Scientists may have just found the genetic instruction manual for regrowing lost limbs.

A new study published in PNAS by researchers from Wake Forest University, Duke University, and the University of Wisconsin–Madison identified two genes, SP6 and SP8, that appear to play a critical role in regeneration across multiple species. The axolotl salamander can regrow entire limbs, parts of its heart, brain, lungs, and spinal cord. The zebrafish can regenerate its tail fin, kidneys, spinal cord, and even damaged retinas. To test their importance, researchers used CRISPR gene-editing technology to disable these genes. Regeneration slowed dramatically or stopped altogether. When related pathways were reactivated, some regenerative abilities returned.
More than 1 million limb amputations occur worldwide every year, here is why this discovery matters. Humans already carry many of the same genes.
The blueprint may already exist within us,we simply do not know how to activate it yet. Scientists are not regrowing human limbs today, but for the first time, they may be starting to understand the biological switches that make regeneration possible. The question is no longer whether nature knows how to regrow a limb. The question is whether we can learn the same trick.

Since the beginning of human existence, every person who ever lived saw the same colours.
Red,Green,Blue and every shade between them.

Until April 2025, researchers at UC Berkeley fired precise laser pulses directly into human retinas, targeting a single type of colour-sensing cell that nature never activates alone.What the five participants saw had never been seen by any human being before.

They called it “olo” ; a blue-green so intensely saturated that it appears outside the range of colours we normally experience.

Every artist, every painter, every photographer, every person who ever looked at a rainbow lived their entire life without access to what those five people saw in a laboratory in California.

The universe may have been hiding one more colour in plain sight we just didn’t know how to look.

Scientists just brought back an animal that vanished nearly 10,000 years ago. The dire wolf, one of the Ice Age’s most iconic predators, had existed only in fossils and ancient remains. Using DNA clues from a 13,000-year-old dire wolf tooth, a biotech company edited the genome of modern grey wolves to recreate key traits of the extinct species. Three animals now exist: Romulus, Remus, and Khaleesi.
For thousands of years, extinction was considered a one-way journey. Once a species disappeared, it was gone forever. Today, science is beginning to challenge that assumption. We didn’t just study the past. We reached back 13,000 years and brought a piece of it into the present.
Science just rewrote the rules of what’s possible. Stay tuned for some more. Cheers !

The first website ever made is still live today.
You can visit it right now. Tim Berners-Lee built it in 1991 at a physics lab in Switzerland. Plain text. White background. No images. No videos.
It was literally a website explaining what a website was.
But here's the part that really matters, he could have patented it. He could have owned the entire internet, rather he gave it to the world for free instead. So,every website you have ever visited, every business built online, every connection made across continents, all of it exists because one man decided not to own it.

You can visit that first page here: https://t.co/Pj3Hm7w6Jr

Nintendo was founded in 1889, but not as a gaming company, as a playing card company in Kyoto, Japan.
For nearly 100 years they made cards, tried selling instant rice, ran a taxi service, made toys.Then one day they made a game console and changed the world.
The company behind Mario, Zelda and Pokemon started with hand painted flower cards sold to gamblers in 19th century Japan. Every great thing has a strange beginning.

The entire internet weighs around 50 grams.
Yes. You read that right.
All the electrons moving through it at this very moment weigh less than a strawberry sitting on your kitchen counter. Think about what that means for a second.
5 billion people connected. Every photo you ever uploaded. Every message you ever sent to someone you love. Every argument, every idea, every breakthrough, every memory stored online. All of it.Lighter than a piece of fruit. We built something that changed every aspect of human life and it weighs almost nothing. Maybe the most powerful things always do.

A moth changed the entire language of technology.
In 1947, Harvard Engineer "Grace Hopper" finds a real moth trapped inside a computer. She didn't just remove it. She taped it into the logbook and wrote "first actual case of bug being found." Every developer who has ever said "I'm debugging" is unknowingly referencing that one moth. That's the power of one moment. How many of you were already aware ?

What is ASMR ❓

ASMR stands for Autonomous Sensory Meridian Response, a relaxing tingling sensation that usually begins on the scalp. Moreover, It is triggered by soft sounds like whispering, tapping, brushing, or gentle movements. Nonetheless, Scientists call it a “brain tingles” phenomenon because the feeling travels down the neck and spine. Therefore, Around 20% of people experience ASMR strongly, according to global survey studies. How does it work? Consequently, Researchers believe ASMR activates the brain’s reward and social bonding systems similar to what happens during soothing touch. When does it happen? It usually occurs during calm moments, slow triggers, or repeated sounds. Why is it viral? Nonetheless, Because millions use ASMR daily for sleep, anxiety relief, and stress reduction.

🚨What is “The Overview Effect”?

The Overview Effect is a scientific term describing the mind-altering shift astronauts experience when seeing Earth from space. They report an overwhelming sense of unity, peace, and awe. Some astronauts say it feels like the brain “reboots” in a single moment. NASA notes that over 90% of astronauts reported emotional or cognitive changes after witnessing this view. It’s linked to increased activity in brain regions responsible for empathy and perspective. Why does it happen? Scientists believe the sudden realization of Earth’s fragility triggers a deep psychological reset. When does it occur? Furthermore, Usually within seconds of seeing the whole planet at once. This term reminds us how small differences seem when viewed from a higher perspective.
