Dogs are more than just pets; they're a member of the family... right? If so, you'd think that they'd want to look after you just as much as you look after them. But, unfortunately, a study has found that this may not be the case.
Dogs won't give food to a human, even if that person gave them some food first, researchers at the University of Veterinary Medicine in Vienna, Austria, have found.
Previous studies have shown that dogs recognise cooperative and uncooperative humans, and that they would help dogs that had helped them previously. So, the team expected to find that their test subjects would put these two things together and show 'reciprocal altruism' —that is, doing a good thing in return — to a human who had given them food first.

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.
