Our super friends in the animal world possess so many hidden superpowers. In the third episode we meet heat-seeking dogs, GPS-outfitted cats, and a sporty goldfish with squad goals.
When we think we know them inside out, dogs surprise us with something new. what sensory superpower have dogs been hiding all this time? They have a thermal sensor in the tip of his nose. In the wild, a dog could use his thermal nose to spot the heat of a prey animal, allowing him to hunt even if his other senses were impaired. It also explains that uncanny knack for stealing a warm seat.

All of our pets survived for thousands of years in the wild without any help from us, and this has led them to develop astonishing athletic abilities which we sometimes take for granted. As greyster dogs and endurance champ tortoises.
Dog scootering uses one or more dogs to pull a human riding an unmotorized scooter. Greysters are a naturally-athletic breed that can run at 20 miles per hour for five miles while handling these carriages. No other animal can run at this speed, exerting this power, and expending this energy for so long. So, what's their secret? Greysters' stride length can be a staggering 16 feet and they are super efficient at absorbing and using oxygen. Greyster dogs have nearly twice mitochondria inside their cells than humans.

The unearthing of a gruesome grave filled with thousands of skeletons at the beach of Kamakura in Japan could be about to unlock the true extent of the merciless violence and mystery surrounding the true origins of one of the most feared and revered warriors of all time: the Samurai.
In the Middle Ages, Kamakura was the capital of Japan. The 'Shogun', a kind of aristocratic military dictator, ruled here. This shogunate ended in 1333 with the Battle of Kamakura. A drastic event in Japanese history, because this resulted in not only political, but also social, philosophical and technical innovations. The remains of the samurai warriors who fell near Kamakura now provide scientists with detailed insights into the time of the Kamakura shogunate and the bloody conflict between the shogun and the emperor.
The chilling burial ground dates back to 1333. Kamakura was one of the most heavily fortified regions of Japan. When the Emperor became angered by the growing powers of the ruling Hojo family, he sought to retake control of the region, setting the stage for a war that would change the shape of the nation. Among over 4000 sets of remains, six have a unique story to tell: the husband and wife involved in a sword fight to the death; the warrior monk; a peasant boy soldier; and members of the ruling Hojo family, captured and decapitated, with their heads displayed as trophies of victory. These remains reveal the secrets of the Samurai, their ferocious fighting skills and their merciless killing techniques.

Clarkson is ready to submit his application for his farm restaurant; he must use gentle navigation and respect for bureaucracy in order to keep his interests afloat. This, of course, is not easy for Jeremy, so he must be careful. Faced with Council powers that be, Jeremy uses two of his greatest skills: diplomacy and respect for red tape.

The results of the TB test are in... but just as important is the fact that numerous calves are scheduled to be born in the next couple of weeks. The first few happen very quickly in the dead of night before Jeremy's woken up, but soon he and Kaleb are dealing with some very challenging situations. Jeremy also meets local farmers to discuss a farmers' co-operative to supply the restaurant - much-needed by some who are really struggling - because the clock is counting down to Decision Day, when the Council will hold a public meeting to decide the fate of Jeremy's restaurant.
After weeks of waiting, the day of judgement for Clarkson's restaurant is at last here. He and Charlie set off to put their case to the powers that be. Is it a Yes? Or is it a No?
