Potholes: How engineers are working to fill in the gaps

Potholes are a perennial problem. They are dangerous to road users, and the damage they cause to vehicles can be hugely expensive. The cost of repairing them is also vast. But still they appear, and reappear, in countless ...

Levitation trick gives drag the slip

Plunging hot spheres into viscous liquids reveals a way to reduce fluid resistance without complex engineering procedures.

DNA sequencing improved by slowing down

EPFL scientists have developed a method that improves the accuracy of DNA sequencing up to a thousand times. The method, which uses nanopores to read individual nucleotides, paves the way for better - and cheaper - DNA sequencing.

Cleaning up behind the fashion industry

A reagent capable of removing colour left in the waste water used in the textile industry is an improvement, but choosing quality dyes would lead to less pollution alltogether.
