A probe to detect palladium, a metal used in pharmaceuticals and to control vehicular exhaust. High levels of palladium in the environment can affect human beings and other living organisms.
Made of polyethylene and graphene oxide, the membrane can possibly supplement the reverse osmosis (RO) based water purification systems that are in use today. The paper will be published in the international journal Materials Chemistry A.
One possible means of bridging the gap between India’s abundant, varied natural resources and her ever-increasing requirements like clean water, food and rapid, low cost diagnostic machinery is the use of nanotechnology, write Arindam Ghosh and Yamuna Krishnan in the international journal Nature Nanotechnology.
Biomaterials are used in devices that interact with the human body during diagnostic procedures and surgery, and in tissue implants. A new biomaterial that is elastic, conducts electricity and supports living cells was fabricated at IISc recently. It has promising applications in robotics and medicine. The article is published online in the Journal of Materials Chemistry B.
The entire country offers very suitable environmental conditions for the spread of the invasive species lantana. Genetic analysis shows that the species could be adapting to different local habitat conditions. This has been published in Annals of Botany.
Photographs by Souvik Mandal, a PhD student at the Indian Institute of Science, have won accolades in the BMC Ecology Image Competition 2014. His photographs of insects feeding on plants, and a pair spotted owlets sneaking out of a nesthole in a tress, have been mentioned in the 'Highly commended' category. Souvik captured both of them at the picturesque IISc campus.
Scientists at IISc have characterized the molecular structure of protein interactions that result in infections of Staphylococcus bacteria. The molecular interactions are triggers for the progress of disease from a relatively harmless persistent stage to the virulent stage.
The Hanuman langur’s long-standing identity crisis might finally be resolved. Researchers have divided the Hanuman langur into 3-4 different species based on genetic differences; this can help in identifying unique populations that could be threatened by human activity.
Researchers from Sathees Raghavan’s group at the Department of Biochemistry have demonstrated anti-cancer properties of sapota extracts in cancerous cell lines and in laboratory mice infected with cancer. The phytochemicals (plant based chemicals) in sapota extract activates cell-death pathways. Tumour growth was inhibited, and lifespan of tumour bearing animals increased, when sapota extract was used.
