The infamous Bermuda Triangle, spanning between Miami, Bermuda, and Puerto Rico, is considered by many to be a hot spot for unexplained disappearances of both ships and aircraft since at least 1840. However, despite extensive research, the reasons behind the vanishings remain elusive. Some attribute the apparent phenomenon to magnetic anomalies, while others point to human error or natural explanations.

Dating back to the 15th century, the Voynich Manuscript is a handwritten book filled with bizarre illustrations and an unknown script referred to as Voynichese. Scholars and cryptographers have attempted to decipher its contents for centuries, yet its mysterious language remains uncracked. While some believe it was conceived as a work of fiction or, perhaps, a joke, the manuscript's true origin, purpose, and the meaning of its intricate drawings remain one of history's greatest linguistic conundrums.

In 1977, a radio signal was detected from deep space by Ohio State University's radio telescope. The strange signal lasted 72 seconds and was dubbed the "Wow! Signal" because it bore the expected hallmarks of extraterrestrial origin. But despite numerous attempts, scientists have still been unable to trace its source or explain its origin. The signal's sudden appearance and unique frequency continue to fuel speculation about life beyond the Earth.

The prehistoric monument of Stonehenge, an imposing circle of colossal stones in the middle of a grassy field, has puzzled archaeologists for centuries. The purpose of its construction as well as the exact technology used by its ancient builders - who did not leave written records behind - remain mostly an enigma. However, many researchers have pointed out that the monument could have functioned as a sort of early astronomical observatory.

In 1948, an unidentified man was found peacefully dead on Somerton Beach in Australia. Police found a scrap of paper that read Tamam Shud (meaning "finished" in Persian) in his pocket, later found to be a torn page from Rubaiyat of Omar Khayyam, a 12th-century Persian poetry book. The man's identity, cause of death, and the meaning behind the mysterious phrase remain unknown to this day. A baffling case that could have easily been ripped off the pages of an Agatha Christie book, The Somerton Man continues to mystify investigators, spawning numerous theories but offering no concrete answers.

In 1959, a group of experienced hikers in the Ural Mountains (then part of the Soviet Union) met a mysterious and tragic end. Their tent was found slashed open, and the hikers were scattered in various states of undress, some with internal injuries. The cause of their deaths and the strange circumstances leading to the incident remain unsolved, with the prevailing secrecy of Soviet authorities at the time further complicating inquiries. The tragic incident has sparked numerous theories, from natural disasters to military experiments, but definitive answers remain elusive.

Residents of Taos, New Mexico, have reported a persistent low-frequency hum, known as the "Taos Hum," since the early 1990s. Despite investigations, the source of this mysterious sound, which can only be heard by a small percentage of the population, remains unknown. Similar phenomena have been reported in other parts of the world, leading researchers to believe local sources or even biological auditory effects might be the cause.

In 1872, the ship Mary Celeste was discovered adrift in the Atlantic Ocean with its crew mysteriously missing. Surprisingly, the ship was intact, with all its food and valuables untouched. Insurance fraud, mutiny, waterspouts, and giant squid attacks have all been proposed as possible explanations, but no convincing evidence was found to prove any of these theories. Despite exhaustive investigations, the fate of the crew and the reason for their sudden disappearance remain one of maritime history's most enduring enigmas.

During the early 20th century, a mysterious illness known as Encephalitis lethargica struck half a million people around the world, causing affected individuals to enter a prolonged state of lethargy or sleep. While the exact cause remains unknown, one of the leading theories suggests that brain inflammation triggered by an autoimmune response to a certain strain of bacteria or viral infection could have been responsible for the observed symptoms.

Hospital secrets

What is a "Code Gray" and what you should know if you hear it at the E.R.

A trip to the emergency room can be stressful enough without hearing doctors and nurses speak a language that sounds like a secret code. One minute, someone is asking for medication "STAT," the next there’s a "Code Gray," and another patient is suddenly "NPO." What do those words really mean? Some are official medical terms, others are insider slang, but they all help hospital staff communicate quickly when every second counts. Here are 10 of those codes explained.

The E.R. can be hectic and unpredictable. Most patients are frightened or uncomfortable, but now and then someone becomes aggressive because of pain, confusion, mental illness, or the effects of alcohol or other substances. That’s when you can hear "Code Gray" announced over the speakers.

The code is used to summon security officers to help manage a violent or combative situation. While color codes vary from one hospital to another, Code Gray commonly signals that staff needs extra assistance to protect patients, visitors, and healthcare workers. Even if you know it now, most people in the waiting room never know what happened, and that’s exactly the point.

You have a scheduled surgery, you’re in your bed waiting to be taken to the surgery room, and you ask for a cup of coffee to make the wait lighter. The nurse will probably tell you you’re an NPO. You may think it’s serious, but it’s simply a procedure.

"NPO" is an abbreviation that comes from the Latin phrase Nil Per Os, which means "nothing by mouth." It tells patients they cannot eat, drink, or sometimes even take medication until doctors say it’s safe. The rule is most common before surgery or certain medical tests, when food or liquids could increase the risk of complications or alter the results. It may be frustrating, but it’s an important part of keeping patients safe.

You’ve probably been through the experience of visiting an emergency room, either to get checked or to visit a loved one. In that part of the hospital where everyone is rushing to save lives, you’ve probably heard a doctor asking for the R.C.P. cart or medication "STAT!" It sounds urgent, and that's because it is.

The expression comes from the Latin statim, which means "immediately" or "without delay." Hospitals have used Latin medical terms for centuries, but STAT is one of the few that remains part of everyday conversation. When a doctor says it, the request jumps to the top of the priority list. It doesn’t always refer to a life-or-death situation, but it does mean the medical team needs something done as quickly as possible.

Newborns are always a reason to celebrate at the hospital. Parents usually rest happily next to their child as they receive congratulations from close relatives. However, the hospital is always prepared to handle extremely rare emergencies under "code pink."

If you hear a "Code Pink," it usually means a baby or young child is suspected of being abducted from the hospital. Within seconds, security officers respond, exits may be monitored or blocked, and staff begins following carefully rehearsed procedures. Although different hospitals sometimes use different color codes, Code Pink has become widely recognized across North America as one of the most serious alerts a hospital can issue.

If you’ve ever spent a few days in the hospital, you’ve probably noticed that some patients are walking up and down the halls, while others need help just getting out of bed. When a nurse refers to someone as a "walkie-talkie," it’s actually good news.

This informal expression refers to patients who can walk on their own, use the bathroom without assistance, and handle most basic tasks independently. It’s not an official medical term, of course, but it’s commonly used among healthcare workers because it quickly tells the next shift that the patient requires less hands-on care than many others.

As nurses change shifts, you’ll often hear them give a quick report about each patient. One person may only need medication, while another is described as a "total."

The term is short for a patient who requires total care. They may need help eating, bathing, getting dressed, turning in bed, or moving from one place to another. Although the expression sounds impersonal, it’s simply a practical way for caregivers to communicate how much assistance someone needs.

Most people hear "frequent flyer" and think of an airline reward program. And that’s correct, but in an emergency room, the phrase has a very different meaning.

A frequent flyer is an informal nickname for patients who repeatedly return to the hospital, often due to chronic illness, recurring medical conditions, or other ongoing health issues. Behind the light-hearted nickname is often a difficult reality. Many of these patients are simply dealing with medical problems that require regular emergency care, and the expression is just a way to make the experience a bit lighter among the familiar faces of doctors and nurses.

Not all codes are for patients. The next time you’re in a hospital, look closely at what the nurse is pushing from room to room. It may look like a small rolling desk with a computer on top. Staff often call it a "WOW," short for "workstation on wheels."

As hospitals switched from paper charts to electronic medical records, these mobile computers became essential. Nurses use them to review test results, scan medications, update patient charts, and check doctors’ orders without leaving the bedside. The name sounds funny, but the technology helps caregivers spend more time with patients instead of walking back and forth to a nursing station.

After getting a shot or having blood drawn, most patients never think about where the used needle ends up. It certainly doesn't go into an ordinary trash can.

Hospitals place needles, scalpels, and other sharp medical instruments into special containers designed to prevent accidental injuries. These sturdy, puncture-resistant boxes are sealed when full and safely disposed of in accordance with strict health regulations. This not only protects nurses, but it also protects cleaning crews, waste handlers, and even the public from dangerous needle sticks. It’s one of the most important safety measures in every hospital, even though most patients never notice it.

If you’ve ever watched a medical drama, you've probably seen a patient become so agitated that several staff members rush into the room. In situations like that, a doctor or nurse may ask for a "B-52." But the name has nothing to do with numbers themselves; it actually comes from a medicine.

B-52 is hospital slang for a fast-acting injection used to calm down patients who are severely combative or at risk of harming themselves or others. The nickname comes from a commonly used combination of medications that usually include diphenhydramine, haloperidol, and lorazepam. It’s strictly reserved for when other methods of calming the patient haven’t worked.
