RetroVibesOnly+FollowParents and Their Three Sets of Twins, 1920sI came across this glass negative from the 1920s of a couple posing with their three sets of twins. I had to stop and look at it for a minute. I just can't imagine having six children and half of them are twins. They say that if you want to have twins, you need to look at the mother's side of the family. The genes for hyperovulation are passed down to the woman. So, a couple who's had twins could very well have more twins. #Twins #FamilyHistory #Genetics #VintagePhotos #Discussion #FunFacts #RetroVibes 17624Share
susanfoster+FollowDid This Tiny Gene Change Make Us Human?Scientists just found a single amino acid difference in a DNA-making protein between us and Neanderthals—and it might explain why we’re still here and they’re not. Mice with the human version of this gene acted differently, especially the females. The catch? It’s way too soon to say this is the magic answer, but it’s wild to think one tiny tweak could’ve given us an edge. Evolution is full of surprises! #History #Neanderthal #Genetics50Share
Katherine Kim+FollowAncient Europeans Weren’t Always Pale!Turns out, most ancient Europeans actually had dark skin! A new DNA study shows that lighter skin only became common about 3,000 years ago, and it wasn’t a straight path—there were all kinds of shades for thousands of years. The shift happened as people adapted to less sunlight in northern Europe, helping them make more vitamin D. Even hair and eye color got lighter over time, but that was probably just for looks, not survival. Wild how much our ancestors changed! #Beauty #Genetics #History2215Share
Zachary Gutierrez+FollowAre We Secretly Built to Hibernate?Scientists just found out humans have the same 'hibernation genes' as animals that snooze all winter! Turns out, these genes might be the key to some wild health tricks—like fighting diabetes or protecting our brains from damage. Researchers even tweaked these genes in mice and saw changes in weight and behavior. Imagine if we could tap into our inner hibernator for real-life superpowers! #Science #ScienceNews #Genetics71Share
Melvin Mosley+FollowAncient Viruses Are Hiding in Our DNA?!Turns out, about 8% of our DNA is made up of ancient viruses that infected our ancestors millions of years ago—and they’re not just dead weight! Scientists just found these viral bits actually help control which genes turn on or off, especially during early development. One viral family, MER11, even has a subtype active only in humans and chimps. Basically, our so-called 'junk' DNA is more like a secret control panel for what makes us human. Wild, right? #Science #Genetics #ScienceNews60Share
Melvin Mosley+FollowJunk DNA’s Secret Superpower RevealedTurns out, the so-called 'junk DNA' in our bodies isn’t just leftover clutter—it’s actually running the show! Scientists just found that ancient viral DNA, especially a bit called MER11, acts like a master switch for turning genes on and off during early development. Even cooler? These viral bits help shape how our brains form and might even explain what makes us different from chimps. Who knew our genetic 'trash' was actually evolutionary treasure? #Science #Genetics #ScienceNews403Share
rachel60+FollowCan You Inherit Diabetes?Turns out, diabetes does run in families, but it’s not all in your genes! Type 2 diabetes especially can be dodged or even reversed with some lifestyle tweaks. Think: eating better, moving more, and keeping your weight in check. Even if your parents had it, you’re not doomed—doctors say you’ve got more control than you think. Who knew a few healthy habits could make such a big difference? #DiabetesAwareness #HealthyLiving #Genetics #Health #BodyHealth3017Share
Jacqueline Howard DDS+FollowThe Y Chromosome’s Wild Cancer SecretTurns out, the Y chromosome isn’t just about being male—it’s got a major say in your cancer risk and how long you live. New research shows that as men age, their Y chromosome can disappear from some blood cells, and that’s linked to a much higher risk of cancer and worse outcomes. Even crazier: heavy smokers lose it faster. Scientists think checking for this missing Y could become a routine part of cancer screening for men. Who knew this tiny chromosome was such a big deal? #HealthNews #CancerResearch #Genetics #Health #BodyHealth436Share
Zachary Gutierrez+FollowTwo Dads, One Mouse: Science Just Did ThatScientists just pulled off a wild first: they raised a healthy mouse that came from two male parents—no mom needed! By tweaking certain genes, they cracked the code that usually blocks this kind of development. This could totally shake up cloning, stem cell research, and maybe even future treatments for rare genetic diseases. It’s a huge leap for biology, but don’t expect human versions anytime soon—there are still a ton of ethical and safety questions to answer. #ScienceNews #Genetics #Biotech #Science80Share
David Hernandez+FollowIron Deficiency Flips Mouse Gender?!Scientists just found that iron deficiency during pregnancy can actually cause male mouse embryos to develop female organs! Turns out, iron is crucial for activating the gene that makes male sex organs. Without enough iron, that gene gets blocked, and some XY embryos end up with ovaries instead of testes. Wild, right? This is the first time anyone’s shown nutrition can literally flip a genetic switch like this. No clue yet if it happens in humans, but it’s a total game-changer for how we think about development. #ScienceNews #Genetics #Pregnancy #Health #BodyHealth100Share
