  • Use of AI could worsen racism and sexism in Australia, human rights commissioner warns | Artificial intelligence (AI)

    Use of AI could worsen racism and sexism in Australia, human rights commissioner warns | Artificial intelligence (AI)

    AI risks entrenching racism and sexism in Australia, the human rights commissioner has warned, amid internal Labor debate about how to respond to the emerging technology.

    Lorraine Finlay says the pursuit of productivity gains from AI should not come at the expense of discrimination if the technology is not properly regulated.

    Finlay’s comments follow Labor senator Michelle Ananda-Rajah breaking ranks to call for all Australian data to be “freed” to tech companies to prevent AI perpetuating overseas biases and reflect Australian life and culture.

    Ananda-Rajah is opposed to a dedicated AI act but believes content creators should be paid for their work.

    Sign up: AU Breaking News email

    Productivity gains from AI will be discussed next week at the federal government’s economic summit, as unions and industry bodies raise concerns about copyright and privacy protections.

    Media and arts groups have warned of “rampant theft” of intellectual property if big tech companies can take their content to train AI models.

    Finlay said a lack of transparency in what datasets AI tools are being trained on makes it difficult to identify which biases it may contain.

    “Algorithmic bias means that bias and unfairness is built into the tools that we’re using, and so the decisions that result will reflect that bias,” she said.

    “When you combine algorithmic bias with automation bias – which is where humans are more likely to rely on the decisions of machines and almost replace their own thinking – there’s a real risk that what we’re actually creating is discrimination and bias in a form where it’s so entrenched, we’re perhaps not even aware that it’s occurring.”

    The Human Rights Commission has consistently advocated for an AI act, bolstering existing legislation, including the Privacy Act, and rigorous testing for bias in AI tools. Finlay said the government should urgently establish new legislative guardrails.

    “Bias testing and auditing, ensuring proper human oversight review, you [do] need those variety of different measures in place,” she said.

    There is growing evidence that there is bias in AI tools in Australia and overseas, in areas such as medicine and job recruitment.

    An Australian study published in May found job candidates being interviewed by AI recruiters risked being discriminated against if they spoke with an accent or were living with a disability.

    Ananda-Rajah, who was a medical doctor and researcher in AI before entering parliament, said it was important for AI tools to be trained on Australian data, or risk perpetuating overseas biases.

    While the government has stressed the need for protecting intellectual property, she warned that not opening up domestic data would mean Australia would be “forever renting [AI] models from tech behemoths overseas” with no oversight or insight into their models or platforms.

    “AI must be trained on as much data as possible from as wide a population as possible or it will amplify biases, potentially harming the very people it is meant to serve,” Ananda-Rajah said.

    “We need to free our own data in order to train the models so that they better represent us.

    “I’m keen to monetise content creators while freeing the data. I think we can present an alternative to the pillage and plunder of overseas.”

    Ananda-Rajah raised skin cancer screening by AI as an example where the tools used for testing have been shown to have algorithmic bias. Ananda-Rajah said the way to overcome any bias or discrimination against certain patients would be to train “these models on as much diverse data from Australia as possible”, with appropriate protections for sensitive data.

    Finlay said any release of Australian data should be done in a fair way but she believes the focus should be on regulation.

    “Having diverse and representative data is absolutely a good thing … but it’s only one part of the solution,” she said.

    “We need to make sure that this technology is put in place in a way that’s fair to everybody and actually recognises the work and the contributions that humans are making.”

    An AI expert at La Trobe university and former data researcher at an AI company, Judith Bishop, said freeing up more Australian data could help train AI tools more appropriately – while warning AI tools developed overseas using international data may not reflect the needs of Australians – but that it was a small part of the solution.

    “We have to be careful that a system that was initially developed in other contexts is actually applicable for the [Australian] population, that we’re not relying on US models which have been trained on US data,” Bishop said.

    The eSafety commissioner, Julie Inman Grant, is also concerned by the lack of transparency around the data AI tools use.

    In a statement, she said tech companies should be transparent about their training data, develop reporting tools and must use diverse, accurate and representative data in their products.

    “The opacity of generative AI development and deployment is deeply problematic,” Inman Grant said. “This raises important questions about the extent to which LLMs [large language models] could amplify, even accelerate, harmful biases – including narrow or harmful gender norms and racial prejudices.

    “With the development of these systems concentrated in the hands of a few companies, there’s a real risk that certain bodies of evidence, voices and perspectives could be overshadowed or sidelined in generative outputs.”

  • BBVA and the University of Navarra embark on a ground-breaking applied research project into responsible AI

    BBVA and the University of Navarra embark on a ground-breaking applied research project into responsible AI

    With decision-making processes becoming increasingly automated, including loan approvals, recruitment or access to services, we must ensure that artificial intelligence systems are both fair and transparent. These challenges are not only technical but also social, and therefore require ethical reflection, oversight and institutional commitment. The Fair Learning project, coordinated by BBVA’s own Data University and the Institute of Data Science and Artificial Intelligence (DATAI) at the University of Navarra, aims to address this challenge from technological, philosophical and legal standpoints.

    Over the next three years, twenty experts—including BBVA data scientists and University of Navarra academics from various disciplines such as engineering, philosophy, medicine, law and economics—will work together to design a framework for detecting, mitigating and correcting AI bias, guaranteeing privacy, fairness and individual autonomy, and for defining best practices in line with current law and regulations.

    “This is a genuinely groundbreaking project in the financial sector and a further show of BBVA’s commitment to advancing its technological transformation without losing focus on people,” remarked Josep Amorós, project coordinator and Senior Manager of Analytics Transformation at BBVA, adding that “AI is already a central pillar of the bank’s transformation and will only gain in prominence over the coming years. Therefore, we must ensure its development adheres to principles of fairness, responsibility and transparency.”

    According to Jesús López Fidalgo, project coordinator for the University of Navarra team and head of the Institute of Data Science and AI, “responsible AI is one of the great challenges of this new era, and beyond the mere application of general ethical principles lies an open field to explore through multidisciplinary research. We excel at this type of research at the University of Navarra, which has the optimal human resources to carry it out, working alongside the team at BBVA’s Data University.”

    The virtuous triangle: technology, philosophy and regulation

    One of Fair Learning’s main avenues of research is how to mitigate the presence of bias in data. To succeed in this task, the research team will utilize advanced mathematical and statistical methods to help prevent models from learning discriminatory or biased patterns while being trained, compensate for the under-representation of certain datasets (e.g. a specific demographic group) in larger ones, and monitor the results and outputs of trained models to ensure that they do not infringe the interests of any population group.

    The team will also integrate philosophical frameworks such as human-centered AI and virtue ethics, which guide technological development based on moral criteria and social responsibility. The aim is to build systems that respect privacy, promote fairness and reinforce human autonomy without replacing it. The project will also examine how best to conduct ethical audits and establish ongoing assessment processes to ensure the continuous improvement of such systems.

    In the regulatory realm, the Fair Learning project will analyze the existing legal framework, which is built around the new European Union AI Regulation (EU AI Act), to define best practices and propose recommendations to ensure ethical and legally aligned implementation of AI systems.

    Fair Learning is part of a wider ongoing partnership between BBVA and the University of Navarra in the field of data. This relationship began in 2020 with a pioneering agreement to train the bank’s employees in data science, create a dedicated track for BBVA employees in the official Master’s in Big Data Science, and promote joint industrial PhDs between the bank and the university. To date, more than 90 students have graduated from the master’s programme, 135 data scientists have been certified, and 12 PhD students are currently enrolled, bringing the number of BBVA professionals specialized as a result of the alliance to 239. In 2024, this project reached the executive level with a Senior Management Program in Generative AI, which has already trained upward of 150 BBVA leaders in the strategic use of these technologies.

  • Sam Altman Announces New GPT-5 Features: Model Selection, Rate Limits, and Personality Tweaks

    Sam Altman Announces New GPT-5 Features: Model Selection, Rate Limits, and Personality Tweaks

    Just days after unveiling GPT-5, OpenAI CEO Sam Altman announced several new updates aimed at giving users more control and improving the AI’s performance overall. 

    In a post on X (formerly Twitter), Altman said users can now choose between three response modes: Auto, Fast and Thinking, for GPT-5. “Auto” remains the default, but the other options let people prioritise speed or deeper reasoning. 

    The latest update also sets new rate limits. Users can send 3,000 messages per week using GPT-5 Thinking. After that, they will have extra access through GPT-5 Thinking mini. The context limit for GPT-5 Thinking is now 196,000 tokens, allowing for much longer conversations and documents. 

    In response to user feedback, the GPT-4o is back in the model picker for all paid users. A new toggle in ChatGPT’s web settings will let subscribers see additional models like o3,4.1, and GPT-5 Thinking mini. The more powerful GPT-4.5 remains exclusive to Pro users due to high computing costs.

    Altman also revealed that work is underway to make GPT-5’s personality feel “warmer” without being overly chatty, a balance users said they want. He hinted at future customisation options so that people can set their preferred personality style.

     The announcement follows a rough first week for GPT-5. In a Reddit post, Altman admitted the model “felt way dumber” for several hours after an autoswitcher glitch, which is the tool that selects the best AI model for each query, went offline.  The issue has been fixed and OpenAI says the model-selection system is now smarter and will show which model is replying. 

    GPT-5 is the new AI model launched by OpenAI. The company calls it its “smartest, fastest, most useful model yet, with built-in thinking that puts expert-level intelligence in everyone’s hands.” The AI model saw a rough start with many ChatGPT fans criticising the AI model for being too flat and soulless. Many bashed the company for dropping the GPT-4 without any warning. It seems that these complaints have been heard by the company and it is now focusing on improving the experience overall.

  • Investigation of the mechanical properties of pineapple leaf fibre-reinforced biocomposites

    Investigation of the mechanical properties of pineapple leaf fibre-reinforced biocomposites

    Tensile test of PALF

    The mechanical performance of Pineapple Leaf Fibre (PALF)-reinforced polymer composites was evaluated through tensile testing, following ASTM standards for specimen preparation. The specimens were subjected to testing using an Electronic Tensometer (Model PC-2000), equipped with a 20 kN load cell, operating at a crosshead speed of 5 mm/min. A gauge length of 50 mm was maintained during the tests, which were conducted at a controlled temperature of 28 °C and 50% relative humidity. During testing, the specimens were gradually loaded until failure, and key mechanical properties such as tensile strength and elongation at break were recorded. The fracture typically occurred at the midpoint of the gauge length.

    Figure 7 illustrates the tensile testing results as a line graph, demonstrating a smooth and gradual transition of the stress-strain curve. This indicates consistent load transfer and uniform mechanical behavior between layers of the composite. The observed graph supports the hypothesis of a well-bonded and homogeneously distributed fiber-matrix interface, which ensures a continuous and reliable performance across the composite material. These characteristics are crucial for the accurate estimation of intermediate property values, confirming the robustness of the material under tensile stress.

    From the results shown in Fig. 7, it can be inferred that the composite with a 5% volume fraction of PALF reinforcement in a polyester resin matrix exhibited an ultimate tensile strength of 9 MPa. This finding is consistent with previous research, which suggests that PALF, owing to its higher aspect ratio (AR), cellulose content, and crystallinity, can significantly improve the tensile strength of composites. However, it is important to note that the hydrophilic nature of cellulose could negatively influence the tensile properties if the fiber’s moisture content is not controlled. Additionally, the incorporation of compatibilizers into the matrix has been shown to enhance the interfacial bonding between the PALF fibers and the resin. Throgh promoting a more homogeneous fiber dispersion and reducing fiber aggregation, compatibilizers improve the mechanical strength of the composite and prevent premature failure due to fiber pull-out.

    Furthermore, the uniform fiber-matrix interaction reduces the likelihood of fracture propagation within the composite, thereby enhancing the overall tensile performance. The improvements in the tensile strength and elongation at break are attributed to the effective dispersion of fibers within the matrix, which minimizes defects and stress concentrations within the material. These findings align with the results of previous studies, emphasizing the critical role of fiber treatment, matrix compatibility, and fiber orientation in determining the mechanical properties of PALF-reinforced biocomposites. The tensile testing results demonstrate that PALF-reinforced composites exhibit significant potential for use in a variety of structural applications, particularly where strength, durability, and eco-friendliness are prioritized. Further investigations into optimizing fiber treatments and resin formulations will likely yield even stronger, more versatile biocomposites.

    Elemental composition analysis using energy dispersive X-ray spectroscopy (EDS)

    Energy-dispersive X-ray spectroscopy (EDS) is a highly effective analytical technique used to determine the elemental composition of materials16. In this method, an electron beam is directed at the sample, causing the atoms within the material to emit characteristic X-rays. These emitted X-rays are captured and analyzed by an energy-dispersive detector, generating an elemental spectrum. The peaks in the spectrum are indicative of specific elements, enabling both qualitative and quantitative analysis of the sample’s composition. EDS is extensively applied in fields such as materials science, forensics, and geology, owing to its ability to provide detailed compositional information at micron to nanoscale resolutions. This makes EDS particularly valuable for tasks like trace element identification, elemental mapping, and chemical characterization of materials. Additionally, when combined with scanning electron microscopy (SEM) 17, EDS enhances the ability to investigate both the elemental composition and the morphological characteristics of the sample. The SEM results for the 2, 4, 6, and 8-layer PALF composites are presented in Fig. 8a–d, respectively.

    In this study, EDS was performed on pineapple leaf fibre (PALF) composites with varying layer configurations (2, 4, 6, 8 layers) as shown in Figs. 9, 10, 11 and 12. The analysis revealed that the composition of the PALF composites is predominantly carbonaceous, with oxygen as the next most abundant element. Trace elements such as sodium, silicon, niobium, and magnesium were also detected. The total elemental composition of the samples summed to 100.00 weight%, with one standard deviation (1 Sigma) accounting for the associated uncertainty in the measurements. These results highlight the carbon-rich nature of PALF composites, which may have significant implications for their potential applications in industries where carbon-based materials are highly valued. The precision in elemental characterization achieved through EDS plays a crucial role in material quality control and further aids in the development of these biocomposites for various engineering applications.

    The distinctive characteristics of carbon-rich pineapple leaf fibre-reinforced biocomposites (PALF) position them as a versatile and promising material with significant potential across various applications. The high carbon content within these composites is a key factor contributing to their mechanical strength and electrical conductivity, though the specific form of carbon and its arrangement within the composite matrix are critical factors influencing performance. The examination of the elemental analysis reveals a substantial carbon content in the PALF composites, suggesting potential improvements in the mechanical properties and overall durability of the material.

    With carbon constituting over 66% of the composite, the resulting material demonstrates exceptional structural strength, making it ideal for applications requiring high performance. The intrinsic rigidity and durability of carbon make it a prime candidate for reinforcement, contributing to improved tensile strength and modulus. As such, carbon-rich PALF composites possess characteristics that render them well-suited for structural applications where both lightness and strength are paramount. Examples of such applications include aerospace components, automotive parts, and biomedical equipment, where high-performance materials are essential.

    Moreover, the presence of oxygen and trace elements such as niobium and potassium adds further potential to the composite’s capabilities. Oxygen, as a functional component, may enhance the material’s compatibility with specific polymer matrices, thereby improving the bonding at the interface between the fibre and the matrix, ultimately leading to improved mechanical properties. The inclusion of niobium and potassium can also enhance specific performance traits, such as corrosion resistance and catalytic activity. These features open up additional possibilities for the use of PALF composites in industries such as chemical engineering, electronics, and environmental remediation. The high carbon content of PALF composites presents a significant opportunity for the development of advanced materials with tailored characteristics. This makes them particularly appealing for diverse industrial applications that prioritize strength, durability, and performance. The unique combination of mechanical and functional properties makes PALF composites a promising material for a wide array of applications requiring both structural integrity and specialized performance. Also, the carbon content not only carbon content alone does not directly dictate strength. Fiber orientation, matrix adhesion, and dispersion also play a crucial role in defining mechanical properties.

    Japan Bond Auction Spotlights Fragile Demand And Rate Hike Fears

    Japan’s five-year government bond auction saw the lowest demand since 2020 amid the prospect of tighter monetary policy and renewed concerns over poor market liquidity.

    The sale nudged bond prices lower across maturities from two- to 20-years, and yields on five-year securities rose as much as 3 basis points to 1.07% before easing slightly. The bid-to-cover ratio was 2.96, compared with 3.54 at the prior sale and the 12-month average of 3.74.

  • Nuclear fusion firms pledge 1,000 jobs at old Berkeley nuclear site

    Nuclear fusion firms pledge 1,000 jobs at old Berkeley nuclear site

    BBC Two men shake hands, standing on a large empty field.  Both wear blue blazers, the one on the right wears a pink shirt and has a grey beard. Behind them is an old green and brown concrete building, the former nuclear reactor.BBC

    Chris Turner (L) of Chiltern Vital Group and Bill Eden from Quantum Leap Energy are working on the plans at the former Berkeley nuclear power station

    Two nuclear energy companies have signed deals to create technology centres at a former nuclear reactor site.

    Berkeley nuclear power station in Gloucestershire was shut down in 1989, but a developer now wants to build a “nuclear centre of excellence” on the site.

    Quantum Leap Energy and Astral Systems have signed deals to set up plants there.

    Bill Eden, from Quantum Leap Energy, promised “hundreds of jobs” creating fuel for nuclear fusion.

    He said: “Nuclear fusion is now the technology of tomorrow, not of distant years.”

    Chris Turner, CEO of developers Chiltern Vital Group, said Berkeley will become “the centre of the world” in nuclear, low carbon, green technologies, and “up to 1,000” jobs would be created if the plans went ahead.

    In the shadow of the old reactor lies a maze of old buildings, mostly empty and derelict. Lying next to the River Severn at the end of a single track road, it’s a quiet place. And the former nuclear station, still being decommissioned, lends it a chilling edge.

    The man who has bought the site has big dreams. Mr Turner’s “centre of the world” comment is a bold claim, the sort many people make, so I asked him to introduce me to some real investors.

    He found two. Bill Eden works for the UK arm of American firm, Quantum Leap Energy. Like most of the firms in this venture, the technology is complex. But my basic understanding of it is that they make fuel for the nuclear fusion industry.

    “Nuclear fusion?”, I asked Mr Eden, “is that a thing yet?”

    “There is so much research going on,” he reassured me. “It needs specific fuel to make it work, and we are going to produce that here, at Berkeley.”

    He said they could be commercial within two years.

    ‘Targeted radiotherapy’

    Talmon Firestone’s tech is even harder to get to grips with. Also nuclear, but this time harnessing physics for medicine.

    “This is targeted radiotherapy,” he explains.

    “Far more effective, and far more pleasant for the patient.”

    Nuclear medicine is not new tech. Hospitals round the country use it all the time to find and treat cancer. Small amounts of radioisotopes are injected, which find their way direct to tumours. Once there, they show up under scans so the extent of disease can be identified.

    The same technology can also be used to direct radiotherapy specifically to the site of the cancer.

    But the UK has to import all the vital radioisotopes used in this medicine from reactors in Europe.

    In 2024, the supply chain was interrupted when two of them shut down for planned maintenance at the same time, and then the third sprung a fault.

    “Something like 75% of our supply was lost,” said Dr Stephen Harden, from the Royal College of Radiologists.

    “It makes a really strong case for making these radioisotopes in the UK.”

    Two men stand behind a steel tube, which is chest high. One wears a light blue shirt, the other a navy shirt. Both have beards and are smiling. The steel tube is topped with a ring of brass coloured valves. Behind them is a big green industrial building.

    Talmon Firestone (L) and Dr Tom Wallace-Smith say their new fusion reactor will supply hospitals with vital nuclear medicine materials

    Working with Dr Tom Wallace-Smith of Bristol University, Mr Firestone’s company has found a new way to make these vital nuclear ingredients, without using a big nuclear fission reactor.

    He showed me his latest array, a steel tube barely two metres tall.

    The problem is that to run his fusion reactors at full strength they need serious protection. At Berkeley, there is an old building, called C35, which is just the trick.

    “C35 has a deep bunker, created to store nuclear waste, but never actually used,” he smiled.

    “For us, it’s the perfect place to carry out our research, and then eventually produce the radioisotopes at scale.”

    A piece of steel scientific equipment stands in front of a group of scientists, some of whom wear white lab coats. There are four steel discs arranged around a central glass disc, with other equipment bolted on

    Scientists at Astral Systems labs in Bristol are using nuclear fusion to create radioisotopes used by doctors to treat cancer

    Old, unused bunkers, nuclear fusion fuel, buildings with codenames, it’s all very sci-fi.

    Mr Turner clearly relishes it all. And he has more, he says, in his nuclear pipeline.

    “We’re negotiating with the South Koreans about world-leading maritime nuclear technology.

    “We’re talking to a whole range of international companies about different nuclear and zero carbon technologies.”

    Developers always make big claims, it’s their business. Chiltern Vital Group is about to submit a planning application and then will have to deal with more mundane matters.

    Among them, how a small country road will cope with hundreds of tech workers commuting down it every day.

    Transport links needed

    The promise of new jobs was welcomed by Berkeley town councillor, Liz Ashton.

    “It will generate lots of high level tech jobs which is what we need in the area.

    But she raised concerns about the impact of the development on transport links.

    “There are lots of problems regarding the motorway junctions. They really need to revive a good public transport system, so people won’t be coming in their cars.”
