NATIONAL: SCIENCE & HEALTH : VACCINES: Chhattisgarh scientists develop new biomarkers to predict Covid severity

The new biomarkers have been designed to diagnose early stages of infection in patients who are affected with severe COVID-19 illness.

In a major breakthrough, the scietist of the Multi-Disciplinary Research Unit (MRU) in Dr Bhimrao Ambedkar hospital, Raipur, have introduced the country’s first-ever bio marker kit that could provide early-stage severity assessment of Covid.

The research, published in Scientific Reports, a journal by the Nature Publishing Group, holds promise for enhancing patient care during the pandemic. The new biomarkers have been designed to diagnose early stages of infection in patients who are affected with severe COVID-19 illness. With the help of an invented kit, doctors will be able to decide whether it is necessary to hospitalise the patient or he can recover at home through medicines.

Under the headship of Dr Jagannath Pal, the team utilising leftover samples from routine Covid-19 tests, has developed a method with impressive accuracy-boasting a sensitivity of 91 per cent and a specificity of 94 per cent in non-comorbid.

The MRU’s research also aligns with the Prime Minister’s “Make in India” initiative. The project was supported by the health administration of Chhattisgarh and funded by the Department of Health Research (DHR), Government of India.

How the kit works

The test results determine the response of adaptive immunity to new virus infection. The test required input of leftover RNA followed by the routine COVID-19 diagnosis by RT-PCR. Complementary DNA is prepared from RNA samples by reverse transcription.

The complementary DNA is used for subsequent qPCR reactions to determine the expression of the signature genes. By analyzing the level of the genes we determine a “Severity Score”. If the score is lower than a cut-off value it indicates the good immune response (T-cell) suggesting low risk and the patient could recover without the requirement of advanced medical facility or extra drug treatments. If the score is higher than a cut-off value it indicates a poor immune response (T-cell) suggesting high risk and patients may require advanced medical facility or extra drug treatments for recovery. The same test could be used for other virus infection also.

NATIONAL: DRONE PATENTS: Patent Granted: Path-Breaking Drone Technology Developed by Anna University Researchers to Revolutionise Package Delivery Applications

A path-breaking technology has been developed by the researchers at the Madras Institute of Technology, Anna University, Chennai that may open up a new era of drone operations.

The airborne-based intelligent autonomous landing system for mini-Unmanned Aerial Vehicles that come with accurate identification of geographical location of landing sites from the plurality of images captured has been granted patent by the Indian Patent Office, Intellectual Property India.

“The technology would immensely help in the delivery/pick up of load such as weapons, ammunition, medicines, food etc. to armed forces deployed along hilly terrains or inaccessible locations along the border,” said Dr K. Senthil Kumar, Professor and Director, Dr Kalam Advanced UAV Research Centre, Department of Aerospace Engineering, MIT,

The system developed by his team of researchers is capable of not only finding the precise location of a marker like a particular coloured dress or object on the site and land there safely even if it were to be a hilly terrain with uneven surface and slope. At present, existing UAVs were designed to land at a pre-determined well prepared plain surface locations,

Dr Senthil Kumar explained, “Once the landing site is identified, the position coordinates are obtained and UAV lands at the target including moving platforms. Further, QR code can also be used to enhance reliability. The efficiency of the UAV landing system is increased, landing time is reduced, and the complete process is on-board and autonomous using AI and deep learning algorithms. The system is particularly useful for Beyond Visual Line of Sight (BVLOS) applications.”

According to Dr Senthil Kumar, the UAV landing system could be utilised in high-altitude logistics drones to assist armed and border security forces in day-to-day essential supplies delivery to border posts, emergency relief and rescue operations or delivery of certain goods to strengthen combat missions.

“We now have UAVs with the capability to fly up to 50 kg load to 20 km. Efforts are on to enhance the load to 100 kg and flying distance to 50 km,” he added.

Highlighting the UAVs utility, Dr Senthil Kumar said, besides defence, firefighting and surveillance operations, the intelligent autonomous landing system for mini-Unmanned Aerial Vehicles could also be used for civilian missions such as organ/medicine delivery in healthcare, product delivery in e-commerce etc.

“The invention marked a significant breakthrough in drone technology as it would revolutionise the package delivery applications. The existing delivery methods were done only by way of airdrop from certain altitudes,” he remarked.

NATIONAL: SCIENCE & TECHNOLOGY RESEARCH: Single-Molecule Transistor Breakthrough in Nanoelectronics

In a major achievements for nanoelectronics , researchers at the S. N. Bose National Centre for Basic Sciences have developed a pioneering transistor design that utilises single molecules controlled by mechanical forces.

This innovative approach marks a significant departure from conventional electronic technologies, promising advances in ultra-compact electronics, quantum information processing, and advanced sensing applications.

The breakthrough centres on a technique known as the mechanically controllable break junction (MCBJ). This method diverges from traditional transistors by using mechanical forces to regulate electronic properties instead of electrical signals. To achieve this, the researchers employed a piezoelectric stack to precisely fracture a macroscopic metal wire, creating a nanometer-scale gap tailored for the insertion of single molecules, such as ferrocene.

Ferrocene, a molecule consisting of an iron atom sandwiched between two cyclopentadienyl rings, displays unique electrical behaviours when subjected to mechanical manipulation. This phenomenon occurs because the mechanical gating process alters the molecular structure, influencing how electrons are transported through the junction.

By exploiting this characteristic, the researchers have demonstrated how mechanical forces can control electronic behaviour at the molecular level, opening new avenues for advanced electronic devices.

Dr Atindra Nath Pal and Biswajit Pabi, leading the research team, found that the orientation of ferrocene molecules between silver electrodes plays a critical role in the transistor’s performance. Their experiments revealed that the device’s electrical conductivity could either be enhanced or diminished based on the specific alignment of the molecules. This discovery highlights the crucial impact of molecular geometry on electronic properties and device functionality.

In further studies, the researchers investigated the use of gold electrodes in combination with ferrocene at room temperature. The results were remarkable: the transistor exhibited a low resistance of approximately 12.9 kΩ, which is about five times the quantum of resistance.

This is notably lower than the typical resistance found in molecular junctions, which averages around 1 MΩ. Such low resistance suggests the potential for developing highly efficient, low-power molecular devices that could revolutionise several technology sectors.

The implications of this breakthrough extend beyond traditional electronics. The ability to precisely control electron transport through single molecules could lead to the development of ultra-compact devices with applications in quantum computing, where managing electron flow with high precision is crucial.

Additionally, the advancements in sensing technology could benefit from the enhanced sensitivity and specificity provided by these molecular-scale devices.

This innovative approach also aligns with broader trends in the technology sector, where there is a growing focus on miniaturisation and energy efficiency. By harnessing mechanical forces to control electronic behaviour, researchers are pushing the boundaries of what is possible in nanoelectronics and paving the way for next-generation technologies that could reshape the digital landscape.

India is making significant headway in the field of Nanotechnology , with groundbreaking advancements in sensor technology and material science that promise to enhance healthcare, food safety, and environmental monitoring.

Recent advances in nanotechnology have led to highly sensitive sensors using Metal-Organic Frameworks (MOFs) and 2D materials. These low-cost, point-of-care devices quickly detect health conditions, food safety parameters, and environmental pollutants.

Researchers from the Institute of Nano Science and Technology (INST) have developed sensors that excel in accuracy and reliability, addressing critical needs in health, food safety, and environmental monitoring.

This achievement by researchers at the S. N. Bose National Centre for Basic Sciences represents a significant leap forward in the field of nanoelectronics. By integrating single molecules into transistor designs and controlling their properties through mechanical forces, the research team has set new standards for electronic devices.

As this technology evolves, it holds the promise of advancing multiple fields, including quantum information processing, ultra-compact electronics, and advanced sensing applications, heralding a new era of technological innovation.

INTERNATIONAL: SCIENCE – RESEARCH & DISCOVERY: Living walls: Indian student Prantar Tamuli develops carbon capturing building material in University College London(UCL)

Tamuli developed the C-ELM under the guidance of research supervisors during his MSc in Bio-Integrated Design, even innovating new methods to culture cyanobacteria at home during the Covid-19 lockdown in London.

An Indian student at University College London (UCL) has developed an innovative construction biomaterial that utilises living microorganisms to remove carbon dioxide from the atmosphere, potentially revolutionising the building industry’s carbon footprint.

Prantar Tamuli, a Master’s student in UCL’s Biochemical Engineering Department, recently introduced this material as part of an art installation at St Andrews Botanic Garden in Scotland.

The biomaterial, known as a cyanobacterial engineered living material (C-ELM), incorporates living cyanobacteria within translucent panels that can be mounted on the interior walls of buildings. As the microorganisms grow through photosynthesis, they capture carbon dioxide from the air.

“My goal with developing C-ELM is to shift the construction of our future human habitats from being a significant carbon-emitting activity to one that actively sequesters carbon,” Tamuli was quoted as saying by news agency PTI.

Through a process called biomineralisation, the captured CO2 is converted into calcium carbonate, effectively trapping the carbon.

A kilogram of C-ELM can capture up to 350g of carbon dioxide, while the same amount of traditional concrete would emit approximately 500g of CO2. A wall covered with 150 square metres of these panels could sequester about one tonne of carbon dioxide.

“The potential of this biomaterial is immense. If scaled up and widely implemented, it could significantly reduce the construction industry’s carbon footprint,” said Professor Marcos Cruz of UCL’s Bartlett School of Architecture and co-director of the Bio-Integrated Design Programme, according to the report by PTI.

Tamuli developed the C-ELM under the guidance of research supervisors during his MSc in Bio-Integrated Design, even innovating new methods to culture cyanobacteria at home during the Covid-19 lockdown in London.

Dr Brenda Parker, co-director of the Bio-Integrated Design Programme, added, “By breaking down traditional disciplinary barriers, we can enable breakthroughs like these. Biotechnology is now in a position to transform sustainable design and construction,” PTI reported.

Inspired by studying stromatolites—ancient structures formed by algal mats—Tamuli focused on the cyanobacteria species *Kamptonema animale*, which grows in long strands that easily bind to surrounding materials within the panels. The calcium carbonate produced by the cyanobacteria strengthens and reinforces the panels.

These panels offer multiple benefits for buildings, including being lightweight, sound-absorbing, translucent enough to allow light to pass through, and thermally insulating to improve energy efficiency.

The first panels were publicly displayed inside the “Bioscope” pavilion at St Andrews Botanic Garden, showcasing low-carbon, nature-inspired construction methods designed by the collective Studio Biocene. A patent for C-ELM technology has been filed by UCL’s commercialisation company, UCL Business.

INTERNATIONAL: SCIENCE & TECHNOLOGY: Indian American Deblina Sarkar. The girl who flew away on the wings of her mind. Boss of the Nano-Cybernetic Biotrek research lab at MIT, Boston, and harvester of a dozen awards in the past year alone

Boss of the Nano-Cybernetic Biotrek research lab at MIT, Boston, and harvester of a dozen awards in the past year alone. And yet, bet you didn’t know that she comes inspired from a bereft corner of Bengal.

Deblina Sarkar is not keen to tell her story. She is not disinterested either. Over a Zoom call from Boston, US, she comes across as matter of fact, pleasant and rooted in her work — she cannot wait to be done with this interview and return to the lab.

The story of her journey from rural Bengal to Boston is full of silences — studied, not awkward — and shorn of specifics as if she has already measured the distance she wants to maintain between her story and audience.

But when she does talk, she doesn’t do platitudes. When I ask her what it is she wanted to do as a girl, she replies, “I wanted to create knowledge, add to the production of knowledge rather than just implement what already exists.” She says it simply, self-assuredly and in a non-self-important tone. If I slip into Bangla, she too replies in her mother tongue, but switches to English whenever she is discussing her work and the specifics of it.

And, yes, the only time she shows emotion and smiles a wide smile that rises to her eyes is when she talks about her parents, Barid Baran and Asima, and nephews Qubit and Quitron.

Barid Baran and Asima are far more animated when it comes to telling the story of Deblina’s journeying. Which is why, Deblina’s story is best told with them in the role of chief narrators.

“When she was only three, she threw a tantrum because she wanted to go to school,” says Barid Baran. Indulging her would mean quite the long commute. It meant walking two kilometres to the Nangi train station and then getting off at Tollygunge and walking some more to reach the school itself.

It was not very different from Barid Baran’s own story from his student days. In 1960s Bengal, there was no school in his village. So he trekked two miles on foot to go to the nearest school. He wanted to be a scientist, so when the time came to go to college he shifted to the nearest town with one.

Deblina was happy — no, delighted — to go to school. “I am lucky, my parents never treated me and my brother differently,” she tells me. As Asima tells it, if there was anything that made Deblina unhappy as a child, it was the teacher’s red pen. “She couldn’t bear to have anything in her notebook stricken off with a red pen.” Asima narrates a fond tale about the time Deblina was learning her English alphabet. Something about her mother saying “P” should be written in a certain way, and the little girl insisting her way was also correct.

In 1972, Barid Baran took the entrance test for the IITs and could not clear it. But the scientist in him continued to be, dabbling in inventions of his own. Deblina recalls watching her father build a washing machine that ran without electricity, a pulley that could lift heavy objects to the roof of the house.

Do dreams come coded with the DNA or does one contract them from close contact? Who can say? When she was in Class IX, Deblina started preparing for the Joint Entrance Examination. “Even the day before her Class X history exam, she was sitting with her physics texts,” says Asima. “I had to tell her, how will you go to IIT if you don’t pass your boards,” adds Barid Baran.

In 2004, Deblina joined what is today known as IIT Dhanbad. When news got around, the neighbours said, “Now she will be able to pay for her own dowry.” Deblina laughs at the memory. Thereafter, Deblina left for the US — a PhD in nanoelectronics at the University of California, Santa Barbara.

One might think it was a big leap, a big deal, and yet neither Deblina nor her parents make it sound that way. Instead they talk about how she comes home every year and behaves as if she never left, wears her old clothes, enjoys her mother’s maan kochu bata and machher jhol. And how they join her every time she has a conference in a new country — “She sends us tickets,” says Asima.

All three of them are more eloquent when it comes to holding forth on the nuts and bolts of life. Deblina talks about nanoelectronics like she is chatting about the weather. “Nanoelectronic devices consume a large amount of energy etc. etc.” So she started exploring other low-powered computational systems. She says, “If you think about it, the human brain is the most energy-efficient computational system.”

I am not sure if I am following the science talk, when she provides the answer herself. It was this line of inquiry that brought her to a territory she had vowed to never enter. Biology.

There were risks in making a transition this steep, but her mind was made up. To the question of what it feels like to be a woman in STEM, she just shrugs. “If I was ever discriminated against, I would not know,” is her answer.

What she and her team are doing today is this — trying to come up with a non-invasive, wireless nanoelectronic device that can coexist within the brain. They aim to treat diseases such as Alzheimer’s, Parkinson’s and even brain cancer using this method. She says with a smile and a nod, “We are hoping to start the clinical trial within the next two years.”

And yes, she is thinking of starting a scholarship for girl-students who need it back home to encourage them to be able to study science in high school.

NATIONAL: RESEARCH – SCIENCE & TECHNOLOGY: Indian Scientists Make Major Breakthrough In Quantum Cryptography

Quantum cryptography, also known as quantum encryption, refers to various cybersecurity methods for encrypting and transmitting secure data based on the naturally occurring and immutable laws of quantum mechanics.

In a major breakthrough, a team of Indian scientists has created a user-friendly way to generate unpredictable random numbers crucial for stronger quantum data encryption and provide robust cybersecurity, the Ministry of Science & Technology has said.

Quantum cryptography, also known as quantum encryption, refers to various cybersecurity methods for encrypting and transmitting secure data based on the naturally occurring and immutable laws of quantum mechanics.

The Raman Research Institute, Bengaluru, which is an autonomous institute of the Department of Science and Technology (DST), performed a photonic experiment to demonstrate a violation of what is called the Leggett Garg Inequalities (LGI) — a litmus test for “quantumness” in a system in a loophole-free manner.

The team carried out extensive research in collaboration with researchers from the Indian Institute of Science (IISc), Bengaluru, IISER-Thiruvananthapuram and the Bose Institute, Kolkata to use such LGI violation in a completely unexplored domain — truly unpredictable random number generation, secure against device tampering and imperfections.

These numbers are crucial in applications like cryptographic key generation, secure password creation and digital signatures, among others.

With further engineering interventions and innovations, devices adopting this method could find powerful applications not only in cybersecurity and data encryption but also in diverse areas like economic surveys and drug designing/testing.

“We have successfully generated random numbers using temporal correlations certified by the violation of the Leggett Garg Inequality (LGI),” said Professor Urbasi Sinha, faculty at the QuIC lab at Raman Research Institute, and the corresponding author of the paper published in the Physical Review Letters.

“Our experimental setup ensures a loophole-free violation of LGI, providing an additional advantage of generating loophole-free randomness,” Professor Sinha added.

According to the researchers, this new method offers the enhanced protection “we all need in our daily lives, by using truly random numbers to generate keys that will be used to encrypt the passwords”.

There are several advantages to generating certified random numbers using this method.

“These include the creation of strongly protected passwords, enhanced account security by resisting brute-force attacks, ensuring uniqueness, integrity thereby preventing forgery and token generation with multi-factor authentication, adding a crucial security layer in this vulnerable cyber world,” explained Dr Debashis Saha, IISER Thiruvananthapuram faculty and co-author of the study.

The experiment generated over 9,00,000 random bits at a rapid rate of nearly 4,000 bits/second.
