This article is about a surprisingly basic question:
What exactly is one second?
Right now the official answer is tied to cesium atoms. But newer optical clocks are now so much more accurate that scientists are seriously considering redefining the second using a better kind of clock.

This article is about one of the hardest periods in cosmic history to study: the time before the first stars and galaxies lit up the universe.
Scientists call the later part of that transition the cosmic dawn. The article explains how a new generation of telescopes and radio experiments may finally let us study that era directly instead of mostly guessing at it.

This article is about a bizarre particle-physics idea called vacuum decay.
The scary version is that if it happened, a bubble could form and spread through space at nearly the speed of light, changing the laws of physics in the region it passed through. Inside that bubble, ordinary matter and life as we know them would no longer work.

This article is about a weird astronomy problem: some tiny galaxies seem to be missing dark matter.
That is a big deal because dark matter is usually treated like the hidden glue of galaxies. Astronomers cannot see it directly, but they usually infer that it is there because stars move as if extra invisible mass is helping hold everything together. So if a galaxy really has little or no dark matter, it is like finding a house still standing after someone removed what everyone thought was one of its main support beams.

This article makes a simple point that is easy to miss when you see flashy astronomy headlines.
Finding the “most distant galaxy ever” is not automatically exciting just because it beats the previous record. If the new galaxy is only a tiny bit farther away than the old one, then the record itself does not teach us much. But if the new record happens because telescopes have made a real leap forward, then it can open a new window into the early universe.

This article says space weather is no longer just an astronomy curiosity. It is becoming a practical business problem.
Solar storms can interfere with GPS-guided tractors, satellites, airline operations and parts of the power grid. Because so much of modern life depends on electronics and precise signals, better forecasts of the sun’s behavior have real value.

Techmeme surfaced this announcement on its April 7, 2026 front page, and the original post is Anthropic expands partnership with Google and Broadcom for multiple gigawatts of next-generation compute.
Anthropic says it signed a new deal with Google and Broadcom for multiple gigawatts of next-generation TPU capacity, with the new compute expected to start coming online in 2027. In the same post, Anthropic says its run-rate revenue has passed \$30 billion, up from about \$9 billion at the end of 2025, and that the number of customers spending more than \$1 million annually has doubled from 500-plus in February to more than 1,000.

This summary covers The Economist’s March 28th, 2026 Business article listed in the contents as A chip-smuggling scandal and headlined on the page as Silicon scandal.
The core idea is simple: America may restrict the sale of top AI chips to China, but that does not mean those chips stop reaching China. The article argues that the real story is not just one alleged smuggling case. It is that export controls are hard to enforce when the supply chain is long, global and full of middlemen.

This summary covers The Economist’s March 28th, 2026 Finance & economics article listed in the contents as War and inflation and headlined on the page as Here we go again.
The core idea is simple: the war with Iran has pushed energy prices sharply higher, and that means the cost of living could start rising again just when many rich countries thought the inflation problem was mostly behind them.

This summary covers The Economist’s March 28th, 2026 Science & technology article on page 76, headlined Picking their brains.
The core idea is that the AI race is not just about chips, money or the best model release. It is also about who has the deepest pool of talented researchers, and the article argues that China is now pulling ahead on that front.
