Heart cells display a behavior-guiding 'nanosense' on new lab-on-a-chip

Johns Hopkins biomedical engineers, working with colleagues in Korea, have produced a laboratory chip with nanoscopic grooves and ridges capable of growing cardiac tissue that more closely resembles natural heart muscle. Surprisingly, heart cells cultured in this way used a 'nanosense' to collect instructions for growth and function solely from the physical patterns on the nanotextured chip and did not require any special chemical cues to steer the tissue development in distinct ways.

New Centre for Molecular Epidemiology to put bacteria on the world map

In future, it will be possible to quickly analyse DNA from pathogenic bacteria via an online so-lution which at same time collects and shows information on species, strains and antimicrobial resistance on web-based world maps. This can contribute to reduce and prevent the global spread of contagious diseases. These are among the perspectives behind the Centre for Molecular Epidemiology which can now be established at Technical University of Denmark.

First measurement of cancer biomarkers in whole blood

A team led by Yale University researchers has used nanosensors to measure cancer biomarkers in whole blood for the first time. Their findings could dramatically simplify the way physicians test for biomarkers of cancer and other diseases.
