Friday Squid Blogging: Neon Flying Squid on 21/08/2026
The neon flying squid can fly in formation. The shoal of about 100 squid rose unexpectedly from a patch of the Pacific Ocean around 370 miles from Tokyo and glided near the boat for about 30 metres. The astonished researchers were the first to capture photographs of such a thing, which looked like the early stages of an alien invasion. They were probably neon flying squid (Ommastrephes bartramii), [...]
AI Is Learning to Write Genetic Code on 21/08/2026
This sort of research is both exciting and terrifying: The two models in question were told to generate complete genomes for a viable bacteriophage—a type of virus able to infect and replicate itself inside bacteria, destroying them from the inside.

Web fuzzing for hackers by Ayoub and Orwa Atyat on 20/08/2026
Fuzzing has been around for as long as web applications have. In fact, the term itself was coined back in 1988, when Barton Miller, a professor at the University of Wisconsin, was working over a dial-up connection during a thunderstorm and noticed that the resulting line noise was consistently crashing the UNIX utilities he was running. Web fuzzing is no different. Despite the rise of automated sc [...]

How Trail of Bits helps verify the integrity of your Signal chats on 11/08/2026
Every Signal chat starts the same way: the client asks the Signal server for the public key associated with your contact’s phone number. But how do you know the server gave you the right key? A compromised server could provide a false public key, allowing the client to encrypt messages to an attacker rather than the intended recipient. Until now, the only way to detect such malfeasance was to veri [...]
