The theme of #IWD2020 is #EachforEqual, because an equal world is an enabled world. Today’s #SundayScience features a few differences in the way men and women are wired. Being aware of these facts may help navigate the differences better, and strive towards #EachforEqual 
Disclaimer first: These differences are more averages and typical conditions. They don’t necessarily characterise every man or woman #SundayScience
Genetically, the DNA of men and women is 98.5% identical. The remaining differences give each gender certain unique strengths #SundayScience
Inspired by an article in today’s Eenadu (Telugu), am featuring the benefits of eating on Banana Leaf in this week’s #SundayScience
Banana leaves are packed with plant-based compounds called polyphenols, especially epigallocatechin gallate (EGCG). It contains 3 phenol rings and has very strong antioxidant properties. #SundayScience
EGCG protects our cells from oxidative damage from free radicals. Free radicals are produced by the stressors that our modern life puts on our bodies. #SundayScience
"Please write letters to Captain uncle and Khattar uncle and say, 'Please think about our health and use machines for treating stubble'," Kejriwal told the children at a Delhi school this Friday, referring to the smoke from stubble burning in Punjab and Haryana #SundayScience
Conventionally, farmers in Punjab & Haryana burnt the crop residue after harvesting paddy (Oct / Nov), to clear their fields for sowing wheat. #SundayScience
That’s the time winds blow from India's north and northwest towards east. This aerial view shows India's annual crop burning, resulting in smoke and air pollution over Delhi and adjoining areas. #SundayScience
Ice Packs or Heat Pads? #SundayScience
Been meaning to restart #SundayScience for a while; eventually hastened by an injury last week. Gave both the topic and the much-needed break on Sunday 😉
Most of us would have used ice packs or heat pads for pain relief. If you already know when to use cold or hot, see you in next week’s #SundayScience. This edition is for the others 😈
Gorgeous photo! Here's some #SundayScience about rocket exhaust (thread) /1
2/ I study rocket exhaust and how it interacts with planets' surfaces and atmosphere. There is a lot of interesting physics in this. Note how this rocket plume gets narrower right after it leaves the nozzle. That's because it comes out at lower pressure than the surrounding air.
3/ The job of the rocket nozzle is to expand the plume. If the nozzle is too small, then the plume is underexpanded, so it gets bigger right after leaving the nozzle. Here's an underexpanded plume from the Apollo Saturn V 2nd stage. See how it flares wider?
