• In 2022, Google quietly wired Apple a mind-blowing $20 billion. There was no scandal. No lawsuit. No broken systems. Just one of the most strategic, low-key deals in the history of tech.

    And yet, most people don’t even know it happened.

    All Google wanted was one thing—to remain the default search engine on every iPhone, iPad, and MacBook around the world. That’s it. One slot. One silent placement that gave Google access to more than half the world’s mobile traffic.

    That deal, that little setting most users never even change, fuels over a third of Google’s mobile ad revenue. Because when you open Safari and search something, it’s Google that serves the result. And Apple? Well, they collect a massive cut of that cash.

    Back in 2014, this deal was just $1 billion. But as the stakes rose and iPhones spread across the globe, the price tag climbed with them. Fast forward a few years, and Google is paying Apple between $18 to $20 billion every single year. That’s not just pocket change—that’s more than the GDP of some countries.

    Behind the scenes, this partnership is so valuable that Google considers losing it a “Code Red” event. They literally have internal crisis drills in case Apple ever walks away. On the flip side, Apple makes so much from this single partnership that some say it covers nearly 20% of its operating income.

    What makes it even more fascinating is that Apple doesn’t even offer its own search engine. And despite being tech rivals in public, Apple continues to call Google the “best search engine” while raking in billions.

    When Microsoft tried to get in on the deal, offering Apple 90% of Bing ad revenue, Apple didn’t even flinch. They stayed with Google. Not because they love them. But because the deal works—and it's invisible to most users.

    This quiet alliance isn’t just lucrative—it’s also controversial. U.S. regulators have opened antitrust lawsuits over this deal, arguing that it locks out competition and gives Google unfair dominance. But while the courts argue, the checks keep clearing.

    For entrepreneurs and founders, this story holds powerful lessons.

    Google didn’t pay for ads. They paid for position.

    And that position—being the default—unlocked one of the most valuable revenue streams in modern tech. Sometimes in business, the best seat at the table is not the loudest one. It’s the one people overlook. It’s the one baked into habit.

    It also shows that traffic is the new gold. Not the app. Not the content. But the ability to direct and control where attention flows. Apple could have built their own search engine. But they didn’t need to. Letting someone else win—while getting paid billions—is a different kind of power.

    We often think business success comes from being loud, innovative, or disruptive. But sometimes, the real power lies in quiet control. In unseen agreements. In being the one who decides what happens next—not necessarily the one who builds it.

    And so, two of the biggest tech giants, who seem like enemies on the surface, are actually tied together in one of the smartest, most profitable deals ever made.

    It’s a silent alliance. A strategic position. And a masterclass in how power really works in the modern world.

    Let it sink in: Google pays Apple billions… just to stay in your search bar.

    That’s the level of positioning every entrepreneur should aim for.

    Not just to be seen—but to be default.

    It does appear there is a pawn in this game. Can you guess who it is?

  • In 1998, Yahoo made the most expensive mistake in corporate history.

    Two kids begged them to buy their tiny website for $1m.

    But Yahoo’s CEO called it "a waste of time".

    11 years later, those kids wiped Yahoo off the internet.

    Here’s the shocking story of Yahoo's downfall.

    1994, Yahoo started as a college project I
    A website built to help people find information online.

    By 1996, it became the largest online platform at a $33.8M valuation.

    They had the users, the hype, and the cash.
    But cracks were forming…

    Then in 1998, two Stanford students, Larry Page and Sergey Brin, built a revolutionary search engine.

    Their algorithm made Yahoo’s search look ancient.

    Unlike Yahoo’s directory-style listings, where human editors manually organized websites,

    These guys built something different.

    Their secret sauce? PageRank.

    Instead of just matching keywords, their algorithm ranked websites based on how many other sites linked to them, like academic citations.

    The more links a site had, especially from other credible pages, the higher it ranked.

    The result? Faster, smarter, more relevant search results.

    They named it Google.

    And when they offered to sell it to Yahoo for just $1 million, Yahoo laughed.

    “Search isn’t our focus,” they said.

    They had no idea that tiny algorithm would become their executioner.

    They turned it down, saying it wasn’t “worth their time.”

    But instead of killing the idea completely, Yahoo made the worst business decision in tech history

    They plugged Google search into Yahoo’s homepage.

    Their thinking? "Let users still come to Yahoo, but let Google handle the search behind the scenes."

    Smart in the short term.
    A catastrophe in the long run.

    Because here’s what happened:

    People LOVED Google

    It was fast, simple, and accurate, everything Yahoo search wasn’t.

    So each time someone used Yahoo, they were unknowingly falling in love with Google.

    Yahoo gave Google the exposure it needed to explode.

    And explode it did.

    Suddenly, Yahoo panicked.

    They came crawling back and offered to buy Google for $3 billion.

    But Google said, “Nah. We’re worth $5B now.”

    Yahoo laughed… and walked away again.

    Another trillion-dollar blunder, served cold with ego and regret.

    Still in denial, Yahoo doubled down.
    They decided to build their own walled ecosystem.

    They launched platforms for news, sports, shopping, and finance.

    They didn’t want to send users out, they wanted to keep them in.
    All in the name of ad revenue.

    Meanwhile, the internet exploded.
    Websites multiplied like wildfire.
    And Yahoo’s outdated, slow search system couldn’t keep up.

    So users did what users always do when something sucks:

    They left.

    They went to Google, where the search was smarter, cleaner, lightning-fast.
    No clutter. No noise. Just results.

    And then… Google played its masterstroke:

    AdWords.

    A genius idea: Businesses could bid to show up on Google search but only pay if someone clicks.

    Ads that felt natural. Relevant. Contextual.

    Every single search became a money machine.
    Google was printing cash.
    Advertisers loved it. Users didn’t mind it.

    Google didn’t just win search.
    They turned it into a business empire.

    While Yahoo? They were busy shopping.

    Buy every Tech. Company to remain relevant

    $5.7B for Broadcast com.
    $1.1B for Tumblr.
    Billions poured into acquisitions, most of them flops.

    They weren’t innovating.
    They were trying to buy relevance.

    But Google kept building: Gmail. Maps. Android. YouTube. Chrome.

    Every product was a hit.
    Every move, strategic. User-first.

    By 2009, Yahoo had had enough.

    They gave up on search completely.
    Handed it over to Microsoft.

    Let Bing take the wheel.

    Yes, Yahoo literally gave its core product to a competitor.

    That was the beginning of the end.

    In 2016, Yahoo was sold to Verizon for just $4.48 billion.
    A sad fall from a $125B peak.

    Once a titan. Now a tech ghost.

    So what really went wrong?

    Google had vision.

    They took bold bets. Focused on people. Played the long game.

    Yahoo was scattered.
    Short-sighted. Chasing quick wins and shiny distractions.

    In the end, Google didn’t just outperform Yahoo.
    They buried them.

    Because sometimes, playing it safe is the most dangerous move of all.

    Yahoo had the chance to buy Google twice.

    But they said no.

    And it cost them everything.

    So what can we learn from Yahoo’s downfall?

    Plenty.

    Here are the cold, hard lessons:

    - Never ignore innovation because it’s “too small.”
    That tiny idea you call a “waste of time” today could be your biggest threat tomorrow.

    - If you don't serve your users, someone else will.
    Yahoo chased ads. Google chased users. Guess who won?

    - Don’t fear disruption, own it.
    Yahoo was too comfortable. Too focused on preserving the old.
    Google rewrote the rules and owned the future.

    - Exposure is power.
    Yahoo thought they were “helping” Google by showing their results.
    They were unknowingly building their rival's brand on their own homepage.

    - You can’t outspend strategy.
    Yahoo thought buying companies was the answer.
    But real dominance is built, not bought.

    - Simplicity scales.
    While Yahoo was cluttered with portals and ads, Google kept it clean.
    Sometimes the simplest product wins.

    - Vision > Vanity.
    Google had a long-term vision.
    Yahoo wanted to look big fast.
    The difference? One is still around. The other is a tech relic.

    In business, it’s not about who starts first.
    It’s about who adapts, who listens, and who leads.

    Yahoo had the throne.
    But they gave it away twice.

    So remember this:

    The most expensive mistake in business isn’t doing the wrong thing.
    It’s ignoring the right one.

  • A major new study out of Brazil has revealed alarming evidence that heavy drinking can leave a lifelong mark on the brain. Researchers at the University of São Paulo analyzed the brains of 1,781 people, comparing autopsy findings with detailed lifetime drinking histories. The results were stark: heavy drinkers were 133% more likely to have vascular brain lesions, damage to small blood vessels, compared to lifelong abstainers. Even those who had quit heavy drinking years before were 89% more likely to show this kind of brain injury.

    The dangers don’t end there. The study found that heavy drinkers had a 41% higher chance of developing tau protein tangles, a classic hallmark of Alzheimer’s disease, while former heavy drinkers had a 31% higher risk. Perhaps most sobering, people with a history of heavy alcohol use died on average 13 years earlier than those who never drank. The researchers also noted lower brain mass-to-height ratios and more reported memory and cognitive problems in these groups, even if some effects weren’t as clear in living moderate or heavy drinkers.

    While the study relied partly on family reporting for drinking habits and couldn’t conclusively prove that alcohol alone caused all the brain damage, it adds substantial weight to the list of reasons for caution. The risks of drinking, especially heavy or sustained use, may last long after the last drink is poured.

  • Human hair contains trace minerals like calcium, iron, magnesium, and zinc, which are essential for its growth and structure. These minerals, present in minute quantities, originate from a cosmic process tied to ancient star explosions, known as supernovae.

    Stars, during their lifecycle, fuse lighter elements like hydrogen and helium into heavier ones, including carbon, oxygen, and the aforementioned minerals. When massive stars exhaust their fuel, they collapse and explode in a supernova, dispersing these elements into space.

    Over billions of years, these ejected materials mix with interstellar gas and dust, forming new stars and planets. Our solar system, including Earth, formed from such enriched cosmic clouds about 4.6 billion years ago. The minerals in Earth’s crust, water, and living organisms—including humans—trace back to these stellar events.

    Calcium strengthens hair’s keratin structure, while iron supports follicle health. These elements enter our bodies through food and water, ultimately incorporating into hair.

    Thus, the trace minerals in every strand connect us to the universe’s ancient history, reflecting the remnants of stars that exploded long before our planet existed, a testament to our cosmic origins.

  • আইনস্টাইনের মস্তিষ্কের রহস্য: সাধারণ থেকে অসাধারণের খোঁজ!

    কিংবদন্তী বিজ্ঞানী আলবার্ট আইনস্টাইন (Albert Einstein)-এর বুদ্ধিমত্তা ছিল প্রবাদপ্রতীম। কিন্তু তার এই অবিশ্বাস্য প্রতিভার উৎস কি তার মস্তিষ্কের কোনো বিশেষ গঠনের মধ্যে লুকিয়ে ছিল? এই প্রশ্নের উত্তর খোঁজার যাত্রাটি এক বিস্ময়কর কাহিনীর জন্ম দিয়েছিল।

    ১৯৫৫ সালে প্রিন্সটন, নিউ জার্সি, মার্কিন যুক্তরাষ্ট্রে (Princeton, New Jersey, USA), মহাধমনী / অ্যাওর্টা ফেটে যাওয়ার (ruptured aorta) কারণে আলবার্ট আইনস্টাইন শেষ নিঃশ্বাস ত্যাগ করেন। তার মৃত্যুর পর ময়নাতদন্তের দায়িত্বে ছিলেন ডক্টর টমাস হার্ভে (Dr. Thomas Harvey)। আইনস্টাইনের ইচ্ছানুযায়ী তার দেহ দাহ করা হলেও, ডক্টর হার্ভে অনুমতি ছাড়াই গোপনে মস্তিষ্কটি নিজের কাছে রেখে দেন। তার উদ্দেশ্য ছিল, এই অসাধারণ মস্তিষ্কটি নিয়ে গবেষণা করে এর রহস্য উন্মোচন করা। শুধু তাই নয়, তিনি আইনস্টাইনের চোখ দুটিও সংরক্ষণ করেছিলেন।

    কিন্তু এরপর কেটে যায় বহু বছর, ডক্টর হার্ভের প্রতিশ্রুত কোনো গবেষণাপত্রই প্রকাশিত হয় না। বিষয়টি প্রায় চাপা পড়ে গিয়েছিল। অবশেষে ১৯৭৮ সালে, একজন রিপোর্টার বহু খোঁজাখুঁজির পর কানসাসে ডক্টর হার্ভের হদিস পান। সেখানে এক অবিশ্বাস্য দৃশ্য অপেক্ষা করছিল। হার্ভে তার অফিসের একটি বিয়ার কুলার (beer cooler) থেকে বের করে আনেন কয়েকটি মেসন জার(Mason Jar), যার ভেতরে ফরমালিনে ডোবানো ছিল আইনস্টাইনের মস্তিষ্কের ২৪০টি খণ্ডাংশ।

    হার্ভে জানান, তিনি মস্তিষ্কটির নমুনা সারা দেশের শীর্ষ বিজ্ঞানীদের কাছে পাঠিয়েছিলেন। প্রাথমিকভাবে বেশিরভাগ বিজ্ঞানীই বলেছিলেন যে, এটি দেখতে আর দশটা সাধারণ মস্তিষ্কের মতোই।

    তবে পরবর্তীকালের গভীর গবেষণা কিছু বিস্ময়কর তথ্য সামনে নিয়ে আসে। দেখা যায়, আইনস্টাইনের মস্তিষ্কের গঠন সাধারণ মানুষের চেয়ে কিছু ক্ষেত্রে আলাদা ছিল:

    * তার মস্তিষ্কের মিড-ফ্রন্টাল লোব (mid frontal lobe)-এ সাধারণ মানুষের মতো তিনটি নয়, বরং চারটি ভাঁজ ছিল।
    * তার উভয় প্যারাইটাল লোব (parietal lobe) ছিল অদ্ভুত আকারের এবং অপ্রতিসম। গণিত, যুক্তি এবং স্থানিক চিন্তার (spatial thinking) সাথে যুক্ত মস্তিষ্কের এই অংশটি তার ক্ষেত্রে বেশ প্রশস্ত ছিল, যা তার গাণিতিক প্রতিভার কারণ হতে পারে বলে মনে করা হয়।
    * তার ডান মোটর স্ট্রিপ (motor strip)-এ একটি বিশেষ স্ফীত অংশ ছিল, যা সাইন অফ ওমেগা (Sign of Omega) নামে পরিচিত। এই বৈশিষ্ট্যটি সাধারণত দক্ষ বেহালাবাদকদের মধ্যে দেখা যায়, যারা তাদের বাম হাতের আঙুল নিপুণভাবে ব্যবহার করেন। আর আইনস্টাইন যে সারাজীবন বেহালা বাজাতে ভালোবাসতেন, তা তো সবারই জানা।
    * মস্তিষ্কের দুটি গোলার্ধকে সংযোগকারী কর্পাস ক্যালোসাম (corpus callosum) অংশটি ছিল বেশ পুরু। এর ফলে হয়তো তার মস্তিষ্কের উভয় অংশের মধ্যে যোগাযোগ ব্যবস্থা অনেক বেশি শক্তিশালী ছিল।
    * তার নিউরনগুলোও বেশ ঘন সন্নিবিষ্ট ছিল এবং নিউরন প্রতি গ্লিয়াল কোষের (glial cells) সংখ্যাও ছিল বেশি, যা দ্রুত তথ্য প্রক্রিয়াকরণে সহায়ক হতে পারে।

    তবে এই গবেষণা নিয়ে বিতর্কও কম হয়নি। সমালোচকদের মতে, মাত্র একটি মস্তিষ্ক পরীক্ষা করে কোনো নিশ্চিত সিদ্ধান্তে আসা সম্ভব নয় এবং একে আইনস্টাইনের প্রতিভার একমাত্র কারণ হিসেবে প্রতিষ্ঠা করাটাও অবৈজ্ঞানিক।

    এই চুরির জন্য ডক্টর হার্ভেকে চরম মূল্য দিতে হয়েছিল। তিনি তার মেডিকেল লাইসেন্স এবং কর্মজীবন—দুটোই হারান। অবশেষে, মস্তিষ্কের বেশিরভাগ অংশই প্রিন্সটন মেডিকেল সেন্টারে ফিরিয়ে দেওয়া হয়, যেখানে তা আজও সযত্নে সংরক্ষিত আছে।

    তবে আপনি যদি এই কিংবদন্তী মস্তিষ্কের অংশবিশেষ নিজের চোখে দেখতে চান, তারও সুযোগ রয়েছে। ফিলাডেলফিয়ার মুটার মিউজিয়াম (Philadelphia Mütter Museum)-এ আইনস্টাইনের মস্তিষ্কের কিছু খণ্ডাংশ আজও প্রদর্শনের জন্য রাখা আছে, যা এক কিংবদন্তী বিজ্ঞানীর মৃত্যুর পরেও তাকে ঘিরে তৈরি হওয়া রহস্যের সাক্ষী হয়ে রয়েছে।

    আইনস্টাইনের মস্তিষ্কের রহস্য: সাধারণ থেকে অসাধারণের খোঁজ! 🧠✨🔍 কিংবদন্তী বিজ্ঞানী আলবার্ট আইনস্টাইন (Albert Einstein)-এর বুদ্ধিমত্তা ছিল প্রবাদপ্রতীম। 👨‍🔬💡 কিন্তু তার এই অবিশ্বাস্য প্রতিভার উৎস কি তার মস্তিষ্কের কোনো বিশেষ গঠনের মধ্যে লুকিয়ে ছিল? এই প্রশ্নের উত্তর খোঁজার যাত্রাটি এক বিস্ময়কর কাহিনীর জন্ম দিয়েছিল। 📖 ১৯৫৫ সালে প্রিন্সটন, নিউ জার্সি, মার্কিন যুক্তরাষ্ট্রে (Princeton, New Jersey, USA), মহাধমনী / অ্যাওর্টা ফেটে যাওয়ার (ruptured aorta) কারণে আলবার্ট আইনস্টাইন শেষ নিঃশ্বাস ত্যাগ করেন। 💔 তার মৃত্যুর পর ময়নাতদন্তের দায়িত্বে ছিলেন ডক্টর টমাস হার্ভে (Dr. Thomas Harvey)। 🧑‍⚕️ আইনস্টাইনের ইচ্ছানুযায়ী তার দেহ দাহ করা হলেও, ডক্টর হার্ভে অনুমতি ছাড়াই গোপনে মস্তিষ্কটি নিজের কাছে রেখে দেন। 🤫🧠 তার উদ্দেশ্য ছিল, এই অসাধারণ মস্তিষ্কটি নিয়ে গবেষণা করে এর রহস্য উন্মোচন করা। শুধু তাই নয়, তিনি আইনস্টাইনের চোখ দুটিও সংরক্ষণ করেছিলেন। 👀 কিন্তু এরপর কেটে যায় বহু বছর, ডক্টর হার্ভের প্রতিশ্রুত কোনো গবেষণাপত্রই প্রকাশিত হয় না। ⏳ বিষয়টি প্রায় চাপা পড়ে গিয়েছিল। অবশেষে ১৯৭৮ সালে, একজন রিপোর্টার বহু খোঁজাখুঁজির পর কানসাসে ডক্টর হার্ভের হদিস পান। 📰🕵️‍♀️ সেখানে এক অবিশ্বাস্য দৃশ্য অপেক্ষা করছিল। হার্ভে তার অফিসের একটি বিয়ার কুলার (beer cooler) থেকে বের করে আনেন কয়েকটি মেসন জার(Mason Jar), যার ভেতরে ফরমালিনে ডোবানো ছিল আইনস্টাইনের মস্তিষ্কের ২৪০টি খণ্ডাংশ। 🧪🧠✂️ হার্ভে জানান, তিনি মস্তিষ্কটির নমুনা সারা দেশের শীর্ষ বিজ্ঞানীদের কাছে পাঠিয়েছিলেন। 🔬 প্রাথমিকভাবে বেশিরভাগ বিজ্ঞানীই বলেছিলেন যে, এটি দেখতে আর দশটা সাধারণ মস্তিষ্কের মতোই। 🤷‍♂️ তবে পরবর্তীকালের গভীর গবেষণা কিছু বিস্ময়কর তথ্য সামনে নিয়ে আসে। 🔬🔍🤯 দেখা যায়, আইনস্টাইনের মস্তিষ্কের গঠন সাধারণ মানুষের চেয়ে কিছু ক্ষেত্রে আলাদা ছিল: * 💥 তার মস্তিষ্কের মিড-ফ্রন্টাল লোব (mid frontal lobe)-এ সাধারণ মানুষের মতো তিনটি নয়, বরং চারটি ভাঁজ ছিল। * 💥 তার উভয় প্যারাইটাল লোব (parietal lobe) ছিল অদ্ভুত আকারের এবং অপ্রতিসম। গণিত, যুক্তি এবং স্থানিক চিন্তার (spatial thinking) সাথে যুক্ত মস্তিষ্কের এই অংশটি তার ক্ষেত্রে বেশ প্রশস্ত ছিল, যা তার গাণিতিক প্রতিভার কারণ হতে পারে বলে মনে করা হয়। ➕✖️📐 * 💥 তার ডান মোটর স্ট্রিপ (motor strip)-এ একটি বিশেষ স্ফীত অংশ ছিল, যা সাইন অফ ওমেগা (Sign of Omega) নামে পরিচিত। এই বৈশিষ্ট্যটি সাধারণত দক্ষ বেহালাবাদকদের মধ্যে দেখা যায়, যারা তাদের বাম হাতের আঙুল নিপুণভাবে ব্যবহার করেন। আর আইনস্টাইন যে সারাজীবন বেহালা বাজাতে ভালোবাসতেন, তা তো সবারই জানা। 🎻🎶 * 💥 মস্তিষ্কের দুটি গোলার্ধকে সংযোগকারী কর্পাস ক্যালোসাম (corpus callosum) অংশটি ছিল বেশ পুরু। এর ফলে হয়তো তার মস্তিষ্কের উভয় অংশের মধ্যে যোগাযোগ ব্যবস্থা অনেক বেশি শক্তিশালী ছিল। 🔗 * 💥 তার নিউরনগুলোও বেশ ঘন সন্নিবিষ্ট ছিল এবং নিউরন প্রতি গ্লিয়াল কোষের (glial cells) সংখ্যাও ছিল বেশি, যা দ্রুত তথ্য প্রক্রিয়াকরণে সহায়ক হতে পারে। ⚡ তবে এই গবেষণা নিয়ে বিতর্কও কম হয়নি। ⚖️🤔 সমালোচকদের মতে, মাত্র একটি মস্তিষ্ক পরীক্ষা করে কোনো নিশ্চিত সিদ্ধান্তে আসা সম্ভব নয় এবং একে আইনস্টাইনের প্রতিভার একমাত্র কারণ হিসেবে প্রতিষ্ঠা করাটাও অবৈজ্ঞানিক। 🚫 এই চুরির জন্য ডক্টর হার্ভেকে চরম মূল্য দিতে হয়েছিল। 😔 তিনি তার মেডিকেল লাইসেন্স এবং কর্মজীবন—দুটোই হারান। 🚫🧑‍⚕️ অবশেষে, মস্তিষ্কের বেশিরভাগ অংশই প্রিন্সটন মেডিকেল সেন্টারে ফিরিয়ে দেওয়া হয়, যেখানে তা আজও সযত্নে সংরক্ষিত আছে। 🔐 তবে আপনি যদি এই কিংবদন্তী মস্তিষ্কের অংশবিশেষ নিজের চোখে দেখতে চান, তারও সুযোগ রয়েছে। 👀 ফিলাডেলফিয়ার মুটার মিউজিয়াম (Philadelphia Mütter Museum)-এ আইনস্টাইনের মস্তিষ্কের কিছু খণ্ডাংশ আজও প্রদর্শনের জন্য রাখা আছে, যা এক কিংবদন্তী বিজ্ঞানীর মৃত্যুর পরেও তাকে ঘিরে তৈরি হওয়া রহস্যের সাক্ষী হয়ে রয়েছে। 🏛️❓ #Einstein #AlbertEinstein #EinsteinsBrain #Science #Mystery #Genius #History #Neurology #BrainFacts #MutterMuseum #ScientificDiscovery #আইনস্টাইন #আইনস্টাইনেরমস্তিষ্ক #বিজ্ঞান #মস্তিষ্করহস্য #জিনিয়াস #ইতিহাস #নিউরোসায়েন্স #বৈজ্ঞানিকতথ্য #রহস্য

  • While kryptonite may be best known as Superman’s ultimate weakness, its real-world twin, jadarite, could be humanity’s secret weapon in the shift to clean energy. First discovered in Serbia’s Jadar Basin in 2004, jadarite is a rare white mineral made of sodium lithium borosilicate hydroxide—almost chemically identical to the fictional version. Now, scientists at the Natural History Museum in the U.K. have figured out the exact "recipe" for how this rare mineral forms, explaining why it’s only ever been found in one place on Earth.

    Researchers found that jadarite only forms under extremely precise geological conditions—think of it like baking a cake where the temperature, ingredients, and timing have to be just right. For jadarite to crystallize, an unusual combination is needed: an alkaline-rich closed lake, volcanic glass full of lithium, and clay minerals all interacting in perfect harmony. If even one factor is off—too acidic, too cold—it doesn’t form.

    Why does this matter? Jadarite is incredibly rich in lithium, which is crucial for powering electric vehicle batteries and future fusion reactors. The Jadar deposit alone could supply up to 90% of Europe’s lithium needs. By understanding how jadarite forms, scientists now have a guide to look for it elsewhere, potentially unlocking more low-cost, high-efficiency sources of this critical mineral.

    So while kryptonite might weaken Superman, jadarite could help supercharge a greener future for us all.

  • Before Facebook, Mark Zuckerberg launched “Facemash” in 2003 — a controversial website where Harvard students rated each other’s attractiveness. Inspired by "Hot or Not," the platform was quickly taken down for breaching university privacy rules. Yet, this short-lived project laid the foundation for what would become one of the world’s most influential social networks.

    We are ahead of your starting...

  • This video is a full business documentary on Microsoft, Bill Gates, and Paul Allen. It features a lot of archive footage of the early days at microsoft, a lot of old interviews with bill gates, as well as displaying old microsoft products.

    One of my favorite things about making this video was actually going through old microsoft footage and finding the first windows operating system (windows 1.0), the first MS-Dos footage, Windows 95 footage and commercials, etc.

    But ya, this was a pretty full-on business documentary...but because Microsoft is a trillion dollar company with a lot of history, I obviously couldn't get into a lot of topics that i wanted to talk about.

    For example, I wanted to talk about the relationship between Microsoft and Apple a lot more. I wanted to mention Steve Ballmer an Ric Weilands importance to the company. I wanted to talk about what happened to Kent Evans (he unfortunately passed away as a teenager). I wanted to talk about microsofts other investments and their future going ahead with Satya Nadella. I also wanted to dive into bill gates history and biography, but there was just no time for any of that. Most of these could be separate documentaries in themselves.

    This video is about the lakeside computer club. And how a group of teenagers in seattle took over the computer industry, the operating system industry, and the internet browser industry. They also took a giant chunk out of other business fields as well like the gaming industry with xbox and mojang/minecraft, the movie industry with dreamworks, the travel industry with expedia, the social networking industry with linkedin, video calling with skype...etc.
