35 Amazing and Interesting Facts about Guinea Pig | Amazing Facts 4U

The guinea pig was domesticated as early as 5000 B.C. in South America as a source of food. They were also used in religious ceremonies and in traditional medicine. They have been kept in households as companion animals since being introduced by European traders in the 16th century.
The scientific name of the guinea pig is Cavia porcellus, which means “little pig.” They belong to the family Caviidae, which is a family of South American rodents. They are also not from Guinea; they originated in the Andes.
Guinea pigs may have been called pigs for several reasons. For example, they have a similar squeal to a pig’s. They are also somewhat built like a small pig, with a large head, stout neck, and no real tail.
While guinea pigs are not from Guinea, it is possible “guinea” was included in their name because they may have been sold for a guinea (English coin). Another theory is that Europeans may have believed guinea pigs came from the African country Guinea since ships carrying the furry mammals from South America often stopped there before going on to Europe.
Male guinea pigs are called boars, females are referred to as sows, and young ones are called pups.
If a female guinea pig is uninterested in a male during courtship, she will sometimes squirt a jet of urine at the persistent male.
The gestation period of a guinea pig is about 70 days. A female guinea pig (called a sow) is able to produce a litter of up to 4 young guinea pig pups.
The amazing fact is that if a female guinea pig does not give birth before she is 6 months old, her pubic bones will fuse. If she tries to give birth later, the fused bones will prevent her from giving birth resulting in the death of the mother and the unborn pups.
Guinea pigs have a high maternal mortality rate of about 20%.
Baby guinea pigs are born with their eyes open and are covered in fur. Baby pups are able to drink from a water bottle and can eat hay within hours of being born. They can run only 3 hours after being born.
Guinea pigs in fact have 3 toes on their forefeet and 4 toes on their hind feet.
Guinea pigs have a long and detailed history of being used in medical research from the 17th century. While rats and mice have become more popular test animals in the modern era, guinea pigs are still used as subjects for juvenile diabetes, tuberculosis, scurvy, and pregnancy complications.
There are two general categories of guinea pigs: long-haired and short-haired. Short-haired guinea pigs are typically easier to care for than long-haired ones.
Guinea pigs typically live about 4 or 5 years, though they may live up to 8. The longest-living guinea pig on record was Snowball from Nottinghamshire, England. She died at the age of nearly 15 years in February 1979.
Guinea pigs don’t have to sleep for long periods. They prefer to take short naps throughout the day and night.
Guinea pig ears are very sensitive to noise and they do not like any loud bangs.
Guinea pigs can hear sounds of up to 40,000 to 50,000 Hz, and some guinea pig vocalizations are ultrasonic at above 20,000 Hz.
Guinea pigs are particularly vocal. They have a range of vocalizations to communicate with each other, including ‘purring’ when content and ‘chirping’ when stressed.
Guinea pigs can’t sweat like humans can and so can get heatstroke if they are left out in the sun or become too hot. They have to find shade whenever possible.
Guinea pigs have what is known as “open rooted” teeth like rats which constantly grow to require them to constantly grind down their teeth while eating food keeping them properly aligned.
Guinea pigs will eat all day and night.
They do not bite in self-defense and will only bite because they think your hand is food.
Guinea pigs have a very good field of vision and are able to see around them so as to detect predators. The amazing fact is that they can’t see anything straight in front of their noses which means they don’t see what they eat.
The American guinea pig is one of the oldest breeds of guinea pigs and is considered the “classic guinea pig.” One of the most commonly found, it is an ideal pet for children because of its short, smooth fur.
Guinea pigs typically run a higher temperature than humans, at about 101° F. Their high temperature places them at increased risk on hot days or when they’re exposed to direct sunlight.
After about 4 years old, guinea pigs are usually considered senior citizens, and genetic health issues usually appear at this time.
Guinea pigs are very social and are truly happy only when they are together with other guinea pigs. Even the most loving human cannot take the place of other guinea pigs.
Because guinea pigs are so social, it is illegal to own just one in Switzerland.
When you are holding a guinea pig, the way to settle it down if it’s wriggling too much is to bring your hand under its back-side and amazingly it will stop wriggling.
A recent study found that children ages 5 to 12 on the autism spectrum showed a marked decrease in stress while interacting with guinea pigs. The pet could act as a “social buffer” for students with autism who may have difficulty making friends.
Guinea pigs are fragile creatures and so need to be treated with gentle hands. If you are rough, you could break its bones. In fact, they have a total of 258 bones in the body.
Amazingly guinea pigs always march in single file, with the largest guinea pig at the front and the young protected in the middle.
Guinea pigs have been found to be allergic to penicillin.
Guinea Pigs have excellent spatial orientation and are able to learn complex maze tasks using symbols as signposts.
Like humans, guinea pigs are unable to make vitamin C and need to acquire it through food sources. Failing to do so can lead to scurvy and eventually death.

Tears

Amazing Facts 4 U — Thu, 26 Mar 2026 09:30:00 +0000

20 Amazing and Interesting Facts about Tears | Amazing Facts 4U

Everyone starts life with that first cry. As you grow up, you still produce about 200 ml of tears a day, even if you never or rarely cry.
Although babies have the same instinct to cry to satisfy their needs, each culture’s socialization processes lead to different ways of crying as an older child or adult.
The film of tears on the eye is a complex system, in fact consisting of three layers of oil, water, and mucus. The water layer is the thickest and contains electrolytes like sodium and potassium, proteins (mostly enzymes), glucose, and other substances. Various facts in the outer oil layer slow evaporation.
The specific composition of tears may change day today.
The lacrimal glands that secrete tears are located on the outer portion of the upper eyes. They are peanut-sized. blinking spreads the tears across the eye surface. Tears drain into the tiny openings in the eyelids, called puncta (one on the inside corner of each lid), and then through ducts to the nasal cavity, where you either swallow them or they become part of nasal fluid.
Besides lubricating the eye and flushing away debris, tears also serve the function of delivering oxygen and nutrients and removing waste products. Tears also improve the image that forms on the retina by smoothing any irregularities on the surface of the eyeball.
Tears also serve as a defense mechanism. The antibodies, enzymes, and other immune components in tear help protect the eyes against microorganisms.
There are three types of tears. Continuous (or basal) tears are produced for basic eye function, such as lubrication. Reflex (or irritant) tears occur when the eye is exposed to excessive light, the cold, wind, a foreign body, or irritating food like cut onions. Psychogenic tears are shed for emotional reasons.
Crying is a way to communicate needs and elicit attention from others, at least in early life, and maybe a means of releasing emotional tension. As per research, psychogenic tears differ in composition from other tears, and crying may be a way to rid the body of stress-related chemicals.
Boys and girls cry in equal frequency. Women reportedly cry more than men.
When a person cries and the first drop of tears comes from the right eye, it’s happiness. But when the first tears come from the left, it’s pain.
Emotional tears actually contain leucine encephalin, a natural painkiller.
A baby who cries for more than 3 hours a day, more than 3 days a week, for more than 3 weeks may have abdominal colic.
The ducts that drain tears from your eyes can become blocked due to aging, infection, inflammation, injury, tumor, or cyst causing symptoms of excessive tearing and watery eyes.
In certain neurological conditions, crying along with laughing can be uncontrolled. The condition is called pathological laughing and crying (PLC). Laughter or sobbing can occur at inappropriate times. PLC can appear as a symptom of stroke, Alzheimer’s disease, multiple sclerosis, and amyotrophic lateral sclerosis(ALS).
All vertebrates i.e. animals with backbones that spend time on land have continuous tears and perhaps reflex tears. Humans are the only animals that also have emotional tears. There are also reports of elephants shedding tears in grief.
Syn-propanediol-S-oxide is the chemical released by onions in the air which irritates the eyes making lacrimal glands release more tears. New Zealand researchers have been able to produce tearless onions by inhibiting the gene that makes this chemical.
If tear production declines or tears evaporate too quickly, the result is dry eye. Inflammation may play a role. Besides causing burning or grittiness, dry eye syndrome can cause blurry vision and can potentially damage the eye.
Tears have the same composition as saliva made up of proteins, salt, and hormones.
A woman’s tears amazingly send a particular chemical signal to men which causes a dip in male sexual arousal, which is an involuntary yet interesting means of nonverbal communication between the sexes.

Radiation

Amazing Facts 4 U — Fri, 20 Mar 2026 09:30:07 +0000

30 Amazing and Interesting Facts about Radiation | Amazing Facts 4U

Radiation is the energy that comes from a source and travels through space. When this energy passes into the body, either by penetrating skin or being swallowed or inhaled, it may be harmful. Whether the radiation is ionizing or non-ionizing will influence the health risks.
Sources of ionizing radiation include nuclear weapons handling and detonation, nuclear plants, x-rays, etc.
Non-iodizing radiation is low-energy radiation that includes radiation from sources such as sunlight, microwaves, radio frequencies, radar, and sonar.
Radium, a radioactive element was discovered by Marie Curie who in fact died from radiation exposure.
Millirem is 1/1000 REM, a unit to measure radiation.
The loss in life expectancy from a 1 millirem dose is about 1.2 minutes, equivalent to crossing the street three times, taking three puffs on a cigarette, 10 extra Calories for an overweight person.
Nuclear power plants are very safe. In fact, the safety limit for exposure is just 5 millirem.
The average radiation exposure due to medical diagnostic procedures is about 80 millirem per year.
People in America living near coal-fired power stations are exposed to higher radiation doses than those living near nuclear power plants.
Chest X-ray gives off about 30 millirems of radiation.
The average person absorbs about 300 millirems of radiation per year in total from background sources.
1% of static on an untuned analog TV is from cosmic background radiation from the Big Bang.
The thorium-rich sands of Kerala, India give off 380 millirems per year, and similar sands in Guarapari, Brazil give locals an amazing 600 millirems per year.
Residents of Denver, Colorado get about four times as much cosmic radiation as those in who live at sea level, giving them an extra 115 millirems of radiation per year.
The Manhattan Project secretly tested the effects of radiation on its own citizens, including injecting pregnant women with radioactive mixtures and feeding children radioactive oatmeal. In the end, about 1,400 children died due to these experiments.
During the Manhattan Project, a man was injected with Plutonium without his knowledge or consent and he survived it for 20 years, eventually surviving the highest radiation dose known for any human.
Bananas are slightly radioactive and eating a banana exposes a person to radiation.
Because of the amount of granite used in its construction, the Grand Central Station of New York City produces more radiation than what is allowable at a nuclear power plant.
Astronauts on the Apollo missions reported seeing flashes and streaks of light when they closed their eyes. This was later confirmed to be caused by cosmic radiation bombarding their retinas while outside of the Earth’s magnetosphere.
All the American flags placed on the moon are now white due to radiation from the sun.
In the 1950s, there was a toy called the Gilbert U-238 Atomic Energy Laboratory that came equipped with low-level radiation sources and four Uranium-bearing ore samples. It sold for $49.50. The product stayed on the market for only about a year between 1950 and 1951.
The Chernobyl Nuclear Power Plant disaster was huge. It is still giving off radiation, and that there is a high chance of the containment structure collapsing, causing huge amounts of radiation to spread out.
A fireman’s eyes at the Chernobyl disaster are said to have turned from brown to blue because of the intensity of the radiation he received.
There is a type fungi inside the Chernobyl reactors that thrives on radiation.
Flight crews are classified as radiation workers and some are exposed to more radiation annually than nuclear plant workers. One flight from New York to London is equivalent to one chest X-ray.
Smokers receive a radiation dose equivalent to about 300 chest x-rays annually due to the radioactive isotope Polonium-210 contained in tobacco smoke that comes from the ingredients of the fertilizers that are used in farming tobacco.
The USA originally denied that atomic bombs caused lingering radioactivity, calling such claims Japanese propaganda
A handful of raw uranium ore actually only has about as much radiation as 10 bananas. Banana has radiation due to potassium content.
The use of nuclear weapons and testing has resulted in steel contaminated with background radiation in many areas after 1945 making it unusable for many scientific and medical applications and steel made before 1945, often taken from sunken battleships, must be used instead.
On December 27, 2004, Earth was hit by the largest blast of radiation in recorded history. It came from a “giant flare” on a magnetar 50,000 light-years away.

Breast Cancer

Amazing Facts 4 U — Sat, 14 Mar 2026 09:30:53 +0000

30 Amazing and Interesting Facts about Breast Cancer | Amazing Facts 4U

The first recorded mastectomy for breast occurred in A.D. 548 on Theodora, Empress of Byzantine.
Breast cancer was one of the first cancers to be described by ancient physicians. For example, physicians in ancient Egypt described breast cancer more than 3,500 years ago. One surgeon describes “bulging” tumours in the breast of which “there is no cure.”
In 400 B.C., Hippocrates describe breast cancer as a humoral disease caused by black bile or melancholia. He labelled cancer karkinos, meaning “crab,” because the tumours seemed to have tentacles which looked like the legs of crab.
The first operation to use anaesthesia was a breast cancer surgery.
Breast cancer is the most common type of cancer among American women after skin cancer. It is the second leading cause of cancer death in women after lung cancer.
The incidence of breast cancer is highest in more developed countries and lowest in less developed countries.
The left breast is statistically more prone to developing cancer than the right breast. Reason is not known.
In the U.S., on average one woman die of breast cancer every 15 minutes. The United States has the most cases of breast cancer in the world.
Only 5-10% of breast cancers occur in women who have a genetic predisposition for it.
Nearly 10.4 % of all cancers in women is breast cancer.
Approximately 1.2 million cases of breast cancer are diagnosed around the world each year. About 75% are found in women over age 50.
When breast cancer spreads beyond the breast, it is said to be “metastatic.” The most common places breast cancer spreads to are the bones, liver, and lungs.
There are currently 2.5 million breast cancer survivors living in the United States.
Usually 95% of new cases and 97% of breast cancer deaths occurred in women 40 years and older. The biggest single risk factor for breast cancer is age.
White women have a higher incidence of breast cancer than African American women. However, African American women are more likely to die from breast cancer than white women.
About 1 in 3,000 pregnant or lactating women will develop breast cancer. Research has shown that once a woman has been diagnosed with breast cancer during pregnancy, her chances of survival are less than a non-pregnant woman.
Mammography was initially used in 1969 when the first specialized X-ray units for breast imagining were developed.
Women age 40 and older should have screening mammograms every 1 to 2 years. It is estimated that if every woman over the age of 50 had her yearly mammogram, breast cancer deaths in this age group would drop by 25% or more.
Tumors are more likely to be malignant when they are firm and have irregular shapes, while benign tumors are more likely to feel round or soft. On average, it takes 100 days or more for a cancer cell to double in size. It takes about 10 years for cells to divide to a size that can be actually felt.
Breast cancer in men is rare, accounting for approximately 1% of breast cancer rates. African American men are more likely to die from breast cancer than white men.
One in 40 women of Ashkenazi (French, German, and East European) Jewish descent carry the BRCA1 and BRCA2 (breast cancer) gene, which is significantly higher than in the general population where only 1 in 500 to 800 people carry the gene.
In 1882, the father of American surgery, William Steward Halstead (1852-1922), introduced the first radical mastectomy (the breast tissue underlying chest muscle and the lymph nodes are removed). Until the mid 1970s, 90% of women with breast cancer were treated with this procedure.
The youngest known survivor of breast cancer is Aleisha Hunter from Ontario, Canada. At only three years old, Aleisha underwent a complete mastectomy in 2010 to treat her juvenile strain of breast cancer.
Breastfeeding has consistently been shown to reduce breast cancer, the greater the duration, the greater the benefit.
No association has been found between breast implants and an increased risk of breast cancer.
The most common type of breast cancer (70%) originates in the breast ducts and is known as ductal carcinoma. A less common type of breast cancer (15%) is known as lobular carcinoma or cancer that originates in the lobules. More rare types of cancers include medullary carcinoma, Paget’s disease and tubular carcinoma.
Research has found that pomegranates may help prevent breast cancer. Chemicals called ellagitannins block the production of estrogen, which can fuel some types of breast cancer.
Studies report that breast cancer patients with diabetes were nearly 50% more likely to die than those who didn’t have diabetes.
October is National Breast Cancer Awareness Month (NBCAM). The first NBCAM took place in October 1985.
Not all lumps that are found in the breast are cancerous but may be a fibrocystic breast condition, which is benign.

Diabetes

Amazing Facts 4 U — Sun, 14 Dec 2025 09:30:02 +0000

50 Amazing and Interesting Facts about Diabetes | Amazing Facts 4U

The word “diabetes” is Greek for “siphon,” which refers to the copious urine of uncontrolled diabetes. “Mellitus” is Latin for “honey” or “sweet,” a name added when physicians discovered that the urine from people with diabetes is sweet with glucose.
The name “diabetes” is attributed to the famed Greek physician Aretaeus of Cappadocia who practiced in the first century A.D. He believed that diabetes was caused by snakebite.
The earliest recorded mention of a disease that can be recognized as diabetes is found in the Ebers papyrus (1500 B.C).
William Cullen (1710-1790), a professor of chemistry and medicine in Scotland, is responsible for adding the term “Mellitus” (“sweet” or “honey-like”) to the word diabetes.
About one-third of all people with diabetes do not know they have the disease. Type 2 diabetes often does not have any symptoms.
Diabetes mellitus is a general name that encompasses several types of diabetes, including Type 1, Type 2, gestational, and variations such as maturity-onset diabetes in the young (MODY) and latent autoimmune diabetes of adulthood (LADA). What they all have in common is the inability to self-regulate levels of blood glucose (cellular fuel) in the body.
A normal fasting (no food for 8 hours) blood sugar level is between 70 and 100 mg/dL. A normal blood sugar level two hours after eating is less than 140 mg/dL.
Diabetes is diagnosed by 2 consecutive fasting blood glucose tests that are equal to or greater than 125 mg/dL OR any random blood glucose that is greater than 200 mg/dL OR an A1c test that is equal to or greater than 6.5 percent. A1c is a blood test that gives a three-month average of blood sugars OR A two-hour oral glucose tolerance test with any value over 200 mg/dL.
Prediabetes indicates you carry a risk to develop diabetes. It is diagnosed by any one of the following: A fasting blood glucose in between 100-125 mg/dL OR an A1c between 5.7 – 6.4 percent OR any value between 140 mg/dL and 200 mg/dL during a two-hour oral glucose tolerance test.
In 1889, Oskar Minkowski (1858-191931) discovered the link between diabetes and the pancreas when a dog from which he removed the pancreas developed diabetes.
Insulin was coined from the Latin insula (“island”) because the hormone is secreted by the Islets of Langerhans in the pancreas.
Before the discovery of insulin, surgeons rarely operated on diabetic patients with gangrene because the patients typically would not heal and would inevitably die.
Insulin was first isolated at the University of Toronto by a team led by scientist Frederick Banting from Ox in 1921. They then went on to give insulin to dozens of dying children and stood back to watch the miracles. The following year, Banting was granted the Nobel Prize in Medicine.
Banting and his team could have potentially made billions from insulin discovery but they chose to sell the patent to the University of Toronto for just half a dollar.
Initially, the insulin was extracted from the pancreas of a cow (bovine) or pig (porcine). Today’s insulins are created in the lab, cultured from bacteria and yeast through recombinant DNA.
Before the discovery of insulin, physicians would often put their patients on starvation or semi-starvation diets, recommending they eat only foods such as oatmeal.
In 1942, the first oral type 2 diabetes medication was identified, a sulfonylurea.
Obesity has led to a dramatic increase in Type 2 diabetes. Approximately 90% of people with Type 2 diabetes are found to be obese. Excess abdominal fat, is a risk factor for Type 2 diabetes.
Overweight individuals are more prone to develop diabetes because more fat requires more insulin, fat cells release free fatty acids which interfere with glucose metabolism, and overweight people have fewer available insulin receptors.
Smoking can increase diabetes risk by constricting blood vessels, raising blood pressure, and stimulating the release of catecholamines (fight-or-flight hormones), which promote insulin resistance.
Gestational diabetes occurs in about 200,000 or 7% of U.S. pregnancies annually.
Diabetes in the United States alone costs $200 billion annually. This figure includes direct medical costs, such as insulin, amputations, and hospitalizations as well as indirect costs, such as lost productivity, early retirement, and disability.
Some researchers have found links between the onset of Type 1 diabetes and the contracting of a virus, especially the mumps or Coxsackie virus.
African-Americans and Hispanics have a much higher rate of Type 2 diabetes than whites. There are 74 cases per 1,000 for African-Americans, 61 cases for Hispanics, and 36 cases for whites. Approximately one in three African-American women between the ages of 65-74 have diabetes.
Diabetes in Asians is five times the rate of the white population. Those with severe diabetes run the risk of slipping into diabetic coma either due to very high blood sugar (hyperglycemia) or too low blood sugar (hypoglycemia).
One of the worst complication of diabetes is diabetic neuropathy, which is damage to the blood vessels that supply the nerves presenting itself as a numb, painful, tingling sensation, particularly in the feet. Often, diabetics have peripheral arterial disease which restricts blood-flow to the feet. The skin becomes dry and sensitive, and is more likely to develop ulcers. The lack of circulation makes infection difficult to fight off and even with prompt medical treatment, amputation is often necessary.
Diabetes is the main cause of blindness in individuals aged 20-75 . Early detection and treatment could prevent up to 90% of cases of blindness that are related to diabetes.
Approximately 11% of all Americans aged 65-74 have diabetes. About 20% of those over 75 years old have diabetes, and nearly half of them are unaware they have the disease.
Approximately 25 million U.S. residents have been diagnosed with diabetes, which is nearly 10% of the estimated 250 million people suffering from diabetes worldwide. Only about five percent of all people with diabetes have type 1 diabetes.
Men with diabetes are at a greater risk for erectile dysfunction (ED) than non-diabetic men. Approximately 50-60% of men with diabetes over the age of 50 have problems with ED. Additionally, ED becomes a problem for diabetic men about 10 to 15 years earlier than a non-diabetic man.
Those with diabetes are more likely to develop carpal tunnel syndrome and tarsal tunnel syndrome.
Individuals with diabetes are at much greater risk for developing Alzheimer’s disease and other forms of dementia than are non-diabetics, though the reasons are unknown.
Individuals with diabetes are more susceptible to complications of flu and pneumonia and are six times more likely to be hospitalized for these problems than non-diabetics.
Experts believe that diabetes decreases life expectancy by five to 10 years.
Men have a higher risk of death from diabetes than women.
Research has found that babies who breastfeed at least three months had a lower incidence of Type 1 diabetes and may be less likely to become obese as adults.
Women with diabetes are more likely to develop vaginal infections than are non-diabetics because of their elevated glucose levels.
Diabetics have a higher risk of gingivitis than non-diabetics, which may lead to bone and tooth loss.
Diabetes has been reported in horses, ferrets, and ground squirrels. In environments where animals are liberally fed, diabetes has been reported in dolphins, foxes, and even a hippopotamus.
Inhaled insulin is an emerging twenty-first century option for people with Type 1 diabetes. Companies are also working on an insulin tablet that can be given under the tongue.
The soluble fiber in oatmeal helps control blood glucose levels.
The human body is equipped with 60,000 miles of blood vessels and wired with 100,000 miles of nerve fibers. Diabetes often blocks the cardiovascular system and deadens nerves, causing 80% of deaths among patients with diabetes.
India is the diabetes capital of the world with over 40 million people with diabetes. By 2025, this number is expected to swell to 70 million, meaning every fifth diabetic in the world would be Indian.
Diabetes causes 6 deaths every minute and one in 20 deaths in the world is due to the condition. Every year it is estimated that 3.5 million people in the world die due to the diabetes or its related causes.
Diabetes is responsible for over one million amputations each year, a large percentage of cataracts, and at least 5% of blindness worldwide.
44% of all kidney failure cases are caused by diabetes nephropathy.
Certain diseases such as cystic fibrosis, pancreatitis, hemochromatosis, and Cushing’s syndrome may cause pancreatic beta cell destruction that leads to diabetes.
The five countries with the highest percentage of diabetes are Nauru, United Arab Emirates, Saudi Arabia, Bahrain, and Kuwait.
In 1969, Ames Diagnostics came up with the first portable blood glucose meter called the Ames Reflectance Meter (ARM). Ames later became a part of Bayer.
Diabetes insipidus (water diabetes) is a condition completely different from diabetes mellitus characterized by a problem with the kidneys in which the kidneys are unable to concentrate urine adequately due to a deficiency in the antidiuretic hormone (ADH).
