Optics: Nanotechnology's benefits brought into focus

Conventional lenses, made of shaped glass, are limited in how precisely they can redirect beams of incoming light and make them meet at a point. Now, a team led by Zhengtong Liu at the A*STAR Institute of High Performance ...

Encryption is less secure than we thought

Information theory—the discipline that gave us digital communication and data compression—also put cryptography on a secure mathematical foundation. Since 1948, when the paper that created information theory first appeared, ...

Microelectronics: Automating cancer detection

Microelectronic engineers in Singapore have developed and tested sensor technology that can detect and measure a chemical signature of bladder cancer. The light-based sensor could eventually be used for the early diagnosis ...

An arms-race with mutual benefits

When you hear the word "mutations", you probably think of something negative like heritable diseases. But mutations also mean genetic diversity and are at the centre of evolution. Researchers have now uncovered a surprisingly ...
