Associate Professor Ayaka Takimoto of Hokkaido University, graduate student Kosuke Nakamura of The University of Tokyo, and former Professor Toshikazu Hasegawa of The University of Tokyo have established that horses, like dogs, can read and understand human faces and emotions.
They found that horses who looked at human faces while listening to recorded voices were able to recognize when the face was happy, but the voice recording was scolding and knew that the voice did not match the face. They were able to recognize happy faces with happy recordings and angry faces with angry recordings.
What was also interesting was that it did not matter if the horse knew the person or not. They were still able to match the correct facial expression with the correct voice.
Horses do have strong communication capabilities. They can read the emotions of other horses using facial expressions, contact calls, and whinnies. With this in mind, it is not surprising that with their long association with humans, that they have learned to read us. It would be reasonable to assume that other members of the equine family have the capability to read us too.
Dr. Catrin Rutland, Assistant Professor of Anatomy and Developmental Genetics at Nottingham’s School of Veterinary Medicine and Science, led a study with the Kazan Federal University and the Moscow State Academy of Veterinary Medicine and Biotechnology that discovered the use of DNA injections to cure injury related lameness in horses.
Within two months the horses were 100% restored to their pre-injury state. The gene therapy uses a combination of the Vascular Endothelial Growth Factor gene VEGF164, to enhance the growth of blood vessels and bone morphogenetic protein 2 (BMP2), which plays an important role in the development of bone and cartilage.
The genes were taken from horses and cloned into a DNA, which was not rejected by the horses that were treated since it was horse DNA. The current therapies for lameness at best has only a 40 to 80% success rate and can take up to 6 months for the horse to recover.
The DNA treatment resulted in the tissues in the horse’s limbs to be fully recovered. As a follow-up the horses were examined a year later and found to be 100% fit, active and pain free.
Not only is this good for horses, but the researchers hope that with further research, the method can be used on all animals, including people who suffer from similar injuries.
