The Software Company That Bet 8 Years on a Battery: How KPIT Built India's First Indigenous Sodium-Ion Power Pack—and Handed It to a Manufacturer to Take on Lithium

The Five Friends Who Bet Everything on Building the World's First Hybrid Satellite Eye

In 2020, five final-year students at IIT Madras sat in a hostel room and asked themselves a question that most aerospace engineers spend entire careers avoiding. What if you could put two completely different kinds of cameras on the same satellite? Not one optical camera that takes beautiful pictures in daylight and goes blind the moment a cloud passes over. Not one radar sensor that can see through storms and darkness but produces images that look like a grainy ultrasound. Both. On one platform. Working together. The question was technically elegant and commercially insane—the kind of problem that had defeated every satellite manufacturer for a generation because the two sensors interfered with each other, the data streams were incompatible, and the engineering complexity was orders of magnitude greater than building two separate satellites.

America Is About to Have Two Stock Markets for the Same Company: Inside the SEC's $15.1 Billion Tokenized Stock Gamble

Sometime this week, the U.S. Securities and Exchange Commission is expected to publish a document that will do something no American financial regulator has ever done. It will create a legal framework for two parallel stock markets to trade the same shares of Apple, Tesla, and Nvidia—one running on the century-old infrastructure of the New York Stock Exchange, the other on crypto rails that settle instantly, operate 24 hours a day, and require no permission from the companies whose shares they track. The document is called an "innovation exemption," and it is the most significant regulatory experiment in the structure of American equity markets since the creation of the SEC itself in 1934.

The €180 Million Bet That Went Quietly Wrong: Inside the Metacore Meltdown—and Supercell's Gamble to Salvage It

In the autumn of 2020, a small Finnish game studio released a mobile puzzle title that should not have worked. The game involved no shooting, no racing, no combat of any kind. Its central mechanic was merging—dragging one garden tool onto another to create a slightly better garden tool, then using that tool to renovate a crumbling mansion. The protagonist was a grandmother. The story, such as it was, involved a family mystery buried somewhere in the estate. The name, Merge Mansion, sounded like a retirement-home hobby.

The Five-Week Software Upgrade That Could Save Your Next Flight: How a Romanian Startup Is Rewriting the Code That Keeps 10 Million Planes a Year From Colliding

In a modest office in Romania's capital, a team of engineers has spent the past year doing something that the global aviation industry has spent decades trying to avoid: they rewrote the software that coordinates air traffic across an entire continent. Not a prototype. Not a simulation. The actual production software that underpins aviation systems used in airports and air traffic control operations across Europe, contributing to successful journeys for tens of millions of airline passengers every year.

The Payment Rail That Ate India Just Swallowed Greece: How UPI's Silent Global Takeover Is Redrawing the Map of Money

On a quiet Wednesday morning in Athens, a Greek software engineer named Dimitris opened his Eurobank app and sent €200 to his freelance contractor in Bengaluru. The money left his account in euros, converted to rupees at a rate that was near-interbank, and landed in the contractor's Indian bank account approximately twelve seconds later. The fee was 0.07 percent. Dimitris did not need to enter a SWIFT code, an IBAN number, or any of the arcane alphanumeric identifiers that have made cross-border payments a multi-day ordeal for half a century. He typed a UPI ID—a virtual payment address that looks like an email address—and pressed send.

Adapt or Die: Inside the Conference Room Where Michael Dell Told Every Business on Earth That AI Is No Longer Optional

The Battery That Could Eat Lithium's Lunch: Inside the Cambridge Lab Where Sulfur Just Beat Every Chemistry on the Periodic Table

The quest for a better battery has consumed more capital, more scientific talent, and more failed promises than almost any other technology in the modern era. Solid-state lithium-metal batteries. Lithium-air batteries. Sodium-ion batteries. Graphene supercapacitors. Flow batteries. Each has arrived with breathless claims and departed with quiet disappointment, unable to match the relentless, incremental improvement of the lithium-ion cells that power everything from smartphones to electric vehicles to the grid storage facilities that are beginning to replace natural gas peaker plants.

The Handheld Device That Paints New Skin: How a 2-Kilogram Bioprinter Could Make Burn Centers Obsolete

On the third floor of the Stanford University School of Medicine, a team of bioengineers has built a machine that sounds like science fiction and looks like a hot glue gun. It weighs less than 2 kilograms. It fits in a paramedic's backpack. It uses living human cells—fibroblasts, keratinocytes, the building blocks of skin—as its ink. And it prints new skin directly onto wounds, layer by layer, without grafts, without donors, without the painful, scarring, months-long process that has been the standard of care for severe burns and deep wounds since the invention of the skin graft in the 19th century.
