Researchers from Czech Technical University in Prague, Czech Republic, Indian Institute of Technology, Delhi, India, and Northumbria University, UK are studying relay-assisted visible light communications to improve the indoor coverage of mobile network connectivity. Their new technique turns mobile phones into relays, forwarding data from the transmitter to the end user.
The study from IISc found a previously unidentified yeast-like symbiont inside the lac insect Kerria lacca, which gives the insect its distinctive red colour and, may also provide other nutrients in return for shelter.
