We summarize the week's scientific breakthroughs every Thursday.
- Physics
Crueltyfree: Counting photons without killing them
A delicate quantum measurement counts photons without destroying them.
- Physics
Frizzed molecular carpets
Measurements of the speed with which heat travels along single hydrocarbon molecules could aid in the design of molecular electronics.
- Physics
Road Bumps: Why dirt roads develop a washboard surface
Experiments and a computer simulation show why dirt roads develop a washboard surface, and indicate the only way to prevent it: Drive very slowly.
- Materials Science
Shocking Sheets: Power paper packs a punch
Ultrathin sheets made from cellulose and carbon nanotubes could serve as flexible, versatile batteries.
- Physics
Newton’s Dusty Mirror: Old experiment inspires ultrafast imaging
An experiment devised by Isaac Newton inspires a modern successor, in which X rays capture the image of a microscopic explosion.
- Materials Science
Pliable carbon
The layers of carbon atoms that form graphite can be assembled into strong but flexible "graphene paper."

- Materials Science
Gecko adhesive gets added mussel
A new adhesive that borrows tricks from the gecko and the mussel can stick and detach repeatedly and works even when wet.
- Physics
Slick serpent
Oil poured into a pan of the same liquid drags along a surrounding air layer, which can make it skip in and out of the surface before it mixes in.
- Materials Science
Sop Story: New porous gel soaks up heavy metal
A new porous gel efficiently removes mercury from contaminated water and may also have the ability to catalyze chemical reactions such as those that generate hydrogen for fuel.
- Materials Science
Crystal matchmaker
Nonperiodic structures called quasicrystals can act as interfaces between different crystal structures that would ordinarily not stick to each other.
- Physics
The Power of Induction
A new technology based on classical electromagnetic theory uses oscillating magnetic fields to transfer electric power wirelessly across a room.
