According to Formula1, the most common type of injury is head and neck injuries. Formula One has attempted to reduce this type of damage by requiring very high standards for the drivers' helmets. The first need is that a Formula One helmet be exceedingly light. This advancement creates the problem of developing a product that is also as tough as it has to be. The helmets must pass a series of fragmentation and deformation tests to guarantee that they fulfill the stringent criteria. Because of its strength, carbon fibre is the principal material used to build Formula One helmets. The exterior shell is made up of two layers, the majority of which are made of carbon fibre.

The blue whale is the world's largest living creature, dwarfing even the largest dinosaurs. Blue whales can grow to be over 100 feet long and weigh more than 100 tonnes. Their hearts are the size of a small car and can weigh up to 1,300 pounds. Blue whales have massive arteries that pump blood through their massive hearts and into their vital organs, which is unsurprising. These arteries are so large that a fully grown human could swim through them; however, you should not attempt this.

Formula One cars aren't only about speed and power. They are among the safest vehicles on the market. There have been many F1 collisions throughout the years, and most of them have not been fatal. The vehicles are also quite uncomfortable, and it requires a great deal of stamina to compete for hours without becoming tired. According to Wired, an F1 driver may survive an incident in which the car goes from 100 mph to a complete stop in 2 seconds. For a car to be qualified for Formula 1 racing, it must meet hundreds of safety criteria. The driver's cockpit should be safeguarded as well.

In 1935, humans introduced the cane toad to Australia to help eradicate the cane beetles that were eating all of the sugar cane crops. The plan backfired. Cane toads increased in numbers and territory, killing predators and depleting food sources for native species.

Death can occur in humans within 15 mins.

Only 9-35 adults remain in the wild at Ball’s Pyramid, Lord Howe Island.

The venom in one bite is thought to be enough to kill 100 adults.

Quokkas love to approach the humans who visit Rottnest with their cheeky grins. As well as giving them the cute factor, a quokka's smile helps them cool down.

The salt-water crocodile grows to 6m or more and has the world's highest jaw pressure: 3,000 pounds per square inch.

It has over 300 native mammals, including marsupials, monotremes, and placental mammals.

This is more than anywhere else in the world due to Australia's isolation from other continents.

Anovulatory (absence of egg release from the ovary) infertility occurs in almost 75% of PCOS patients. Most PCOS patients conceive either spontaneously or with treatment for egg release with either oral medications or injections. 

Weight loss reduces the symptoms and the long-term complications. Thus, it plays a major role in the treatment of PCOS.

PCOS patients have insulin resistance and are at increased risk of developing Diabetes mellitus. However, the actual cause and the effect are still not known. 

PCOS patients can be treated and effectively managed. Weight reduction by diet, exercise, and lifestyle modification play a key role. Weight loss of around 2-5% decreases testosterone (male hormone) by 21% and women may resume regular ovulation. Lifestyle modifications like avoiding alcohol, smoking, and psychosocial stressors add to the disease modification.

There are long-term consequences. A three-time increased risk of Impaired Glucose Tolerance and a seven-fold increase in Diabetes mellitus. Increased risk of Lipid abnormalities. Increased risk of hypertension and cardiovascular disease. Increased risk of endometrial carcinoma.

The following are the criteria for the diagnosis of PCOS: Anovulatory infertility decreased flow during menses; excess facial hair; Polycystic ovaries on ultrasound. The presence of any two of the above three criteria is necessary for the diagnosis of PCOS. Even if polycystic ovaries are not there, with the presence of the other two criteria, it is still diagnosed as PCOS.

Young PCOS patients with regular menstruation need no hormonal treatment. Irregular menstruation and patients anxious to conceive need to be treated accordingly.

It takes one particularly terrifying creep to inspire Hannibal Lecter, Norman Bates, and Leatherface, but that's the legacy left by horrifying serial killer Ed Gein. When he was finally caught and his house of horrors in Plainfield, Wisconsin, discovered, police found masks and lampshades made from human skin, among plenty of other atrocities. His astonishing depravity proved a source of creative inspiration.

If you're looking to score big box office bucks, stay away from Mars. The two biggest money losers of all time both take place on that planet, with the 2012 sci-fi bomb John Carter holding the No. 2 spot with a loss of almost $127 million, outdone only by Mars Needs Moms, from a year earlier, which lost its studio more than $143 million—the worst ROI ever.
