Researchers have compared the visual abilities of butterflies and moths.

Researchers have demonstrated an improved method of capturing images through fog.

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.

Researchers from Indian Institute of Technology Bombay, Mumbai have observed a new phenomenon in a semiconductor quantum dot-- particles of nanometre (a billionth of a meter) size which are also called artificial atoms) made of Cu₂ZnSnS₄  (CZTS). By shining Ultra Violet (UV) light, on the quantum dots immersed in an electrolyte, they noticed an increase in its capacitance. The effect could be engineered to serve as photocapacitors- capacitors that are charged using light.
