Bệnh tim mạch giết chết 200.000 người Việt mỗi năm

Tử vong do tim mạch vẫn giữ vị trí số một toàn cầu, cao hơn cả ung thư, riêng Việt Nam mỗi năm có khoảng 200.000 người chết vì nguyên nhân này.

Tháng 1-2026, Việt Nam đón gần 2,1 triệu lượt khách quốc tế — cao nhất 18 năm qua.

 


Trong tháng 1, Việt Nam đón gần 2,1 triệu lượt khách quốc tế — cao nhất từng ghi nhận theo tháng từ trước đến nay, vượt cả mức của tháng 1/2019 và tháng 1/2020 trước đại dịch.
Con số này tăng gần 19% so với tháng trước và khoảng 37% so với cùng kỳ năm trước, với thị trường Trung Quốc đứng đầu về lượng khách gửi đến Việt Nam trong tháng đầu năm.

The Bitter Brew of Revolution: When Coffee Was a Crime !
In the mid-1600s, a new substance arrived in Europe that threatened the very foundations of the monarchy: coffee. Before its arrival, the average European drank beer or wine from morning until night, keeping the population in a permanent state of mild intoxication. Coffee changed everything. For the first time, people were gathering to drink a stimulant that made them sharp, alert, and—most dangerously for kings—talkative. These "Penny Universities," where a cup of coffee cost just one cent, became the breeding grounds for radical ideas and political dissent.
The most famous crackdown occurred in 1675, when King Charles II of England issued a royal proclamation to ban all coffeehouses. He was emotionally overwhelmed by the "great spread of false, malitious and scandalous reports" being whispered over steaming mugs. He feared that these venues were schools of sedition where men plotted to overthrow the crown. The ban, however, was a spectacular failure. The public outcry was so intense and the love for the "bitter invention of Satan" so deep that the King was forced to retract the ban just 11 days later.

Treaty of Breda. Signed after the Second Anglo-Dutch War, this agreement confirmed that Suriname would remain in Dutch hands

 



In 1667 AD, diplomacy followed cannon fire, and the Dutch Republic secured a lasting overseas legacy through the Treaty of Breda. Signed after the Second Anglo-Dutch War, this agreement confirmed that Suriname would remain in Dutch hands — a decision that would shape the history of the Atlantic world for centuries to come.
The treaty came in the wake of dramatic Dutch victories, including the Raid on Chatham led by Michiel de Ruyter, which forced England to negotiate. Under the political leadership of Johan de Witt, the Republic entered peace talks from a position of strength. The result was a settlement in which colonial possessions were formally recognized and exchanged.
What many people don’t realize is that this treaty helped define the global balance between England and the Netherlands: the Dutch kept Suriname, while England held on to New Netherland, including New Amsterdam — now New York. Another striking fact is that Suriname would become one of the most important Dutch colonies in the Americas, deeply tied to plantation economies and the complex, painful history of slavery and colonial rule.
This moment mattered because it showed how the Dutch Golden Age was not only fought on European seas, but also negotiated across oceans. The Treaty of Breda confirmed the Republic’s global reach — and left a legacy that continues to shape Dutch and Caribbean history today.
If you had lived in 1667, would you have seen Suriname as a symbol of Dutch power overseas… or the beginning of a complicated colonial chapter?

Finland is pushing the boundaries of energy transmission by developing wireless electricity systems that send power through the air without physical cables.

 


Finland is pushing the boundaries of energy transmission by developing wireless electricity systems that send power through the air without physical cables. While wireless power itself isn’t new, Finnish researchers are advancing it beyond phone chargers — aiming for room-scale and infrastructure-level applications that could reshape how electricity is delivered.
The technology relies on electromagnetic fields and resonant coupling, allowing energy to move efficiently between a transmitter and receiver without direct contact. Unlike traditional induction charging that works only over millimeters, newer systems can transmit power across several meters with controlled direction and minimal loss.
Engineers envision applications in factories, hospitals, and smart cities where devices, sensors, and robots can operate continuously without plugs or exposed wiring. This reduces fire risk, wear and tear, and maintenance costs, especially in harsh environments where cables degrade quickly.
Safety is a core focus. Power levels are carefully regulated to stay within international exposure standards, ensuring no harm to humans or animals passing through the field. Researchers stress this is not uncontrolled energy in the air, but precisely managed transmission zones.
If scaled successfully, wireless power could transform infrastructure — from charging electric vehicles while parked, to powering sensors in remote locations. Finland’s work shows that the future of electricity may look less like wires and poles, and more like invisible energy woven into everyday space.

Australia is racing across the globe, moving north by seven centimeters annually as the world’s fastest-drifting continent.

 


Australia is racing across the globe, moving north by seven centimeters annually as the world’s fastest-drifting continent.
Australia is currently the fastest-moving continent on Earth, drifting northward at a remarkable rate of approximately seven centimeters—or about 2.7 inches—every year. This rapid journey is fueled by the relentless movement of tectonic plates deep beneath the planet’s crust. While this shift remains imperceptible to those standing on the ground, it represents a significant geological phenomenon that underscores the constant, dynamic transformation of our world.
This steady migration is more than just a scientific curiosity; it has real-world consequences for global navigation and positioning systems. Because the continent’s coordinates change over time, scientists and cartographers must periodically update global maps to ensure precision for everything from GPS technology to aviation. Australia’s constant motion serves as a powerful reminder that the Earth’s surface is never truly still, shifting the very foundations of our geography with every passing year.

Ngôi sao nhanh nhất Dải Ngân Hà: sao lùn trắng J0927, đang lao qua không gian với tốc độ hơn 8,2 triệu km/giờ đủ nhanh để thoát hẳn khỏi lực hấp dẫn của thiên hà.

 


Ngôi sao nhanh nhất Dải Ngân Hà
Các nhà thiên văn học Harvard vừa phát hiện ngôi sao chạy trốn nhanh nhất từng được biết đến trong Dải Ngân Hà.
Đó là sao lùn trắng J0927, đang lao qua không gian với tốc độ hơn 8,2 triệu km/giờ đủ nhanh để thoát hẳn khỏi lực hấp dẫn của thiên hà.
J0927 không cô đơn. Nó bay cùng 3 ngôi sao siêu tốc khác, tất cả đều là tàn dư của một vụ nổ siêu tân tinh cực hiếm và cực mạnh gọi là siêu tân tinh loại Ia dạng D6.
💥 Chuyện gì đã xảy ra?
Hai sao lùn trắng quay quanh nhau. Một ngôi sao “ăn cắp” vật chất của ngôi kia, gây ra phản ứng nhiệt hạch dữ dội, thổi tung một ngôi sao và bắn ngôi còn lại đi như viên đạn vũ trụ.
🔭 Dựa trên dữ liệu từ dự án Gaia (bản đồ sao chi tiết nhất từng có), nhóm nghiên cứu xác nhận J0927 là nhanh nhất từng được ghi nhận, vượt kỷ lục cũ gần 300.000 km/giờ.
✨ Phát hiện này cho thấy siêu tân tinh D6 có thể chiếm tới một nửa số vụ nổ loại Ia, nhưng các nhà khoa học vẫn đang tiếp tục săn tìm thêm những “kẻ đào tẩu” ngoài không gian.
👉 Một ngôi sao… bị thổi bay khỏi chính thiên hà của mình. Vũ trụ đúng là không bao giờ nhàm chán. 🌠
