All Stories by Davide Castelvecchi
- Math
Net advantage
When damaged, networks that seem resilient can still become inefficient to the point of being unusable.
- Tech
Bucky shrink-wrap
Scientists filmed cage-shaped carbon molecules as they shrank to become buckyballs.
- Physics
Shadow World
Physicists have found new evidence for a 10-year-old conjecture that bridges the gap between the many-dimensional space of string theory and more familiar theorizing.
- Tech
Hooking up
Cleverly designed molecules can self-assemble into networks and stay robustly connected.
- Physics
Rock, paper, toxins
A computer model simulates a kind of rock-paper-scissors competition among three species of virtual bacteria.
- Physics
Let There Be Aluminum-42: Experiment creates surprise isotope
In experiments that created the heaviest isotope yet of magnesium, an unexpected isotope of aluminum also showed up.
- Physics
Axion Gone: New tests find no sign of anomalous particle
New experiments contradict earlier claims of the discovery of the axion, a possible constituent of cosmic dark matter.
- Materials Science
Feet of clay, but superstrong
Gluing together nanoscale clay particles with a simple adhesive creates a strong but flexible material.
- Chemistry
Platinumfree fuel cell
Cheaper than a typical hydrogen fuel cell, a new, platinumfree cell runs on a "green" liquid fuel.
- Humans
Mice, Magnetism, and Reactions on Solids
The 2007 Nobel prizes in the sciences recognized research in genetics, materials science, and surface chemistry.
- Physics
Light does some weird math
Adding a photon to a light pulse then taking one out gives a different result from doing the same operations the other way around.
- Earth
A different spin
A change in the properties of Earth's mantle at high pressure and temperature may influence seismic waves in a novel way.
