Forests Emerge as a Major Overlooked Climate Factor
...rainforest — the world’s largest, at 5.5 million square kilometers — makes its own storms. More recent research reveals that half or more of the rainfall over continental interiors comes...
How Equality and Inequality Shape the Birds and the Bees
...we analyze how the exquisite interplay of the two processes described above orchestrates the dynamics of reproduction in social insects. In a recent Quanta article, “How Insulin Helped Create Ant...
Theorists Debate How ‘Neutral’ Evolution Really Is
...neutral theory looks even worse.” In humans, recent evidence suggests “there’s a lot more adaptation than we ever thought was present,” Kern said. Recent human evolution is largely a history...
The Brain Maps Out Ideas and Memories Like Spaces
...functions, and evidence has started to suggest that the same coding scheme — a grid-based form of representation — may underlie them. Recent insights have prompted some researchers to propose...
Researchers Rethink the Ancestry of Complex Cells
...a little over 4.5 billion years ago, and if the most recent estimates are correct, it wasn’t long before life arose. Not much is known about how that happened because...
Fossil DNA Reveals New Twists in Modern Human Origins
...than seemed imaginable a mere decade ago. But it’s one thing to say that Neanderthals interbred with the ancestors of modern Europeans, or that the recently discovered Denisovans interbred with...
Computers Evolve a New Path Toward Human Intelligence
...seen some successes, they can be more computationally intensive than other approaches such as “deep learning,” which has exploded in popularity in recent years. The steppingstone principle goes beyond traditional...
How Close Are Computers to Automating Mathematical Reasoning?
...a way that people understand? A slew of recent advances from labs around the world suggests ways that artificial intelligence tools may answer that question. Josef Urban at the Czech...
Quantum Tunnels Show How Particles Can Break the Speed of Light
Recent experiments show that particles should be able to go faster than light when they quantum mechanically “tunnel” through walls. No sooner had the radical equations of quantum mechanics been...
