Organ-on-a-chip mimics heart's biomechanical properties

23/02/2017

The human heart beats more than 2.5 billion times in an average lifetime. Now scientists at Vanderbilt University have created a three-dimensional organ-on-a-chip that can mimic the heart's amazing biomechanical properties.

Artificial synapse for neural networks

22/02/2017

For all the improvements in computer technology over the years, we still struggle to recreate the low-energy, elegant processing of the human brain. Now, researchers at Stanford University and Sandia National Laboratories have made an advance that could help computers mimic one piece of the brain's efficient design - an artificial version of the space over which neurons communicate, a synapse.

Multiregional brain on a chip

16/01/2017

Harvard University researchers have developed a multiregional brain-on-a-chip that models the connectivity between three distinct regions of the brain. The in vitro model was used to extensively characterize the differences between neurons from different regions of the brain and to mimic the system's connectivity.

Wearable sensors can tell when you are getting sick

16/01/2017

Wearable sensors that monitor heart rate, activity, skin temperature and other variables can reveal a lot about what is going on inside a person, including the onset of infection, inflammation and even insulin resistance, according to a study by researchers at the Stanford University School of Medicine.

New type of monitoring: life of bacteria in microdroplets

12/01/2017

In the future, it will be possible to carry out tests of new drugs on bacteria much more efficiently using microfluidic devices, since each of the hundreds and thousands of droplets moving through the microchannels can act as separate incubators.
