10 Microscopic Images Inside the Human Body

Almost all of the following images were captured using a scanning electron microscope (SEM), a type of electron microscope that uses a beam of high-energy electrons to scan surfaces of images. The electron beam of the SEM interacts with atoms near or at the surface of the sample to be viewed, resulting in a very high-resolution, 3D-image. Magnification levels range from x 25 (about the same as a hand lens) to about x 250,000. Incredible details of 1 to 5 nm in size can be detected.
Max Knoll was the first person to create an SEM image of silicone steel in 1935; over the next 30 years, a number of scientists worked to further develop the instrument, and in 1965 the first SEM was delivered to DuPont by the Cambridge Instrument Company as the “Stereoscan.”
Here you’ll experience the power of SEM in a journey of self-discovery that starts in your head, travels down through the chest and ends in the bowels of the abdomen. Along the way, you’ll see what’s normal, what happens when cells are twisted by cancer and what it looks like when an egg meets sperm for the first time. You’ll never see yourself the same way again.

Villi in the small intestine increase the surface area of the gut, which helps in the absorption of food. Look closely and you’ll see some food stuck in one of the crevices.

Lung cancer cells

This image of warped lung cancer cells is in stark contrast to the healthy lung in the previous picture.

Red blood cells
They look like little cinnamon candies here, but they’re actually the most common type of blood cell in the human body - red blood cells (RBCs). These biconcave-shaped cells have the tall task of carrying oxygen to our entire body; in women there are about 4 to 5 million RBCs per microliter (cubic millimeter) of blood and about 5 to 6 million in men. People who live at higher altitudes have even more RBCs because of the low oxygen levels in their environment.

10 Scary Sea Monsters


Stonefish
Stonefish is extremely dangerous, live primarily above the tropic of Capricorn. The reef stonefish is the most widespread species of the stonefishes family, and is known to be found in the shallow tropical marine waters of the Pacific and Indian oceans, ranging from the Red Sea to the Queensland Great Barrier Reef. They are carnivorous ray-finned fish with venomous spines that lives on reef bottoms, camouflaged as a rock. They are the most venomous known fish in the world.


Fossil fish Coelacanth 
Coelacanths belong to the subclass Actinistia, a group of lobed-finned fish that are related to lungfish and certain extinct Devonian fish such as osteolepiforms, porolepiforms, rhizodonts, and Panderichthys. Coelacanths were thought to have gone extinct in the Late Cretaceous, but were rediscovered in 1938 off the coast of South Africa. Latimeria chalumnae and the Latimeria menadoensis are the only two living coelacanth species, which are found along the coastlines of the Indian Ocean. The coelacanth has been nicknamed a “living fossil”, because it originally was known only through fossils, long before the first discovery of a live specimen. The coelacanth is thought to have evolved into roughly its current form approximately 400 million years ago.


Dragon fish 
Deep water fish species, a quiet fearsome predator with a slim body and large head and sharp fang-like teeth, eating smaller fish. Their gut is heavily pigmented, so that any luminescent organs in their prey cannot shine through their bodies and attract larger predators.


Blue-ringed Octopus
The blue-ringed octopuses is a tiny cephalopod that packs a lethal punch, are three octopus species that live in tide pools and coral reefs in the Pacific Ocean and the Indian Ocean, from Japan to Australia. They are currently recognized as one of the world's most venomous marine animals. Despite their small size and relatively docile nature, they can prove a danger to humans. They can be recognized by their characteristic blue and black rings and yellowish skin. When the octopus is agitated, the brown patches darken dramatically, and iridescent blue rings or clumps of rings appear and pulsate within the maculae. Typically 50-60 blue rings cover the dorsal and lateral surfaces of the mantle. They hunt small crabs, hermit crabs, and shrimp, and may bite attackers, including humans, if provoked.


Fang tooth fish
The fang tooth fish is a sea monster creature that looks so scary. It has only about 6 inches long, and has a large head, long teeth, and you cannot find it easy, because it lives in depths water of approximately 5,000 meters.

Killer Whales 
The killer whale, commonly referred to as the orca whale or orca, and less commonly as the blackfish, is a toothed whale belonging to the oceanic dolphin family. Killer whales are found in all oceans, from the frigid Arctic and Antarctic regions to tropical seas. Killer whales as a species have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as sea lions, seals, walruses and even large whales. Killer whales are regarded as apex predators, lacking natural predators.


Anglerfish
Anglerfishes are bony fishes named for their characteristic mode of predation, wherein a fleshy growth from the fish's head acts as a lure; this is considered analogous to angling. Some anglerfishes are pelagic (live in the open water), while others are benthic (bottom-dwelling). Some live in the deep sea and others on the continental shelf. They occur worldwide. Pelagic forms are most laterally (sideways) compressed whereas the benthic forms are often extremely dorsoventrally compressed (depressed) often with large upward pointing mouths.


Spider Crab
Tall-footed crab, is a species of marine crab that lives in the waters around Japan. It has the largest leg span of any arthropod, reaching up to 3.8 metres (12 ft) and weighing up to 41 pounds (19 kg). It is the subject of small-scale fishery..


Sperm Whales
The sperm whale is the largest species of toothed whale, with adult bulls (males) growing to be about 15–18 metres (49–59 ft) long, and weighing about 45–70 tonnes (44–69 long tons; 50–77 short tons). The two kogiid species are much smaller, at only around 2.5 to 3.5 metres (8 ft 2 in to 11 ft 6 in) in length, and weighing 350–500 kilograms (770–1,100 lb).


Giant Squid
The giant squid is a deep-ocean dwelling squid in the family Architeuthidae, represented by as many as eight species. Giant squid can grow to a tremendous size recent estimates put the maximum size at 13 metres for females and 10 metres for males from caudal fin to the tip of the two long tentacles (second only to the colossal squid at an estimated 14 metres, one of the largest living organisms). The mantle is about 2 metres long (more for females, less for males), and the length of the squid excluding its tentacles is about 5 metres. Claims of specimens measuring 20 metres or more have not been scientifically documented.

Nando Parrado

Survived airplane crash and 72 days in the Andes
72 - Days of ordeal, Nando Parrado and other survivors of a plane crash in the Andes had to endure before being rescued. Flying over the mountains on a Friday the 13th, the young men and their families who boarded the charter plane joked about the unlucky day when the
plane's wing hit the slope of the mountain and crashed. On impact, 13 passengers were
instantly dead while 32 others were badly wounded. Hoping to be rescued, the survivors waited in the freezing -37C temperature, melting snow for drinks and sleeping side by side to keep themselves warm. Food was so scarce, everyone had to pool whatever food they can find for a rationed pool. 9 days after the crash, due to dire desperation and hunger, the survivors called for an important meeting. One member proposed that they eat the dead. The 2 hours meeting ended with a conclusion. If any of them died in the Andes, the rest had the permission to use the corpse as food. After 2 weeks, their hope of being found dashed when they found out via their radio transistor that the rescue effort was called off.
On the 60th day after the crash, Nando Parrado and 2 other friends decided to walk through the icy wilderness for help. By the time they left, Nando Parrado said, the crash site was “.. an awful place, soaked in urine, smelling of death, littered with ragged bits of human bone and gristle”. Wearing 3 pairs of jeans and 3 sweaters over a polo shirt, he and his friends trekked the mountains with human flesh as their ration. Knowing that they must search for rescue, the team endured frozen snow, exhaustion and starvation, walking and climbing for 10 days before finding their way to the bottom of the mountain. The team was finally helped by a Chilean farmer who called the police for help. Parrado then guided the rescue team via a helicopter to the crash site. On the 22nd December 1972, after enduring 72 brutal days, the world found out that there were 16 survivors who cheated death, in the mountain of Andes. 8 of the initial survivors died when an avalanche cascaded down on them as they slept in the fuselage. During the ordeal, Nando Parrado lost 40 kg of his weight. He lost half his family in the crash. He is now a motivational speaker.

Sean Swarner

First cancer survivor to complete the 7-summits, the highest peaks of the 7 continents
The 29,035-foot giant known as Mount Everest tortures its challengers with life-threatening conditions such as 100 mph winds, the dramatic loss of oxygen, snowstorms, and deadly avalanches. Climbers of Everest are faced with incredible dangers, but for Sean Swarner the obstacles he overcame prior to his summiting make his story even more compelling.
Sean isn't just a cancer survivor; he is truly a medical marvel. He is the only person in the world ever to have been diagnosed with both Hodgkin's disease and Askin's sarcoma. He was diagnosed in the fourth and final stage of Hodgkin's disease at the age of thirteen, when doctors expected him to live for no more than three months. He overcame his illness only to be stricken a second time when a deadly golf ball-sized tumor attacked his right lung.
After removal of the Askin's tumor, Sean was expected to live for less than two weeks. A decade later and with only partial use of his lungs, Sean became famous for being the first cancer survivor to climb Mount Everest. After the summit of Everest, Sean had the desire and dream to continue moving forward and reaching people around the world. Climbing the highest mountain on each continent became his next goal. Proving to others that anything is possible, Sean successfully summited Mt. McKinley, to be the first cancer survivor to complete the seven summits. You can read more about Swarner's story on his 2007 book.

Randy Pausch

Inspired thousands of people with his dying speech.
Randolph Frederick "Randy" Pausch (October 23, 1960 – July 25, 2008) was an American professor of computer science and human-computer interaction and design at Carnegie Mellon University (CMU) in Pittsburgh, Pennsylvania. Pausch learned that he had pancreatic cancer, a terminal illness, in September of 2006. He gave an upbeat lecture entitled "The Last Lecture: Really Achieving Your Childhood Dreams" on September 18, 2007 at Carnegie Mellon, which became a popular YouTube video and led to other media appearances. He then co-authored a book called "The Last Lecture" on the same theme, which became a New York Times best-seller. Pausch died of complications from pancreatic cancer on July 25, 2008. In his famous speech, Pausch showed a list of his childhood dreams, and explained how he achieved each of them. His dreams were: being in zero gravity, playing in the National Football League, being the author of a World Book Encyclopedia article, meeting and being Captain Kirk, being "one of the guys who won the big stuffed animals in the amusement park", and becoming a Disney Imagineer.
He was given 3 months of life, he lived 3 more years.

Ben Underwood

The boy who could “see” with his ears
Ben Underwood was a remarkable teenager, who loved to skateboard, ride his bicycle and play football and basketball. For the most part, the Californian 14-year-old was just like other kids his age. What made Underwood remarkable was his ability to master these activities despite the fact that he was blind. Underwood had both eyes removed after being diagnosed with retinal cancer at age two. To most people's amazement upon meeting him, he seemed completely unfazed by his lack of sight, defying common stereotypes about blindness as a disability. So how did he do it? The answer is echolocation: the sonar navigation technique used by bats, dolphins, several other mammals and some birds. As Underwood moved about, he habitually made clicking noises with his tongue; these sounds bounced off surfaces and, with each return, added to Underwood's perception of his surroundings. He was so good at it that he could tell the difference between a fire hydrant and a rubbish bin, distinguish between parked cars and trucks, and — if you took him to a house he had never been to before — he would tell you he could 'see' a staircase in that corner and a kitchen in the other. He could even distinguish between different materials.
An unflinching faith in God guided Ben and his mother during his last few months as cancer spread to Ben's brain and spine. He finally died on January 2009 at the age of 16.

Liz Murray

From Homeless To Harvard
Elizabeth "Liz" Murray was born September 23, 1980 the Bronx, New York, to poor, drug-addicted, HIV-infected parents.

Though she started high school later than most students, and remained without a stable home while supporting herself and her sister, Murray graduated in only two years. She was awarded a New York Times scholarship for needy students and accepted into Harvard University, matriculating in the fall semester of 2000. She left Harvard in 2003 to care for her sick father; she resumed her education at Columbia University to be closer to him until 2006 when he died of AIDS. As of May 2008, she was back at Harvard working towards her degree with plans to graduate with a degree in Psychology in June 2009.
Her life became a movie in 2003 and she now works as a professional speaker, representing the Washington Speakers Bureau. That same gutsy strength that pulled her from the streets now transforms the lives of others, from student groups to business audiences in need of inspiration to overcome their own obstacles.
