MIT researchers developed ShiftLens, a 3D-printing system that creates interactive objects whose surfaces change appearance mechanically, without electronics.

Katherine Rundell argues that the struggle involved in reading, writing, and thinking is part of education itself, and asks what is lost when generative AI removes that struggle.

Original article The Guardian: https://www.theguardian.com/technology/2026/aug/11/ai-will-do-more-to-boost-fossil-fuel-production-than-green-energy Introduction This article examines a policy tension: AI can improve renewable-energy systems, but it can also increase the productivity of oil and gas extraction. The study models 64 scenarios and argues that indirect effects across the energy system may matter more than focusing only on AI data-center electricity consumption. Vocabulary outweigh — be greater in importance or effect; productivity gain — increase in output or efficiency; fossil fuel — coal, oil, or natural gas; renewable energy — energy from replenishable sources; carbon emissions — release of carbon dioxide; optimize — make more efficient; deployment — practical implementation; at scale — at large operational size; pilot project — small preliminary implementation; adoption — taking up a technology; outpace — grow faster than; break even — reach a balance; speculative — based partly on uncertain assumptions; unchecked — not adequately controlled. ...

Original article Mark Zuckerberg, The Wall Street Journal: https://www.wsj.com/opinion/the-ai-future-is-for-everyone-technology-meta-superintelligence-8c3e34dc Introduction Zuckerberg argues that advanced AI should primarily empower individuals rather than concentrate capability in a small number of institutions. The essay emphasizes broad access, invention, entrepreneurship, and personal agency. It is especially useful for IELTS critical reading because it presents a clear technology-industry viewpoint whose assumptions can be examined separately from its claims. Vocabulary empowerment — giving people greater ability or control. prosperity — a state of economic success and wellbeing. superintelligence — intelligence that greatly exceeds ordinary human capability in many domains. distribute — spread something across many people or places. invention — creation of something new. automation — use of technology to perform work with less direct human effort. entrepreneurship — creating and developing new businesses. balance of power — distribution of influence among competing actors. open source — software or technology whose source is openly available under its license. concentrate power — place disproportionate control in a small number of hands. accessibility — how easily something can be reached or used. potential — capacity to develop or achieve something in the future. Reading comprehension 1. Why does Zuckerberg argue that advanced AI should be widely accessible? ...

Original article The Rockefeller University: https://www.rockefeller.edu/news/36993-study-reveals-how-unexpected-shifts-in-cell-populations-are-revising-our-understanding-of-the-aging-process/ Introduction Researchers profiled more than 21 million cells from major mouse organs across different life stages. They found coordinated expansions and declines in particular cell populations, suggesting that aging may involve stage-like biological transitions rather than only a smooth accumulation of random damage. Vocabulary wear and tear — gradual damage caused by long-term use or exposure. haphazard — lacking an organized pattern. deterioration — gradual decline in quality or function. prevailing — currently dominant or widely accepted. daunting — difficult enough to seem intimidating. high-throughput — able to process very large numbers of samples quickly. quantify — measure numerically. depletion — a substantial reduction in amount or number. vulnerable — especially likely to be harmed or affected. proliferate — increase rapidly in number. abrupt — sudden rather than gradual. susceptibility — likelihood of being affected by a condition. regenerative capacity — ability of tissue to repair or renew itself. intervention — an action intended to alter an outcome. Reading comprehension 1. Why do the findings challenge a simple “wear and tear” model of aging? ...

Original article The Guardian: https://www.theguardian.com/science/2026/aug/12/astronomy-discovery-new-cosmic-object-black-hole-star Introduction Astronomers using the James Webb Space Telescope identified an object that looks star-like but is far too luminous to be powered by ordinary stellar fusion. The leading explanation is a black hole surrounded by an extremely dense envelope of gas — a “black hole star” that could help explain JWST’s mysterious little red dots. Vocabulary mashup — a combination of different things. nascent — newly formed or at an early stage. enshrouded — completely surrounded or covered. accretion — gradual accumulation of material around a massive object. intrinsic — belonging naturally to the object itself. spectral — relating to the distribution of light by wavelength. wavelength — the distance between successive waves of light. rule out — eliminate as a possible explanation. distinctive — clearly different and recognizable. cocoon — an enclosing layer; here, dense gas around a black hole. incorporate — include as part of a model or system. parameter — a value that defines part of a model. outshine — appear much brighter than something else. plausible explanation — an explanation that is reasonably believable. Reading comprehension 1. Why is the object described as a “black hole star”? ...

Original article MIT AeroAstro: https://aeroastro.mit.edu/news-impact/interactive-causal-diagram-of-habitat-design-impacts-on-behavioral-health-and-performance-in-extreme-environments/ Introduction Long-duration missions to the Moon and Mars require habitats that support not only physical survival but also behavioral health and crew performance. MIT researchers use a Directed Acyclic Graph (DAG) to map how habitat-design choices can influence human outcomes in isolated, confined, and extreme environments. Vocabulary habitat — an environment designed for people or organisms to live in. thrive — develop and function well, rather than merely survive. wellbeing — overall physical and mental health. isolation — separation from other people or normal surroundings. cohesion — the ability of a group to remain connected and cooperative. reconfigurable — able to be rearranged for different uses. intervention — an action intended to improve a situation. mitigate — reduce the severity of a negative effect. circadian rhythm — the body’s roughly 24-hour sleep-wake cycle. downstream effect — a later consequence caused by an earlier factor. constraint — a limitation that restricts available choices. human-centered — designed around human needs and behavior. causal relationship — a relationship in which one factor contributes to producing another. austere — difficult, restricted, or lacking normal comforts. Reading comprehension 1. Why is physical survival alone not enough when designing long-duration space habitats? ...

Original article MIT Lincoln Laboratory: https://www.ll.mit.edu/news/high-orbit-satellites-could-light-way-travel-moon Introduction The LightHOUSE concept proposes cooperative optical beacons in very high Earth orbits to provide GPS-like navigation and communications for spacecraft in cislunar space.
