A team of researchers from Microsoft has identified a potential security gap, called a biological zero-day, in the system protecting against biological threats. This system screens DNA purchases for dangerous sequences, but may overlook threats from AI-designed toxins.
Understanding the potential threat
Biological risks can be pathogens, toxins, or harmful chemicals. They all start with DNA, which is transcribed into RNA and then turned into proteins. The ease of ordering DNA sequences online has raised alarms about potential threats in recent years.
To address this, governments and industries have added a screening system for DNA orders. This system checks for sequences that can create harmful proteins or viruses, flagging any suspicious orders for further human review.
The evolution of screening processes
For decades, the scanning process has evolved to keep pace with scientific advancements. Initially, screenings relied on comparing DNA sequences, but variations in DNA that can produce the same protein have prompted updates to the algorithms used.
These updates ensure that all variants capable of encoding threats are recognized, improving the chances of catching dangerous orders before they are fulfilled.
Call for improved safety measures
The emergence of AI-designed proteins introduces new concerns for public safety. As these technologies progress, experts are calling for enhanced safeguards to prevent potential biological threats.
Continued collaboration between the government and industry is essential in adapting to these evolving risks and ensuring the safety of the system.
