Until the advent of vinyl in the 1950s, gramophone records were made from shellac—the processed form of lac—a resinous substance produced by a group of sap-sucking insects. In India, lac has been harvested for centuries, but its economic importance surged in the early 20th century when its versatility became evident to British industry. Soon lac was a sought-after raw material. And like many other raw materials that powered Britain's industrial might, this too had to be sourced from its colonies, particularly India, the principal producer of lac in the world. Realizing the importance of lac research, the British government tapped into the existing expertise in chemistry in the Indian Institute of Science ('IISc' or 'Institute' from here on) to study lac and its products. And new researchers, including biologists, were hired to investigate this prized commodity. The story of lac research in IISc has been pieced together by Megha Prakash and Manu Rajan in this issue.
Also in this issue, Nithyanand Rao throws light on the Department of Mathematics at IISc. Conventionally, mathematics has been divided into pure and applied mathematics. They even have their own scholarly societies. However, this distinction is often superficial. Many fields of pure mathematics had their origins in solving practical problems. And pure mathematics keeps finding new applications. For instance, number theory ("Thank God that number theory is unsullied by any application," the American mathematician, Leonard Eugene Dickson, is supposed to have said) is today integral to cryptography and encryption. When it was established in 1956, the Department of Mathematics at IISc was called the Department of Applied Mathematics. But over the years, it has freed itself from the shackles of having to do research mainly to support science and engineering studies in the Institute. As its current Chair, Gadadhar Misra, says, "…we live happily without having any biases about what sort of mathematics should be done." In March this year, IISc celebrated its Open Day. We have a report from the ground by Sudhi Oberoi, who tells us about the activities that were on display at this year's event, fast becoming the Institute's most important outreach initiative. She also informs us about what goes into planning for an event of this magnitude. This issue has much more for the reader to reflect on, including insights into journalism, provided by veteran broadcaster, Mark Tully, in an interview with Nithyanand Rao and Karthik Ramaswamy.

The suggestion found support that they would like to showcase and provide from JRD Tata, then President of the Court it with an estimate of the cost of each activity. It also asks the departments to identify volunteers for manning the help desks to be set up around the campus. Based on this input, the Committee finalizes the activities and allocates the required funds.
Even as the activities are put together, the Committee focuses on advertising Open Day to the public, particularly in schools and colleges. It also works towards ensuring adequate security for the event.

"It is amazing to see some people design unconventional techniques to solve a puzzle," he tells CONNECT. The prizes for the winners included books related to mathematics and famous mathematicians.

It is the students who decide on the learning goals, plan and design the exhibits, and communicate the underlying science to visitors. S Amitash, a PhD student from the Department of Biochemistry, explained to CONNECT why he enjoyed the experience. "It helps me evolve as a researcher. The main essence of science is to communicate what we are doing in the lab. Otherwise there's no use [of doing science]", he asserts.

Light-activated iron compounds to fight cancer
Researchers from the Department of Inorganic and Physical Chemistry and the Department of Molecular Reproduction, Development and Genetics have discovered that a class of inorganic iron compounds called iron (III) catecholates can be used to kill cancerous Cour These compounds are activated when irradiated with red light. On being administered to a cancer cell, they attack its mitochondria—the organelle which produces energy—thus killing the cell. This method avoids the problems of skin sensitivity caused by organic drugs. It is also extremely selective because it is activated only by light. The team now aims to investigate the action of this anti-cancer drug in animal models.

bbrep.2016.01.015 Connect Volume 3 • Issue 2 Storing hydrogen more efficiently
One of the major challenges in using hydrogen as a fuel is finding a way to store it efficiently. A material that has a carbon base with metal atoms "decorat-ed" on it does store hydrogen, but not as much as AD and ABHISHEK KUM it theoretically could. This is because oxygen atoms too get adsorbed by the metal atoms.
Now, researchers at the Materials Research Centre have come up with a way to enhance hydrogen adsorption by "capping" the metal atoms with molecules called arenes. This alters the electronic structure of the metal atoms in such a way that the interaction with oxygen atoms is selectively blocked.
This solution could also be applied elsewhere, such as in gas sensing and catalytic systems.

INSTITUTE COLLOQUIUM: RUDRA PRATAP "Scientific research alone does not take you where you want to be. How do you overcome the temptation to stop after publishing your paper?" asked Rudra Pratap, Professor and Chairperson, Centre for Nano Science and Engineering (CeNSE), while giving an Institute Colloquium at IISc on 16 March 2016. In the talk, titled Turning Science into Technology: Narratives of Some Exhilarating Experiences, Pratap addressed the question of how to turn scientific research driven by curiosity into technology and, eventually, innovative products. He did this by drawing on some of the recent research projects from his lab as well as those of his colleagues at CeNSE, which he played a key role in founding in 2010.
Pratap and his team developed a method of etching nano-sized circuits while investigating a phenomenon known as electromigration at the nano-scale—electrons in a conductor moving under the influence of an electric field transfer their momentum to the atoms, resulting in transport of material. Pratap also spoke about how his colleagues at CeNSE are translating their research into marketable technologies.

Introducing the subject of nanotechnology, he said that the development of a form of carbon known as carbon nanotube (CNT) in 1991 was a major breakthrough in the field. Compared to steel, CNTs have superior tensile strength—100 times greater—despite being only a sixth as dense. Different forms of CNTs can be used for making various miniature sensors and actuators.
After highlighting the different approaches used in the theoretical modeling of CNTs, Gopalakrishnan spoke about his study of the propagation of mechanical waves in quasicrystals. The structure of a quasicrystal differs from that of crystals in that they are ordered but not periodic. A 3D quasicrystal tiling cannot have translational symmetry in more than two dimensions, unlike crystals which have periodicity in all three dimensions. While crystals can possess only two, three, four, and six-fold rotational symmetries, quasicrystals have other symmetry orders, such as five-fold.
The quasi-periodicity of the quasicrystals leads to two different displacement fields in the material: phonon and phason displacement modes.  Gopalakrishnan spoke about his group's work on computing the wavenumber and group-speed of the waves in these two modes in 1, 2 and 3D quasicrystals. His group has also developed characteristic equations to study the variation of wave number and group-speeds in various quasicrystals.   ANUPAM PURWAR
