Carbon capture technology explained: can it actually save us?
Direct air capture can pull CO2 from the atmosphere, but at $100 to $600 per tonne and with global capacity under 0.04% of annual emissions. Carbon capture is a necessary climate tool, but not a substitute for cutting emissions.

Researchers say they are close to reversing aging: the science explained
Senescent cells, Yamanaka factors, senolytics, and NAD+ supplementation — the biology of aging is being mapped and targeted. Animal studies show age reversal is possible. The question is whether it translates to humans.
The danger of predictive algorithms in criminal justice
Risk scores and predictive-policing systems promise consistency, but data shaped by unequal enforcement can turn historical bias into automated decisions.

When antibiotics don't work: the superbug crisis explained
Antibiotic resistance turns ordinary infections into harder, costlier medical problems. Here is how superbugs emerge, why the pipeline is thin, and what alternatives can help.
Why geothermal could be the energy breakthrough everyone agrees on
Geothermal power can deliver electricity around the clock, and new drilling techniques are widening its geography. The opportunity is large, but geology, cost, water, and permitting still matter.
What the physics of sound teaches us about the world
The physics of sound offers broader lessons about invisible causation, the role of the medium, scale-dependent perception, the difference between connection and transport, and the relational nature of reality.
The physics of sound explained: the ideas that matter
The physics of sound rests on a few powerful ideas: vibration as origin, the medium as carrier, frequency as identity, amplitude as intensity, superposition as interaction, and Fourier decomposition as the key to complexity.
The engineering challenge behind the physics of sound
Acoustic engineering means controlling something invisible: sound diffracts around barriers, rooms resonate whether you want them or not, and each additional decibel of noise reduction costs exponentially more in materials and mass.
The hidden history of the physics of sound
The physics of sound did not begin with equations: ancient builders shaped acoustic spaces by trial, Pythagoras heard number in strings, and centuries of corrections from Galileo to Laplace to Helmholtz turned intuition into measurement.
How the physics of sound works
Sound is a mechanical wave that travels through matter by compressing and rarefying it: vibrations push neighboring particles, energy propagates outward, and frequency and amplitude determine what we hear.
What stellar nurseries teaches us about the world
Stellar nurseries teach broader lessons about the world: environments shape objects, small components can control systems, order can emerge, feedback changes outcomes, and the present preserves traces of a long material history.
Stellar nurseries explained: the ideas that matter
The ideas that matter in stellar nurseries are connected steps: cold gas becomes gravitationally unstable, fragments into cores, builds disks and protostars, ignites fusion, and feeds back on the remaining cloud.
The engineering challenge behind stellar nurseries
The engineering challenge of stellar nurseries is to model gravity, turbulence, magnetic fields, rotation, and stellar feedback as one coupled system across enormous ranges of scale and density.
The hidden history of stellar nurseries
Stellar nurseries carry a hidden history in their chemistry, dust, isotopes, and motions. Earlier stars enriched the gas, changed its cooling behavior, and supplied the ingredients for both new stars and planets.
How stellar nurseries works
Stellar nurseries work through gravitational instability in cold molecular clouds: external triggers compress the gas, it fragments into clumps, each clump collapses into a protostar with a disk, and hydrogen fusion begins when the core…
What the circular economy teaches us about the world
The circular economy offers broader lessons about systems, design, and interdependence: waste is a design choice rather than a law of nature, nature has no concept of waste, linear thinking carries hidden costs, and scale changes what is…
The circular economy explained: the ideas that matter
The circular economy rests on a handful of core ideas: the butterfly diagram separating biological and technical cycles, a value preservation hierarchy that prefers repair over recycling, systems thinking over reductionism, and the…
The engineering challenge behind the circular economy
The circular economy is simple in principle but hard in practice: separating joined materials fights entropy, contamination degrades recycled streams, and tracking substances through global supply chains requires infrastructure that barely…
The hidden history of the circular economy
The circular economy feels like a modern invention, but its roots stretch from preindustrial reuse and Kenneth Boulding's 1966 spaceship Earth to the Pearce report, cradle-to-cradle, and the Ellen MacArthur Foundation's butterfly diagram.
How the circular economy works
The circular economy replaces take-make-waste with a system designed to eliminate waste and regenerate nature: biological and technical materials cycle through closed loops, products are designed for disassembly, and business models shift…
