DNA mutations get harder to hide

Rice University researchers have developed a method to detect rare DNA mutations with an approach hundreds of times more powerful than current methods.

Use your smartphone for biosensing

An Australian research team has shown that smartphones can be reconfigured as cost-effective, portable bioanalytical devices, with details reported in the latest edition of the Open Access Journal 'Sensors'.

Faster, portable microbial analysis in the field

Until recently, it took hours – sometimes days – to analyze biological samples after they were frozen in the field and brought back to the laboratory. But now there is a faster, cheaper and smaller way ...

Toward 'green' paper-thin, flexible electronics

The rapid evolution of gadgets has brought us an impressive array of "smart" products from phones to tablets, and now watches and glasses. But they still haven't broken free from their rigid form.

Light-emitting fork made with sprayed LEC technology

Light-emitting electrochemical cells, LEC, is a newly invented lighting technology. In his thesis, physicist Amir Asadpoordarvish, Umeå University, shows how a LEC can be produced through spraying three ...

What happens inside a membrane
