EDITORIAL

Science cannot be divided into what is up to date and what is merely of antiquarian interest; it is to be regarded as the product of a growth of thought- Peter B. Medawar As the year draws to a close, our last newsletter issue of 2015 brings to you the latest round up on news of our Fellowship schemes, updates on our Fellow’s research, public engagement and science communication activities along with some interesting interviews and outreach initiatives . Our Annual Report of the year 2014-15 can be viewed here.

On the Fellowships front, all our fellowship competitions are presently closed and the submitted applications for Early Career Fellowships and Senior and Intermediate Fellowships (basic scheme) are under review. Interview for Clinical and Public Health fellowships, Research Training Fellowships, Margdarshi Fellowships and Senior and Intermediate Fellowships (basic research scheme) were held in the first week of November in Hyderabad, results of which will be announced shortly. The 12th two-day Science Communication workshop held in Hyderabad on 14-15 September, was shortly followed by a one-day sciComm101 workshop at Vinayaka Missions University, Salem, Tamil Nadu on 21 September which was attended by around 80 PhD students and young researchers. As part of public engagement exercise, our Fellows sent wonderful entries for our first ‘Research Image Competition’, the results of which can be found in this issue.

In this issue, we feature recently published work of our Fellows, Drs Benu Brata Das, Rakesh K Laishram, Thomas Pucadyil, Vatsala Thirumalai & R Mahalakshmi. Recognising and echoing the importance of the ‘World Antibiotic Awareness Week’ that starts today, the feature article “Emergence of a new Resistance” describes the emerging crisis of Antimicrobial Resistance, one of the biggest threats to global health today. Our Intermediate Fellow at IGIB, New Delhi, Dr Sheetal Gandotra, shares with us the impact of her current research on Mycobacterium Tuberculosis, role of scientists and science in India and much more, in the ‘Fellow in the Spotlight’ section. Last but not the least, our Grants Adviser, Dr Ranjana Sarma reminisces about her early childhood and research days, recounts how India Alliance experience has been a mixed bag, her love for martial arts and dance, in the ‘IA Staff Corner’ section

SCIENCE COMMUNICATION WORKSHOPS From a SciComm participant to an IA Fellow Few of our current Fellows had attended the two-day SciComm Hyderabad workshop before they applied for the IA Fellowships which were eventually awarded to them. Three of them share their thoughts here on how the training helped them to write successful grant applications and their general experience of the workshop.

Dr Yogesh Dahiya, Early Career Fellow, IISER Mohali

SciComm Hyderabad 2011 The things that I expected, including a comprehensive overview of Early Career Fellowships, scientific presentation skills, went as expected. Most important aspect of the SciComm for me was the discussion session with the mentor. I was planning to change my research field from cellular immunology to the molecular biology of learning and memory. Based on my short research proposal (which eventually became my ECF proposal) I was grouped with students having somewhat overlapping research interests. The mentor we had during the SciComm workshop was an eminent neuroscientist from India.

It was the first time that I had any discussion on merits and shortcomings of my research proposal with the expert in the field. The discussions later proved to be extremely valuable.

Dr Giridhara R Babu, Intermediate Fellow, Public Health Foundation of India

SciComm Hyderabad 2013 The workshop has been a catalyst in honing my grantsmanship skills. It was a very well crafted workshop by the India alliance team. The sessions were engaging and focused. The session on the live recording of presentations proved to be very productive. Interacting with peer scientists was enjoyable; the richness of shared experiences was a great way to learn. Thanks to this opportunity, I was able to successfully apply the learning into accomplishing the award of intermediate fellowship. I highly recommend to any young public health researcher to attend this workshop for enhancing the skills in scientific communication.

Dr Tavpritesh Sethi, Early Career Fellow, AIIMS, New Delhi

SciComm Hyderabad 2014 I found the workshop to be extremely useful to improve grant applications. Since I was also applying for the Wellcome Trust/DBT India Alliance ECF, the interactions with mentors on my dummy project were invaluable. These helped me critically evaluate my application and frame it better. In general, the workshop was an extremely well-planned and balanced for instilling presentation and scientific skills.

The sessions on body-language and communication were eye-openers and helpful for any competitive grant procedure.

DR SHEETAL GANDOTRA Intermediate Fellow, IGIB, New Delhi

Dr Sheetal Gandotra is a Wellcome Trust/DBT Intermediate Fellow at the Institute of Genomics and Integrative Biology (IGIB), New Delhi. Sheetal is using various genetic and cellular tools to understand the survival and infectious mechanisms of Mycobacterium tuberculosis (Mtb). In this interview, she shares with us the impact of her current research, role of scientists and science in India and much more..

What are you working on and what impact do you hope it will have?

The second question is fundamental to understanding how lipids are mobilized from an organelle of the host to the bacilli, across several membrane barriers. We hope that this will lead to identifying targets that will limit the ability of bacteria to scavenge nutrients from the host cell- in essence, we want to bite the hand that feeds the devil.

What inspired you to become a scientist?

My teachers- Mrs Nandita Narainswamy, Dr Anil Tyagi, Dr Debi Sarkar, Dr Carl Nathan, and the late Dr Alan Houghton have been the most instrumental in driving me towards research. Their undying love for their subjects and their ability to infuse that excitement through their classes left me with more questions and encouraged me to ask those questions. Mentoring by researchers like Dr Sabine Ehrt and Dr Dirk Schnappinger encouraged me to be fearless in approaching larger questions. I think I am still

How has Wellcome Trust/DBT India Alliance funding helped you and your research?

When I moved back to India, I knew what I wanted to work on but understood the difficulties and challenges of the questions I was asking. Applying to the Wellcome Trust/DBT India Alliance in itself was a means to put these ideas on track and focus on a few of these questions. The award has allowed me to take on a high risk project but also cautioned me and advised me through the reviews about how I should manouver through the challenges. This is equally important to the generous consumable, equipment, and travel support that comes with the award. Research in a biosafety laboratory conditions for a slow growing organism like M. tuberculosis is not only time consumingbut extremely expensive, with specialized equipments dedicated for the facility. The generous funding from this award has helped me establish some of these key aspects of my research.

What keeps you going everyday?

Moreover, lack of the polyadenylation factor, CstF-64, binding prevents PAPα from accessing Star-PAP target mRNA. Altering the 3‟-UTR cis-element on Star-PAP target mRNA switches the regulatory PAP from Star-PAP to PAPα. Both the PAPs also compete with each other for binding to mRNA cleavage factor, CPSF but with a preference to Star-PAP suggesting preferential use of Star-PAP regulated sites. This specificity regulates alternative polyadenylation and PAP switch at the 3‟-UTR. CstF-64 and 3'UTR cis-element determine Star-PAP specificity for target mRNA selection by excluding PAPα.

It was evident that an epidemic as severe as that caused by the Ebola virus can have an enormous socio-economic impact in less developed countries and can consequently set them back decades with respect to development.

INDIA ALLIANCE STAFF CORNER

DR RANJANA SARMA Grants Adviser Dr Ranjana Sarma joined the organisation in September 2013 as a Grants Adviser. Apart from infusing great energy in the office and narrating numerous amusing stories, Ranjana has been involved with many activities at IA, from grants work to SciComm workshops, website and is currently the secretary of the Research Training Fellowship scheme. In this interview she reminisces about her childhood and research days, recounts how India Alliance experience has been a mixed bag, her love for martial arts and dance, and much more..

What is your background?

I am a Probashi Bangali, having spent all my childhood days in Hyderabad. I grew up in a DRDO township, surrounded by many Bengali families and celebrating Durga Puja with a gusto. My childhood was full of running around the neighborhood and climbing trees, a decisive sense of freedom. My father worked with the Defence Metallurgical Research Laboratory as a powder metallurgist, developing new material for the missiles; while mother spent a lot of time with children from other parents as a Nursery school teacher. The atmosphere at home was a fine balance of research induced chaos and education induced discipline, enhanced by the playfulness of my sister. I sailed through school as a top ranker till Bachelor's when life dealt me her lessons. I have a Bachelor's in technology in Industrial biotechnology from Anna University, Chennai. I scraped up enough grades to get recommendations letters towards my PhD application to Universities in the US. Not having learnt the lessons of life during my time in Chennai, I marched on towards bigger goals and ended up in the PhD program at the Biochemistry Department of Montana State University, USA. I rate the agonies of my graduate studies as the very best of my adult life till date and hoard each memory close. I moved to Florida for my first post-doc and then to Karolinska Institute for my second post-doc. I had the divine luck of having excellent contemporaries as my colleagues and students. But home is where the heart (could be stomach for all I care) is and it was only so long I could stay away from the Durga puja and the Hyderabadi biriyani. I headed home with my hold-all in September 2013 and these days I spend a lot of creative time negotiating the

to the ground zero of research happening in India and suddenly it all makes sense. The most stark thing I have learnt on the job is that I actually enjoy the element of hospitality management of this job.

When not busy on the job, what do you enjoy doing?

When not at my job (I wont say I am busy, just at work), I have a full life. I moved back home when I took up this job to spend time with my parents who have now retired and my grand black Labrador retriever. As a family, we have a ton of fun filled evenings and weekends, with a lot of debates thrown in. I appreciate my parents' support in making 'my' time possible in my life, as it constitutes a big chunk. I am a curious person who loves to learn and my primary hobby is to learn. Combined with my (mostly) boundless energy, this has led me to pursue several hobbies over the course of my life. I am a trained martial artist (in Aikido) and a classical dancer (Bharatnatyam and Kathak). These arts together help my left and right brain to stay in harmony.

When not being artsy, I am a bi-athlete, either running or swimming. Also, I am always up for a game of badminton. When all my energy is spent, I love listening to jugaldandis of strings and percussion. Ustaad Allah Rakha Khan and Pandit Ravi Shakar's jugalbandis are my all time, anytime, every time favorite. I also read voraciously, but my reading is not limited to any genre of books. My favorite thing to read is the newspaper every morning, specifically the business section, and the news feed on my Facebook from WIRED(http://www.wired.com/category/magazine/)
