TIFR’s superconductor discovery: Where are the reports?

On December 2, physicists from the Tata Institute of Fundamental Research (TIFR) announced an exciting discovery: that the metal bismuth becomes a superconductor at a higher temperature than predicted by a popular theory. Granted the theory has had its fair share of exceptions, the research community is excited about this finding because of the unique opportunities it presents in terms of learning more, doing more. But yeah, even without the nuance, the following is true: that TIFR physicists have discovered a new form of superconductivity, in the metal bismuth. I say this as such because not one news outlet in India, apart from The Wire, reported the discovery, and it’s difficult to say it’s because the topic was too hard to understand.

This was, and is, just odd. The mainstream as well as non-mainstream media in the country are usually quick to pick up on the slightest shred of legitimate scientific work and report it widely. Heck, many news organisations are also eager to report on illegitimate research – such as those on finding gold in cow urine. After the embargo on the journal paper lifted at 0030 hrs, I (the author of the article on The Wire) remained awake to check if the story had turned out okay – specifically, to check if anyone had any immediate complaints about its contents (there were two tweets about the headline and they were quickly dealt with). But then I ended up staying awake until 4 am because, as much as I looked on Google News and on other news websites, I couldn’t find anyone else who had written about it.

Journal embargoes aren’t new, nor is it the case that journalists in India haven’t signed up to receive embargoed material. For example, the multiple water-on-Mars announcements and the two monumental gravitational-waves discoveries were all announced via papers in the journal Science, and were covered by The Hindu, The Telegraph, Times of India, Indian Express, etc. And Science also published the TIFR paper. Moreover, the TIFR paper wasn’t suppressed or buried in the embargoed press releases that the press team at Science sends out to journalists a few days before the embargo lifts. Third, the significance of the finding was evident from the start; these were the first two lines of the embargoed press release:

Scientists from India report that pure Bismuth – a semimetal with a very low number of electrons per given volume, or carrier concentration – is superconducting at ultralow temperatures. The observation makes Bismuth one of the two lowest carrier density superconductors to date.

All a journalist had to do was get in touch with Srinivasan Ramakrishnan, the lead author of the paper as well as the corresponding author, to get a better idea of the discovery’s significance. From my article on The Wire:

“People have been searching for superconductivity in bismuth for 50 years,” Srinivasan Ramakrishnan, the leader of the TIFR group, told The Wire. “The last work done in bismuth found that it is not superconducting down to 0.01 kelvin. This was done 20 years ago and people gave up.”

So, I’m very curious to know what happened. And since no outlets apart from The Wire have picked the story up, we circle back to the question of media coverage for science news in India. As my editor pointed out, the major publications are mostly interested in stuff like an ISRO launch, a nuclear reactor going critical or an encephalitis outbreak going berserker when it comes to covering science, and even then the science of the story itself is muted while the overlying policy issues are played up. This is not to say the policies are receiving undeserving coverage – they’re important, too – but only that the underlying science, which informs policy in crucial ways, isn’t coming through.

And over time this disregard blinds us to an entire layer of enterprise that involves hundreds of thousands of our most educated people and close to Rs 2 lakh crore of our national expenditure (total R&D, 2013).

A gamma ray telescope at Hanle: A note

A gamma ray telescope is set to come up at Hanle, Ladakh, in 2015 and start operations in 2016. Hanle was one of the sites proposed to install a part of the Cherenkov Telescope Array, too. A survey conducted in the 1980s and 90s threw up Hanle as a suitable site to host telescopes because “it had very clear and dark skies almost throughout the year, and a large number of photometric and spectroscopic nights,” according to Dr. Pratik Majumdar of the Saha Institute of Nuclear Physics, Kolkata.

The Cherenkov Telescope Array will comprise networked arrays of telescopes in the northern and southern hemispheres to study and locate sources of up to 100-TeV gamma rays. Dr. Subir Sarkar at Oxford University had told me at the time that “the CTA southern observatory will be able to study the center of the galaxy, while the northern observatory [of which the Hanle telescope will be a part] will focus on extra-galactic sources.” Another Cherenkov telescope, called HAGAR, has been in operation at Hanle since 2008, according to Dr. Majumdar.

Although Hanle was in the running around July 2013, its name was lifted from the list by April 2014. Dr Sarkar had written to me earlier,

“I realize it is interesting to mention to your readers that Hanle, Ladakh is a proposed site. However I should tell you that this is very unlikely – not because the site is unsuitable (in fact it is excellent from the scientific point of view) but because the Indian Govt. does not permit foreign nationals to visit there. I know a French postdoc who was at TIFR for several years and is now working with Pratik Majumdar at SINP … even he has been unable to get clearance to go to Hanle! I do think India needs to be more proactive about opening up to people from abroad, especially in science and technology, in order to benefit from international collaboration. Unfortunately this is not happening!”

This is ‘closedness’ showed up in another place recently: at the INO, Theni.

Dr. Majumdar added,

Almost all the research institutes and installations in India need to pull up their socks particularly in case of dealing with such bureaucratic procedures [of letting foreign scientists move around inside the country]. We do need to change this inhibitive attitude. BARC is another case where bringing in foreigners for work/visits is quite a big hassle and that is not just for foreigners, even any Indian national is not allowed to take laptops/CDs/other electronic items inside BARC without special permissions. This is unthinkable to me in today’s age. So, even though it does not sound very bad always, there are various layers of inhibition where at various levels this has to be fought.

He added that HAGAR operated with similar restrictions. In fact, in 2018, another gamma-ray observatory is set to be installed in Hanle by TIFR and BARC. So we have local scientific institutions asking for more international participation and eager to deliver results, and on the other hand annoying bureaucratic restrictions on those who decide to participate.
