Explaining consciousness is one of the hardest problems in science and philosophy. Recent neuroscientific discoveries suggest that a solution could be within reach – but grasping it will mean rethinking some familiar ideas. Consciousness, I argue in a new paper, may be caused by the way the brain generates loops of energetic feedback, similar to

Giant pandas are by nature solitary animals, but that doesn’t mean they aren’t well-versed in the language of love. Far from it. When spring arrives and these giant creatures get frisky, effective communication is one of biggest turn-ons. And these pandas know exactly how to express their interest. By recording giant pandas (Ailuropoda melanoleuca) before,

One of the difficulties in developing quantum computers to their full potential – and there are quite a few – is cutting out interference. With technology as delicate as this, any kind of environmental noise or imperfection that affects the careful balance of a quantum computer could cause havoc with its calculations. To overcome this

Neanderthals are often depicted as barrel-chested, hunched-over cavemen, but a close inspection of their fossils is telling a different story. For the first time, an international team of researchers has reconstructed the ribcage and upper spine of a Neanderthal man who died roughly 60,000 years ago. The findings suggest that contrary to popular images, these
