In a test of the examinations system of the University of Reading in the UK, artificial intelligence (AI)-generated submissions went almost entirely undetected, and these fake answers tended to receive higher grades than those achieved by real students. Peter Scarfe of the University of Reading and colleagues present these findings in the open-access journal PLOS ONE on June 26.
In recent years, AI tools such as ChatGPT have become more advanced and widespread, leading to concerns about students using them to cheat by submitting AI-generated work as their own. Such concerns are heightened by the fact that many universities and schools transitioned from supervised in-person exams to unsupervised take-home exams during the COVID-19 pandemic, with many now continuing such models. Tools for detecting AI-generated written text have so far not proven very successful.
To better understand these issues, Scarfe and colleagues generated answers that were 100% written by the AI chatbot GPT-4 and submitted on behalf of 33 fake students to the examinations system of the School of Psychology and Clinical Language Sciences at the University of Reading. Exam graders were unaware of the study.
Today we’re releasing early access to Gemini 2.5 Pro Preview (I/O edition), an updated version of 2.5 Pro that has significantly improved capabilities for coding, especially building compelling interactive web apps. We were going to release this update at Google I/O in a couple weeks, but based on the overwhelming enthusiasm for this model, we wanted to get it in your hands sooner so people can start building.
This builds on the overwhelmingly positive feedback to Gemini 2.5 Pro’s coding and multimodal reasoning capabilities. Beyond UI-focused development, these improvements extend to other coding tasks such as code transformation, code editing and developing complex agentic workflows.
NASA’s Gateway project takes a major leap as the HALO module, a future home for Artemis astronauts, arrives in Arizona for final outfitting. With life support, command systems, and thermal controls being installed, HALO is preparing to serve as a critical link for lunar exploration. Excitement ma
New research led by Imperial College London and co-authored by the University of Bristol, has revealed that aerial robotics could provide wide-ranging benefits to the safety, sustainability and scale of construction.
The research examines the emerging field of using drones for mid-air material deposition in the construction industry —a process known as Aerial Additive Manufacturing (Aerial AM).
This technology addresses pressing global housing and infrastructure challenges using aerial robots equipped with advanced manipulators that can overcome the limitations of traditional construction methods and ground-based robotic systems.
A new AI robot called π-0.5 uses 100 decentralized brains, known as π-nodes, to control its body with lightning-fast reflexes and smart, local decision-making. Instead of relying on a central processor or internet connection, each part of the robot—like fingers, joints, and muscles—can sense, think, and act independently in real time. Powered by a powerful vision-language-action model and trained on massive, diverse data, this smart muscle system allows the robot to understand and complete real-world tasks in homes, even ones it has never seen before.

Addressing the challenges of fragrance design, researchers at the Institute of Science Tokyo (Science Tokyo) have developed an AI model that can automate the creation of new fragrances based on user-defined scent descriptors. The model uses mass spectrometry profiles of essential oils and corresponding odor descriptors to generate essential oil blends for new scents.
This advance could be a game-changer for the fragrance industry, moving beyond trial-and-error to enable rapid and scalable fragrance production. The findings are published in IEEE Access.
Designing new fragrances is crucial in industries like perfumery, food, and home products, where scent significantly influences the overall experience of these products. However, traditional fragrance creation can be time-consuming and often depends on the skill and expertise of specialized perfumers. The process is typically challenging and labor-intensive, requiring numerous trial-and-error attempts to achieve the desired scent.
And its already removed over 84,000 kg of ocean trash.
The Ocean Cleanup, a non-profit environmental organization, has embarked on a groundbreaking mission to eliminate 90% of floating ocean plastic by 2040.
Through innovative technology and a two-pronged approach—removing plastic already polluting the oceans and intercepting new waste in rivers—the project is making real progress.
Their ocean cleanup systems, including the latest System 3, are actively harvesting waste from the Great Pacific Garbage Patch, while river-based Interceptors are stopping plastic at the source in high-impact areas like Southeast Asia and the Caribbean.
With over 84,000 kilograms of plastic removed and more than 2,700 square kilometers of ocean cleaned as of mid-2022, The Ocean Cleanup has already made significant strides. Backed by scientific research, partnerships with companies like Coca-Cola and Maersk, and global support, the organization is scaling up its efforts. Targeting the world’s 1,000 most polluting rivers, The Ocean Cleanup aligns closely with the United Nations’ Sustainable Development Goal 14—conserving marine life. Through technology, collaboration, and determination, they’re turning the tide on ocean pollution.
