Big Tech companies are reportedly assessing physical security risks tied to the escalating conflict with Iran, with the Strait of Hormuz identified as the center of the crisis. The situation is having an immediate impact on global markets and raising concerns about energy supplies, adding infrastructure and personnel risks to the industry's war-related worries.

Union Minister Ashwini Vaishnaw has warned that India's semiconductor ambitions will face cyberattacks, fake news campaigns and even physical attacks as the country expands its chip manufacturing push. Citing past incidents during Apple's rollout in India, including cut power lines and deliberate food poisoning of workers, he said sabotage attempts should be expected and that the government is prepared to counter them.

At least a dozen Chinese banks plan to wind down their retail leveraged precious-metals trading services, according to a widely shared report. The move restricts retail investors' access to leveraged gold and silver products at a time when demand for physical precious metals in China is described as surging.

Physicists report creating a record-breaking Schrödinger's cat state, a quantum superposition in which atoms exist in two states at once, using some of the most unusual atoms in physics. The experiment pushes the known limits of how large an object can be while remaining in a quantum superposition, a milestone for quantum physics research.

Scientists have developed the most accurate atomic clock ever built, according to a newly published report. The clock advances precision timekeeping, which underpins GPS navigation, telecommunications and tests of fundamental physics. Researchers say such devices lose tiny fractions of a second over billions of years, pushing the limits of measurement science and potentially prompting a redefinition of the second itself.

A new Brookings Institution study examines the enormous physical footprint of the AI boom, from specialized chips and electricity demand to purpose-built data centers, noting that two-thirds of a data center's cost can go into hardware and construction. 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.

A new report examines how major technology companies are confronting physical security risks tied to the ongoing conflict involving Iran. The analysis also assesses Iran's broader political, economic, and military resilience, and outlines the limits of US military power in the Middle East as the war continues.

Researchers are presenting new imaging techniques that combine artificial intelligence with physics-based methods, enabling tasks such as seeing what is hidden from view and automatically adding color to anime footage. The work, described in a science news release, suggests these approaches could shape how imaging technology develops, with potential uses in science, media and visual restoration.

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.

Ukraine has announced a large-scale programme to build an 'army of robots', described by officials as a 'Manhattan Project for physical AI'. The initiative aims to develop autonomous ground and aerial systems at scale for battlefield use, drawing comparisons to the World War Two atomic research effort. The announcement has drawn international attention given Ukraine's ongoing war with Russia and the growing role of drones and robotics in modern combat.

Ukrainian official Koretskyy has described how the country is preparing to defend its internet infrastructure against Russian attacks. He outlined measures to protect networks and connectivity amid continued cyber and physical threats stemming from the war. The remarks have drawn attention among readers following Ukraine's digital security efforts.

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.

New research highlights that people living with severe mental illness die more than 10 years earlier than the general population. Researchers point to contributing factors behind the gap, which is widely attributed in the field to physical health conditions going undertreated, higher rates of smoking and cardiovascular disease, medication side effects, and poorer access to healthcare. The finding has renewed calls to close the life-expectancy gap for this group.

Thousands of protesters blocked a road in Northern Ireland to stop an Orange Order march from entering a Catholic area. Demonstrators gathered along the route as the traditional parade attempted to pass, forcing a halt. The confrontation has drawn attention to long-standing tensions over parades, with critics viewing the marches as provocative and defenders describing them as cultural expressions of Protestant heritage.

An AI researcher is warning that the most serious threat from artificial intelligence is not sci-fi scenarios of robot armies, but the gradual erosion of democratic institutions. The argument is that AI-driven misinformation, surveillance and concentration of power could undermine elections and public debate long before any physical danger materialises. The warning adds to a growing debate about whether AI policy should focus on existential risks or on protecting civic and democratic life.

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.

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.

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.

New research suggests chronic loneliness may shorten a person's healthy lifespan by close to six years, underscoring the physical toll of social isolation. The finding has sparked discussion about loneliness as a serious public health concern, comparable to established risk factors, and about the need to treat social connection as part of preventive healthcare.

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.

Researchers have used a quantum computer to simulate how matter can emerge from pure energy, a process linked to pair production in which energetic particles such as photons convert into particle-antiparticle pairs. The demonstration shows how quantum hardware can model fundamental physics processes that are extremely difficult to capture with classical computers, offering a new tool for studying high-energy phenomena.

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. The episode ties together the environmental cost of the AI boom with fundamental physics and biology discoveries, offering a snapshot of current conversations across science news.
