These Newly Discovered Cells Breathe in Two Ways

The team members went through a process of incrementally determining what elements and molecules the bacterial strain could grow on. They already knew it could use oxygen, so they tested other combinations in the lab. When oxygen was absent, RSW1 could process hydrogen gas and elemental sulfur—chemicals it would find spewing from a volcanic vent—and create hydrogen sulfide as a product. Yet while the cells were technically alive in this state, they didn’t grow or replicate. They were making a small amount of energy—just enough to stay alive, nothing more. “The cell was just sitting there spinning its wheels without getting any real metabolic or biomass gain out of it,” Boyd said.
Then the team added oxygen back into the mix. As expected, the bacteria grew faster. But, to the researchers’ surprise, RSW1 also still produced hydrogen sulfide gas, as if it were anaerobically respiring. In fact, the bacteria seemed to be breathing both aerobically and anaerobically at once, and benefiting from the energy of both processes. This double respiration went further than the earlier reports: The cell wasn’t just producing sulfide in the presence of oxygen but was also performing both conflicting processes at the same time. Bacteria simply shouldn’t be able to do that.
“That set us down this path of ‘OK, what the heck’s really going on here?’” Boyd said.
Breathing Two Ways
RSW1 appears to have a hybrid metabolism, running an anaerobic sulfur-based mode at the same time it runs an aerobic one using oxygen.
“For an organism to be able to bridge both those metabolisms is very unique,” said Ranjani Murali, an environmental microbiologist at the University of Nevada, Las Vegas, who was not involved in the research. Normally when anaerobic organisms are exposed to oxygen, damaging molecules known as reactive oxygen compounds create stress, she said. “For that not to happen is really interesting.”

Boyd’s team observed that the bacteria grew best when running both metabolisms simultaneously. It may be an advantage in its unique environment: Oxygen isn’t evenly distributed in hot springs like those where RSW1 lives. In constantly changing conditions, where you could be bathed in oxygen one moment only for it to disappear, hedging one’s metabolic bets might be a highly adaptive trait.
Other microbes have been observed breathing two ways at once: anaerobically with nitrate and aerobically with oxygen. But those processes use entirely different chemical pathways, and when paired together, they tend to present an energetic cost to the microbes. In contrast, RSW1’s hybrid sulfur/oxygen metabolism bolsters the cells instead of dragging them down.
This kind of dual respiration may have evaded detection until now because it was considered impossible. “You have really no reason to look” for something like this, Boyd said. Additionally, oxygen and sulfide react with each other quickly; unless you were watching for sulfide as a byproduct, you might miss it entirely, he added.
It’s possible, in fact, that microbes with dual metabolisms are widespread, Murali said. She pointed to the many habitats and organisms that exist at tenuous gradients between oxygen-rich and oxygen-free areas. One example is in submerged sediments, which can harbor cable bacteria. These elongated microbes orient themselves in such a way that one end of their bodies can use aerobic respiration in oxygenated water while the other end is buried deep in anoxic sediment and uses anaerobic respiration. Cable bacteria thrive in their precarious partition by physically separating their aerobic and anaerobic processes. But RSW1 appears to multitask while tumbling around in the roiling spring.
It’s still unknown how RSW1 bacteria manage to protect their anaerobic machinery from oxygen. Murali speculated that the cells might create chemical supercomplexes within themselves that can surround, isolate and “scavenge” oxygen, she said—using it up quickly once they encounter it so there is no chance for the gas to interfere with the sulfur-based breathing.
RSW1 and any other microbes that have dual metabolism make intriguing models for how microbial life may have evolved during the Great Oxygenation Event, Boyd said. “That must have been a quite chaotic time for microbes on the planet,” he said. As a slow drip of oxygen filtered into the atmosphere and sea, any life-form that could handle an occasional brush with the new, poisonous gas—or even use it to its energetic benefit—may have been at an advantage. In that time of transition, two metabolisms may have been better than one.

The AI Industry’s Scaling Obsession Is Headed for a Cliff

A new study from MIT suggests the biggest and most computationally intensive AI models may soon offer diminishing returns compared to smaller models. By mapping scaling laws against continued improvements in model efficiency, the researchers found that it could become harder to wring leaps in performance from giant models whereas efficiency gains could make models running on more modest hardware increasingly capable over the next decade.
“In the next five to 10 years, things are very likely to start narrowing,” says Neil Thompson, a computer scientist and professor at MIT involved in the study.
Leaps in efficiency, like those seen with DeepSeek’s remarkably low-cost model in January, have already served as a reality check for the AI industry, which is accustomed to burning massive amounts of compute.
As things stand, a frontier model from a company like OpenAI is currently much better than a model trained with a fraction of the compute from an academic lab. While the MIT team’s prediction might not hold if, for example, new training methods like reinforcement learning produce surprising new results, they suggest that big AI firms will have less of an edge in the future.
Hans Gundlach, a research scientist at MIT who led the analysis, became interested in the issue due to the unwieldy nature of running cutting edge models. Together with Thompson and Jayson Lynch, another research scientist at MIT, he mapped out the future performance of frontier models compared to those built with more modest computational means. Gundlach says the predicted trend is especially pronounced for the reasoning models that are now in vogue, which rely more on extra computation during inference.
Thompson says the results show the value of honing an algorithm as well as scaling up compute. “If you are spending a lot of money training these models, then you should absolutely be spending some of it trying to develop more efficient algorithms, because that can matter hugely,” he adds.
The study is particularly interesting given today’s AI infrastructure boom (or should we say “bubble”?)—which shows little sign of slowing down.
OpenAI and other US tech firms have signed hundred-billion-dollar deals to build AI infrastructure in the United States. “The world needs much more compute,” OpenAI’s president, Greg Brockman, proclaimed this week as he announced a partnership between OpenAI and Broadcom for custom AI chips.
A growing number of experts are questioning the soundness of these deals. Roughly 60 percent of the cost of building a data center goes toward GPUs, which tend to depreciate quickly. Partnerships between the major players also appear circular and opaque.

AI World: Oracle brings agents to bear on world of finance | Computer Weekly

At Oracle AI World in Las Vegas, the software giant has been showcasing new agentic artificial intelligence (AI) features within its Fusion Cloud Applications Enterprise Resource Planning (ERP) suite, and other parts of the Fusion Cloud product line-up.
Built in Oracle AI Agent Studio for Fusion, the agents will embed within finance processes to realise productivity gains, enhance business performance, and help accounts teams stay compliant with the various regulatory regimes they must adhere to.
Speaking to Computer Weekly in advance of the supplier’s announcements this week Oracle Applications vice president Hari Sankar said that business financial functions can benefit hugely from AI.
“Firstly, accounting is governed by rules, the focus is compliance, the focus is ensuring things are done right [and] that’s a big part of the role of finance,” said Sankar. “I want to make sure that I sign on the dotted line saying these numbers are accurate that I’m complying with rules and regulations.
“That will never change but if you look at how it is performed today it’s a very labour intensive process so we believe there’s a lot of opportunity for automation.”
Sankar continued: “Secondly, a lot of accounting work tends to be back-end loaded at the end of the month or quarter. There are a lot of adjustments, reconciliations, all that needs to be done [and] these adjustments and reconciliations need to be documented because they need to be auditable.
“What AI agents give you is an opportunity to take those processes from a back-end fire drill to a set of continuous processes that happen throughout each quarter.”
Rondy Ng, Oracle executive vice president of applications development, added: “Oracle is ushering in a new era of agent-driven finance, where AI assistants turn fragmented, complex, staff-heavy processes into proactive, continuous operations that free teams to focus on judgment and strategic outcomes.
“Finance leaders gain a step change in operational efficiency and real-time business insights to help drive faster decisions and close cycles, stronger compliance and auditability, and healthier working capital.”
The new agents are prebuilt and integrate natively with both Fusion Cloud ERP and Fusion Cloud Enterprise Performance Management (EPM) at no extra cost to the customer.
The new agents include Payables Agent to help manage inbound invoices, Ledger Agent to help improve overall financial management and improve visibility, Planning Agent to help finance teams improve their planning processes, and Payments Agent to help optimise outbound payments.
Customer insight: Choctaw Indian nation uses Fusion AI
Although it is yet to venture down the agentic path, one of the US’ largest Indian nations, the 250,000-strong Choctaw Nation of Oklahoma, are incorporating Oracle Fusion Cloud Applications into its workflows, is already using various embedded Fusion AI features to automate various processes and goals.
With roots dating back centuries the Oklahoma Choctaw operate as a sovereign nation and as such the tribal administrators run a range of programmes in areas such as education, healthcare, housing. The nation even has an independent judiciary dating back to the 1830s.
The tribe also oversees a range of business activities, operating casinos, resorts and restaurants, and agriculture and farming.
The Choctaw government turned to Oracle’s AI services out of a desire to streamline its business processes, expand its capabilities and offer an evolving range of services to its members. At the same time, it is also spinning up Oracle Cloud Infrastructure (OCI) Generative AI to support translation between English and Choctaw, and preserve and grow its pre-Colombian language, which has fewer than 300 living speakers.
“For sovereign nations, leadership means planning for future generations. Embracing AI is key to building a strong foundation that supports our values, drives economic growth, and secures our long-term success,” said Emily Crow, Choctaw Nation IT director of enterprise services.
“With Oracle Fusion Applications, we’ve been able to automate key business processes, improve insights, and help grow the next generation of leaders. We’ve already adopted over 40 generative AI capabilities and look forward to leveraging more of Oracle’s AI agents and the AI Agent Studio to better support our people and improve operational efficiency as we continue to expand,” she said.
“With broad and complex operations, it’s often challenging for tribal nations to oversee business and workforce data across multiple industries while also meeting unique regulatory requirements,” said Steve Miranda, executive vice president of applications development at Oracle.
“With Oracle Fusion Applications, the Choctaw Nation has been able to take advantage of advanced AI capabilities to increase productivity, streamline critical business processes, cultivate the next generation of leaders, and set the stage for a future of innovation and growth.”
The Choctaw IT team is using Oracle Fusion Cloud AI features in two core areas, finance and human resources.
On the HR side, seeking to improve the experience for its 13,000-plus employees, generate more insightful data on its workforce, and reduce time-consuming manual processes, it is now using AI-powered features in Fusion Cloud Human Capital Management (HCM).
These features include agentic capabilities to support employees in areas such as goal-setting and performance reviews, and career and skills development guidance and opportunity discovery.
The organisation is already realising benefits in several areas – beyond mere time-savings it said it was now able to scale career growth conversations more broadly across its employee base.
Turning to financial matters, the Choctaw Nation is using Fusion Cloud ERP in the service of increasing productivity, reducing costs and improving financial controls.
Although it has not yet tried out the new agents, it is already using embedded AI capabilities to streamline its invoice processing, but it also hopes to implement more AI-powered features such as predictive cash forecasting and narrative reporting.
