Today’s big topic: Expert: Denmark should consider scrapping personal ID numbers altogether
What’s happening?
A leak affecting 8.8 million people has sparked calls to rethink Denmark’s CPR system and how the state stores sensitive personal data. Prosa chairman Niels Bertelsen says the breach is so serious that Denmark should even consider abolishing the CPR number altogether.
He argues the problem is that one ID number opens the door to a vast range of public records, leaving citizens exposed when systems fail. Both Bertelsen and cybersecurity expert John Foley say it is alarming that such a huge volume of data could be accessed without triggering a response.
They are calling for tighter controls, better monitoring and clearer answers from authorities about how the breach happened. Bertelsen also says responsibility should not be placed on citizens to protect themselves when it is the system that has failed.
Why it matters!
The CPR system is central to daily life in Denmark, linking citizens to healthcare, tax, banking and a wide range of public services. If that data is exposed, it can be used for identity theft, fraud and highly convincing scams, putting millions of people at risk.
The breach also undermines trust in the state’s ability to protect some of the most sensitive information it holds. In a highly digital society like Denmark, that makes it not just a technical failure, but a major societal problem.

Talk of town: Nobel laureates remotely control the brain with algae protein and light
The newly named Nobel laureates have developed a technology that uses light to activate individual nerve cells in the brain and change behaviour in mice — for example, making them run away.
Three researchers have won the Nobel Prize in Medicine for a discovery that sounds like science fiction: using light to control brain cells. Their breakthrough began with a light-sensitive protein found in algae and grew into a technology known as optogenetics.
It allows scientists to switch specific nerve cells on and off and observe how that changes behaviour in living animals. The method has transformed brain research by making it possible to link individual neural circuits to memory, movement and emotion.
Researchers say it is already deepening our understanding of disorders such as PTSD, depression and autism. It may even help pave the way for treatments that restore sight to some blind patients.
