An unidentified signal producing event (USPE) is an event in a nanopore current trace that cannot be attributed to a known particle, molecule or instrument artifact. The term belongs to Molecular Reality Corporation, whose members' help file defines it as "a unique molecular fingerprint or electrical signature generated by an uncharacterized substance passing through the nanopore" and makes cataloguing and identifying USPEs "a primary goal" of the World Particle Project.[1] The phrase is formed like "unidentified flying object", with "signal producing event" where "flying object" would be. In a 2026 post on the names of genomic technology startups, Kemmish put Roswell Biotechnologies among the three best, "(I was sooo jealous of this name!)", with Two Pore Guys and demonpore, inc.[2]
The company's critique of its own machine-learning plans reports what happens when a model flags whatever looks unfamiliar in raw current: it "mostly 'discovers' bubbles, capacitive glitches, and pH drift", for "an effective false-discovery rate near 100%".[3] Of the 12,618 reports of unidentified flying objects that the United States Air Force logged between 1947 and 1969, 701, about 5.6 percent, remained unidentified.[4]
Use
Members of the Molecular Streaming Corps are told by the software's tour that they score "XP and glory for identifying Unidentified Signal Producing Events, contributing confirmed ground-truth data to the World Particle Project".[5] The same help file has Maxine's Mind, the planned central model of the Corps, clustering USPEs from the data that players upload.[1] Company materials script the character Maxine to greet clean data with "Spikes! Sweet, clean translocation blockades!" and the remark "Let's see if my algorithms can cluster these USPEs into a recognizable metabolic fingerprint."[6]
A draft of the company's Disclosure Crawl turns the cataloguing into a collecting game. Players carry a device to local water, soil and their own kitchen counters and play "USPE Pokémon", scoring more for signals that are more unique, under the slogan "Gotta Sense 'Em All!" Its example of a later community challenge is to "Find the source of the 'Mysterious Murmur_XB_734' signal prevalent in the Pacific Northwest!" Its leaderboards were to track, among other things, the "most USPEs discovered in the WPP".[7]
Standard of confirmation
The critique allows a signal to count as a discovery only by consensus: "Discovery requires consensus. A single anomaly is an amplifier glitch. An anomaly that recurs across dozens of different GPS-tagged devices with the same 5-D latent fingerprint is a candidate novel molecule." Agreement across the fleet is meant to control false discoveries, because "cross-device, cross-time reproducibility is the credibility test."[3] The crawl draft ends with a skeptic, written "as requested" to argue against the company, who asks how a genuine USPE is to be told from "a user sneezing near their sample, a power fluctuation, or a contaminated reagent kit", and predicts that a model trained on such data "will be the ultimate exercise in apophenia".[7]
What recorded events usually are
| Event | What the current does | Usual check |
|---|---|---|
| Known particle or molecule | Falls for a time and recovers; the depth tracks the volume of liquid displaced | Depths and durations cluster by sample |
| Folded molecule | A deeper level, about twice that of a single strand[8] | Levels at whole multiples of the single-strand depth |
| Conductive pulse | Rises above the baseline instead of falling, in dilute salt[9] | Sign changes with salt concentration |
| Bubble or poor wetting | Noise that rises, a conductance that comes and goes[10] | Wet the pore again and compare the current-voltage curve |
| Clog | Falls and stays low | Voltage pulse, or opening the pore if it is adjustable |
| Capacitive transient | A spike that decays exponentially after a change of voltage | Appears only when the voltage is changed |
| Baseline drift | A slow wander over seconds to minutes from electrodes, temperature or pH | Present with no sample in the cell |
| Mains pickup | A regular oscillation at 50 or 60 Hz and its multiples | Shielding; vanishes in a grounded enclosure |
| Amplifier glitch | A single sharp excursion | Does not recur |
In the member software the quest for the World Particle Project, worth 1,000 XP, asked in 2026 for samples: "Start curating and collecting samples for molecular streaming experiments. Got freezer space? Get in touch!"[11]
