Musk Lays Claim to Redefine Human Knowledge with AI
Elon Musk has disclosed plans to overhaul xAI's conversational system Grok by essentially reconstructing its entire knowledge foundation. Frustrated with what he describes as 'garbage' and 'uncorrected data' in the model, Musk intends to launch Grok 3.5—potentially rebranded as Grok 4—with enhanced reasoning capabilities that will first re-write the entire corpus of human knowledge before retraining the model on that curated dataset. Musk wilted no words on X, characterising the endeavour as necessary to purge errors and integrate missing information—a process he says will counter the mainstream constraints he believes afflict existing AI systems. He also solicited 'divisive facts' from users—material that is politically incorrect yet supposedly factual—to enrich training, a move that elicited responses including Holocaust denial claims and conspiracy narratives. Experts have raised alarms about the proposal. Gary Marcus, professor emeritus at New York University, warned that the plan evokes a totalitarian impulse, likening it to Orwellian efforts to rewrite history for ideological alignment. Other ethicists emphasise that any attempt to curate a knowledge base to reflect particular values risks embedding hard‑to‑detect bias through subtle manipulation—what some describe as 'data poisoning'—even more insidiously than overt interventions. ADVERTISEMENT Grok's performance history reveals why Musk may feel compelled to act. Earlier this year, an 'unauthorised modification' led the model to spontaneously reference a conspiracy theory known as 'white genocide' in South Africa—often in contexts unrelated to the topic—raising significant concerns about its reliability. That glitch prompted xAI to launch an internal review and reinforce measures to increase the bot's transparency and stability. Institutional interest in Grok continues despite these setbacks. Sources told Reuters that entities such as the US Department of Homeland Security have been testing the system for data analysis and reporting, though officials clarified no formal endorsement has been issued. The proposed timeline for deploying Grok 3.5 or Grok 4 is expected by late 2025, with Musk pivoting xAI's effort away from public scrutiny and more towards curated, Musk‑aligned content. Critics caution that this shift could entrench a corporate agenda within the core of the AI, producing outputs that reflect ideological preferences rather than objective accuracy. This initiative occurs against a backdrop of broader AI regulation efforts. While governments wrestle with proposals ranging from state-level moratoria to risk-based frameworks, the question of how AI systems calibrate values remains contested. Musk's move intensifies that debate: will AI be a vessel for neutral knowledge, or a tool shaped—perhaps weaponised—by powerful individuals? The discussion now centers on transparency and accountability. Analysts argue that redefining a model's data foundation under the stewardship of a single corporate leader demands oversight mechanisms akin to those in utilities or public infrastructure. Ethical guidelines suggest dataset documentation, traceability, and multi‑stakeholder governance are essential to mitigate risks of ideological capture. Academic work on 'model disgorgement' offers technical approaches to remove or correct problematic knowledge, but experts emphasise that full transparency remains practically elusive at scale. Musk's declaration marks a turning point not just for Grok, but for the trajectory of AI governance. It anticipates a future in which elite designers may directly shape the content of civilisation's shared memory. As work begins on this ambitious rewrite, key questions emerge: who determines what qualifies as 'error'? Who adjudicates 'missing information'? And how will the public ensure that history remains a mosaic of perspectives, not a curated narrative?

Sun unleashes powerful flares as it approaches its most active phase
The Sun has been unusually active this past week, sending out powerful bursts of energy known as solar flares, which have disrupted radio signals and created stunning auroras across parts of North America and Europe. Scientists say this is a sign that the Sun is nearing the peak of its natural 11-year cycle, known as the solar maximum, which had been forecast to take place in July. In recent days, the Sun has emitted several strong flares and enormous clouds of charged particles known as coronal mass ejections. One particularly powerful flare on June 17, classified as X-class, the strongest type, caused brief radio blackouts in North America, with warnings issued for satellites and astronauts in orbit. The Sun unleashed an even stronger X1.9-class flare on June 19, causing radio blackouts over parts of the US and Pacific region. As the Sun nears solar maximum, there is an increase in sunspots and energy bursts that can sometimes be directed towards Earth. Katepalli Raju Sreenivasan, a scientist at New York University Abu Dhabi, said that while solar activity is expected to peak sometime in the next few months, 'no one knows exactly when'. 'It is not going to be especially violent activity this year, so I don't expect any unprecedented damage to Earth's communication infrastructure,' he told The National. 'But I should also say that what matters to us is not necessarily the magnitude of the solar activity but whether one or two of the highly energetic emissions from the Sun reach the Earth. Most, of course, pass by without any effect.' Most of the time, these events do indeed miss Earth or only cause minor effects. But when a strong burst of solar energy is aimed directly at the planet, it can trigger geomagnetic storms, which are powerful disturbances that impact satellites, radio communication, GPS and power grids. Dr Mojtaba Akhavan-Tafti, a space scientist at the University of Michigan, explained the science behind it. 'Solar activity peaks at the solar max because of the increasing number of active spots on the Sun, which are associated with strong releases of magnetic and charged particle energies into the interplanetary environment,' he said. While this can cause disruptions to technology, it also leads to one of the most beautiful natural phenomena – Northern and Southern Lights, or Aurora. 'On the bright side, increased geo-effective phenomena means more chances of observing the mesmerising Northern Lights over the next couple of years,' he said. 'On the other side, heightened geo-effective space weather threatens our technological civilisation, from space-borne assets and the life of astronauts in orbit due to increased space radiation levels, as well as ground-based technologies including communication and power grid platforms due to increased electromagnetic disturbances.' A reminder from history Solar storms have affected Earth in the past. The most powerful on record took place in 1859, known as the Carrington Event, which disrupted telegraph systems and lit up skies around the world with bright auroras. If a storm of that magnitude happened today, it could severely damage satellites, knock out internet and GPS systems and disrupt power supplies in major cities. In 1989, a solar storm caused a blackout for six million people in Quebec, Canada. In 2003, a series of flares damaged satellites and forced airlines to reroute flights away from polar regions due to radiation risks. Watching the Sun closely To stay prepared, space agencies such as Nasa and the European Space Agency are using satellites to monitor the Sun around the clock. Missions s the Parker Solar Probe and Soho (Solar and Heliospheric Observatory) help scientists understand what is coming and give warning before a storm hits Earth. Nasa's Parker Solar Probe became the first human-made object to 'touch the Sun', when it flew through the sun's upper atmosphere to sample particles and magnetic fields in 2021. It beat its own record in 2024 when it made another close approach to the Sun, reaching 6.1 million kilometres from the Sun's surface. The spacecraft also achieved a record-breaking speed of 692,000 kilometres per hour during this fly-by.

UAE: Disease testing in 10 minutes? Abu Dhabi scientists develop affordable tool
A team of scientists at New York University Abu Dhabi has developed a paper-based diagnostic device that can detect infectious diseases in under 10 minutes. The Radially Compartmentalised Paper Chip (RCP-Chip) offers a fast, affordable, and portable solution for on-site screening of infectious diseases without the need for sophisticated lab equipment or trained personnel. Conceived during the early days of the Covid pandemic, the RCP-Chip was designed to address the urgent global need for efficient testing in low-resource and remote settings. 'Our goal was to create something fast, affordable, and easy to use, especially in areas where lab access is limited,' said Mohammad A. Qasaimeh, Associate Professor of Mechanical Engineering and Bioengineering at NYUAD and the senior author of the study. Beyond Covid-19, the chip is easily reconfigurable to test for other viruses and bacteria which causes diseases like chickenpox, dengue and malaria. 'With minor modifications, it can be adapted to diagnose a wide range of diseases or even test hormones and metabolites,' he explained. 'What makes it truly impactful is its real-world potential,' said Pavithra Sukumar, NYUAD Research Assistant and co-first author. 'This portable test could significantly improve outbreak response by enabling faster isolation, treatment, and control.' How it works According to Qasaimeh, the handheld device can be mass-produced and utilised in places where resources are limited. 'It requires minimal number of reagents and sample to run,' he said. 'It needs a heating stage which is around 60 degrees Celsius. This can be achieved by means of a hot plate or an oven. These are commonly founded devices everywhere.' It uses saliva instead of swabs and can be sent to any area very quickly. 'In a short amount of time, you can deploy it for use,' he said. 'That was our other motivation when we were developing it.' Qasaimeh added that it took the team approximately two years to develop due to pandemic-related lab access restrictions. 'In the initial phase, we focused on designing the chip and brainstorming the approaches,' he said. 'After initial curfews, gradually they allowed us to have access to the labs. That is when we started testing the device and deepened the research.' The team has filed a patent and launched a startup to pursue commercialisation, with interest already shown by biotech firms. 'We aim to find investors so that we can continue with the development stage of the device, but this time with its translational potential,' said Qasaimeh. 'This is so that the device is ready to deploy in the markets for different purposes. This device can be modified to be used for other situations as well.'
