New cloud-based platform opens genomics data to all

Harnessing the power of genomics to find risk factors for major diseases or search for relatives relies on the costly and time-consuming ability to analyze huge numbers of genomes. Computer scientists have now leveled the playing field by creating a cloud-based platform that grants genomics researchers easy access to one of the world’s largest genomics […] more…

IT security: Computer attacks with laser light

Computer systems that are physically isolated from the outside world (air-gapped) can still be attacked. This is demonstrated by IT security experts. They show that data can be transmitted to light-emitting diodes of regular office devices using a directed laser. With this, attackers can secretly communicate with air-gapped computer systems over distances of several meters. […] more…

Securing data transfers with relativity

The volume of data transferred is constantly increasing, but the absolute security of these exchanges cannot be guaranteed, as shown by cases of hacking frequently reported in the news. To counter hacking, a team has developed a new system based on the concept of ‘zero-knowledge proofs’, the security of which is based on the physical […] more…

Government action needed to ensure insurance against major hacking of driverless vehicles, experts warn

Government action is needed so driverless vehicles can be insured against malicious hacks which could have potentially catastrophic consequences, a study says. more…

Physicists describe photons’ characteristics to protect future quantum computing

Physicists have described in theoretical terms how to develop codes that cannot be broken by quantum computers — computing devices of the future. These codes rely on distributing single photons that share a quantum character solely among the parties that wish to communicate. more…
