Mobile device to make TB screening simpler
Guwahati: Researchers at Tezpur University have developed a cost-effective and mobile device for detecting Tuberculosis (TB) cases using a smartphone. The innovative diagnostic equipment, designed by a team led by Prof. Pabitra Nath from the physics department, was specifically engineered to serve communities in rural and isolated regions where sophisticated healthcare infrastructure is limited. A TU spokesperson said the new device stands out as it does not need any chemicals or dyes for TB detection like in conventional techniques, but uses the natural glow (autofluorescence) of TB bacteria for detection of the disease. "The device has a built-in heating system to improve test accuracy and can be operated using a smartphone," he said. Its affordability at under Rs 25,000 and lightweight design of less than 300 grams makes it highly portable. These characteristics make it particularly suitable for regions with basic healthcare facilities. "While LED-FM offers higher sensitivity than conventional optical microscopy, it has several drawbacks. It depends on costly equipment, chemical staining agents like auramine-O, and trained personnel for sample preparation and interpretation," Prof. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Many Retirees Unaware Of No Deposit Car Insurance Based On Their Age OTTO Insurance Learn More Undo Nath said. "The device developed by the TU researchers leverages the principle of autofluorescence. The team's key innovation lies in the integration of a heating element within the sensor system. By raising the temperature of the bacterial sample, the system enhances the natural fluorescence signal from mTB cells, enabling trace-level detection without the use of stains or dyes," he research group comprises two scholars, Biprav Chetry and Chunuranjan Dutta, from the Physics Department, alongside JP Saikia and Santanu Goswami from the Molecular Biology and Biotechnology Department, and Abhijit Gogoi representing Labdig Innovations and Systems Pvt. Ltd. The team already filed a patent for the device (Indian Patent Application No. 202431035472), and their findings were published in the international journal Biosensors and Bioelectronics. The University's Vice Chancellor, Prof. Shambhu Nath Singh, offered his congratulations and noted that this development could significantly advance TB detection efforts, particularly in rural communities.

Tezpur University team develops low-cost device to detect tuberculosis
GUWAHATI A team of researchers from central Assam's Tezpur University has developed an affordable and portable device to detect tuberculosis (TB). The researchers said the device, using the autofluorescence or natural glow of the TB bacteria for detection instead of any chemical or dye, has been specially designed for use in rural and remote areas where advanced medical facilities are not easily available. Pabitra Nath of the university's Department of Physics and the team leader, said the device has a built-in heating system to improve test accuracy and can be operated using a smartphone. 'It costs under ₹25,000 and weighs less than 300 grams, making it a perfect fit for places with limited healthcare infrastructure,' he said. The other members of the team are Biprav Chetry and Chunuranjan Dutta, research scholars from Tezpur University's Department of Physics; J.P. Saikia and Santanu Goswami from the Department of Molecular Biology and Biotechnology; and Abhijit Gogoi from Labdig Innovations and Systems Private Limited. Early and accurate diagnosis is crucial in stopping the spread of TB, a major public health issue in India. The World Health Organization (WHO) and India's National TB Elimination Programme currently recommend LED fluorescence microscopy as the gold standard for TB screening. However, the standard testing method recommended by the WHO needs expensive machines and trained technicians, which are not available in many rural areas. The new device can solve this problem by making TB testing simpler and more accessible, the researchers said. 'While LED-FM offers higher sensitivity than conventional optical microscopy, it has several drawbacks. It depends on costly equipment, chemical staining agents like auramine-O, and trained personnel for sample preparation and interpretation. Furthermore, its reliance on laboratory infrastructure makes it impractical in many rural settings,' Professor Nath said. The device developed by the Tezpur University researchers leverages the principle of autofluorescence, a natural property of certain microbial cells, including Mycobacterium tuberculosis (mTB) cells, that emit a fluorescence signal when excited by a specific wavelength of light. 'The team's key innovation lies in the integration of a heating element within the sensor system. By raising the temperature of the bacterial sample, the system enhances the natural fluorescence signal from mTB cells, enabling trace-level detection without the use of stains or dyes,' Prof. Nath explained. The team has filed a patent for the device, and their study was published in Biosensors and Bioelectronics, an international journal.

Toddlers in India are missing key developmental milestones due to excessive screen time; parents, mental health experts weigh in
In many homes across northern India, toddlers are spending significantly more time in front of screens than experts recommend, often with parents unaware of the developmental risks. A new study published in BMJ Paediatrics Open, based on a survey of 3,624 parents across five Indian states, found that screen exposure among children aged two–five far exceeds the World Health Organization (WHO) guidelines. 'Parents used screen time for their own rest, to carry out household chores, or to pacify their children,' the study noted. Many believed this was beneficial, but the trade-off was clear: reduced verbal interaction, physical activity, and developmental play. Speech and hearing specialist Priyank Bhutani, a co-author of the study and PhD scholar at Tezpur University, said the research was driven by a lack of Indian data on how screen time affects early development. 'About 13 per cent of children were getting up to eight hours of screen time daily, and 70–80 per cent of parents didn't even know what the guidelines were,' he told This stands in stark contrast to World Health Organization guidelines, which recommend zero screen time for children under 2, and no more than one hour of supervised, high-quality content for ages 2–5. Instead, activities like reading or storytelling with a caregiver are encouraged. 'Screens were being used to feed, soothe, and occupy kids,' Bhutani said. 'Children with higher screen time were found to engage less in talking with parents and peers, had reduced outdoor play and were less likely to participate in creative activities,' the study mentioned. Bhutani describes screens as 'digital helpers' that became indispensable during and after the COVID-19 pandemic. 'They became the easiest way to keep children occupied while parents focused on daily responsibilities.' This resonates with many urban parents. Natasha Puri, a mother of two toddlers aged two and four, admitted, 'With two young kids, a job, and trying to protect my mental health, screen time is a crutch. We're way over the 20-minute recommendation, but it's the best I can manage.' Similarly, Ratish Sreekumar, 41, father to two children aged two and five, said: 'It started with the intention of augmented learning, but yes, I'd be lying if I said entertainment, convenience and simply keeping him occupied didn't play a role.' What makes this trend particularly concerning is how screens are infiltrating critical learning moments. The damage isn't just about time spent on screens, it's about what that time is replacing. 'When a child eats while staring at a screen, they're not experiencing the food –– how it smells, tastes, feels,' Bhutani said. 'Gone is the baby talk: 'Open your mouth, it's yum!' There's no interaction.' This loss of communication is being seen in clinics. 'As a speech and language therapist, I've seen a surge in parents reporting delays in speech and language,' Bhutani said. The underlying issue, he explained, is fundamental: 'Language is a learned behaviour. It doesn't happen automatically. A screen cannot give you two-way communication. You need a social environment to learn.' Mental health professionals are observing similar patterns. Dr Sakshi Mehrotra, an existential humanistic therapist and founder of Mindlogs, noted a rise in toddlers with 'delayed speech, reduced eye contact, poor frustration tolerance, and difficulties engaging in imaginative play or independent exploration, all foundational to healthy emotional and cognitive development.' 'Often, these signs get misread —– parents might assume the child is just shy or independent,' she said. 'Reduced curiosity or playfulness – the child preferring passive screen time over exploring toys, nature, or social spaces – difficulty tolerating boredom, meltdowns when the screen is turned off, inability to self-soothe without digital distraction are all red flags.' Counselling psychologist Rajvi Turakhia describes this as 'digital dysregulation.' Children exposed to fast-paced screen content become desensitised to normal stimuli. 'The brain begins craving the dopamine hit of quick cuts, loud sounds, and instant gratification. Once the screen's off, regular life feels boring or even frustrating.' Many parents are aware of the risks but feel stuck. Neha Popli Dhamija, a teacher and mother of a 4-year-old, said, 'My daughter started mimicking cartoon characters and behaving like them. That's when I cut back and focused on play instead. It made a big difference in her mood and attention span.' She also said, 'In hindsight, too much screen time hindered development, not just for my daughter but many kids around. I've seen cases where children face speech delays or show signs of autism linked to excessive screen exposure.' Abhilasha Daga, mother of a 3-year-old, said, 'On high screen time days, he's more irritable, less responsive, and harder to settle at bedtime. It's like he's overstimulated.' For Sreekumar, the effects were behavioural. 'My 2-year-old becomes more stubborn and unruly after screen time, so we've started capping it and being more selective about the content.' The study found that what children watch is just as important as how long they watch. The WHO guidelines specify that even the permitted hour for two-five year olds should be 'assisted'. Bhutani stressed that screen time must be interactive and supervised. 'It should be co-viewed, not passive,' he said. 'We must pay attention to both duration and content.' Puri noted changes in her son's behaviour depending on what he was watching. 'He was more aggressive when watching angry dinosaurs. I had to ban that content.' Despite widespread awareness that excessive screen time isn't ideal, parents consistently report a lack of practical, accessible guidance. 'I don't think there's enough clear or accessible guidance for Indian parents. Most information is either too technical or hidden behind paywalls/paid subscribers. There's also a lot of conflicting advice online,' said Abhilasha. This echoes the research findings. 'There's a huge gap,' Bhutani said, adding, 'There should be an Indian-based, Indian context on Indian data guidelines. And there should be programmes to train parents what to do if you're not giving a screen.' Turakhia said, 'There's a serious lack of accessible, non-judgemental psychoeducation for parents. Many don't have the information they need to make informed choices or aren't sure what realistic alternatives look like.' Mental health professionals stressed that addressing this issue requires understanding, not condemnation. 'Parents are doing their best with limited tools,' said Dr Mehrotra. 'Many believe that educational apps compensate for real-life interaction, but they don't.' Turakhia points out that modern parenting is uniquely challenging. 'Dual-income homes, limited support, and digital distractions have reshaped the parenting landscape. Rather than strict prohibitions, we need small, sustainable shifts –– like screen-free meals, bedtime routines, or co-viewing on weekends.' The good news is that it's not too late. 'Children's brains are incredibly plastic in the early years,' Turakhia explained. 'Even small changes can yield significant improvements –– if parents have the right tools.' Bhutani emphasises the bigger picture. 'If this continues unchecked, screen exposure could become a public health crisis. We need awareness campaigns, government-led initiatives, and most importantly, support for parents who want to do better but don't know how.' He also said, 'Most parents know there's a problem. They're not in denial, they just need help navigating it.' As India continues its digital transformation, the goal, experts agreed, is to help families make informed choices. The challenge isn't to eliminate screens entirely but to find a sustainable balance. 'It's about slowly reclaiming space for shared, screen-free moments that nurture both parent and child,' Dr Mehrotra said. Swarupa is a Senior Sub Editor for the lifestyle desk at The Indian Express.

Tripura Univ moves up to 44 in IIRF '25, but remains NE's lowest-ranked central varsity
Agartala: Tripura University has improved its position in the Indian Institutional Ranking Framework (IIRF) 2025, ranking 44th in the list of 50 top central universities of the country. Tired of too many ads? go ad free now The position of Tripura University was 47th last year and 28th in 2023. However, the rank of Tripura University was found lowest among the 10 central universities in the northeast this year too. Rajiv Gandhi University in Itanagar became best in the region securing 13th rank in IIRF this year, followed by Tezpur University (24th), Mizoram University (25th), Central Agricultural University (26th), Northeastern Hill University, Shillong (29th), Nagaland University (34th), Sikkim University (36th), Assam University (37th), and Manipur University (40th). The deterioration of Tripura University began with the appointment of incumbent vice-chancellor Prof Ganga Prasad Prasain in Aug 2020. He has been accused of large-scale corruption in the appointment of faculty and non-teaching staff, including his son as an assistant engineer. Allegedly, the academic ambiance in the university has gone down, rather, it has become a hub of political activities of saffron outfits. The ministry of education has been flooded with complaints against the vice-chancellor that reportedly affected the IIRF ranking. According to IIRF data, Tripura University achieved an overall index score of 901, an increase from 897.86 in 2024, but a fall from 929.99 in 2023.
