A new “lab-on-a-chip” can examine thousands of individual live cells over a weeklong period, performing experiments that would take more than 1 million steps in a laboratory.

The credit-card-sized, microfluidic device not only saves time and money, but also offers a new glimpse into how single stem cells react to different molecules and environments.

When researchers examined neural stem cells on the device and analyzed the data, they found several new rules that determine the timing and signaling sequences necessary for the cells to differentiate or renew themselves. The finding could have implications in understanding brain development or in treating patients with immunotherapy.

No Homework! Why Finland’s school system is the best in the world

schoolwork

Homework is rarely given until students are teenagers.

Our education system is failing our students. There are also a lot of different options presented on how to ‘fix’ it. Everyone has an answer, a promising new way of thinking, a potential magic bullet. Inevitably, we also examine school systems that are working as a part of investigating what to do or not to do with our own. (Infographic)
