Weird science facts that will make you nervous

Do you know that fly larvae helps to heal wounds quicker? Enjoy our amazing science facts as below

Fly larvae helps to heal wounds quicker


Long ago, some doctors noticed soldiers that had maggots on their wounds healed quicker than those without maggots. Maggots eat the dead skin cells and bacteria. Maggot Therapy (also known as Maggot Debridement Therapy (MDT), larval therapy, larva therapy, or larvae therapy) is the intentional introduction of live, disinfected maggots or fly larvae into non-healing skin or soft tissue wounds of a human or other animal. This practice was widely used before the discovery of antibiotics, as it serves to clean the dead tissue within a wound in order to promote healing. 

Animals can naturally explode


Natural animal explosions can occur for a variety of reasons. On 2004, a buildup of gas inside a decomposing sperm whale, measuring 17 meters (56 ft.) long and weighing 50 tons, caused it to burst in Taiwan. The explosion was reported to have splattered blood and whale entrails over surrounding shop-fronts, bystanders, and cars. 

A significant population of toads in Germany and Denmark were exploding in April 2005 in an act described as a self-defence mechanism that failed, as it consisted of puffing up to look bigger while under attack by crows. 

You can still have an erection once dead

A death erection (sometimes referred to as "angel lust") is a post-mortem erection which occurs when a male individual dies vertically or face-down with the cadaver remaining in this position. During life, the pumping of blood by the heart ensures a relatively even distribution around the blood vessels of the human body. Once this mechanism has ended, only the force of gravity acts upon the blood. As with any mass, the blood settles at the lowest point of the body and causes edema or swelling to occur; the discoloration caused by this is called lividity. 

If an individual dies vertically such as in a hanging, the blood will settle in the legs and pool at the feet. The pressure will be greatest as the weight of the blood pushes down. This causes the blood vessels and tissues in the feet to engorge to their greatest elastic capacity and hold the greatest volume of blood possible. This effect occurs right up the legs although to a lesser extent than the feet and is also notable at the waist. The blood which remains in the torso attempts to move to a lower position due to gravity, and as the blood in the waist (which cannot move down due to the legs being full) causes the penis, consisting of erectile tissue, to fill with blood and expand. This is the death erection. As long as the body remains in this position the effect will continue. This is one of the most amazing facts ever.

Male seahorses can get pregnant


Seahorses reproduce in an unusual way: the male becomes pregnant. Pipefishes and seahorses are the only species in the animal kingdom to which the term "male pregnancy" has been applied. 

The male seahorse has a brood pouch in which he carries eggs deposited by the female. The mating pair entwine their tails and the female aligns a long tube called an ovipositor with the male's pouch. The eggs move through the tube into the male's pouch where he then fertilizes them. The embryos develop in ten days to six weeks, depending on species and water conditions. When the male gives birth he pumps his tail until the baby seahorses emerge. 

The male's pouch regulates salinity for the eggs, slowly increasing in the pouch to match the water outside as the eggs mature. Hatched offspring are independent of their parents. Some spend time developing among the ocean plankton. At times, the male seahorse may try to consume some of the previously released offspring. Other species (H. zosterae) immediately begin life as sea-floor inhabitants (benthos). 

A fetus can get trapped inside of its twin


Fetus in fetu (or Foetus in foetu) describes an extremely rare abnormality that involves a fetus getting trapped inside of its twin. It continues to survive as a parasite even past birth by forming an umbilical cord-like structure that leeches its twin's blood supply until it grows so large that it starts to harm the host, at which point doctors usually intervene. Invariably the parasitic fetus is anencephalic (without a brain) and lacks internal organs, and as such is unable to survive on its own, though it may have almost human (albeit underdeveloped and bizarre) features such as limbs, digits, hair, nails and teeth. Fetus in fetu is such a rare condition that only some 91 cases worldwide have ever been reported. Fetus in fetu happens very early in a twin pregnancy, when one fetus wraps around and envelops the other. The dominant fetus grows, while the fetus that would have been its twin lives on throughout the pregnancy, feeding off its host twin like a kind of parasite. Usually, both twins die before birth from the strain of sharing a placenta. Sometimes, however, the host twin survives and is delivered.

Top 17 mind-blowing nervous system facts

Dive in our top 17 mind-blowing and amazing facts about nervous system as following. The nervous system is a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body.


#1

Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system. 

#2

The nervous system is a complex structure of nerves of neurons that transmit signals around the body to coordinate actions. It is in effect our body's electrical wiring. This might be one of the most science facts awesome that had surpprised to us.

#4

The nervous system of vertebrates (which includes humans and animals that have backbones and spinal columns) has two parts, the central nervous system (CNS) and the peripheral nervous system (PNS).

#5

The CNS includes the brain, spinal cord and retina of the eyes. The brain is protected by the skull, and the spinal cord by the skeletal vertebrae.


#6

The PNS includes all other nervous system structures that sit outside the CNS but that help connect the CNS to areas of the body.

#7

Nerves are enclosed bundles of long fibers called axons which are made up of nerve cells. There are two types of nerve cells: neurons and glial cells.

#8

Glial (or glia) cells are derived from the Greek word "glue". They are specialized cells that provide structure and support to neurons. They help hold neurons in place, supply nutrients to neurons, destroy germs, remove dead neurons, and direct axons of neurons.

#9

Some types of glial cells generate a substance called myelin that coat axons and work as electrical insulation to help them quickly and efficiently transmit signals.

#10

Neurons quickly and precisely send signals as electrochemical waves along axons to other cells. There are two types of neurons, sensory neurons and motor neurons.

#11

Sensory neurons change light, touch and sound into neural signals which are sent back to our CNS to help our body understand and react to its surroundings.

#12

Motor neurons transmit neural signals to activate muscles or glands. This is the truth, not only jokes to get relaxing moments.

#13

There are approximately 100 billion neurons in the human brain and 13.5 million neurons in the human spinal chord.





#14

The nervous system can transmit signals at speeds of 100 meters (328 feet) per second.

#15

The field of science that focuses on the study of the nervous system is called neuroscience. Neurology is the medical branch of study and treatment, while doctors and surgeons in this field are called neurologists and neurosurgeons.

#16

Nerves in our body can be vulnerable to both physical damage and damage through diseases. Damage to nerves can cause great pain, loss of feeling, or loss of muscle control.

#17

Physiatrists help rehabilitate patients with nervous system damage.

Top 10 amazing World Series facts

Here are top 10 amazing World Series facts that will challenge your knowledge

1. Championship Game Predates World Series


Prior to the first World Series in 1903 and from 1884-1890, an Exhibition Series occurred between the champions of the National League and the American Association (a rival association that folded in 1891). The event was disorganized and thrown together by the teams themselves. Sometimes the Series lasted three games and others as many as 15. When the American Association dissolved, the National League continued as the only league.

2. Only one “world champion” team didn’t come from the United States

Despite the competition’s all-inclusive name, only one team not based in the United States has won the World Series: the Toronto Blue Jays, victors in both 1992 and 1993. Only one other international team—the now-defunct Montreal Expos—has ever even played in the major leagues, though they never appeared in the Fall Classic. Though there are talks of expanding into Mexico or other nearby countries (travel time makes a truly international sport difficult), an American “world champion” is a virtual guarantee for now.

3. Only One No-Hitter

It is the fact that Yankees’ pitcher Don Larsen recorded the only no-hitter (in this case a perfect game) in World Series history during Game 5 of the 1956 Series.

4. Most Consecutive Scoreless Innings Pitched was 33

With 33 consecutive scoreless innings pitched, Whitey Ford holds the World Series record. Previously, the record holder was Babe Ruth, who pitched 29 2/3.

5. World Series was Cancelled Twice 

The player’s strike in 1994 cancelled that year’s Fall Classic, while a rivalry between the Boston Pilgrims and the New York Giants ended the 1904 Series. During World War II, the Series continued, however many of the best players fought overseas and were missing from the games. In 1943, the New York Yankees won the Series without Hall of Famers Joe DiMaggio, Phil Rizzuto, and Red Ruffing.

6. First Pinch-Hit Home Run was in 1947

Yogi Berra hit the first pinch-hit home run in World Series history in Game 3 of the 1947 World Series against the Dodgers’ pitcher, Ralph Branca. The Yankees lost the game, but won the Series in seven games.

7. Managers with 7 Wins had the Most in a World Series 

Former Yankee managers, Joe McCarthy and Casey Stengel, set the record with each winning seven World Series games during their managerial careers.

8. It’s a Small World


It may be called the World Series, but it doesn’t seem like the rest of the world gets to play. The Toronto Blue Jays are the only team outside the US to have won the World Series – they were back-to-back champions in 1992 and 1993.

9. Most Stolen Bases was in 1967

Super-fast Lou Brock from the Cardinals set the single-season record with seven stolen bases in the 1967 World Series and in 1968 he tied it. He also shares with Eddie Collins the largest number of career stolen bases in the World Series, 14.

10. Before Championship Rings, Players took Home Watches or Medallions

Since 1967, the winner of the World Series has received the Commissioner’s Trophy and traditionally each winning team has presented its members with championship rings. Previously, players were given pocket watches or medallions. In 1922, the New York Giants became the first team to issue rings.

Aboves are the selected facts on World Series from factoflife that can help you know more about this.
