enough to take full advantage of all the power available. According to the U.S. Energy Information Administration (EIA), annual transmission and distribution losses average about 5 percent. The rate is much higher in some other parts of the world. Hence, hyperscalers such as Amazon Web Services, Google Cloud and Microsoft Azure are investigating every avenue to gain more power and raise efficiency.
Microsoft, for example, is extolling the potential virtues of high-temperature superconductors (HTS) as a replacement for copper wiring. According to the company, HTS can improve energy efficiency by reducing transmission losses, increasing the resiliency of electrical grids, and limiting the impact of data centers on communities by reducing the amount of space required to move power.
“Because superconductors take up less space to move large amounts of power, they could help us build cleaner, more compact systems,” Alastair Speirs, the general manager of global infrastructure at Microsoft wrote in a blog post.
Copper is a good conductor, but current encounters resistance as it moves along the line. This generates heat, lowers efficiency, and restricts how much current can be moved. HTS largely eliminates this resistance factor, as it’s made of superconducting materials that are cooled to cryogenic temperatures. (Despite the name, high-temperature superconductors still rely on frigid temperatures—albeit significantly warmer than those required by traditional superconductors.)
The resulting cables are smaller and lighter than copper wiring, don’t lower voltage as they transmit current, and don’t produce heat. This fits nicely into the needs of AI data centers that are trying to cram massive electrical loads into a tiny footprint. Fewer substations would also be needed. According to Speirs, next-gen superconducting transmission lines deliver capacity that is an order of magnitude higher than conventional lines at the same voltage level.
Microsoft is working with partners on the advancement of this technology including an investment of US $75 million into Veir, a superconducting power technology developer. Veir’s conductors use HTS tape, most commonly based on a class of materials known as rare-earth barium copper oxide (REBCO). REBCO is a ceramic superconducting layer deposited as a thin film on a metal substrate, then engineered into a rugged conductor that can be assembled into power cables.
“The key distinction from copper or aluminum is that, at operating temperature, the superconducting layer carries current with almost no electrical resistance, enabling very high current density in a much more compact form factor,” says Tim Heidel, Veir’s CEO and co-founder.
Ruslan Nagimov, the principal infrastructure engineer for Cloud Operations and Innovation at Microsoft, stands near the world’s first HTS-powered rack prototype.Microsoft
HTS cables still operate at cryogenic temperatures, so cooling must be integrated into the power delivery system design. Veir maintains a low operating temperature using a closed-loop liquid nitrogen system: The nitrogen circulates through the length of the cable, exits at the far end, is re-cooled, and then recirculated back to the start.
“Liquid nitrogen is a plentiful, low cost, safe material used in numerous critical commercial and industrial applications at enormous scale,” says Heidel. “We are leveraging the experience and standards for working with liquid nitrogen proven in other industries to design stable, data center solutions designed for continuous operation, with monitoring and controls that fit critical infrastructure expectations rather than lab conditions.”
HTS cable cooling can either be done within the data center or externally. Heidel favors the latter as that minimizes footprint and operational complexity indoors. Liquid nitrogen lines are fed into the facility to serve the superconductors. They deliver power to where it’s needed and the cooling system is managed like other facility subsystem.
Rare earth materials, cooling loops, cryogenic temperatures—all of this adds considerably to costs. Thus, HTS isn’t going to replace copper in the vast majority of applications. Heidel says the economics are most compelling where power delivery is constrained by space, weight, voltage drop, and heat.
“In those cases, the value shows up at the system level: smaller footprints, reduced resistive losses, and more flexibility in how you route power,” says Heidel. “As the technology scales, costs should improve through higher-volume HTS tape manufacturing and better yields, and also through standardization of the surrounding system hardware, installation practices, and operating playbooks that reduce design complexity and deployment risk.”
AI data centers are becoming the perfect proving ground for this approach. Hyperscalers are willing to spend to develop higher-efficiency systems. They can balance spending on development against the revenue they might make by delivering AI services broadly.
“HTS manufacturing has matured—particularly on the tape side—which improves cost and supply availability,” says Husam Alissa, Microsoft’s director of systems technology. “Our focus currently is on validating and derisking this technology with our partners with focus on systems design and integration.”

IEEE has enhanced its standing as a trusted, neutral authority on the role of technology in climate change mitigation and adaption. Last year it became the first technical association to be invited to a U.N. Conference of the Parties on Climate Change.
IEEE representatives participated in several sessions at COP30, held from 11 to 20 November in Belém, Brazil. More than 56,000 delegates attended, including policymakers, technologists, and representatives from industry, finance, and development agencies.
Following the conference, IEEE helped host the selective International Symposium on Achieving a Sustainable Climate. The International Telecommunication Union and IEEE hosted ISASC on 16 and 17 December at ITU’s headquarters in Geneva. Among the more than 100 people who attended were U.N. agency representatives, diplomats, senior leaders from academia, and experts from government, industry, nongovernment organizations, and standards development bodies.
Power and energy expert Saifur Rahman, the 2023 IEEE president, led IEEE’s delegation at both events. Rahman is the immediate past chair of IEEE’s Technology for a Sustainable Climate Matrix Organization, which coordinates, communicates, and amplifies the organization’s efforts.
IEEE first attended a COP in 2021.
“Over successive COPs, IEEE’s role has evolved from contributing individual technical sessions to being recognized as a trusted partner in climate action,” Rahman noted in a summary of COP30. “There is [a] growing demand for engineering insight, not just to discuss technologies but [also] to help design pathways for deployment, capacity-building, and long-term resilience.”
Joining Rahman at COP30 were IEEE Fellow Claudio Canizares and IEEE Member Filipe Emídio Tôrres.
Canizares is a professor of electrical and computer engineering at the University of Waterloo, in Ontario, Canada, and the executive director of the university’s sustainable energy institute.
Tôrres chairs the IEEE Centro-Norte Brasil Section (Brazil Chapter). An entrepreneur and a former professor, he is pursuing a Ph.D. in biomedical engineering at the University of Brasilia. He also represented the IEEE Young Professionals group while attending the conference.
In the Engineering for Climate Resilience: Water Planning, Energy Transition, Biodiversity session, Rahman showed a video from his 2024 visit to Shennongjia, China, where he monitored a clean energy project designed to protect endangered snub-nosed monkeys from human encroachment. The project integrates renewable energy, which helps preserve the forest and its wildlife.
Rahman also chaired a session at the Sustainable Development Goal Pavilion on balancing decarbonization efforts between industrialized and emerging economies.
Additionally, he participated in a joint panel discussion hosted by IEEE and the World Federation of Engineering Organizations on engineering strategies for climate resilience, including energy transition and biodiversity.
Rahman, Canizares, and Tôrres took part in a session on clean-tech solutions for a sustainable climate, hosted by the International Youth Nuclear Congress. The topics included fossil fuel–free electricity for communications in remote areas and affordable electricity solutions for off-grid areas.
The three also joined several panels organized by the IYNC that addressed climate resilience, career pathways in sustainability, and a mentoring program.
“Over successive COPs, IEEE’s role has evolved from contributing individual technical sessions to being recognized as a trusted partner in climate action.” —Saifur Rahman, 2023 IEEE president
The IYNC hosted the Voices of Transition: Including Pathways to a Clean Energy Future session, for which Tôrres and Rahman were panelists. They discussed the need to include underrepresented and marginalized groups, which often get overlooked in projects that convert communities to renewable energy.
Rahman, Canizares, and Tôrres visited the COP Village, where they met several of the 5,000 Indigenous leaders participating in the conference and discussed potential partnerships and collaborations. Climate change has made the land where the Indigenous people live more susceptible to severe droughts and wildfires, particularly in the Amazon region.
Rahman and Tôrres took a field trip to the Federal University of Para, where they met several faculty members and students and toured the LASSE engineering lab.
Tôrres, who says representing IEEE at COP30 was transformative, wrote a detailed report about the event.
“The experience reaffirmed my belief that engineering and technology, when combined with respect for cultural diversity, can play a critical role in shaping a more sustainable and equitable world,” he wrote. “It highlighted the importance of combining cutting-edge technological solutions with Indigenous wisdom and cultural knowledge to address the climate crisis.”
Rahman and Canizares give an overview of their COP30 experiences in an IEEE webinar.
“IEEE has a place at the table,” Rahman says in the video. “We want to showcase outside our comfort zone what IEEE can do. We go to all these global events so that our name becomes a familiar term. We are the first technical association organization ever to go to COP and talk about engineering.”
Canizares added that IEEE is now collaborating closely with the United Nations.
“This is an important interaction. And I think, moving forward, IEEE will become more relevant, particularly in the context of technology deployment,” he said. “As governments start technology deployments, they will see IEEE as a provider of solutions.”
Rahman was the general chair of the ISASC event, which focused on the delivery and deployment of clean energy. Among the presenters were IEEE members including Canizares, Paulina Chan, Surekha Deshmukh, Ashutosh Dutta, Tariq Durrani, Samina Husain, Bruce Kraemer, Bruno Meyer, Carlo Alberto Nucci, and Seizo Onoe.
Sessions were organized around six themes: energy transition, information and communication technology, financing, case studies, technical standards, and public-private collaborations. A detailed report includes the discussions, insights, and opportunities identified throughout ISASC.
Here are some key takeaways.
As part of ISASC, IEEE presented a technology assessment tool prototype. The web-based platform is designed to help policymakers, practitioners, and investors compare technology options against climate goals.
The tool can run a comparative analysis of sustainable climate technologies and integrate publicly available, expert-validated data.
The ISASC report concluded that by connecting engineering expertise with real-world deployment challenges, IEEE is working to translate global climate goals into measurable actions.
The discussions highlighted that the path forward lies less in inventing new technologies and more in aligning systems to deliver ones that already exist.
Summaries of COP30 and ISASC are available on the IEEE Technology for a Sustainable Climate website.

So, humanoid robots are nearing peak human performance. I would point out, though, that this is likely very far from peak robot performance, which has yet to be effectively exploited, because it requires more than just copying humans.

NASA’s Perseverance rover can now precisely determine its own location on Mars without waiting for human help from Earth. This is possible thanks to a new technology called Mars Global Localization. This technology rapidly compares panoramic images from the rover’s navigation cameras with onboard orbital terrain maps. It’s done with an algorithm that runs on the rover’s Helicopter Base Station processor, which was originally used to communicate with the Ingenuity Mars Helicopter. In a few minutes, the algorithm can pinpoint Perseverance’s position to within about 10 inches (25 centimeters). The technology will help the rover drive farther autonomously and keep exploring.

This IROS 2025 keynote is from Tim Chung who is now at Microsoft, on “Catalyzing the Future of Human, Robot, and AI Agent Teams in the Physical World.”
The convergence of technologies—from foundation AI models to diverse sensors and actuators to ubiquitous connectivity—is transforming the nature of interactions in the physical and digital world. People have accelerated their collaborative connections and productivity through digital and immersive technologies, no longer limited by geography or language or access. Humans have also leveraged and interacted with AI in many different forms, with the advent of hyperscale AI models (i.e., large language models) forever changing (and at an ever-astonishing pace) the nature of human-AI teams, realized in this era of the AI “copilot.” Similarly, robotics and automation technologies now afford greater opportunities to work with and/or near humans, allowing for increasingly collaborative physical robots to dramatically impact real-world activities. It is the compounding effect of enabling all three capabilities, each complementary to one another in valuable ways, and we envision the triad formed by human-robot-AI teams as revolutionizing the future of society, the economy, and of technology.

This week’s CMU RI Seminar is from Jitendra Malik at UC Berkeley, on “Robot Learning, With Inspiration From Child Development.”
For intelligent robots to become ubiquitous, we need to “solve” locomotion, navigation and manipulation at sufficient reliability in widely varying environments. In locomotion, we now have demonstrations of humanoid walking in a variety of challenging environments. In navigation, we pursued the task of “Go to Any Thing” – a robot, on entering a newly rented Airbnb, should be able to find objects such as TV sets or potted plants. RL in simulation and sim-to-real have been workhorse technologies for us, assisted by a few technical innovations. I will sketch promising directions for future work.

More money has been invested in AI than it took to land on the moon. Spending on the technology this year is projected to reach up to $700 billion, almost double last year’s spending. Part of the impetus for this frantic outlay is a conviction among investors and policymakers in the United States that it needs to “beat China.” Indeed, headlines have long cast AI development as a zero-sum rivalry between the U.S. and China, framing the technology’s advance as an arms race with a defined finish line. The narrative implies speed, symmetry, and a common objective.
But a closer look at AI development in the two countries shows they’re not only not racing toward the same finish line: “The U.S. and China are running in very different lanes,” says Selina Xu, who leads China and AI policy research for Eric Schmidt, the tech investor, philanthropist and former Google chief, in New York City. “The U.S. is doubling down on scaling,” in pursuit of artificial general intelligence (AGI) Xu says, “while for China it’s more about boosting economic productivity and real-world impact.”
Lumping the U.S. and China onto a single AI scoreboard isn’t just inaccurate, it can impact policy and business decisions in a harmful way. “An arms race can become a self-fulfilling prophecy,” Xu says. “If companies and governments all embrace a ‘race to the bottom’ mentality, they will eschew necessary security and safety guardrails for the sake of being ahead. That increases the odds of AI-related crises.”
As machine learning advanced in the 2010s, prominent public figures such as Stephen Hawking and Elon Musk warned that it would be impossible to separate AI’s general-purpose potential from its military and economic implications, echoing Cold War–era frameworks for strategic competition. “An arms race is an easy way to think about this situation even if it’s not exactly right,” says Karson Elmgren, a China researcher at the Institute for AI Policy and Strategy, a think tank in San Francisco. Frontier labs, investors, and media benefit from simple, comparable progress metrics, like larger models, better benchmarks, and more computing power, so they favor and compound the arms race framing.
Artificial general intelligence is the implied “finish line” if AI is an arms race. But one of the many problems with an AGI finish line is that by its very nature, a machine superintelligence would be smarter than humans and therefore impossible to control. “If superintelligence were to emerge in a particular country, there’s no guarantee that that country’s interests are going to win,” says Graham Webster, a China researcher at Stanford University, in Palo Alto, California.
An AGI finish line also assumes the U.S. and China are both optimizing for this goal and putting the majority of their resources towards it. This isn’t the case, as the two countries have starkly different economic landscapes.
After decades of rapid growth, China is now facing a grimmer reality. “China has been suffering through an economic slowdown for a mixture of reasons, from real estate to credit to consumption and youth unemployment,” says Xu, adding that the country’s leaders have been “trying to figure out what is the next economic driver that can get China to sustain its growth.”
Enter AI. Rather than pouring resources into speculative frontier models, Beijing has a pressing incentive to use the technology as a more immediate productivity engine. “In China we define AI as an enabler to improve existing industry, like healthcare, energy, or agriculture,” says AI policy researcher Liang Zheng, of Tsinghua University in Beijing, China. “The first priority is to use it to benefit ordinary people.”
To that end, AI investment in China is focused on embedding the technology into manufacturing, logistics, energy, finance, and public services. “It’s a long-term structural change, and companies must invest more in machines, software, and digitalization,” Liang says. “Even very small and medium enterprises are exploring use of AI to improve their productivity.”
China’s AI Plus initiative encourages using AI to boost efficiency. “Having a frontier technology doesn’t really move China towards an innovation-led developed economy,” says Kristy Loke, a fellow at MATS Research who focuses on China’s AI innovation and governance strategies. Instead, she says, “It’s really important to make sure that [these tools] are able to meet the demands of the Chinese economy, which are to industrialize faster, to do more smart manufacturing, to make sure they’re producing things in competitive processes.”
Automakers have embraced intelligent robots in “dark factories” with minimal human intervention; as of 2024, China had around five times more factory robots in use than the U.S. “We used to use human eyes for quality control and it was very inefficient,” says Liang. Now, computer vision systems detect errors and software predicts equipment failures, pausing production and scheduling just-in-time maintenance. Agricultural models advise farmers on crop selection, planting schedules, and pest control.
In healthcare, AI tools triage patients, interpret medical images, and assist diagnoses; Tsinghua is even piloting an AI “Agent Hospital” where physicians work alongside virtual clinical assistants. “In hospitals you used to have to wait a long time, but now you can use your agent to make a precise appointment,” Liang says. Many such applications use simpler “narrow AI” designed for specific tasks.
AI is also increasingly embedded across industries in the U.S., but the focus tends toward service-oriented and data-driven applications, leveraging large language models (LLMs) to handle unstructured data and automate communication. For example, banks use LLM-based assistants to help users manage accounts, find transactions, and handle routine requests; LLMs help healthcare professionals extract information from medical notes and clinical documentation.
“LLMs as a technology naturally fit the U.S. service-sector-based economy more so than the Chinese manufacturing economy,” Elmgren says.
The U.S. and China do compete more or less head-to-head in some AI-related areas, such as the underlying chips. The two have grappled to gain enough control over their supply chains to ensure national security, as recent tariff and export control fights have shown. “I think the main competitive element from a top level [for China] is to wriggle their way out of U.S. coercion over semiconductors. They want to have an independent capability to design, build, and package advanced semiconductors,” Webster says.
Military applications of AI are also a significant arena of U.S.–China competition, with both governments aiming to speed decision-making, improve intelligence, and increase autonomy in weapons systems. The U.S. Department of Defense launched its AI Acceleration Strategy last month, and China has explicitly integrated AI into its military modernization strategy under its policy of military-civil fusion. “From the perspective of specific military systems, there are incremental advantages that one side or the other can gain,” Webster says.
Despite China’s commitment to military and industrial applications, it has not yet picked an AI national champion. “After Deepseek in early 2025 the government could have easily said, ‘You guys are the winners, I’ll give you all the money, please build AGI,’ but they didn’t. They see being ‘close enough’ to the technological frontier as important, but putting all eggs in the AGI basket as a gamble,” Loke says.
American companies are also still working with Chinese technology and workers, despite a slow uncoupling of the two economies. Though it may seem counterintuitive, more cooperation—and less emphasis on cutthroat competition—could yield better results for all. “For building more secure, trustworthy AI, you need both U.S. and Chinese labs and policymakers to talk to each other, to reach consensus on what’s off limits, then compete within those boundaries,” Xu says. “The arms race narrative also just misses the actual on-the-ground reality of companies co-opting each other’s approaches, the amount of research that gets exchanged in academic communities, the supply chains and talent that permeates across borders, and just how intertwined the two ecosystems are.”

In the rapidly evolving world of engineering technology, professionals devote enormous energy to such tasks as mastering the latest frameworks, optimizing architectures, and refining machine learning models. It’s easy to let technical expertise become the sole measure of professional value. However, one of the most important skills an engineer can develop is the capacity to write and communicate effectively.
Whether you’re conducting research at a university or leading systems development projects at a global firm, your expertise can become impactful only when you share it in a way that others can understand and act upon. Without a clear narrative, even groundbreaking data or innovative designs can fail to gain traction, limiting their reach among colleagues and stakeholders, and in peer‑reviewed journals.
Writing is often labeled a “soft skill”—which can diminish its importance. In reality, communication is a core engineering competency. It lets us document methods, articulate research findings, and persuade decision-makers who determine whether projects move forward.
If your writing is dense, disorganized, or overloaded with technical jargon, the value of the underlying work can become obscured. A strong proposal might be dismissed not because the idea lacks merit but because the justification is difficult to follow.
Clear writing can strengthen the impact of your work. Poor writing can distract from the points you’re trying to make, as readers might not understand what you’re saying.
Technical writing differs from other forms of prose because readers expect information to follow predictable, logical patterns. Unclear writing can leave readers unsure of the author’s intent.
One of the most enduring frameworks for writing about technology in an understandable manner is the IMRaD structure: introduction, methods, results, and discussion.
More than just a template for academic papers, IMRaD is a road map for logical reasoning. Mastering the structure can help engineers communicate in a way that aligns with professional writing standards used in technical journals, so their work is better understood and more respected.
Despite technical communication’s importance, engineering curricula often limit or lack formal instruction in it.
Recognizing that gap, IEEE has expanded its role as a global knowledge leader by offering From Research to Publication: A Step-by-Step Guide to Technical Writing. The course is led by Traci Nathans-Kelly, director of the engineering communications program at Cornell.
Developed by IEEE Educational Activities and the IEEE Professional Communication Society, the learning opportunity goes beyond foundational writing skills. It addresses today’s challenges, such as the ethical use of generative AI in the writing workflow, the complexities of team-based authorship, and publishing strategies.
The program centers on core skill areas that can influence an engineer’s ability to communicate. Participants learn to master the IMRaD structure and learn advanced editing techniques to help strip away jargon, making complex ideas more accessible. In addition, the course covers strategic approaches to publishing work in high‑impact journals and improving a writer’s visibility within the technical community.
The course is available on the IEEE Learning Network. Participants earn professional development credit and a shareable digital badge. IEEE members receive a US $100 discount. Organizations can connect with an IEEE content specialist to offer the training to their teams.
