According to the results of a clinical study published in the July 2011 issue of the British Medical Journal, strong proof-of-principle for utilization of diffuse reflectance spectroscopy (DRS) for early detection of oral cavity cancer has emerged. In India, oral cancer is the third most common cancer and constitutes 16.5% of all cancers with relatively high incidence rates of 21.5 and 12.8 per 1,00,000 men and women. These clinical trials were carried out at the Government Dental College, Trivandrum

A team of scientists from the Agharkar Research Institute, Pune, and the Centre for Earth Science Studies (CESS) here are carrying out detailed investigation of the peat deposits from coastal plains of tropical wet evergreen and semi evergreen forests in adjacent hinterland in Kerala, under a project funded by the Department of Science and Technology, Council for Scientific and Industrial Research (CSIR) and the Kerala State Council for Science, Technology and Environment (KSCSTE).

Periodontitis is a multifactorial inflammatory disease involving both soft and hard tissues surrounding the teeth that leads to progressive destruction of the periodontal ligament and alveolar bone resulting in clinical features such as pocket formation, gingival recession, or mobility. It is an endemic infectious disease affecting the tissues surrounding the teeth, which results in significant debilitation for about half of the affected persons. Periodontal diseases begin as gingivitis and progress slowly towards periodontitis.

Urbanization leads to micro-climate changes, particularly with regard to the thermal structure of the location. Most documented among such changes is the Urban Heat Island (UHI), which has received increasing attention during recent decades. Factors leading to the excess heat of towns are changes in the thermal characteristics of the surface, modification of the air flow patterns, reduction in evaporative cooling and heat generated by human activities.

Lakes are versatile ecosystems and they are under the threat of eutrophication and siltation. The physical characteristics of a lake provide some insight into the status of the lake. Satellite imagery analysis now plays a prominent role in the quick assessment of characteristics of a lake system in a vast area.
