Remarkably, this same mutation gives the protein an 80,000-fold higher affinity for carbon monoxide than for oxygen. Carbon monoxide from a cigarette will be selectively taken up by the mutant hemoglobin and prevent it from oxidizing and denaturing. This high affinity for carbon monoxide explained why the father showed no signs of anemia, Olson said.

In essence, the research show that sometimes Nature cannot tell the difference between the quantum and the classical (or real) worlds, and that a grey area does exist between the two worlds called classical entanglement.
Their paper—"A Higher-Order Theory of Emotional Consciousness"—addresses a notable gap in neuroscience theory. While emotions, or feelings, are the most significant events in our lives, there has been relatively little integration of theories of emotion and emerging theories of consciousness in cognitive science.
Existing work posits that emotions are innately programmed in the brain's subcortical circuits. As a result, emotions are often treated as different...

When the researchers apply a force on the soft side of the metamaterial, it easily induces rotations of the squares and diamonds within the structure, but only in the near vicinity of the pressure point, and the effect on the other side is small. Conversely, when they apply the same force on the rigid side, the motion propagates and is amplified throughout the material, with...

For example, imagine a hockey forward speeding across the ice towards the goal. As the forward approaches, he must dodge the other team's defense and find an opening to shoot the puck past the goalie. The forward sees two openings. Within a split second, neurons in the hockey player's motor cortex fire and encode the muscle commands needed to take both of the two possible...

even those of us who seem to have two left feet have got rhythm—in our brains. From breathing to walking to chewing, our days are filled with repetitive actions that depend on the rhythmic firing of neurons. Yet the neural circuitry underpinning such seemingly ordinary behaviors is not fully understood
"It's still very difficult to contemplate how large groups of neurons with literally billions if...

Imagine you are standing in a grocery store buying apple juice. Unfortunately, all of the crates are half empty because other customers have removed individual bottles at random. So you carefully fill your crate bottle by bottle. But wait: The neighboring crate is filled in exactly the opposite way! It has bottles where your crate has gaps. If you could lift these bottles in one...

Physicists from the Faculty of Physics at the University of Warsaw have developed a holographic atomic memory device capable of generating single photons on demand in groups of several dozen or more. The device, successfully demonstrated in practice, overcomes one of the fundamental obstacles towards the construction of a quantum computer.

When matter changes from solids to liquids to vapors, the changes are called phase transitions. Among the most interesting types are more exotic changes—quantum phase transitions—where the strange properties of quantum mechanics can bring about extraordinary changes in curious ways.
