The cell is a factory where every component needs to be in its proper place at the proper time for continued function and survival. A new study by researchers at the Indian Institute of Science, Bengaluru, explores how cells manage this remarkable feat of ensuring that the right molecules find their way to the right locations within the cell.
Toxoplasma gondii is a parasite well known for its ability to alter its hosts behaviour by targeting neurological pathways.Researchers from the University of Delhi have come up with a novel way to counter infection by this intracellular parasite, using a drug that triggers the infected cell's suicide mechanism, thus killing the parasite residing inside it.
The Centre for Ecological Sciences at the Indian Institute of Science, Bangalore, recently released a website which compiles peer-reviewed information on over 10000 species of plants. The website, which is free to access, was launched on 2 March 2019.
The caterpillar fungus (Ophiocordyceps sinensis), commonly known as Keera jari (in Hindi) and Yartsagunbu (in Tibetan) is famous for its use in traditional Asian medicine, sometimes selling at prices higher than its weight in gold. A recent study in the Indian Himalayas investigates how this fungus influences the livelihoods and economics of local communities and the possible ecological consequences of overharvesting and exploitation of this natural resource.
Salmonella typhimurium is a pathogenic bacterium that causes food-borne infections in humans. Researchers from the Regional Centre for Biotechnology, Faridabad, find that Salmonella globally alters a post-translational protein modification called Sumoylation in infected cells and manipulates the host cell’s intracellular transport machinery.
The TNQ Distinguished Lectureship Series aims to bring the Indian scientific community in close contact with world-renowned researchers and inspire young minds to choose a scientific path. This year's speaker, Helen H Hobbs from the Howard Hughes Medical Institute and University of Texas Southwestern Medical Center, will be addressing audiences on Hyderabad, Bengaluru and New Delhi on 11, 13 and 15 Feb respectively.
Plasmodium, the malaria parasite, is believed to be of simian origin. Non-human primates can act as a reservoir for this parasite, and in certain cases the parasite has been shown to be transmissible between humans and apes. Researchers led by Praveen Karanth from the Indian Institute of Science, Bengaluru recently profiled Plasmodium in multiple Indian non-human primate species, in an effort to better understand the spread of this parasite in monkey populations.
