Sentinelese Tribe – The most Dangerous and Isolated



The Sentinelese (also called the Sentineli or North Sentinel Islanders) are the indigenous people of North Sentinel Island in the Andaman Islands of India. One of the Andamanese peoples, they resist contact with the outside world, and are among the last people to remain virtually untouched and uncontacted by modern civilization.

The Sentinelese maintain an essentially hunter-gatherer society subsisting through hunting, fishing, and collecting wild plants. There is no evidence of either agricultural practices or methods of producing fire.The Sentinelese language remains unclassified and is not mutually intelligible with the Jarawa language of their nearest neighbors.The Sentinelese are designated as a Scheduled Tribe.



The precise population of the Sentinelese is not known. Estimates range from fewer than 40, through a median of around 250, and up to a maximum of 500. In 2001, Census of India officials recorded 39 individuals (21 males and 18 females); however, out of necessity this survey was conducted from a distance and almost certainly does not represent an accurate figure for the population who range over the 59.67 km2 (14,700 acres) island.The 2011 Census of India recorded only 15 individuals (12 males and three females).Any medium- or long-term effect on the Sentinelese population arising from the 2004 Indian Ocean earthquake and resulting tsunami is not known, other than the confirmation obtained that they had survived the immediate aftermath.


The Sentinelese and other indigenous Andamanese peoples are frequently described as negritos, a term which has been applied to various widely separated peoples in Southeast Asia, such as the Semang of the Malay Peninsula, the Aeta of the Philippines archipelago, as well as to other peoples in Australia including former populations of Tasmania.[citation needed] The defining characteristics of these "negrito" peoples (who are not a monophyletic group) include a comparatively short stature, dark skin, and afro-textured hair.

Although no close contacts have been established, author Heinrich Harrer described one man as being 1.6 metres (5 ft 3 in) tall and apparently left handed.

Youngest Mother In Medical History Still Refuses To Reveal The Truth 78 Years Later


In 1938 the youngest mother in medical history gave birth to her first baby, a son she named Gerardo. The young mother, Lina Medina, was only a child herself - she was just 5 years old.
It seems impossible, but it's true.
The young girl's parents brought their daughter to the local hospital in Pisco, Peru with grave concerns that she was suffering from a huge tumor in her stomach.


To their shock, doctors informed them that she was actually seven months pregnant. She gave birth to her son by cesarean section on May 14, 1939.
She was five years, seven months and 12 days old.

Doctors confirmed that Lina's incredible pregnancy was possible because she was born with a rare condition known as "precocious puberty."
This condition is early-onset puberty.
She experienced her first menstrual cycle between two and three years old. By the time she was five, she had fully developed breasts, pelvic widening and advanced bone maturation....
Since she was so young, sexual abuse was immediately suspected. Her father was arrested on suspicion of rape and incest, but he was released due to lack of evidence.
Some suggested that she might have been present at one of the indigenous festivities celebrated in the Andean villages. "These often ended in orgies where rape was not uncommon."

To this day, Lina has never revealed the father, nor the circumstances surrounding her impregnation. Now, at 83 years old, she still refuses to give interviews or speak about the past.

single drop of seawater


You know when you’re horsing around at the beach and accidentally swallow a nasty gulp of salt water? Well I hate to break it to you but that foul taste wasn’t just salt. Photographer David Littschwager captured this amazing shot of a single drop of seawater magnified 25 times to reveal an entire ecosystem of crab larva, diatoms, bacteria, fish eggs, zooplankton, and even worms. Read more about what you probably don’t want to know at Dive Shield. We do admit the little crab larva in the lower right-hand corner is pretty darned cute.

Marine Microfauna – part of the contents of one dip of a hand net. The magnification was 2x life size, meaning that the actual frame size was a half inch high, so depending on how big the image is on your screen you can calculate the magnification as you see it. To keep as much focus as possible the sample is in as little water as possible just covering the bottom of a 60mm petri dish. That takes about 15 drops of water, but you are only seeing a very small portion of the total sample.

The slide was photographed aboard the NOAA Ship Oscar Elton Sette off Kona, September 20, 2006, and you can see a detailed listing of the wildlife on JellyWatch.

malaysian exploding ant



Camponotus saundersi is a species of ant found in Malaysia and Brunei, belonging to the genus of Carpenter ants. Workers can explode suicidally and aggressively as an ultimate act of defense, an ability it has in common with several other species in this genus and a few other insects. The ant has an enormously enlarged mandibular (jaw) gland, many times the size of a normal ant, which produces defense adhesive secretions.


Its defensive behaviours include self-destruction by autothysis, a term coined by Maschwitz and Maschwitz (1974).Two oversized, poison-filled mandibular glands run the entire length of the ant's body. When combat takes a turn for the worse, the worker ant violently contracts its abdominal muscles to rupture its gaster at the intersegmental fold, which also bursts the mandibular glands, thereby spraying a sticky secretion in all directions from the anterior region of its head.The glue, which also has corrosive properties and functions as a chemical irritant, can entangle and immobilize all nearby victims.

Direct observation by Jones (2004) found that C. saundersi adhesive secretions range from bright white at the end of the wet season to cream or pale yellow in the dry season and start of the wet season. These variations in coloration represent a shift in internal pH, likely due to seasonal changes in diet.

Dumb cane...monther-in-law's tongue



Dieffenbachia  is a genus of tropical flowering plants in the family Araceae. It is native to the New World Tropics from Mexico and the West Indies south to Argentina. Some species are widely cultivated as ornamental plants, especially as houseplants, and have become naturalized on a few tropical islands.

Dieffenbachia is a perennial herbaceous plant with straight stem, simple and alternate leaves containing white spots and flecks, making it attractive as indoor foliage. Species in this genus are popular as houseplants because of their tolerance of shade. Its English names, dumb cane and mother-in-law's tongue (also used for Sansevieria species) refer to the poisoning effect of raphides, which can cause temporary inability to speak. Dieffenbachia was named by Heinrich Wilhelm Schott, director of the Botanical Gardens in Vienna, to honor his head gardener Joseph Dieffenbach (1796–1863).

Toxicity

The cells of the Dieffenbachia plant contain needle-shaped calcium oxalate crystals called raphides. If a leaf is chewed, these crystals can cause a temporary burning sensation and erythema. In rare cases, edema of tissues exposed to the plant has been reported. Mastication and ingestion generally result in only mild symptoms. With both children and pets, contact with dieffenbachia (typically from chewing) can cause a host of unpleasant symptoms, including intense numbing, oral irritation, excessive drooling, and localized swelling.However, these effects are rarely life-threatening. In most cases, symptoms are mild, and can be successfully treated with analgesic agents, antihistamines,or medical charcoal. Gastric evacuation or lavage is "seldom" indicated. In patients with exposure to toxic plants, 70% are children younger than 5 years.

Stories that Dieffenbachia is a deadly poison are urban legends.

Teacher Notices Triplets Only Talk To Each Other, Then Discovers They’re 3 Starving Orphans


When the Yeckes Triplets arrived at Valley High School in Las Vegas, they didn’t seem to care about school. Haley, Kassidy, and Sierra were defensive toward teachers, counselors, and authoritative figures in general. They had attendance issues and were failing their classes. The girls kept to themselves and only relied on each other.

Instead of turning its back on them, the school introduced the triplets to the GEAR UP Program, which provided them with extra care and support. The more the triplets felt safe with the GEAR UP staff, the more they improved their attendance and grades. They also finally opened up about their situation — and it was more horrifying than anyone could have imagined.

The triplets’ mother died when they were just 3 months old. When they entered sixth grade, their father was incarcerated. They went to live with a grandmother, but since she didn’t believe in schooling, they didn’t go to school until they were age 8.

When their father got out of jail, he moved with the girls. But he would leave them to fend for themselves for weeks at a time. Their stint with him ended after their house was shot up while they were home alone.

The girls moved in with their grandparents, who were terribly neglectful. The triplets spent portions of their lives homeless, without food, clothing, and transportation.

But with the help of their GEAR UP teachers, the triplets overcame the loss of both parents and homelessness. They went on to raise and maintain their GPA above 3.0 while taking advanced courses, participating in activities and working jobs as “unaccompanied minors.”

Now, all three sisters are bound for college. Their amazing story inspired the FOX5 Surprise Squad to be there in secret for their graduation day.

In the video below, the Yeckes Triplets are pulled aside after receiving their diplomas… and the entire school watches on as they’re given the surprise of their life.
