Essay aid or cognitive crutch? MIT study tests the cost of writing with AI
While LLMs reduce cognitive load, a new study warns they may also hinder critical thinking and memory retention - raising concerns about their growing role in learning and cognitive development Rahul Goreja New Delhi A new study from the Massachusetts Institute of Technology (MIT) Media Lab has raised concerns about how artificial intelligence tools like ChatGPT may impact students' cognitive engagement and learning when used to write essays. The research, led by Nataliya Kosmyna and a team from MIT and Wellesley College, examines how reliance on large language models (LLMs) such as ChatGPT compares to traditional methods like web searches or writing without any digital assistance. Using a combination of electroencephalogram (EEG) recordings, interviews, and text analysis, the study revealed distinct differences in neural activity, essay quality, and perceived ownership depending on the method used. Note: EEG is a test that measures electrical activity in the brain. Setup for cognitive engagement study 54 participants from five Boston-area universities were split into three groups: those using only ChatGPT (LLM group), those using only search engines (search group), and those writing without any tools (brain-only group). Each participant completed three writing sessions. A subset also participated in a fourth session where roles were reversed: LLM users wrote without assistance, and brain-only participants used ChatGPT. All participants wore EEG headsets to monitor brain activity during writing. Researchers also interviewed participants' post-session and assessed essays using both human markers and an AI judge. Findings on neural engagement Electroencephalogram (EEG) analysis showed that participants relying solely on their own cognitive abilities exhibited the highest levels of neural connectivity across alpha, beta, theta, and delta bands — indicating deeper cognitive engagement. In contrast, LLM users showed the weakest connectivity. The search group fell in the middle. 'The brain connectivity systematically scaled down with the amount of external support,' the authors wrote. Notably, LLM-to-Brain participants in the fourth session continued to show under-engagement, suggesting a lingering cognitive effect from prior LLM use. Essay structure, memory, and ownership When asked to quote from their essays shortly after writing, 83.3 per cent of LLM users failed to do so. In comparison, only 11.1 per cent of participants in the other two groups struggled with this task. One participant noted that they 'did not believe the essay prompt provided required AI assistance at all,' while another described ChatGPT's output as 'robotic.' Essay ownership also varied. Most brain-only participants reported full ownership, while the LLM group responses ranged widely from full ownership to explicit denial to many taking partial credit. Despite this, essay satisfaction remained relatively high across all groups, with the search group being unanimously satisfied. Interestingly, LLM users were often satisfied with the output, even when they acknowledged limited involvement in the content's creation. Brain power trumps AI aid While AI tools may improve efficiency, the study cautions against their unnecessary adoption in learning contexts. 'The use of LLM had a measurable impact on participants, and while the benefits were initially apparent, as we demonstrated over the course of four months, the LLM group's participants performed worse than their counterparts in the Brain-only group at all levels: neural, linguistic, scoring,' the authors wrote. This pattern was especially evident in session four, where brain-to-LLM participants showed stronger memory recall and more directed neural connectivity than those who moved in the opposite direction. Less effort, lower retention The study warns that although LLMs reduce cognitive load, they may diminish critical thinking and reduce long-term retention. 'The reported ownership of LLM group's essays in the interviews was low,' the authors noted. 'The LLM undeniably reduced the friction involved in answering participants' questions compared to the search engine. However, this convenience came at a cognitive cost, diminishing users' inclination to critically evaluate the LLM's output or 'opinions' (probabilistic answers based on the training datasets),' it concluded.

Hack-proof communication? DRDO, IIT Delhi test quantum message technology
The defence ministry said that this form of communication can support applications such as long-distance quantum key distribution, secure data transmission, and the development of quantum networks Rahul Goreja New Delhi The Defence Research and Development Organisation (DRDO) and the Indian Institute of Technology (IIT) Delhi have successfully tested quantum secure communication over a free-space optical link, the Ministry of Defence said in a statement on Monday. What is quantum secure communication? Quantum secure communication is a technique for transmitting information that is considered theoretically impossible to hack. How does it work? It uses the principles of quantum physics — specifically quantum entanglement, where two particles remain connected regardless of distance. If someone tries to intercept or eavesdrop on the communication, the quantum state changes, immediately alerting the sender and receiver that the message has been compromised. The test The test was carried out by the DRDO–Industry–Academia Centre of Excellence (DIA-CoE) at IIT Delhi, where a secure quantum key was transmitted using entangled photons over a distance of more than one kilometre on the IIT Delhi campus. The experiment achieved a secure key rate of around 240 bits per second, with a quantum bit error rate of less than 7 per cent, the ministry said. 'India entered into a new quantum era of secure communication which will be a game changer in future warfare,' said Defence Minister Rajnath Singh, congratulating the DRDO and IIT Delhi on the achievement. The uses According to the ministry, this form of communication can support applications such as long-distance quantum key distribution (QKD), secure data transmission, and the future development of quantum networks. The work was conducted under the DRDO-funded project titled Design and development of photonic technologies for free space QKD. The demonstration was led by Professor Bhaskar Kanseri's research group and attended by senior officials from DRDO and IIT Delhi. Quantum entanglement-based QKD enables users to detect any attempt to intercept or alter the communication, since such actions would disturb the quantum state of the transmitted particles. This method can be used even when devices are not fully trusted or are imperfect, the ministry said. Unlike traditional fibre-based QKD systems, free-space QKD does not require the installation of optical fibre networks, which can be costly or impractical in some areas. Why is this important? This development is expected to support the creation of quantum-encrypted networks and contribute to the emergence of a 'quantum internet,' where devices communicate via highly secure quantum connections. These advances are likely to enhance cybersecurity, improve the protection of sensitive data, and influence secure communications across various sectors. The demonstration also carries important implications for military and national security by enhancing secured communication.

RCB moves Karnataka High Court to quash FIR in Chinnaswamy stampede case
A massive crowd had gathered outside the stadium on June 4 to celebrate RCB's historic first-ever IPL title. However, the event turned tragic when a stampede broke out, killing 11 people Rahul Goreja New Delhi IPL 2025 champions Royal Challengers Bengaluru (RCB) on Monday moved the Karnataka High Court, seeking to quash the criminal case against it in relation to the stampede at Bengaluru's M Chinnaswamy Stadium that claimed the lives of 11 people. In its petition, the Royal Challengers Sports Limited (RCSL), owner of the franchise, has claimed that it has been falsely implicated in the case as it had already communicated on social media that only limited passes are available for the event, reported PTI. RCSL also alleged that the stadium gates, which were supposed to open at 1.45 pm, were actually opened only at 3 pm, causing a crowd surge. Meanwhile, DNA Entertainment Networks Pvt Ltd, the event organiser at the venue, has also filed a petition against the FIR. It claimed that the stampede occurred due to failure of crowd management by the police. What happened at Chinnaswamy Stadium? A large crowd assembled outside Bengaluru's M Chinnaswamy Stadium on June 4 to mark Royal Challengers Bengaluru's maiden IPL championship. The celebration, however, ended in tragedy when a stampede occurred, leaving 11 people dead and 33 others injured. According to Karnataka Chief Minister Siddaramaiah, the stampede occurred near a small stadium gate overwhelmed by the crowd. "A large number of people gathered there and broke it, which led to the stampede," he said, adding that most victims were young. Deputy Chief Minister DK Shivakumar said the programme was shortened in response to the crowd surge. "We appeal to the people to remain calm. The programme ended within 10 minutes. We are trying to make everything normal... Lakhs of people came," he said. Following the incident, an FIR was lodged against Royal Challengers Bengaluru (RCB), event organiser DNA Entertainment Networks, the Karnataka State Cricket Association (KSCA), and other parties. Government announces inquiry and financial relief Chief Minister Siddaramaiah also announced a judicial inquiry into the incident, to be led by retired High Court judge Justice Michael D'Cunha. The state government also said ₹10 lakh compensation will be given for each of the victims' families. Meanwhile, RCB has also announced ₹10 lakh financial aid for the families of the deceased.

CDS visits border bases, lauds armed forces after Operation Sindoor
During his visit to bases in Gujarat and Rajasthan, General Anil Chauhan praised the high morale and joint preparedness of troops for their role in Operation Sindoor Rahul Goreja New Delhi The Chief of Defence Staff (CDS), General Anil Chauhan, on Monday commended the operational preparedness and high morale of the Indian armed forces during his visit to the Suratgarh Military Station in Rajasthan and Naliya Air Force Station in Gujarat. The visit was held in recognition of the courage shown by soldiers during Operation Sindoor, in which India targeted nine terrorist sites in Pakistan and Pakistan-occupied Jammu & Kashmir (PoJK) in response to the Pahalgam attack last month. 'They uphold the highest standards of military professionalism,' General Chauhan said, lauding their 'exceptional valour and professionalism' during the active phase of Operation Sindoor. During the visit, the CDS interacted with the troops and emphasised the importance of maintaining operational readiness and resilience amid evolving security challenges. He was accompanied by Lieutenant General Manjinder Singh, Army Commander of the South Western Command, and Air Marshal Nagesh Kapoor, Air Officer Commanding-in-Chief of the South Western Air Command. Defence personnel also briefed the CDS on the deployment of the latest and robust air defence systems used during the operation and held strategic discussions with senior military commanders on-site. Highlighting the importance of joint force operations, the CDS praised the synergy between the Army and the Air Force, stating the need 'to remain ever prepared for responding to any challenge with decisive force.' Operation Sindoor Tensions between India and Pakistan escalated sharply following the April 22 Pahalgam terror attack, which left 26 people dead. Investigations linked the attack to terror outfits operating from Pakistan and PoJK. Following these operations, Pakistan retaliated with drone and missile strikes targeting western India, which were intercepted by Indian defence systems. India responded with precision strikes on military targets deep within Pakistani territory. The escalation prompted global concern, but the two countries agreed to a ceasefire on May 10, bringing an end to four days of intense military engagement.
