Artificial intelligence (AI) is beginning to reshape our world—so it's incumbent upon us to understand just what we mean by that expansive phrase, and how it all works. We break down the forms of AI, machine learning, and deep learning, and examine just a few of the ways this technology is being applied in real-world situations.

According to the World Economic Forum, solar power is now cheaper than fossil fuels for new energy. Renewable energy has reached a tipping-point of sorts—massive investment, falling installation costs, and advancing tech is beginning to reap dividends. Now, a future of clean, renewable power is finally within reach.

Researchers have captured a "movie" of the energy transfer that takes place during photosynthesis, disproving a long-held belief about the quickest part of the process. By bettering our understanding of natural photosynthesis, we can improve our artificial systems, which could provide the world with a free, unlimited energy supply.

Since the flight of the X-15 in 1967, hypersonic research in the United States has stagnated. The revival of NASA's dormant X-Planes program, and renewed interest by the US military and other entities—to say nothing of a brewing "aerospace race" by the world's leading powers—promises that the coming decades will see a renaissance of hypersonic research and development.

Quantum mechanics and general relativity, the twin monuments of 20th Century genius, have done a remarkable job of explaining the way our universe works. But at the edges of knowledge, we're learning that they're only facets of a much larger picture. Attempts to fashion a quantum theory of gravity, which unites the quantum and general relativistic realms, have resulted in a flurry of recent weird breakthroughs—including the bizarre notion that time might be the byproduct of entangled qubits residing on the temporal boundaries of the universe.
