Indian weddings are frequently colourful multi-day events that might run anywhere from three days to a week.

The sangeet—a musical night to greet all the wedding guests—is usually held that evening, with the main ceremony and celebration taking place on the third day.

However, these two estimates only apply to TV productions (movies and TV series) and do not include the hundreds of stage or radio plays and sketches.

When perfumers try to derive the scent of a flower, many of its aspects are lost once it’s dried and pressed into oils. So perfumers try to add those characteristics back by adding notes which make it smell more realistic. One weird way that’s done in the case of white florals, is by using Indole. Derived from coal tar, this smells like camphor and mothballs when pure, and gives a fecal scent to enhance the intensity and depth of jasmine perfumes to make these fragrances smell more like the real flower.

Here it is for everyone who has been waiting for it since our previous mention, or who simply skipped ahead till they discovered it. A mature butterfly has a lifespan of three to four weeks, although the full life cycle can last anywhere from two to eight months. There are exceptions to the rule, as there are to any rule. At least one butterfly species lives for around 24 hours, but certain migratory butterflies, such as the North American Monarch, can live for about eight months.

If you're looking to score big box office bucks, stay away from Mars. The two biggest money losers of all time both take place on that planet, with the 2012 sci-fi bomb John Carter holding the No. 2 spot with a loss of almost $127 million, outdone only by Mars Needs Moms, from a year earlier, which lost its studio more than $143 million—the worst ROI ever.

Do you believe The Walking Dead is a work of fiction? It is, but the government wants to be ready for a real-life version in any case. In 2011, the 31-page Counter-Zombie Dominance Plan, or CONPLAN 8888-11, was created. And, lest you think it's strange bureaucratic humour, the first sentence says, "This plan was not truly created as a joke."

Many people are unaware of how intelligent pigeons are. They may be taught to recognize words and to match art with its artist, but perhaps most importantly, they can be taught to distinguish between benign and cancerous growths. Researchers at the University of California, Davis, trained pigeons to distinguish between benign and malignant biopsies. The pigeons were able to "diagnose" brand new biopsies that they had never seen before after being trained how to differentiate between the two. A pigeon by itself had an accuracy of 85% on average. Their accuracy as a group approached 99%, which is expected of a doctor.
