What Does A Hydrogen Economy Actually Need?
Hydrogen can store energy and replace fossil fuels in some industrial processes, but only if production, transport and storage all work at once. Each of those is a separate unsolved problem.

What Does Battery Recycling Actually Involve?
Recycling lithium-ion batteries is possible and increasingly necessary, but it is closer to chemical processing than to ordinary waste sorting.
-
What Does Carbon Removal Actually Involve?
Removing carbon dioxide that is already in the atmosphere is far harder than reducing emissions. Durability, measurement and scale are the three things that decide whether an approach matters.

What Are Exoplanet Surveys Actually Finding?
Thousands of planets are now known around other stars. The headline result is not other Earths but a startling diversity of worlds, most of them unlike anything in our own solar system.

How Is CRISPR Moving From Editing To Treatment?
Gene editing has moved from a laboratory tool to approved therapies for a few conditions. The hard problems now are delivery, safety and whether editing should be permanent at all.

What Is a Large Language Model?
A large language model is a program trained to predict the next word from the words before it, across enormous text. That single skill, scaled up, produces the fluent answers people now call AI.

What Is an Algorithm, Really?
An algorithm is just a precise, finite set of steps for getting from a problem to an answer. Cooking recipes, sorting rules and search engines are all algorithms; computers simply make them fast.

China’s FAST Telescope Finds the Lightest Known Double Neutron Star
FAST detected PSR J1856-0039, a double neutron star system with the lowest total mass known and an orbit of just 2.36 hours. The find, published in Physical Review Letters, lets astronomers test general relativity in extreme gravity.

A Wave of New AI Flagship Models Landed in September 2026
Across the first half of September 2026 several major labs shipped new flagship models, with a clear split between ever-larger systems and smaller, far more efficient ones. The trend says as much about cost as about capability.

What Is a Neural Network, Really?
A neural network is a huge stack of adjustable numbers arranged in layers, tuned so that feeding in input produces the desired output. The design borrows a metaphor from brains, not the mechanism.
