Q1 Why does cow’s milk have somuch saturated fat if it's evolved to help a calf survive? A1 Israel Ramirez, Biopsychologist Jan 8 It seems natural toassume that cows’ milk has a lot of saturated fat because saturation is somehow good forcalves. But that’s a wrong assumption about how evolution works.Instead, the ancestor of cattle evolved a digestive system that allowed them toget a lot of energy from fiber but, as a side effect, converts that fiber intosaturated fat. Cows and other ruminants have a complex 4-chambered stomachthat allows bacteria to partially digest food for them.[1] That’s a plusbecause the bacteria convert fiber that animals can’t digest into substancesthat cattle can use. This chart shows that fibrous and other carbohydrates areconverted into substances called acetate, butyrate, and propionate.[2] That’s good because cattle can use those substances. But there’s a priceto be paid for having that advantage. Digestible carbohydrates (starch andsugar) are also partly converted into acetate, butyrate, and propionate. As a result, cattle get much lesscarbohydrate into their bodies than other animals do. Cattle can’t turn acetate, butyrate, and propionate intocarbohydrate. Instead, these substances are mostly converted into saturatedfats.And, what’s more, bacteria convert some of the unsaturated fat in foods intosaturated fats. So, cow's milk and meat contain lots of saturatedfats because that’s the most common kind of fat in their bodies. Modern cattlefarming has made the situation worse. This chart shows that feeding cattlebiodiverse plants in a field reduces saturated fat (SFA) and increasesunsaturated fat (PUFA) whereas feeding them grain indoors increases saturatedfat.[3] There’s more to this story. The totalamount of fat in milk (regardless of saturation) is related to the animal’slifestyle. Animals that nurse their childrenoften, like humans, tend to have more carbohydrate and less fat in their milk,while animals that nurse their children less often typically have rich, highfat milk. Footnotes [1]Theruminant digestive system. My note- In the TV serial Engae Brahmanan headedby late CHO, there was a discussion about cow’s milk. The query was cow’s milk for it’s calf, not for humanconsumption. Cho gave a short answer, if the calf drink all milk, even it maydie ( from my recollection). Long answer- Feed of the wild cow wasdifferent, it produced less milk, sufficient for the calf. Domesticated cowsare fed in a different manner and so more milk is produced. Q2 What are some disturbing ancienthistorical facts? A2 Edward Mboriche, Read over 10 books onHistory Updated Oct 24 The picture belowis the image of Cleopatra,a famed queen of Egypt between 51 BC - 30 BC. She was an intellectual known to have studiedmathematics, logic, debating, and science. Cleopatra was ofMacedonian descent and had little, if any, Egyptian blood, although the Greekhistorian Plutarch wrote that she alone of her house took the trouble to learn Egyptian. It might not beusual for you to know that she married her two brothers, even though some historians believe wasto keep with custom. In the end, they were both killed, one drowned, and atanother time, the other was probably poisoned on her instructions. Possible image of Cleopatra( could not be pasted) In a bid toinfluence Roman politics to enable her to regain her throne, she and Julius Caesar becamelovers. And while being married to her remaining brother Ptolemy, Cleopatra gave birth to a sonand named him Ptolemy Caesar. It cannot now be known whether Caesar(Cleopatra’s lover) or Ptolemy (Cleopatra’s brother) was the father of the boywith such a controversial name, Ptolemy Caesar. Caesarion | Biography & Facts What’s more, she killed herself with a snake. But she did somegood things with Egypt. She, built up the Egyptian economy, establishing trade withmany Arab nations. She was popular among Egyptians both because she embracedEgyptian culture and because the country was prosperous during her rule. History captured aninteresting part of her life where she was health-conscious to the extent that she bathed in milk to getparasites out of her body. My note-Nostalgic memories of seeing the filmCleopatra in SUFFIRE theatre (Chennai) in 1969 July end with my wife (with in few days after mymarriage)comes to me. Q3 What are some of the most mind-blowingfacts? A3 Anup Chouhan, Lives in Earth Updated4y HERE ARE SOME OFTHE MOST MIND BLOWING FACTS White Chocolate does not have any chocolate. Leonardo da Vincicould write with one hand and draw with the other at the same time. In an emergency, one wax crayon can burn brightly forabout 30 minutes. You can survive entirely on potatoes and butter whichprovide all necessary nutrients the human body needs.( With out water?) One gram ofyour DNA is sufficient to store all of Facebook and Google's data. The man with the longest beard in the world (17.5) feettripped over it, broke his neck and died. If a Cockroach touches a human, it will run away andclean itself. Q4 Is it considered rude to eat alone atrestaurants in India (Mumbai)? How should one approach this situation? A4 Bhuvana Rameshwar, Lives in India(1989–present)11h No. It is as fine as eating with company.There is nothing rude or selfish about it. If you live aloneor you are on some work somewhere it takes you to a restaurant due to hunger,then you naturally eat alone. You cannot call your friends or family to thatplace anytime or every time. All it needs is hunger, money to pay, nothing else matters.When I stayed alone in a small town as I had to attend contact classes /examfor my BEd degree , I often went alone to restaurants. This is some 30 plusyears ago when women didn't go to restaurants much or went only with men likehusband or father. I ate, paid and tipped too. I do that even when travellingby bus as buses stop for lunch, dinner etc in highway restaurants. Nowadays it is verycommon to see people eating alone in restaurants, bakeries, street food shops,ice cream parlours and even gobbling pani pooris or dosas from the food cartvendors. So if you arehungry, go eat. Q5 What are the science-based healthbenefits of pumpkin seeds? A5 Yummojo,A food tech company! Fri There are variousscientifically-supported health advantages of pumpkin seeds: Thanks to the magnesium they contain, they are beneficialto blood pressure and bone health. They contain a lot of zinc, a mineral that speeds up thehealing of wounds and strengthens the immune system. Phytosterols may befound in pumpkin seeds and have been demonstrated to reduce cholesterol. Antioxidants, whichneutralise potentially dangerous free radicals, may be found in abundance inthese foods as well. In addition toproviding essentialnutrients like omega-3 and omega-6 fatty acids, which are great for your brainand heart, these seeds are a great source of protein. They also possessanti-inflammatory effects, which might be useful in treating inflammatoryillnesses like osteoarthritis. They have the potential to alleviate the discomfort ofan overactive bladder and enhance the quality of your sleep. Q6 How do aeroplanes fly without flappingtheir wings? My 6-year-old daughter asked me this and I want to explain it toher in simple terms. A6 Brandon Clark,Former Flight Instructor(2004–2011)Updated 3y Ok, so the firstthing to remember here is this: Birds don't fly by flapping their wings.No,really… I'm serious. I'll repeat.*Birds don't fly by flapping their wings!* Ever watch a hawk or a seagull soar around in circleswithout flapping? This eagle is flying, like an airplane, wings steady. So why all the flapping, then?Propulsion. A birdflaps its wings to move itself forward through the air, and to climb higher inthe air. This is, of course, where planes aredifferent. To a bird, flapping its wings is no harder than youflapping your arms. Planes, onthe other hand, are (usually) made of metal. Metal doesn’t flap very well.Since we can’t make flappy metal wings, we need something else to keep theplane moving, don’t we? The solution is to make another, smaller pair of wings thatcan be moving all the time. A pair of wings to help move the plane through theair.The main wings stay steady, keeping the plane in the air. The smaller wings, on the otherhand, just spin, moving the plane along. We call these smaller wings, ofcourse, “Propellers” Yes, propellerblades are wings. They aren’t “like” wings. They are *exactly* wings, and theydo the exact same job, which is moving air. The main wing moves air down to push the plane up, and thelittle propeller wing moves air backwards to push the plane forwards. Now, if yourdaughter has trouble grasping the idea of a bird (or anything else) flyingwithout flapping wings, you can demonstrate by simply making a paper airplane.It flies, but slightly downwards. An engine and propeller (or flapping wings)would keep it flying for longer. If she asks about jets not having propellers, I thinkthat’s a bit harder to explain. A modern “jet”(technically “turbofan”) engine actually has a propeller… it’s just inside a tube, and has a wholebunch of blades (and they’re all wings, truthfully speaking). Well, I hope thishelps. I’m trying to imagine explaining this to my 6 year old niece without itall going over her head. Not an easy task. Good luck! **EDIT** Judging by some ofthe comments, I may not have made my point clear. To clarify, I’m just tryingto explain why airplanes don’t have to flap their wings. To do this, you must separate the concept of “lift” from the concept of“thrust.” Birds use their wings for both. Airplanes cannot. I’m not trying todescribe lift, that’s a whole other subject. Q7 Does a kitchen sink need to be on anoutside wall? A7 Gopala Krishnan, Former AssistantGeneral Manager 1996-2004 at Department of Telecom (1966–2004)Just now No is the answer by me. I have twosinks - one in kitchen and another in work area. The two are separated by awall, except in an area to the size of a door. One is fitted on the separating wall inside kitchen.Thisis for immediate washing, or taking water for kitchen works. The one fitted in the outer wall in the work area andthis one are connected by a 3″ PVC pipe slanting to work area under the floor.In the kitchen with a reducer of 2″ PVC pipe it is raised to 1.5 feet and sinkoutlet is simply inserted. There is an air gapbetween out let of sink and PVC pipe is raised in kitchen sink. I constructed the home in 2006. 16years till date, no foul smell, or creatures have come up. Periodically I use sink cleaner, and at least once a weekpour diluted dettol in both sinks. Q8 Neanderthals and Denisovans may haveinterbred - why do we think this, and what does it mean for our understandingof human evolution? A8 Robin Liesens, Paleontology andpaleoart enthusiast. Dec 28 It’s not a case of“they may have”, it’s a case of “it definitely happened.” Let me introduceyou to “Denisova 11”, a bone fragment from the Denisova Cave in the Altaimountains. Not only is it known that this bone fragment is 90 000 years old,DNA sequencing also showed that this individual was a girl. She died at the ageof 13. What’s more important though is that said DNA sequencingmade it clear that this girl, nicknamed Denny, was a first-generation hybrid ofa Neanderthal mother and a Denisovan father. The factthat even though there aren’t many remains of Denisovans (they’re a humanspecies only known from fragments) and yet we still find evidence ofinterbreeding with another species so easily, makes the chances extremelylikely that mixing happened regurarly. (1) But then again, this is no surprise looking at how humanspecies indeed did so on a regular basis, as is shown ingenetic studies. It’s nothing new currently, but the idea of our evolution as aspecies existing in a genetic isolation is not correct. We interbred with at least twodifferent species in our distant past and said species also have a history ofpairing up outside of their own species. (2) It’s important toremember that we, with our science and stuff, are able to look at ancient boneson a genetic level and distinguish species from species, but back in the day,when we met said species we weren’t able to do this. Out in thewilds of the mammoth steppes and ancient forests we simply met other people:people who looked a bit different, but who definitely were people just like us.Neanderthalwoman from the Middle East. artwork by Tom Björklund) Sources: Viviane Slon et al.“The genome of the offspring of a Neanderthal mother and a Denisovan father”(2017) Ewen Callaway“Evidence mounts for interbreeding bonanza in ancient human species” (2016) Q9 What happens if a vegetarian animallike a cow or elephant eats meat by mistake? A9 Alexandre Strube, Have eaten prettymuch everything Updated 5y Have a look atthose two images. Thisdeer, a vegetarian animal, is chewing some bones… Not any bones, mindyou. Those are humanbones. That being said,mostly nothing happens. But do you remember the problems withthe mad cow disease?That was spread by cows being fed with the remains of othercows. Q10 What are some ancient mysteriesand how were they solved? A10 Rose Thomas, Former Video ProductionSpecialist Updated Sep 21 The world’s biggest explosion – a blast in Russia thesize of 185 Hiroshima bombs that was felt as far away as Britain and the US – remains a mystery after expertsdebunked ‘proof’ it was a meteorite. A large fireball was seen crossingthe Siberian sky on June 20, 1908 before an eruption six miles above groundflattened 80 million trees and left charred reindeer carcases. Italian scientists spent 21 years researching the so-calledTunguska event, claiming the blue-water Lake Cheko filled a ‘missing’ impactcrater – giving rise to the theory that the phenomenon was caused by ameteorite. But a new study byRussian geologists suggests the idea is flawed, meaning the huge blast – whichlit up the night sky in Europe and even America – is still a mystery, accordingto reports in Moscow. In a review published in 2016 in the Annual Review ofEarth and Planetary Sciences, Natalia Artemieva of the Planetary Science Institute in Tucson, Arizonaexplains that the event followed a clear course. Whatever caused theevent likely entered the atmosphere at 9-19 miles per second, and would havebeen extremely fragile, destroying itself roughly six miles above Earth. The possibility of an asteroid explosion was first proposedin 1927 by Leonid Kulik, 20 years after the event.Others suggested the space-object may instead have been a comet, made up of icerather than rock, meaning it would have evaporated as it entered Earth’satmosphere. But, somescientists warn that these findings do not definitively explain the bizarreexplosion– with meteor showers being a frequent occurrence, these samples couldbe the remnants of a much smaller, unnoticed event. To some degree,the Tunguska event still remains a mystery, which scientists arecontinually working to solve – but, whether it be from a comet or asteroid,most agree that theexplosion was caused by a large cosmic body slamming into Earth’s atmosphere.
