Every morning, as I prepare his food, our black-and-white lurcher, Ozzy, looks up at me with the warmest of eyes. He will give me the eyebrows too. The cutest of smiles. He will cock his head in expectation of food, and seems to know that I will give it to him, devoted as I am.
“Does he really love me?” I wonder, as he waits patiently for his tripe with his tail wagging furiously. Because sometimes I have the vaguest feeling I am being hustled. Like I am one of Pavlov’s dogs and he is Pavlov, conditioning me with cuddles and baby-faced eyes to do nice things for him.
Is this love or something else? Can dogs ever really love their humans like we love them? It turns out that questions like these have a rich scientific history, with an exciting conclusion that could forever change our relationship with dogs.
The story of dogs and emotions begins in the Victorian era, when the question sparked one of the first culture wars in history. It involved banners, placards and leaflets. It had burning effigies and vandalised statues, angry marches and speeches in packed-out town halls. At one point, hundreds almost fought in the street. They were ready to fight about whether emotions like love were uniquely human or common to many animals, particularly social mammals such as dogs.

Do We Finally Know How the Egyptian Pyramids Were Built? - A number of breakthrough studies are beginning to paint a picture of how these wonders of the world were built, but much of the story still remains a mystery...
A number of breakthrough studies are beginning to paint a picture of how these wonders of the world were built, but much of the story still remains a mystery...How the Egyptian pyramids were built has long been a mystery. Constructed as tombs for the pharaohs over 4,000 years ago, more than 100 of them remain. The largest one, the Great Pyramid of Giza, was originally 147m tall (482ft). It's made up of about 2.3 million stone blocks, each weighing between 2.5 and 15 tonnes, and would have had to be transported to the building site and lifted into place with techniques available at the time. To put this into context, it's akin to lifting a double-decker London bus to the top of St Pauls Cathedral a few million times.
An Artificial Heart Inspired by Plumbing - Mechanical circulation could revolutionise transplant design and reduce waiting lists
Mechanical circulation could revolutionise transplant design and reduce waiting lists. In July, this artificial heart was successfully implanted, for the first time, into a patient with end-stage heart failure. Built by The Texas Heart Institute (THI) and BiVACOR, the replacement organ has been dubbed the Total Artificial Heart (TAH). Although, being an implant rather than transplant, it's designed to temporarily support patients while they wait for a real heart transplant.
