The line between a planet and star remains blurry, but it just shifted upwards.

Observing the interstellar visitor after its closest approach, astronomers found that its composition appears to have changed.

April 16, 2026:We updated this guide with the Season 3 Dark Ops challenges. What are the BO7 Dark Ops challenges? Dark Ops challenges are tough, hidden missions that only reveal themselves once complete, rewarding you with exclusive Calling Cards to show off your expertise across Zombies, multiplayer, and the new co-op campaign. To save yourself the headache of finding all of these objectives, we've listed all the Black Ops 7 Dark Ops challenges here so you can go straight in with your objective in mind. Many of these are tough, so make sure you've got your favorite BO7 weapons equipped, perhaps even a BO7 Wonder Weapon for the BO7 Zombies Dark Ops quests.

Cats possess a specialised structure known as the vomeronasal organ (Jacobsons organ), located behind the upper incisors and involved in detecting chemical signals. While more commonly associated with the Flehmen response, subtle tongue positioning may accompany these processes.In summary: Sometimes, the blep is not a mistake.It is science at work.Applied Blep Science: The Licky Treat EffectImage Credit: Kirsti HarefalletNo scientific inquiry would be complete without experimental validation. Through repeated, highly motivated trials, I have identified a reliable method of inducing blep-like behaviour: Introduce a licky treat.These semi-liquid, highly palatable substances trigger:rapid, repetitive licking (activation of motor pattern generators)heightened focus and sensory engagementoccasional momentary pauses between licksIt is within these micro-pauses that one may observe partial tongue extension, delayed retraction, and, in optimal conditionsa transient blep-like state.It must be clarified that this is not always a true blep in the classical relaxed sense, but rather a blep-adjacent phenomenon induced by a high-value stimulus. In practical terms, the cat is too invested to manage their tongue properly.Comparative Analysis: The Canine QuestionIt is frequently asked whether dogs, too, engage in blepping. The answer is: Yes, but with notable differences. In both cats and dogs, tongue protrusion may occur during relaxed states. However, the underlying contributors differ in frequency and context.Cats:Commonly linked to relaxation and interrupted grooming motor patternsTypically presents as a small, static tongue tipDogs:May occur during relaxation, but more often associated with dental structure or missing teeth, jaw conformation, and brachycephalic anatomy (e.g., shorter muzzles)More importantly, tongue protrusion is frequently associated with thermoregulation via panting, wherein evaporative cooling occurs across the tongue and oral surfaces, a function distinct from the relaxed or interrupted motor patterns typically observed in feline blepsTongue protrusion in dogs is often more sustained and less tied to grooming behaviourIn popular culture, a distinction has emerged:Term:Typical Use:BlepSmall, subtle tongue tip (commonly cats, sometimes dogs)MlemLarger, active tongue movement (commonly in dogs)It must be emphasised that these terms are informal descriptors, not scientific classifications.Cultural Significance: The Rise of Tongue Out TuesdayIn recent years, the blep has achieved widespread recognition through the weekly observance known as #TongueOutTuesday. While I cannot confirm its precise origin, it has become a global platform for documenting and celebrating instances of lingual protrusion across species. While the weekly ritual of #TongueOutTuesday has its merits, the blep does not operate on a schedule. Perhaps it is time to elevate our standards to: Tongue Out Every Day T.O.-Day.ConclusionThe blep, while seemingly trivial, represents a fascinating intersection of neuromuscular relaxation, behavioural interruption, and sensory processing. It is, in essence, a moment where biology pauses and charm takes over.Final RemarksShould you observe a blep in your domestic environment, I advise the following:Do not panic. Do not correct the cat. Take a photograph immediately. For science, of course.With academic rigor and minimal supervision,Professor FluffovichFeline Behavioural ScientistChair of the Institute for Advanced Blep Studies
