Tsar Bomba (The King of Bombs)

This was one big mother fucker.
The bomb was built and eventually tested on October 30, 1961, on the west coast of Novaya Zemlya Island (Arctic Sea).

Estimated to have had a yield of 50,000,000 TONS of TNT.

Heat from the explosion was enough to cause 3rd degree burns 62 miles away.

Mushroom cloud was nearly 7 times taller than Mt. Everest (~40 miles).

The seismic shock from the blast could be measured on its third passage around the Earth.

The fireball from the explosion was nearly 5 miles in diameter:

*According to its Wiki (seems legit for what little math I did):  the entire fission-fusion process, lasting around 39 nanoseconds, was about 5.4 yottawatts (5.4 X 10^24), equivalent to about 1.4% of the power output of the sun.

A comparison to other notable bombs:

Here's something fun. Type your address or any address that you can find on google maps, and drop a bomb there and see how big the blast and fallout is:

Exercising for Only 30 Second bursts Best for Health

Short bursts of intense exercise every few days could dramatically cut the risk of Type 2 diabetes and heart disease, according to an expert.

Rather than slaving away for hours in the gym, people should focus their attention on quick "sprints" with each workout lasting just a few minutes.

James Timmons, Heriot-Watt University professor of exercise biology has studied the effects of quick exercise.

He recommends 4 x 30 second sprints on an exercise bike three times a week.

He said people could reduce their risk of diabetes and heart disease substantially with short, intense workouts - with such "time-efficient" exercising appealing to busy workers.

An intense workout for a few minutes may keep heart disease and diabetes at bay
In his study, published in the journal BMC Endocrine Disorders, 16 men exercised for three sessions a week for two weeks.

Each session was made up of 4 x 30 second sprints on an exercise bike.

This involved the men going as fast as they could for 30 seconds and then taking a few minutes of complete rest between each sprint.

After two weeks, Prof Timmons said the results were "substantial", with a 23% improvement in insulin function.

While his research focused on young men, Prof Timmons said it would work for people of all ages and for both men and women.

He said: "This study looked at the way we break down stores of glycogen.

"Think about diabetes as being glucose circulating in the blood rather than stored in the muscles where it should be.

"If we take out the glycogen from the muscles through exercise, then the muscles draw in that excess glucose from the blood."

Intense contractions

He added: "If you go for a jog or a run you oxidise glycogen but you are not depleting the glycogen in your muscles.

"The only way to get to this glycogen is through very intense contractions of the muscles.

"If we can get people in their 20s, 30s and 40s doing these exercises twice a week then it could have a very dramatic effect on the future prevalence of diabetes."

He said the effects were bigger than the traditional "one hour of running per day".

The exercise routine is known as "high-intensity interval training" or HIT for short.

Prof Timmons said current guidelines on how much exercise people should take may need revising.

Diabetes UK research manager Victoria King said short duration, high-intensity training improved insulin action in young healthy males but the research had only been undertaken in a small group of people without diabetes.

She said: "Whilst the improvement in the control of insulin action in those who undertook the training is interesting, it's limited at this stage as to what we can learn."

Supposed hybrid son of a Yeren (Chinese Bigfoot)

This person is the result of a supposed rape of his mother by a Yeren. His mother went missing for months. When she came back to the village, she hardly spoke, but claims she was raped by the yeren. She never spoke about it after that. Scientists have asked her if they could study him, but she always just asked them to go awat and leave them alone.

The Yeren, variously referred to as the Yiren, Yeh Ren, Chinese Wildman or Wildman of China, Man-Monkey, or Man Bear, is said to be an as yet undiscovered hominid residing in the mountainous and forested regions of China's remote Hubei province.

The Yeren is sometimes described as a large, hairy bipedal hominoid, and some believe that this animal, or its close relatives, may be found around the world under different regional names, such as Bigfoot of the United States and Canada, the Yeti of Tibet and Nepal, and the Yowie of Australia.
