Each week, we scour the worlds of innovation, tech for good and social impact to bring you seven of our top stories…

1. Heinz is developing a recyclable paper-based ketchup bottle. The bottle is expected to have a lower carbon footprint than conventional plastic and glass bottles.
2. The Guardian reports that an experimental cancer therapy has shown early promise by shrinking tumours in the digestive system. ‘Car T-Cell therapy’ modifies white blood cells so they can recognise and kill cancerous ones.
3. Science.org reports a new algorithm using gravity signals is in development to detect earthquakes at the speed of light. The speed of the detection will allow safety alerts to be sent out sooner in case of emergency.
4. Hyundai has designed a ‘walking car’ that can move over difficult terrains using mechanical legs that unfold to stabilise the car.
5. Students in DR Congo have created art from discarded flip flops, plastic rings, and radio parts. The pieces are made to raise awareness of topics from pollution to how Western nations have affected the DRC’s development.
6. Scientists believe that brain death may be reversible after proving that dead eyes can still respond to light and communicate with each other up to five hours after death.
7. Supernatural, a virtual reality exercise app, is making exercise more accessible than ever. The app can be adapted to fit a variety of mobility needs, as well as encouraging users who may feel anxious working out in public to exercise without worry.
