Physics
We summarize the week's scientific breakthroughs every Thursday.
- Materials Science
Nanotubes: Knot just for miniature work
A new technique can spin individual nanotubes into durable ribbons and threads visible to the naked eye.
- Materials Science
A hard new material with a soft touch
Adding exotic substances called quasicrystals to polymers creates nonabrasive hard materials, which could soon serve as coatings in machine parts.
- Materials Science
New lithium battery design charges up
Researchers have developed a new, safer type of electrode for lithium batteries.
- Physics
When all is a spin, calm is dragged in
When laboratory vortices are mixed to create the equivalent of a tornado in a hurricane, the "hurricane" may gobble up spots of calm from the outside world.
- Physics
Hot little levers write beaucoup bits
Arrays of microscopic tips may offer a way to pack digital data more tightly and transfer it more quickly than is possible with magnetic hard disks.
- Physics
Particle hunt off, collider comes down
Despite tantalizing, last-minute hints of a long-sought, mass-giving particle called the Higgs boson, dismantling of the Large Electron-Positron collider has begun.
- Materials Science
Making Stuff Last
Chemistry and materials science step up to preserve history, old and new.
- Materials Science
Anyone want to knit a microscopic sweater?
Microscopic polymer tubes can tangle themselves into a new and possibly useful structure—tiny "yarn balls" that flatten out and partly unravel in an electric field.
- Physics
An electron ruler gauges crystal flaws
Electrons ricocheting through a crystal now make it possible for scientists to discern shifts in crystal lattices as small as a hundredth of an atom's width.
- Materials Science
One-Upping Nature’s Materials
Striving for designer substances that build themselves from individual molecules.
- Materials Science
To make bronze, tin flakes do a wild dance
Upsetting some prevailing ideas about how alloys form, rafts of tin atoms jitterbug madly around on a pure copper surface and leave spots of bronze in their wakes.
- Physics
Signs of mass-giving particle get stronger
The promising search at a collider in Switzerland for the Higgs boson—the crucial and last undetected fundamental particle predicted by the central theory of particle physics—became even more of a cliff-hanger as a new, strong hint of the particle appeared on the eve of the machine's second scheduled demise.
