Cây cối “ngủ” vào ban đêm như thế nào? 🌿🌙

 Không chỉ con người và động vật, cây cối cũng có nhịp sinh học riêng.

Các nhà khoa học đã dùng camera hồng ngoại để ghi lại và phát hiện:

  • Ban ngày, lá cây vươn lên để đón ánh sáng và quang hợp.

  • Ban đêm, nhiều loài cây hạ thấp lá xuống giống như đang “ngủ”.

  • Thậm chí, nhịp gập mở của hoa cũng gắn với “đồng hồ sinh học” bên trong.


👉 Điều thú vị:

  • Nếu bạn bật đèn suốt đêm trong phòng có cây, cây sẽ bị rối loạn giấc ngủ, giống như con người mất ngủ vậy.

  • Một số nghiên cứu cho thấy cây ngủ đủ giấc thì ban ngày quang hợp tốt hơn, phát triển nhanh hơn.

💡 Vậy nên: đặt cây ở chỗ có chu kỳ sáng – tối tự nhiên cũng giúp cây “khỏe mạnh” hơn.

Cambricon Goes Supersonic: 4,000% Revenue Boom, But Nvidia Still Laughs from Its Throne

 China’s AI chip scene just got spicy. Cambricon, a homegrown chipmaker, pulled off an insane 4,000% revenue jump in the first half of 2025, hitting $402 million with record profits of $143 million. Talk about glow-up energy. Cambricon But let’s keep it real: while Cambricon is celebrating, Nvidia made $46.7 billion in a single quarter . That’s like bringing a water gun to a flamethrower fight. So, what’s going on? The Ban Dance : The U.S. keeps tightening export rules, cutting China off from Nvidia’s best AI chips. Even Nvidia’s “China-only” H20 chip was banned, unbanned, and slapped with a 15% revenue cut for Uncle Sam. Beijing, meanwhile, is telling its tech giants: “Maybe don’t buy that.” The Stock Party : Investors are hyped. Cambricon’s stock more than doubled this year, shooting its market cap to $80 billion . Not bad for an underdog scooter chasing an F1 car. The Reality Check : Nvidia isn’t just about hardware—it owns the AI software playground too. Cambricon ...

🏃‍♀️ The 92-Year-Old Grandma Who Runs 200m in Under a Minute!

 🥇 1. The Speed Queen of U-100 Meet Emma Maria Mazzenga —at 92 years old , she clocked 54.47 seconds in the 200m sprint. That’s fast enough to leave some teenagers gasping for air. Oh, and she basically ran solo : In Italy? She was the only runner. At the World Championships? Just her vs. one American grandma. Legendary. 💪 2. Her “Age-Hacked” Body Scientists are losing their minds over her muscle tissue: Heart health = like a 50-year-old. Fast-twitch fibers = like a 70-year-old. Slow-twitch endurance fibers = like a 20-year-old. Translation: she’s basically a hybrid between Wonder Woman and a Duracell battery. 🔋✨ 🔬 3. Science Can’t Get Enough Italian and American researchers literally drove hours just to beg her for muscle samples (tiny chunks, the size of a pencil eraser). Now, labs are studying her cells and planning three major scientific papers. Yes, grandma is about to become a peer-reviewed superstar . 📚🏅 📊 4. The Grandma’s Sec...

🌍 Google Spills the Tea: Your AI Prompt Isn’t Free (Environmentally Speaking)

  🤖 The Cost of Asking Gemini “What’s 2+2?” Turns out, every time you chat with Google’s AI, the planet pays a tiny bill . According to Google’s latest report, a single Gemini prompt costs: ⚡ 0.24 Wh of energy → about 9 seconds of Netflix 🍿 💧 0.26 ml of water → basically five baby drops 🌫 0.033 g CO₂ → like riding a scooter for 1 km… after 1,000 prompts 🛵 So yes, your dumb “write me a haiku about pizza” request does leave a microscopic footprint. 💪 Google’s Eco Glow-Up Before you clutch your metal straws, Google wants you to know: it’s getting better. ⚡ Energy efficiency: 33x improvement in one year 🌱 Carbon reduction: 44x cleaner Basically, Gemini went from gas-guzzler to Prius… okay, maybe not a Tesla yet. 🚗⚡ 🌊 The “Tiny x Billions” Problem Here’s the kicker: while each query is small, we’re all addicted. Multiply those baby water drops by millions of users and—oops—suddenly it’s Niagara Falls. 🌊 And by 2030, AI could slurp down more el...

🌲🌿 Brooo… They Found a Whole Weed Forest in California! 🌿🌲

 magine hiking in Sequoia National Park thinking you’ll see squirrels and big trees. Then suddenly—BAM 💥—you walk into a 13-acre marijuana jungle . Like Narnia, but instead of a lion, it’s just… leaves that make you giggle. The Numbers That’ll Blow Your Mind 🤯 2,377 marijuana plants = enough to make Snoop Dogg say “Woah, that’s a lot.” Each plant drinks 30 liters of water per day . That’s more than me on a hot day after 3 bowls of pho. Rangers also found a gun and illegal pesticides . Dude… this ain’t chill, that’s just shady.

Có nên đầu tư vàng thời điểm này?

 Trong bối cảnh kinh tế thế giới nhiều biến động, vàng luôn được xem là một trong những kênh trú ẩn an toàn. 1. Ưu điểm khi đầu tư vàng Bảo toàn giá trị: Vàng thường giữ giá trị tốt trong thời kỳ lạm phát. Thanh khoản cao: Dễ dàng mua bán tại các tiệm vàng hoặc ngân hàng. Ít rủi ro hơn so với chứng khoán, forex. 2. Nhược điểm khi đầu tư vàng Lợi nhuận không cao: Vàng tăng giá khá chậm so với bất động sản hoặc chứng khoán. Biến động ngắn hạn: Giá vàng có thể lên xuống theo tin tức, chính sách tiền tệ. Chi phí mua bán: Chênh lệch mua – bán (spread) có thể khá cao, nhất là vàng SJC. 3. Lời khuyên cho nhà đầu tư cá nhân Nên dành 10 – 20% tài sản cho vàng như một kênh phòng thủ. Nếu vốn nhỏ, có thể mua tích lũy từng chỉ. Tránh “lướt sóng” vàng nếu không có nhiều kinh nghiệm. 👉 Tóm lại: Vàng phù hợp để giữ giá trị lâu dài , nhưng không nên kỳ vọng “giàu nhanh” từ vàng.

👕 From Trendy Tee to Dinner Plate: The Wild Journey of Microfiber Fashion

  🌀 Laundry Day: When Shirts Go Rogue Your shiny new polyester T-shirt looks cute… until laundry day.

🌦️ La Niña Might Crash This Fall… But Don’t Freak Out

  The Forecast: Scientists say there’s a 21% chance La Niña will show up between July and September 2025, and over 50% from September to January 2026. Translation: she might come by, but she’s probably just dropping in for a coffee. ☕ Who is La Niña Anyway? La Niña is basically El Niño’s chilly cousin . She loves global weather chaos: ❄️ Northern U.S.: cold & wet 🌞 Southern U.S.: warm & dry 🌪️ Atlantic: hurricane playground But Don’t Panic: Experts say this La Niña is likely a lightweight . Think of her as the guest who eats your snacks but doesn’t touch your Wi-Fi—annoying, but harmless. Meanwhile… Earth is still heating up thanks to climate change, so whether ENSO decides to throw a tantrum or not, it’s still getting toastier out there. 🔥 Bottom Line: La Niña might swing by, but she’s shy, short-term, and won’t ruin your life. Stay cozy, enjoy your cocoa, and maybe keep an umbrella handy. ☔
