The report assesses how large the buildout has become and what financial and economic risks it may pose if AI investment slows or falls short of expectations.

Researchers report observing how an aggressive brain cancer physically remodels brain tissue as it grows, offering a live view of tumor progression. The findings shed light on how deadly brain tumors invade and distort surrounding structures, which could inform future treatment approaches. The work is drawing attention for its striking visualization of the disease's effects on the brain.

Bloomberg reports that driverless trucks may provide a model for how autonomous AI systems can be deployed safely without harming people. The argument is that self-driving freight has operated under strict testing, regulation and limited-use conditions, offering a template for governing more advanced robots. The piece adds to ongoing debate about how to manage AI risks as automation expands into physical industries.

Novak Djokovic has given an update on his fitness ahead of his return to Beijing and spoken about the passionate support he receives from fans in China, known as his 'NoleFam'. The Serbian star addressed his physical condition as he prepares to compete at the tournament in the Chinese capital, highlighting his popularity among Chinese supporters.

An AI-based analysis of data from the Large Hadron Collider is challenging the theory that the universe contains ten dimensions, according to a report by RBC-Ukraine. The study suggests the extra dimensions predicted by string theory may not exist, prompting debate among physicists about the foundations of the model and how machine learning should be used to test fundamental physics.

Researchers report a technique for reshaping light to control magnetic memory and adjust a material's magnetic properties. The advance could point toward faster, more efficient data storage, since it suggests magnetism in certain materials can be manipulated optically rather than only with electric currents or magnetic fields. Details of the method and its practical applications have not been widely reported yet.

Gecko Robotics' chief executive is arguing that humans must remain in control as artificial intelligence moves into the physical world through robots and industrial automation. The company builds robots used to inspect critical infrastructure such as bridges, power plants and pipelines. The intervention adds a robotics industry voice to the ongoing debate over how much autonomy should be granted to AI-driven machines in safety-critical settings.

Researchers subjected water to light roughly 10 billion times more intense than sunlight, expecting evaporation to speed up dramatically. Instead, the water's evaporation rate barely changed, defying the straightforward expectation that more light energy means faster evaporation. The surprising result has drawn attention in physics circles, raising questions about how energy moves through water at extreme intensities and what invisible processes may be limiting evaporation.

A Quanta Magazine article explaining the holographic principle in physics is being discussed on Hacker News. The idea is that gravity in a volume of space can be described by information encoded on that volume's boundary, as in the AdS/CFT correspondence, suggesting three-dimensional reality may emerge from lower-dimensional information. Commenters on the post are debating what this implies about the fundamental nature of space, time and whether reality is a projection.

China has reportedly reached a new milestone with an advanced super microscope, a development being framed as potentially significant for science and technology. The claim has circulated through physics-focused news outlets, though few details about the instrument, its capabilities, or the research it enables are available. Observers are watching to see what the advance could mean for fields that depend on high-resolution imaging.

The Pentagon is asking for $30.3 million over five years to develop an AI-powered lie detection system that can analyze body language remotely, without physical contact. The program, called Polygraph Next, is included in the Defense Counterintelligence and Security Agency's 2027 budget request. Commenters are raising concerns about the privacy implications and scientific reliability of automated deception detection, noting that traditional polygraph accuracy is already contested.

Scientific American's latest science roundup covers the rising energy demands of artificial intelligence, ongoing efforts to detect subatomic particles, and research into an amoeba that thrives at extreme temperatures.
