Animal Sex Is Dangerous and Horrifying. So Why Does Sex Exist at All?
You’ve probably heard about duck penises—that they’re shaped like corkscrews, and that females have vaginas that corkscrew in the opposite direction. That one’s easy. But animal sex gets a whole lot weirder, with sexual dismemberment, servitude, and freaky parasitism that makes the duck’s corkscrew seem practically…um…straight? The current issue of our magazine is all about \[…\]

From the Phenomenology to the Mechanisms of Consciousness: Integrated Information Theory 3.0
From the Phenomenology to the Mechanisms of Consciousness: Integrated Information Theory 3.0
Author Summary Integrated information theory (IIT) approaches the relationship between consciousness and its physical substrate by first identifying the fundamental properties of experience itself: existence, composition, information, integration, and exclusion. IIT then postulates that the physical substrate of consciousness must satisfy these very properties. We develop a detailed mathematical framework in which composition, information, integration, and exclusion are defined precisely and made operational. This allows us to establish to what extent simple systems of mechanisms, such as logic gates or neuron-like elements, can form complexes that can account for the fundamental properties of consciousness. Based on this principled approach, we show that IIT can explain many known facts about consciousness and the brain, leads to specific predictions, and allows us to infer, at least in principle, both the quantity and quality of consciousness for systems whose causal structure is known. For example, we show that some simple systems can be minimally conscious, some complicated systems can be unconscious, and two different systems can be functionally equivalent, yet one is conscious and the other one is not.

The Moon's Two Sides Look So Different Thanks To 4.5 Billion-Year-Old Physics
If you’ve ever looked up at the brightest and closest celestial object in the night sky, our Moon, you’ve probably noticed how different some parts of it appear to be from others. And if you’ve ever taken a look at it through a telescope, especially if it’s not in its full phase, you’ve very likely n

'Zeno effect' verified—atoms won't move while you watch
One of the oddest predictions of quantum theory – that a system can't change while you're watching it – has been confirmed in an experiment by Cornell physicists. Their work opens the door to a fundamentally new method to control and manipulate the quantum states of atoms and could lead to new kinds of sensors.
