Hydrophone tested for Samudrayaan
The system, which works on acoustic sound waves, will enable real-time communication between researchers several kilometres deep in the ocean and those aboard the mothership.
The submersible will undergo integrated testing in early 2026 as part of the Samudrayaan mission under the Deep Ocean Mission.
In the Idukki test, hydrophones were suspended five metres below the surface from two separate boats stationed 5.5 km apart.
One boat remained stationary, while the other moved away. Hydrophones were also tested at varying depths as researchers on board communicated through the acoustic transmitter and receiver. The location was chosen for its long, straight stretch, reservoir and logistical support from the Naval Physical and Oceanographic Laboratory (NPOL), which provided boats and assistance.
The underwater telephone was initially developed and tested in laboratory conditions at NIOT.

"We are able to flawlessly communicate and hear between the boats," said NIOT director Balaji Ramakrishnan, confirming the clarity achieved over long horizontal distances. "We wanted to understand the device's maximum range by testing in a controlled environment like Idukki dam. The next step will be to test in actual ocean conditions."
In the open sea, the system will be tested for vertical range at depths of 1,000m-2,000m, where changing temperature, conductivity, salinity, and pressure may affect sound wave propagation.
Other critical subsystems are also undergoing independent testing. An underwater positioning system and a side-scan sonar were tested at Idukki. Life support systems were tested and optimised to reduce space inside the titanium spherical hull where researchers will be seated, leaving more room for scientific payloads.
NIOT researchers are also in discussions with Norwegian certification agency Det Norske Veritas, whose team, including members from Norway, Germany, and India, is in the city to evaluate Matsya 6000's components and safety standards.

TCS to lay off 12,000 as automation takes over: What future tech professionals must know about India's changing IT landscape
Tata Consultancy Services has announced plans to cut almost 12,000 jobs, that is about 2% of their total workforce. With a current employee base of over 600,000 worldwide as of June 2025, this is a significant move for a company that has long been the pillar of India's IT sector. According to media reports, the organisation is planning to spread these cuts across the financial year 2026 (FY26), and they're calling it part of their plan to get ready for the future. However, for an industry that employs millions of Indians and transformed cities like Bangalore and Hyderabad into tech hubs, this decision raises uncomfortable questions about what that future actually looks like. Everyone wants to be future-ready for drastic technology shift TCS wants to become what they call a "future-ready" organisation through skilling and redeployment for its employees. TCS CEO and MD K Krithivasan has also claimed that the lay off is strictly due to strict mismatch and shortage of employment opportunity. Additionally, they're also betting big money into artificial intelligence (AI), automation, and better infrastructure. The company reckons this means fewer people are needed for doing the same work, especially in middle and senior management roles. It's not just TCS taking this road. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Salma Hayek, 58,Shows Her Huge Size In New Photos Boite A Scoop Undo Across the IT industry, companies are using machines and smart software to replace humans. The repetitive, monotonous stuff that took up so much time before can be done by computers now. TCS management believes this will save them money and let them focus on the more complicated work that actually adds value for their clients. Money troubles and global uncertainty It's not just technological advancements that are prompting these job cuts. The global economic slowdown, coupled with rising geopolitical tensions and market uncertainty, has made businesses more cautious about their IT spending. TCS, which posted Rs 63,437 crore in revenue for Q1 FY25, a modest growth of 1.3% compared to the previous year, has been facing the effects of these macroeconomic challenges. While the company still recorded a 6% rise in net profits to Rs 12,760 crore, it also reported a 3.1% decline in revenue in constant currency, signaling a slowdown in demand for its services. Amid these pressures, TCS has tightened internal policies to enhance productivity. For instance, employees are now required to log a minimum of 225 billable days each year, and bench time (the period when employees are between projects) has been capped at just 35 days. These policies, designed to increase operational efficiency, signal a growing drive to maximize return on human capital, efforts that contribute to the company's ongoing restructuring. What's being offered to the laid off employees? TCS is providing a range of support to employees impacted by the layoffs: Reskilling & redeployment : Opportunities for affected employees to transition into new roles within the company through training. Financial benefits : Severance packages and extended insurance coverage. Outplacement support : Job search assistance and career counselling to help employees find new opportunities. Counselling services : Professional counselling to support emotional well-being during the transition. Gradual transition : Layoffs will be spread over the course of FY26, giving employees ample time to prepare. TCS's approach aims to ensure a compassionate, supportive transition for those affected. TCS might've started a domino trail Other IT companies can be expected to be watching TCS closely right now. When the biggest organisation in the market takes a step like this, it usually means others will follow. This push towards automation, and cutting costs isn't something only TCS is doing. India's wider tech scene has been going through this for some time already. Startups and smaller companies like Byju's and Ola Electric have been cutting jobs as they try to become profitable and reduce their costs. IT workers should brave themself for a whole new world These job cuts are happening just as the whole Indian IT industry is trying to figure out what kind of workers it needs going forward. When AI becomes a bigger part of how businesses work, the skills that employees need change completely. TCS says they're trying to help their workers learn new skills and move into different roles instead of just getting rid of them. They want to make sure they can still deliver good service to their clients while helping their employees adapt to this new world of work. This is going to affect the whole sector. As companies rely more on automation, AI to make things run smoothly, they probably won't need as many people in traditional jobs, especially in middle management. But they might need more highly skilled professionals who know how to work with AI and other new technologies. The move is not exclusive for TCS, similar restructuring efforts can be expected across IT sector in India. Ready to navigate global policies? Secure your overseas future. Get expert guidance now!

You won't believe this overlooked cause can be behind heart failure; new study unveils shocking results
A new study has discovered that hearing impairment often results in an increased risk of heart failure in human beings. According to the study, psychological distress caused by hearing impairment plays a 'notable' role in developing problems with the heart. Experts in China analyzed data from the UK Biobank, studying 164,431 people who took hearing tests designed to determine hearing ability for the research. Out of all participants, about 160,062 didn't use hearing aids . Heart failure happens when the heart cannot pump blood effectively, leading to symptoms like fatigue, shortness of breath, and swelling in the legs and ankles. According to the Independent, test participants were split into three groups based on how they performed in a digit triplet test (DTT), which checks for hearing issues by using random digit combinations against the background noise.

'Compared with those with normal hearing, participants with insufficient hearing, poor hearing, or hearing aid use had higher heart failure risks,' researchers were quoted by The Independent as saying. Live Events Among people who didn't use hearing aids, high SRT levels were also linked to psychological distress, social isolation, and neuroticism. 'We have been the first to demonstrate that poor hearing ability is significantly associated with a higher risk of incident heart failure in the general population,' the researchers further stated. 'Psychological factors, especially psychological distress, play a significant mediating role in this association. If further confirmed, hearing impairment may be a potential risk factor or marker for incident heart failure in the general population, highlighting the importance of integrating hearing health assessments into broader cardiovascular risk evaluation frameworks. Moreover, strengthening psychological intervention in people with hearing impairment may be an important path and strategy to reduce the risk of heart failure,' they continued.
