Innovations vital for zero-waste future
The one-day workshop was jointly organised by the Zero Waste Society of India (ZWSI), IISc campus, Oxford Institutions of Nagarabhavi and Ullal, BNMIT Friends of Nature Club, and the BNM Institute of Technology. Reflecting on his field experiences, Dr. Balagangadhar remarked that while manufacturers focus heavily on production, they often neglect waste disposal. 'Many industries still cite the lack of proper technology as an excuse. It's now up to the new generation to innovate and bridge this gap, supported by government initiatives and CSR funding,' he said.
He highlighted the importance of behavioural change and cited Indore's example as India's cleanest city — made possible through citizen participation and effective waste management systems.
ZWSI President Dr. B.R. Supreeth, who presided over the event, called India's large youth population its greatest asset. 'With Bengaluru as a startup hub, there is a growing demand for mentorship and research-driven innovation. ZWSI is committed to supporting multiple green startups in 2025,' he said.
ZWSI General Secretary Dr. Pratibha noted that awareness and grassroots engagement are key to the Society's mission. The event also featured student innovators and showcased technologies designed to reduce waste and promote environmental responsibility.

IISc researchers develop magnetically guided nanobots for tooth sensitivity relief
Researchers at the Indian Institute of Science (IISc), in collaboration with city based deep-tech startup Theranautilus, have engineered magnetic nanobots that can penetrate deep into dentinal tubules which are tiny tunnels in teeth that lead to nerve endings. The magnetic nanobots called CalBots can also form durable seals for worn enamel, offering lasting relief from sensitivity in one application. Bioceramic cement 'The CalBots use a completely new class of bioceramic cement. While bioceramics are widely used in orthopaedics and dentistry for their mineralising properties, the team wanted a solution tailored for hypersensitivity – a formulation that could travel deeper and last longer,' IISc said. Dental hypersensitivity affects nearly one in four people worldwide and occurs when microscopic tubules in the dentine—the layer beneath the enamel—is exposed due to erosion or gum recession. According to IISc these tiny tubules lead directly to nerve endings, which is why even a sip of cold water can cause a sudden, stabbing pain. Current solutions It added that most current solutions, such as desensitising toothpastes, offer only surface-level relief and need to be reapplied regularly. 'CalBots, however, are different. These 400 nanometre-sized magnetic particles, loaded with a proprietary calcium silicate-based bioceramic formula, are guided by an external magnetic field deep into the exposed tubules. They can reach depths of up to 300 to 500 micrometers inside the tubules. Once there, the bots self-assemble into stable, cement-like plugs that block the tubules and recreate a durable seal that mimics the natural environment of the tooth,' IISc said. The research team used human teeth extracted for clinical reasons and created conditions where the dentine was exposed. On these samples, they applied CalBots under a magnetic field for 20 minutes, during which the bots sealed the dentinal tubules by forming deep, stable plugs – a result confirmed through high-resolution imaging. Animal trials The team also progressed to animal trials in collaboration with researchers at IISc's Center for Neuroscience. 'It involved giving mice a choice between cold and room temperature water. Healthy mice preferred both equally. But the mice with induced tooth sensitivity avoided the cold water completely,' IISc said. 'After we treated the sensitive mice with our CalBot solution, they started drinking cold water again – the treatment worked like a charm. We saw 100% behavioural recovery. That was a big moment for us,' said Shanmukh Peddi, first author of the study and post-doctoral researcher at the Centre for Nano Science and Engineering (CeNSE), IISc, and co-founder of Theranautilus.

IISc researchers develop new imaging method to detect tumours
BENGALURU: Researchers at the Indian Institute of Science (IISc) in Bengaluru have developed a new imaging molecule that could help detect tumours accurately, at a fraction of the cost of current methods and without the risks associated with repeated radiation exposure. The molecule, called GPc, is created by scientists from the Department of Bioengineering at IISc and designed for use with Photoacoustic (PA) Tomography, a relatively new imaging technique. Their work could open the door to safer and more affordable tumour detection, especially for tumours located close to the body's surface. Tumour cells are far more active than healthy ones and consume a lot more glucose. PET (Positron Emission Tomography) scans — currently the gold standard in cancer imaging — take advantage of this by injecting patients with a radioactive sugar molecule called 18F-FDG. This sugar builds up in tumours, helping doctors spot them. But PET scans are expensive and repeated scans can expose patients to harmful radiation over time. Photoacoustic Tomography uses a safer approach. A near-infrared laser beam is directed at special light-absorbing molecules, called chromophores, which slightly expand and create tiny pressure waves when heated. These waves can be detected as sound signals and processed into 3D images. The method is less costly than PET or MRI and works well for mapping superficial tumours. At present, clinical PA imaging mostly relies on natural chromophores already found in the body, such as haemoglobin. But haemoglobin's signals, while useful, are not strong enough for certain diagnostic needs. This is where IISc's innovation comes in. The team conducted several experiments to see whether GPc enters cells the same way glucose does and whether it competes with glucose for entry. This was important because if GPc behaved like a glucose 'agonist', entering cells and being metabolised, it might not work as a good imaging agent. The results were promising. GPc entered tumour cells easily, was not metabolised, and did not depend on GLUT1 transporters (the proteins that normally carry glucose into cells).

Manekshaw Centres: IIT-Guwahati leads defence-academia collaboration
The director of the institute Prof Devendra Jalihal, said IITs, IISc, IIITs, and NITs would be the members of the Manekshaw Centres. "The Manekshaw Centres will periodically carry out dialogues with defence agencies and participate actively to define and design systems for Indian security needs. They will work towards finding Indian solutions, thus fulfilling the aspiration of Atmanirbhar Bharat," Jalihal said. "Aligning with Government of India's Atmanirbhar Bharat mission, this visionary initiative will unite IITs, IISc, IIITs, and NITs on a collaborative academic and research platform focused on defence technology and national security," the IIT-Guwahati statement said. The idea of setting up the nodal centres for collaboration among IITs was conceived by Lt. Gen. Dr. Subrata Saha (Retd.), and Prof. Sukumar Nandi, Dean of Administration, IIT-Guwahati. The Manekshaw Centres currently covers several IITs, IISc Bangalore and IIIT Delhi with more institutions expected to join soon.
