Uploaded 29-01-19 -- Flannery O’Connor scribbled tales of outcasts, intruders and misfits staged in the world she knew best: the American South.

    What actually triggers high cholesterol? - Hei Man Chan

    Travel into the digestive system to learn about cholesterol, and find out what the difference is between LDL and HDL cholesterol. -- In 1968, the American Heart Association made an announcement that would influence people’s diets for decades: they recommended that people avoid eating more than three eggs a week.

    The legend of the brothers who outmaneuvered the demon queen - Malay Bera

    Dig into the Bengali tale of brothers Neelkamal and Lalkamal, two princes seeking to end the reign of demons in their kingdom. -- Achinpur was on the precipice of demonic takeover. A mysterious woman beguiled the king and infiltrated the royal family. But she wasn’t human; under her beautiful façade lurked an insatiable appetite for flesh. One night, the demon queen devoured the king's sons — but the princes managed to evade death. Malay Bera shares the tale of their quest to free the kingdom from the scourge of demons. Lesson by Malay Bera, directed by Ahmad Thabit, Samaka Studio. Although this folktale exists in multiple oral variants across the Bengali-speaking world, this video is based on a variant akin to the better-known literary version, "Neelkamal and Lalkamal", from Thakurmar Jhuli (1907), an anthology of Bengali folktales collected by Dakshinaranjan Mitra Majumdar in the early 20th century.

    Why do cats have vertical pupils? - Emma Bryce

    Dive into the incredible diversity of animal pupils, and how the different shapes indicate the animal’s role in an ecosystem. -- Peering into the eyes of different animals, you’ll see some extraordinarily shaped pupils.
