When a receptor binds to its target molecule, it initiates an internal cascade of protein messengers that directs the cell to activate a genetic program. Receptor proteins on the cell surface comprise the first layer in signal-relays that control whether a cell grows, divides, specializes, or dies. In fact, nearly every type of cell utilizes extracellular instructions. Among other outcomes, these signals lead to bone growth, wound healing, and programmed cell death. Signals from outside the cell control many intracellular programs, even directing how cells develop into organs and whole organisms. Researchers in Germany recently reported on how the cell reads and responds to these directions.
It doesn't get any easier without an actual telephone or instant messenger, and sadly that's not going to be an option on your descent into madness in Bloober Team's Layers of Fear 2.Long before Samuel Morse put his telegraphic code to work, neurons and other cells were processing extracellular dash- and dot-type signals into instructions for cellular decisions. It just became the go-to distress signal often used at sea, likely because of the ease with which listeners can identify the message. The acronym actually isn't an acronym at all. Many say it's "save our ship" or "save our souls" - the latter would be rather fitting in Layers of Fear 2. In reality, though, it actually means. If achievement and trophy hunting isn't enough for you, consider this bonus riddle: what does S.O.S. It's a Bronze level trophy on PS4, while on Xbox One it'll boost your Gamerscore by another 30 points.
The game seems to be relatively forgiving with how you spell out the message and so long as it can identify you know what you're doing, you should complete the Easter egg and unlock your achievement or trophy. If you're new to Morse code, one dash equals about three dots. That's dot-dot-dot for S, dash-dash-dash for O, and dot-dot-dot again. What to enter at the TelegraphĮither in Act I or Act V, if you're looking at the telegraph, you'll need to enter the Morse code for S.O.S. toward the end of the game.įor this Easter egg, you'll only need to enter the correct morse code message in either instance, not both. If you leave the comms room having done nothing, look for the same room to reappear, albeit with some. If the same happens to you, know two things: The door shut behind me and I assumed I had missed a bit of optional content. This Morse code message left behind didn't seem to help me much, as I fidgeted with the telegraph for a good five to six minutes trying to duplicate the code I read on the paper before I finally left not knowing what to do. There's also a print out on the desk which can be interacted with. Inside will be a communications center including a working telegraph on the table. You're not missing much if you skip over it, but it's an easy achievement/trophy and will teach you a bit of life-saving Morse code - and who knows when you may need that? Where is the Telegraph?Īs you're exploring the ship early in the game's first act, you'll come across a room on your left in a well-lit hallway. If you're staring at the telegraph wondering what to do, fear not. One of the first instances of such a puzzle is the telegraph in Act I, and it's even seen again in Act V.
