Researchers at Tata Institute of Fundamental Research (TIFR), Mumbai have identified a new function for Serotonin, a monoamine neurotransmitter. The serotonin may help treat neurological diseases.The results of the study were published in the journal "Proceedings of the National Academy of Sciences (PNAS)".A research paper jointly led by Vidita A. Vaidya and UllasKolthur-Seetharam from TIFR, in collaboration with Ashok Vaidya from KHS (Kasturba Health Society), had found that stress buster Serotonin is involved in the generation of new mitochondria in neurons, increased cellular respiration and fuel (ATP- adenosine triphosphate) in the cell.The recent discovery establishes that serotonin signaling could be used to prevent mitochondrial abnormalities and neuronal loss.

Chennai Central Railway station in Tamil Nadu, officially known as Puratchi Thalaivar Dr. M.G. Ramachandran Central Railway Station with its 57-character count missed the chance of having the title of world's longest railway station name by an alphabet. The title was won by Llanfairpwll railway station in Wales, also known for its 58 letters long name 'Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch'. Although, the erstwhile Chennai Central railway station which was renamed after the legendary actor-turned-politician Dr. M.G. Ramachandran is still the longest railway station name in India. The other railway stations in India with long names are Karnataka's Krantivira Sangolli Rayanna Bengaluru City station, Venkatanarasimharajuvaripeta in Andhra Pradesh and Chhatrapati Shivaji Maharaj Terminus in Maharashtra.

Scientists from Stanford University, Shanhui Fan along with Masashi Ono have demonstrated for the first time that it is possible to produce a measurable amount of electricity in an infrared photodiode from the coldness of the universe.The infrared semiconductor uses the temperature difference between Space and Earth to produce the electricity. The study was published in a journal named Applied Physics Letters. The new device has generated about 64 nanowatts per square meter. According to the theoretical calculations, the device can generate almost 4 watts per square meter, roughly one million times what practically generated. In the new technology, the negative illumination effect allows electrical energy to be harvested as heat leaves a surface.

The research team from IIT Madras has used a multi-lingual Optical Character Recognition (OCR) scheme to develop a method for reading documents in Bharati script. The researchers have also developed a finger-spelling method that can be used by hearing-impaired persons to generate sign language, in collaboration with TCS Mumbai. The Bharati script is a conglomeration of 9 Indian languages, namely, Devnagari, Bengali, Gurmukhi, Gujarati, Oriya, Telugu, Kannada, Malayalam and Tamil. In the last 10 years, Professor V. Srinivasa Chakravarthy's research team at IIT Madras has worked on developing this script. he OCR scheme first segments the document into 2 parts, text and non-text. After this, the text is separated into paragraphs, sentences words and letters, where every letter is recognised as a character in ASCII (American Standard Code for Information Interchange) or Unicode. The letter again has several components, namely, the basic consonant, consonant modifiers, vowels.
