    Researcher studies crystal growth that may lead to biomaterials for both and tooth repair In nature, some organisms create their own mineralized body parts--such as bone, teeth and shells--from sources they find readily available in their environment. Certain sea creatures, for example, construct their shells from calcium carbonate crystals they build from ions found in the ocean. "The organism takes brittle carbonate and turns it into a structural shape that protects it from predators, and from being bashed against the rocks," says Lara Estroff, an associate professor of materials science and engineering at Cornell University. "There is much scientific interest in how the organism controls the crystal growth, and what mechanisms are involved in strengthening and toughening the shells, especially in comparison to their components, which are brittle."

    The Koyal Group Info Mag on Unusual square ice discovered The surprising discovery of "square ice" which forms at room temperature was made by an international team of researchers last week. The study was published in Nature by a team of scientists from UK and Germany led by Andre Geim of University of Manchester and G. Algara-Siller of University of Ulm. The accompanying review article was done by Alan Soper of Rutherford Appleton Laboratory in UK. "We didn't expect to find square ice ... We found there is something strange in terms of water going through [nanochannels]. It's going too fast. And you can't explain that by just imagining a very thin layer of liquid. Liquids do not behave in that way. The important thing to realize is that it is ice in the sense of a crystallized structure, it's not ice in the familiar sense in that it's something cold and from which you have to protect yourself," said Professor Irina Grigorieva, one of the researchers. To study the molecular structure of water inside a transparent nanoscale capillary, the team used electron microscopy. This enabled them to view individual water molecules, especially because the nano-capillary was created from graphene which was one atom thick and would not impair the electron imaging. Graphene was also chosen because it has unusual properties like conducting electricity and extreme strength. It's a 2D form of carbon that once rolled up in cylinders will form a carbon nanotube, a material, which according to The Koyal Group Info Mag, is a subject of further study because of its unusual strength. The scientists themselves were admittedly surprised at finding out that small square-shaped ice crystals formed at room temperature where the graphene capillaries are narrow (3 atomic layers of water at most). The water molecules formed into square lattices arranged in neat rows -- an arrangement that is uncharacteristic for the element that is known for forming consistent triangular structures

    PUNE: From reporting important findings on parental care among Arthropods to establishing the antiquity of metazoans (multi cell organisms), the Department of Geology and Palaeontology at the city-based Agharkar Research Institute (ARI) has come a long way in emerging as a leader in the study of trace fossils in the country. The department, whose golden jubilee celebrations begin on Friday, has made landmark contributions in the study of fossils in the past 50 years. For future research, the department aims to focus on studying the secondary porosity of rocks for exploring hydrocarbon resources as well as in establishing modern analogues to their fossil counterparts. Rajani Panchang-Dhumal, a project scientist at the department, said, "The Geology and Palaeontology department at ARI hosts a large fossil repository with over 7,000 type specimens in its collection. This repository is consulted regularly, both by research scholars as well as scientists from India and abroad. This national facility is now undergoing modernization and will soon be available on the web." [Visit Koyal Info Group Mag - Blog] Why study fossils? After a living organism died, it became buried under the ground in the layers of sediment. Once these layers become rock, the remains are said to be fossilized. They tell us about the organisms that lived on Earth from the time of the oldest fossils, about 3.8 billion years ago, to the present. By studying fossils we can learn not only about the creatures and plants of the distant past, but how they grew, what they ate, how they interacted, and many aspects of their behavior.

    Science research is a rich mine of valuable knowledge if one knows how to go about it with care and precision. As in all scientific endeavours, there is a system to follow whether one is trying to solve a simple problem such as how to kill garden weeds or improving on Einstein's Theory of Relativity. Even before the advent of the Internet and the unlimited amount of knowledge and information we have available in a matter of seconds, research has generally been misunderstood as a simple process of going to the library (Googling, for most of us today) and getting the data one needs to make a report or "thesis". Unfortunately, this is nothing but a single step in the whole process of scientific research. Academics will call this data-gathering or collating observations. The purpose of scientific research is to observe physical phenomena and to describe them in their operation or functions. The essential question is WHY. Why do things behave as they do? We can predict some things because it is how things are supposed to behave; but we want to know the causes of such phenomena. Discovering the causes through our research, we can then explain these things and use the knowledge to our advantage in many practical ways. That is, we can then build ships that can carry as many people as we can or explain that the moon, like the apple, is falling into the Earth because it is subject to the force of gravitation. Why it never crashes into the Earth is another question which Newton, fortunately, had to settle for us. Science research or what others would call the Scientific Method requires several steps to be considered one. Let us look at them with simple examples for the beginner: 1. Basic or general questions about a phenomenon Sometimes, it all starts with a casual observation followed by a curious question. W
