Prebiotics are the lesser-known gut-health promoters which serve as food for good bacteria inside the gut. "We found that dietary prebiotics can improve non-REM (random eye movement) sleep, as well as REM sleep after a stressful event," said Robert Thompson, a PhD researcher at University of Colorado Boulder in the U.S. Prebiotics are dietary fibres found naturally in foods like artichokes, raw garlic, leeks and onions.

When beneficial bacteria digest prebiotic fibre, they not only multiply, improving overall gut health, but they also release metabolic by-products. Researchers fed three-week-old male rats a diet of either standard chow or chow that included prebiotics. They then monitored the rats' body temperature, gut bacteria and sleep-wake cycles — using electroencephalogram (EEG), or brain activity testing over time. Findings revealed that the rats on the prebiotic diet spent more time in non-rapid-eye-movement (NREM) sleep, which is restful and restorative, than those on the non-prebiotic diet.

How can sleep wake cycles be monitored?

I don’t know whether the Madras Photographic Society has anything to do with the recently-publicised Chennai Photo Biennales, the first last year and the next scheduled for 2018, but participant or not, it certainly deserves a bow for being the country’s first photographic society. Its founder was an Army doctor, Alexander Hunter. The Society was founded in 1857, shortly after Lord Canning arrived as Governor-General. Canning and Lady Canning, both photography enthusiasts, were responsible for creating the famed Government series, The People of India. Hunter had still earlier, in 1850, privately started the Madras School of Arts. The School, taken over by Government in 1852, moved from Popham’s Broadway to Poonamallee High Road. There, he and an eight-member committee revised the syllabus, offering two streams, Industrial and Artistic. Hunter was put in charge of the institution, renamed the Government School of Industrial Arts, in 1855. It was the first formal school of Art in the country. In it, Hunter introduced Photography.

Hunter retired in 1868, to be succeeded by Robert Chisholm. No mean photographer, Hunter encouraged the School, it is now the Government College of Arts and Crafts to build up a photographic collection. Unfortunately, little is left of his work, especially the monuments of South India captured by Government photographer Linnaeus Tripe and his assistant C Iyahsawmi. Hunter himself did a series of pictures of the ‘Seven Pagodas’ (Mahabalipuram) and worked with his wards on photographs of the five hill tribes of the Nilgiris. It was at a prize-giving of the School that Hunter urged the Governor to provide it more suitable premises. They came up on the PH Road site in Chisholm’s time and to his design — and remain there.
