What did the study find?
24 received stimulation to the dorsolateral prefrontal cortex,
24 had stimulation to the posterior parietal cortex (an area involved in processing sensory information),
24 received a fake (placebo) treatment.

A new study from the University of Surrey, UK, has found that applying gentle electric currents to the brain can help young adults solve maths problems better and faster.Researchers used a technique called transcranial random noise stimulation , which involves sending weak, safe electric currents through the scalp to a part of the brain known as the dorsolateral prefrontal cortex . This area, located behind the forehead, plays a key role in learning, memory, and focus.The study involved 72 participants aged between 18 and 30. They took part in a five-day maths training programme. Out of these:The results showed that those with weak natural connections between the two brain regions, the dorsolateral prefrontal cortex and the posterior parietal cortex, improved significantly when given brain stimulation. Those with strong natural connections performed well even without stimulation.Brain scans revealed that people with better brain connectivity in these regions performed better in maths. The stimulation appeared to help people with weaker brain links catch up. Improvements were also linked to lower levels of a brain chemical called GABA, which helps with learning and memory by stabilising new information.Lead researcher Roi Cohen Kadosh said that while most education systems focus on things like better teaching and updated curricula, the brain's biology is often ignored. 'By understanding how the brain works during learning, we can develop new methods to support more people in reaching their potential,' he said.The study, published in PLOS Biology, adds to growing research on how brain stimulation could be used safely to support learning, especially in key subjects like maths.Inputs from PTI

Delhi HC asks DGCI to decide representation over weight-loss drugs
A plea filed by Jitendra Chouksey said licenses issued for the use and sale of such drugs were not based on adequate data. A bench of Chief Justice D K Upadhyaya and Justice Tushar Rao Gedela asked the petitioner to give a representation to the DGCI, which was asked to decide the matter within three months. New Delhi, Jul 2 (PTI) The Delhi High Court on Wednesday asked the Drug Controller General of India to consult experts and relevant stakeholders in deciding a plea over drug combinations sold in the market for weight loss treatment. In an apparent reference to the recent death of popular TV actor Shefali Jariwala, the court said, 'See what happened two-three days back…' News reports suggest Jariwala was taking anti-ageing treatment for the last several years. The petitioner claimed the licenses have been issued without conducting any specific trials and studies and without noting the serious adverse health effects of the drugs. 'These drugs were originally developed and internationally approved for the treatment of Type 2 Diabetes Mellitus, with their primary therapeutic role being the regulation of glycemic levels. However, over the past few years, they have been repurposed and approved often through accelerated pathways for obesity treatment and chronic weight management, based largely on short-term efficacy trials,' the plea said. It said under the Drugs and Cosmetics Act, it is the DCGI which is the competent and statutory authority entrusted with taking appropriate measures to ensure safe use of drugs. The petitioner said representations were made on April 18 to the Centre and DCGI on the issue. The court, however, said the plea's concerns have to be first looked into and addressed by the DCGI as it allowed the petitioner to move the authority by way of an additional representation and bring relevant material and documents to its notice. The additional representation was directed to be submitted to the DGCI within a fortnight. 'In case such an additional representation is preferred enclosing all the documents and material necessary for addressing the issue raised in the writ petition, the same shall be attended to and considered appropriately and as per law by the authority concerned,' the court said. The order added, 'DCGI shall consult experts as also other stakeholders such as manufacturers of the drugs in question.' PTI SKV SKV AMK AMK This report is auto-generated from PTI news service.

India becoming self-reliant in defence capabilities: Ex-DRDO chief
'Now, the trend has reversed and we produce 70 per cent of our needs indigenously,' Saraswat, a former chief of the Defence Research and Development Organisation (DRDO), said. Addressing a press conference, Saraswat, who was in the steel city to participate in the fifth platinum jubilee lecture of CSIR-National Metallurgical Laboratory here, said India used to import 70 per cent of its defence requirements. Jamshedpur (Jharkhand), Jul 2 (PTI) NITI Aayog member and former DRDO chief V K Saraswat on Wednesday said India has been becoming self-reliant in its defence capabilities in the last 11 years of the Modi government. Barring a few equipment such as S-400 air defence system, a majority of the weapons and missiles — such as Akash and Brahmos — used during Operation Sindoor were manufactured in the country, he said. 'Today, the country is dependent on arms imports only for immediate requirements of the armed forces or where we do not have the technology,' he said. He said the country's self-reliance in defence capabilities has grown substantially in the last 11 years as the Centre promotes private sector participation. Saraswat said he was impressed with the work done in various fields by CSIR-NML scientists. The government has made provision of Rs 1 lakh crore to promote research and development in the private sector, he added. PTI BS ACD This report is auto-generated from PTI news service.

Ambedkar University Delhi, University of Ladakh bag Rs 65 lakh grant to preserve folk traditions
Titled 'Preservation, promotion and documentation of folk traditions: A study of Ladakh,' the initiative is focussed on integrating regional heritage studies with cutting-edge research. The three-year interdisciplinary project, commencing in July 2025, aims to bridge heritage, culture and technology by documenting Ladakhi folk practices through academic collaboration, an official AUD statement said. New Delhi, Jul 2 (PTI) Dr BR Ambedkar University Delhi (AUD) and the University of Ladakh have secured a Rs 65 lakh research grant from the Department of Science and Technology (DST), under the Science and Heritage Research Initiative (SHRI), to document and preserve Ladakh's rich folk traditions. 'This project will not only safeguard Ladakh's unique cultural heritage but also highlight the strength of academic partnerships,' said Prof Anu Singh Lather, vice chancellor of Ambedkar University. The joint effort stems from an MoU signed between the two institutions in September 2022. The project team comprises faculty from both universities, including Dr Sonam Jolden from the University of Ladakh and Prof Rukmini Sen and Dr Urfat Anjem Mir from AUD. University of Ladakh VC Prof Saket Kushwaha expressed optimism about the project's potential to deepen cultural understanding and create meaningful academic outputs.
