Keeping the structure of the internet safe

The Internet Society has created a way of checking how new regulations could harm the structure of the internet. As the internet doesn’t respect borders, what happens in one country can impact the internet in another. The internet can sustain one or two attacks but many at the same time could even bring it down. Until now there has been no way of predicting how such changes could affect the internet’s architecture. The new toolkit also identifies the critical properties that must be protected to enable the Internet to reach its full potential. EEG that works with Black African American hair Measuring brain activity can be done using Electroencephalograms, or EEGs. These rely on a number of electrodes being attached to the scalp and the tests are used to diagnose diseases like epilepsy. However if the electrodes are not attached to the scalp properly then getting accurate readings is very hard. This is a problem for people with thick and very curly hair – with some patients having to shave their hair for the test. Now Arnelle Etienne, a student at Carnegie Mellon University in Pittsburgh, has designed electrodes that suit her hair type – she is African American and hopes her design will significantly improve test results for patients like her.Buddy PKGE – tech to monitor animal vital signs Harrison Lewis reports on a device capable of measuring animal vital signs that is being adapted to save human lives. The non-invasive tech could help sniffer dogs find people following natural disasters, alerting the handler as soon as dog detects a human heartbeat.The programme is presenter by Gareth Mitchell with expert commentary from Ghislaine Boddington.(Image: Getty Images) Studio Manager: Sarah Hockley Producer: Ania Lichtarowicz
